The theme in this case was how to construct a low-cost,. energy-saving building with a beautiful design, within the constraints of an extremely low budget. This is a public facility, so initial construction costs could be secured, but the biggest issue was reducing annual running expenses (including operating costs such as water, lighting, heat and other utilities) after the structure was completed. In glass architecture which has previously been showcased in magazines and other media, most of the structures have been large-scale, and energy conservation was based on using large amounts of double-glazing and Low-E glass. But in buildings like this facility, where the construction budget is low, increasing the glass area increases the construction cost, and it is virtually impossible to use Low-E glass or energy-saving glass. Thus, it was decided to use singlepane glass in this plan, and the biggest issue for the environmental plan and architectural facilities was improving energy conservation through approaches such as utilizing natural energy and developing new air-conditioning systems. In this research, we conducted actual measurements of the environment after completion, in the intermediate periods, summer and winter. The results are used to clarify issues such as the living comfort of small-scale glass architecture, and the development of energy conservation systems
