Key Environmental Performance Indicators in 2003

Reducing Footprint

We are seeking every opportunity to minimize the environmental impact of our products and activities. Through the implementation of sustainable design concepts and sustainable construction practices on site, we carefully plan the integration and compatibility of our projects with the surrounding environment, the conservation and efficient use of land, energy and material resources. In our office, we implement the best practices of green office management and adopt the principle of avoid, reduce, reuse/recycle and use of recycled products for our daily operation.

Energy Efficiency

We take the lead in implementing energy efficient technologies in building services installations. Through the use of water-cooled air-conditioning systems, high efficiency chillers, heat pumps, thermal wheels, high performance lighting systems and demand control systems etc., we achieved an estimated annual saving of 108,000 MWh of energy in 2003. We adopt the “overall energy approach” in building design to critically consider the energy dynamic of buildings so as to achieve good quality built environment while ensuring sustainable use of energy. In 2003, we successfully registered 177 installations under the Energy Efficiency Registration Scheme for Buildings launched by EMSD.

Clean and Renewable Energy

The installation of building integrated photovoltaic (BIPV) system in Science Park Phase I Project is a showcase for implementing renewable energy technology in buildings. It is projected that the series of BIPV installations can save approximately 200 MWh of electricity consumption annually. Other projects completed in 2003 utilizing solar energy for water heating are: Sha Tau Kok Fire Station and Police Dog Unit & Force Search Unit at Sha Ling.

In the project Hong Kong International Wetland Park Phase II, we take the initiative to install the first geothermal heat pump air-conditioning system and utilize the wetland around as a source of heat and a heat sink. Through 468 pairs of vertical geothermal pipe heat exchanger buried in the wetland, heated water from water-cooled refrigeration plants and cool water from water source heat pump are circulated in a common condenser water loop to exchange their energy directly. The system operates at a high efficiency, substantial low running cost and without direct rejection of waste heat into the atmosphere.

Sustainable Building Design

To encourage our staff as well as consultants to commit themselves to environmentally sustainable design, we organize Sustainable Design Awards Competition annually as a recognition of the contribution made by project teams in the sustainable design. We also select projects to go through an environmental performance assessment using the HK-BEAM (Hong Kong Building Environmental Assessment Method). In 2003, the Photonics Centre (Building 4a) and the Wireless Centre (Building 4b) of Science Park have achieved the highest HK-BEAM rating of “Excellent” in terms of environmental design and building management provisions.

In 2003, projects awarded with Certificates of Merit in the Sustainable Design Awards were:

	Re-provisioning of Diamond Hill Crematorium
	Stanley Complex
	Building 4 in Science Park at Pak Shek Kok
	Building 5 in Science Park at Pak Shek Kok
	Primary School in Ma Wan
	Primary School in Sze Mei Street, San Po Kong

Sustainable Construction

In 2003, five contractors had won awards in the Green Contractor Award Scheme. They were:

Gold Award
	Gammon Skanska Limited for the Fire Station with Ambulance Depot and Police Post at Penny's Bay
Silver Awards
	Chevalier (Construction) Co. Ltd. for the International Wetland Park and Visitor Centre at Tin Shui Wai - Phase II Works
	Shui On Construction Co. Ltd. for the Castle Peak Hospital Redevelopment - Phase II Stage 2
Bronze Awards
	Free Form Construction Co. Ltd. for the Water Sports Centre at Stanley Main Beach
	Hip Hing Construction Co. Ltd. for the Design and Construction of the N.T. South Regional Police Headquarters and Operational Base at Tsuen Wan.

Sustainable Procurement

Inclusion of requirements for environmentally friendly materials in project specifications has proofed to be an effective way of promoting environmental sustainability. Our General Specification for Building 2003 Edition has been published. In addition to the requirement on the use of timber from certified sustainable forests, the use of environmental friendly carpet, recycled aggregates in concrete and low VOC paint are incorporated.

Construction & Demolition Materials

The reduction of C&D wastes continued to be a priority of the Department. The requirements for 'waste management plan' and the implementation of the 'trip ticket system (TTS)' are specified in the contract documents and site works are closely monitored by our site supervisory staff. We issue internal guidelines to tighten the control over the disposal of C&D waste. In 2003, we handled 93,654 nos. of trip tickets from 179 ArchSD's sites and we disposed 474,357 m³ C&D materials to the Public Fill and 107,126 tonnes C&D wastes to Landfill.

However, we regret that despite our effort in tightening the control, in May 2003 two of our contractors failed to comply with the trip ticket system and had made unauthorized dumping from two of our sites to the Conservation Area at Shuen Wan Marshes. In these incidents, the consultants and the contractors were seriously warned and were required to take immediate action to tighten up the control of the trip ticket system, and at the same time to reinstate the affected land immediately. The corrective actions were then checked and accepted by all concerned parties. We had also reminded all project staff to monitor closely the implementation of the trip ticket system, and carry out thorough checking of the trip ticket records on sites.

Energy Efficiency Awards Scheme

To support the commitment of the Government to cut energy consumption in government buildings, we have implemented a series of energy saving measures in our offices. For example, the installation of timers to automatically switch off non-emergency lighting, exhaust fans and power sockets after office hours, rescheduling the running time of the air-conditioning plants and lift services, the installation of T5 lighting system with electronic ballast and motion sensor during retrofit programmes and the installation of photo sensor to control carpark lighting. In 2003, we achieved a 3% reduction in the total electricity consumption in APB Centre. We also participated in the first Hong Kong Awards for Energy Efficiency and Conservation in Government with the aim to benchmark our performance and to share experience with colleagues in other departments.
