Effect of fixed horizontal louver shading devices on thermal performance of building by

摘要

Buildings in most countries around the world require large amounts of energy both for cooling and heating. In fact cooling loads due to solar gains represent about half of global cooling loads for residential as well as non-residential buildings. While solar gains through windows contribute largely to these loads, any method of decreasing these gains though shad- ing should be applied with caution,. Since a balance is required; decreasing cooling loads by shading may increase heating loads drastically and vice versa.
