Modern society, people are comfortable environment for the pursuit of building heat rising, leading to the construction of the heating and air conditioning energy consumption growing. In developed countries, can be used in construction of the country's total energy consumption accounted for 30% -40% of the economic development of certain restricted. The United States is the world's largest energy consumption country, Congress has passed the "solar heating cooling housing construction regulations" and "energy conservation building regulations" to encourage the use of new energy sources, the legal documents. Economically also take effective measures not only in research into the use of solar energy, a lot of money, but also by the Congress to pass a tax cut of the solar system buyer preferences. As a result, the United States building solar energy development is at its fastest, whether in the construction of solar energy research, design optimization, or materials, housing parts of the structure of product development, application, as well as the formation of the real business of real estate development, the United States leads the world, At home and formed a complete system of solar energy construction industry.

The United States in the early 1980s on the Island of New Mexico by the Los Alamos scientific laboratory preparation of the publication of passive solar house design manual. In addition, the United States has also published a number of practical passive solar house building Atlas, not only to introduce a successful example of the design, but also on the principle of the sun room, a detailed description of the structure. The issuance of these books and a number of model demonstration houses set up for the American public to accept the sun room and played a role in the promotion of good. Comparing the well-known architectural model: at Princeton, New Jersey's residential Ka `B; at Bell's home in New Mexico Kelaersi; located in Santa Fe, New Mexico's Santa Fe sun room; Attas, California Kade Luo Attas Kade Luo's home, located in New Mexico, as well as residential Kelaersi Davis. The construction of these electric radiator or fireplace used for auxiliary heat source, solar energy heating rate of 75% or more, and some have reached 100%, such as residential Kade Luo Attas.

As early as age 40 of the last century, the Massachusetts Institute of Technology began to use solar collectors as the heat source heating, air-conditioning systems, has built a w experimental solar house. These experimental solar house, that was one of the first active solar house. After the age of 70; and Washington Tomasson solar house on the outskirts of Denver, Colorado and the Love of the sun room, and other active solar house model built construction. The success of these solar houses run on solar heating, air-conditioning system is technically feasible, complete, but more investment to promote the penetration of less than passive solar houses. Until the 1990s, due to the development of more efficient solar collector and absorption chillers, heat pump units were able to expand the scope of application.

Japan active in the research and application of solar houses in the area in the world. 1974 Industrial Policy Bureau of Japan formulated the "Project Sunshine" and plans to be built a few blocks of a typical solar heating air-conditioning test construction, such as Yazaki experimental solar house. Over the years and Japan's solar heating, air-conditioned building has been developing steadily and has been used in large buildings.

In addition, France, Germany, Australia, Britain and other developed countries also have very advanced technology solar architectural applications. Well-known collector of regenerative heating wall that is the way the French patent Telang Bo Felix, France and Austria on behalf of the Los solar house heating is the theory into the practical application of the first sample flats. Liverpool Wallasey in the vicinity of the St. George's County Middle School, is a direct benefit from solar houses the largest and one of the earliest model. Despite Britain's rich solar energy resources is not the secondary schools to install conventional heating system was never used.

Finally, it is worth mentioning that in the past few years has developed considerable level of development of "zero to housing" that is entirely solar photovoltaic conversion devices to provide all the necessary building energy consumption, really clean and pollution-free, It represents the construction of solar energy in the 21st century trends. Since many governments (such as the United States, Germany) have developed solar energy in the country's total energy consumption in the proportion should be more than 20% of the plan believe that this kind of "zero to housing," there will be a very good development prospects.
