Daylighting Multipliers - Increasing Daylight Harvesting Efficiency | HSW

Description:

This session will explore the role that daylighting multipliers are used when trying to increase the efficiency of daylighting or daylight harvesting in a building, such as, light shelves, manufactured glazing, and material specification. Furthermore, we will explore the rate of return, the ranges of efficiency, and appropriate uses between daylighting strategies and multipliers.

HSW Justification: Daylighting is an important renewable resource that buildings can utilize to reduce a lighting systems kWh as well as improving building occupants mental health. For this lecture we divide the benefits of daylight into two categories; Energy benefits and Non-Energy Benefits. We emphasize that non energy benefits can be coupled with energy benefits to help convince clients to utilize daylighting as resource for their buildings. Such as, improving mental well being through connecting to nature by having a view and daylight window while simultaneously reducing energy use through the year.

Learning Objective 1: 
Participants will learn the differences between daylighting strategies and daylight harvesting as it relates to IECC 2012, IECC 2015, and LEED V4.
Learning Objective 2: 
Participants will learn the appropriate uses for daylighting multipliers, such as, light shelves, manufactured glazing, material specification, and secondary daylight strategies as it relates to the context of the built environment.
Learning Objective 3: 
Participants will learn the appropriate uses for daylighting multipliers, such as, light shelves, manufactured glazing, material specification, and secondary daylight strategies for increasing efficiency of uniform illumination and the annual kWh load.
Learning Objective 4: 
Participants will have an understanding that not all strategies that are implemented will have a full range of desired efficiency or uniform illumination, but rather, a layering of daylight strategies and multipliers is required to achieve these goals.
