In response to climate change and global warming, we set the following measures for the planning, design and construction of our projects, in mitigating carbon emissions and adapting to the impacts of extreme climate events:
8.1 A project shall put the following climate-resilient consideration into account:
- Identify climate impacts for the project’s region;
- Incorporate possible impacts into performance goals for the building project and the neighborhood;
- Refine regional impacts to smaller scale; anticipate how climate changes are likely to manifest in the local environment, present design team with a range of possible scenarios;
- Choose strategies that enable the project to achieve and maintain performance goals, under all possible futures, for the expected life of the project.
8.2 The cooling towers will provide “free-cooling” during the Spring and Fall transition periods as well as during the winter time for Office and Retail spaces. (Applicable subject to availability of the cooling tower system).
8.3 High △ T is applied to both chiller water and cooling water system to reduce pump energy.
8.4 The chilled water system for the office and shopping mall operates with Variable Water Flow control, which reduces water pumping energy during variable cooling load conditions.
8.5 The building elevator adopts a regenerative energy recovery system, which can convert the potential energy of the elevator in operation (such as full load descending and no load ascending) into electric energy. This energy can be fed back to the power substation to reduce the project’s energy consumption. This measure will only be adopted when the speed of the elevator is above 2.0m/s.
8.6 Air conditioning systems (including Primary Air Units and Air Handling Units, etc.) are equipped with secondary air filters to improve IndoorAir Quality and mitigate the effects of poor outdoor air quality.
8.7 10% of total parking spaces of a project shall be provided for EV-charging stations to help reduce use of fossil fuels and improve local air quality.
8.8 Environmental- friendly refrigerants are used to minimize global warming and ozone depletion.
8.9 High-efficiency LED lighting helps to reduce energy consumption.
