Future of Building’s Energy Efficient Design

Future of Building’s Energy Efficient Design

The first zero-net-energy building in the United States was erected at the beginning of this century. In California, this standard has penetrated the residential market, and every new home will have to produce as much energy as it consumes by 2020. A building in greater Los Angeles goes far beyond that and is expected to generate 185,000 kWh of extra electricity by the end of year one. The Net Zero Plus Electric Training Institute (NZP-ETI) is now modeling the future of energy-efficient building design.

This is possible because of a combination of energy-efficiency design elements and emerging clean energy technologies. The NZP-ETI employs energy-saving devices like:

  • 144,000 square feet of LED lighting
  • DC lighting capabilities
  • Advanced lighting, energy management, and mechanical control systems
  • Interactive dashboards with real-time building performance data
  • Exterior solar shading wall
  • High Solar Reflective Index (SRI) roofing
  • Electrochromatic glass
  • High-efficiency heating and cooling systems
  • High-performance insulation
  • Passive ventilation with large, efficient ceiling fans

These design elements are expected to reduce the building’s lighting, heating, and cooling operations enough to cut electrical consumption in half.

A 500 kW rooftop and parking shade structure PV solar array provide the structure’s electricity. Excess energy is fed into a utility scale battery array, which stores enough electricity to power the building of 144 days of partial energy use.Read more
