The LEED (Leadership in Energy and Environmental Design) Green Building Rating System™ is a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. LEED was created to:

  • Define "green building" by establishing a common standard of measurement.
  • Promote integrated, whole-building design practices.
  • Recognize environmental leadership in the building industry.
  • Stimulate green competition.
  • Raise consumer awareness of green building benefits.
  • Transform the building market.
Energy and atmosphere credit required the building to comply with ASHRAE/IESNA 90.1-1999 or local energy codes if it is equivalent to, or more stringent than, ASHRAE/IESNA 90.1-1999 standard.

By reducing design energy cost compared to the energy cost budget for energy system regulated by ASHRAE standard 90.1-1999. Building may earn up to 10 credit point when design energy cost reduced 60% of the design budget in the new building and 50% in the existing building.

Title 24 Calcs can deliver the following to your project team:

  • Establishing a Model energy calculation based on ASHRAE 90.1-1999 or local energy codes, we will provide a performance method calculation and computer modeled report.
  • Provide technical help in lighting, HVAC, and envelope requirement to achieve the maximum points.
