Commercial Ventilation Maintenance in Toronto

Toronto Commercial Ventilation Systems

Your Commercial Space’s Envelope

A building’s ‘envelope’ refers to the internal space contained by the building’s structure, the external walls, windows, roof, and floor. To have consistently comfortable conditions, you need to understand your building’s envelope and how it is sealed. The envelope is your barrier between your interior space and the outdoor environment. Knowing your envelope means being completely aware of your heating, commercial ventilation, and the insulation of your conditioned spaces.

A tight envelope means the more effectively your building contains its conditioned air—heated and air-conditioned air—within the building. Minimizing your building’s gaps and leaks helps to ensure a tighter envelope. Having a tight envelop reduces the load or strain—the ‘heat-load’—placed on your entire HVAC system and thereby increases your building’s operational efficiency—which in turn saves you money. Similarly, insulation helps slow heat-conduction through the walls and roof. Ensuring that your heating system is not overworking, extends its life.

Energy Efficiency

Promoting energy efficiency through regularly scheduled preventative maintenance doesn’t just save you money, it results in less energy used, of course, and promotes human health and comfort, and protects your building from subsidiary damage. As air circulates throughout your commercial space, it potentially removes pollutants—odors, gases, particulate, and moisture, as necessary. Improper ventilation contributes to drafty walls and uncomfortable indoor temperatures and humidity levels. Proper ventilation and air-distribution provide a safe, comfortable, and durable workplace.

Commercial Ventilation and Workplace Indoor Air Quality

The air in your commercial space may be circulating, but it still may be stale air, or worse. It is crucial to measure your commercial building’s Indoor Air Quality (IAQ). At Intelligent Comfort Solutions, we are not just concerned with your clients’ and tenants’ comfort, we’re concerned for their health.

Monitoring IAQ, and investigating the causes of poor IAQ is an integral component of our preventative maintenance strategy.

The Environmental Protection Agency (EPA) reports that many commercial buildings have “long-term problems” with Indoor Air Quality, and that “frequently” these “problems result when a building is operated or maintained in a manner that is inconsistent with its original design or prescribed operating procedures.” Consistent and methodical maintenance is the solution to counteracting poor Indoor Air Quality conditions

Analyzing and Diagnosing Indoor Air Quality

Intelligent Comfort Solutions analyzes and diagnoses commercial spaces to ensure that a building’s commercial ventilation system is operating at maximum efficiency and in accordance with the appropriate Canadian Standards Association (CSA) codes: the performance-testing standard for air-source heat-pumps CSA C273.3-M1991 and performance-standards for ventilation, CSA C273.5-1980.

Additionally, Intelligent Comfort Solutions ensures that the appropriate commercial ventilation equipment is running at high operational levels to save you money and protect your employees and tenants. Intelligent Comfort Solutions further ensures that ventilation systems effectively distribute clean, particulate-free air to all people in your commercial space.

Increasing ventilation rates and air-distribution is a cost-effective means of reducing indoor-pollutant levels. Ventilation systems should be designed to meet the minimum ventilation standards of local building codes. However, many systems are not operated or maintained to ensure that these design ventilation rates are provided.

Fundamentals of Good IAQ

Exceptional Indoor Air Quality is no accident. It results from a combination of factors: contaminant-source control, proper commercial ventilation, humidity management, and adequate filtration. All of these ventilation-health factors are an end-result of a dedicated preventative maintenance and operation schedule.

Commercial buildings are complex environments operating with many different operational zones, but all spaces rely upon the same air for basic functionality. Local exhaust-ventilation is essential for removing pollutants that accumulate in specific areas such as rest-rooms, copy-rooms, and printing facilities.

Ensuring that the operation of your air-handling systems, which control and regulate air-flow, for the supply of everyday air-quality are operating properly will result in a high degree of Indoor Air Quality. Commercial-industrial spaces require focused dust-extraction systems to regulate and maintain a fundamentally sound Indoor Air Quality.

Your  facility’s air quality condition depends on the quality and condition of your commercial ventilation equipment. Intelligent Comfort Solutions protects your facility’s air quality by scheduling routine tests for airborne contaminants, carbon dioxide, and other off-gases and vapours; as well as for microbial contamination, such as moulds and bacteria, from drain-pans, for example. Moulds, spores, and bacteria can be prevented from the simple installation of non-corrosive, sloping drain-pans—something that many of our clients fail to observe. Intelligent Comfort Solutions is your first line of defense against poor air-quality conditions.

Long-Term Energy Savings

In addition to maintenance, Intelligent Comfort Solutions provides advice and service for long-term energy savings through such initiatives as installing Variable Frequency Drives for air-handling units for buildings with intermittent occupancy, which permit for time-managed air-delivery for peak hours of occupancy, while idling during non-peak hours.

These control systems deliver continued comfort when necessary, energy efficiency, and consistent savings over the long-term. The savings in energy efficiency and reduced use combines to pay for the system in as short a period as three years, depending on the size, scope, and particular needs of your commercial space.

Other comfort solutions include the installation of a Heat Recovery Ventilator (HRV), which consists of two separate air-handling systems—one collects and exhausts stale indoor air, while the other draws in outdoor air and distributes it throughout the commercial space. HRVs provide fresh air at a reduced cost, while also saving energy by reducing heating and cooling requirements. Energy Recovery Ventilators (ERVs) work similarly except that ERVs also transfer humidity (or moisture) from the exhaust air to the intake air.
