IMPACT OF A VERANDA ON THE REDUCTION OF THE ENERGY CONSUMPTION IN RESIDENTIAL BUILDINGS : AN APPLICATION OF THE CLIM2000 SOFTWARE
Résumé
In this paper, the impact of a veranda (attached
sunspace) on energy consumption is analyzed by
numerical simulations (Clim2000 software) for two
different configurations : a (existing) residential
individual house and a (new) apartment building. The
simulations are run by October to May (warm
season).
The model of veranda used in these studies is
described with a focus on the calculation of the sun
patch location.
The main parameters are the lodging type and
insulation (bad, average or very good), the veranda
type (projecting or built-in), glazing (classical, strong
insulation or low emissivity) and size, the separation
between the veranda and the lodging (type and
surface of the glazing part).
The utilization of a veranda allows energy savings
from 4% up to 23% with the best parameters and adds
a comfortable room for autumn, best days of winter
and spring.
