Energy and Atmosphere High-efficiency cooling (30% beyond code) High-efficiency heating (10% beyond code) Six ERVs Low lighting power densities No chlorine in new cooling systems Management may purchase green power
Materials and Resources Reused over 75% of existing shell Recycled 75% of construction waste Used materials with high recycled content Over 20% manufactured locally Over 10% mined/harvested locally
