Hi, im working in version 4.0 of this credit template. The opportunity to choose between the following is given:
"provide outputs from Load Calculation software or design spreadsheets that incorporate, at a minimum, space type, activity level, design operative temperature (heating/cooling), design humidity range (heating/cooling), and design air speed."
or
“Project will use Table IEQc7.1-1 to document space design parameters. Each room type in the project is only required to be listed”
When choosing the first alternative the following is required:
Upload IEQc7.1-1. Upload appropriate Load Calculation Software outputs or design spreadsheets. See Credit Resources for acceptable programs and the required outputs.
But the Credit Resource tab does not provide any further information.. Do anyone have knowledge regarding what kind of programs that is acceptable.
If possible, can information from the energy program used for EAp2/c1 be used?
If the second alternative would be our compliance path, we would have to list around one thousand different room types. Would it be possible to only list a sample of rooms to show compliance due to these circumstances?
Thanks! /Veronika

The documentation requirements vary based on the type of HVAC systems and building occupancies. With either alternative, it is reasonable to group together spaces with similar activity levels, design temperatures, and anticipated attire. For example, a typical office building may include offices, conference rooms, workrooms, break rooms, corridors, storage rooms, and restrooms. Although the metabolic rate will be higher in the some spaces (e.g. corridors and workrooms) than others (conference rooms and offices), the anticipated attire and design temperatures are likely similar and the information can be provided as a range of conditions. Even in an office environment, the typical clothing allowance for male and female employees is likely to vary. Alternatively, a school may contain spaces with significantly different activity levels, clothing allowances, and/or space design temperatures and require reporting different design criteria for several space types (e.g. gymnasium, classrooms, cafeteria, etc.).
Generally, it is sufficient to provide the design parameters used to determine the indoor design conditions (activity level, clothing allowance, etc.), the program with summer and winter indoor and outdoor design conditions used to size the HVAC systems. Additional information on how humidity will be controlled during low cooling load conditions may be required for packaged single zone equipment and facilities using natural ventilation strategies, but in some climate zones humidity is not an issue. The acceptable load calculation software would include programs that can perform the simulations required for EAp2/c1, but is not necessarily limited to those programs.
