Assessment methods and rating systems for buildings can help encourage clients, developers, and design teams to provide sustainable buildings which are energy efficient, material and resource efficient, offer healthier internal environments with limited waste emissions and pollution. These can provide benchmarks, introduce minimum standards, and encourage better levels of practice.

A key factor in the design of roof and wall cladding systems is the resistance to wind loading. This must be calculated for each building and correlated with the specified profile load/span tables and specified fastener capacity, type, location and spacing. This CPD gives guidance to the person undertaking a wind load calculation using specialist software and assists with the interpretation of results. In addition, it details the relevant standards, the essential input data for building type, shape, size and location plus references the key size and shape of wind loading zonal areas on the building and appropriate safety factors.

Heavy snow falls can result in damage to roofs and their supporting structures. Good building design in terms of resistance to snow loading starts with the correct specification of the roof cladding and its supporting structure. This online resource distinguishes between types of snow load, the factors affecting snow loading and snow loading calculations. By following the recommended calculation procedures, building designers can ensure that the roofs of their buildings do not collapse. All construction professionals need to be aware of the basic principles of snow loading to ensure that they play their part in specifying and delivering safe buildings.

This CPD introduces the key issues that need to be taken into account when calculating wind loadings. Buildings and their cladding are expected to withstand the worst that the weather can throw at them without risk of failure or loss of function. However, such performance is only possible due to the care that goes into their design and the attention to detail during the manufacture and installation of the building envelope. In this CPD you will examine wind forces on buildings, the factors affecting wind loading, including location, altitude and the height and shape of the building and practical considerations.

The ability of a steel framed building to perform adequately depends on good interaction between the secondary steelwork and the cladding, crucial to this interaction is the correct installation of the purlins and side rails. This CPD sets out an overview of the issues that need to be addressed in order to meet the performance criteria identified by the building designer. The CPD gives advice on the storage, handling and installation of the secondary steelwork and associated components. The aim is to promote good practice across the industry leading to improvements in health and safety, efficiency and building envelope performance.
