How Propane Homes can be Zero Energy Ready

Build with Propane, News: By Hallie Busta    April 20, 2018

Chris Trolle was interviewed for an article in the Build with Propane website’s news article section about a Zero Energy Ready Home and LEED Platinum project BPC built in Fairfield, Connecticut in 2012. The home uses propane as part of the home’s energy mix.  This home earned a HERS score of 39 when it was built. By adding a small 9kW PV solar panel array to the home, the home’s HERS score would be 2. Adding a slightly larger solar panel array would make the home a Net Zero Energy home.

Chris is quoted in the article:

“With each of the [ZNE and ZER] homes we do, we focus on a very robust thermal envelope,” Trolle says. “The fuel the client chooses to use is based on their budget and local availability.” Propane is a cleaner alternative to fuel oil and can be used nearly anywhere, including beyond the natural gas grid. Trolle says propane is generally used in these homes for domestic water heating, direct-vent fireplaces, and cooking ranges.

Ridgefield “net-zero” house powered fully by the sun

NewsTimes, Feburary 23, 2017

The article starts out with: “After nearly a year in their new home, the Ranades haven’t had to pay a nickel for the energy needed to run it.” It also says: “They turned to Mike Trolle, a principal at BPC Green Builders, and learned that it made more financial sense to completely rebuild, adding the energy-efficient features they wanted. ‘Generally, with the way the energy costs are going up in Connecticut especially, and the costs to build a green home have gone down, it made sense,’ said Kishore Ranade.”

Modern Breed

Ridgefield Magazine, November/December 2015

“A house is not just what you want but what the site wants,” says architect Vincent Colangelo. That’s particularly true for the modern house he designed off Branchville Road. Finished in 2010, this stunning contemporary sits on a 2.65-acre property that slopes down to the woods. Designed in collaboration with the owners and Wilton-based builder Mike Trolle, the house models comfort and sustainability. It is also a happy haven for the owners’ two retired greyhounds, Ender and Jolie. (…)

2014 Housing Innovation Award Winner: BPC Green Builders

U.S. Department of Energy Challenge Home Case Study

“Snow is cold, rain is wet, Chills my soul right to the marrow I won’t be happy … Till I’m home again and feeling right.”

Carole King penned these lyrics long before the 1950s bungalow on the street named after her in Danbury, Connecticut, was rebuilt as an ultra-energy-efficient home, but the words sum up how the homeowners feel about their new home, a lakefront cottage that has received a Zero Energy Ready Home certification from the U.S. Department of Energy’s Building America program.

Houses The Green Built

By Karen Sackowitz
Green Home 2014 Annual Issue

Despite the runaway use of the term in just about every industry, when it comes to quality home construction, it isn’t easy being “green.” What should be a well-quantified distinction has become a marketing term, shortchanging homeowners who want to know how the real process works and how to best ensure the life of their new or existing house. “everybody in the building community will say they are green builders, but it’s a sophisticated science and a complicated process if you do it right,” says Mike trolle of BpC Green Build
ers. “it’s also fascinating. As a builder, you need to keep educating yourself.”

U.S. Department of Energy Challenge Home Case Study

A difficult decision to tear down a 60-year old lakeside bungalow led to the construction of a Challenge Home-certified, LEED platinum home that takes energy efficiency to new heights in New Fairfield, Connecticut. Owners James Gainfort and Hayden McKay learned the old home’s concrete block walls would not support the second-story addition, they hoped to add to take advantage of views of Candlewood Lake and to increase storage space in this escape-from-New York weekend retreat that will one day be their year-round retirement home. So the husband and wife architects decided to make the most of the situation, tearing down the old, asbestos-tiled building to the foundation slab, salvaging everything possible, and designing a new, modern two-story home that captures commanding views, lots of daylight, and significant energy savings.

Low-Impact Luxury

GreenBuilder, June 2013

Nate and Etta Kantor wanted to live in a truly green home. To achieve their goals, the couple wanted to work with a contractor who shared their vision of green living and energy efficiency, their concern for the environment, and their rigorous attention to detail as they undertook a major renovation to their 5,000-square-foot Adirondack style cabin. They turned to Chris and Mike Trolle of BPC Green Builders to build the home, which was designed by architect Jim Edgcomb.

Healthy Homeowners

By Dan Briody
Green Home 2012 Annual Issue

Etta Kantor still remembers the reaction she got from her builder when she described the type of house she wanted him to build. “He was so excited,” she recalls. “He said ‘Oh, you want to pull out all the stops!'”

For most builders, it is the size and cost of a new project that elicits this type of reaction. But for Mike Trolle, founder of BPC Green Builders, the thrill came instead from the opportunity to put all of his knowledge and years of training in building science to work on a single project.

Scientific Method

By Dan Briody
Green Home 2011 Annual Issue

Mike Trolle knows things about houses that very few people know. He knows how much heat a flat-screen television throws off. He knows how much heat the toilet flushes of a family of four will suck out of the air. He knows the insulating properties of every conceivable material you might use to build and insulate the walls of your house. In short, Trolle, the founder of BPC Green Builders, knows the modern science of building. And along with his brother Chris, he is building some of the most energy efficient homes ever seen in this part of the world, including the only two LEED-certified Platinum homes in Fairfield County.

The High Performance House

By Jennifer Huget
Connecticut Magazine, May 2003

When you go shopping for a builder, you don’t expect to end up talking philosophy. But if Mike Trolle is the builder at hand, you’re likely to spend as much time discussing the principles that guide his work as you are counting closets and square footage. Maybe more.

By Christine Shugrue
Sierra Club Quinnehtukqut, Summer 2000

When it comes to improving our health we will consider changing our diet, exercising more, taking vitamins and slowing down a hectic schedule. Few of us, however, realize that our health can be seriously harmed by poor indoor air quality. Indoor air pollution, which may be tenfold higher than outdoor levels, contributes to a host of increasingly common ailments such as asthma and chronic sinusitis.

A Roxbury House that Helps You Breathe

By Kathryn Boughton
The Litchfield County Times, Friday, May 26, 2000
Business and Real Estate Section

In colonial America, settlers closed their houses tightly against the night air, convinced that unhealthy ‘humors’ were carried on the evening breeze. Today, the situation is reversed, according to Michael Trolle, a general contractor currently completing Connecticut’s first “Health House’ on the wooded Transylvania Road in Roxbury.
