Open the CIPO recordAbstract From the Canadian patent
In order to meet the energy demand for the lighting and heating of a room (2) in a building (1) windows (4) and non-transparent wall elements (3) of the outer wall are designed so that their heat transfer coefficients (kF, kw) are below 1 W/m2.K. Electric lighting fixtures (7) and heaters (8) which have at least approximately equal power ratings are used for lighting and heating. Due to the heat transfer coefficient values as specified above, it is possible to avoid cold air subsidence at the windows (4) and draughts; thus a, relatively small amount of energy supplied through the lighting units (7) and/or the heating units (8) is sufficient for meeting the requirements.
