considering current population rate and ratio of non renewable energies in countries' annual energy diagram which lead to increase of pollutions reeked from and irreparable effects on living environment, there will be an energy and living environment crisis in close future. so there are two main approaches that should be considered in countries' future program: change of construction ...

Thermal benefits of different green roof samples were analyzed and compared. Experimental data from ongoing green roof projects was used in a theoretical analysis of air-conditioning energy savings with different green roof applications. Thermal data was collected from a typical non-reflective (EPDM) roof membrane and model green roof systems with three types of growth media (lava, arkalyte, an...

Photovoltaic (PV) panels get hot in the sun. This decreases the operating efficiency through various means. Several approaches have been proven effective at cooling panels. Green Roofs are thermally cool, outperforming even white roofs over their life. On a hot summer day, a green roof can be 30◦C cooler than a typical roof, potentially improving the efficiency of a photovoltaic (PV) panel by a...

BACKGROUND Green roofs perform ecosystem services such as summer roof temperature reduction and stormwater capture that directly contribute to lower building energy use and potential economic savings. These services are in turn related to ecosystem functions performed by the vegetation layer such as radiation reflection and transpiration, but little work has examined the role of plant species c...

Urban green roofs are discussed as a local climate adaptation measure to limit surface warming and increase evaporative cooling by vegetation in urban environments. A five month measurement campaign was conducted to observe surface and air temperatures as well as dewfall dynamics and amounts on an urban green and co-located bitumen roof. Measurements were performed in the period from August to ...
