The Intelli-Hood system controls the ventilation fan speed, depending on the current conditions of the kitchen hoods. Temperature and optic sensors are used to detect heat and steam, and these sensors will change the fan speed accordingly. For Shake Shack, this saves about 64% of ventilation fan energy consumption. Reducing the fans from running 24 hours per day not only saves energy consumption from the extract and supply fans but also creates considerable heating and cooling savings.

Result

Shake Shack saw a quick return on their investment with a 1.4 year payback, saving $8,487 USD in the first year. With this system, the restaurant was not only able to reduce its immediate energy consumption by 57% but is able to use the technology to continually monitor usage and adjust as necessary.

Petrol Station Case Study

CONTEXT

APCO, a local family-owned petrol station, was focused on finding ways to reduce their operating costs and lessen the environmental impact by reducing the amount of fuels being burned to power their locations. They identified their kitchen ventilation as a place of improvement and decided to implement a demand control kitchen ventilation system to self- modulate fan speeds based on cooking activity.

SOLUTION

They chose ecosense powered by Melink Intelli-Hood because ecosense uses site-specific information combined with performance data from thousands of previously installed systems so system performance can be predicted accurately.

At first, they decided to run a pilot program to verify the system was a good fit. Based on excellent preliminary results they decided to install two more locations and quickly had the same success. In their first year they have saved over $45,000 AUD in energy savings by reducing their kitchen operating costs by 72%, securing their return on investment in just over a year!

University of Dayton

As part of its commitment to sustainability, the University of Dayton in Ohio became a fair trade university and was the first Catholic university in the nation to divest from fossil fuels. This means UD is committed to renovating or building campus facilities that source power from clean energy, while providing a greener campus in which their students can engage. Solar energy plays a key role.

 

 

Solar Solutions

In 2018, Melink Solar & Geo collaborated with UD to install two arrays, totaling a combined 4,026 panels with a capacity of 1.26 megawatts of power. A ground-mounted array was installed at Curran Place, and a roof-mounted array was installed at Fitz Hall. As part of a long-term power purchase agreement, Melink engineered and constructed the arrays, selling the generated electricity to the university.

The solar arrays provide nearly 10 percent of the power consumption of both buildings, as well as power electric car stations at each location. UD has the option to purchase the arrays after eight years. Students, faculty, and researchers participated in the installation of the modules and incorporated the sustainability project into research and curriculum.

The Merrion Hotel Case Study

The Merrion Hotel is a luxury resort located in Dublin, Ireland. The hotel has 123 guest rooms, 19 suites, event spaces, a spa, two bars, and two restaurants. Back-of-house includes two full kitchens that operate 24/7, 365 days per year.

Context

To help mitigate potential ventilation issues and to help control operating costs, the hotel decided to install a demand control kitchen ventilation system in one of the kitchens. Thus, an ENERGY STAR-rated Intelli-Hood kitchen hood controls system was installed by EFTECH, Melink’s distributor in Ireland. The Intelli-Hood system controls the ventilation fan speed, depending on the current conditions of the kitchen hoods. Temperature and optic sensors are used to detect heat and steam, and these sensors will change the fan speed accordingly. This saves, in the case of The Merrion Hotel, 38% of ventilation fan energy consumption. Reducing the fans from running 24 hours per day not only saves energy consumption from the
extract and supply fans but also creates considerable heating and cooling savings.

Result

The Merrion Hotel experienced a strong return on its Intelli-Hood investment: less than an 18-month payback, based on the recorded data. This further supports the case that 90% of lodging with on-site commercial kitchens can benefit from Intelli-Hood. The hotel was not only able to reduce its immediate energy consumption by 48% but is also able to use the technology to continually monitor usage and adjust
as necessary.

Correctional Facility Case Study

 

Melink’s Intelli-Hood® system is part of an Energy Savings Performance Contract (ESPC) with this California county jail, which houses 680 inmates.

ESPCs provide guaranteed energy savings in their contracts, so Melink’s customer (an engineering firm representing the facility) was on the hook for the proposed energy savings.

Because Melink uses site-specific information combined with performance data from hundreds of previously installed Intelli-Hood systems, system performance can be predicted accurately.

Melink also ensures its estimates are conservative so as not to “oversell” savings, especially in a case like this where the customer is responsible for guaranteed savings. Melink “undersold” and over-delivered on energy savings for the county jail.

Case Study: Retail New Construction

Context

A national retail chain experienced rapid growth, adding 70 new locations in a span of 10 weeks to keep up with demand. Melink performed full testing, balancing, and commissioning at each location, which included providing detailed reports for each site. This allowed the customer to resolve punchlist items under warranty, hold contractors accountable to their work, and open the stores on time.

 

Sample of Findings

 

 

Results

 

 

Melink completed all 70 locations in 10 weeks and found a total of 594 punchlist items, which averaged approximately eight per location. By catching these issues before they became serious problems, it led to reduced customer and store complaints, as well as a 15% decrease in maintenance calls and an estimated 60% decrease in maintenance costs over the first 12 months. In addition, the retailer had an estimated ROI on its commissioning program within 18 months of the new openings. The fast-paced schedule allowed the retailer to open each location on time and fully balanced.

Case Study: HVAC Equipment Assessment

Context

A multi-level building, consisting of medical offices, had no pre-existing
mechanical plans of its facility when a new management firm took ownership. With tenants practicing various medical fields and a stream of daily visitors to the building, the new owner needed to ensure that the ductwork and airflow were verified and running properly. Proper ventilation can help prevent the spread of airborne pathogens and other health risks.

Melink created a detailed schedule for the full project and each individual office suite. This schedule provided tenants with sufficient notice for Melink’s technicians to easily gain access to perform the commissioning services.

Results

 

Melink completed the detailed documentation of the ductwork for the office building’s HVAC and exhaust systems, which included noting all the sizes and equipment locations for each floor and suite. This report also noted abandoned and disconnected units located above the ceilings.

Ultimately, the initial assessment of existing equipment that took place in 2019 led to scheduling a second phase of the project: rebalancing and changes to the building’s layout to be completed in early 2022.
