The use of “shades” for building windows is an important way to conserve energy in basic building design; it also has a profound influence on the power consumption of air conditioning and lighting equipment. 　　Through a full-scale house-in-house experiment, leveled shades were installed above the outdoor openings facing west. During two equinox seasons, namely the autumnal equinox to the winter solstice and winter solstice to the spring equinox, two blinds angles for the leveled shades were used to measure and test the indoor temperatures and effects. Three conclusions were drawn from the empirical study: 1. From the autumnal equinox to the winter equinox, the blinds angles of 0 degree and 90 degrees showed no significance in terms of full-day temperature difference and cooling effect; from 10:00AM-02:00PM, the installed leveled shades with blinds angles of 0 degree and 90 degrees had the cooling effect of 0.9℃. 2. From the winter solstice to the spring equinox, the full-day temperature difference and cooling effect was not significant at the blinds angles of 0 degree and 90 degrees. On the other hand, from 10:00AM-02:00PM, the installed leveled shades with the blinds angle of 0 degree were superior to the blinds angles of 90 degrees. For the house-in-house laboratory, the indoor or temperature drops did not exceed 0.8℃ on average. 3. For two time periods, namely from the autumnal equinox to the winter solstice and from the winter solstice to the spring equinox, from 10:00AM-02:00PM, the installed leveled shades with blinds angles of 0 degree and 90 degrees, the indoor temperature drops did not exceed 1℃. This indicates the leveled shades installed above the openings facing west for the house-in-house in the laboratory showed no significant differences as far as the effect of indoor temperature drops is concerned.
