Equipment heat gain is often small at space temperatures above approximately 1C. @ As discussed in the earlier postAbout Air Changes, we have to consider several aspects of the design of the air volume supply. Secure .gov websites use HTTPS No, thanks. The placement and location of outside air intakes is critical to the safety of the occupants inside a building and must be in compliance with the security requirements of the building, as described in Chapter 8, Security Design. Table 5-2 provides a guide for minimum separation distances between ventilation air intakes and other building features. From a design-engineering perspective, there are two important implications: The ASHRAE Heat Balance Method states that the sum of all space instantaneous heat gains at any given time does not necessarily (or even frequently) equal the cooling load for the space at that same time. ASHRAE/ANSI Standard 203-2014, Method of Test for . Internal Heat GainOccupancy Levels. The ASHRAE Heat Balance Method was first definedas the preferred method for Load Calculations in the 2001 ASHRAE HandbookFundamentals, and it is now the most widely adopted non-residential load calculation method by practicing design engineers.
