Exterior Lighting: Onwards and Upwards
Approaching a lighting design project is always a balancing act of multiple goals towards a single end: a beautifully lighted project that enhances the perception of the place, meets the budget, and satisfies code requirements. But as discussions of dark-sky compliance and reduced power consumption to meet stringent new requirements have come to the... »
Basic Sustainable Lighting Concepts: On Lighting Controls
Part 4 of an ongoing series outlining design principles for sustainable lighting design: here are a few ideas regarding daylighting, to help navigate the greenwash. Controls: use them! It’s really not acceptable to use simple switches and whole-floor relays anymore. Some energy codes may still allow it, but that doesn’t mean it’s good practice.... »
The Lure of the Time-Based Energy Code
Energy codes got you down? Is squeezing wattage cramping your design? You’re not alone – a lot of designers feel this way, and for good reason. As the country demands more and more energy efficiency, we’re spending more and more time counting watts and squeezing every last drop from power allowances just to make... »
Season’s Energy Code Greetings
With the onset of the holiday season, we have also come to the end of the three-year energy code development season. The new 2010 version of ASHRAE/IES Standard 90.1 has been published, and IECC-2012 will be published in April 2011. (No, that’s not a typo. IECC-2012 will be published in 2011. Don’t ask, I... »
New Energy Codes, New Challenges
Readers of this blog have already heard about the new Green Building codes, but there are new versions in the works, both of the energy code standard ASHRAE/IES 90.1, and of the International Conservation Code (IECC). What will these codes look like, and how will they affect the work of architectural lighting designers? The... »
Dawn of the Daylighting Codes
It’s pretty safe to say that people like daylight and sunlight. Daylight is good for people, since it sets our biological rhythms, gives us a connection to the weather and time, keeps us physically and mentally healthy, and obviously allows us to perform visual tasks. It’s no wonder then, that architects through the ages... »
Fight the Power!
Compliance with energy codes has become a regular part of the design process for lighting designers in recent years. Prior to the release of the 2004 version of the ASHRAE/IES 90.1 standard for energy codes, it was easy to design lighting without worrying about bumping into code limits. This was because codes had not... »
Making the Sausage
You’ve heard the saying, “There are two things you will never wish to watch: the making of sausage and the making of legislation.” As the new chair of the Energy and Sustainability Committee of the International Association of Lighting Designers (IALD), I’ve been getting a glimpse into the kitchen. Why, you might ask, would... »
