Document Summary
That condition of mind which expresses satisfaction with the thermal environment and is assessed by subjective evaluation. Objective is to provide thermal conditions to building occupants such that the fraction of dissatisfied people is at a minimum. An angle-factor weighted average of all surface temperatures that surround the. Imbalances (i. e. , super-hot ceiling), aka radiant temperature asymmetry also causes occupant. discomfort, but this is not accounted for in the simple one or two-node model. The thermal load is the surplus or deficit of heat generation (i. e. , negative means net heat loss; positive means net heat gain) Localized and subtle causes of thermal discomfort: Easy-to-use moveable shading with very low visible transmittance. Allow deep penetration (window geometry, wall and furniture geometry, reflective. Keep windows above workplane (pretty useless below) Daylight autonomy (da) is defined as the fraction time of any surface in a building (a.
