A Method for Analyzing Microclimate Effect of Shaded Transitional Spaces on Outdoor Human Thermal Comfort and Building Performance in a Hot Arid Region

Abstract

Spaces are usually classified as either being indoors – frequently private or public outdoor spaces. Transitional spaces are an important aspect to the built environment as they have great potential to modify the environmental conditions of both indoor and outdoor spaces. They are the connecting space between the outdoor and indoors, between the natural climate and controlled climate. They can aid to building efficiency and to outdoor human thermal comfort. Transitional spaces in a hot arid region are crucial to maintaining the comfort of a user while being outside. The purpose of this investigation is to prove that shaded outdoor transitional spaces can lead to outdoor human thermal comfort and building performance. The problem being addressed is the lack of attention on shaded transitional spaces in a hot arid climate. Being located in such a harsh climatic environment it is important to look into the relationship between the building and its outdoor spaces as well as users. They are used to create a comfortable microclimate while transitioning into the building. A 9 step method will be proposed to defend the idea that shaded transitional spaces can lead to outdoor human thermal comfort and building efficiency. Methods being used are eQUEST Simulations, micro-climate data collection, and calculating outdoor human thermal comfort. The results confirmed the notion that shaded transitional spaces can lead to outdoor human thermal comfort and building performance. The comfort of the user was defined and the performance of the building was established through energy modeling simulations.
