I wrote many articles for LD&A and Energy User News Magazines through 2004, and those articles were available for free on this website. Since those articles are now considered out of date, they are no longer available. Following are three articles, which have withstood the test of time, especially with some minor updates. Also available for free is a lighting glossary.

Best Practice Report and Dimming Ballasts – Buyer Beware have been substantially revised this year.

Best Practice Report     Request Form

This 17 page report focuses on state of the art strategies and products in order to provide very low power densities, such as .4 – .6 watts per square foot in typical offices including ambient and task lights, while providing very good light quality, without the need of expensive and complex dimming systems.

This report, which applies to retrofits, remodels, new construction and maintenance, is a road map to an optimal balance of:

• Cutting edge energy efficiency
• Architectural appearance
• Lighting quality
• Control flexibility
• Ease of use
• Initial cost
• Utility or 3^rd party incentives
• Parts maintenance costs
• Labor maintenance cost
• Sustainability

Dimming Ballasts – Buyer Beware     Request Form

This is a 6 page report. Fluorescent dimming ballasts and associated control systems are often promoted as the Holy Grail for daylight harvesting and peak load shedding. Unfortunately, I have been involved with dimming system projects in offices, schools and warehouses, and feel sorry that the end customers are burdened by those systems. Here are 10 points to remember when you consider a dimming-based system:

1          Follow The Money

2          Just Because A Ballast Dims, Does not Mean It Will Save you Money

3          Raise The Bar And Demand Best Practices Before You Dim

4          Ask Facility People Who Have Dimming Systems If They Like Them

5          Commissioning Costs Must Be Documented And Added To Life Cycle Costs

6          Sustainability Has To Survive Real-World Changes To Work

7          Worker Satisfaction Reflects Good Lighting, Not Just Dimming

8          Compare Daylight Switching With Daylight Dimming Before You Buy

9          There IS Some Help Available

10        The Future May Be Better

2          System Efficacy At Optimal Temperatures

3          Lamp Temperature & Light Output

4          Ballast Issues
