Active systems

Active systems are devices that can be incorporated into the dwelling to either further reduce energy consumption, to supply renewable clean energy, and to recycle waste.

These include :

• Solar and wind powered systems.
• On site water re-use, ie. greywater and blackwater purification systems, to flush toilets, and to water plants.
• Compost Toilets (waterless)
• Rainwater tanks to collect and store water for re-use.
• Stormwater detention systems to reduce runoff.

Most of these systems are costly and take many years before the initial investment is paid off.
