SPUCAL_mrt as a new model for estimating the mean radiant temperature in arid lands

摘要

This paper presents a thorough study on the Mean Radiant Temperature, which is considered as the most important factor for estimating outdoor thermal comfort, especially in sunny climates. T_(mrt) Summarize all thermal radiations, including short and long waves radiations coming up to the human body that's why T_(mrt) is so complicated in time and space especially in open urban spaces. In this paper we present various methods to assess and estimate T_(mrt), mathematical and digital models are discussed and in conclusion we present a new digital platform SPUCAL_mrt, which evaluate and simulate the T_(mrt) in open urban space in arid lands to reach the main objective 'to a sustainable and comfortable built environment'.
