"In addition to high space utilization rate, green buildings can also save energy, water, land and materials to a large extent." Lin Zhizhi introduced that at present, 13 projects in Xiamen have won this honor.
According to the green building action, Xiamen has started to implement energy-saving reconstruction of buildings in an all-round way since this year. "New buildings in cities and towns should be subject to mandatory energy conservation standards Public buildings It needs to be evaluated and then transformed. " Lin Zhizhi said that by the end of next year, 2 million square meters of green buildings will be built in the city. At the same time, the existing large public buildings and office buildings of public institutions with an area of more than 20000 square meters will also be green transformed. "The first thing to do is to diagnose the energy efficiency of the equipment systems in these buildings." Lin Zhizhi said that according to the preliminary investigation, there are more than 300 large buildings in this part. At present, energy efficiency diagnosis has started. "Every building category has energy efficiency limits, and if they exceed the limits, they will be transformed." Lin Zhizhi said that in the first half of this year, 10 plots that have completed bidding, auction and listing have been built according to the green building standards, There are 5 commercial residences, and Wuyuanwan Hospital is also in it, which will become the "green hospital" of.
Green building action will also make building power generation more intelligent in the future. Lin Zhizhi revealed that at present, the new intelligent solar photovoltaic building project has been successfully completed. "Most buildings and residential buildings need to convert AC power into DC power through electrical appliances, which requires a lot of energy."
Lin Zhizhi said that, in contrast, solar photovoltaic buildings can convert light energy into AC power directly through the solar panels on the roof, and connect it to the power grid, eliminating intermediate conversion links. At present, three solar photovoltaic buildings, namely, the East Energy Engineering Building, the South Building and the North Building, have been completed and accepted for use in the Xiang'an Campus of Xiamen University. "This project is the first in China, especially suitable for islands and high mountains." Lin Zhizhi said that from the current assessment, solar photovoltaic buildings will gradually be promoted in Xiamen in the future.
"Industrialization" construction reduces dust and noise. With more and more construction projects inside and outside the island, dust and noise generated by large and small construction sites are increasingly disturbing the citizens. Lin Zhizhi said that this green building action will also implement the "industrialization" transformation of the city's building model.
Specifically, through modern and unified manufacturing, transportation, installation and scientific management, the current decentralized and inefficient "manual production" is replaced by a standardized large-scale industrial production mode. "The new mode saves time and labor. Some reinforcement structures can be completed in the factory in advance and then transported to the site, which will reduce dust and noise pollution." Some formwork and scaffolding used in the site can also be prepared in advance.
