Today, many state institutions of higher learning and healthcare facilities face reduced budgets, aging infrastructure, and rising energy costs. According to the EPA, colleges and universities spend close to $2 billion each year on energy. These institutions are seeking innovative ways to renew facilities, improve energy efficiency, and reduce energy costs. One option gaining some renewed momentum is the Energy Savings Performance Contract (EPSC).

Tool lending library assists California companies in measuring energy consump-tion

No Comments
Most companies want to decrease their energy consumption, either for financial reasons, or to be active in reducing their carbon footprint, or both — but some of them aren’t sure where to begin. When the only measure of a facility’s energy usage is the bill customers receive at the end of the month, they may feel their facility is more like the proverbial black hole: power goes in, business happens inside, but it’s not clear exactly how much energy is used where and when.

How The Culture Of Inefficiency Is Outfoxing LEED®, ASHRAE, And Efficiency Programs

By Peter Kleinhenz, MS, P.E., Greg Raffio, MS, P.E., Charlie Schreier, MS, P.E., John Seryak, and Franc Sever, MS
3 Comments
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.

Right Steps For Retrofits

By Kendra Tupper, P.E., LEED® BD+C, ASHRAE BEMP & HPDP
No Comments
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.
