MECH 673 ENERGY EFFICIENT BUILDINGS WITH GOOD 3 CR.

The course covers energy consumption standards and codes in buildings; energy conservation measures in built in environment to enhance the building’s energy efficiency while maintaining space and indoor air quality requirement; fundamental ventilation, indoor-air-quality, infiltration natural and mechanical ventilation, importance and impact of indoor air quality on health and energy performance of the building system; and ASHRAE requirement for ventilation. Particular focus will be given to green energy alternative measures. An overview of the different heating, ventilation and air conditioning system is covered. Performance and energy consumption of the conventional air conditioning system (constant and ) as well as the hybrid integrated air conditioning systems will be discussed and compared. The course will include several demonstrations of concept experiments. Prerequisite: MECH 310.
