Guoluo booster oxygen activity center obtains three-star green building logo


cooperated in the whole process to complete the three-star green building design consultation of the project

.

Cloud map of temperature at 1.2m of badminton court cloud map of wind speed at 1.2m of badminton court this project is the first important demonstration project in Guoluo Prefecture of Qinghai Province to obtain three-star green building logo

.

The proportion of independently adjustable rooms at the end of heating and air conditioning system in indoor hot and humid environment reaches 100%

.

According to the characteristics of high altitude and cold regions, the project tries to make full use of renewable energy by applying the technology system of near zero energy consumption building and green building technology system, so as to realize the healthy development of pressurization and oxygenation with ultra-low energy consumption Suitable for indoor environment

.

Each main function room has temperature control valve, which can be controlled independently

.

Distribution of sound pressure level at 1.5m height of the site: wind environment at day (left) and night (right) is conducive to outdoor walking and safe travel, meeting the natural ventilation requirements of buildings

.

The openable part can provide good ventilation for the building

.

The waste heat of the oxygen generating equipment is used to obtain higher temperature exhaust air, so as to improve the working condition of the low temperature air source heat pump

.

The project is located in Maqin County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province, with a total land area of 1200 m2 and a total construction area of 669.91 m2

.

·Envelope: the envelope meets the requirements of technical standard for near zero energy buildings (GB / t51350-2019)

.

Transmission and distribution system heating water system hot water circulating pump ﹥ water pump efficiency > 75% fresh air system ﹥ heat recovery fresh air unit ﹥ heat recovery efficiency ≥ 75% air conditioning terminal ﹥ floor heating ﹥ setting temperature control valve application of renewable energy

.

Building energy consumption optimization: the energy consumption of HVAC and lighting in this building is equivalent to 10.2% of the benchmark building, and the energy saving rate is 89.8% compared with the current public building energy saving design standard, which meets the technical requirements of near zero energy consumption building

.

In December 2020, Qinghai ultra-low energy consumption health care center (Guoluo pressurization and oxygenation activity center) successfully passed the green building evaluation and obtained the three-star green building design logo

.

The badminton court in the project belongs to a large space

.

·Natural ventilation: the openable ratio of windows and glass curtain walls is 34.55% and 12%, respectively

.

In the construction process, the near zero energy consumption building technology is adopted, and the solar hot water system is designed on the sloping roof to provide domestic hot water and auxiliary heating for the building

.

·Figure coefficient: compact, only 0.28

.

The evaluation basis is “green building evaluation standard of Qinghai Province” db63 / t1110-2015

.

The wind speed cloud chart of outdoor pedestrian area in winter: < 5m / s, 75% of the openable windows in summer, the wind pressure difference between indoor and outdoor surface is greater than 0.5pa, passive energy saving technical measures · passive solar energy: solar house is set in the south side of the building by using solar energy resources

.

The building has two floors above the ground

.

The construction method of design value of the project is roof K value 0.17350mm expanded polystyrene board exterior wall K value 0.15300mm graphite polystyrene board exterior window K value 1.25lowe + 9Ar + 5lowe + 9Ar + 5 roof transparent part k value 0.86lowe + 16ar + 6 + 16ar + 6lowe active energy saving technical measures equipment energy saving related parameters air conditioning heat source low temperature air source heat pump energy efficiency grade 1; auxiliary heat source includes roof hot air phase change solar collector The heater and the electric heater located in the pipeline auxiliary ensure the operation safety and efficiency in extreme weather

.

The main function rooms are badminton hall, oxygen bar, rest room and supporting rooms

.

With the support and cooperation of the agriculture, animal husbandry and science and Technology Bureau of Guoluo Tibetan Autonomous Prefecture and the construction engineering survey and Design Office of Guoluo Tibetan Autonomous Prefecture, the team of Huanneng Technology Co., Ltd

.

Energy saving effect analysis of various technical strategies the lighting coefficient of main functional rooms of indoor lighting environment buildings meets the requirements of the current national standard “standard for daylighting design of buildings” (GB 50033-2013), and the area proportion reaches more than 81.8%

.

The main function room is equipped with CO2 concentration monitoring system, which is linked with ventilation

.

The successful implementation and demonstration of the project will effectively promote the construction and promotion of green building and ultra-low energy consumption building technology system in western high altitude areas..

.

In order to improve the evaporation temperature of the air source heat pump, the exhaust position of the oxygen generating unit is arranged near the outdoor unit of the air source heat pump, and the exhaust hood is set

.

of China Academy of Building Sciences Co., Ltd

.

Through the simulation and analysis of the environmental noise of the project site, the noise of the site can meet the class 1 standard in the national “environmental quality standard for noise” (gb3096-2008)

.

·Solar energy provides 100% of domestic hot water

.

According to the simulation analysis, the average wind speed in 70% of the activity areas of the badminton court is not more than 0.2m/s, the average temperature is stable at 26 ℃, and the air distribution and temperature are in a reasonable range
