Code for sustainable buildings outlineBACKGROUND
The Code for Sustainable Buildings (CSB) is an evolving voluntary scheme being developed by Government and Industry. The aim of the CSB is the active promotion of more sustainable building practices. Click Here to Download Code SB PDF OBJECTIVETo develop a cost effective, practicable and marketable CSB which will become the single national standard for sustainable building that all sectors of the building industry will subscribe to and consumers demand. SCOPEThe CSB will apply to all new building developments; with the initial focus on new build housing. In the longer term it may apply to major refurbishment of existing buildings. The CSB will extend beyond the construction phase and set requirements for building performance. The CSB will focus on required outcomes/outputs and will not be prescriptive. It will also consist of a series of performance levels; each will have clearly specified requirements. There will be minimum threshold requirements for energy, water, waste and materials efficiency.
GUIDING PRINCIPLES
INITIAL OUTLINE OF THE CSBThe CSB will initially focus on the building itself (process and performance) and on associated aspects of the development. In the longer term it may consider specific aspects of the development such as site infrastructure and services and site layout and design. The CSB will set out clearly specified minimum performance requirements for energy, water and resource efficiency. It will also establish a series of performance levels; each will have clearly specified requirements. In establishing these requirements all the principles of sustainable development will be taken into account. The above requirements are performance based and not prescriptive. So designers, developers, builders and consumers have the flexibility and choice about how to design and construct a CSB compliant building. This will encourage innovation.
TIMINGSApril 2008 Mandatory Assessment of all new homes Proposed Changes to Building Regulations by 2008 transferring water efficiency related parts of current water regs into building regulations. & transfer of enforcement from water companies to building control officers. Aim to meet Code for Sustainable Homes Level 3 by 2010 Aim to meet Code for Sustainable Homes Level 4 by 2013 Aim to meet Code for Sustainable Homes Level 6 Zero Carbon by 2016.
The following categories will be included: ENERGY PERFORMANCE REQUIREMENTS
Buildings built to the Building Regulations 2006 will have an energy cost factor of ‘x’, / a SAP 2005 rating of ‘y’ and target carbon dioxide emission rating of ‘z’. Indicative CSB requirements – expressed as an energy cost WATER PERFORMANCE REQUIREMENTS
Average daily water consumption is approximately 150 litres per person. One option is to establish a SAP equivalent for water and express in similar terms to energy performance. Indicative CSB requirement - express as a percentage saving in terms of net metered supplied.
WASTE and MATERIALS REQUIREMENTS
Waste Management during Construction
The objective is to reduce to zero the amount of construction waste sent to landfill - CSB requirements expressed as minimising amount of construction waste to landfill. Waste Management during Occupation of the BuildingProvide adequate collection facilities in each unit for recyclable materials collected by the statutory body. Use of Materials
SERVICEABILITY REQUIREMENTS
Durability and Flexibility
Health and Well Being
Flood Resilience Measures (where appropriate)
