Outsmarting Your Building
A couple posts ago I raised a point about buildings being smarter than the owners. So what is the solution? How can an owner or manager get control of their building and get the operations and maintenance running in an optimal budget?
Free: Advanced Energy Design Guides
ASHRAE and its partnering organizations have made the Advanced Energy Design Guides available as free PDFs. The guides encourage energy efficient design in a range of building types: K-12 schools, small office and retail buildings, small warehouses and self-storage buildings and highway lodging.
They are available at www.ashrae.org/freeaedg.
The guides help to educate the marketplace on how to build energy efficient buildings that use significantly less energy than those built to the minimum code requirements.
Joseph Lstiburek
I’ve notice many of my favorite articles in the ASHRAE Journal are written by Mr Lstiburek Ph.D., P.Eng. I like his sarcastic writing style. I find it fun to read. His topics revolve around proper building construction and how it relates to HVAC. This makes sense as he’s a principle of the Building Science Corporation.
Some might think he’s a curmudgeon but it sounds like common sense to me. The ASHRAE Journal gets pretty dry at times so Joe gets my thanks. One of his many articles is “Some Old Lessons Distilled” about Bourbon Distillers in Kentucky. He tours an old distillery and shows how new distilleries are recreating the temperature swings and humidity control using newer and cheaper building materials.
This is one of the few articles that seems to be available for free on the ashrae.org website. You can also buy a reprint of this September 2008 article.
Light Levels
Measuring Light Levels, Selecting the Right Ballast & Lamp Combination, and Graphing the Results.
Before this grocery store was retrofitted with energy efficient T8 lamps and Electronic Ballasts, we went in and took light level readings. (In Lumens)
Then we graphed the results using an overlay of the store walls, aisles and check out tellers.
By doing this we were able to match the correct ballast and lamp combination to the fixture.
In areas were there was inadequate light we used a high output combination.
Where there was adequate light we used standard combinations.
Where there was more light than required we de-lamped the fixture.

When A Date Goes Bad
This post isn’t about dating. I’m the last one to give advice on that topic. Instead this about what to do if you have a bunch of digital photos with the wrong date. This can be caused by forgetting to reset the clock when changing the batteries, or vacationing in a different time zone, or even scanning film photos.
