Higher Education Taking Action Against Climate Change

Climate change has been a hot topic recently, and higher education is taking note and taking action. While hundreds of schools have already made pledges to increase sustainability across their campus, 13 schools are taking the lead and taking it a step farther. At this year’s 2018 Higher Education Climate Leadership Summit, 13 North American research universities launched the University Climate Change Coalition, or UC3, a group committed to implementing green initiatives into their own campuses and leveraging their research and experience to help others do the same. For over a decade, these universities have been researching innovative ways to reduce energy consumption, and educating students on how to combat climate challenges that are quickly approaching, but now they taking it a step further to spread this expertise to accelerate change through all of higher education.

As the first school listed on the Campus Carbon Neutrality commitment, Cornell University paved the way. They have made continual efforts to implement Energy Conservation Initiatives (ECI), committing $33M towards ECI’s over a recent 5-year period. The Ohio State University established goals to be carbon neutral by 2050 and to reduce total campus building energy consumption by 25%. Both of these schools have found ways to lessen their carbon footprint by implementing various sustainability practices and products campus wide. Reducing energy use in existing buildings have been an ongoing initiative by both universities focusing on modernizing building envelopes, implementation of building automation and control systems, heat recovery and lighting systems. Cornell states projects they’ve implemented to date have had a return on investment of five to seven years.

A place that can often be overlooked, but has a great impact, is the ventilation system in campus kitchens. With the demand of long hours to accommodate various student schedules, and high volume because of the dense population, campus kitchens tend to run a majority of the day. Depending where the university is located, various local and state codes may require fans to operate 24/7 if the site utilizes gas pilots on kitchen equipment which remain on overnight. The HVAC systems account for 29% of the energy consumption of a food service area, with up to 75% of this load able to be attributed to the commercial kitchen ventilation system.

Melink is the innovator of Demand Control Kitchen Ventilation (DCKV) with the Intelli-Hood® system. Both Cornell University and The Ohio State University found the benefit of utilizing dckv systems across a majority of their kitchens. Using Intelli-Hood®, systems operate at a lower overall fans speed average. In an average day, the Melink Intelli-Hood system can recognize up to a 45% reduction in fan speeds equivalent to approximately 83% electrical fan energy savings. Additionally, this reduced operation results in a decrease of load demand of surrounding HVAC equipment providing additional conditioned air savings that can be recognized.

Melink Corporation Awarded GSA Certification To Work Directly With U.S. Government Agencies

CINCINNATI, OH – Melink Corporation, a global provider of energy efficiency and renewable energy solutions, just announced it has been awarded a General Services Administration (GSA) Multiple Award Services 056 Contract. This 5-year contract will enable Melink Corporation to partner directly with U.S. government agencies to deliver Intelli-Hood®, their proprietary kitchen ventilation controls, for increased energy efficiency in cooking operations. .

Tax Reform Bill Windfall – Reinvest In Efficient Operations for the Long Haul

Your profits just increased 14%, what are you going to do with all that cash???

Large US companies are on tap to reap the benefits of a 21% corporate tax, down from 35% (not factoring in Effective Tax Rates), under the new federal tax bill and there are many theories on where the money will go. Several companies have already given out bonuses, announced minimum wage increases, increased 401k matches, stock buyback programs, and increased shareholder dividends.  While all these are great short term shots in the arm during a time of robust economic growth, I’d like to argue that the smart play would be to invest in operational and energy efficiencies to prepare for an economic pullback and eventual awakening of the bears. Fortunately for many companies this recent time of growth has come over a period in which energy prices have been relatively flat ,or declining, resulting in reduced expenses and increased profit margins.  The rates for natural gas are slightly above 10-year lows and electrical pricing has shown a modest increase of 3% on average across the United States (https://www.electricchoice.com/electricity-prices-by-state). It would be short sided and foolish to think these rates will remain near basement levels for the long-term as geo-political flash points or natural disasters could lead to sharp increases in rates. Unless businesses invest in efficiency now they’re not going to be able to react fast enough to counter the cost of an increase should an event occur or prices quickly rebound.

Therefore, the smart money will point toward investing in efficiency projects now in favorable capital markets. Aside from some newly minted Bitcoin millionaires, my bet is that most “Main Street Americans” would rest easy at night knowing their investment will yield a consistent return north of 30%. There’s likely not one silver bullet technology that will drastically improve operational efficiencies, however there are many proven low risk investments such as LED lighting, HVAC upgrades, Building Management Systems, and smart building controls that can have an impact on many areas of your operations. This multi-faceted approach to energy efficiency will build a more robust infrastructure and predictable energy usage profile for business operator for when the economy eventually pulls back and rates increase. I’m not an economist, investment banker, trader, or tax analyst, but I do manage a global business and believe in growth reinvestment balanced with the protection of downside risk.  So, if you’re a building owner, asset manager, facility manager or responsible for the financial performance of your business; I urge you to mitigate your future operations cost risk and invest in efficiency today.

Higher Education Dining Trends Impact On Energy Usage

The dining experience at Colleges and Universities across the country has changed drastically over the last decade. Although it has been about ten years since I left, it feels like just yesterday I was on campus at the University of Cincinnati and Northern Kentucky University. During my tenure, the options were limited; you might find a handful of cafeterias across campus and a few popular fast food places like Wendy’s, Subway and Pizza Hut at the student union. Visiting campus now I can’t believe the changes; there are hundreds of options. The student unions have started to look more and more like casino food courts that include local options and big names. Students are seriously taking food offerings into account when considering a school, especially if they’re going to live on campus. Colleges are majorly using it to their advantage to recruit students and provide a better campus life. In 2008, NKU even constructed a new Student Union Building to compete with other local area colleges.

Over the last 7 years or so, I’ve toured dozens of higher education kitchens and the cooking operations are huge. West Point, for example, serves around 5,000 meals in a very short amount of time on any given day. All the Big 10 schools have between 7 and 10 dining halls on campus that are running for 3+ meals a day and serving a variety of options from soups and chili to baby-back ribs. With the large operations come large costs! Not just in the obvious costs including wages, salaries, and benefits, but in big time energy usage. Running the exhaust fans and the corresponding MUA units 16+ hours per day is a ton of wasted electricity. Additionally, the number of commercial exhaust hoods required to prepare the diverse food preparation means there is a ton of exhausted air and reconditioning of air required.

As schools continue to compete for higher enrollment rates and evolve with demand, they have to respond to the increased energy usage and operating expenses to ensure they can remain competitive with pricing. Many colleges and universities have tight operating budgets for their facilities, so it’s especially important to find low or no-cost ways to reduce energy expenditures. To combat these new challenges, Campus Energy Managers have started considering Demand-Controlled Kitchen Ventilation (DCKV) systems to help save the electric energy being wasted on all the new fan motors and reconditioned air. These systems conserve energy, save money and make for a quieter and more comfortable cooking experience.  Energy Managers have also started engaging students and faculty in energy conservation to save on campus energy bills. At many higher education institutions, students are the biggest advocates for energy efficiency and will respond enthusiastically to educational initiatives and conservation pledge campaigns.

Lodging’s Consumer Dining Trends and Your HVAC System

Since 2010, the hotel landscape has changed drastically due to the emergence of Millennials in the marketplace. The days of long-term consistency, home-away-from-home value, and a friendly face at check-in are things of the past, and we are now seeing the need for hotel hot spots that are personalized, efficient, connected and trendy. The transformation makes hotels get creative in filling revenue discrepancies created by the quickly changing landscape, focusing more than ever on operational costs.

The change in buying power

Prior to 2010, the “Baby-Boomers” generation dominated occupancy demands. When Boomers were the bulk of the lodging customer base, focus was on consistency, more value for the customer’s dollar, a big screen TV, consistent food and beverage offerings, and a friendly, personalized check-in experience. Today, Millennials are all about Individualism, efficiency, mobile connectivity, creative and trendy food and beverage offerings, and online check-in. Due to this demand shift, along with the cost to build and the ever-changing consumer marketplace, developers are becoming more focused on the development of limited brand hotels. As of June 2017, “Upscale” and “Upper Mid-Scale” represent roughly 65% of all new build hotels.

In response to the change in customer wants and needs, hotels have majorly changed their strategy. Hilton developed the Tru® brand in response to these changes to make it easier and less expensive for developers to build. Marriott is doing an over-haul of their Courtyard® brand to create a hybrid solution to please guests from both generations. Previously, if you’d go to a major brand hotel on the east coast or the west coast, you could get the same exact cheeseburger. Those days are over! Hotels must now bring in local food and beverage options to not only keep customers eating at the hotels, but to provide a truly exceptional experience every time. A satisfied customer is no longer enough in any market today. With social media and other technologies, there’s now a need to “wow” customers. A good dining experience isn’t enough, it needs to be one of the best dining experiences they’ve ever had!

What does this mean for revenue?
In a recent article published by Lodging Magazine, Food and Beverage (F&B) profit margins are up roughly 5% since 2010, yet food purchases only rose by a CAGR of 2.3%. The two sources that continue to decline for F&B are “In-Room Dining” and “Mini-Bar” sales, which is consistent with the new emphasis of providing a unique social experience in hotel lobbies. Considering the decline in food purchases and the ever-changing marketplace, it is hard to imagine lodging has seen a 5% increase in F&B profit margins.

So how do all these items tie together and make for increased profit margins? How have the hotel management companies been able to make all these changes in a short amount of time and still increase profits? How can profit margins be up when we all know an ever-changing menu would make it harder to negotiate prices at a high-volume? It’s not one simple answer but I’ve personally seen the major management companies stepping up their game and working smarter. Revenue increases can’t be the main driver for the success. The operational efficiencies are where the differences are made!

Changing energy consumption is key

Electrical consumption for the typical US hotel is 50% in HVAC and 23% in lighting. Within food service facilities, HVAC systems account for 29% of energy consumption. Up to 75% of this load can be attributed to the commercial kitchen ventilation system. At Melink, we’ve seen many owners in the last 2 to 3 years begin installing a Demand Control Kitchen Ventilation (DCKV) system in their kitchens to help lower operational costs and solve the ever-plaguing negative air pressure issues. With the help of these owners and major brands, we’ve also developed technologies to help solve this in the ever-growing Select Service markets. Many of these projects have been packaged with LED lighting to solve 73% of the problem (per the chart below). This allows the hotel owner to take advantage of the available utility incentives, increase profit margins in the changing F&B market, show an attractive ROI to the owner, help solve air pressure issues in common spaces, and increase overall guest comfort.

If there’s one thing that’s true in this industry, it’s that change is inevitable! Management companies, owners, brands, developers, and vendors have two options: change with the market or get left behind. I’m happy to report that most of the major players are making smart and energy-conscious decisions that are ultimately improving their bottom line and increasing guest loyalty and satisfaction.

Intelli-Hood Case Study – Pala Casino Spa & Resort

CONTEXT

Pala Casino Spa & Resort has always been cognizant of their environmental footprint and the impact they make on the surrounding community. Continually looking for ways to improve, they recently conducted energy audits across the property to identify areas of improvement and develop an optimization plan. One of the top priorities was to address their kitchen ventilation system which consisted of 10 kitchens with hoods running at 100% a majority of the day. With Trane as their partner in this project, they decided to implement Melink Intelli-Hood® so their hoods would self-modulate as necessary according to the cooking conditions.

RESULTS

Pala Casino Spa & Resort was able to reduce their fan speed about 35%, resulting in a savings of $139,713 in the first year alone. Their return on investment also exceeded expectations, by returning their initial investment in under 2 years. With this improvement they were not only able reduce their immediate energy consumption, but they are able to use the Intelli-Hood technology to continually monitor their usage, and their kitchens became much quieter and more comfortable as well!

Intelli-Hood Military Base Retrofit Case Study

Context

In effort to evaluate the potential of Demand Control Kitchen Ventilation (DCKV) technology, the US Army Engineer Research and Development Center (ERDC) designed, executed, and evaluated a field study. Melink Intelli-Hood® was installed in four dining facilities at Department of Defense (DoD) locations in different climate zones across the United States. These kitchens typically serve a high volume of many meals in short time periods and are excellent candidates for DCKV kitchen controls equipment to reduce energy usage of kitchen hood fans. Baseline measurements were taken before the installations and the energy savings were determined after several months of data. There were two performance objectives: demonstrate a savings of at least 30% in energy usage and maintain or improve occupant comfort.

Results

Both performance objectives were achieved with all four dining facilities saving more than 30% in energy usage as well as maintaining comfort and noise level. No complaints were reported. Further, the following parameters were found to maximize ROI:

  • Relatively large exhaust hood systems (min. of 5,000 CFM)
  • Climate requiring significant heating and/or cooling of makeup air
  • Relatively long operating hours
  • Med-High utility costs

MILITARY DINING CASE STUDY RESULTS WITH INTELLIHOOD

The following is an excerpt from the ERDC report in section 8.3:

Procurement Considerations:
Some vendors offer systems that use only temperature sensors, i.e., they do not use optical or opacity sensors. This is not recommended since the opitcal sensors provide an indication of cooking when the exhaust air has not yet reached the set point temperature.  Thus, the hoods would continue to operate at a low exhaust rate and cooking effluent would spill from the exhaust hood. Temperature-only systems are usually set to higher exhaust rates to mitigate this issue.

The following is a summary table of the energy savings results:

Intelli-Hood Cincinnati Zoo Restaurant Retrofit

Context

Base Camp Cafe at the Cincinnati Zoo was due for a remodel project in 2013 and took the opportunity to retrofit the restaurant with environmentally sustainable features. They set the goal of achieving LEED Gold certification, but meeting the requirements posed much challenge. Below are the restaurant kitchen conditions:

  • Total motor power: 10 HP
  • Daily operating hours: 14
  • Days per week: 7
  • Weeks per year: 52
  • Cost per kilowatt hour: $.10
  • Climate zone: 5
  • Customers per year: 1.4 million

 

Results

The Cincinnati Zoo Sustainability Team chose to install Intelli-Hood Controls to gain credits toward their pursuit of a LEED Gold-certified cafe. The Zoo previously worked with Melink for a solar canopy project. Since 2013, Base Camp Cafe has been ranked the greenest restaurant in the nation, as measured by The Green Restaurant Association. This association granted them 473 points for the different green elements of their restaurant, with their energy reduction accounting for 220 points, or 47% of their score.

The facilities team at the Cincinnati Zoo commented on their impression of Intelli-Hood and working with Melink:

“I appreciate that Intelli-Hood is automated, it’s one less thing to worry about in managing a restaurant. We don’t have to remind people to turn it on and off. We get savings by letting the system run on it’s on.”
– Tony James, Cincinnati Zoo, Facilities Management

 

“Melink was detail-oriented and, to be honest, a lot more on-the-ball than we were. They were responsive to the fine-tuning issues that came about, such as sensors getting dirty with grease.”
– Greg Speidel, HGC Construction, Project Manager

 

“Restaurants are huge energy hogs, it’s also where you can get your money back.”
– Mark Fisher, Cincinnati Zoo, Director of Sustainability
