| Objectives | (BD2268) The objectives of the project are: 1. To provide expert and technical support to Building Regulations Division on Part L 2. To provide support to the users of the Regulations 3. To review the operation and impact of the new Part L 4. To achieve improved energy performance of the building fabric by having calculated U-values that more closely match actual performance 5. To assess the thermal performance of innovative insulation methods 6. To provide input to BSI and CEN standards development inline with government policies 7. To develop calculation methods to meet future needs of Part L in line with DETR requirements 8. To investigate the implications of introducing requirements to upgrade the energy performance of existing buildings. Summary of results: BRE investigated innovative insulation products in three categories, low emissivity foil products, organic insulation products and vacuum insulated panels and identified gaps in product standards available and information,on which to base thermal performance calculations. BRE also investigated the effects of workmanship on the actual performance of insulation systems and the impact on actual U-values for buildings. The report suggested how these impacts could be accounted for in thermal performance calculations and proposed a construction checklist to assist in determining more realistic as-built performance. The project started when the revision of Part L 2002 was at the latter stages of development and ensuredthe finalised documents L1 and L2 were consistent. The review of Part L 2002 operation was brought forward to allow for a further revision in 2005 as announced in the Energy White Paper. The review looked primarily at the application of the 2002 revision amongst building control, however it highlighted problems with compliance and interpretation. The information was carried forward to the revision of Part L and a dissemination strategy was put in place as part of a separate research contract.Attendance and chairing of standards committees covering thermal insulation products and standards ensured ODPM had an input into the development of the European and ISO Standards. The project made a key contribution to the development of Part L and is thus anticipated to have a significant impact on future design provisions for energy efficiency. | |
| Abstract | This project is required to meet DETR's objectives of addressing health and safety issues, including control and reduction of CO2 emissions, as described in Prospectus 2000 under the Environmental policy aim. The Priority Area and Theme relevant to this project are Codes & standards & Other building regulation issues. The primary focus of this project is to support through firm scientific understanding the review and implementation of Part L of the Building Regulations.Proposals for an extensive revision of Approved Document L were the subject of a public consultation during 2000, and they are currently in the process of being revised. This is the first of several stages envisaged for the revision of Part L over the next few years. The project follows on from the existing DETR/BRE framework contract CI 36/8/79 (cc 1637). It is concerned principally on aspects related to dwellings, while covering issues concerned with fabric transmission (U-values and relatedtopics) forall buildings. It is closely linked to the parallel proposal CI 36/8/305 'Energy Efficiency in Non-Domestic Buildings' whose primary focus is non-domestic buildings but which includes topics concerned with lighting and air infiltration for dwellings. | |
