NuPlanet Director Ben is undertaking an extension and deep retrofit of his semi-detached, bungalow in Brighton. The property was originally constructed in 1937 and has been extended backwards, sideways, and upwards to increase usable space.
The building has been wrapped in 120-150mm insulation to minimise running costs, maximise thermal comfort and reduce carbon emissions while retaining the existing character of the property and street.
Heating and hot water demands will be met by a 3.5kW air source heat pump whilst an MVHR will provide filtered and tempered fresh air throughout. The goal is to achieve the EnerPHit standard via the component method and reduce bills to a minimum.
*This equates to a heat demand of 1 kw per hour on the coldest day of the year.
