Central Systems

To reduce the energy used by central systems in multi-dwelling developments:

• choose an efficient central hot water system;
• choose an efficient central cooling system;
• choose an efficient central heating system;
• install a central alternative energy source to offset some or all of the energy demand;
• choose suitable and efficient lifts;
• choose efficient pool and spa heating systems;
• operate pools and spas (especially pumps) efficiently;
• choose efficient sauna heating systems and operate them efficiently;
• install a Building Management System; and
• install active power factor correction.

Additionally, for common areas in multi-dwelling developments:

• provide common clothes drying lines if individual ones are not provided;
• provide efficient common clothes drying facilities that use an energy source with low greenhouse-gas intensity; and
• provide energy and water efficient common clothes washing facilities.
