Project Description

Thornhill Roadlogo_enerphit_en

Derby

Thornhill Road is an EnerPHit certified retrofit of a 1950’s detached house. Project measures included a new PIR insulated ground floor slab, EPS external wall insulation and render, mineral wool pitched roof insulation, PIR flat roof insulation and a green roof to the garage, triple glazing, Mechanical Ventilation with Heat Recovery, low water use appliances and sanitary ware and photovoltaics.

The project was carried out by clients, architects and builders with no prior knowledge of Passivhaus techniques and building. At Eco Design Consultants we supported the team by applying our knowledge and experience of Passivhaus principles to project. The final result of airtightness at 0.32ACH and 23kWh annual heating demand demonstrate that, with care, novice teams can achieve great retrofit results.
