Nonresidential building cooling and heating load (manual methods)

In nonresidential buildings, it is important to include

(1) the time lag in conductive heat gain through opaque exteriors, and

(2) the thermal storage in converting radiant heat gain to cooling load.

Calculation of a building cooling loads requires detailed information on:

• building characteristics (materials, size, and shape)

• configuration (location, orientation and shading)

• outdoor design conditions

• indoor design conditions

• operating schedules (lighting, occupancy, and equipment)

• date and time

• additional considerations (type of air-conditioning system, fan energy, fan location, duct heat loss and gain, duct leakage, type and position of air return system,…)
