Abstract
In recent years, “green curtains” have become one of the most prevalent thermal mitigation methods in Japan. They can be considered as green infrastructure for achieving thermal comfort and reducing energy use. To examine the thermal mitigation effect of the green curtain for practical applicability in the condominium, the indoor and balcony temperatures for 48 days both in households with and without green curtains were analyzed. The balcony globe temperature of the households with green curtains was 0.6 °C lower than that of the households without green curtains, during air-conditioner usage. Furthermore, the air-conditioner usage time of the households with green curtains was 40% less than that of the households without green curtains. The results showed that green curtains are effective for achieving both thermal mitigation and energy saving in a condominium.
Highlights
A green wall comprises plants grown in supported vertical systems that are generally attached to an internal or external wall, in some cases these vertical systems can be free-standing

Summary
Reducing the heat load of building walls is one of the most important solutions for environmental problems in countries where the summer season is long. Reducing the thermal load of the external walls of a building will cause the thermal environment of a room to improve. In other words, reducing the heat load of the external walls of a building is one of the important initiatives for ensuring the comfort of the residents. The construction-technology-based thermal-mitigation method can improve the thermal-insulation performance of walls, roofs, and windows. Greening is one of the thermal mitigation methods. Green walls incorporate vegetation, irrigation, and drainage into a single system. Green walls are called “living walls”, “bio-walls”, or “vertical gardens”
