Nokia's green Rubik's Cube

Is it a green business to build an environmentally friendly mobile phone?　　In Nokia's view, this is not enough to build a green headquarters to be more thorough. Wen |CBN reporter Ai Yi in mobile phone production to remove bromide, antimony trioxide and chlorinated flame retardant, in time to cut off the "0 load" mobile phone power to reduce energy consumption, support a unified charger, in 85 countries and regions around the world recycling of discarded mobile phones in Nokia's view, these green-related practices are "outdated". Now the company is trying to make green a "common sense" for the entire company.　　In China, "common sense" began in a new building located in the Beijing-Zhuang Economic and technological development zone, which can accommodate thousands of Nokia employees. The "Green Building", which began the creative bidding in July 2005, was an absolutely advanced concept at the time, it requires the overall architecture to comply with a variety of standards on green buildings on a distinctive basis-strict construction according to the American Green Building Association's standards, the building's energy consumption must be reduced to be clearly quantified,　　This is only two years from the expected completion time. "From the green point of view, it is impossible to start the design at the halfway point of the project, it must be Arup and finalized from the first day," says Lu Wenzun, chief architect of the ARUP engineering consultancy, who is responsible for the design of the Nokia Green building. "This is a design process that synchronizes with architectural aesthetics: Nokia and Arup have identified the most popular" glass curtain wall "as the appearance of the entire building, but the biggest trouble with the appearance of the glass curtain wall is that it directly causes indoor temperature rise, especially in summer, when the hot sunlight is projected indoors,　　People can not avoid the air-conditioning temperature to lower some, this is obviously contrary to the original intention of environmental protection. Arup decided to use the double glass curtain wall design for the "green-born" building-from the 2 to 5 floors of the building, the outer layer is a glass curtain wall composed of single-layer glass and non-broken hot profiles, and the interior is a curtain wall composed of insulating glass and broken hot profiles.　　The design of the mystery is: inside and outside the two-layer curtain wall formed a ventilation layer, the two-layer curtain wall spacing of about 1.2 meters to 1.5 meters between the upper and lower ends equipped with wind and exhaust device. In winter, close the ventilation layer at both ends of the inlet and outlet, air in the ventilation layer in the sun under the temperature rise, the formation of a greenhouse, can improve the temperature of the inner layer of glass, reduce the heating costs of buildings.　　In the summer to open the ventilation layer of the air inlet, in the light of the sun to increase the temperature of the ventilation layer of natural buoyancy, forming a bottom-up air flow, take away the heat in the channel, reduce the temperature of the inner glass surface, reduce the cost of refrigeration. The double glazed curtain wall designed to save energy for heating and refrigeration saves 14% of the "air conditioning" energy consumption for the entire building, it also achieved two other effects: The ventilation layer can deliver fresh air to the room, optimize the ventilation quality of the building;　　It is difficult to be compatible in the usual architectural design. Saving "light energy" became anotherA challenging aesthetic proposition-light and light permeability is a necessary element of a commercial building, but it is often the source of enormous energy consumption. "Why not make the whole building more like a cell phone?" Designer Lu Wenzun thought.　　They decided to design a big, transparent skylight across the top of the building-the "sky" is a wide screen of mobile phones, as well as a solution to the entire building's lighting problem. "We consider how to integrate the design of the mobile phone into the design of the building." "Lu Wenzun said. In this way, the entire building because of the "sky" and become transparent, in many cases to save employees have to turn on the lights generated by the power consumption.　　In order to make the building more bright, underneath the "sky" is a "patio" that runs from the bottom to the top, and the offices around it all surround the "patio". In order to allow employees to completely turn the "turn on the Lights" action as an unnecessary problem, they did everything they could: all the offices and the windows of the conference room were all adjacent to the huge patio, so that any self-contained and confined room could "bathe" the sun, which shone directly from the skylight, You can basically meet the needs of the office without having to turn on the lights.　　Such a large "natural lighting" directly brings two benefits: one is to save 1% of the energy for the building, and the second is to allow the "green building" within 97.7% of the area can see the outdoor scenery. Of course, the ideal of natural lighting can not withstand the attack of the night, but Nokia insists on refusing to let the brightly lit scene in the green building.　　In a building that can enjoy the sun's rays almost without a light during the day, the ceiling lamps and air conditioning vents are unusually dense-each employee area's electrical wiring is independent, and no one needs to turn on the whole office lights or air conditioner when working overtime in the dark night when natural air conditioners and natural lighting are all dead. Such a complete and large design system requires demanding construction teams and suppliers. It was not until October 2006 that the construction of the entire building was formally started after a very harsh design.　　Before Christmas at the end of 2007, the first group of employees entered the green building of Nokia China Park. Few people were able to believe that the project could be successfully completed in a year-long construction period, and so fast construction is built on another, more demanding condition--to reduce energy consumption during transportation, most building materials must be procured from within 800 kilometres of Beijing, and extensive use of recycled materials.　　The building is now awarded the LEED (Energy conservation and Environmental Design lead) of the American Green Building Association, the first architectural masterpiece to win the award in China. Does such a huge "green cube" mean huge spending costs? The answer may be yes-the green Park has increased the cost of environmental technology to 2.29% of the total investment in the construction process.　　However, the shuttle workers in the building saved 20% of their energy and 37% of the water. "Just AThe scope of the mobile phone to measure our environmental effectiveness has been a thing of the past, "Nokia Global Executive Vice President Esko Aho said," Our environmental initiatives are making the entire business process and the Office ecological Environment of the overall reduction of carbon emissions, this is the real meaning of our green business. ”
