CIC Zero Carbon Building, Hong Kong, SUNPIPE® and WINDCATCHER®

CIC Zero Carbon Building, Hong Kong, SUNPIPE® and WINDCATCHER®

ZCB is the first zero carbon building in Hong Kong and was selected as a finalist in the World Architecture News sustainable building of the year award for 2014.  The concept of “Zero/Low-carbon” Building involved the integrated environmental design on one hand, such as heat island mitigation, reduction of solar heat gain through building envelope, natural ventilation and daylighting optimization strategies for low energy consumption, and on the other hand, the use of renewable energy and state-of-the-art clean technologies for on-site energy generation.  Over the course of the year, a building is said to achieve “zero-carbon emissions” when it harvests sufficient non-fossil fuel energy to account for its carbon footprint fossil fuel use.

Being one of the landmark projects in the industry, all the products applied in this project were selected and approved for HK BEAM Plus Platinum green award for building.  This certificate is granted by the Hong Kong Green Building Council.   

Sunpipe and Windcatcher played an important role in energy saving and reducing the impact on the environment.  The objective of the building is to provide an example of what a sustainable building can be like in an urban environment.  By providing natural light to the building, occupants can enjoy a healthier working space with a reduced need to use electric lights throughout the day, thereby reducing the building’s carbon footprint. 

Assistant Manager - Technical Services, ZCB - CIC Secretariat said “The Sunpipe brings daylight deeper into the office space/exhibition space, whilst the Windcatcher brings cooler fresh air into the building interior and exhausts hot air from within the building.  The Sunpipe has worked well and it can be quite bright, visitors are often surprised and impressed that it is natural light.  The quality of the light is most impressive as it is warm in colour.  The colour of the light is warm compared to cooler whiter daylight that illuminates the ECB eco-office on the northern side of the building (with a large glazing area).  I think that staff generally prefer natural light and would be more productive”

There are many benefits to installing a natural ventilation system; by using wind pressure and the natural stack effect of thermal buoyancy, natural ventilation does not use any fossil fuelled energy but relies on harnessing wind power and the thermal rise of warm air to be used in a controlled and sophisticated way.

It’s also healthier; natural ventilation brings in a steady supply of fresh air into the building, topping up the oxygen level, whilst at the same time expelling stale air to atmosphere using the natural buoyancy of thermal forces.
