Abstract: ¬¬The objective of the paper is to show how window design could influence the peak cooling load, daylight availability and direct sun penetration for a south facing office room in North European circumstances latitude about 59 ~ 60. A daylight window is compared with an ordinary window to find out the design consequence differences. Both size and cost of the HVAC system needed to avoid unacceptably high room temperatures in office buildings depend on the peak load. In office rooms with windows this peak load is usually decided by the solar irradiation. Therewith the architectural design is decisive for the HVAC solutions needed. The Seattle Daylighting Lab heliodon table has been used to analyze daylight window potential in North European circumstances in decreasing the peak cooling load and glare from direct sun by blocking the direct solar rays from entering the room. Finally, outgoing from simulations, daylight and solar tests, the possible combina!
tion of window glass share and solar factor for fulfilling the requirements for the highest accepted dimensioning cooling load and lowest accepted daylight level for daylight window compared to ordinary window are presented.
Keywords: Commercial buildings, building design, window share, solar factor, cooling load, daylight factor, daylight window.
