Abstract
Tall buildings are considered as a great consumer of energy which utilized huge amount of resources and materials; produce massive volumes of waste discharge into the environment and more often called as unsustainable buildings. Building materials such as steel and cement with high intensities of embodied energy are required to create the skeletal framework and lay the foundation for their long lasting structures. The growing global pressure to reduce carbon footprint and concerns for creating sustainable habitats, have also greatly ignited the quest to delve for innovative solutions and emerging trends in tall building designs. This paper discusses environmental sustainability in tall buildings with special reference to the application of renewable energy technologies. Further the paper also validates the application of renewable energy technologies by two detailed case study namely Bahrain World Trade Center, Bahrain and The Pearl River Tower, Guangzhou.
Highlights
There was a perception until now that the tall buildings are highly energy consumers with little regard for sustainable architecture and more often considered as unsustainable. These large scale tall buildings were regarded as mega guzzlers which consume a lot of energy, utilizes huge amount of resources and materials and produces massive volume of waste discharge into the environment
Recently there has been a paradigm shift with a new generation of high rise buildings that have been designed with reference to sustainable architecture especially towards renewable sources of energy
A tall building is regarded as a building which is greater than 20 storeys
Summary
There was a perception until now that the tall buildings are highly energy consumers with little regard for sustainable architecture and more often considered as unsustainable. These large scale tall buildings were regarded as mega guzzlers which consume a lot of energy, utilizes huge amount of resources and materials and produces massive volume of waste discharge into the environment. The onus has shifted to the built environment to ensure that new structures reduce energy consumption and increase efficiency through the use of renewable energy sources, innovative and green construction materials and technologies, recycling and waste management systems etc. This paper discusses sustainability in tall buildings with special reference to the application of renewable energy in tall buildings
