How many energy-efficient or certified buildings are not living up to the label? Very, very many, if this Ohio commissioning/auditing firm’s experience is close to typical. They report on common weaknesses in efficiency strategies and on real-life patterns of upgrades gone wrong across an array of equipment types. While flaws in well-intentioned processes remain, a more careful investment of human energy can still yield the desired reduction in building energy.
Here, we depart from our occasional focus on controlling smoke, yielding the floor to a life safety veteran weighing in about a new development for detecting it. Some historical context around detector types and testing methods paves the way for an explanation of why the new approach may become a welcome option for many applications … if it catches on.
A small team led by an award-winning Florida engineer decided to test conventional wisdom about pressure loss, both in a straight run and in comparing supply and exhaust scenarios. Early returns suggest the data may be flowing in an unexpected fashion.
Achieving deep energy savings is especially challenging when you’re faced with an existing structure with poor orientation, historic preservation requirements, and little space for renewables. The Byron Rogers Federal Office Building’s retrofit is scheduled to be completed in 2013; the post-renovation building is projected to consume less than half the energy it did before.
When you check into a hotel, you fully expect to be able to control the temperature of your room. The downfall to providing customer comfort is that it can raise energy costs if a room cools down or heats up when nobody is in it.

Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop. Learn more about Grounded In Reality in the December issue. Other topics in the December issue include health care HVAC, Boilders, check out the Back2Basics, and more.
