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
