Sustainability Report

Evermore retains and extends the existing bungalow rather than replacing it, reducing the demolition and new construction associated with a replacement building. This reflects the whole-life approach set out in RICS guidance, which considers embodied and operational carbon across the full lifespan of a building.

• Evermore is fully electric, with space heating and hot water provided by an air-source heat pump. Underfloor heating and wall-mounted heating panels form part of the system, while the house was insulated to exceed Building Regulations targets.
• The window and door package, supplied by okoHaus, combines VELFAC V200 Energy and V200 systems, with triple-glazed V200 Energy units achieving approximate U-values of 0.75–0.91 W/m²K.
• Project data gives a combined heating and hot-water load of 10.4 kWh/m²/year, based on 1,459 kWh per year across a 140-square-metre floor area.
• A large underground rainwater harvesting tank was installed beneath the garden patio, with annual water consumption reported as 42 cubic metres per occupant. 
• Provision has also been made for the future installation of photovoltaic panels.
