Portfolio of Buildings - plans
Future plans• Air or Ground Source Heat Pumps for Pool Heating• Expanding lighting retrofits to take advantage of SEP incentive cycle• HVAC - Roof top units such as catalyst – partnership with SPEED and
SCE• Sub-metering to ensure gains achieved remain• Increased solar PV presence on rooftops to complement energy
efficiency measures – requires another 423kW to be ZNE on electrical consumption
