This report summarizes the findings from a review of a wide range of lighting software tools with a focus on the modeling capabilities of these programs, and in particular the capabilities of these programs in the area of daylighting analysis.
This report contains some general findings of a series of daylight models that was conducted for Building 661 with its existing fenestration systems and with a few small modifications that were made to these systems.
A key objective of GPIC is to design more impactful policies that will affect the market uptake of energy efficient solutions that conform to the overall goal of the GPIC Hub. As such, a macromodeling effort was undertaken to analyze and forecast the regional impact of policies and programs that might be put forward by GPIC’s Policy, Market, and Behavior (PMB) and crosstask researchers. A Policy and Market Macro-Modeling collaborative working group was formed under PMB to create analytical methods and tools to quantify the effects of policies on the adoption of energy conservation measures in commercial buildings. This report describes the methodology developed by the Policy and Market Macro-Modeling working group.
Enhancements to the open-source Daysim daylight analysis software that permit users to model a photosensor control system as it will perform in a real space, considering the directional sensitivity of the photosensor, its mounting position, the space and daylight aperture geometry, window shading configuration; the electric lighting equipment and control zones; exterior obstructions; and site weather conditions.
