What are some examples of sustainable architecture in public buildings?

1. The Bullitt Center in Seattle, USA: The building was designed to be energy efficient, run on renewable energy, and use only non-toxic materials. The Bullitt Center's energy needs are supplied by a 244 kW photovoltaic array on its roof, and it uses water harvested from rain, becoming a zero-energy building.

2. The Seattle Public Library, USA: The library is equipped with energy-efficient lighting, natural ventilation systems and a green roof that helps retain heat and reduce the building's energy consumption. The building also relies on natural light for illumination, reducing the need for artificial lighting.

3. The Chu Hai College of Higher Education campus in Hong Kong:- The campus features a green roof, rainwater harvesting systems, and solar panels to generate renewable energy. The building has achieved Leadership in Energy and Environmental Design (LEED) Gold Certification for its energy-efficient and sustainable design.

4. The Centre for Interactive Research on Sustainability in Vancouver, Canada: The building features a rooftop garden, rainwater harvesting, and uses passive solar design techniques to minimize energy requirements. The facility has achieved several sustainability certifications, including Leadership in Energy and Environmental Design (LEED) Platinum Certification.

5. The One Central Park building in Sydney, Australia: One Central Park is designed to incorporate a range of sustainable and energy-efficient features, such as vertical gardens, high-efficiency lighting, and a co-generation system that generates electricity and heating. This building is one of the most eco-friendly and sustainable buildings in the world and won several awards for its architecture and design.
