ABOUT THE COURSE
In this professional development training, the instructor guides attendees through the most common multifamily systems for HVAC, lighting, controls, building envelope and other common residential building systems. The course is design to provide an overview of residential / multifamily building components and go through the easiest ways to optimize those systems. The topics covered are practical and benefit those that operate and manage buildings and are looking for ways to reduce costs, improve operations, prolong equipment life cycle, and to help engage occupants on ways they can make the built environment function at optimum levels.
Who Should Attend - building operators, building owners, property managers, maintenance team, residential energy auditors and energy managers, residential energy facility contractors, etc. Intermediate level with attendees possessing a working of residential building systems.
Learning Objectives:
- Understand the main ways in which a building uses energy, how various systems operate and low-cost ways to optimize them.
- Explain the basic systems that make a site function.
- Discuss at a high-level what energy users need when it comes to energy management at the facility / operational / maintenance level.
Outline:
1. HVAC System Types in Multifamily
- Overview of packaged RTUs, split systems, PTACs/VTACs, boilers, and central chilled/hot-water plants.
- Where each is typically used (garden-style vs high-rise vs luxury).
2. Air Distribution and Ventilation
- Centralized vs unit-level ventilation strategies.
- Importance of outside air control and economizer logic.
- Link between infiltration, tenant comfort, and energy loss.
3. Controls and Thermostat Management
- Role of EMS/BAS vs stand-alone thermostats.
- Scheduling, setbacks, and deadband adjustments.
- Common pitfalls (over-tight setpoints, disabled schedules).
4. Central Plant Optimization
- Boiler staging and condensing boiler efficiency (return water temperature).
- Chiller part-load efficiency, condenser water reset, and pump VFD use.
- Proper sequencing and avoiding “competitive heating and cooling.”
5. Domestic Hot Water (DHW) Systems
- Storage vs instantaneous heaters, central vs in-unit systems.
- Recirculation loop control and insulation.
- Tenant comfort vs energy waste tradeoffs.
6. Lighting Systems
- Common multifamily lighting (corridors, garages, site lighting).
- LED retrofits and controls (occupancy, daylight).
- Importance of fixture maintenance and sensor calibration.
7. Plug and Common-Area Loads
- Elevators, laundry, fitness equipment, office spaces.
- Standby loads and phantom power.
- Contractor awareness of cumulative small loads.
8. Building Envelope and Infiltration
- Window performance, common air leakage paths.
- Pressure relationships in multifamily (stack effect, corridor pressurization).
- Value of blower door and duct leakage tests.
9. Maintenance Practices
- Coil cleaning, filter management, refrigerant charge, and economizer damper checks.
- Seasonal equipment inspections.
- Operator vigilance as a low-cost energy measure.
10. Tenant Engagement and Behavior
- Thermostat settings, space heaters, window ACs, and lighting usage.
- Education and incentives to align tenant behavior with building goals.
- Clear communication between management and occupants
