At the end of March, the Qingdao Housing Provident Fund Management Center issued the “Notice on Adjusting the City’s Housing Provident Fund Loan Policy.” Among them, in addition to adjusting the maximum amount of provident fund loans to 800,000 yuan, it also mentioned that policies will be adopted to support the purchase of high-quality housing and green building housing. Among them, residents who purchase new high-quality housing in Qingdao or meet the current green building evaluation When applying for a housing provident fund loan for newly built commercial housing with a standard one-star rating or above, the loan amount will be increased by 20%.

In fact, since last year, “good houses” have been constantly mentioned. As an important representative form of “good houses”, green building housing has received more and more policy support, leading the new trend of ecological living. So, what is green building? Today, let’s learn about green buildings together.

Green buildings already have standards

What is a green building? In fact, the competent authorities have already defined it. In April 2021, the Shandong Provincial Department of Housing and Urban-Rural Development and the Provincial Market Supervision and Administration Bureau jointly approved the release of the newly revised “Green Building Design Standards”. Taking “high-quality green building” as the main content and highlighting the five major performances of “safety and durability”, “healthy and comfortable”, “convenience of life”, “resource conservation” and “environmentally livable”, the technical requirements and design methods of green building design have been revised and improved. Green buildings are also defined in great detail.

First of all, Shandong Province’s green building evaluation standards have strict regulations on the selection and use of building materials. Building materials are required to comply with relevant national environmental protection standards, and renewable resources and recycled materials should be used as much as possible to reduce the consumption of natural resources and reduce the impact on the environment during the construction process. Secondly, the green building evaluation standards put forward requirements for the building design and construction process. The building design should fully consider the local climate characteristics and adopt energy-saving, thermal insulation, heat insulation and other technical means to reduce energy consumption. During the construction process, it is required to reduce the generation of construction waste, rationally utilize resources, and reduce damage to the environment. In addition, Shandong Province’s green building evaluation standards also put forward requirements for the operation and maintenance of buildings. Buildings should design reasonable energy-saving systems, including the use of renewable energy sources such as solar energy and geothermal energy, to reduce reliance on traditional energy sources. The maintenance and management of buildings should be scientific and reasonable to extend the service life of buildings and reduce waste of resources.

Green buildings make living more comfortable

As the country’s first green city construction and development pilot, Qingdao has integrated the concepts of green development and smart construction into every corner of urban renewal. When green buildings are implemented on an individual basis, what impact will they have on our lives?

In fact, as early as 2011, the Tiantai City Phase 6 Tiantai Mei Cube project had a green technology brand of “high comfort, low energy consumption”. Replacement of fresh air and other technologies create a “technological residence with constant temperature and humidity 365 days a year, without air conditioning and heating.” At present, Qingdao’s property market is ushering in a green revolution. More and more development projects are committed to the practice of green buildings, and residential projects that comply with green building concepts are constantly being launched. At the same time, home buyers are increasingly aware of the value of green homes and regard them as one of the important factors in choosing a home.

Uncle Liu, who lives in Julin New Village, told reporters that his family implemented energy-saving wall renovations during the renovation of the old community in 2022. The biggest change is that my home is warmer in winter. “In the past, you had to wear a thin down jacket at home, but now you only need to wear a woolen vest, which can raise the temperature by 5 degrees Celsius.” Uncle Liu told reporters. In 2022, the city will add 24.7 million square meters of green buildings and promote 137,000 square meters of ultra-low-energy buildings. In particular, Qingdao has listed energy-saving and thermal renovation of existing residential buildings as a practical matter for the municipal government for seven consecutive years. It has completed a total of 41 million square meters of energy-saving and thermal renovation of existing residential buildings, saving 200,000 tons of standard coal annually and reducing emissions. 550,000 tons of carbon dioxide.

Of course, it is not just the renovation of old residential areas, the latest indoor temperature control technology is also used in the Fushanhouyi real estate. “It is to lay ultra-fine circulating water pipes on the wall and use geothermal technology to flow cold water in summer and hot water in winter. Use this method to control the indoor constant temperature.” The technical staff of the community told reporters that because they all use geothermal resources, they can Greatly reduce dependence on air conditioning and heating. In addition, in recent years, energy-saving equipment such as three-chamber insulating glass and solar water heaters have also appeared in large numbers in new home decoration lists, making life more comfortable and reducing energy consumption.

What does the future of green buildings look like?

Driven by the dual-carbon development goals, green buildings are increasingly valued by competent authorities and recognized by users. At present, what are the new development trends of green energy-saving buildings? We might as well go to the Sino-German Industrial Park to take a look. The Hongshi Xiujing Hotel, which has just been put into operation, has been officially opened a few days ago. Through the application of passive ultra-low energy consumption building technology and the implementation of green three-star building standards, it has become a comprehensive energy-saving rate that can reach approximately 52.7% are eco-hotels. By applying energy-saving technologies such as photothermal, high-efficiency exterior insulation systems, high-performance exterior doors and windows, ground source heat pumps, and fresh air heat recovery systems, and taking measures such as thermal break bridges and electric louver exterior shading, they built Qingdao Hongshi Xiujing Hotel into a passive, ultra-low energy Consume buildings. At present, Hongshi Xiujing Hotel can achieve constant temperature, constant oxygen, constant humidity, and constant silence. The indoor temperature is as low as 20°C in winter and as high as 25°C in summer.

“Rationally arrange the living space, encourage large bays and small depths, and create flexible living space designs so that residents can renovate and reuse them later.” Ni Jiangbo, vice president of the China Building Energy Conservation Association, said when talking about future green buildings There is such a proposal. Of course, more than just a building or a house, green buildings require larger-scale planning. On September 7, 2023, the final evaluation of Qingdao’s green city construction and development pilot work successfully passed the review of the expert group. Qingdao has fully completed all the tasks set in the pilot plan, achieved the pilot goals, and passed the scientific and systematic “1+5+1” evaluation indicator system, including carbon emissions, green buildings, green communities, green neighborhoods, green urban areas, and green villages. and seven dimensions of green finance, forming eight aspects of experience that can be replicated and promoted nationwide.

Green community, listen to what designers have to say

Xia Lei (pictured above) is the project manager and senior architectural design engineer of Qingdao Urban Architectural Design Institute. She has been committed to building her own unique “design ecological path”, striving to break through the boundaries and barriers of traditional design links, insisting on making green buildings and letting buildings have “life”. The residential projects she designed on Dongyue Middle Road North and Lianghe Road West in the West Coast New Area won the Qingdao Excellent Architectural Design Award.

“When I won this award, I was thinking that as urban land is a non-renewable resource, we must not only make full use of the land, tap its potential, but also effectively allocate resources and achieve an overall high-quality community environment and development economic benefits. A win-win situation.” In the end, she used the original terrain to build a large strip-shaped green space, combined with the existing green space resources to build a large public open green space, and created a rich ecological landscape system according to the changes in the site’s topography. At the same time, the natural terrain and vegetation will be effectively protected and rationally utilized during the construction process to establish effective ecological effects and rich visual spatial forms for the community’s outdoor environment. Make full use of the core resource landscape to create an elegant lifestyle and create a core green space in the community to make the environment quiet and quiet with green grass. It can be said that “tranquility in the bustling world, nature in the city, bustling when you go out, and tranquility when you enter.”

“Advocate green buildings and make buildings alive.” Xia Lei told reporters that this has a huge relationship with the concept of green buildings she advocates. In addition, in the super high-rise Guoxin Technology Building project she participated in the design, she also created a forest landscape inside the plot and used the new “three-dimensional park” model to perfectly integrate with the surrounding communities.
