 1925 Colonial Renovation Earns LEED Platinum Certification in Darien, Ct.

 LEED Platinum Darien Ct


Usually LEED certified homes are new built but not this 1925 Colonial home in Darien, Connecticut that sits on 1/7 in town acre property (6,222 sq. ft. lot) originally with 1476 square feet of living space. The advantage of this in town lot is that you can walk to the park, downtown and train station.

The finished renovation gives the home 2858 square feet and achieved a HERS rating of 37/100. A Home Energy Rating System, HERS is based on performance of the home compared to a new home built to the latest energy standards. A new home if built correctly will have a HERS Index score of 100 while a typical resale home averages 130, the lower the score the more efficient the home is.

 The renovation resulted in a 67% decrease oil/propane cost per square foot adjusted for Heating Degree Days from $0.86 down to $0.29 per square foot while the electrical consumption decreased by 57%.  The insulation used in this home is recycled denim, which can be reused and is completely biodegradable.

Many of the interior features are made out of recycled materials, such as the window treatments, light fixtures and the counter top in the laundry room.

Underneath the exterior siding is a rain screen system which will help the paint to last 10 or more years longer than on a standard home.

In building a LEED home one sometimes needs to think outside of the box, before construction started there was a huge Spruce tree leaning dangerously over the original home. The tree was cut down and milled for the majority of interior trim of the new home.

The LEED home is designed to:-

  • Significantly reduce energy consumption
  • Create a healthier indoor environment, air and water.
  • Requires less maintenance compared to conventionally built homes
  • Re-use materials; use recycled and sustainable materials and products
  • Landscaping is designed with native and native like plants that require less to no additional watering, fertilizer and pesticides.

What an impressive remodel this home has had. To have such accurate facts supporting what green means makes this a very good post. The one question I did have is how much was the remodel cost for going green over conventional. Would make a great pay pack stat. cheers cvc

Curtis, I do not have the exact sq foot price but renovations usually cost more than new build due to the difficulty of working with what you have. I did speak to the builder a while back and he said approximately $350 sq ft which is not bad for our area. New built quality here can range from $235 up to $400 and $500 sq. ft on the norm.

David I am not familiar with the terms LEED and HERS, so this blog is a start to educating me on what they are.

Thank you for the info. Yountville has one new Leed's project here of 12 SFR. I am not certain what level they are but probably the lowest. I asked a builder who does a lot of development about how much more these will cost over building the homes just to current codes. He felt only a few percent more, 2-3. If this is true, it is almost idiotic not to in today's world with more and more energy conscious consumers. cheer cvc

Curtis, that is correct, is the builder is a quality builder then their home would almost certainly qualify for the basic LEED Certification and then to get silver and gold would be 2 to 5 % more approximately.

I specifically found this blog while looking for info on other leed and HERS homes, and this is really impressive. What a gem! I wish I lived close enough to see it.
