The solution With this in mind, Premier’s design team factored in cutting edge green features such as a communal rainwater harvesting tank and a grey water recycling system, which collects bath and shower water to treat and filter for toilet flushing, washing machine use or irrigation. The properties were also given water usage targets, incorporating dual flush toilets and mixer taps/showers and were provided with photovoltaic panels to supply solar power. Features such as triple glazed windows and doors were also incorporated, and low energy light fittings were used throughout.
