Winners of Fifth Annual CT Zero Energy Challenge Announced

Posted: Mar 27, 2015

NEW BRITAIN, Conn. (February 24, 2015) – Energize Connecticut with its utility partners, Eversource Energy and the United Illuminating Company, have named three winners of the fifth annual Connecticut Zero Energy Challenge (ZEC), a statewide design/build competition for single and multi-family homes. This year’s competition featured 11 homes from across the state built between June 1, 2013 and December 31, 2014.

Participants are challenged to construct high efficiency homes that consume little to no energy and the winners are awarded cash prizes. ZEC homes are the pinnacle of high performance homes and demonstrate to the building community, as well as to anyone considering building a home in Connecticut, that zero energy construction is achievable.  

RESNET Rating Standards are used to determine each home's HERS Index (Home Energy Rating Score), a nationally-recognized scoring system for measuring a home’s energy performance (the lower the number, the more energy efficient the home; a score of zero represents a net zero energy home).

“The Zero Energy Challenge is a great opportunity for builders to showcase the innovative building techniques and new technology they are using to build a net zero energy home,” said Bill Dornbos of ENE (Environment Northeast) and Chairperson, Connecticut Energy Efficiency Board. “Building a zero energy home is becoming a more common practice, and the challenge also demonstrates that any homeowner can do it. Whether building a large or small home, building one that is net zero energy is a realistic option that delivers many benefits for years to come.”

Competing builders and architects implement energy-saving features into the home’s design to increase energy performance and lower its HERS Index. The project’s cost effectiveness and the home's total estimated operating costs are also used to determine the winners in each category.

This year’s Zero Energy Challenge winners include:

1st Place: Benker Residence, Glastonbury, CT
Homeowner: Carl Benker
Designer/Builder: Glastonbury Housesmith LLC, Glastonbury CT
Winning Categories: Lowest Overall HERS Index, Lowest HERS Index without Renewables (tied), Lowest Projected Annual Net Operating Cost
$25,000 prize

“It was important to us to build a home that was both durable and energy-efficient. By doing so, we will not only save money in the long run, but also achieve a lower overall environmental impact. We followed the most current building science construction principles, and the house will use no fossil fuels anywhere. The builder, Glastonbury Housesmith, made the house a huge success in our eyes.”  - Homeowner Carl Benker
