We strive to minimise our impacts on the environment by reducing the greenhouse gases we emit and the waste we generate in our operations, as well as the water we consume. For our staff, tenants and customers, we make a strong effort to maintain healthy air quality in our portfolio of buildings.
Hysan Place is an ideal demonstration of how we successfully identify green solutions for our buildings and the surrounding community of Causeway Bay. Hysan Place received Leadership in Energy and Environmental Design standard (LEED) Platinum certification for Core and Shell by the United States Green Building Council, and was the first mixed-use office and vertical mall complex in Greater China to be awarded at this level. The project also received certification at the highest Platinum level under the BEAM Plus standard for new buildings.
At present, more than 45% of Hysan Place’s office space (7 out of 15 floors) is LEED Commercial Interiors Platinum certified, reflecting the efforts of our tenants to incorporate sustainable designs into their offices.
Hysan’s Energy Management Model
Meeting our energy objectives
In 2003, we began managing our energy use by making adjustments to building facilities such as lighting systems, fresh air supply and lifts. The next phase was to install new energy efficient hardware. Upgrading the air-conditioning to a more energy-efficient water-cooled system began in 2006 and was completed in 2012.
Since the opening of Hysan Place in 2012, we have moved into a new phase that emphasises stakeholder engagement as a means of reducing energy consumption, which we will continue under our Energy Management Model.
Energy monitoring and reporting
Hysan achieves improvements in energy consumption through monitoring and reporting. We also have these improvements independently verified, which began with our Corporate Responsibility Report in 2014. Additionally, we are in the process of installing a new energy accounting system with energy meters at the common areas of our commercial buildings to measure and analyse energy consumption within each building. After the installation is completed, we will have a better understanding of our energy usage, which will enable us to meet our targets and further reduce energy waste.
As a result of our efforts to improve the indoor air quality (IAQ) in our buildings’ public areas, we have achieved either “Excellent Class” or “Good Class” standards in the Hong Kong Government’s IAQ Certification Scheme.
Hysan is also a strong supporter of electric vehicles, which help to reduce pollution at street level and improve overall air quality. We have partnered with Tesla Motors to install two Superchargers at Lee Garden One car park, and added more charging bays for other electric vehicles in Lee Garden One, Lee Garden Two and Leighton Centre’s car parks.
Waste and Water Management
As Hysan is the landlord for many food and beverage outlets, we are keen to reduce the amount of food waste generated at these business. In 2015, we collected close to 30 tonnes of food waste from Hysan Place’s food court, Kitchen 11, and some other restaurant tenants within the building. We also joined the Environmental Protection Department and the Greeners Action Food Waste Reduction Programme to publicise the importance of minimising food waste.
Recycling is another initiative we have taken in our malls and office lobbies to reduce waste. We now provide biodegradable plastic bags for umbrellas on rainy days and have installed umbrella dryers to help cut down the use of these bags. Additionally, we have provided extra waste separation bins in malls and the common areas of office buildings for recycling.
In 2015, Hysan was again awarded “Class of Excellence” Wastewi$e labels for all buildings in our portfolio, under the Hong Kong Awards for Environmental Excellence Scheme. In addition, Lee Garden One was honoured as one of “The Top 3 organisations which achieved cumulatively the most number of goals in Wastewi$e Label in 2014”.
Recycling at the Sunning redevelopment project
The demolition of Sunning Plaza and Sunning Court’s superstructure was completed in 2014. Of the close to 40,000 tonnes of construction waste generated, more than 60% (including around 19,000 tonnes of concrete and close to 5,000 tonnes of metal) was recycled. The demolition of the same project’s original basement was completed in 2015, and close to 80% of the demolition waste (including around 3,600 tonnes of concrete and 450 tonnes of metal) were recycled.
We also plan to have building materials with recycled content make up 10% of the total material value of this project.
One of the ways we are conserving water is by reusing the water in our air-conditioning systems for flushing.
We also use recycled water at our Hysan Place Sky Wetland on the 16th floor, which was pure enough for us to obtain a permit from the Government to release it into Victoria Harbour. In addition to its main function of recycling grey water, the Sky Wetland provides a relaxing environment for our office tenants.
