The development and application of a localised metric for estimating daylighting potential in floor plate

Abstract

In this study, daylight and its role in designing office floor layouts, given its notable effect on work environment productivity and well-being have been considered. In this research, existing daylight metrics, like sUDI, have been challenged and both employees' preferences and the geographical characteristics of an office floor layout have been re-developed developing a localized metric that includes. Methodology of this research is quantitative and it is basically has been done through comparison of before and after changes that specific indices have created. First, local features have been derived based on the climatic and cultural conditions of a particular ecosystem (land, country, or region). Spotted Geometric Potential for Daylighting (sGPD), which includes ideal locations in terms of daylighting quality for building elements such as furniture or stairs has been specified. As such, GPD includes employee preferences and geographical specifications to form complex and asymmetric plans. This study builds on existing research by improving dynamic daylight metrics (such as sUDI) based on geometrical features and users' preferences to provide a new tool for designing an office floorplate. As a case study, the optimum dimensions of a sample L-shape plan in Tehran have been measured by a GPD 2.12. It also includes the priorities of employees for having a maximum view of the outside by 77%.
