The IES supports research projects that are directed to advance lighting knowledge in the areas of light and visual processes, light and human health, lighting quality, and the integration of lighting in the holistic built environment. Programs targeted toward funding research efforts in these areas are being formulated now, with the additional criteria that such research be done in collaboration with co-funders and that the knowledge gained will advance the understanding of lighting and IES Standards.

Collaborating Funders: ASHRAE, BC Hydro, IALD

Principal Investigator: AES Engineering

Objectives: This project supports the development of the Lighting Power Density (LPD) limits in the ANSI/ASHRAE/IES 90.1 Standard that form a significant part of the basis for most of the building energy code lighting requirements across the United States. Project tasks will support the work of the 90.1 Lighting Subcommittee (LSC) by providing computer modeling that parallels the current Excel models used in Lighting Power Density (LPD) development. Computer modeling will help improve the accuracy and applicability of the LPD values which in turn will strengthen the effectiveness of the Standard and other nationally applied energy codes and standards.
