This month, Modular builder Keiser Homes and architecture firm Kaplan Thompson Architects launched the net zero energy series of modular homes called the "Modular Zero Collection."  These homes have been designed to use the smallest amount of energy possible and, if purchasers opt for solar hot water and solar photovoltaics, can produce as much energy as is consumed on an annual basis. 


Kaplan Thompson went through five wall assemblies before settling on the one rendered above.  The homes will have a cellulose double-stud wall system with R40 walls and an R60 roof.  The higher cost of insulation will be offset with a smaller, less expensive heating system.  

These energy-efficient homes will also have triple-glazed windows, airtight construction, long-life roof and siding, efficient ventilation, low-flow fixtures, low-VOC paints, and passive solar heating and cooling. 

The team has three designs shown below — Chebeague, Peaks, and Great Diamond — that start at $205,000, not counting land, utilities, and solar systems.  First units will be sent to Peaks Island in Maine, while Keiser Homes can ship throughout New England. 

960 square feet, 2 bedrooms, 2 bathrooms (from $205,000)


1,200 square feet, 2 bedrooms, 2 bathrooms (from $205,000)

1,680 square feet, 3 bedrooms, 2.5 bathrooms (from $235,000)
