Effective and Efficient Design

Unique projects require unique solutions. TYZ is committed to exploring how different technologies can benefit a project to meet our client’s needs. Our mechanical systems conserve natural resources, reduce operational expenses and create a safe and healthy environment for a building's occupants.



The heating, ventilation and air conditioning (HVAC) systems are a corner stone for a healthy, safe, efficient, and comfortable indoor environment within a building. Our systems provide necessary heating, cooling and ventilation to maintain optimal thermal comfort for building occupants, while meeting code requirements and energy consumption targets. We provide HVAC design services for a variety of areas and systems including:

  • Base Building System Design
  • Modernizations and Renovations
  • Tenant Improvements
  • Variable Air Volume (VAV)
  • Heat Recovery
  • Variable Refrigerant Flow (VRF)
  • Low Temperature Heating Systems
  • Solar Heating Systems
  • Radiant Heating Systems
  • Heat Pumps
  • Free Cooling Chillers
  • Displacement Ventilation
  • Laboratory Ventilation and Exhaust
  • Health Care and Clinical Ventilation
  • Dust Collection
  • Smoke Control
  • Specialty Exhaust Systems

Plumbing and Drainage

These systems are essential to properly functioning buildings from commercial structures to complex industrial systems. We design and select piping, fixtures, appurtenances, and appliances related to water supply, sanitary, and storm drainage facilities for a complete plumbing system. Plumbing & drainage systems include:

  • Rain Harvesting
  • Sustainable Low Water Use Systems
  • Solar Water Heating
  • Medical Gas Systems
  • Laboratory Drainage
  • Waste Treatment (Separators, Neutralizers)

Fire Protection

Fire protection systems are a necessary service to ensure that the occupants and property remain safe and protected from loss. Every project will present unique challenges and environments from warehouses with high density racking, to data centres with critical operation requirements, to commercial office settings. With our experience and knowledge, the proper fire protection system will be specified to meet project specific needs. A variety of fire protection solutions may be applied such as:

  • Wet Pipe Sprinkler Systems
  • Dry Pipe Sprinkler Systems
  • Clean Agent / Dry Chemical Fire Suppression
  • Pre-Action Fire Sprinkler Systems
  • Deluge Fire Sprinkler Systems

Energy Management & Control Systems

Understanding the intricacies of overall mechanical system operation is key to applying proper energy management and control strategies. With design experience across a wide range of project types, mechanical systems and building markets, we develop these strategies and utilize the best suited controls technology to meet our client’s goals such as reducing energy usage and increasing thermal comfort. Strategies applied may include:

  • Wireless Controls
  • Energy Metering
  • Open Protocol Systems
  • Energy Analytics
  • Web Based Interfaces

Industrial ventilation

This includes a broad number of systems which control interior environments in varying ambient site conditions ranging from control of exposure to toxic airborne chemicals or flammable vapours to managing interior temperatures for sensitive electrical equipment. Our expertise lies in creating suitable spaces in industrial environments and in-depth knowledge of potential hazards and risk mitigation for many building types including:

  • Electrical Substations and Switchhouses
  • Switchgear Buildings
  • MCC Buildings
  • VFD Buildings
  • Control Buildings
  • Purge and Pressurization

Building Energy Analysis and Energy Modelling

With continued and expanding interest in energy-efficient building design, whole building energy simulation is increasingly being employed to help design teams and owners determine which design strategies save energy and are cost-effective. We have modeled all types of buildings and have applied energy models to such programs as:

  • LEED (Leadership in Energy and Environmental Design)
  • NECB (National Energy Code of Canada for Buildings)
  • BOMA Best (Building Owners and Managers Association)
  • Green Globes
  • ASHRAE Energy Assessments

Mechanical Commissioning

As a result of construction methods and mechanical systems becoming more complex, commissioning has become a critical service ensuring a better performing building. Whether the commissioning is performed during the construction stage of a newly built building, or if completed on an existing building, the benefits remain the same:

  • Improved Comfort and Building Performance
  • Reduced Energy and Utility Costs
  • Lower Environmental Impact
  • Properly Trained Maintenance Team
  • Increased Project Value

Mechanical Building Assessment Studies

With finite resources available to operate buildings, facility management teams need a method to identify opportunities and strategies to be cost efficient. Mechanical building assessment studies is a powerful tool that management teams can utilize to improve their portfolio renewal forecasting and address capital funding for capital projects. Assessments review historical and current information on the facilities and provide evaluations on mechanical equipment and systems in terms of condition, code compliance issues and where energy saving opportunities may be available. We offer a number of assessment options such as:

  • Mechanical Condition Assessments
  • Feasibility Studies
  • Mechanical System Audits and Reports
