Abstract

Recently, abnormal climatic conditions have been reported around the world. The reason for this is presumed to be global warming due to increases in the amount of atmospheric carbon dioxide. In September 2013, the Intergovernmental Panel on Climate Change (IPCC) approved the Fifth Assessment Report in the Summary for Policymakers. The report stated that the global mean surface air temperatures over land and oceans increased over the last 100 years. The Japan Meteorological Agency reported in February 2014 that the global average surface temperature for the year 2013 was estimated at +0.20°C above the 1981–2010 average and ranked as the second warmest on record since 1891, a period of 123 years. Many countries have experienced a wide range of temperatures in recent years. The most comfortable temperature is said to be about 23°C with relatively low humidity. This temperature can be achieved in buildings by applying an inorganic coating known by the trade name “Adgreencoat” to walls, roofs, etc., of a variety of buildings, including factories. This inorganic coating can reflect solar radiation and thus control the temperature of a room. This paper describes the control of temperature by using an inorganic coating.

The main conclusions discussed in this paper are as follows: (1) Adgreencoat efficiently reflects solar light and prevents heat accumulation because of its ability to release absorbed heat. This is a coating designed for heat island measures.(2) Adgreencoat can lower the temperature of external air-conditioner units and contribute towards saving energy.
