Green Roof Heat Transfer

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.

Green roof heat transfer.

Then the heat transfer processes in green roof with heterogeneous approximation is a porous medium where the heat transfer process takes place. It is a simple concept but describing mathematically how the heat comes and goes can be very difficult. Experimental heat transfer study on green roofs in a semiarid climate during summer 1. This work reviews and criticisms the most important mathematical models for heat and mass transfer in green roofs developed and published during the last three decades.

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. A test model of a green roof was built at the alternative energy. A special characteristic of this type of heat transfer is that the material can be cooler than the surrounding air making the wet surface a little cooler than the ambient air temperature. During the last few years several cities in north america have seen a surge in interest in installing.

They improve human interaction with nature by introducing green space into the built environment. 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. Improved human health and comfort. In the case of a green roof that material is water.

Improved quality of life.
