Modular Zero

The Modular Zero Homes (MZH) line of homes was designed by Kaplan Thompson Architects in close collaboration with Keiser Homes.  The result of this partnership is a remarkable series of structures that through thoughtful design, extensive insulation, and intelligent choices of mechanical systems, generate their own renewable energy to heat, cool and power themselves – a concept referred to as “Net Zero.”

To achieve net zero performance, the homes have 12” exterior walls, with off-set 2×4 studs, 16” on-center.  When insulated with dense-pack cellulose, this provides an R-40 wall, with minimal thermal breaks. The windows are designed to provide for exemplary insulating capability, while the south facing windows are chosen to allow for passive thermal gain.  A solar thermal hot water system and photovoltaic solar panels are set on the roof, providing hot water and electricity, for both heating and powering the home.  Due to the extraordinary insulation, the minimal heat required to warm the home, even during the coldest Maine winters, allows for the use of a mini-split forced air heat system, which will also provides air conditioning during the summer months.

Every aspect of these homes has been designed to provide the highest level of comfort, at the same time allowing owners to benefit from today’s technology to secure a clean, budget-friendly energy future.  The close collaboration by Kaplan Thompson and Keiser results in the most affordable and livable net zero homes available.

Maine’s first Net Zero community is Brackett Estates in Wells, Maine.
