Green Roof Heat Transfer

In the case of a green roof that material is water.

Green roof heat transfer.

Improved human health and comfort. They improve human interaction with nature by introducing green space into the built environment. Thermal mass the ability to store heat in something heavy like a big rock or a chunk of steel or a potato. Improved quality of life.

Traditional roof green roof n sensible et r q q q substrate 0 where r n net radiation q sensible sensible heat flux due to convection q et latent heat flux due to convection q substrate roof conductive heat flux through roof n sensible r q q roof 0 energy balance. A test model of a green roof was built at the alternative energy. Then the heat transfer processes in green roof with heterogeneous approximation is a porous medium where the heat transfer process takes place. The review let see the evolution of the mathematical modeling in green goof it start with an analysis of the first attempts to model the heat and mass transfer and proceeds to the most representative current models.

Experimental heat transfer study on green roofs in a semiarid climate during summer 1. It is a simple concept but describing mathematically how the heat comes and goes can be very difficult. In this study the green roof is considered as a porous media in order to consider the heterogeneous effects where the porous medium is made of several phases and several components. During the last few years several cities in north america have seen a surge in interest in installing.

Green roofs by reducing heat transfer through the building roof can improve indoor comfort and lower the incidence of heat stress associated with heat waves.
