Integrated Daylighting and Passive Solar heating in Office Buildings in Cold Climates

摘要

A method is described for designing energy-efficient office buildings in cold, high-laitude locations. the dising strategy focuses on an equatorial-facing fenestration system ocmbining daylighting nad direct-gain passive solar heating. Response to summer conditions ocmbines solar shading protection and ventilative coolign. The deisgn procedure uses a spreadsheet framework linking existing simplified methods. The daylighting anlaysis uses location-speicfic data on diffuse daylight on vertical surfaces to estimate energysavings fom hgih-efficiency window and room configurtions in combination with a daylight-responsive electriclighting system. The passive solar heating analysis is a genratlization of a solar load ratio method. The emphasis of this approach is on very high computational efficiency permittingtherapid and comprehensive examination of a large number of options early in design. The procedure is illustrated for sapporo, Japan, testing te relative significance of varius design options relative ot a base case. In general, consumption of ligting electicity may be reduced by 64-97
