10 5 Lighting The model is using the Space by space lighting power calculation method. Lighting power densities have been calculated using ASHRE 90.1 maximum sensible gain of watts per square foot values Power (kbtu/h) Sun Mon Tue Wed Thu Fri Sat Sun Date: Sun 08/Jun to Sat 14/Jun Total lights energy: (rockwell.aps) Figure 11: Typ. Weekly Lighting Loads 6 HVAC Systems 6.1 Proposed Systems HVAC Systems analysis is incomplete. Rockwell Hall IES VE Model consists of ASHRAE 90.1 data for systems. Systems survey is required to complete proposed systems setup. James Construction created a simple systems network for the building to complete the baseline simulation analysis, including the following Heating and Cooling information.
