Methodologies used for determining the sustainability of residential Essay

Methodologies used for determining the sustainability of residential and commericial properties - Essay Example The criteria are the following: Management – provision of a home user guide concerning the operation and environmental performance of the home, a considerate constructors scheme, a commitment on construction site impacts and a security conscious design. For Civil Engineering design and projects, the United Kingdom industry uses the assessment and awards scheme CEEQUAL. Like the the Code for Sustainable Homes, the CEEQUAL also use a points-scoring assessment but instead of 9 criteria, CEEQUAL is made up of 200 exhaustive questions relating to environmental and social impacts of a project including resource usage, ecological impact, waste management, community relations, landscaping and even archaeology. Projects are graded as Pass (>25%), Good (>40%), Very Good (>60%) and Excellent (75%). A CEEQUAL assessment is undertaken by a CEEQUAL-trained project member whose evaluations are checked by a certified CEEQUAL verifier. As with all point-rating system, the assessment can be affected by biases thereby leading to inaccurate points assigned. For example, the criterion MATERIAL in the Code for Sustainable Homes calls for a range of 0.3 to 1.8 points for sourcing building materials responsibly. While there is a technical guidance manual to help the assessor, the points assigned can still be subjective. There is also the question of whether the items such as composting facilities and rain water collection will actually be used. The Code seems to check only for its presence as having a home-user guide seems to be enough to earn points and not its actual application. Essentially, the assessment methods provides no guarantee on the degree of sustainability that could occur. Department for Communities and Local Government, 2006.
