Kudrinko’s achieves first Canadian Grocery Stewardship Certification

Kudrinko’s Ltd., an independent grocer in Westport, Ontario, is the first Canadian store to achieve Grocery Stewardship Certification from the Massachusetts-based Manomet Center for Conservation Sciences. Since 2007, the owners have reduced energy costs by 40 percent through reductions in electricity and heating fuel and CO2 emissions by 60 percent.

Neil Kudrinko, the co-owner of the 929 square-metre store, said the efforts were “driven by recognizing that sustainability is connected to our long-term success as a company.” As energy prices crept upwards in the early 2000s, Kudrinko understood that energy conservation would be the best long-term sustainable business plan. “Remaining competitive forced us to look at all aspects of our business, including energy,” he said.

Tackling the high-hanging fruit first leads to big savings

Kudrinko’s approach to energy conservation, however, departed from the conventional. He tackled the ‘high-hanging fruit’ first. “We decided to make the commitment to energy efficiency by putting the necessary resources in place.”

The energy-saving measures implemented by Kudrinko’s include the following:

To achieve Grocery Stewardship Certification, stores must demonstrate good practices in

  • energy efficiency
  • chemical usage
  • storm water impacts
  • waste reduction
  • employee engagement
  • water conservation
  • Inefficient compressors and the HVAC system were replaced with highly efficient models.
  • A custom-built heat recovery coil was installed on freezers to redirect excess heat into the store.
  • A remote controller unit was installed to monitor the temperature in all display cases to adjust for the optimum refrigerant quantity.
  • New dairy and meat cases were installed with glass doors, LED lighting, and night-time roller shades. The new cases are 80 percent more efficient than the old ones and hold more product.
  • Parking lot LED lighting is powered by a solar collector – the first installation of its kind in Canada.
  • The store’s lighting fixtures are being replaced with efficient LED fixtures as part of an ongoing lighting retrofit that will see freezer lights replaced soon.

The retrofits involved a $600,000 investment for the first phase, with an amortization of 15 years, and a $200,000 investment for the second phase, with an amortization of 12 years and a payback of about 8 years. These have enabled the store to cut its energy costs by 40 percent. “Investments like this allow us to continue to deliver competitive pricing to our customers,” Kudrinko notes.

Kudrinko’s $800,000 investment led to an emissions reduction of 120 tonnes!

Kudrinko says that by starting with capital-intensive projects, employees could see that energy efficiency was a priority and understand the benefits. “They are now on board, taking initiative and providing energy-saving ideas; energy efficiency has become part of the culture in the store.”


Kudrinko’s continues to save with energy management best practices

In addition to the retrofits, Kudrinko has also started tracking water consumption, is actively working to reduce waste from his store, and is involved in community sustainability projects.

Kudrinko has been benchmarking CO2 emissions with CarbonCounted since 2007 and says that this type of benchmarking helped launch and sustain the retrofits at the store. When he started benchmarking, store emissions were at 194 tonnes. By 2014, this figure had dropped to 74 tonnes thanks to the retrofitting measures. “I am hopeful that with this recent round of retrofits, there will be another 4-tonne reduction in emissions.”

Energy benchmarking is an important tool in the path to energy efficiency in the food retail sector as it provides data that can identify poorly performing buildings, point to strategic energy efficiency investments and track the effectiveness of the improvements undertaken. Those new to the concept of energy benchmarking can visit the following links to learn more about this important energy management best practice and the benefits of benchmarking store energy consumption.

Benchmarking can be done with the free online ENERGY STAR Portfolio Manager tool, which provides an energy use baseline and a statistically valid benchmark created specifically for Canadian supermarkets and other food retailers. With the release of Natural Resources Canada’s newest ENERGY STAR score, supermarkets and food stores across Canada can now rank their energy-efficiency performance against other similar competitors. Training on the tool through webinars is available to help new users get started on energy benchmarking.

CANMET lab makes AIA Environment Top Ten list

“We like how the different elevations address the climatic response. It is a thoughtful building, and not the typical sort that attains high performance. The interiors were very carefully resolved, with a clean, elegant, and obviously functional approach. This is probably a very economical building. There was thought put into solar control, the solar thermal space and photovoltaic systems. The displacement ventilation system in the office and laboratory spaces saves energy and provides comfort.”
(Jury comments)

The CANMET Materials Technology Laboratory in Hamilton, Ontario, has garnered a spot on the American Institute of Architects (AIA) Committee on the Environment Top Ten projects list. The lab is also the third Canadian research lab to achieve LEED Platinum certification, which it earned in 2013.

In pursuing its LEED certification, the building team launched an Integrated Design Process (IDP), which led to a 77-percent reduction in energy use compared to similar labs – a particularly challenging achievement for an industrial lab. This accomplishment puts the project well ahead of its energy reduction goal of 50 percent by 2030.

The impressive energy savings were achieved through a multitude of design features including in-slab radiant heating and cooling throughout the 16,193-square-metre building, displacement ventilation, and heat recovery from ventilation air and process water.

The building team installed a solar wall as well as a solar system composed of 209 collectors to satisfy radiant heating and hot water needs. Thermal heat is stored in solar tanks with total storage capacity of 40,000 gallons. Any excess thermal or process heat goes to the 152 metre deep, 80-well on-site geo-exchange system that contributes to low-grade heating.

The IDP team studied and modelled the micro-climate to create the best design for the site. They identified that high-bay labs generate a lot of heat, therefore they were relocated to the north side of the building. With a large south-facing roof surface to exploit, the building was also primed to take full advantage of renewable solar energy sourcing. The lab features a high-performance thermal skin, triple-glazed windows, R-20 walls and an R-32 roof with a 24-percent window-to-wall ratio. Daylight and occupancy sensors control lighting and blinds to reduce energy use.

A sophisticated Building Automation System (BAS), which ties into sub-meters on major equipment or processes, allows operators to track energy use for benchmarking and improvement.

The end result is a 48-percent energy savings over the Model National Energy Code for Buildings (MNECB) standards.

The end result is a 48-percent energy savings over the Model National Energy Code for Buildings (MNECB) standards. The process made a fully integrated, energy efficient and cost-effective design possible. The IDP allowed for effective decision-making with regular meetings based on transparency, communication and the development of an extensive knowledge base.

An update from the national Survey of Commercial and Institutional Energy Use

The national Survey of Commercial and Institutional Energy Use (SCIEU) 2014, as conducted by Statistics Canada on behalf of Natural Resources Canada (NRCan), is at its mid-point in data collection. The current SCIEU was launched in the second week of February 2015 and is gathering data for the 2014 calendar year.

The survey is conducted every five years to collect detailed information on the energy demand and consumption patterns of Canadian organizations and institutions, their buildings and establishments. The last one was conducted in 2010 and collected data for calendar year 2009.

The results of this survey, which will be completed by September 2015, will be released in 2016 and used by utilities, as well as provincial and federal governments, to develop programs and policies that will improve the energy efficiency of commercial and institutional buildings in Canada. The results of the survey will also provide current energy use data to NRCan to update existing ENERGY STAR performance scores as well as to develop new scores for building types that do not yet have them.
