The document discusses the rapid growth of solar power in green buildings in China, fueled by economic development and opportunities for energy efficiency. It highlights key technologies such as passive and active solar power, including photovoltaic systems and solar water heaters, emphasizing their importance in reducing energy consumption. The conclusion asserts that solar energy integration in buildings is a crucial trend for China's future development and has global significance.

1. Solar power in green building

2. Introduction
The area of solar building in China
increases dramatically after the reform
and opening-up policy and economic
development..It is helpful for the
national economy which maintains a
sustainable, rapid and healthy
development if we seize the
opportunity to promoting building
energy efficiency. The solar building
has a good prospects and brilliant
future which can help our country to
realize the national development of the
second step and the third step in the
strategic target, and guide our country
construction and architectural
technology along with the world’s
Breakdown of the incoming solar
energy

3. Passive solar power
In passive solar building design,
windows, walls, and floors are
made to collect, store, and
distribute solar energy in the form
of heat in the winter and reject
solar heat in the summer.
Elements of passive solar design,
shown in a direct gain application

4. Active solar power
Active solar power is any solar power
device that incorporates a
mechanical device for it to
operate. In solar building, it means
the whole or part of the
application use new technology
,like solar photovoltaic and solar
thermal technology for the
building to provide energy

5. Reviews of research situation at
home and abroad
• The United States pays a great attention to the development and
utilization of solar energy. It takes effective measures to invest a
lot of money on the research of solar energy utilization and the
congress of United States made preferential policy that reduce tax
for buyers of solar system. United States is a leading position in
the world, and forms a complete solar building industrialization
system in the domestic .
• The research on active solar building in Japan makes a great
example on the world. According to the “sunshine project” which
formulated in 1974,Japan built a number of typical solar energy
heating and air conditioning experimental building . Such as the
Yazaki Experimental Building.

6. Introduction of the key technologies
• Solar photovoltaic panels
• Solar wall
• Solar heating
• Solar water heater

7. Solar photovoltaic panels
The combination of photovoltaic and
architecture has the following two
ways.One is BAPV(Building
attached photovoltaics )The other
one is BIPV(Building integrated
photovoltaics).For instance
integrating solar photovoltaic
cells,glass curtain wall, window
glass and roof tiles, so that it can
not only develop and apply the
new energy, but also decorate
landscaping.

8. An example:
"Shanghai Eco­House" emphasizes
the integration of ecological
housing design, highlighting the
amorphous silicon thin film
photovoltaic power generation
system which is a technical
highlights of BIPV. “Shanghai Eco­
Home” Pavilion is only case of
entity entered finally into Urban
Best Practice Arca in Shanghai
World Expo, which displays
scientific and technical technology
level of intelligent residential
buildings and will become

9. Solar wall
The heat slowly passes through the
massive wall, and arrives at the inside
surface of the wall several hours later
to provide heat in the evening. The
glazed covering on the outside of the
wall reduces heat loss, and allows
more heat transfer to the inside
space. The vents shown at the top and
bottom of the wall in this diagram are
optional ­­ they allow heat to be
transferred to the living space earlier
in the day than occurs with an
unvented solar wall.

10. Solar heating and solar water heater
The principle of solar water
heater in the building is to
set solar heated apparatus
on the top layer, using the
water pump, water tank,
auxiliary to supply hot
water .The figure shown
above is a flow chart show
the theory of solar water
heater system.

11. Conclusion
• Building energy consumption in China has accounted for
about 45% of the final energy of the society. If the building
can reduce energy consumption by 50% during the process of
using, then it can make a contribution that can reduce 14%
of the final energy of the whole society.
• So solar energy combination building is an inevitable trend in
the future of China. It is also an important developmental
direction in the world .
