Chapter 4 - Pollution Prevention and Control Noise

GREENING NOISE BARRIERS

Noise barriers were traditionally a double-edged benefit. On the one hand, they cut down traffic noise; on the other hand, they could be visually intrusive. The Government therefore has put much effort in recent years into improving their attractiveness and other environmental impacts.

Input starts at the planning stage, when there is the opportunity to ensure environmentally-sensible barrier designs and green materials are adopted as far as possible. Barrier designs today are expected to be compatible with the surrounding environment and not disrupt the harmony of the living area for residents. Examples of green and aesthetic barriers in Hong Kong include transparent barrier panels and green walls with embedded plants and climbers to improve the overall landscape design.

Contractors also have to meet pollution control requirements and be proactive in using energy efficiently and procuring environmentally-friendly materials. An example of this is lighting. Contractors are encouraged to replace battery-operated lanterns with solar energy lanterns to reduce chemical waste. They are also encouraged to use Quality Powered Mechanical Equipment under the administrative labelling system promoted by EPD.
