Zero Energy Modular (ZEM) construction creates healthy, durable homes that generate as much energy as they use annually. With ultra-efficient construction and solar PV, ZEM homes offer low combined mortgage and energy bills now—and into the future.
ZEM Affordable Housing Initiative is supported in part by a grant from the Massachusetts Department of Energy Resources. The initiative provides the following support for home buyers:
- Ensure that home buyers receive all available incentives to bring down the cost of the home, including securing a grant.
- Help buyers find a lot for their home by actively recruiting resident-owned communities.
- Support the design and installation of the home before and after move in.
- Assist buyers in finding a mortgage lender.
