To keep dry air flowing through building cavities, systems shall be designed with sequence of operations that assure continuous positive pressure with respect to the outdoor environment until the outdoor temperature falls below 4.5C (40F), when the building pressure shall be brought to neutral. t General ParametersHVAC system parameters are provided here for reference, but specific energy performance directives are also listed in 10 CFR 434. %PDF-1.7 % . @ G H M Q S U e ' A B I J K M N P Q T U V W X Y Z [ \ ] ^ j h, Uh, j h, Uj%1 h Uj h Ujr h Ujk h Uh=c* j h Uhea hF When available, manufacturer-provided heat gain and usage schedules . Accurate model geometry is necessary and should account for all surfaces of a space or room including the internal walls, ceilings and floors. For detailed calculations, you should get the input from your Electrical Department. t t On some occasions, a ground-contact floor with high thermal mass may even remove heat from a space during a cooling load calculation. Transmission. See AMCAs revised Standard 230 first Scope. Typical values may be 90% for occupants, 80% for lighting and 50% for plug load equipment, depending on the space function and operation. There is nothing new under the sun with this contribution. Committee results will be presented to the 62.1 Committee as submissions for inclusion in appendices of the Standard.

Supply air temperature reset control shall be utilized to extend economizer operations and to reduce the magnitude of reheating, recooling or mixing of supply air streams. In Chapter 18 of the ASHRAE Handbook Fundamentals, you can find tabulated loads for different activities: The heat gain from equipment is in many cases the main contribution to the total heat gain in a room. While the typical load calculation is for the design day, hourly calculations for each month should be calculated in order to account for. The using of non-specific pharmaceutical HVAC software like HAP could be very interesting to perform an energy analysis of the plant. Large locally heat-generating machines like welding stations, depyrogenation tunnels, may be interesting to remove the air just above heat generation instead of removing it from the HVAC system. When predicting annual building energy/cost/carbon performance, we do not encourage this approach and use hourly operational profiles instead. According to ASHRAE, the growing use of plug loads in buildings as well as insufficient data on how much energy they generate present a challenge to engineers in determining how to best cool a building. EnergyPlus does have equipment models of water-source heat pumps, but these equipment models do not appear to provide for variable volume airflow.
