Understanding the specifics of sustainable building and determining effective sustainable practices can be confusing. Daylighting analysis is an important component towards creating accurate simulations for sustainable design and visual health. Daylight has been utilized as a design element in buildings throughout history. One of the main reasons for using daylight in recent years is its benefit in reducing energy consumption through its use as a main or secondary illumination source in order to replace the use of electrical lighting. Daylight not only replaces artificial lighting, reducing lighting energy use, but also influences both heating and cooling loads. Planning for daylight therefore involves integrating the perspectives and requirements of various specialties and professionals. Daylighting design starts with the selection of a building site and continues as long as the building is occupied. This paper presents a numerical method based on Dialux to predict daylight factors and daylight uniformity factor into a retrofit office building in order to comply green and sustainability standards requirements.
