1. Advanced Energy Engineering Technology Modeling Building Energy Systems Session 9: Modeling heating and cooling systems

2. Topics covered in this class session: Heating systems—standard options Cooling systems—standard options Synergies between the building and its HVAC systems

3. Heating systems—standard options – may not need much attention in Hawaii but important to know Forced air heating Heat source—burners/coils Air handlers Ductwork Hydronic heating Boilers Pumps and piping Radiators and heated floors

4. Cooling systems—standard options DX coil systems Heat pumps Air-to-air Geoexchange Chilled water systems

5. Thermal storage Chilled water storage Hot water storage Ice storage

6. Synergies between the building and its HVAC systems Lighting versus cooling The balance between wall and roof insulation and the HVAC system Window u-value versus HVAC systems Window solar heat gain versus HVAC systems

7. More synergies Impacts of heat from lighting on building cooling system Interplay of lighting energy and heat, daylighting, and building HVAC The balance between ventilation requirements and HVAC energy use
