Occupant schedule (High) Equipment load (Low) Equipment load (High) In order to insure that the correct numbers of occupants are present at any given hour, it is necessary to multiply all diversity factors by all occupant loads for each space and sum the total occupant count for the building.
Description of the design comfort conditions: The conditions should combine indoor and outdoor factors at which occupant thermal comfort shall be evaluated and cover the most challenging scenarios for occupant comfort. Every unique combination of space and representative occupant must be evaluated under at least two conditions: cooling and heating.
Building occupancy classifications refer to categorizing structures based on their usage and are primarily used for building and fire code enforcement. They are usually defined by model building codes , and vary, somewhat, among them.
The selection of occupancy sensing devices depends on the size of the space being monitored, the budget for sensors, the desired accuracy, the goal of the sensor (detecting occupant presence or count), and security considerations. Unlike occupant presence data, acquiring occupant preference data requires direct feedback from building occupants.
The UFAD system was originally introduced in the 1950s for rooms with high heat loads and raised floors systems for cable and equipment management (e.g. computer rooms, control centers, etc.). The system was introduced into office buildings in the 1970s in West Germany, with the addition of occupant-controlled localized supply diffusers.
Occupancy can also refer to the number of units in use, such as hotel rooms, apartment flats, or offices. When a motel is at full occupancy, it is common practice to turn on a NO VACANCY neon sign. Completely vacant buildings can also attract crime. A 2017 study found that demolishing vacant buildings "reduce crime by about 8 percent on the ...

Reducing energy loads of main systems equipment providing heating, cooling and water heating can be achieved by upgrading physical equipment including replacing older equipment with newer, more energy-efficient units, upgrading the building envelope with insulation and higher-grade windows, creating more efficient zoning within heating/cooling air distribution ducts, and deployment of advanced ...
