Although LEED certification for Green Buildings has been widely acknowledged in Chinese real estate market, so far no residential project has met the Platinum criteria, the highest standards possible in the system. To achieve Platinum is highly demanding in requirements for materials, environment, water, and energy conservation. The whole construction process will be evaluated by experts from the LEED-recognised associate, and the certification will be finally awarded 2 years after the evaluation by homeowners is submitted. Wanliu House is full devoted to setting a precedent.
Note: LEED is short for Leadership in Energy and Environmental Design, a rating system developed by the U.S. Green Building Council (USGBC). LEED recognises performance in five key areas: sustainable site and environment, water savings, energy efficiency, materials and resources, and indoor environmental quality. It provides the most authoritative third-party verification. The total score of LEED certification is 110 points, and buildings can qualify for four levels: Certified (40–49 points), Silver (50–59 points), Gold (60–79 points), and Platinum (80 points and above).
SINOBO Land introduced the most advanced air purification system in the world to Wanliu House. The integration of technologies guarantees that 99% of PM1.0 will be filtered out, whilst the ventilation system maintains constant temperature and humidity at the most comfortable level.
Honeywell High Efficiency Particulate Air-filters
are installed in front of the ventilation system for preliminary filtering, and absorb suspended particles smaller than PM 1.0. Particles are charged in the circulation generated between motherboard and earth electrode, and then collected. Thus, air is cleaned.
STANDARD Ceramic Air-humidifiers
are installed at the freshair outlets. With humidity controlled, physical comfort is greatly boosted even in dry seasons for north China.
PHI light ioniser air purification technology from RGF, USA
Through the endeavours of 29 years, RFG Environmental Group summarised its work in the most advanced PHI air purification technology.
PHI cleasing factors, through the attraction between positive and negtive electric charges, succesfully settle PM10, PM2.5, and even smaller particles, and completely destroy the chemical bond of volatile poisonous gases, in which case, formaldehyde and benzene are broken down into CO2 and H2O. Meanwhile, the technology damages the genetic matters in germs and bacteria, and hence all harmful elements are removed from the air. Compared with traditional air cleaning technology, which is negative, PHI ligh ioniser air purifiers bring about complete dustruction of four major pollution sources in the air. In the concerning environment of Beijing, Wanliu House is dedicated to providing the cleanest air for its residents.
Water, the source of all life forms, is the foremost concern for SINOBO Land in its construction. The filter, which is fixed on every kitchen pipe, includes PP cotton, activated carbon, and a reverse osmosis membrane. The five-step drinking water purification process removes such heavy metal ions as mercury until direct drinking water standards are maintained. SINOBO Land holds water safety as one of the most valued qualities of a residence, and strives to provide the purest water by our standards.
Benchmarked against LEED Platinum verification, Wanliu House has carried out an extensive exploration. Rooftop solar panels are installed to save and convert sunlight to solar energy for underground lighting. Additionally, optimsed designs, including large-sized windowpanes maximise the utilization of sunlight. Imported weight-bearing framework is used to prevent deformation of windows. Another example is the underground garages equipped with light wells to allow sunlight in. Ever-present sunlight and vegetation bring to life a properly lighted tranquility.
A quiet life depends on overall environment to avoid external interruption. The demand for noise insulation for Wanliu House does not stop at the indoor level, and all-round planning is available. Theatre-grade sound insulation has been achieved in the construction of Wanliu House, and quiet is finally gained despite the boisterous neighbourhood.
● With 200-mm aerated concrete blocks, plastic-extruded boards for thermal insulation, and hand-made clay bricks from Netherlands, the exterior wall is 400mm in thickness; heat insulation/preservation and noise reduction are substantially improved.
● Moreover, 100-mm gas sand blocks and 50-mm air layers are implemented in lifts and shafts; soundproof rock wool is utilised where the shafts go through floorslabs to reduce drainage noise.
● Doors and windows are equipped with three layers of double-silver LOW-E glass with level-three sound insulation and level-seven gas tightness.
● Separating floorslabs are inlaid with Laticrete rubber insulation pads, with a distinction in thickness between 5mm for soft space (e.g. wooden floors) and 7mm for hard space (e.g. stone materials).
lectronic security systems are installed at the entrances of the residential perimeter, individual buildings, the garage, lobbies, lifts, and all residential units. Infrared sensors are applied to perimeter security and curtain control, and around-the-clock smart monitoring is in use for the safety and privacy of occupants. Introduction of smart furniture provides multiple controls over lights, curtains, the visual system, and air conditioning. The remote control app can be downloaded to Apple or Android devices, and one-touch smart settings make easy operations possible for seniors and children.
