Alternatives to Active HVAC Systems
Course Highlights

This online engineering PDH course presents passive cooling systems which provide guidelines on choosing the proper technologies suitable to different situations.


Buildings are major consumers of energy insofar as their construction, operation and maintenance are concerned. It is estimated that almost 50% of the global energy demand is due to buildings with active HVAC equipment being the highest contributor. Thus, the energy conscious architecture has evolved to address these issues. It involves the use of eco-friendly and less energy intensive building materials, incorporation of passive cooling techniques in building design and integration of renewable energy technologies.


Passive cooling methods maximize the efficiency of the building envelope by minimizing heat gain from the external environment and facilitate cooling by air movement, ventilation, night cooling, evaporation, desiccant dehumidification and earth coupling to name a few. All these techniques require little or no input of electrical energy. Even when these alternatives cannot avoid the use of compressive cooling systems completely, their role can optimize the energy consumption and the peak electric load.


This 6 PDH online course is aimed at students, mechanical engineers, architects, facility managers, environmentalists, energy auditors and anyone interested in gaining a basic understanding of cooling systems.
