Extensive deep retrofit to Passivhaus principles (EnerPHit) to this Listed Lodge in Hove. A fabric first approach was applied to improve comfort and indoor air quality, reduce energy costs and carbon, and limit overheating. The main lodge benefited from cutting edge timber double glazed sliding sashes internal to the existing windows (secondary glazing) along with 400mm of woodfibre insulation and airtightness improvements to the loft and a whole house constant fresh air ventilation system with heat recovery (MVHR). The link, rotunda and basement were stripped back to the bare structure and the fabric upgraded to Passivhaus performance with 350mm of insulation to external walls, Passivhaus levels of air tightness with triple glazed fenestration with integrated blinds to limit overheating. A second MVHR ventilation system was also installed and both systems had a HEPA filter resulting in exceptional air quality and comfort.
