Globally, buildings are responsible for approximately 40% of the total world annual energy consumption [1]. Most of this energy is for the provision of lighting, heating, cooling, and air conditioning. Increasing awareness of the environmental impact of CO2 and NOx emissions and CFCs triggered a renewed interest in environmentally friendly cooling, and heating technologies. Under the 1997 Montr...

15 صفحه اولInterrelationships between the Environment and Food Production
Food has to be extracted from the natural environment of land, water, climate, flora, fauna, solar energy, fossil fuels, and other natural resources needed for the production of crops, livestock, and the like essential for adequate diets. These requisites for food production must be provided by the Earth’s materially closed, finite, and nongrowing ecosystem with a limited throughput of solar en...
