net positive energy buildings: a sustainable approach toward future architecture

The largest energy consumers of energy are the building sectors worldwide, contributing towards environmental degradation and carbon emission. As need for sustainable development is increasing rapidly, the concept of net positive energy buildings [NPEBs] emerged as advanced approach in green architecture. Through the integration of energy systems and efficient design strategies, the buildings are designed to consume less energy over a year. This research paper traverses the principles and design approaches of net positive energy buildings. It considers the passive design techniques, energy efficient systems and the use of renewable energy sources such as solar power. Real world applications and effectiveness are also explored through different and selected case studies. Additionally, this paper highlights the execution of the concepts of net positive energy, where the role of climate and economic factors plays a very important role in Indian context. This result indicates proper planning, technology and awareness, net positive energy buildings can significantly reduce dependence on energy sources and contributes to sustainable future.
