3. Input Data 3.1. Local Weather The first data to be transferred in to the HAP program was the information about geographical location of the building, the nature of local time and soil properties. Parameters like the temperature, humidity and solar radiation conditions are central to the sizing and simulation processes. Two distinct kinds of weather data exist: 3.1.1. Design Weather Data Used to perform cooling and heating design load estimates (see append A). 3.1.2. Simulation Weather Data Required to perform 8760 hour energy simulations. Results of these simulations were used to compute annual energy use and energy. 3.2. Cinema Theatre Space The cinema space must be defined so system design calculations or energy simulations can be performed. A space consists of a number of walls, roofs, windows and internal heat gains that influence heat transfer into and out of the space (see append B) 3.3. Schedules Schedules define the hourly and daily behavior of the characteristics of a building and its HVAC equipment. Each profile contains data for one 24 hour period and are assigned to the different days of the week and months of the year (see append L). 3.4. Systems The components included on the program were fans, coils, ductwork, supply terminals and controls. Also when performed the energy analysis of other components like heat pumps, electric resistances and combustion heating components the information collected from there were considered by the program (see append C). 3.5. Plants 4. Sizing A Plant is the equipment and controls which provide chilled water to cooling coils, or hot water or steam to heating coils. Examples include chiller plants, hot water boiler plants and steam boiler plants (see append D). This is a calculation process to determine the equipment specifications like airflow rates, supply terminal characteristics and coil capacities for HAVC systems (see append E).
5. Simulations System simulation reports provide information about system and plant operation and energy use during a typical year (see append F, G, H, I). 6. Results The simulation results and benchmarking were made only for cooling (this is a Carrier Developed Program). The results are described for each component: Supply Fan: • CAV (Constant Air Volume); Floor Air Supply: 2403,5 €/year; • CAV (Constant Air Volume); Ceiling Air Supply: 1998,6 €/year (16,85 % less); • VAV (Variable Air Volume); Floor Air Supply: 261,1 €/year (89,14 % less); • VAV (Variable Air Volume); Ceiling Air Supply: 213,1 €/year (91,13 % less); Chiller Plant: • CAV (Constant Air Volume); Floor Air Supply: 684,8 €/year; • VAV (Variable Air Volume); Ceiling Air Supply: 423,5 €/year (38,16 % less); • CAV (Constant Air Volume); Ceiling Air Supply: 415,1 €/year (39,38 % less); • VAV (Variable Air Volume); Floor Air Supply: 333,3 €/year (51,33 % less); Final Results: • CAV (Constant Air Volume); Floor Air Supply: 3088,3 €/year; • CAV (Constant Air Volume); Ceiling Air Supply: 2413,7 €/year (21,84 % less); • VAV (Variable Air Volume); Ceiling Air Supply: 636,6 €/year (79,39 % less); • VAV (Variable Air Volume); Floor Air Supply: 594,4 €/year (80,75 % less); Also it’s important to compare the loads between cooling and heating coils: Cooling Coil Loads: • CAV; Floor Air Supply: 16709 kWh / year 3088,3 €/year; • VAV; Ceiling Air Supply: 6515 kWh / year 423,5 €/year; • CAV; Ceiling Air Supply: 9431 kWh / year 415,1 €/year; • VAV; Floor Air Supply: 5703 kWh / year 333,3 €/year. Heating Coil Loads: • CAV; Floor Air Supply: 35055 kWh / year • VAV; Ceiling Air Supply: 0 kWh / year (Not Simulated) • CAV; Ceiling Air Supply: 57783 kWh / year • VAV; Floor Air Supply: 0 kWh / year (Not Simulated)
