Progress Report

Achieved 83% energy efficiency
Achieved 80% water efficiency

Special features

Net-Zero Energy:

  • EU I (Energy Use Index) rating of 10kbtu/sf/yr
  • A 242kW photovoltaic array produced 60% more energy than the building used in 2014
  • Geo-exchange system harvests energy from the earth to provide efficient heating and cooling
  • Radiant floor heating and cooling system
  • Through PAE’s in-house research, the building “plug loads” are expected to be reduced 78% through the use of cloud-based servers, thin client work stations, and laptops replacing desktop computing equipment

Net-Zero Water:

  • 56,000-gallon cistern for rainwater harvesting
  • Greywater reclamation
  • Composting, foam-flush toilets that save 96% more water
  • Rainwater filtration for potable uses (pending city permit)
  • Green roof and constructed wetland
