Listed building Passivhaus design


greentomatoenergy was engaged by the client to design the retrofit of this penthouse flat of this listed building to EnerPHit standards for comfort and environmental reasons. The client requested to use materials that are as sustainable as possible and as space is at a premium, the property is insulated using Aerogel blankets. Outside space will be used for a solar PV system which will generate a significant proportion of the occupant’s electricity consumption. As the panels will be kept flat, their installation was approved on a listed building.
