Bill Dunster Architects asked ech2o to be the services consultant on the refurbishment of a large four-storey house in North London that resulted in an 85% reduction in its overall carbon footprint. By working closely with the contractor, ech2o ensured that the low carbon solutions chosen by the client were integrated successfully into the services infrastructure. A wood pellet boiler will provide all the space heating load and the hot water heating load in the winter; solar thermal panels will provide all the hot water in the summer; photovoltaic panels and a roof mounted wind generator will provide over 50% of the electricity used by the occupants; a greywater recycling system, dual flush WCs, water efficient showers and taps and rainwater collection for the rooftop garden will reduce mains water consumption by 70%.
