Building cooling load

Building cooling load

The hourly amount of heat that must be removed from a building to maintain indoor comfort, measured in British thermal units (BTUs).

2010) found that plant-covered walls can reduce building cooling load significantly in a northern region of Greece.
GREEN MARK PEAK BUILDING COOLING LOAD RATING <500 [greater TON than or equal to] 500 TON MINIMUM DESIGN ANNUAL SYSTEM EFFICIENCY (KW/TON) CERTIFIED 0.
He says that this may also be due to other factors like under estimating the building cooling load where the consultant may choose not to design to that point in order not to over size their building capacity and equipment.
Because the solar radiation on the outside envelope-surfaces has a small effect on the building cooling load, the errors of prediction value are acceptable.
The peak-shifting controller must find the time-shifted cooling load trajectory that minimizes input energy, given a building cooling load trajectory and the performance characteristics of a chiller and associated mechanical (transport) equipment.
However, the direct measurement of the building cooling load might be inaccurate or unreliable because of uncertainties associated with the measurement instrument.
1 [ASHRAE 2004b]) and knowing that the supply flow rate is already determined considering the building cooling load (not a variable in Equations 5 and 6), the coil cooling load is a function of ERV sensible and latent effectiveness.
When the building cooling load exceeds the heating load the control system determines whether to direct the surplus thermal energy into the GHX for later use/later rejection or to reject it to the closed-circuit cooling tower if that process consumes less energy or costs less.
The differences in these methods lie mainly in how the instantaneous building cooling load is measured (Honeywell 1997).
In addition to active daylight harvesting, occupancy sensors are deployed throughout the building to ensure that lights stay off while spaces are unoccupied, further reducing the building cooling load.
In general, the chiller load at any time interval is the sum of the building cooling load and the storage charging rate (negative for discharging) or
