Photovoltaic panels (PV) are being used increasingly to reduce the carbon impact of new single-storey industrial buildings. This thesis investigates the application of PV panels in conjunction with an asymmetric building shape to optimise the design of a single-storey building for net-zero carbon. The design optimisation of both symmetrical and asymmetrical steel portal frames is considered. Three different types of portal frame were considered, those made from: rolled sections (Le. Universal Beams), fabricated sections welded from three plates, and finally, fully tapered sections. The benefit of increased solar radiation on the southward side in addition to the asymmetry allows for improved carbon offsetting potential, which is a very desirable attribute for buildings attempting to meet the new tighter net-zero carbon compliance levels. Asymmetry has been shown to allow building configurations with lower embodied energy with similar carbon offsetting performance to symmetric or less asymmetric counterparts. Asymmetry was shown to allow for both material and therefore cost savings without changing the building footprint. The structural steel weight was found to have a minimal impact on the energy optimisation. However, the energy optimisation has significant impact on the structural design as it determines the optimum degree of asymmetry. This means that a recommendation of uncoupled design optimisations is made where first an energy optimisation is used with an estimated steel weight to identify a favourable asymmetry configuration (up to 80%) for the steel design to use within its own optimisation. This method would be of particular use in the code compliance of new zero carbon non domestic single storey steel buildings
