The Zero Energy Modular Affordable Housing Initiative (ZE-MAHI) installed two zero energy homes in Florence, MA. Zero Energy Modular (ZEM) construction creates healthy, durable, factory-built homes. These homes can be both single family and mobile and manufactured home replacements. ZE-MAHI is a program of the Massachusetts Department of Energy Resources; through ZE-MAHI, ten ZEM homes will be installed across Massachusetts. The two Florence homes are the program's first installations. Construction was completed in September of 2019. ZE-MAHI provided program incentives to help offset the purchase price of the homes. Local utilities provided additional incentives. Pioneer Valley Habitat for Humanity acted at the developer for both homes, which are now owned and occupied by income-eligible families.
The homes feature ultra-efficient design and appliances (cold climate heat pumps, ventless dryers, advanced heating and ventilation systems) and rooftop PV sized to meet the modeled consumption of the homes.
