Dr. Guy Newsham, FIES Principal Research Officer, National Research Council of Canada
Dr. Newsham completed his Ph.D. in Building Science at Cambridge University in 1990, and joined NRC soon after. He became a Group Leader in 1999, and a Principal Research Officer in the Intelligent Building Operation Program in 2011. Dr. Newsham has led and supported research projects for private and public sector partners on post-occupancy performance of green buildings, office environments, lighting quality and control, sensor networks in buildings, demand-responsive buildings, office equipment energy use, and thermal comfort. He has more than 100 publications related to his research work, which have received numerous international awards. Dr. Newsham is a co-author of the new IESNA/ANSI Recommended Practice for Office Lighting (RP1), and was made an IES Fellow in 2015, and is a Task Group member for Canada’s National Energy Code for Buildings.
Current North American building energy conservation codes address lighting via limits on installed Lighting Power Density (LPD), with certain control technologies prescribed for certain space types. This limits designer choices, makes the benefits of controls difficult to quantify, limits the development of innovative approaches for the next generation of codes, and does not explicitly address peak demand for lighting energy. It is also difficult to translate these control requirements into building simulation models for performance-based compliance. A different approach is an equivalent LPD (eLPD) specification, which is the base LPD modified by the expected reduction in actual power draw due to controls (i.e. not all of the installed LPD will be on, or on at full power, at any one time). Indeed, such an approach is adopted in some international energy codes. In this presentation the approach will be described, and a path to adoption into energy codes will be proposed. A very low eLPD scenario in an open-plan office, leveraging the advanced control possibilities inherent in LED systems and the office of the future (contrasted against incumbent technology), will also be presented.
Explore the equivalent LPD approach to evaluating the effects of lighting controls on energy use and peak demand
Understand how SSL may lower equivalent LPDs in office environments further than incumbent fluorescent technology, and estimate the size of the reduction
Understand lighting sensors’ accuracy
Explore how this technical information could be valuable input to the upgrade of codes and standards.
