There is a trend in modern construction industry, that is, to try to protect
the whole environment. Architects try to reduce the harmful effects on
building residents caused by external pollution, and at the same time try to
avoid using fuel indiscriminately, thus causing adverse effects on the
environment. This kind of building is called "green" building or "environmental
protection" building, and its main goal is to reduce the ever-increasing energy
cost. The "Times Square building" in New York is the first generation of green
buildings. In fact, it was launched as the first green skyscraper in the United
States. Its owners have made conscious choices to improve the environmental
quality of employees and tenants, and have also reduced the operating costs of
the building. The air filter room outside the building supplies the filtered air
for the lower part of the building, which is the first set of filter used to
remove particulate matter in the outdoor air. These filters have been installed
here for less than two weeks, but they have changed from the original bright
color to black. These filters can filter out 85% of the pollutants outside,
and their filtering effect is more than twice as good as that of other skyscrapers
in New York. This is also the first skyscraper equipped with solar panels in North
America. In France and other parts of Europe, solar energy technology has been
paid more attention, mainly because energy costs have remained high for a long
time. Solar panels are installed on windows or walls. They capture the direct or
diffuse light of the sun and turn light energy into electric energy. This
system can reduce energy costs by 15% to 20%. Electricity also comes from two
groups of huge fuel cells. They produce a mixture of hydrogen and oxygen that
can form electric energy, which is sufficient to meet the energy needs of the
building at night. In addition to the standard lighting requirements, New York
City also formulated local regulations for the purpose of tourism, requiring
that all the buildings facing New York Times Square should be lit up at night,
this is the reason why the square is so bright. The mixture of hydrogen and
oxygen in the fuel cell will not produce any pollution. Natural gas is used for
heating and air conditioning in this building, which is a wise choice compared
with electricity, because there will be huge loss of electricity in the process
of transferring from power plant to skyscraper. Another building is rising from
the ground in batri Park, which is located by the Hudson River. When this
building welcomed the first group of tenants, it was one of the most advanced
residential buildings in the American continent. The water recovered from the
building and the collected rainwater will be used to irrigate the roof garden,
so it is much cooler than the standard asphalt roof. The recycled water can
also be used in the refrigeration system of the building. The building will
also be equipped with solar panels, and the location will enable it to obtain
energy to the maximum extent. In New York, most of them can normally act on
solar panels. Not only in summer, we can generate 80% of the electricity needed
by this building only through it. At present, it is increasingly focusing on
lighting as a source of energy conservation with practical application value.
This technology has been extensively studied in Europe, and the cost of energy
spent in Europe can be called astronomical figures!
