This report is about all Japan residential energy consumption in the methods of analysis statistical data and questionnaire research.
The average quantity of annual residential energy consumption per household in 1975, is 7.5×106 kcal.It is about 1.3 times as much as that in 1965.And it differs with region, for example, the quantity of annual residential energy consumption per household in Sapporo, city is about 3 times as much as that in Naha city.
Heating energy use in residence of Japan isn't enough now, except Hokkaido district.So, the average quantity of annual residential energy consumption per household in 1985 will be about 1.5 times as much as that in 1975.

To study the efficient use of the housing and photovoltaic, we constructed housing which has adequate airtightness, adequate heat insulating efficiency, and concrete floors, multi-ple window glasses for seasonal weather changes and much more safety. We built a house where tow people can live(160m²) and which needs only 4.9 kW of energy. We did data analysis while they were actually living there.
As a result, we could create a comfortable environment to live, keeping the temperature in summer between 28.5 and 30°C and the humidity 50%(moisture removal) and the temperature in winter between 22 and 24°C and the humidity 50%(moisture addition). Because over drying of the air was restricted, dew condensation was prevented. 4240 kWh out of 2940kWh (70 %) became surplus electric power and the rest (30%) was consumed for a comfortable living environment. It proved that we could save 42% of electric power expenses compared with that of general hausing (4 person household, 160m2) and that we could reduce more than 60% thecooling and heating capacity.

Traditional wooden houses in Kansai district have low air-tightness and heat-insulation. They are forced to live in very cold houses in winter and get ill. To change this situation, i designed and built 10 wooden houses highly air-tightend and heat-insulated in Kansai. This study is aboutthose houses. As result of this investigation, it is showed that they have very good room-climate with low-heating-cost in winter and low buiIding cost. This technology must become familiar to people in Kansai and We must make efforts that they, especially old and young people, can live in those houses with good room-climate.

複層ガラスの断熱性能は,ガラスの中央部の熱貫流率で示される.しかし,四周のスペーサ部が冷橋になり,その断熱性能は悪くなる.通常,複層ガラスの熱貫流率は,熱伝達率が一定として示されている.しかし,熱伝達率は,複層ガラスの断熱性能によって変わる可能性がある.本研究では,多種の複層ガラスの断熱性能の把握,スペーサ部の冷橋の影響範囲,複層ガラスの断熱性能を中央部とスペーサ部に分離して示す方法の検討,複層ガラスの断熱性能と使用時の温度差が熱伝達抵抗に与える影響を把握することを目的として実験を行った.得られた結果を下記に示す.1)複層ガラス中央部の熱貫流率は,3+A6+3の場合に3.20W/(m^2・K),3+A12+3の場合に2.88W/(m^2・K),3+A18+3の場合に2.75W/(m^2・K)であった.2)3+A12+3の複層ガラスの通常スペーサの線熱貫流率は,0.044W/(m・K)であった.3)3+A12+3複層ガラスの通常スペーサが,室内側ガラス表面温度に及ぼす影響範囲は,ガラス端部より5cmであった.

A low energy house with high-efficient equipments requires less energy than conventional housing. On the other hand, building materialized Photo Voltaic (PV) roof system can change a house from an energy consuming field to an energy producing field. A house with highly insulated structure and carefully designed proportion can lessen air conditioning load to a minimum level. Annual energy balance of a carefully designed low energy house with PV system can be zero. Actual low energy houses with PV system are evaluated with energy balance, energy cost, and environment load.

A solar-heat pump system was researched and developed by the authors at the Kitami Institute of Technology. Being simplified and reduced, it was introduced into a residence to test it under every day conditions for a long period.
The solar system works only for a hot water supply, and the heat pump works for space-heating using ground water as a heat source. In the usual case, two bore holes are necessary: one for production and one for returning water. However, this particular method, namde a“direct siphon well”systm, could be done by only one bore hole. Namely, a pump is set directly under the water surface, by which ground water is pumped up and forced into the heat pump, and after absorbing heat through an evaporator, the cold water is returned to a lower point in the same well. Water discharged from the heat pump flows partially into a road-heating system, and then flows out through a drainpipe. The ratio of the drainage to the returning water is 7: 3 in average for the cold seasons, and the temperature of the water pumped up is 8.5 to 9.0°C throughout the year.10 MJ / h of the extracted heat per bore hole is expected by this technique. The system is now working very well to make environment inside the house comfortable.
Advantages of the solar-heat pump system using the direct siphon well method are as follows:

With a view to prevent global warming, to evaluate the reduction of environmental burdens of recycle-oriented, energy-saving housing which uses renewable energy, such as ground source (using heat pump), to provide space heating, cooling and domestic hot water, as well as utilizing dual purpose foundation piles for ground heat pump installation, a Life Cycle Assessment (LCA) can be used to quantify the beneficial effects on both the environment of utilizing these technologies. This paper shows LCA effects of different from the house equipment and structure.

A experimental device was produced to search the thermal output of floor heating system. In this paper, the following 4 items were examined in an experiment, on the assumption that the floor heating system was used in a wooden house. 1. Supply heat flow to the floor heating system 2. Upward heat flow : Heat flow divided by the surface 3. Downward heat flow : Heat flow which is passing through the construction, to rooms beyond. 4. The ratio of upward heat flow and downward heat flow to supply heat flow In summarizing the result of the experiment, the electoric floor heating system was grouped into three types (1. A type which flooring is one with floor heating panel, 2. B type covered the floor heating panel with floorings or sheet of vinyl chloride, 3. C type which the floor heating panel is installed under the subflor, during the floor joists). The ratio of upward heat flow to supply heat flow was about 80% in A type, about 80% in B type covered with the floorings, about 90% in B type covered with sheet of vinyl chloride, about 70% in C type. A sample number of the hot water floor heating syatem was few. But its tendency was almost similar to a tendency of the electoric floor heating syastem.

本研究は，寒冷地住宅の快適性を損なわずにエネルギー消費量を低減するため，ICTと日射エネルギーを効果的に活用する北方型住宅向けエネルギー管理システム（HEMS）の構築を目的としている。この中核技術が，在室者の周囲の温度と照明を調節する室内環境制御システムと，換気のために導入される低温の外気を蓄熱した日射エネルギーで温める換気昇温器を備えた太陽熱利用システムである。前者は居室全体の平均室温や照度を上げないことで無駄なエネルギー消費量を抑えることを狙いとし，後者は貯湯タンクの蓄放熱効率を上げることで太陽熱利用システムの総合効率を向上することを狙いとした。これらの実証に向けて，既設の北方型実験住宅に太陽光発電システムやHEMSコントローラとともに上記の中核技術を適用した。在室者の周囲の温度と照明の調節には，在室者を検知して採暖や照度を制御する専用のモジュールを組み込んだ。平成25年12月初めから平成26年３月末までの期間稼動させた結果，換気昇温器を備えた太陽熱利用システムの有効性が見い出され，システム全体として快適性の改善に向けた知見と灯油使用量の低減に向けた示唆が得られた。
