Measurement of embodied carbon and energy of HVAC facilities in healthcare centers

The design of a sustainable building should include reduction its energy consumption, by considering the embodied and CO2 emissions generated during material manufacturing, transport construction processes. A Heating, Ventilation Air Conditioning (HVAC) facility in buildings consumes large amounts energy. aim this work is to quantify carbon HVAC systems installed healthcare centers. For purpose, 6 centers region Extremadura (Spain) -projected between 2006 2009 built 2007 2010- were analyzed. results show that -considering installations lifetime estimated at 15 years-is equivalent emitted for 2.3 years operation phase, approximately 2.65 times amount used one year phase. Particularly, average 48.95 kg 587.32 MJ per m2, respectively, discarding environmental impact refrigerant gases. Additionally, different reference indicators are proposed calculate both parameters according structural variables given center, including number users, staff, installation costs, electrical power annual consumption.
