Conclusions

Spatial

The Shanghai Tower achieves a vertical lifestyle. Assorted services facilities and scientific designed leisure area can reduce the usage of elevators, which is quite environmental-friendly.

This building is well connected with the train station and adjacent buildings, so it is quite convenient for people to approach it.

Thermal

In Shanghai, glass curtain wall is affected by solar radiation seriously. Plus a high height, indoor insolation distribution does not only influence the air-conditioning load, but also indoor thermal environment. By using IES <VE> and Star-CCM+, design measures are adjusted according to the results, which are exhausting air at the neutral plane with 26° and setting up an air outlet on the top. Through these methods, the temperature distribution in the atrium is well controlled.

Indoor Air Quality

Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria), or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality. Before the project started, an air quality test was made and the Protection and control measures in construction stage were also applied. In the construction process, the choice of materials plays a key role for IAQ, too. The last but not least, good ventilation, the indoor green plants as well as the air purifying equipments contribute to the good Indoor Air Quality.

Visual

The indoor visual environment is necessary to meet the requirements of human physical, physiological, psychological, ergonomics andaesthetics. With the more advanced lighting technology, the use of lighting is also more widely. Light provides more active performance factors for indoor space environment, enhancing the quality of the indoor space. Besides the nature dayling, the material is also affects the indoor visual environment because of the different reflectivity and refractive index. Good visual enverionment could give people comfortable atmosphere for working and living and improve the quality of life and work efficiency. Shanghai Tower sets an awesome example for the whole world in this aspect.

The spaces between the two fagade layers create nine atrium sky gardens. Much like plazas and civic squares in traditional cities, the public sky atria offer spaces within Shanghai Tower for interaction and community gathering space with restaurants, cafis, coffee shops and convenience stores, as well as lush landscaping throughout.Fully one third of the site will be green space with landscaping that cools the site.

On the ground level, retail and event spaces, in tandem with abundant entrances on the site and a subway station under the building, continue the physical and visual connections between the tower and the city.

Shanghai Tower will have the world's fastest lifts, with the Mitsubishi-designed, double-height cabs whisking building occupants and visitors skyward at 40 mph using innovative technologies designed specifically for the tower.

Sustainability is at the core of Shanghai Tower's design. The facade's taper, texture and asymmetry work in partnership to reduce wind loads on the building by 24 percent, offering a $58million savings in overall building materials.

The tower's outer skin also insulates the building, reducing energy use for heating and cooling. The tower's spiraling parapet collects rainwater, which is used for the tower's heating and air conditioning systems.

Wind turbines located directly beneath the parapet generate on-site power for the upper floors of the building, with a 2,130kW natural gas-fired cogeneration system on site providing electricity and heat energy to the lower floors.

Overall, Shanghai Tower's sustainable strategies will reduce the building's carbon footprint by 34,000 metric tons per year; and the tower gets LEED Gold certification from the U.S. Green Building Council and the China Green Building Three Star rating.

Acoustic

Some evaluation issues for indoor acoustic environment like, reverberation time; sound pressure level; audibility are lacking measurement data to prove good acoustic condition. although, these can be moniterd after completed construction.

In the design process, the project adopted various protection measures in acoustic condition, adopting low noise mechanical and electronic equipment; taking control measures to the external environment that unaffected to surroundings. The road traffic noise environmental noises outside the building project exceed the standard (daytime, night 1~6dB (A) 1~8dB (A)), but after the insulation of glass curtain wall, noise level of the office and hotel department can meet the design requirements.

Building integrity

As for building materials' degradation and movement problem, locally sourced materials with a high-recycled content have been used where possible. The team seeks out building materials that are harvested and manufactured within an 800- kilometer radius of the site. Local sourcing of products is sustainable because it reduces transportation-related environmental impacts and boosts local economy.

In order to reach requirement in fire safety, the experienced simulations have been done to further verifing the correctness of the air-supplement vent arranged in the inner wall of the atrium.
