Intelli-Hood Hiram College Retrofit

Posted on by Lindsey Burbee

Context

Like the majority of colleges and universities without kitchen demand control ventilation (DCV) in their dining halls, Hiram College was using inefficient hood fans to cool down their kitchens and to keep employees safe. Running at 100% capacity without any actual cooking occurring, the hood exhaust fans were wasting energy and pushing the meter higher and higher. As a consequence, Hiram experienced expensive utility bills. Below is the operation information for the kitchens:

  • Total motor power: 12. HP
  • Daily operating hours: 17
  • Days per week: 7
  • Weeks per year: 52
  • Cost per kilowatt hour: $.09
  • Climate zone: 5

 

Results

Hiram pursued Brewer-Garrett (BG), a performance contractor for energy efficiency, to consult them in energy efficiency upgrades. BG evaluated their kitchens and cafeterias to identify four areas with high energy consumption. BG recommended four Energy Conservation Measures (ECMs) for these spaces, all of which fell into their 15 year ROI program. Having seen successful ROI performance with Intelli-Hood kitchen hood controls in previous projects, BG included the technology as 1 of 4 ECMs for Hiram.

The Brewer-Garrett team commented on their impression of Intelli-Hood and working with Melink:

“You guys have the optimal product for smoke sensing. The cooking sensing technology identifies heat and/or smoke more accurately than other manufacturers. Melink also provides a very thorough turnkey solution, which was very helpful.”

– Eric Betz, Brewer-Garrett, electrical engineering manager

“We appreciate the fast turnaround and positive purchase experience. Also, the Melink installers were courteous and knowledgeable. All Melink personnel were readily accessible and eager to help when called. As far as the system itself, it is well thought-out and high quality. The display is easy to read and use.  Also, I like the ability for Melink to remotely monitor and fine tune with their Remote Access service.”

– Jon Erdmann, Brewer-Garrett, senior project manager

Intelli-Hood Frankfurt Hotel Retrofit Case Study

Posted on by Lindsey Burbee

Context

In October 2012 the Radison Blu Hotel in Frankfurt installed their first Melink Intelli-Hood system. Following the success of this project another 7 installations followed throughout Germany, Switzerland, Austria and Poland. Additional opportunities in the portfolio are being reviewed as a result of the energy savings being realized at the existing properties. There is an established and dedicated network throughout Europe to ensure project support from concept to completion for commercial kitchen operations.

Intelli-Hood University New Construction Case Study

Posted on by Lindsey Burbee

CONTEXT

In an effort to reach Miami University’s goal of a 20 percent reduction in both energy and CO² emissions, the new Armstrong Student Center Construction Team was working hard to achieve a LEED Silver rating. With a target opening date of February 2014, technologies were sought to optimize energy usage for each of the five dining stations within the center. Intelli-Hood® was selected because of it’s savings projections and successful performance in other Miami University dining halls. Below is the compiled kitchen operation data across the five dining stations in which Intelli-Hood was installed:

  • Total motor power: 56.5 HP
  • Daily operating hours: 17
  • Days per week: 7
  • Weeks per year: 52
  • Cost per kilowatt hour: $0.05
  • Climate zone: 5

RESULTS

The Miami University Facilities team avoided using 254,794 kilowatts and spending $65 thousand dollars in utility costs as a result of installing Intelli-Hood. They also and reduced their carbon footprint by 341,424 pounds. After presenting a year’s worth of data for all building systems, the Armstrong Center was rated as LEED Silver by the United States Green Building Council in October 2016.

Below are two sample graphs of the varying exhaust fan speed for one day at two separate dining stations:

The team at Miami University commented on their impression of Intelli-Hood and Melink:

“Working with Melink and their Intelli-Hood system has been nothing but
a good experience. They know what they are talking about and walked us
through the entire process.”

– Eric Yung, Miami University, Executive Chef

“We’re experiencing energy savings with no interruption to
kitchen operations. All our staff needs to do is turn on the
lights and occasionally clean.”

– John Pittman, Miami University, Food Service Operations

Intelli-Hood Stadium Retrofit Case Study

Posted on by Lindsey Burbee

CONTEXT

Faced with the industry challenge to reduce operating costs, Gillette
Stadium sought after promising opportunities to reduce energy usage.
Other stadiums in the country had selected Demand Control Kitchen
Ventilation (DCKV) for their kitchen hoods based on promising estimated
savings and available utility incentives. The Gillette Stadium team also
decided to take advantage of the opportunity.

  • Total motor power: 41 HP
  • Daily operating hours: 14
  • Days per week: 7
  • Weeks per year: 50
  • Cost per kilowatt hour: $0.10
  • Climate zone: Marine

RESULTS

Gillette Stadium selected Intelli-Hood® to be installed into the hoods in
the Club and Players kitchens. The team capitalized on utility rebate
incentives that expedited the payback projection by 1.5 years. After
operating for some time, the two kitchens were tested and proved to
have reduced exhaust fan speed dramatically. In the Players kitchen the
fan speed was reduced by 66 percent and in the Club kitchen the speed was
reduced by 55 percent. Combined, the average fan speed across both kitchens was 60 percent.

Intelli-Hood Restaurant Retrofit Case Study

Posted on by Lindsey Burbee

CONTEXT

A popular national restaurant chain, which also is a leader in sustainability, adopted Melink’s patented Intelli­-Hood® HVAC controls package as an energy conservation measure. The company’s goal was to achieve a 60 percent reduction in exhaust fan energy across its 80 properties. Following is an excerpt from its 2016 Corporate Sustainability Report:

“We tested an innovative demand ventilation system at our restaurant in Pleasanton, CA, which automatically adjusts the exhaust and make up air fan speed by measuring the temperature, steam and smoke in the hood. By having the fan speed ramp up or down as needed, the amount of energy used compared to standard fans is significantly reduced by as high as 60 percent. We are now in the process of rolling out the system to approximately 120 locations, potentially reducing our energy use by as much as 63,000 kWh’s per location.”

RESULTS

Savings across the restaurant company’s portfolio have been impressive and exceeded expectations. Not only has the company enjoyed increased operating profit as a result of the 65 percent reduction in energy usage, but its utility bill has dropped by $702,240 annually since 2015.
