How to Manage and Reduce Your Tenants Heating Costs
27 July 2020

Did you know that 60 to 80% of the energy consumption of a multi-residential building are directly due to tenant’s space heating? While the price of electricity, as well as natural gas, rises every year, heating is one of the most important expenses for housing providers. In addition, tenant’s behaviour is a direct cause of energy waste: opened windows in the winter, overheating, etc. Seems familiar? Fortunately, some proven and reliable technologies are available to reduce your energy bills.

How to Generate Savings

Building and heating systems are designed for maintaining comfort on the coldest day of the year. Heating capacity remains the same year-round, even though only a fraction of the capacity is required to maintain comfort during these times. This results in having an overcapacity of heat which leads to losses in the case of negligence, bad habits, or even abuse by some tenants. This is especially apparent in multi-residential heating systems where the heating costs are paid by the building owner or property manager via a bulk meter for gas or electricity.

Installing a heating management system that manages in-suite heating consumption has been proven to be an efficient way to save energy and to reduce the environmental footprint. Without in-suite control technology, a thermostat has the authority to control the heating element 100% of the time (whether electric, hydronic…). With a heating control system, the operating time of the baseboards can be managed and reduced.

Fundamental Behind Heating Management

Heat management systems control the heating capacity of the building based on a combination of real time outside temperature, zones of the building, period-of-use, and temperature set point. Each apartment is controlled by a main computer which allows heating depending on the weather and its dedicated energy program. An algorithm interacting with in suite sensors calculates the amount of energy needed to heat the apartment. In a cold winter day, 100% heating is allowed, so tenants are comfortable. In the rest of the year, there’s always enough energy available to reach the desired in-suite temperature, but not to be wasted. In addition, a load shedding function controls the operation cycles of all the building’s heating equipment in order to reduce the peak demand, resulting savings in kW.
