• The design is based on requirements of 80% of IBS and 80% of Green Building Index.
• A green building concept is introduced which is taken up to save water, energy and material.
• The landscaping and the exterior look of the Toll Plaza are designed in such a way that
the trespassing light is eliminated by plants and shaded area.
• Rain water from the roof of the building is harvested to supplement the conventional water supply. The natural light is maximized for the intermediate floors to minimize the usage of electricity. High efficiency windows and insulation in walls, ceilings and floors are used for the benefit of better temperature control.

v. Flora & Fauna Monitoring
• Marine flora and fauna are monitored throughout the construction phase to reduce demands and complaints from fishermen and fish farmers who ostensibly incurred losses as a result of the bridge construction.
• To ensure the aquatic life is not effected by the construction of Second Penang Bridge, Fanli Marine & Consultancy Ptd. Ltd. (Fanli) is appointed by JKSB as an Independent Consultant to monitor the Fisheries Impact Assessment (FIA) for this project. Fanli had earlier completed the base line study in 2007 for the Fisheries Department.
Environmental Responsibility
Overview Fisheries Industry in Penang There are 17 fishing villages on the island and 14
fishing landing point on the main land. In 2007, marine fisheries catch in Penang
amounted to 37,774 tonnes worth RM 218.9 million.
The industry provides livelihood to nearly 3,193 fulltime fishermen.

vi. Habitat Creation
Research by Lund University in Sweden has discovered that the Oresund Bridge connecting Denmark and Sweden has improved the Marine Environment in 10 years since it was built.
In the Second Penang Bridge, aquatic life such as
algae and fishes are found around the driven piles.
They become food for fish like the Longfin Bannerfish (Heniochus acumiratus), Rock Grouper (Epinephelus fasciatomaculosus) and White Cheeked Monocle Bream (Scolopsis vosmeri) and the local “udang lipan” (Stomatopod Crustacean).
It is evident that the construction of Second Penang Bridge does not affect the marine environment of the surrounding area.
