Net Zero

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.
