Optimized Ventilation for High-Performance Buildings
Overview ERVs and DOAS and how these specialized ventilation systems work in concert with VRF systems
Sponsored by Mitsubishi Electric Trane HVAC US LLC (METUS) | Presented by Kevin Miskewicz and Joe Cefaly
Webinar On-Demand
Evolving codes and standards, market-based incentives, sustainability concerns and a global movement toward better building design are driving the adoption of specialized mechanical ventilation systems. In this presentation, speakers Kevin Miskewicz and Joe Cefaly overview both Energy Recovery Ventilators (ERVs) and Dedicated Outdoor Air Systems (DOAS) and how these specialized ventilation systems work in concert with Variable Refrigerant Flow (VRF) systems to provide a complete high-performance HVAC solution.

LEARNING OBJECTIVES
- Identify current industry trends driving the adoption of specialized ventilation systems, as well as relevant standards and codes, including ASHRAE 62.
- 1 and the International Mechanical Code (IMC).
- Describe the similarities and differences between ERVs and DOAS in terms of function, impact on cooling and heating loads, and how each is applied with VRF systems.
- Discuss DOAS design options and requirements with consideration for decoupled DOAS, duct distribution networks, energy-efficiency measures such as demand-control ventilation, and refrigeration circuits engineered to provide cooling plus reheat.
- Explain how applications dictate appropriate ventilation solutions with consideration for building codes, climate, humidity, and how a space is used.
