Prescriptive Requirements for Vertical Fenestrations as per ECBC 2017

For all climatic zones, vertical fenestration compliance requirements for all three incremental energy efficiency levels, i.e. ECBC, ECBC+, and SuperECBC, shall comply with the following: (a) Maximum allowable Window Wall Ratio (WWR) is 40% (applicable to buildings showing compliance using the Prescriptive Method, including Building Envelope Trade-off Method) (b) Minimum allowable Visual Light Transmittance (VLT) […]

Daylighting Compliance for ECBC

What is Daylighting? Daylighting is the controlled admission of natural light, direct sunlight, and diffused-skylight into a building to reduce electric lighting and saving energy. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and productive environment for building occupants, while reducing as […]

U-Value Prescriptive requirements for Roofs & walls as per ECBC 2017

U-value Thermal transmittance (U value) is the heat transmission in unit time through unit area of a material or construction and the boundary air films, induced by unit temperature difference between the environments on either side.Unit of U value is W/m2.K. U value for the wall/roof/glazing indicates its ability to transfer heat through conduction. Following […]

Energy Conservation Building Code (ECBC)

Introduction The purpose of the Energy Conservation Building Code (Code) is to provide minimum requirements for the energy-efficient design and construction of buildings. The Code also provides two additional sets of incremental requirements for buildings to achieve enhanced levels of energy efficiency that go beyond the minimum requirements. The Code is applicable to buildings or […]
