Description:
Energy efficiency through daylighting can only be realized when electric lights are dimmed or switched. This workshop provides information about daylight harvesting control strategies and technologies, focusing on current approaches, main issues and emerging technologies (e.g., automatic calibration/commissioning, use of multiple sensors), including use of open and closed loop sensing, photosensor characteristics, control algorithms, installation and commissioning.
Speaker Bio:
In a career spanning over 25 years, David Weigand has worked in the lighting consulting, contracting, commercial construction and utility industries. His experience in the utility industry extends to establishing energy incentive programs for Portland General Electric, Pacific Power, Washington Water Power and the Bonneville Power Administration. In the private industry, he has worked as the manager of lighting and electrical standards for Starbucks Coffee Chain where he developed standards for energy efficiency, while creating unique lighted environments that improved customer satisfaction. His experience also includes positions as a specification/contractor sales representative for Harry L. Stearns, Inc., Senior Engineer for A&C Enercom, Inc. and Electrical Designer for Interface Engineering Company.
Weigand has been active with state and national standards organizations on writing new energy codes and has served as a review consultant for California’s Title 24 development and ASHRAE/IES90.1 standard. His articles on energy management and the effect of lighting on worker productivity have appeared in magazines such as LD+A, and the Journal of Commerce. For the last 3 years, he has served as a panelist and speaker at LightFair as well as other trade shows and industry conferences, and lead classes on architectural lighting design and energy management at Portland State University, Oregon State University and the University of Oregon. He holds a BS in Electrical Engineering from Portland State University. In his new post at Leviton, Weigand will focus on developing new market opportunities with national accounts (businesses, contractors and utility companies) for energy management lighting controls. These products include Leviton’s line of occupancy sensors, whole-building energy management controls and daylight harvesting systems.
Leviton’s comprehensive line of lighting management systems offers state-of-the-art energy management solutions for commercial, theatrical and architectural lighting applications.
