Integrated Design Sustainable Skyscraper: The Design Factors, Sustainability Credentials

There is no doubt that integration of appropriate vernacular and sustainable strategies can reduce the high-rise building’s energy consumption significantly.

As Bachman listed the types of integration,[1] Performance integration means to share the functions of the two elements without actually combining the pieces. For instance in a direct-gain passive solar heating system, the floor of the sunlit space can share the thermal work of the envelope and the mechanical heating systems by providing thermal mass and storage.

If the HVAC and the facade systems are well integrated, the operating and initial cost will be reduced and also the occupants comfort will be improved. When decisively considering environmental performative design, very little to almost no data is available to compare the improvements compared to the conventional designs.

The design of high-performance tall buildings requires the integration of components and systems. It is crucial to holistically combine the strategies to achieve high- performance energy goals. There are four independent steps to lead into the net zero energy introduced by SOM:

  • • Reduction: The first step to a high-performance building is to find the possibilities to reduce the energy consumption. Most of the energy goes into HVAC and lighting systems. The reduction strategies need to target those areas.
  • • Integration: The second step is to include strategies to take advantages of passive resources and integrate them in building envelopes.
  • • Reclamation: The third step is to harvest the energy that has been once used in the buildings and recover it to be reused.
  • • Production: This step incorporates the technology to produce renewable energies efficiently.

The concept of environmental performative high-rise building should include a critical overview of its actual performance. The claims of performative design should be based on the comparison of the building’s real performance to the conventional model.

This chapter discusses the two case studies in regard to integration of the systems with special emphasis on sustainable buildings. Many projects can demonstrate the ideas and principles behind performative design. Two of those are analyzed and introduced below. First is the Manitoba hydro tower by KPMB Architect completed in 2009 and the second is the One Bryant Park by COOKFOX Architect in 2010. The first is an example of integration of passive strategies while the second incorporates site-renewable energy generation.
