The term “Net Zero” applies to a building with zero net energy consumption and zero carbon emissions annually. Zero energy buildings are independent from the energy grid supply. Energy is produced on-site. Since buildings use 40% of the total energy in the U.S. and Europe, this design principle is gaining considerable interest as renewable energy as a means to cut greenhouse gas emissions.
Advantages of Net Zero building:
- Isolation from future energy price increases
- Increased comfort from more uniform temperatures
- Reduced cost of ownership due to improved energy efficiency
- Reduced monthly cost of living
- Additional costs is reduced for new construction versus retrofitting an existing home
- Higher resale value as future owners demand more Net Zero homes than are available.
- Subsidies may be available for homeowners building Net Zero homes
Challenges of Net Zero building:
- Initial costs of construction can be higher
- Only a few designers or builders have the skills or experience to build a Net Zero home (SBDI is experienced in Net Zero home building).
- Most appraisers do not consider energy in assessing the value of a building. This can pose a challenge to recover higher initial costs on resale of the home.
- Solar energy capture must have unobstructed access to the sun from the south. This can be challenging for some locations.
