Project Description

The design and construction of two environmentally friendly homes, in Canley, Coventry.  This particularly scheme was lead by FORCE, the Forum for Constructinge Excellence in Coventry and Warwickshire, heavily supported and guided by our Office.

‘In June 2009, FORCE asked industry leaders to help them to clarify what would constitute an ‘energy efficient’ home.  The responses were several and varied, but none offer direct guidance, at grass roots level. FORCE therefore decided to lead by example, and began to design and construct an exemplar home in Coventry, to demonstrate energy efficient construction and use.' (Extract from Presentation given to FORCE by Dhiran Vagdia, 24’th June 2010).

FORCE began building relationships and establishing partnerships, which, in the latter part of 2010, meant that the scheme had become defined, established and funded, in-part, by Orbit Heart of England Housing Association.

Project partners then moved on to include FORCE (Forum for Constructing Excellence), Orbit Heart of England Housing Group, the Homes and Communities Agency, Coventry and Warwickshire Chamber of Commerce, Coventry University and Coventry City Council.

The scheme proposal includes the construction of two detached houses, one to the Code 6 standard of the Code for Sustainable Homes, and one to the German Passiv Haus standard.

The Code for Sustainable Homes (CSH) is an environmental assessment method for rating and certifying the performance of new homes.  The CSH covers nine categories of sustainable design; Energy and CO2 emissions, Water, Materials, Surface Water Run-off, Waste, Pollution, Health and Wellbeing , Management and Ecology.

In contrast, Passive Haus is an energy performance standard, ensuring that the house has an excellent thermal performance, exceptional air-tightness, and is ventilated with efficient mechanical ventilation. This project aims to help the sub-region’s construction sector understand the technical, economical and practical challenges faced in developing a better approach to home building in this country. Parallel outcomes of this project include stimulation and development of the sub-region’s green technologies sector, increasing public awareness, and ensuring best practice.
