An example of results table:

Exemple de tableau de résultats

Explanation of the results table:

Inside temperature
(°C)

Average inside air temperature

Inside day temperature
(°C)

Average inside temperature during hours of occupancy (from 7 am to 7 pm)

Operative temperature
(°C)

Average of the radiant temperature and air temperature. The operative temperature therefore includes the temperature of wall surfaces within the room.

Operative day temperature
(°C)

Average operative temperature during hours of occupancy (from 7 am to 7 pm).

Daylight
(lux)

Average level of daylight received in the middle of the room during hours of occupancy (from 7 am to 7 pm). The table below shows the recommended levels of illumination (according to the French Lighting Association).

Area	Illumination
Lobbies	Over 200 lux
Offices	500 lux
Design departments	750 to 1000 lux
Education rooms	400 lux
IT offices	200 lux

Blind position

Average position of the solar protection device with:
0 = blind fully retracted
1 = blind fully extended

Needs of heating
(kWh)

Needs of heating to maintain a temperature of 19°C by day and 15°C by night

Needs of air-conditioning
(kWh)

Needs of air-conditioning to maintain a temperature below or equal to 25°C

Needs of artificial lighting
(kWh)

Needs of artificial lighting

Total needs
(kWh)

Sum of needs of heating, air-conditioning and artificial lighting
