    Building sector consumes one third of world's resources. Building currently shares approximately 40% of energy in most of the countries and are considered among the largest end-use sector. As per International energy agency (IEA) world energy consumption and green house gases level is going to increase rapidly every year. IEA recognize the ...

  3. Thermal efficiency - Wikipedia

    en.wikipedia.org/wiki/Thermal_efficiency

    For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the coefficient of performance or COP) is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is ...
