Minimum standards Categories Flexibility Energy Efficiency 6 levels of minimum standards; one for each level of the Code Water Efficiency Three levels of minimum standards, each covering two levels of the Code Materials A single basic standard at Code entry level Surface Water Run Off Waste Pollution Health and Well-Being Management Ecology No minimum standards
Minimum performance standards for Energy/CO 2 Code Level Energy Performance Equivalent rating Level 1 10% improvement EST Good practice Level 2 18% improvement Level 3 25% improvement EST Best practice Level 4 44% improvement Approx. Passiv. Haus / EST exemplary Level 5 100% improvement Level 6 Full Zero Carbon

What the ‘Code for Sustainable Homes’ means to you • • • ‘Goes Live’ from 10 th April 2007 Voluntary EP+HC = Communities England Planning Conditions 10% renewables v code levels
Mandatory Assessments ? • Under consideration by ministers • Introduction in the future • Requirement to carry out assessment and display • No specific performance requirements
Why Mandatory Assessments ? • You might already be above Level 1 • You might be very close • You might want to go to Level 1 (Do you want to display ‘no stars’)
Assessment A two-stage process • Design Stage • Post Construction Review • Approved Code Assessors
Customer Awareness • Does the public - Know - Understand - Care - Want it
What next • • Code seminars - CLG/HBF Code for buildings other than dwellings Existing housing stock The road to Zero Carbon 2016
