Abstract: Photosynthetically Active Radiation (PAR) and energy demand are critical factors to justify the performance of greenhouses in food and farming industry, which could be significantly affected by configurations and orientations of greenhouse. In Beijing, one typical greenhouse model with two types of roof (A-frame and Barrel-vault) and orientations (south-north; east-west) have been assessed using RADIANCE (ray-tracing packages) & TRNSYS (energy package), in terms of PAR received at lower vertical planes of vegetation shelves, and heating and cooling demands in the whole space. Several key findings have been achieved, aiming to produce optimized design strategies to improve the availability of PAR for a faster growth of plant, and at the same time reduce energy consumption in greenhouses.
