This document discusses the benefits of daylighting design in buildings. It notes that daylighting can increase student and worker productivity by up to 20% and 50%, respectively, and reduce energy costs by 30%+. Daylighting is better for human, economic, and environmental performance. The document then describes several daylighting prototypes for a school that were modeled, showing reductions in energy use and costs. It advocates for an integrated design approach to daylighting to maximize benefits.
Program Level: This is a level 200 program. Intended for individuals familiar with green building principles and practices.
Who Should Come: Individuals involved in the building design, construction and renovation industries, especially those who are interested in optimizing daylighting to reduce energy consumption and enhance occupant comfort and productivity.
"When properly designed and effectively integrated with the electric lighting system, daylighting can offer significant energy savings by offsetting a portion of the electric lighting load. A related benefit is the reduction in cooling capacity and use by lowering a significant component of internal gains. In addition to energy savings, daylighting generally improves occupant satisfaction and comfort. Windows also provide visual relief, a contact with nature, time orientation, the possibility of ventilation, and emergency egress."

A luminaire is defined in Article 100 as “a complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps and ballast (where applicable), and to connect the lamps to the power supply.” Since luminaires (lighting fixtures) were not previously defined before the 2002 NEC, this new definition is meant to cover all aspects of a lighting unit, including the lamps that actually provide the illumination, as well as internal and external parts necessary for the proper operation of the unit.

Light as an important architectural element in contemporary architecture..A short dissertation /presentation by..... Atul Pathak ,BIT MESRA..Department of Architecture
In this white paper we focus on the electric lighting of houses and their immediate surroundings; however, this is not a course in lighting technology. There are already enough informative books and specific training courses on that subject. Instead we provide insight into various aspects of interior and exterior lighting and lighting controls that are important for the design of a lighting system. The ultimate aim is to design a lighting system which ensures that users or occupants feel comfortable during all activities and experience adequate lighting comfort. We gladly leave the detailed calculations to the experts at lighting dealers and wholesalers.
This white paper is the first of a series of thematic white papers dealing with various aspects of electrical installations in houses, flats and residential units. They are intended for architects, designers, specification writers, decision makers, installers and students.
Creating energy-efficient buildings can be a large task, but following these tips and tricks about daylighting can make the job easier. Learn about everything from window placement to skylights and how they can help you achieve a more efficient building.

This workshop will provide a general overview of daylighting strategies in commercial buildings, emphasizing the importance of integrating daylighting with energy-efficient lighting systems and controls. We will also explore how daylighting is achieved from a LEED standpoint and how CA's Title 24 addresses daylighting.
Sandy Houck, LC, LEED AP of Brummitt Energy Associates will present the benefits of daylighting strategies for your commercial project.
Last February 17, 2012, the 2nd IIEE-CRCSA Technical Seminar kicked off with a good response from the members and non-members with the participation of more than 100 who showed-up at the White Palace Hotel, Riyadh, Saudi Arabia. Seminar title was “Basics of Indoor Lighting using DIALux”. The seminar was conducted by Engr. Michael T. Santiago, a Lighting Application & Design Engineer from Saudi Lighting Company. The participants were awed by his DIALux 4.10 software demonstration specially when he imported a room layout from AutoCad drawing and applied the lighting calculation on it which later provided a very nice colored 3-D drawing of the room. A continuation of this seminar which is “Basics of Outdoor Lighting” will be presented on the incoming 14th Midyear Convention.

INTERIOR LIGHTING DESIGN A STUDENT'S GUIDEno suhaila
This guide on lighting design is intended for students who have no prior knowledge of lighting and also for those who are experienced but would like to bring themselves up to date with developments in lamp and luminaire design, modern design theory, European Standards and the CIBSE code for Interior Lighting 1994.
It develops the basic principles of lighting science but then goes on to provide a modern design perspective for both artificial lighting and day lighting which will be useful to experienced designers.
Effect of Natural Light Glare on Passive Design in Malaysian Government Offic...drboon
Starting in 2009 the government of Malaysia has stipulated that all government offices building to be incorporated with sustainable design features. However, the questions on the design still ponders and requires a research especially in the adoption of passive design strategies whether they have met the occupant visual comfort and taken all the consideration on the penetration of daylight. Qualitative survey has been conducted on the occupant’s perception toward visual comfort in selected working space and by using DAYSIM simulation to obtain an explicit comparison on the effect of glare inside the room to verify the survey analysis done earlier. Finding from the survey showed that 61.2% of the respondents agreed that there is glare from the windows of the office and 52.2% respondent agreed that internal shading reduced the discomfort glare from the windows. The research will be useful as basic recommendation on the indoor comfort environment especially for the occupant visual comfort in designing a government office building.
24 percent of commercial energy end-use is used for lighting purposes, a very big percentage of which is utilized for lighting buildings during the daytime.
Our idea is to use optical fibers to bring concentrated day-light into buildings so that significant savings can be made in electricity cost as well as CO2 emissions.
This presentation was done as part of the assignments for Venture-lab, Technology Ventures 2012 course.
Lighting accounts for about 41% of the energy consumption. Crescent/Stonco and its affiliated Philips lighting companies are first to bring you the latest in lighting new technology. Induction and LED sources are fast becoming the luminaires of choice for energy savings, low maintenance and long-term sustainability.
The primary focus of this webinar relates to real-time tracking of investments in lighting upgrades to show high actual rates of return.
BSL and JCC have been working together on proving the case for LED Lighting upgrades with the University of Cambridge.
We will present the case for LED lighting and tools which can be used to demonstrate live investment tracking using BSL's LED investment ticker tool. We will show the investment tracking tools in action on JCC's website.
The webinar is presented by Building Sustainability's George Bartley and JCC's Ian Tucker.
Our Solatube Daylighting Systems are known as Tubular Daylighting Devices (TDDs). They capture sunlight using a rooftop dome, then transfer it indoors through a reflective tube that runs from the roof to the ceiling. From there, the light is evenly dispersed into the interior space using a diffuser.
When it comes to lighting, we believe that access to daylight is a human right. Studies have shown that people exposed to natural light are more productive, achieve a better sense of well-being, and are more positive. Until recently, the technology to deliver natural light to interior spaces like closets, bathrooms, offices and corridors simply didn’t exist. That’s no longer the case.
