A new low energy house in the Edwardian suburbs of Cambridge. Having been occupied for a year, the energy readings provisionally suggest that its performance achieves Passivhaus standards of overall energy usage and the home uses a heat pump to deliver the very small amount of energy required. The ground source heat pump (GSHP) was a specification change from the gas boiler during the construction period, a decision prompted by a momentary leap in gas prices.
