Daylighting Systems (SCCER - FEEB&D)

Research in the "Future Energy Efficient Building & Districts" (FEEB&D) focus of "Swiss Competence Centre for Energy Research (SCCER) includes optimal day- and electric lighting to reduce the energy consumption in non-residential buildings by 70-80%.

Status:

Completed

Period:

01.01.2014 - 31.12.2016

Overview

The focus of the Daylighting task is to provide novel simulation tools for planers.This task will develop advanced simulation tools for daylighting systems. This will include compression methods for simulating complex fenestration systems for which transmission properties are characterized using a Bidirectional Transmission Density Function (BTDF data) from a novel bidirectional gonio-photometer. These improvements to simulation software can foster their dissemination among practitioners (lighting industry, energy consultants and architects).
