Is An LED Right For Your Next Retrofit Project?

Consulting-Specifying Engineer, Aug. 2016, by Tom Divine.

"As LED illumination technology improves in efficiency, reliability, and quality, building owners become interested in cost-effective ways to apply LED lighting in their facilities. In many cases, retrofitting existing fluorescent or incandescent luminaires will be an attractive alternative to wholesale fixture replacement. This article explores the effects of some of the applicable codes on LED retrofit projects."

Net Positive Energy Buildings

ASHRAE Journal, Aug. 2016, by Dylan Connelly and Laura Fedoruk. (Article Summary only.)

"DPR Construction’s retrofitted San Francisco headquarters building achieved approximately 20% net positive energy its first year of operation using efficient systems including HVAC, electrical and PV. And, in late 2015, it was certified as a net zero energy building. The office building demonstrates the capabilities of integrated, innovative, and replicable design. And, it proves that sustainable buildings can reduce energy use and improve indoor environmental conditions, while being cost effective. It has become a hub for learning and collaborating on many sustainably minded design projects."

Squeeze Efficiency from Window Upgrades

Buildings, Aug. 2016, by Robert Nieminen.

"Window replacement isn’t cheap, but neither are existing windows that are out of date and inefficient. The opportunity to upgrade comes around infrequently – possibly as part of a broader energy conservation plan funded by one financial package – so owners must maximize their return."

Replacing a Steam Boiler

Engineered Systems, Jun 2016, by Ray Wohlfarth.

"When designing or replacing a low pressure steam boiler, throw out everything you know about hydronic boilers. A steam system is closer in operation to an air conditioning unit than it is to a hydronic boiler. If you design a steam system using hydronic design methods, it will not operate properly. A hydronic system uses sensible heat while a steam system uses both sensible and latent heat. Sensible heat can be measured with a thermometer while latent heat causes a change of state and cannot be measured accurately with a thermometer. The following are some of the steps I take when designing a replacement steam system."

Retrofitting Steam Boilers For Large Health Care Projects

Engineered Systems, Mar. 2016, by Gary Hamilton.

"Replacing boilers for health care facilities provide many benefits to central utility plant operation; the newer boilers are more energy efficient, more sustainable, and more fuel-efficient than older boilers."

Replacing The "Engine" On Your Boiler System

Engineered Systems, Sep. 2015, by Ray Wohlfarth.

"Pumps, flues, valves, sizing, maintenance... there's a lot more to consider than just the boiler. Keep the car metaphor in mind, and your next replacement might not drive you to despair."

Energy Efficiency: Data Should Drive Energy Upgrades

Building Operating Management, July 2015, by Richard Lubinski.

"It’s important for facility managers to understand the importance of data before, during, and after energy efficiency projects. Data can be your friend. Data — which as we’ll see, comes from such sources as utility bills, meters, submeters, and data loggers — guides energy audits (also called energy assessments) that lead to the creation of energy conservation measures (ECMs) that in turn will serve the building’s interests. Those audits also provide reliable estimates of energy savings and return on investment (ROI) — an important benefit, since measurement and verification (M&V) are essential with energy upgrades."
