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.

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

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. Improved human health and comfort. A test model of a green roof was built at the alternative energy. Experimental heat transfer study on green roofs in a semiarid climate during summer 1.

Green roofs provide aesthetic value and habitat for plant and animal species. During the last few years several cities in north america have seen a surge in interest in installing. 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.

It is a simple concept but describing mathematically how the heat comes and goes can be very difficult.
