Don’t Go to Home Depot For Energy Retrofits

Today, building owners embarking on an energy upgrade to save costs have more data and more options than ever. More efficient HVAC systems, lights, windows, motors, and other equipment gives you many ways to save. In addition, technology from the many types of sensors and software can provide you with accurate site-specific energy data.

How do you start?

Start with an energy audit performed by an experienced engineer. The auditor should have not only an appropriate certification, such as Certified Energy Manager or Certified Energy Auditor, but should also have experience. The auditor should be provided historic energy use data and specifications and other information about your building and its energy systems. A good energy audit will contain estimations of how much energy is used for heating, cooling, hot water, lighting, plug loads, etc. Armed with this information, the auditor can likely suggest several potential strategies to reduce energy usage throughout the building, what the upfront costs would be, cost savings, and ROI and simple payback. You the building owner can then make an informed decision on which projects to do and which not to do, and how to prioritize.

Implementation of selected energy-saving projects is not simple. It is tempting for a building owner to take short cuts to raise the ROI. For example, for an energy audit suggesting LED light substitution, the manager may go to “Home Depot” or similar retailer and just buy LED bulbs that appear to fit in “the socket”. This is a big mistake. The LED market is still variable, with a number of new vendors selling bulbs that do not meet standards. Good LED lights can last for tens of thousands of hours of operation. But some vendors sell inferior ones that can break down much sooner. Many retailers do not so differentiate and just want to sell the cheapest bulbs they can.

The better alternative

Stick with the energy professional to implement the energy strategies you choose. Besides ensuring a better, more reliable product, the professional often knows which incentive programs apply and can test and ensure your upgrades actually are working properly – to maximize your full benefits.

I recently performed an energy audit for a small office building, which included information about installing LEDs and occupancy sensors. The building’s owner, a DIY advocate, went to Home Depot and bought and installed the LEDs and sensors. I warned him, but he did it and now has lighting concerns and sensors that turn off lights in rooms while people are inside. He saved money, but has inconvenienced and potentially put workers and customers at some safety risk – to save some extra $.

Financing may be an issue. Your energy professional will likely know financial firms that offer low-interest financing. Financial firms are aware of the great ROI of energy upgrades and will “fight” for your business, as the default risk is low. You can implement selected energy projects with no money down. Your energy professional can help.

So, building owners and managers, here are some additional ways the time and expertise of an experienced energy professional is of great value for you.

• Comprehensive knowledge of technologies. Experienced energy experts work or read up on the latest technologies daily. We have a better knowledge of what will and won’t work in different situations compared to others, who might, at best, pay attention to energy issues sporadically. It is important to consider issues of billing, use and orientation the building, equipment age, etc. not one technology fits all situations. And going to the retail store to buy energy-efficient equipment misses your specific needs. Our expertise is worth the extra money spent in terms of additional savings, not to mention reliability and productivity.

• Planning. The energy professional can help a building owner make an informed decision on how to prioritize energy projects. With the recent revolution of energy technology, it is likely that several strategies will benefit you. The energy pro can lay out your options, recommend which ones make sense to go in a certain order to get more “bang for the buck”, and be able to reinvest savings from one project to the next. The energy pro can tell you which strategies are additive and which are exclusive. Perhaps, for example, money is so tight you can only upgrade a limited number of windows with film. The smart energy professional would tell you to prioritize the north-facing windows as they lose the most conditioned (heated) air in the winter. Without this advice, the building owner/manager may pick a hodgepodge of windows to treat, reducing the cost savings.

• Implementing your strategies. OK, you have developed a plan to implement one or several energy saving strategies. Bringing in the right technology vendor is important, but as important is the right subs to install it properly. It needs to be done right. Developing a bidding process takes time. The energy professional has done this before, knows how to put an RFP together, and understands the proposals to make a fair “apples-to-apples” comparison. Or the building manager can trust the experience of the energy professional to bring in a reliable vendor to do the job right. Either way, this is a big time saver for building staff.

• The implementation process. A factor that building owners/managers often overlook is the impact of the installation on their buildings and tenants. Do not just schedule a date for installation without an understanding of the process and infrastructure (doors, elevators, etc.) needed and effects (noise, space). One does not want to ruffle feathers of a tenant who may have a critical meeting that day and cannot afford to have construction noise. I worked with a client involved in a major capital project at his building across the street from the school. It was felt it was better to conduct the actual installation during the weekend to not effect or risk the school. Also, it is important for the installer not to be “surprised” so the installation goes smoothly and is not unnecessarily delayed. The energy professional can work with the installer to determine a plan which, together with management and tenants, causes the least amount of upheaval for all involved.

• How did it go? It is tempting to buy and install the energy technology, pat oneself on the back, and move on. We always look forward. But it is important to know how the strategy is performing. Is it really giving you the cost savings and payback predicted? Is the technology operating properly, as promised? The energy professional can monitor or commission its operation and provide a more nuanced approach to not only your direct energy cost savings, but also added benefits, such as productivity, work by O&M staff, etc. This provides robust data needed by management to know to determine the success of energy strategies.

So while it is tempting to take the results of an energy audit or even information from an article and just “go to Home Depot”, pick up equipment and DIY, it is really in your best interest in terms of building function and cost savings to have an experienced energy professional manage the implementation of energy-saving strategies that you choose.

Case Study: CCES Performs Energy Evaluation to Settle Landlord-Tenant Dispute

Climate Change & Environmental Services (CCES) performed an energy evaluation used to settle a landlord-tenant dispute. The landlord operates a mall in New York City with a main meter for electricity serving one restaurant plus a number of offices and common area in the complex. The landlord had been charging tenants for electricity based on a percentage of the meter reading, based on relative square footage. However, the landlord realized that the restaurant, with extended hours, large refrigeration needs, and an electric oven and domestic hot water, used much more electricity than the offices and common area. As a result, they doubled the proportion assessed to the restaurant, which the restaurant owner disputed.

CCES performed a comprehensive energy estimate of one year’s worth of energy usage of the restaurant, offices, and common areas all served by the main meter, based on sources of electricity and their average usage and time of operation. CCES determined that based on actual equipment and operations the usage of electricity by the restaurant was actually greater than that in the re-assessment made by the landlord. The report was reviewed for technical accuracy and was approved, and helped settle the landlord-tenant dispute.

Highlights of the Clean Power Plan of 2015

You have probably heard about the release of the final version of the Clean Power Plan on Aug. 3, 2015 ( Clean Power Plan Fact Sheet: ( It sets even stricter emission standards than the initial proposal of last year. The Clean Power Plan aims to cut GHG emissions by 32% from a 2005 baseline by 2030, while giving states greater flexibility to meet standards, such as that reductions do not need to begin to be achieved until 2020. Emission reductions must be phased in on a “gradual glide path” to 2030.


Under the Clean Power Plan, states must develop and submit a plan by 2018 to the USEPA for their approval containing the strategies to ensure that their power plants individually or as a group meet specific GHG performance rates for 2030 and for the years between 2022 and 2029. States will have until 2022 to begin phasing in emission reductions. This is a two year extension from the dates contained in the proposed rule.

States may choose between two approaches to meet their goals:
1. Emission standards plan – with power plant-specific emission rate or fuel-based requirements that a state must enforce that will achieve the required reductions.
2. State measures plan– includes a mixture of measures enforced by the state, such as power plant-specific emission reduction standards, renewable energy standards, and programs to improve energy efficiency not included in the “best systems” list. The federally-enforceable requirements (on the “best systems” list) and any state-only measures must result in all power plants meeting the state’s GHG emission reduction goal.

Specific Program Elements

The Plan contains a Clean Energy Incentive Program to further incentivize renewable energy, offering credits for renewable energy installed in 2020 and 2021. These credits can then be used for the compliance period starting in 2022.

The Clean Power Plan contains a “safety valve” allowing states relief of their emission reduction standard if there is risk of disruption of its power supply. A state may drive certain high-emitting power plants to retire quickly to meet a 2020’s reduction goal before a new source necessary to take its place in producing electricity is up and running. There are also allowances for states to request extensions to deadlines.

Finally, the Clean Power Plan allows for interstate trading of GHG emission reduction credits, giving another option to states – to procure credits from states which have achieved over-reduction of GHG emissions, beyond their goals. The Plan provides guidance for states who wish to establish such a trading program. The USEPA wishes to encourage such trading programs, such as the successful RGGI program in the Northeast.

Early Reaction

The early response has been mixed. Republicans will try to block its implementation, as it will certainly impact the power and coal industries. The National Association of Manufacturers is against the rule. The Plan will likely be challenged in court. However, 365 major companies and investors including General Mills, Mars, Nestle, and Unilever sent supporting letters for the Plan.

The Advanced Energy Economy (AEE) was upset that the Plan contains no credit for actions taken between now and 2020, and that energy efficiency was removed from “the best system of emission reduction” methods used to set state-by-state targets. The 3 main “best systems” listed are improved heat rate at coal-fired facilities, increased use of natural gas, and use of renewable (carbon-free) energy. It is understood, however, that energy efficiency programs can still be included in state compliance plans. It is likely that energy efficiency was removed as a “best system” because it represents efforts outside the property lines of power plants, which is harder to measure and may have legal obstacles for affected power plants.

CCES can help your building or company focus on your energy needs. We have successfully found reliable ways to save energy usage and cost of many building types. And we can translate such reductions into GHG emission reductions, too. We can develop and reduce your carbon footprint to obtain maximum financial benefits, too.

Basics of Sub-metering: Why It’s Good For You

Benefits of Sub-metering

Given the expense decades ago of purchasing multiple electric meters and the needed wiring, many multi-tenant buildings (both residential and commercial) have a single master or small number of meters to record electric usage. This leads to many issues, such as fairly assigning electric usage to specific tenant or operation and lack of motivation to conserve energy usage. If a building hosts a variety of tenant operations, it is likely one business or resident will pay more relative to what it is using (say, an office of any type compared to a restaurant). If you are paying a set percentage of the reading of the master meter, what motivation do is there to reduce usage?

Given the benefits and reduction in costs to do so, sub-metering is becoming an option many are considering. At least two cities, New York and Philadelphia, have promulgated laws to mandate sub-metering in certain situations. A recent report in EE Reports ( provides robust guides to the basics of sub-metering.

Perhaps the biggest argument for sub-metering is the eventual cost savings. If each tenant of a building has its own electric meter and learns what they actually use and have to pay for it, behavior (when it comes to energy usage) will change fairly quickly. The DOE has published the range of 5-15% savings in energy usage as tenants absorb the meaning of their high bills, realize they can now control their usage, and begin to implement simple strategies to reduce usage (more efficient equipment, not leaving on equipment, etc.). And these strategies have a short payback, generally under 3 years. A recent study in a NYC high-rise residential building showed 20% overall energy savings.

Planning for Sub-metering

Like many things with energy, this is not a matter of going out and quickly buying and installing meters and expecting great savings. Planning is important. Ideally, the building owner should research different types of sub-meters with different types of data displays, such as graphical, by time (hour by hour), or basic digital. Hour by hour is particularly powerful as it may identify areas of electricity usage you were unaware of, such as why is usage so high at night? Or why is it so high during a certain period in the workday? What equipment or department or group may be responsible? In addition, with many paying special rates for high demand during peak periods, hour by hour data can help you plan and verify that electricity-using operations are moved to non-peak periods, saving you tremendous costs on high peak demand charges.

Also, make sure that sub-meters that you procure be able to be checked and calibrated; that they are part of your measurement and verification (“M&V”) operations to ensure they are operating properly over time.

How To Think About Energy Efficiency

Last week, I gave a talk to an engineering society about sustainability, with the emphasis on energy conservation and greenhouse gas emission reductions. I discussed “The 9 Purely Business Reasons to Reduce Energy” (published earlier in this blog) to demonstrate the many purely common sense, financial reasons to invest in energy efficiency. Give credit to us engineers. A few people in the audience questioned the viability of these reasons and gave me a hard time. Although I emphasized the business value of reducing energy usage, these people were quick to point out that improving energy efficiency was no guarantee of cost savings; a strategy may be so expensive or not feasible such that it will not pay back the initial investment. This is true, and that’s why one needs to look individually at every building and situation and devise a host of potential strategies. Some will have a better ROI than others. And that’s a good reminder that “just going to Home Depot” to pick up some LEDs, does not guarantee savings (or proper lighting). We experienced engineers are needed.

My favorite example is a small business called Colonial Needle, a light industrial / warehouse / office 2-building complex in White Plains, NY. The buildings were built in the 1950’s and underwent essentially no changes since then, including having their original windows and boiler. Not only were their energy costs sky high, their workers were still uncomfortable; some were wearing parkas at their desks in the winter! Colonial Needle finally realized they had to upgrade and did so comprehensively. For example, they knew that there were cracks in many of the single-pane windows. While a window upgrade to double pane generally does not have a fast payback, it was critical for worker productivity and morale for wind not to blow onto people at their desks! Each building and situation is unique. It is important to bring in the right energy professional to lay out options and to look deeper into what the long-term costs and benefits are.

Another factor is to take advantage of incentives that exist for many energy efficiency projects. Governments – even in red states – are beginning to understand that incentives for private companies to implement energy efficiency projects is a productive way for a government to spend money. Some examples:

• Improved energy efficiency, by reducing a company’s expenses represents a boost for tax revenue and for creating new jobs, beneficial to any government.

• One or many buildings using less energy (more efficiently) also has health benefits. Less fuel combustion means reduced air pollution buildup and, therefore, reduced asthma and other respiratory diseases, meaning a happier and healthier population, using less government services.

• Using less energy in peak times reduces the stress on the energy delivery system. One apartment complex that switched from oil to natural gas (oil backup) noticed that the number of annual oil truck deliveries dropped from nearly 300 to two, through the narrow, complex streets of the neighborhood. Besides causing traffic jams, truck deliveries took workers away from other jobs, not to mention. So this change benefitted many.

• Reducing the amount of electricity used allows utilities to avoid or scale back the building of new or expanded power plants, transmission lines, and other necessary equipment and use existing infrastructure more effectively. This not only saves the utility much money and risk of potential failure, but also saves the consumers, too, as we all ultimately pay the bill.

This last point is a major reason why more and more utilities offer incentives to customers to use less energy. Yes, that sounds ironic – paying a bonus to customers to use less of the product they sell. But such incentives make sound sense given the alternative, multi-million or multi-billion dollar capital upgrade projects, which may or may not be fully funded and may or may not lead to unbridled success.

But back to you, our readers, who primarily work for companies and building owners and deal with a finite number of buildings and facilities. Why should your company invest in energy efficiency and how can you get others to push for this?

 The payback period for energy efficiency fell by over half when productivity and operational gains are estimated and brought into the calculations.

 Energy efficiency strategies can make buildings more comfortable, yielding healthier conditions for workers and residents. According to the International Energy Agency (IEA), for every $1 invested, energy efficiency provides up to $4 in benefits when the cost of medical care, lost work time and child care costs are considered.

 Energy efficiency strategies can attract new business, tourists, and investment dollars to the company or building. This is especially true in real estate, as energy efficiency can attract more potential renters (giving the owner the upper hand), the entertainment and health care industries, and for universities.

Companies, building owners and managers, governments, utilities, and yes, even engineers should stop thinking about energy efficiency as just another expense, and instead think of it as an investment to be studied and benefits maximized. No, not every energy efficiency project will pay back well. An experienced professional is needed to determine the most cost-effective projects. But so many opportunities in energy efficiency exist (growth in better systems/technology) to benefit nearly any company.

CCES has the experts to perform an energy audit to determine specific energy efficiency projects for your building or facility. We have the experience to quantify potential costs and long-term benefits, not only direct cost savings, but other business benefits, as well.

Case Study: CCES Performs Evaluation of Exterior Lighting for College

Climate Change & Environmental Services (CCES) performed an evaluation of the exterior lighting for a large college campus in New York City. While crime and other security issues were considered not a problem, the college understood that there were unlit spots in sections of its campus giving the perception of security issues, and that a number of lighting fixtures were broken.

CCES performed a comprehensive exterior lighting survey of the entire college campus, taking light meter readings during evenings approximately every 10 meters. Readings were recorded and compared to foot-candle standards used at other colleges to determine areas that are likely underlit given their use. In addition, fixtures with missing or broken lights were recorded.

Using Google Earth images throughout the campus, CCES developed maps of the campus showing the light meter readings and indicating areas that were underlit compared to recommended levels at college campuses. In fact, most of the exterior of the campus was determined to be underlit. Areas most walked through and most underlit were identified and highlighted to help the college prioritize their upgrade. Broken fixtures were also identified. Finally, the college committed to replacing broken lamps and upgrading and adding new fixtures to raise campus lighting levels with LED lamps wherever possible.

Follow Up on Supreme Court Ruling on Mercury Emissions

The U.S. Supreme Court ruled on June 29, 2015 that the USEPA acted unreasonably when it determined that it was appropriate and necessary to regulate mercury emissions from coal-fired power plants without including a cost analysis. The hazardous air pollutant section of the Clean Air Act (Section 112) states that the agency must first conclude that it is appropriate to regulate a hazardous compound, then propose, post, and promulgate the rule. The Court ruled that the agency failed to consider the cost of the regulation during that initial assessment of whether regulation of mercury was appropriate. The USEPA argued that it could not do an effective cost assessment early in the process until it determined at the required level of mercury emission reduction.

The Supreme Court’s decision does not invalidate the rule, but merely remands it back to the U.S. Court of Appeals, which can either vacate the rule or leave it in place while the USEPA provides further justification of its appropriateness. Absent in the Supreme Court ruling is any requirement on how it should consider costs in the future. The Court concluded that it is up to the Agency to decide how to account for cost.

As legal commentators have stated, if the mercury rule is vacated, it may have the ironic effect of helping the USEPA defend its forthcoming GHG rules for existing power plants, as one legal objection is that the USEPA lacks authority because it already regulates mercury emissions.

Another issue of concern in the Supreme Court ruling is the cost analysis performed by the USEPA when the rule’s parameters were finalized. The USEPA stated that the cost for compliance for would be several billion dollars per year, while the benefits would be in the millions per year range. But this was direct benefits due to decreased mercury emissions. If one considers additional secondary benefits (the same technology reduces other hazardous and non-hazardous air pollutants, such as fine PM, reducing other public health impacts, such as asthma), then the benefits are much greater, and exceed the cost. The Court noted, but did not rule on whether the Agency must look only at direct benefits for the pollutant(s) being regulated or can look at additional benefits, too.

It appears that in the near future, at least, the USEPA in performing its “appropriate and necessary” analysis before proposing a regulation for a hazardous air pollutant will need to determine probable emission limits necessary to at least minimally protect public health, and perform a cost-analysis on that basis.

According to legal commentators, this is among several decisions that appear to contradict each other (for example, a different court ruled that OSHA did not need to perform a cost-benefit analysis to promulgate its worker protection rules). So it is likely that this issue will be discussed in courts in the future.

Please note that this is not intended to be a legal analysis of the Supreme Court ruling. Please speak to a legal professional for an in-depth evaluation.

USEPA Eliminates Startup, Shutdown Malfunction Exemptions

On June 12, 2015, the USEPA published its final regulatory action requiring 36 states to remove from their State Implementation Plans (SIPs) exemptions from emission limits during startups, shutdowns and malfunctions (SSM). See:

This action requires 17 states to remove automatic exemption from emission limits in rules (affirmative defenses) because of SSM from their SIPs. This change will likely impact the operating procedures of many facilities that have automatic SSM exemptions included in their air permits and increase their compliance liability.

The USEPA first proposed this action in 2013 as a result of a Sierra Club petition. The USEPA revised its original proposal in 2014 after the D.C. Circuit Court held that an affirmative defense against civil penalties for toxic air emissions by Portland cement manufacturers, even in the event of an unavoidable malfunction, cannot be made.

In its discussion of this final action, the USEPA stated that while the agency was now prohibiting automatic SSM exemptions and affirmative defenses, it will allow discretion by air agency personnel exercised on a case-by-case basis. It encourages alternative emission limits or mandatory work practices to be required specifically for SSM events.

Affected states must submit their SIP revisions to the USEPA for approval by Nov. 22, 2016.

In the meantime, to properly prepare for implementation of this change affected facilities (those currently with SSM exemptions) should research and determine alternative emission limits that it can meet or work practices that it can implement during SSM events to provide to the applicable air agency when elimination of automatic SSM exemptions and affirmative defenses goes into effect, and the air permit must be re-examined and revised. It is likely that states will require such information during a future renewal or modification of an air permit. It is better for a facility to be “ahead of the game”, and provide proposed changes with rationale to the agency, who may have little basis to make a decision.

CCES has the experts to help you establish workable alternative emission limits and work practices during SSM events, and help you modify your permits – under your terms – and negotiate with your regulatory agency.

USEPA Announces Changes to Self-Audit Policy

While the USEPA spends a lot of time researching and writing rules that it has promulgated, another area of importance is enforcing these rules – to ensure they are fairly and evenly complied with. Besides the “stick” of fines, potential imprisonment, and bad publicity, the USEPA also uses the “carrot” of encouraging companies to comply by establishing a formal policy to waive the punitive portion of any penalties that would otherwise be assessed for violations if they are discovered independently by the facility, voluntarily disclosed to the USEPA, and promptly corrected. The USEPA’s “Incentives for Self-Policing: Discovery, Disclosure, Correction and Prevention of Violations” has been around since 2000 (modified in 2008) and been used successfully by companies since with compliance self-auditing programs, giving many a “clean slate.”

In 2012, during a time of budget cuts and reduced staff, the USEPA signaled that it may reduce involvement or even terminate the Audit Policy program.

However, on June 10, 2015, the USEPA held a webinar to confirm its strong support for the concept of self-auditing and announced changes to its Audit Policy and Small Business Compliance Policy to meet the same goals, while allowing the Agency to reduce effort spent. ( The USEPA has made the process electronic, creating an “eDisclosure Portal” to more efficiently collect information needed to determine whether a disclosure qualifies for the Audit Policy. It was designed to make the process close to self-executing. The trade-off for this efficiency increase is less flexibility to addressing unique individual circumstances.

For example, the Portal will track initial discovery, disclosure, compliance correction and certification dates, and automatically notify the submitter whether a deadline is missed (Audit Policy is non-applicable). The system is supposed to grant up to 30 additional days to complete compliance corrections above the normal 60 days. The applicant can request additional time to comply, but the USEPA will not rule on such a request until it reviews the entire request. Therefore, facilities taking added time to achieve compliance may find their extension request not granted and get no benefits under the Audit Policy.

Another potential problem with the new eDisclosure system for the user is that even if the system indicates that a facility meets all of the criteria to qualify for the Audit Policy program, such a final determination is only made by the USEPA after it reviews information inputted, and it has the right to contradict any statement from the system.

The USEPA does expect that the new eDisclosure system will ultimately benefit disclosing facilities, reducing their time and costs if they fully understand how to use the new system, collect and disclose all needed information fully, and meet all deadlines.

The eDisclosure system is expected to be launched in fall 2015. The new system may provide less certainty and less flexibility to applicants than current procedures, but will reduce time and costs to submit to the Agency necessary data, providing incentive to continue to use the Audit Policy to quickly disclose and correct violations and be rewarded for doing so.

CCES Case Study: NYC Local Law 87 Compliance for 2 Beverage Warehouses

Climate Change & Environmental Services (CCES) was the lead engineer for Manhattan Beer Distributors’ efforts to comply with New York City Local Law 87 (LL 87). Manhattan Beer Distributors operates two warehouse/office complexes in Bronx, NY.

CCES performed the energy audit and the retrocommissioning study for each 160,000+ sf facility to comply with NYC’s LL 87. An experienced CCES energy expert reviewed historic energy usage data, visited the facilities, and collected and analyzed technical data concerning its lighting, rooftop HVAC units, windows, and equipment operations. The data was used to develop an end-use estimate of electricity and natural gas usage by different equipment and operations. CCES developed a number of Energy Conservation Measures (ECMs) to reduce energy use and peak electricity demand, all with estimated costs, energy savings, and simple paybacks. Each strategy would result in a positive return on initial investment; potential financial incentives for the upfront costs through NYSERDA and Con Ed programs were considered in the calculations.

CCES also performed retro-commissioning of existing systems on-site at the two buildings, including inspecting HVAC, lighting, and building envelope. CCES determined a small number of deficiencies which Manhattan Beer Distributors quickly addressed to allow optimal operation of their systems.

Finally, CCES developed the appropriate reports required by LL 87, and submitted them to the NYC Dept of Buildings in a timely manner.

CCES has the certified professionals to perform and complete all parts of NYC Local Law 87 compliance requirements. Plus, we can help you use the information gained in the effort to help you reduce energy costs and gain other financial benefits. Contact us at 914-584-6720 or at
