Owner approach of sustainability

In the aspect of green building design, design and build according to the green building concept, reasonably choose the green ecological technology suitable for the residential building, and reach the three star green building standard from the aspects of land saving, energy saving, water saving, material saving, indoor environmental quality, improvement and innovation.

 The main aspect of Germany's DGNB certification is the inclusion of the ecological, economic and socio-cultural impacts of green buildings. It is the importance of promoting the sustainability of the three pillars of society to the same level of second-generation green buildings. (sustainable building) certification system; including the cost calculation of the whole life cycle of the building, can effectively assess the control of construction costs and investment risks; the building performance evaluation as the core rather than the presence or absence of measures as the standard, and for the owners and designers In the initial stage of building positioning and design, it provides a wide range of operational approaches for achieving specific objectives; it is a dynamic assessment of the participating buildings, showing the pros and cons of different technical systems and indicator requirements, and providing comprehensive application performance evaluation for participating buildings. Established a standard system based on the high level of quality of the German construction industry system; according to the principles of the EU standard system, it can be applied to different countries' climate and economic environment, and has strong flexibility.

In addition, the project uses rainwater recovery system and landscape water body to reduce the rainwater runoff of the site, using high-performance enclosure structure to create a comfortable indoor environment; using ground source heat pump system and capillary end and displacement fresh air to achieve temperature and humidity independence At the same time of regulation, the indoor constant temperature and humidity constant oxygen is maintained; the indoor air quality is improved; the energy-saving appliances such as energy-saving appliances, energy-saving lamps and energy-saving elevators are adopted, and the energy conservation is achieved by adopting these measures.

  • The water consumption of this project is domestic water, green sprinkling, road square flushing, basement flushing, etc. The maximum daily water consumption of this project is 153.48 m3/d, and the maximum hourly water consumption is 6.4 m3/h. Sprinkler irrigation is adopted for greening irrigation. The sanitary appliances and fittings of this project adopt water-saving products of grade 1 water use efficiency. The toilet flushes with 2.9L/4.2L two-stage flushing water tank; the nozzle flow rate is 0.07L/s, and the shower flow rate is 0.078L/s. Appropriate material and pipeline connection mode are adopted to effectively reduce leakage of pipeline network. Set up grading water meter. The project collects rainwater in the site, and after physical and chemical treatment, it is used for road sprinkling, greening irrigation, water supplement and so on. The project collects rainwater in the site, and after physical and chemical treatment, it is used for road sprinkling, greening irrigation, water supplement and so on.
    This project uses high-end drinking water treatment system and household water purification equipment to effectively remove suspended solids and particulate matter in water, so that families can drink healthy water sources.

Indoor Air quality

    Measured indoor CO2 concentration (mg/m3): 1071

    Indoor formaldehyde concentration (mg / m3): 0.031

    Indoor TVOC test concentration (mg/m3): 0.25

    Indoor benzene concentration (mg / m3): 0.013

    Indoor PM2.5 test concentration (ug/m3): 10

    This project uses replacement fresh air system, the air purification mode is primary filtration, intermediate effect filter (G4), two-stage static electricity and bag medium efficiency filter (F9), PM2.5 purification efficiency > 90%, to ensure indoor air cleaning. Replacement fresh air system: fresh air is fed from the lower part of the room, filling the whole room with very low speed (no sense of blowing) and temperature slightly below the indoor temperature. Residents and other indoor thermal loads heat the fresh air and produce rising air. The warm air generated in this way flows into the nose with fresh air, and takes away the sweat and exhaust gas and other turbid gases from the human body. Finally, it reaches the top of the room and discharges from the exhaust holes, and forms a fresh air lake in the room.

    In the application of indoor environmental protection coatings, the suppliers of decoration materials should be strictly screened and the VOC content of core building materials (such as sheets, coatings, adhesives, etc.) should be controlled according to "zero formaldehyde".


    Average indoor temperature in January: 21 degrees   Average indoor humidity: 45%

    Average indoor temperature in July:26 degrees    Average indoor humidity: 60%

    The project adopts ground source heat pump system, capillary radiation air conditioning system and displacement fresh air system.

    Ground source heat pump system: Through a closed pipeline (called loop) buried 80-100 metres underground, Soil is used as an energy reservoir for heat extraction and heat dissipation of ground source heat pump units, and heating/refrigerating circulating water generates heat and cooling energy. By importing a small amount of high-quality energy (electricity, etc.), energy conversion can be realized, and the optimal effect of refrigeration and heating can be achieved.

    Capillary network radiation air conditioning system: With water as the medium, heat (cold) is gently transmitted to the room through radiation. It can realize household control, save about 30% - 50% energy than conventional air conditioning combined with ground source heat pump, and ensure the balance and comfort of room temperature in the home. The temperature is maintained at 20 - 26 ℃ for the whole year. The indoor temperature is almost the same, and the deviation is less than 2 ℃.

    Replacement fresh air system: It has functions of humidification, dehumidification and haze removal (multi-stage filtering, filtering hair, mosquitoes, etc., and filtering efficiency of PM2.5 up to 90%). The air with the most suitable temperature is exported through the fresh air outlet, and the fresh air is sent down and back to form an orderly air circulation. Without opening windows, pure air can be input uninterruptedly, and the indoor humidity effect of about 30-70% can be achieved.

    The weight sound insulation of the air acoustics meter for the outer windows of residential space is more than 30dB. Facing the entrance of the aisle, the weight of the air acoustic meter is more than 25dB. The elevator shaft is not adjacent to the bedroom and living room. Sound insulation measures should be adopted when adjacent to other living spaces.

    Through the comprehensive upgrading of the exterior wall enclosure, door and window system and indoor decoration, controlling sound insulation performance of floor, partition wall and doors and windows, and select low noise equipment, do a good job of air duct sealing, so that the indoor noise of residential buildings is lower than the national standard.

    Using the same layer drainage system, water seal pipe fittings sharing the same layer drainage system of high-density polyethylene HDPE is used instead of many P-bends and S-bends. The overall structure is reasonable. So it is not easy to jam, and easy to clean up, dredge, with international first-line brand pipes, the noise may be controlled at a lower level, to create a quiet living environment.
