Zero Emissions Ready Home (ZER)
Definition:
A Zero Emissions Ready (ZER) Home is a residence designed and constructed to achieve high energy efficiency, eliminate on-site carbon emissions from energy use, and be fully powered by clean, renewable energy sources. These homes are built to rigorous standards that ensure minimal energy consumption and are equipped to integrate renewable energy systems, such as solar panels, either during construction or in the future. The U.S. Department of Energy (DOE) defines a zero emissions building as one that is energy-efficient, free of on-site emissions from energy use, and powered solely by clean energy.
Short Description:
Zero Emissions Ready Homes are highly energy-efficient residences designed to operate without on-site carbon emissions, utilizing clean energy sources for all their energy needs.
The Zero Emissions Home program is for newly constructed homes (although it may be available for existing homes when doing a gut rehab). The program evolves as building practices improve.
All Zero Emissions Ready homes must meet ENERGY STAR Certified Home requirements, as well as Indoor airPLUS requirements.
Why It’s Important:
•Environmental Impact: ZER Homes significantly reduce greenhouse gas emissions by eliminating on-site fossil fuel use, contributing to climate change mitigation.
•Energy Efficiency: These homes are constructed with advanced building techniques and materials that minimize energy consumption, leading to lower utility bills and reduced strain on energy resources.
•Future-Proofing: By being ready for the integration of renewable energy systems, ZER Homes offer homeowners flexibility to adopt clean energy solutions as they become more accessible and affordable.
Other Things to Consider:
•When the home earned the label: Not all Zero Emission Ready Homes are the same. A home built to Version 1 standards is different than a home built to Version 2 standards.
•The label is binary: Zero Emission Ready Homes must meet a threshold to earn the label. One home may barely pass that threshold, while another home may have far exceeded that threshold. Looking into the HERS rating or other characteristics of the home is also informative.
•Design and Construction Standards: Achieving Zero Emissions Ready status involves meticulous planning and adherence to stringent building codes that prioritize airtight construction, superior insulation, and high-performance windows and doors.
•Renewable Energy Integration: While ZER Homes are designed to be ready for renewable energy installations, the actual implementation may depend on factors such as geographic location, availability of resources, and financial considerations.
•Certification and Verification: Homeowners and builders should seek certification from recognized programs to ensure that the home meets all necessary criteria for energy efficiency and emissions reduction.
Investing in a Zero Emissions Ready Home not only promotes environmental sustainability but also offers long-term economic benefits through energy savings and potential increases in property value.
