Daylighting

A new approach to windows that could let in more light and cut indoor lighting needs by up to 99% in buildings in Tropical regions without losing the cooling effect of shades. Details are reported in the International Journal of Engineering Systems Modelling and Simulation this month. Lerdlekha Tanachaikhan and colleagues in the School of [...]

The Energy Center of Wisconsin will host a seminar by lighting designer Jim Benya on how to achieve energy-efficient lighting and daylighting designs that maximize both lighting quality and energy efficiency. In this seminar, Benya will examine the latest technologies and strategies to achieve superior lighting design essential for energy efficient and high performance buildings. [...]

In this presentation, Jean-Louis Scartezzini and Mirjam Münch, from the Solar Energy and Building Physics Laboratory at EPFL, present their experiences with daylighting research and technology. Their work illustrates possible integration steps toward optimized “Day and Night” lighting environments with respect to energy consumption and human health. Marilyne Andersen, associate professor in the Building Technology [...]

While not an electric light source, daylight is an important layer to consider in a lighting design in any space that has daylight apertures such as windows and skylights. In its simplest definition, daylighting is the use of daylight as the primary source of illumination in a space. Daylighting is also related to providing access [...]

ArchitectCES.com, the American Institute of Architects (AIA) Continuing Education Services (AIA/CES) provider, has added “Introduction to Tubular Daylighting Devices,” delivered by manufacturer Solatube, valued at 1 LU/HSW/SD hour. Students will learn: why daylight is so important and identify the reasons for using daylighting in commercial environments to identify the available daylighting strategies and identify their [...]

The University of California, Davis has signed co-exclusive license agreements with Wattstopper and Axis Technologies Inc. to commercialize inventions that reduce the cost and increase the reliability of daylight harvesting systems–control systems that automatically adjust indoor lighting to match changes in ambient daylight. The license agreements cover a package of strategies and technologies developed by [...]

As I wrote in a previous post here, I’m supporting the IES Commissioning Committee in developing an RP about lighting and control commissioning, including commissioning of lighting and, separately, commissioning of lighting controls. We are considering including some guidance on commissioning daylighting—both its interaction with the electric lighting system, and as an independent light source [...]

Researchers at the National Renewable Energy Laboratory are working on the technological equivalent of putting sunglasses on buildings with a new generation of insulated “dynamic windows” that change color to modulate interior temperatures and lighting. NEMA’s got the story here.
