The development is a commercial building at 470-472 Hennessy Road, Hong Kong. It consists of 22 commercial floors (G/F-1/F, 3/F-6/F, 8/F-21/F,23/F-24/F) and 3 floors for E&M (2/F, 7/F & 22/F).

Green Features

Site Aspects

  • Obtrusive light from exterior lighting meets the specified performance for the environmental zone in which the building development is located. 
  • Roof material that meets the Solar Reflectance Index (SRI) of 82 or vegetation roof covering 1000% of the total roof.
  • Designs for which the access to daylight of neighbouring sensitive buildings is maintained to the prescribed level.

Materials Aspects

  • 100% of all timber and composite timber products used in the project are from sustainable sources/recycled timber.

  • The use of materials manufactured locally within 800 km from the site, which contribute at least 10% of all building materials used in the project. 

  • At least 88.44% of demolition waste is recycled.

Energy Use

  • A reduction in the annual energy consumption by 27.32%

  • Energy monitoring of various categories of building services installations.

Water Use

  • An estimated annual saving of 56.74%. 

  • A reduction in annual sewage volumes by 48.4%.

Indoor Environmental Quality

  • Outdoor ventilation rate that exceeds ASHRAE 62.1:2007 [1] requirements by at least 30%.

  • 84.85% of the floor area in all normally occupied spaces is adequately lit with an average daylight factor of 1%.

  • An adequate ventilation system for rooms/areas where significant indoor pollution sources are generated.

Innovations and Additions

  • Twin Tanks are provided.

  • 100% of all timber and composite timber products used in the project are from sustainable sources/recycled timber.

  • Roof material that meets the Solar Reflectance Index (SRI) of 82 or vegetation roof covering 100% of the total roof.

Story

Inspired by the global movement of Advancing Net Zero, this project is dedicated to embracing a "green" and more sustainable future.

 

It goes beyond mere construction, prioritizing the enhancement of health and well-being for building users. Recognizing that a sustainable building should minimize its carbon footprint while providing a nurturing environment, innovative design elements were incorporated. These elements promote natural light, optimize air quality, and ensure convenient access for persons with disabilities within the building.

 

Several measures were implemented to achieve these goals. Firstly, 84.85% of the floor area in all normally occupied spaces is adequately lit, meeting an average daylight factor of 1%. Furthermore, the outdoor ventilation rate exceeds the requirements set by ASHRAE 62.1:2007 by at least 30%. Additionally, an effective ventilation system is in place for rooms or areas where significant indoor pollution sources are generated. To ensure indoor air quality, measurements for all IAQ parameters, including CO, NO2, O3, RSP, VOC, HCHO, and Rn, are conducted.

 

In terms of accessibility, three convenient access points for persons with disabilities are provided. These include clear access routes with a width of not less than 1500mm, the provision of unisex toilets on each commercial floor, and unobstructed wheelchair turning spaces measuring 1500mm x 1500mm in front of accessible lift car doors on each floor.

 

To achieve sustainability, a wide range of green products has been sourced and incorporated into the project. For instance, 100% of all timber and composite timber products used are from sustainable sources or recycled timber. The roof material meets the Solar Reflectance Index (SRI) of 82 or is covered entirely with vegetation. Refrigerants used have values lower than the specified threshold for their combined contribution to ozone depletion and global warming potentials. Additionally, the building fabric and services avoid the use of ozone-depleting substances in their manufacture, composition, or use. Moreover, a minimum of 10% of all building materials used in the project are manufactured locally within 800 km from the site.

 

By implementing these measures, this project aims to set a new standard for sustainability, showcasing the importance of environmentally conscious choices in construction and design. It strives to create a greener future while providing a safe, healthy, and inclusive space for its occupants.
