Demonstration project | The first AAA precast near-zero energy consumption swimming pool in China will be put into use

Located in the east of Hongji Road, the west of Diaoyutai Road, and the north of Park Avenue, the swimming pool is built by Fengxi Group Investment Company.

The main and passive buildings lead Xinfengshang natatorium to adhere to the design concept of “passive technology priority, active technology optimization”, and skillfully use the building heating system, cast sandwich insulation composite board system, active sunshade system and other technologies to ensure the constant temperature and comfort of the natatorium.

In addition, the venues will implement standardized all-in-one card management to realize the common use of multiple venues in the new city, and meet the diversified needs of consumers for admission, storage and consumption.

In addition, through rainwater recycling, reclaimed water recycling, swimming pool water recycling, etc., we can improve the reuse rate of water resources and achieve energy conservation and water saving.

In order to ensure the cleanness of the skylight, zero water consumption and self-cleaning can be achieved through the roof skylight self-cleaning circulation system.

In winter, in combination with the light-transmitting inclined roof lighting system, the solar room heat collection effect is used to store energy and collect heat to ensure that the sun covers the eight swimming lanes of the swimming pool on the winter solstice, maximize the storage of solar energy, and significantly improve the indoor environment comfort of the swimming pool.

According to the Evaluation Standard for Assembled Buildings in Shaanxi Province, the assembly rate of the natatorium reached 91.77%, reaching the AAA standard.

Recently, the swimming pool project of Fengxi New Town in Xixian New Area was awarded the certificate of “near zero energy consumption building” at the design stage, marking the birth of the first AAA-level precast near zero energy consumption swimming pool in China.

Especially in summer, the natural ventilation rate can reach more than 19 times/hour, which can eliminate 100% indoor residual heat and humidity and toxic chlorine, and can also prevent excessive direct sunlight through electric sunshades.

The medium-deep geothermal energy non-interference clean heating technology solves the heat source problems of 42% winter radiation heating, 80% domestic hot water, and 100% pool water heating in the swimming center by drilling heat from 2000-3000m underground and using geothermal energy cascade utilization and intelligent control technology to achieve the low-carbon goal of heating and hot water system.

The intelligent integrated enabling technology model swimming pool uses Internet intelligent perception technology to store energy and enable intelligent operation.

Medium-deep geothermal energy non-interference clean heating system thin film photovoltaic power generation system thin film photovoltaic power generation system determines the innovative integration scheme of building and thin film photovoltaic through shadow analysis of the natatorium.

This is also another effort of Fengxi New City to practice the concept of green development and actively explore the realization path of “carbon peak and carbon neutralization”.

In the design process of Xixian Fengxi No.

It is estimated that the natatorium can save about 550000 yuan of electricity, about 329 tons of standard coal and about 879 tons of carbon dioxide emissions every year.

Renewable energy helps carbon neutral natatorium adopt technologies such as medium-deep geothermal energy non-interference clean heating, solar photovoltaic building integration, etc.

1 Primary School and Fengxi New City Experimental School, Fengxi New City incorporated the concept of green and low carbon into it, highlighting the application of renewable energy, resource recycling, intelligent management, etc.

Designed and built according to the star-level building standard, the AAA-level precast swimming pool is designed and built according to the national three-star green building standard, AAA-level precast building standard, and two-star health building standard.

From sponge city to clean heating, from smart pipe gallery to green buildings, Fengxi New Town has always been committed to continuous innovation genes and providing “green development code” for the city.

Through data collection and big data analysis, the management efficiency and service level are greatly improved.

It is an important supporting part of the Xixian Fengxi First Primary School and Fengxi Experimental School under construction, with a total construction area of about 10600 square meters, and consists of four swimming pools, including a 50-meter standard long pool, a 25-meter standard short pool, a children’s play pool, and a hot water pool.

The integrated and integrated high efficiency thin film photovoltaic module on the roof of the natatorium is 4200 square meters, achieving an annual power generation of about 630000 kWh, which is more than 30% higher than the conventional photovoltaic system.

to maximize the use of renewable energy to meet energy demand and solve energy consumption problems.

Through the national evaluation of near-zero energy consumption buildings, the comprehensive energy saving rate of the project reached 91.64%, the energy saving rate of the building body reached 46.49%, and the utilization rate of renewable energy reached 84.38%, with remarkable energy saving effect, It was rated as “near zero energy consumption building” by China Building Energy Conservation Association.

The project sets up an intelligent integrated management platform that integrates energy consumption monitoring, intelligent services, water temperature and water quality perception and control, and integrates multiple functions such as air monitoring, energy management, water temperature perception, and water bacteria monitoring.

In spring, summer and autumn, natural ventilation measures should be fully used to achieve ventilation, dehumidification and heat removal in the venue.
