Recently, the 2020 Luban Prize of China Construction Engineering was announced, and the demonstration project of Weifang fengluyuan, a passive ultra-low energy consumption building in our province, won the Luban Prize
. 
Passive ultra-low energy consumption building is a kind of building which provides comfortable indoor environment by adopting envelope structure with higher thermal insulation performance and air tightness performance, as well as technologies such as fresh air heat recovery and renewable energy
.
It took the lead in Germany and other European developed countries in the 1980s and 1990s, and has been more and more widely promoted in recent years
.
Compared with traditional buildings, passive ultra-low energy consumption buildings have the advantages of high efficiency and energy saving, constant and controllable indoor air quality and temperature and humidity
.
In cooperation with the German Energy Agency, our province started the construction of ultra-low energy consumption building demonstration in 2014, successively formulated and released the energy-saving design standards, construction technical guidelines, acceptance technical points of passive ultra-low energy consumption residential buildings, established and improved the technical standard system, strengthened the design and construction personnel training, and led the development of passive ultra-low energy consumption buildings
.
At present, 59 passive ultra-low energy consumption building demonstration projects with a building area of 1.123 million square meters have been established in the province
.
A number of demonstration projects have passed the acceptance of the German Energy Agency, and the energy efficiency has reached the level of similar buildings in Germany
.
Fengluyuan passive residential project in Weifang was approved as a provincial passive ultra-low energy consumption green building demonstration project in 2016
.
It is the largest and highest passive ultra-low energy consumption hardbound residential project in cold areas in China, and has been completed and put into use
.
Five highlight technologies are adopted in the project: first, sunshine, ventilation and structural thermal bridge are fully considered in the planning and architectural design, with compact layout and no obvious structural thermal bridge
.
Second, the external wall insulation material is made of 220 mm thick graphite polystyrene board, the doors and windows are made of 90 series multi cavity plastic steel profiles, the glass is made of three glass two cavity double Low-E argon filled hollow fireproof glass, and the wall of heating space and non heating space is made of 10 mm thick vacuum insulation board with class a combustion performance, which can effectively meet the needs of fire prevention and increasing indoor use space
.
Third, each household is equipped with a high-efficiency heat recovery fresh air air conditioner, the heat recovery efficiency is more than 75%, equipped with intelligent control system to realize the intelligent control of temperature and humidity, PM2.5 and CO2 concentration in each room, and can implement remote control through mobile phone app
.
Fourthly, the sound insulation pad is added between the surface layer and the structural layer to fully reduce the impact sound transmission of the floor, and the sound insulation effect is 5dB (a) lower than the control standard value required by the specification
.
Fifth, BIM Technology is fully used in engineering design, civil construction, mechanical and electrical construction and decoration construction, which plays an important role in improving efficiency, saving cost and shortening construction period
.
Fengluyuan project of Weifang won Luban Prize, which will play a positive role in promoting the construction of passive ultra-low energy consumption buildings in our province and leading the development of commercial housing towards green, low energy consumption and high quality
