• Energy audits for commercial, institutional, and industrial buildings.
  • Data logging of temperatures, motor operational schedules, light levels, lighting schedules, and more.
  • Carbon dioxide concentration monitoring for air quality and ventilation purposes and to estimate natural infiltration rates in buildings.
  • Pre-feasibility studies for proposed energy projects.

Ko Energy is an energy consulting company located in Yellowknife, NT, and operated by Dwayne Wohlgemuth. Ko Energy's expertise lie in energy auditing, energy management, energy modeling for buildings, performance monitoring, and utility benchmarking. Ko Energy has significant experience compiling energy statistics in the NWT including energy supply and consumption data, greenhouse gas emission inventories, and energy cost data. 

Ko Energy provides services during the months of October through April each year. Ko Energy is therefore not available during the months of May through September. Sorry for the inconvenience and thank you for your understanding!


North Slave Correctional Facility: In 2014, Ko Energy completed an energy audit on this facility in Yellowknife which includes three buildings all heated by a combination of wood pellets and heating oil. Data logging of carbon dioxide levels, lighting, and temperatures along with 8,760 hour annual modelling was used to determine the best energy management opportunities. 

Fort Smith Energy Audits: Ko Energy completed energy audits on three buildings in the Town including PWK High School, Breynat Hall residence, and the Northern Lights Special Care Home. These buildings all have new heat sources: electric boilers at the Northern Lights building and at Breynat Hall, and a pellet boiler at PWK. Carbon dioxide levels in the indoor air were tested to determine ventilation rates per person and whether demand control ventilation would produce significant savings.

City of Yellowknife Liquid and Organic Wastes: Ko Energy partnered with PlanET Biogas from Ontario to provide expertise on various ways that sewage, organic waste, and used vegetable oil could be used within the City of Yellowknife to produce valuable products, generate usable heat and electricity, and reduce land-filled waste.

Commercial Energy Conservation and Efficiency Program: Ko Energy is assisting the Arctic Energy Alliance with audits for NWT businesses through a program that provides energy audits and partial funding for projects to reduce energy consumption. Ko Energy has assisted with audits in Inuvik, Norman Wells, Tsiigehtchic, Fort Good Hope, Fort Providence, Fort Simpson, Whati, and Yellowknife. More information on the program is available here.

Inuvik Energy Options: Ko Energy produced a summary report of energy supply options for the Town following the depletion of the natural gas reserve at the Ikhil well. 

Fort Simpson Energy Audits: Ko Energy completed energy audits on three buildings including Bompas School, Thomas Simpson School, and the Milton Building. The audits include data logging, EE4 computer energy models, and normalization of fuel consumption at the Central Heating Plant which supplies steam to the schools. The Central Heating Plant is shown in the photo to the right.

Fort Simpson Solar Photovoltaic (PV) Project: Ko Energy completed a feasibility study for a solar PV project in the community. The project was approved, and construction began in November 2011. The 258 panel, 60.6 kW system is located at the Fort Simpson airport and was completed in February 2012. Data from the system is available online.

Energy Audit, Holy Trinity Anglican Church:
Ko Energy completed an energy audit for this Church as well as the adjacent rectory, the home of the Reverend. The final report for the Church is accessible online as an example of Ko Energy's work.

Used Vegetable Oil: Ko Energy worked with Ecology North to analyze options for using approximately 80,000 litres of used vegetable oil produced in Yellowknife each year. The oil is currently landfilled, but could be used for space heating or producing biodiesel.
