Paper Abstract

Reducing the energy used for air-conditioning and lighting is important not only for achieving energy savings in buildings but also for realizing urban and global environmental conservation. For solar shading and daylighting, we considered the wavelength characteristics of solar radiation including the invisible nearinfrared range and proposed window systems that utilize innovative special films and technologies that were originally developed for other purposes such as large-screen TV displays and printing. The window systems reflect, refract, or transmit radiation in specific ways depending on its wavelength, for example, reflecting only near-infrared radiation toward the sky in order to reduce the air-conditioning load of buildings and also avoid adverse thermal effects on the urban environment. While near-infrared radiation is blocked, visible light is introduced and directed toward interior ceilings. The effects of these window systems were demonstrated based on measurement results.

Corresponding author Biography

Takashi Inoue is currently a Professor of department of architecture, faculty of science and technology at Tokyo University of Science, Japan. He graduates from the department of architecture in  the University of Tokyo in 1977, obtains degree of Doctor of Engineering from the University of Tokyo, and has over 35 years of experience in the research field of energy conservation concerning buildings and houses, particularly concerning building envelopes, such as development of high performance window system, combination control for solar-shading and daylighting. His works won many prizes, such as SHASE awards (both for Technology and Thesis), PLEA2000 Best paper award, Sustainable building award (by the Minister of Land, Infrastructure, Transport and Tourism), Environmental and equipment design awards, Japan lighting award, etc. He worked also as an expert reviewer of WG3 AR4 IPCC. He is last president of the Society of Heating, Air-conditioning and Sanitary Engineers of Japan (SHASEJ), which celebrated 100th anniversary in 2017.
