Lighting design can reduce energy use by ensuring that each area of a space is lighted appropriately. Architectural design can maximize the use of daylighting. Below are some of the design-related completed projects and ongoing programs at the LRC.

Lighting Patterns for Homes
Lighting Patterns for Homes was created to help homeowners, contractors and builders choose the right light bulbs, fixtures and controls to maximize energy savings, calculate lighting costs and achieve lighting effects to meet a wide range of needs in their homes.This site also shows how to design safe, healthy lighting for aging adults. It helps homeowners and others navigate the increasing number of lighting options in today's marketplace and allows them to see how various options will actually look by viewing photo-realistic illustrations created by 3-D modeling software.

Residential Lighting Video Series
The LRC has produced a series of brief videos that guide builders, contractors, and homeowners in providing energy efficient, high quality lighting in residences. The video series, produced in 2015, provides an accessible overview of a number of topics important to residential lighting, including an overview of efficient lighting; cautions when upgrading lighting; light bulbs and fixtures; upgrading incandescent bulbs; economic calculations; and lighting tips for kitchens, living rooms, bedrooms, home offices, and bathrooms. The videos complement the LRC’s Lighting Patterns for Homes website, and viewers are guided to the most relevant portion of that website.

Case Studies of Energy-efficient Lighting
Case studies of efficient lighting from the Demonstration and Evaluation of Lighting Technologies and Applications (DELTA) program, including residential, commerical, industrial, and outdoor sites.

Daylight Dividends
Daylight Dividends is a multi-year joint research program facilitating the widespread implementation of daylight in buildings. The "dividends" include human comfort and performance and energy savings. Daylight Dividends is run by the Lighting Research Center on behalf of the project sponsors. The program began in 2003 and continues today to provide resources to building professionals.

Patterns to Daylight Schools
This publication presents model designs for implementing daylighting into school classrooms, corridors, and gymnasiums. With emphasis on human health impact and other daylight metrics, this book compares cost, comfort, visual environment, and energy use among well-known daylighting techniques. Conceptual daylight approaches are offered for the three most common spaces in schools: classrooms, corridors, and gymnasiums. The designs and technical analyses are distilled to visual presentations for architects and school administrators. A “daylighting dashboard” is introduced, a graphic method to quickly compare the patterns.

DesignWorks
Lighting designers can help you achieve better lighting that uses less energy. The LRC's lighting design program, DesignWorks, provides cutting-edge lighting design solutions, effectively pairing advanced research with dynamic design concepts.

Outdoor Lighting Pattern Book
This hardcover book, published in 1996, presents many lighting possibilties for typical outdoor residential, commercial, institutional, industrial, and public spaces, including walkways and areas adjoining apartment houses, alleys, quick-stop shopping, pedestrian malls, city business districts, office parks, parking garages, loading docks, school yards, playgrounds, public parks, and waterfront walks. The lighting suggestions are provided through a series of "patterns" or model lighting designs. Although the lighting technology has advanced since the book's publication, the lighting designs themselves remain relevant. The book has been used as the basis for waterfront renovations in older urban areas, and won an International Award of Achievement from the Society for Technical Communication.

Mesopic Street Lighting
The LRC developed the unified photometry system, which determines equivalent visual performance levels under photopic and mesopic light levels. This report describes a case study of energy savings achieved by designing streetlighting with the unified photometry system.
