1. Tips for Earning Energy Efficiency Rebates
This is Casey Laughman, managing editor of Building Operating Management magazine. Today's tip is that energy efficiency rebates are available if you know where to look.
The past few years have been good ones for facility managers who want to use utility incentives to smooth the path to energy upgrades. In 2010, rate-payer funded programs provided $5.5 billion in incentives, according to the American Council for an Energy Efficient Economy. The usual incentive of choice is the rebate. On individual projects, rebates may cover 15 to 20 percent of capital costs.
It can be a major disappointment for facility managers who fail to qualify for rebates they were hoping to get. But in many cases, facility managers have only themselves to blame. There are plenty of reasons that facility managers lose out on rebates, and many have to do with mistakes made in the application process.
To make the most of rebates, facility managers must, first and foremost, pay attention. Specifically, they need to pay attention to when rebates become available, when the paperwork needs to be in and how to dot all their i's and cross all their t's.
Demand-side management programs — a category that includes rebates as well as other utility incentives — have become so popular that utility companies sometimes run out of funds early in the year. That's why it's important to get applications in early. Facility managers can sometimes plan ahead, so that upgrades or new equipment installation coincide with available money from utility companies. For example, some utilities have been offering incentives to replace T12 lamps. This summer, new federal regulations will end the sale or import of most T12 lamps. Once those regulations are in effect, incentives to replace T12 lamps will be obsolete.
2. Automated Demand Response a Better Way to Shave Peak Load
This is Casey Laughman, managing editor of Building Operating Management magazine. Today's tip is that automated demand response can help manage your power usage.
The California energy crisis of the late 1990s exposed broad weaknesses in existing utility demand-response capabilities.
Issues included lack of availability and reliable performance, utility control strategies that often conflicted with occupant comfort and business operating requirements, and incompatibilities with existing building energy management systems. Utility-provided control switches often had limited functionality, and event notification for commercial buildings often required building operators to be present, to acknowledge signals, and to manually manage response settings.
The Open Automated Demand Response information exchange specification, known as OpenADR, was developed to reduce the cost, expand the availability, and improve the effectiveness and value of DR. OpenADR redefines conventional DR to make it more scalable and flexible. OpenADR also transfers decision making and control from the utility to the customer and integrates DR with existing building energy management and control systems. OpenADR is on track to become a national standard, which will further reduce costs and expand support among energy service providers and building system and controls vendors.
With automated demand response, price and reliability signals are communicated directly to existing energy management and controls systems or end-use equipment controllers. Facility managers develop pre-determined DR strategies based on an energy audit or building commissioning. These are automatically activated in response to price and reliability events. This approach allows facility managers to design response strategies that are consistent with business operations, tenant comfort and lease requirements.
Linking event signals to existing energy management systems provides facility managers with control and flexibility to develop more sophisticated response strategies encompassing a range of loads. While Auto-DR enables facility managers to opt-out of any event, the machine-to-machine automated approach eliminates the need to curtail loads manually.
4. Assess Energy Options Carefully
This is Casey Laughman, managing editor of Building Operating Management magazine. Today's tip is to carefully consider your options before taking steps to cut energy costs.
When considering ways to cut energy costs, facility managers are confronted by myriad choices: energy efficiency upgrades, renewable energy alternatives and energy procurement options. All may yield financial savings, but which comes first — or last? Understanding how they may interact could increase the return on investment (ROI) while avoiding some costly disappointments.
Talk to a contractor, and you may be told to first change out all your T12 fluorescent lighting, or install variable speed drives on HVAC fans, or perhaps replace your boiler. On the other hand, a renewables vendor may tell you to start by adding photovoltaic panels on your roof, or installing a geothermal heat pump, before a hefty state or utility rebate program gets maxed out by others doing so.
An energy broker may claim you can save more by buying your fuel or electricity through him than you'll ever save from upgrading equipment, so that's where you should start.
But the best place to begin is with a thorough energy analysis covering all those bases. Such an analysis, when conducted by an independent professional energy consultant, generally prioritizes options (or combinations thereof) based on how quickly they return the investment as savings (i.e., ROI). Doing so may provide guidance that alters both the choices and the order in which they should be pursued.
In the past, analyses of energy cost, use, and options were called "energy audits." That term fell out of favor because it sounded too much like an investigation into one's finances. Today's term is "assessment." Along with a study of energy efficiency choices, the best assessments include an examination of appropriate renewable energy options and energy procurement strategies.
