Then a new method namely Stochastic Analysis is presented to determine the outdoor synthetic temperature (OST), which fully considers the randomness of weather and internal casual gains, and the thermal performance of buildings. The concept of OST enables the design of space heating system to be the trade-off between economics and risk. Finally, case studies of the influence of different building components on OST of a residential room in Beijing have been studied, which shows that OST depends upon building structures as well as weather conditions. It is recommended that OST rather than ODT should be employed in heating load calculation hence, sizing equipment for space heating systems.</p>10aheating load calculation10aoutdoor design conditions10aresidential buildings10astochastic analysis10athermal performance of buildings1 aHong, Tianzhen1 aJiang, Yi  uhttps://simulationresearch.lbl.gov/publications/outdoor-synthetic-temperature
