Quantifying the thermal performance of windows to promote energy conservation in buildings
Architectural Environment
NIMIYA Hideyo
Background and objectives of activities
It is well known that curtains and blinds attached to windows provide thermal screening and insulation. However, the extent to which they contribute has not been quantitatively assessed. For this reason, curtains and blinds are not included in energy conservation standards for homes. In my lab, we are working on quantifying the thermal performance of curtains, etc., and linking it to energy conservation in buildings.
Summary of Activities
Equipment has been developed to quantify the thermal performance of window accessories such as draperies and is being measured on the roof of the school Building. The thermal performance of blinds, roll screens, external shades, and lace curtains have been quantified so far. We are attempting to systematize evaluation methods for a wide variety of products in the market.
Expected Benefits
By quantifying the heat shielding and insulating performance of curtains, etc., the energy-saving effects of buildings can be clarified. By disseminating information on the use and energy-saving effects to citizens and the government, it is expected that society as a whole will work to conserve energy in buildings.
