Green Roof Heat Transfer

Thermal mass the ability to store heat in something heavy like a big rock or a chunk of steel or a potato.

Green roof heat transfer. 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. 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. Improved quality of life. Improved human health and comfort. 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. Green roofs provide aesthetic value and habitat for plant and animal species. Then the heat transfer processes in green roof with heterogeneous approximation is a porous medium where the heat transfer process takes place. In the case of a green roof that material is water.

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.
