Case Study: Thermal comfort and Urban Heat Island

Today we are starting to present you a number of case studies introducing different aspects of microclimte simulations with ENVI-met.

Many of you might have suffered under severe heat waves in the last weeks. Especially in large cities the Urban Heat Island effect often has added 2 or more degrees to the already hot air temperatures.

Our first case study shows how outdoor thermal comfort can be improved by the usage of vegetation and water features. In the context of urban microclimates, thermal comfort is the key indicator to describe peoples’ subjective experience of temperature in open spaces. It summarizes the impacts of sun, wind, air temperature and humidity on the thermal sensation. To understand the thermal performance of a city at block or district level, a holistic  simulation of all elemental and architectural factors must therefore be performed.

The Case Study: Thermal Comfort provides both ENVI-met model imput files as well as precalculated result files for immediate analysis.
