If you live in Alberta or BC, HVAC design must account for freezing winters and hot summers u2014 energy modelling helps optimise these systems for local climates. Electrical design should be integrated with HVAC and plumbing layouts to avoid installation clashes and ensure safety compliance. In high-rise buildings, plumbing engineers ensure proper pressure regulation and drainage efficiency across multiple floors.

How MEP Systems Work Together in a Commercial Building Mechanical (HVAC) System Controls indoor climate through heating, ventilation, and air conditioning. Ensures year-round comfort and air quality. Air Handling Units (AHUs): These help move air in and out of the building. Ductwork & Diffusers: Ducts carry air through the building, while diffusers spread it evenly into rooms. Chillers, Boilers & Heat Pumps: These provide heating or cooling, depending on the season. Exhaust & Ventilation Systems: These remove stale air and bring in fresh air to improve air quality. Electrical System Delivers power to the building and keeps systems running — from lighting and outlets to elevators and security systems. Power Distribution Panels: Supply electricity to HVAC units like chillers, air handling units, and exhaust fans. Lighting Layouts: Planned alongside HVAC systems to avoid clashes with ductwork and ceiling-mounted equipment. Emergency Backup Systems: Keep essential HVAC equipment running during power outages for safety and comfort. Fire Alarm & Communication Wiring: Connected with HVAC controls to shut down systems during emergencies and prevent the spread of smoke. Plumbing System Manages water supply, drainage, and waste removal — essential for hygiene and fire protection systems. Water Supply Lines These pipes deliver water to HVAC equipment like boilers and cooling towers, which are essential for heating and cooling. Drainage & Vent Systems Drain lines remove condensation from HVAC units, while vents balance air pressure and prevent blockages. Pump Rooms & Water Heaters Located in mechanical rooms, these systems support hot water generation for HVAC heating systems and other building needs. Backflow Prevention Devices Installed to protect clean water lines by stopping contaminated water from flowing back into the HVAC or plumbing systems. www.startechengineering.ca
