It is referenced in ADL as a 'second tier’ document as a way of showing compliance with the Building Regulations. It gives practical guidance on determining the U values of non-traditional building envelopes for input to a building energy model. Foreword This document is intended for use by the bui8lding design team, building envelope designers and building inspectors. It allows the early estimation of building envelope U values, details the information required in a specification and describes methods for showing compliance of the final building envelope design with the requirements of parts L2A and L2B of the Building Regulations. The appendices show how detailed calculations should be undertaken to establish component U values and the properties of their associated thermal bridges and how these should be incorporated into a detailed calculation of the equivalent U value of a zone of the building envelope. Scope The following types of construction are covered: Curtain Walling: Stick system, Unitised, Bespoke, Panellised Walls Insulated panel walling Rainscreen Walling: Integral and Overcladding types Slope Glazing |
