The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) recently published guides on how to design buildings that achieve net-zero energy consumption without compromising quality.
Building upon previous guides targeting deep energy savings, the first two new guides were developed in partnership with the American Institute of Architects, Illuminating Engineering Society, and U.S. Green Building Council, and target K-12 and small to medium office buildings.
Here Comes BACnet Secure Connect
By early 2020, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) is expected to release a new version of the BACnet building automation system protocol. BACnet Secure Connect, or BACnet/SC, brings this popular open industry standard into the Internet of Things (IoT) age by enabling the easy and secure transfer of large volumes of data.
University of Oregon Evaluates Impact of Daylight, Views, and Controllable Lighting
In August 2019, the University of Oregon published a whitepaper, “The Impact of Lighting and Views in the Workplace of the Future.” The paper concludes that daylighted spaces with controlled lighting and views can improve occupant well-being, workplace productivity, and satisfaction by positively influencing various physiological and psychological processes. Lighting and views also impact property value and employee recruitment and retention, the researchers said.
DOE Evaluates Tunable-White Classroom Lighting
Tunable-white LED lighting offers highly efficient general illumination combined with dimming and the ability to tune correlated color temperature (CCT) from warm- to cool-white. A strong potential application is classrooms, where teachers can set lighting/visual conditions to support classroom activities. In May 2019, the Department of Energy (DOE) published a Pacific Northwest National Laboratory (PNNL) report evaluating a trial installation of tunable-white lighting systems at three classrooms in an elementary school in Folsom, California.
DELTA Study Evaluates Residential Sensors
The Lighting Research Center (LRC) recently published a new DELTA report evaluating new sensor-controlled LED corridor lighting installed in a multifamily residential building in Albany, New York. The project showed significant energy savings while overall occupant response was positive.
Quick Guide to The Latest Commercial Building Energy Code Standards
This article provides general introductory knowledge about the lighting control requirements imposed by the 2016 version of ASHRAE/IES 90.1 and the 2018 version of the IECC.
Lighting as a Service
Lighting as a Service (LaaS) is an emerging and evolving business model in which the owner pays for light rather than the equipment that delivers it. The owner buys new lighting on a subscription basis over a multi-year term rather than a significant one-time capital investment.
Lighting Control for Lighting Quality
Networked lighting controls can reduce energy consumption by an average 47 percent, according to a recent industry study. That makes control a powerful tool in managing energy costs, but it only captures a small fraction of its potential value in enhancing quality lighting with LED technology.
2019 Nonresidential Construction Forecast: Cautious Positivity
The AIA’s semi-annual Consensus Construction Forecast, a survey of the nation’s leading construction forecasters, is projecting 4.4% growth in nonresidential construction spending in 2019 and 2.4% in 2020. This article by Craig DiLouie, LC, CLCP reviews the forecast and leading construction industry economic indicators.
Eight Tips for Lighting Cybersecurity
Cybersecurity is a challenge for the Internet of Things (IoT) as a whole (and corporate information networks beyond that), and lighting is not immune. This article discusses the issues involved and what specifiers and designers can do to mitigate any risks.
