Daylighting Performance Metrics Explained

daylightARCHITECTURAL LIGHTING recently published an article about annual daylighting performance metrics–Spatial Daylight Autonomy and Annual Sunlight Exposure–adopted by the IES.

These metrics enable designers to quantify and evaluate the success of daylighted spaces.

Product Monday: Stream by Prudential

streamPrudential Lighting’s Stream Series creates an uninterrupted, uniform line of light, now available in multiple configurations ideal for a variety of lens-free “veiled source ambient” architectural applications.

Stream Series Square: An uninterrupted line of light that extends as far as the blueprint dictates with veiled LED source and patented WhiteOptics 99% efficient reflector that provides even illumination.

Award-winning Indirect Ceiling Wash: Extreme low angle batwing shape creates uniform ceilings and minimizes glare on glossy devices.

Stream Series Oval:
Elegant, nature-inspired curves reminiscent of a leaf about to unfurl.

Stream Series Perimeter: Asymmetric distribution and a cove-like feel with high efficacies and no seams.

Stream Series Recessed 2˝ and 4˝: The first veiled source ambient luminaire now available with 2.5˝ aperture. Less is more with a new 2˝ version of the original “indirect” recessed linear Stream 4˝, recognized for distributing light more evenly than typical lens recessed fixtures, allowing for wider spacing, fewer fixtures and more energy savings.

Stream Recessed 4”: Its wide-distribution design means more spacing between fixtures, requiring fewer luminaries, significantly exceeding industry standards.

The Female Form Dressed in Light

(may not be suitable for all audiences)

femaleParisian photographer Dani Olivier wanted to do nude portraits that haven’t been done before. He had an idea: use the body as canvas for light projections.

The results are quite beautiful. Check it out here.

Tom Butters Named IES Director of Education

iesThe Illuminating Engineering Society (IES) has appointed Tom Butters as the new IES Director of Education, effective August 1, 2016.

This new position was established to address the growing need for continuing education courses in the lighting industry and the expanding role of education within IES for the benefit of its members. Butters will oversee the development, implementation and delivery of IES educational programs for professional development, higher educational institutions, and the public at-large. In addition, Butters will develop educational outreach tools and activities to assist lighting professionals in advancing their proficiency through continuing education. Butters will report to the Executive Vice President and work closely with the Directors of Standards and Membership Services.

Since 2007, Butters has been Director/Sr. Manager of Canlyte’s Lighting Concept Centre/Philips Lighting University, one of the busiest educational facilities in North America. He has 30 years in the lighting industry with 15 years developing and delivering lighting education programs based on IES recommendations to all segments of the industry. Butters has served as a Board Director, President, and Education Chair of the Toronto Section of the IES. He was also Vice District Chair of the IES District for Eastern Canada.

Product Monday: Cree Expands OSQ with Higher Output Luminaire

Cree has extended its OSQ Series Area and Flood LED luminaires with a new OSQ 28L Outdoor Area and Flood LED luminaire. This high-output option delivers up to 28,285 lumens, which enables the replacement of HID luminaires up to 1000W.

The OSQ Series blends optical control, advanced thermal management and clean aesthetics to reduce maintenance and energy costs. The housing is rugged cast aluminum with an integral weather-tight LED driver compartment. Versatile mounting configurations offer simple installation, and its low-profile design minimizes wind load requirements and blends into the site.

Available in 3000K, 4000K and 5700K color temperatures with a 100,000-hour rated life, the OSQ Area and Flood LED luminaires are backed by Cree’s 10-year warranty.

New Technology Converts Windows into Transparent Solar Panels

Based on a belief solar cells should be integrated with everyday products and surfaces, Ubiquitous Energy has developed the first transparent solar cell. The film can be applied to any surface to generate power. Imagine phones and tablets that can be recharged from light and skyscrapers that can use windows as solar energy sources.

Scientists Discover New Form of Light

Irish researchers have discovered a new form of light.

Light travels in a straight line but also rotates around its axis. It was believed the angular momentum of these photos was a multiple of Planck’s constant, which sets the scale for quantum effects. The researchers theorized certain quantum effects slowed the angular momentum of these photons. They passed light through a crystal and confirmed the theory, measuring angular momentum of half of Planck’s constant. The result is a new form of light, which may have profound effects on optical communications.

IESNYC Announces Winners of the 2016 Student Lighting Competition

Now in its 16th year, the Illuminating Engineering Society New York City Section’s (IESNYC) Student Lighting Competition (SLC) awarded “12:04:24 – 12:04:50 AM,” a collaboration between Leela Shanker and Samuel Powers, the Grand Prize.

Both students are enrolled in a dual-degree program combining the Master of Fine Arts in Lighting Design and a Master of Architecture in the School of Constructed Environments at Parsons The New School of Design. The team receives a cash award of $2,000.

Pratt Institute’s Zhijian Xiong’s “Tail Away” and Diana Tsoy’s “Space, In Time” won Second and Third Prize, respectively, and will receive cash awards of $1,000 and $500. They as well as the six students recognized as Honorable Mentions are attending Pratt Institute and are pursuing a Bachelors of Industrial Design.
