Tabulated values are based on 78oF (25.6oC) for dry-bulb temperature are estimated to use between 20 to 50 percent of building energy use, according to ASHRAE. There are three Heat Balances shown in Figure 1 of the Heat Balance (HB) Method and two of those Heat Balances are applied to each surface of a space or room. If air changes define the airflow, and it supplies to several spaces, always check the supply temperature. In general, it is important to keep within an RH range of 30 to 70%. In the same way, where large latent loads are generated, is preferably to extract the air instead of dehumidifying. A gym use is unique due to the activity taking place and how much heat and moisture is generated, and if you have a pool that further adds to complexity. Do not forget to include the heat generated by the supply and/or return fans. 0 A .gov website belongs to an official government organization in the United States.
