Beware of losing your building's Energy Star standing as updates loom ahead

Read the original article by Josh Richards at

Conserving energy has expanded beyond the realm of social and corporate responsibility. For many employers, sustainable practices are a necessity to attract and retain the best labor. At those firms, workers may expect their employers and workplaces to earn and display Energy Star, LEED and other certifications to demonstrate good stewardship of natural resources.

However, some properties might be at risk of losing at least one of those credentials.

Later this year, some buildings certified under the Energy Star program likely will lose that certification after the release of updated building performance baselines. Fortunately, landlords can act now to begin improving the metrics tracked in Energy Star’s online Portfolio Manager tool and put their properties on a path to qualify for the program’s mark of approval even after the change.

Why the reset?

For most commercial properties, an Energy Star score ranging from 1 to 100 indicates how well the property compares with a sampling of thousands of buildings represented in the Commercial Buildings Energy Consumption Survey. The Energy Information Administration, which collects and analyzes energy statistics for the U.S. government, conducts the survey every four to six years. The Environmental Protection Agency (EPA) uses survey data to build statistically representative models for various building types. 

When an Energy Star participant submits energy-usage performance data collected through Portfolio Manager, the EPA converts that information into a numerical Energy Star score showing how well the building performs in relation to models of its peers. Buildings that achieve a 75 or higher generally qualify for Energy Star certification as energy-efficient.

For several years, the EPA has relied on survey data collected in 2003 to calculate Energy Star scores. At the time of that survey, Energy Star was still gaining momentum on its way to becoming an industry standard for measuring and reducing energy consumption. Recently, however, the agency has been updating Portfolio Manager with survey data collected in 2012.

In the decade between the surveys, the use of Portfolio Manager mushroomed, as did the number of commercial buildings adopting various energy-conservation programs. That suggests the new data set will include a larger proportion of energy-efficient buildings. As a result, a building that achieved the Energy Star label in the past may not compare as well to buildings in the new data set, and could see its score fall due to a lower relative standing even if the property’s performance remains unchanged.

The EPA plans to publish updated scores based on the newer survey in August. While there is no way to predict the change in score for a specific property, building owners should be prepared for a drop of at least five points in their Energy Star score. Buildings certified with scores of 75 to 80, therefore, are most at risk of losing certification 

What's at stake?

It’s important for property owners to remember that Energy Star scores are a mark of relative performance. Actual performance measured in Portfolio Manager is unaffected by the update in survey data.

Improvements achieved through conservation programs continue to benefit the property’s owner and occupants, and can include less-intensive electricity usage, lower utility bills, a healthier workplace that maximizes natural light, and in some cases, reductions in water consumption and waste generation. These worthwhile programs will continue to save money and improve an asset’s appeal to tenants and investors.

Owners and tenants whose downgraded scores result in the loss of Energy Star certification will lose the marketing benefits that come with this seal of approval from the EPA, potentially lowering their competitive advantage in attracting and retaining tenants. Employers who consider Energy Star a requirement for their space may look to other properties in a site search, or if they are already a tenant in the building, may let their leases expire. 


In most cases, the first phase of energy conservation will have captured the low-hanging fruit of reducing weekend operations, optimizing equipment run schedules or converting some lights to fluorescent. Sustainability advisers can help landlords map out strategies to further reduce energy consumption. 

Deeper cuts in power usage are more likely to require larger capital investments for items such as high-efficiency light fixtures and mechanical equipment. Yet many landlords will decide that achieving greater efficiency is worth the monetary cost. Becoming educated on the costs and benefits of improvements may be more important than ever. 

We are entering a new phase in energy conservation where the goal may be more than a lower utility bill. Landlords and tenants are collaborating to forge a workplace that is grounded in the tenets of sustainability and a source of employee pride.

Guest Column: Using a Hybrid Car for Storm Resilience


Storm after storm, including the two nor’easters we’ve experienced in Connecticut over the past week, Mother Nature continues to show us that even though it is critical to focus on energy-efficient building designs and renewable energy systems, we must also include storm resiliency as another component of designing truly sustainable buildings.

While traditional portable gasoline generators are widely available to provide emergency back-up electricity to a home in the event of a power outage, these don’t necessarily scream “sustainable”.

A few years ago, after suffering a hurricane related power outage in Connecticut, I decided to take up a somewhat unique precaution against potential electrical power outages. While I am able to generate 100% of my annual electricity through solar PV panels, it was not cost effective to buy batteries just for the sake of a power outage. I instead chose to outfit my hybrid car to serve as a back-up generator to my house in New Haven.

This approach relies on an inverter, which I purchased from ConVerdant Vehicles*, which happened to be less expensive (~$700) than a standard gas generator. It required a quick and inexpensive (~$100) modification to my car by a mechanic and the installation of a traditional generator transfer switch in my garage, which was done by an electrician (~$500).

In the event of a power outage, I simply disconnect my house from the grid, move my car outdoors, hook up the inverter to the car and transfer switch, and start the car up. The whole process takes me less than 10 minutes. The inverter generates enough electricity (~1,600 Watts) to run the critical circuits in my house, including pre-selected lights, refrigerator, and the electric ignition to the tankless gas water heater, and even a few not-so-critical circuits, like the cable box/modem and TV.

This approach is more “sustainable” since it takes advantage of my hybrid’s efficient engine to provide electricity with half the fuel of a traditional generator, and is much much quieter.

I was not prepared for our first power outage in Connecticut, but we were able to use the gas stove for cooking and our gas fireplace kept the first floor at well over 70F. Being without a fridge and hot water was a challenge though. Now that we have the inverter, being able to provide basic power for three days on just one tank of gas makes me feel good about my home being energy-efficient and sustainable, even during a storm.

*While ConVerdant is no longer selling the inverters, other inverters are available, but perhaps at smaller capacities.

Bridgeport Installs State's First Microgrid Generator


BRIDGEPORT, CT — From the City of Bridgeport: Mayor Ganim and City officials today flipped the switch on a first-of-its-kind 'microgrid' generator that will supply cleaner energy to power City Hall, Police Headquarters, and the Eisenhower Senior Center. The microgrid project is a standalone power generation system providing uninterrupted, environmentally friendly and reliable power to all three facilities. (See the video below)

This project combines a new traditional natural gas reciprocating generator that can run around the clock with a microgrid distribution system. While the generator will use less fuel to make a comparable amount of energy and emit fewer emissions through higher conversion efficiencies, the microgrid will provide foolproof power in the case of a blackout or inclement weather.

"This project has been in the works for a long time and we are excited to be able to see it come to fruition," said Mayor Ganim "It is an important step towards making Bridgeport a resilient city with the benefit of being more sustainable and environmentally conscious. The microgrid propels us forward in our progress for more resourceful and effective ways to be energy efficient. As an added benefit, the microgrid will provide security in knowing that the City will be able to operate at full capacity in the event of a power outage."

Not only will the microgrid generator provide power, the excess heat will be used to provide a significant amount of heating and cooling to these government buildings. In addition, the system gives the city the option to expand in the future to other vital city buildings like the Margaret E. Morton building, Fire Headquarters, and even non-city buildings in the event future regulation or market factors make this viable.

The Bridgeport Microgrid is a partnership between Controlled Air, Inc., OR&L Construction, and Power Island Energy with a design assist and professional services from BL Companies. The project is a part of a municipal pilot program launched through the State Department of Energy and Environmental Protection in 2013. Key Bank was the principle financier with secondary financing from CT Green Bank and grants through DEEP.

LEED for Cities grant program unveiled

The U.S. Green Building Council (USGBC), creators of the LEED (Leadership in Energy & Environmental Design) green building program, with support from the Bank of America Charitable Foundation, have announced a new grant program designed to recognize the sustainability and green building achievements of U.S. cities pursuing LEED for Cities certification.

Initial grant recipients include San Jose, Calif.; Denver, Colo.; Phoenix; Atlanta; Washington, D.C.; and Chicago. Each grant will consist of financial assistance to aid in the pursuit of LEED for Cities certification, educational resources and customized technical support, according to a release.

LEED for Cities enables local governments to measure and track citywide performance by focusing on outcomes, rather than intent. Cities are evaluated across 14 key metrics, including energy, water, waste, transportation, education, health, safety and equitability. Washington, D.C., and Phoenix are the first cities to achieve certification through the program and earned LEED platinum, the highest level of certification.

“A sustainable city not only focuses on the environmental footprint but also how it is working to provide a better quality of life for its residents,” said Mahesh Ramanujam, president and CEO of the USGBC. “LEED has been a transformative tool for buildings, and we are taking what we learned and applying it to help cities achieve a higher level of performance. LEED for Cities helps tell a sustainability story in a way that encourages a city’s citizens to be more engaged, and with the support of the Bank of America Charitable Foundation, these six grant recipients are committing to delivering a more sustainable future today.”

The Bank of America Charitable Foundation previously supported the Affordable Green Neighborhoods Program, which, starting in 2010, provided assistance to eligible nonprofit and public sector developers of affordable housing to ensure that every new unit of affordable housing meets the highest standards of sustainability and offers residents the healthiest communities possible. The LEED for Cities grant program provides entire cities with the financial and educational support to improve performance over time through the pursuit of LEED for Cities certification.

Performance for cities is continuously tracked through Arc, the digital platform that connects all sustainability progress in one place and generates a performance score between 0 and 100. There are a total of 25 cities participating in LEED for Cities globally.
