EMF Readings - LEED Platinum Home Progress Report

Contractor's Notes 1-10-11

Hello Everyone,

For this week the guys will finish up the 2nd floor, install the 3rd floor LVLs, install the attic floor and prep the basement.

The windows will be delivered the 12th (hoping that the snow storm does not come). If the weather is too bad it will probably be Friday or early next week.

For Wednesday’s meeting, if the weather is bad, Thursday is fine and does not necessarily have to be on site. The topics we would like to address are:

Quick review of heating (I will forward Ruhnke’s numbers to everyone tomorrow so that we can have a quick discussion).

Electrical, Peter picked up the plans and I will give him the EMF reader once I receive it. He said the price will probably stay in the same ballpark. I think we should invite him to the next meeting to walk through the site with us.

The beam placement in the attic around the chimney.

Verify the basement plans regarding placement of walls.

Tom the cabinet maker is going to meet Jon and Ian on site to do a walk through and finalize contracts.

On a very good note, the building inspector told the zoning inspector that he needed to come out to the site to see what has been accomplished. Woody was very nice and very appreciative of all of the steps taken to stay within the town’s guidelines. It was a very positive meeting that I think will help us in the future.

A New Year ~ 2011 - LEED Platinum Home Progress Report

Contractor's Notes 1-03-11

Happy New Year Everyone!

For this week’s rundown:

All week is framing. The goal is to have the 2nd floor completely framed up so that we can start in on the 3rd floor and roof next week. Weather permitting.

Our goal is to get the windows delivered next week, the plumber out the week of the 17th to start roughing and the electrician the following week to start his roughing.

For Wednesday’s meeting, Anthia does not have child care and would like it to be at her home. If that is still OK Anthia, would you mind confirming and sending us the address?

The topics we would like to discuss are:

Heating. We should have a firm decision within 2 weeks. Ruhnke is getting his numbers to me tomorrow so I can bring those to the meeting.

Roof. We would like to use 5/8” CDX and EPS.

Front Door. We plan on installing the windows and doors the week of the 24th.

LEED Checklist. How much is done and what paperwork is needed.

Cabinetry.

Anthia would like to discuss to lighting and hardware fixtures.

Does anyone have anything to add?

Christmas time... - LEED Platinum Home Progress Report

Contractor's Notes 12-20-10

Hello Everyone,

This week the guys are working on the framing all week. They do plan on taking Friday off.

We have sent out the new heating option out to our subs and will hear back about the pricing. One sub also mentioned that there is a company in Vermont that looks and performs like Runtal. He can get us a quote for both. Once we have those, we can put them all on the table to compare.

I have talked to Klaas about the tree in the backyard. He is very excited about the job and said all he needed was for an arborist to cut and load the tree on his truck, then he can cut and dry it for $1.50 a board foot. Both he and Tom are going to get us pricing on milling it. Once we have the milling numbers, I will let you know. I did leave a message for O’Neill’s to see if they would be agreeable to cut and load the tree, I have yet to hear back.

I am not sure if I can make tomorrow’s meeting, my son had to stay home today due to a stomach bug, so if it is alright can we postpone the weekly meetings until after the new year?

A and S, have a safe and fun visit. To everyone, Merry Christmas and Happy New Year!

Steel Beams and Framing - LEED Platinum Home Progress Report

 

 

Contractor's Notes 12-13-10

For this week:

Monday- cut back ceiling to accommodate the beam, refuse handling, meet the engineer, demo the entire downstairs, build temp walls

Tuesday- grout the sill, cut footings for the basement beam, install basement LVL, set the sills

Wednesday- frame the floor, get the driveway side built, cut 1st floor joists for steel

Thursday- inspection, steel install, last of the concrete until the spring

Friday- spillover

For Wednesday’s meeting we would like to discuss HVAC, the front staircase, the engineering for the beams and columns, the LEED checklist and Peter can come out to talk about EMF reduction for the electrical.

The salvaged 1.5” insulation for the slab was delivered today.

More of the steel beams will be delivered Wednesday.

The remaining LVLs will be delivered at the end of the week as well. They are all urea-formaldehyde free.

The SIS (structural insulation system) panels will be delivered either this Friday or next Monday.

 

 

 

LEED Intern - LEED Platinum Home Progress Report

12-6-10

Hello Everyone,

A quick rundown for this week:

Monday and Tuesday: finish up adhering the recycled insulation boards to the foundation, some backfill

Wednesday: pour the front porch

Thursday and Friday: backfill along foundation, start setting sill plates and preparing for steel beams

The basement steel beams will be delivered toward the end of this week.

We did source window sill pans that are easily available.

The FSC lumber has been delivered, racked and covered in the backyard.

For the meeting tomorrow, we would like to discuss the direction of electrical and heating. We will need those 2 mechanics sorted out shortly, because once we start framing, we will need them to start their roughing.

Ann, I have revised the timeline and can bring a copy down for you tomorrow.

Barbara, our LEED intern, is available tomorrow as well. She was wondering, Elizabeth, if you could list her on the project, so that she can access all of the points and paperwork. Or should I direct her to Josy Taylor?

Foundation is Done! - LEED Platinum Home Progress Report

Contractor's Notes 11-29-10

Hello Everyone,

Just a quick note before tomorrow’s meeting:

The foundation has been poured. The guys will be stripping the forms tomorrow.

The front porch footings passed inspection.

The recycled insulation boards are getting delivered tomorrow and installed Thursday. Once they are installed the inspector will come back out (informally he said it looked great).

The FSC lumber is getting dropped off Friday, then they can start framing.

Thanksgiving - LEED Platinum Home Progress Report

Contractor's Notes 11-22-10

Hello Everyone,

A quick update for this week:

The guys will finish the forms today, Wednesday, and are having the concrete truck come out on Tuesday to pour. Once the foundation is poured, you will see much progress.

Since the concrete truck is coming on Tuesday, we would like to hold off until spring for the wall. I am sorry for the stress we may have caused in trying to get it done now, we thought that if it were straight forward enough we could pour everything now. It seems like there may have to be a shift in the wall from the driveway that would effect the arch, so we will visit that at a later date. For now we would like to focus on the foundation and getting the walls up.

The recycled insulation for the foundation walls will be delivered next week as well as the FSC framing. We were planning on storing the framing inside the house, that way it will be dry and off the ground.

There is also more excavation work going on there today.

I will check back in on Monday, and will see you out at the site on Wednesday.

Have a great Thanksgiving

LEED Checklist- Getting Down to Details - LEED Platinum Home Progress Report

Contractor's Notes 11-15-10

Hello All,

A rundown for this week:

Monday through Wednesday the guys will be getting the foundation walls built and poured

Thursday and Friday the excavator will be back on site moving around earth

Jon has called both the engineer and Loretta about drainage. The engineer said they were going to go back to the drawings to address the footings and sump pumps and will contact us shortly.

Loretta said she can get the drawings to us shortly for the back yard. Jon gave her a Thursday deadline.

The insulation for the foundation walls has been ordered. They are recycled from factories that were getting torn down and coming from MA.

The lumber order has also been placed. All pressure treated lumber is ACQ, all nominal lumber is FSC and all plywood is FSC mixed sources. We are planning on storing it in the house so that it will not get wet or in the way. 

We do have a LEED intern who is working with us to handle all of the paperwork (she also happens to be the client whose project we completed before yours). We spoke about the photo documentation for LEED, which she has already started. She can come out once a week and was interested in coming out when we hold our weekly meetings. I wanted to make sure that everyone is comfortable with that.

Elizabeth, I got the basement stair drawings and will pass that on to Ian and Jon.

LEED Checklist- Getting the Details Pinned Down.

While Demolition is still going on we meet in our office to go through the LEED checklist adn try to decide - for sure- some of the details that are outstanding. Generally our meetings are with the owner and the wife of teh contractor team and maybe the landscape designer or an appropriate engineer or installer.

November 12, 2010 - LEED Platinum Home Progress Report

Contractor's Notes 11-8-10

Hello Everyone,

What to expect this week:

Monday- the guys completed almost all of the interior demo

Tuesday- they will complete the demo of the garage

Wednesday- they will build the foundation walls from the waste wood from the garage and interior

Thursday and Friday- more foundation work, they will be looking to pour early next week

We spoke to Cliff (plumber) who is getting his numbers together. We also spoke to another radiant floor contractor who can come out tomorrow afternoon to give an estimate. Then we will at least have a comparison.

The windows have been ordered and the exterior doors confirmed. The framing order will be placed at the end of the week.

Starting to Build - LEED Platinum Home Progress Report

Contractor's notes 11-1-10

Hello Everyone,

A rundown for this week:

M- build footings from recycled jobsite waste wood

T- footing inspection

W- footings

Th- pour footings

F- build foundation walls from recycled jobsite waste wood 

Would it be possible for you to contact the surveyor to come out on Friday to put a nail in the footings? We will be working on the foundation walls all next week.

We received the window quote and are verifying the information, we will place the deposit by Wednesday.

We have contacted 3 vermiculite remediation companies for the attic. We are waiting on estimates and will contact you when we have all three.

Elizabeth, the guys will be out on site all week. They have a couple of questions about elevations and the direction of the floor joists in reference to the new drawings. Would you be able to meet them on site to answer their questions? It should not take long. They take a break around 10:30 and then lunch at 12:30.

'Contractor's Notes' Begin - LEED Platinum Home Progress Report

The Contractors have started making Weekly Notes on Mondays so we will know what to expect of them in the coming week. I will copy them here throughout the Blog and then make commentary on them as appropriate and post it all on Friday of each week.

All notes are origianally written by Erin- the wife of the contractor team. (See the Cast of Characters entry to get the who's who)

Contractor's Notes 10-25-10

Hello Everyone,

What to expect this week:

Monday- both additions are down, back footing is being dug

Tuesday and Wednesday- side excavation and refuse removal

Thursday- demo

Friday- demo

Who is in charge of contacting the surveyor? We need him/her out on Thursday, so that we can construct footings and seek inspection the following week.

Also, what is the position on the radiant heat? If you are interested, we would need to know sooner rather than later because it does effect the elevations.

Breaking Ground - LEED Platinum Home Progress Report

October 18, 2010

BREAKING GROUND


Construction has begun.

Or I should say demolition. The team started demolition on October 11.  The deadline for construction is July 7, 2011. Nine months from contract signing.

So far they have started to take down the two one story ‘ells’ on the house. These are to be removed to make room for the new addition. They are proceeding with demolition very carefully and slowly. It is really rather amazing. Because of the dedication of these contractors to the cause of salvaging all they can from landfill and because of the reinforcement of that ideal from both LEED and the client, they are going all out.

They are meticulously removing each piece of siding and lathe from the house. They are removing nails by hand and stacking all of that wood neatly for reuse later. Some of the shingles will have to be tossed but much will be used for shims. All of the old lathe will be reused as the air spacers (furring strips) to go between the sheathing and the new siding. It is stockpiled in a clean dry place for later use. The lumber from the house is also salvaged and will be used whereever it can be for making concrete forms, as blocking, or any other place where it does not need to be pretty or perfect.         

 

LEED

What do I mean by energy efficiency vs. health. Well, experientially, as an architect who is heavily involved in the building of a house I pay attention to what is current practice in the world of building. (Some architects only ‘design’ - without too much concern for how a thing is constructed. I happen to be one of the ones who design with a very integrated approach- taking in all aspects of constructability and an awareness of structure and systems as we go.) I have been attending ‘green building conferences’ for 12 years. In all of those years I can easily say that the vast majority of papers given and discussions had have been about the energy efficiency of buildings. The envelope design, the mechanical systems, heat gain and loss, cooling loads, window technology, geothermal systems and solar, embodied energy in production and transportation, return on investments, etc.

Another aspect of green building is of course the sustainability factor. You can read about this in almost any magazine you pick up- it is everything from bamboo floors, no voc paints, locally sourced stone, fsc certified wood, water barrels, natural fiber carpets, etc etc. The public is more aware of these things because they are more interesting to talk about and easier to do. The public also is aware of things like cfl light bulbs and low flow shower heads, etc. These are all of the things people talk about at cocktail parties. The ‘u’ value of your wall assembly is not so easy to toss around.

Both energy efficiency and sustainability offer opportunities for improving the overall ‘health’ of a house and its occupants. The better a wall is built the less likely it will be to have mold and mildews. The more properly sized and integrated an HVAC system is the better the indoor air quality will be. No VOC paints and formaldehyde free millwork will limit air pollutants, getting rid of petroleum based products wherever possible (lie foams and vinyls) will not only greatly improve the health of the people who manufacture and install these products but it is proposed that is will also reduce the risk of asthma and other adverse effects in the long term occupants of a building.

So, many builders of production houses will build a VOC laden, foam insulated vinyl box that not only has very little aesthetic appeal but would also probably fail a lot of health tests. They usually put in a super high efficiency forced air system that turns the air over a lot and the comb of that with a really well insulated, well-sealed wall can go a long way in making up for that but it really ignores a lot of the deeper aspects of long term health for occupants. Our clients did not want their long term health to be ignored.

 

LEED

LEED addresses energy efficiency, sustainability and health in its point system. It could be said that even LEED leans toward energy efficiency and sustainability and leans less toward health but if you simply understand that if you build a house correctly, many health benefits will be integral in the house already you see that the health aspects are actually addressed. To truly make an optimally healthy house however you have to try harder. You have to figure out a way to build a very efficient wall without using foam for example. You have to work harder to find low VOC glues and adhesives. You have to think about indoor air quality when the power is out for a week. You have to think about every single thing that is going into the house. It’s a lot harder to make an efficient, sustainable house that is also very, very healthy.

LEED Points ~ Setting Goals - LEED Platinum Home Progress Report

We have a LEED construction planning kick off meeting with the team  (owners, architects, contractors, landscape architect and LEED provider.) We run the entire LEED for Homes requirements and points list and set goals for each one. It really does become clear through this process of reviewing the LEED point system, that the clients major concerns do lean toward healthy, clean, green living a bit mroe than they do towards energy efficiency- and as said before there is a high concern for energy efficiency, it's just that health concerns seem to be a bit higher still.

Bids Come In! - LEED Platinum Home Progress Report

September 24, 2010

Bids Come In!

We actually gave out bids 4 weeks ago and are getting numbers back now. 

(Go back to August for a refresher on who the contractors are!)

The bids come in and they are true to experience. Contractor D is the highest – by a lot. (This is a big, established Fairfield County builder of high end homes) Contractor D’s bid comes in just under $1Million. They are immediately crossed off the list.  Contractor C comes in at about $515,000. Contractors A and B (the 2 favored, green contractors) come in somewhere in the middle. Contractor A – the young husband and wife team come in at about $560,000. Contractor B- the brothers- come in at about $610,000. Contractor B also expresses some negativity at some of the details for insulating the basement and the shape of the house.

The basement is hard. It is a rock wall foundation. We are doing as much as we possibly can and I have a lot of experience with these basements and I have also consulted many experts – I can’t see a better way to approach the basement. I discuss this with Contractor B and tell him I am happy to make it work in whatever way we can and that he should let me know how he would do it better. He grumbles a bit and concedes but the overall vibe is that Contractor B is not that into doing this job. They also lean more toward energy efficiency and do not inspire a ton of confidence regarding health issues. This bothers the client a bit.  Because of these things and because the bid is about $50,000 higher than Contractor A- they are crossed off the list.

So it is down to Contractor A- the original favorite and Contractor C. Contractor C is also a very large company. They do a lot of commercial work but also have done some nice residential. They seem very straightforward, fast and down and dirty. They don’t know much about green building but they know some and they swear they will do whatever the clients want in that regard- they don’t care- whatever the client wants is what they will get. And we all kind of believe them. Their vibe is very ‘get it done’. They have a huge team and between the commercial and the residential they keep everyone working which is how they seem to keep prices low. They inspire a lot of confidence. None of us can believe it but they are seriously in the running.

We have a few more interviews and the more we meet and the more the clients think about it, the more they want to do the right thing. Contractor A has very strong values regarding sustainability and house health and really brings to the table the same level of intentionality that the clients and we, the architects, do. We all agree that Contractor A would sort of complete the team and we would all be on the same page in our efforts to build a healthy house with a low carbon footprint for the reasons of helping the earth and raising awareness about pollutants and waste and fossil fuel consumption. We all know intuitively that Contractor A is the right match even if they do cost about $45,000 more than the lowest bidder. Plus it is rarely a good idea to take the lowest bidder. The likely hood of change orders will be quite high.

So Contractor A is given the contract! Everyone is happy and excited to start! The choice feels exactly right.

 

LEED

Contractor A has not built a LEED home before but has done many very efficient homes and is excited to build a LEED home. 

LEED Registered Home- For Sure! - LEED Platinum Home Progress Report

 

September 17, 2010

LEED

Ok- we have building permit and the client has decided one thing for absolute sure:  We WILL pursue LEED certification. Now we have to hire a LEED provider. LEED providers are consultants who guide, regulate, enforce, observe, check and sign off on each of the LEED ‘features’ involved in the construction of this house, and thus the points we get within LEED.

These points are all cataloged and recorded in specific forms within the USGBC's LEED for Homes system. There have been a lot of jokes made and criticisms of the LEED points systems because in some cases it seems that you can get a lot of easy ‘low-hanging fruit’ points and not really do much to enhance a building environmentally speaking. Perhaps the best and most overplayed example of this is the ‘bike rack point’ in LEED commercial project construction.

While it may be true that there is some low hanging fruit, there are mostly a lot of other points to be achieved that are truly difficult and have a big impact on a project’s carbon footprint.  Basically the LEED provider will make sure that we are reaching these points and that it is all documented. Once we have hired one, we will meet as a team – owner, architects, contractors, sub-contractors, structural engineer, landscape designer, and civil engineers and review all of the possible points and set targets for what we think we can achieve. After that it will be a matter of making it happen. Some things will fall by the wayside because they are too hard to achieve or too expensive but we will make our best effort to meet as many points as we can. We all are shooting for LEED Platinum- the highest rating available.

For more information on the LEED for Homes rating system please go to the USGBC (United States Green Building Council) Website http://www.usgbc.org/DisplayPage.aspx?CMSPageID=147

 

Back to the Zoning Board! and What That Has To Do With LEED - LEED Platinum Home Progress Report

September 10, 2010

BACK TO THE ZONING BOARD

We have to go BACK before the zoning board again to get approval for changing the direction of the upper roof.

The clients have decided that they would like to pursue LEED certification and that they would also like to put solar panels on the roof.

The third floor roof is where the solar panels would have to go. The orientation of the third floor roof was talked about often in the spring and we were all well aware that the orientation would have to turn 90 degrees to get solar panels to work. BUT we had zoning issues and felt that the odds of the house getting approval would be higher with the roof oriented the same way as the existing second floor roof- it would give the house a bit of a lower profile in the front even though the heights of the roof would be the same either way.

So we prepare the drawings to go before the zoning board again. In the end we get approval to change the orientation of the third floor roof but the win is not without a lot of hassle and anxiety for everyone- never mind the highering again of a lawyer.

The town of Darien has a sort of strangely run zoning department and it is policed by a zoning official who seems to put his own opinion above the zoning ‘laws’ and above the qualifications of the zoning board itself.  It is unfathomable to all involved (in this project or any other) why the town, the town officials and the ZBA put up with this sort of behavior from one employee, but there it is. For now it is just this horrible experience that the tax payers of Darien have to deal with to get a house built. It costs tons of extra money in legal fees and keeps everyone involved up at night with worry. It really is a shame that they allow this behavior to run their department. It would never be allowed In any other town of which I know.

LEED

Also it seems strange from the LEED point of view. I serve on a few boards and committees in Fairfield County, CT. Boards or committees that focus on green building and the greening of municipalities.

Every town I know is trying hard to think of ways to incentivize energy efficient building. Other towns are bending over backwards to serve their constituents who choose to build green. They are giving them quick and easy routes through the permitting process, waiving permitting fees or giving local tax incentives. They are also ‘shouting about it’ - writing articles in the papers and high-lighting these projects on the town websites. We are building a house that will not only be LEED certified but will likely be off the charts Platinum LEED certified. We will get lots and lots of points for staying on a pre-developed small in-town lot, close to all amenities and utilities. We are building s VERY small house for Fairfield County (we are bringing it from 1800 square feet to 2700 square feet.)

To be treated this poorly by the town when we are really giving so much back to the town with this house just seems very wrong. 

How are we giving back with this house?

  • We are giving back by NOT tearing down an entire existing house and all the trees on a lot to clear the way for a mansion (either on this site or another).
  • We are giving back in the form of diverted, captured and re-used rain water, we are giving back with much smaller sewage loads in the form of super low flow and low flush plumbing fixtures – both lessen the load on the towns water and sewer systems.
  • We are giving back in the form of greatly reduced power load to the electric grid. Between the super-efficient lighting fixtures and appliances, the smart use of day-lighting and the application of a 3kW PV system, this house will likely use about 1/3 or 1/4 the electricity of a ‘normal’ house in this area. 
  • This is including the use of the electric based ‘Mini-split’ cooling system that will be installed. We are helping reduce the electric load of that incredibly efficient mini-split cooling system by providing a very well insulated house and using shading to regulate the summer sun.
  • We are giving back in the form of a natively planted garden that will require little if any extra irrigation. Planting native plants only helps reduce the infiltration of invasive species and re-balances the local ecology.
  • We are giving back in the form of a very low maintenance, long lasting home that will exist for a many, many years to come and require almost no paint job or major upkeep for at least 20 or more years – and then upkeep will be extremely minor. ‘Normal’ houses in our areas that are built with average construction and cedar shingles need to be chemically washed or sand-blasted and painted every 3-5 years or so. This act alone dumps a load of chemicals and pollutants into the local atmosphere and water table.
  • We are giving back by planting and landscaping with 90% native plants that are require little water, by providing porous natural landscaping and by using a smart irrigation system which will feed primarily from the collected rainwater that we have stored.
  • We are giving back in the form of supporting the homeowners lifestyle choice by enabling simple and clean green living activities like mass transportation commuting and/or walking, recycling, composting and healthy cleaning – all of which are enhanced by design layout, the provision of spaces for each of these things and the use of all natural, durable materials that reinforce such a lifestyle.
  • We are giving back in setting a strong example that people in Fairfield County can live very happily in a smaller house, close to town and close to all amenities in a way that greatly reduces this family’s carbon footprint. And we are doing all this with a lovely, classically designed small house that fits in perfectly with the historic and existing housing stock.

 

Imagine if every house built gave back in these ways.

Imagine the huge impact that would have in the reduction of resource use, fossil fuel use and the reduction of pollutants laden upon the local infrastructure. We live in an area where the power grid regularly shuts down in the summer do to use cooling use overload. We live in an area where the recycling centers and garbage dumps are overflowing with waste- often in the form barely used suburban ‘toys’ and electronics and half eaten meals- waste that would ever happen in a less wealthy environment.

Imagine the financial savings a town would notice if all the houses built in its jurisdiction were such low impact.

The town should be thanking this client and giving them an award, not harassing them for inexplicable and un-definable infractions on the selection of building trim.

 

Out to Bid! - LEED Platinum Home Progress Report

August 20, 2010

OUT TO BID!


Though the Zoning Board has been a huge distraction, drawings are ready to go out to bid.

We have 4 contractors bidding this job. Truly 2 of them are our focus (because they are the super green builders in our area) but we are all willing to be won over.

Let’s call the 4 contractors A,B,C and D.  A and B are the favorites.

Contractor A has known the clients for a few years. They are a husband and wife team in their early 30’s and they happen to also own a green building supply and green products retail store. The clients have been shopping there for years. It seems like a no brainer to go with this team but there are some minor hesitations- they are a small, young outfit. They are extremely honest and earnest but perhaps they do not have the super professional polish or the trusted established-ness of a bigger, older firm. Otherwise they are a shoe-in.

Contractor B are brothers in their 50’s, very established as the most experienced green builders in Fairfield County. They are also extremely honest and well intentioned. They have a great track record and are very trusted. The fears with them are that they may cost more and also that they may lean more toward energy efficiency and less toward ‘house-health’. This is a very big issue for the client. The green building world in general does lean heavily towards energy efficiency health usually takes a back seat. The clients care more about the health aspects of the house than the energy efficiency. They do care about both, but health needs to be primary.

Contractors C and D are ‘normal’ contractors. They are in the mix as a cost check. They are there to make the cost upgrades for going green a bit more transparent.

There is always the fear that a green contractor will be more expensive - partially because the work they do could come at a premium and partially  because they are more of a specialty contractor. My experience is the opposite. I have found that for the most part green builders – true green builders -  are a very honest and conscientious bunch and their prices are often way more fair and straight forward than many ‘normal’ contractors. Also if you are truly building green and know what you are doing there are many places to actually make the construction less expensive than normal construction. So I have never had the experience of a truly green contractor giving a high bid. Usually they are middle of the pack and that is correct because usually that is the actual price.

Yes, some green building features come at a premium, but then again so do some normal kitchen countertops and appliances,etc, etc. One of the favorite lines a contractor friend of mine uses when asked what the pay back time on that green 'insulation, solar panel, water collection system, green counter top, fill in the blank' is, is this: He simply responds 'What's the payback time on your 'granite counter top, giant HD TV, Maserati, SubZero wine fridge, second master bath because you can't share, fill in the blank'. : ) 

WHEN TO HIRE THE CONTRACTOR - LEED Platinum Home Progress Report

JUNE 18, 2010

WHEN TO HIRE THE CONTRACTOR:

LEED

Perhaps one of the best notions of building LEED is the idea of the team. Ideally the full team would be on board to ‘design’ the entire house. From floor plan to structural framing to exact wall assembly. In custom home construction this rarely happens. In custom home construction it is almost always the architect who designs the house to near final design, then the structural engineer is brought on board to engineer the house and then the house goes to bid and the general contractor and sub-contractors get to add their opinions which will be heeded or not. This is standard operating procedure and if you have a thoughtful, experienced and flexible architect it can work out fine. If you don’t then a lot of changes – to the drawings and overall concept or plan of the house may need to take place. This is especially true of green building and even more true of designing a home to be LEED certified.

Why don’t clients hire the contractor to be on the team from day one? Well some clients do and recognize the value of this (but it is rare). Most clients worry about money. They worry that they will get duped or ripped off in what some see as shadowy world of contracting. Say they choose a contractor from the beginning. If that contractor is not honest then the final bid might come in a lot higher than it would have if he knew he had to bid against other contractors. So there is always the fear in some clients that they could be saving 30 or 100 thousand dollars if they had bid the job instead of hired a certain contractor form the get go. And that really can and does happen so their fear are not without warrant.

I know that the two contractors we are considering are both extremely honest and straight forward. There contracts are quite ‘see through’ and the costs of their jobs are always very reasonable. They are not the lowest cost guys but they are far from the highest. They give solid reliable bids that are pretty much true to cost. But still, there is always that unknown. Even the way some contractor’s subs bid can make a difference of tens of thousands of dollars. And this is an honest difference. One guy might simply use a cheaper sub or have a slightly smaller fee for general management or get supplies from a less expensive supplier. This is normal and can make a huge difference in costs to the client. This is especially true in our area: Fairfield County CT. We have towns like Greenwich, New Canaan, Darien and Westport bordering small, poorer cities like Bridgeport or Norwalk or Danbury. All of these places are easily within driving distance for both supplies and labor. OR a contractor could simply go to one of the next counties- barely further away and drop his price by 10-20% or even more.

There is also the contractor factor itself. There are what I call pick-up truck contractors and there are what I call ‘Escalade’ contractors. In our county both are absolutely normal. The guys in pick-up trucks get their hands dirty, often don’t give the client much in the way of paper work and sometimes don’t speak English that well. These guys will usually get the job done pretty well but there will be a ‘suspension of disbelief’ required by the client at some points during the job- meaning the client is going to simply have to look the other way and have faith- it will get done. And it will. It will all be fine in the end but the client might get really nervous. The 'Escalade' contractor on the other hand has nicely manicured hands. He has all of the paperwork you could ever want ready at exactly the right moment. His crew is always on time in the morning and he often brings the client coffee to boot. These guys are good but their prices can easily be double the pick-up truck guys price! Why? Because they have so many layers of management that they have to pay for. And this guy has a life style to maintain. He probably goes to the same parties and is on the same library board as the clients he is working for. He lives down the street and his kids go to the same schools.  We work with the full range of contractor but our most common contractor is the ‘Toyota Camry' or the ‘Toyota Prius’ contractor. He is somewhere in between pick-up truck and Escalade. Either super green or just willing to learn.

The contractors that often know and do LEED are usually the Prius sort. They are truly well intentioned, smart guys who are doing the green thing for a reason. There prices are honest and accurate. There know-how is tried and true and there motivations are very sincere. If we are designing a truly green home- these are the guys we call. And unfortunately there are not a LOT of them.

We- as architects – want to work in a team for the green or LEED home. A team means all parties involved are putting their ideas and know how into the mix. This just makes the job happen more efficiently in both planning and construction, and makes a better finished product.

For example, I know a lot about designing super energy efficient wall assemblies but I always work with the contractor to finalize and refine the exact way we are going to build. A lot of architects don’t work this way and a lot of contractors don’t work this way. On many jobs there is simply the hand off from the architect to the contractor- a passing of drawings and the two never speak again. This to me is a shame. To me that is a huge loss of opportunity to refine the product and save the client a buck along the way.

Plus many architects don’t know anything about building green – just as many contractors don’t know anything about building green. There is often an education taking place on the job site. If a knowledgeable architect draws a ton of energy efficient details and the contractor doesn’t understand them and so does not build them- then they are worthless. If the architect does not know any energy efficient details and the contractor does and tries to incorporate them after the drawings are done this can result in huge wastes of time and money for the client during construction.

In the end I think green building  is really just quality building . Everything about LEED is just ensuring the client has a very well built, long lasting home. Some contractor do not build for quality- they build to make a buck. Some contractors don’t know any better and just build the way they were taught. This is all similarly true of architects. Some architects just build for beauty. Some architects don’t know any better and just design the way they were taught. Both need to evolve. Both will be required to evolve as building codes evolve to meet what is currently LEED standards.

Just one last note about LEED on this subject. It is not critical and some may deem minor. But to me it is important. When one looks at the LEED web site and searches houses that are certified LEED it lists the house, the location, the owner, the LEED provider and the CONTRACTOR. No where is the architect listed. For me- the architect who is very often training the contractor on site as we go how to build an energy efficient house-is imperative to building a custom home in an energy efficient, LEED way. The fact that architects are not listed is infuriating! I do all of the work- often the hard way- by cajoling and yelling and getting exasperated and spending way too much time and loosing way too much money teaching the contractor (and the client) how to do it right and that guy gets all the credit! I know the same can be true reverse. Contractor getting annoyed by the 'dumb architect' and trying to teach them a thing or two. But really the USGBC should be able to acknowledge either or both,

The more energy efficient the house will be, the more team work is required. I love this. The contractors I know who build green love this. We prefer to all be on the job from day one. If the whole team is on the same page and working toward the same goal, we all get a better product and not only do we all get a better product - we all get peace of mind as well as a joyful, interesting and stimulating work environment. A happy team, Architect, Contractor, Client.

CONSTRUCTION PLANNING - LEED Platinum Home Progress Report

March 12, 2010

CONSTRUCTION PLANNING

We have put a lot of thought into space planning for the house- to make it beautiful, practical, and energy efficient. Construction wise we also have a plan. The plan in general is to make the most well insulated, and well air-sealed envelope (basement, walls and roof) that we can. Then to use the most energy efficient heating, cooling and ventilation system that we can. To specify high efficiency windows, lights, appliances and plumbing fixtures and to use only sustainable, healthy, no-voc (or if we must low-voc) materials

We considered a number of wall assemblies that we are thinking of for the house. Often we will frame a house 24” on center instead of 16” on center- thus allowing for more insulation and less thermal bridging. But with this house so much of the existing 16” on center exterior wall framing and floor framing was going to remain and new structure needs to tie into the 16” on center, so it is more efficient -framing wise- to stick to the 16” and not go to 24” on center with the new parts.

The existing house is also 2x4 construction. New houses in our climate are generally built with 2x6 walls to allow for more insulation in the wall cavity. We will build the new exterior walls with 2x6 but we are stuck with the existing 2x4 shell where it occurs (about 1/4 of the final exterior wall area.) We would make these walls thicker to the inside but  there is literally no room in most cases as a large area of it borders the L shaped stair case which is pinned on its other side by a massive masonry fireplace and chimney.  The stair width barely meets code as it is. But we will thicken the walls to the inside anywhere we can.

We decide right off the bat to wrap the house in a continuous rigid insulation. This will help -significantly -to kill thermal bridging (the place where hot or cold can travel between interior and exterior through the studs in the envelope.) and it will also help make up for the 2x4 'thin' walls where they occur. This rigid foam insulation will add about R7 to the exterior of the house and act as a continuous air barrier as well (when the seams are taped).  

(It is sort of 'ironic' that we also cannot go out to far to the exterior- this rigid board insulation cannot be too thick- because we are already on the line for setbacks and coverage with the town and adding an extra inch or 2 around the perimeter of the house will truly anger the zoning board and stop the project. This is also so ridiculous! We are HEMMED IN! Yet another hindrance to building the right way.  Especially when we are doing the town a favor. We are saving the framing of the old house! That is not easy or cheap to do. Demo is easy and cheap! Saving stud walls when everything is gutted around them is not. We are saving recourses and retaining the existing footprint of much of the house. We are building a very small, very conservation oriented home! All of this will reduce impact on the town itself. One would think that the town elders would be happy to have us further reduce the carbon footprint of this house by allowing us another inch all the way around for better insulation. Sigh ~)

Next we need to choose an insulation. When faced with 2x4 wall cavities we usually choose a closed cell blow in foam. Basically the insulation options available are fiberglass batt (the pink stuff we mostly all have in our houses) fiberglass blow-in (a blown in version of the batt, better because it gets in nooks and crannies that batt cannot get into.) Blown-in cellulose- which is recycled newspaper, etc in a blown-in form – again better than batt because of the way it fills the cavity plus better for the earth. (There are actually 2 forms of cellulose- wet and dry. We never spec the wet, it has a history with too many problems with developing moisture problems in the walls). There is a denim batt insulation- thick blankets of recycled  blue-jeans. And lastly there are open and closed cell foams.  Closed cell foam has a higher R-value but also has a higher carbon footprint- basically it is not very good for the earth due to its production, its off-gassing during installation (and after) or… during a fire. Open cell foam has a smaller carbon footprint but also a lower R-value than the closed cell.  

We will leave this decision for now as the clients have a lot of things to think about regardign insulation and it gets quite complicated.

 

LEED

We have already got a landscape designer on board who is focused on LEED. We know that both contractors under consideration have either built LEED homes before or have built many super efficient green homes that could have been LEED certified. I am serving as the building envelope and construction efficiency expert until we hire the contractor at which point he and I will collaborate for exact technique and cost efficiency measures.

Ideally the contractor is hired in the design phase and travels through the entire design process with the client- architect team. Then the contractor – or the contractor and architect together- would serve as the building envelope and construction efficiency expert. Having designed and built one LEED home before and many other very efficient homes that could have been LEED certified before that, I have a lot of experience in designing a building envelope and nuancing construction efficiencies.  So it works to start without the contractor, it is just not ideal. When we hire a contractor we will meet with them and go through all the details. Fine tuning things here and there to make the contractor happy (some contractors just like to do things one way while another might do things another- the results being the equal. ) Or we may revise to save the owner money or making something work better. 2 heads are always better than one!

What does all of this mean and why does it matter? Basically to build and energy efficient home and to get LEED certification you need to build a home differently than ‘normal’. The walls of the house and the roof and basement (the building envelope) need to be highly insulated and also assembled in such a way to reduce air infiltration and thermal bridging (the ability of heat or cold to pass physically between materials) to as close to zero as possible. Wall assemblies, etc can get highly complicated, I have been attending green building trade conferences for 12 years and have watched the guys who have been doing this diligently for over 30 years still argue vehemently about how to do it best. The biggest dangers of a poorly thought through wall assembly being moisture control and the potential for mold, mildew etc. It is a given that any house built tight will need a method of ventilation and air exchange, but even with great air flow a house can still encounter moisture issues if the wall assembly is wrong. `
