Greenhouse gas emissions associated with two air-conditioning systems for a university building

Recognizing the rise of global life standards, the associated energy consumption, and the widespread use of air-conditioning systems, there is a clear necessity to evaluate the environmental loads associated with energy supply systems. This study applied the Life Cycle Assessment methodology to quan...
