Assessment of thermal loading in energy-efficient buildings: parametric review on the window design aspects

Abstract

Today, the main challenge to world energy policies is to complete the energy demands of society more sustainably without polluting the environment. The application of renewable energy sources is an alternative solution, but they are less efficient compared to conventional sources. The efficient utilization of energy ensuring the minimum losses from the system is an effective way. In this context, properly designed buildings can contribute in minimizing the overall energy demands of society. Generally, window systems are considered a critical part of a building with significantly poor thermal performance. Those must be designed carefully for the building to be energy efficient. The present work takes an opportunity to review several design parameters (window) affecting the annual energy consumption statistics (in terms of cooling and heating loads) for the buildings.
