Sapa Building Systems Ltd

- Part L in the context of reducing CO2 emissions - The specific regulations, what they mean and responsibility for compliance - Thermal performance and U-values relevant to work on existing dwellings - Solar gain, robust details and air permeability with regards to existing dwellings

This material is designed as the second of a series of of seminars that investigates Building Regulations Part L as it applies to windows, doors and curtain walling. The unit focuses solely on new build dwellings. This unit is seen as an alternative available to either sector specific practices or those wanting to cover the material in a modular form. The aim is to enhance the design process leading to best selection according to building design and performance needs - Part L in the context of reducing CO2 emissions - The specific regulations, what they mean and responsibility for compliance - Notional & limiting U-values - Solar control, regualtions and guidance - Air permeability in relation to products, installation and pressure barriers By exploring one aspect of the Part L in context of glazed fenetrastions we are able to simplify the details and allow greater time for discussion and response.

This material is designed as a thorough, unbiased review of Approved Documents for Part L 2010 of the Building Regulations as they pertain to windows doors and curtain walling. By using extracts from key documents the seminar guides specifiers and engineers through both limiting and notional U-values, solar gain and air permeability issues - Part L in the context of the environment - A review of the regulatory requirements applicable to windows, doors and curtain walling - Comparison of U-values for notional, reference and actual buildings - A highlight of Regulation 17D for consequential improvements - Solar gain, both regulatory and in practice - Air permeability and pressure barriers - Part L transitional arrangements

The seminar will look at: - The environmental aspect of building solar gain - Regulatory and political influences - Earth sciences of solar position and incoming gain - Computer animations showing influence of building orientation - How sun's annual changes influence sharing needs

This seminar will provide an overview of: - The principal safety considerations - Regulations and requirements influencing the selection of windows and curtain walling
