The implementation of Regulations for improved Energy Performance in Buildings throughout Europe has brought with it the need to provide high levels of thermal insulation and to minimise ‘thermal bridging’ that affects the practical use of all forms of construction. This is particularly relevant to the steel technologies used in housing and residential buildings, commercial and industrial buildings because of the risk that the steel elements add proportionately to thermal bridging in highly insulated building envelopes.
In many countries, it is planned to prepare the equivalent of accredited construction details for common applications that are used to gain Building Regulation approval at the early stages in the building design process. Many constructional systems also involve mixed materials and so it is necessary to consider thermal bridging parameters for materials in combination. Also, there is need to develop thermally-broken steel components that greatly reduce thermal bridging, but have good structural performance characteristics.
This process is complex because of the potentially large number of design cases and details that should be considered in modern steel construction. This proposal will address local details that affect the thermal performance and ‘thermal bridging’ parameters at key locations in the building envelope. This will extend to implications for air-tightness etc in energy efficient design solutions.
