Getting a clear picture on how building systems are performing is the first step to manage your energy. Our innovative energy products and solutions give real-time visibility of energy including electricity, gas and water usage, helping to optimize system performance and validate savings.

Environmental Sustainability

The environment is our core focus. We are working to facilitate the adoption of low or carbon neutral opportunities to help you take charge of your economic future. Our mandate is to reduce emissions, create jobs and support a strong and sustainable local economy.

Who are our clients

We provide services to all industry sectors throughout Canada and the United States. Satisfying the individual needs of each one of our Clients is important to us.



Risk of equipment downtime and loss of product or operational ability can be a bottom line game changer in the Commercial/Industrial Sector. Our real-time performance analysis and continual monitoring will provide insight into equipment operation to allow for pre-emptive maintenance and capital planning for equipment upgrades or replacement.



North American Manufacturers are under pressure to reduce GHG emissions and adopt Industry 4.0 digital and clean technologies. We are at the forefront of this revolution to support the transition to low carbon technologies and smart processes which increase productivity and facilitate economic competitiveness.



The MASH sector is always exploring new ways to reduce operating costs and use energy more efficiently. We work closely with this sector to target energy management strategies, reduce energy wastage and free up funds that can be better spent on essential improvements and services.



Our focus is to help Building Owners manage their energy and water costs through monitoring and reporting. This will comply with legislation such as Ontario’s Energy and Water Reporting and Benchmarking Law, cut electricity, gas and water costs and reduce carbon emissions. A win for both owners, tenants and the environment.

Our Focus

“When performance is measured, performance improves. When performance is measured and reported back, the rate of improvement accelerates." - Pearson’s Law

Heating and Cooling

Our energy performance analysis solution gives you real-time visibility into the ‘blackbox’ of Heating, Ventilation, Air Conditioning and Refrigeration (HVAC/R) systems. System optimization and reduced energy consumption will guarantee savings of 10-40%!

Energy Solutions

We take the worry out of managing your energy. Our team of professionals understand Systems, finance and energy which means we will create an Energy Management solution that suits all of your individual needs.


Do you need to get the big picture on how your energy is being used? Monitoring and Targeting is the answer. Monitoring your usage in real-time will help you manage inefficiencies and wastage and drive energy savings long term.


Through Commissioning we will ensure that new Systems are installed, setup and properly functional and operating efficiently. Through our Re-Commissioning we will baseline and optimize existing equipment operation . Our goal is to work with you on all of your building Systems to achieve rewarding results.

Our Services

All of our offerings are based on a continual improvement framework that incorporates Energy Management into everyday practices and encompasses the principle of the proven Plan-Do-Check-Act (PDCA) business model. All Renteknik’s projects are based on a (PMAIR) cycle: (P) project planning, (MA) realtime monitoring and analysis, (I) improvement/change identification and implementation support and (R) reporting on verification of achieved savings and/ or next steps. Continual improvement will increase staff and operational productivity, reduce downtime, reduce costs, increase quality and profitability.

Industry Updates

The Energy Industry is constantly changing. We are actively researching different technologies, solutions and programs that will help businesses take control of their energy.

Uncovering new opportunities that suit your business needs will save energy, improve operational efficiency and support business growth and profitability through cost savings and increased productivity.

BioScrub EFM
Game Changing HVAC Probiotic Coil Cleaning

Standard Coil cleaning methods use harsh chemicals and only provide surface cleaning. The BioScrub EFM Patented Probiotic Coil Cleaning Process is a proprietary EPA-rated and environmentally safe HVAC coil cleaning process. Cleaning of RTUs, AHUs and Cooling Towers have shown positive performance results through M&V testing including:

  • Humidity (Rh) and temperature delta increases
  • Increased air flow through Coils
  • Overall efficiency gain of 20-40%
  • Lower direct energy costs
  • Improved indoor air quality
  • Improved Tenant comfort

Energy Management Information Systems (EMIS)
Improving Energy Efficiency

Generally, most businesses have to sell $10 worth of product to make $1 of profit. Every $1,000 we save through energy efficiency improvements and energy reduction is the equivalent to $10,000 in sales. To achieve this goal, our Energy Management solution follows Renteknik’s PMAIR cycle. We audit, monitor and analyze all energy contributing factors. Implementation and targets are realistically set to ensure commitment on all levels of the organization. Frequent reporting on energy and business related benefits also ensures a successful EMIS. Funding is also available to assist with Projects.

Wireless Submetering
Taking Control Of Your Energy

“Energy is a variable operating cost, not a fixed overhead charge.”
Our Energy Management solution uses Best in Class technology. Centrica’s patented wireless sensors combine cloud-based real-time analytics to collect energy consumption data and identify excess energy usage at device level and improve facility operations. The Energy Insight sensors are selfpowered and designed for noninvasive installation. A simple snap onto existing electrical wires, a remote wireless bridge and an internet connection is all that is needed to get the real-time data that can be integrated into an EMIS Project.
