Heat Pumps have been identified as the most readily deployable solution for both hot water, heating, and cooling applications. One particular heat pump technology, Air to Water, paired with modern hydronic distribution offers many advantages over standard Air to Air and Air to Refrigerant HP systems: including load shifting, efficiency scheduling, quiet operations, and micro-zoning. […]

This session will focus on simple dos and don’ts of duct design and register selection that can enhance both year-round comfort and energy efficiency. The session is NOT a deep dive into ACCA’s manual D and T, but instead focuses on practical solutions in new construction.

This class will focus on the proper sizing and installation of heat pump water heaters that will result in high levels of customer satisfaction and energy savings. Emphasis will be placed on minimizing noise and cold air complaints originating from the discharge air of the heat pump. This session will have a live display of […]

In this three-part session we will look at three major trend affecting Variable Capacity Heat Pump Systems around the world. Cold climate heat pumps have come a long way in the last ten years. We will look at NEEP cold climate heat pump list and the essential issues for good cold climate heat pump design. […]

Duct design is often a challenge for many builders and HVAC contractors. In this session we will look at best practices for duct design in residential new construction projects. Good HVAC ductwork is important for comfort, energy efficiency, and indoor air quality.

This session is designed to empower contractors with the knowledge and skills necessary to confidently integrate Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) into their projects. Aimed at both newcomers to ERV and HRV systems and those seeking to refine their design, installation, and commissioning processes.

Designing and installing HVAC systems to match the characteristics of a home is a much-neglected requirement of building codes and above-code programs. Ideally the heating and cooling load calculation is complete before construction begins. System selection should consider both first-cost concerns and long-term operational costs. Once the design is complete and the system selected, it […]

“Build tight, ventilate right” is a building science rubric that describes the approach of combining airtight envelopes, whole-house mechanical ventilation (WHMV), and effective and quiet kitchen and bathroom exhaust to achieve energy efficiency while promoting good indoor air quality (IAQ). This session will present findings from the U.S. Department of Energy Building America research study […]
