HVAC

7:00–8:15
Asbestos—Yes, It's Still Out There.
Bob Rogalla, Lake States Environmental, Ltd
Harborside 204/205

The Minnesota Department of Health is actively developing an update to rules that will either already be in effect or published with an effective date in the not-too-distant future. Also, there are federal developments that may bring about a ban on many or even all asbestos, if passed. These developments will significantly affect the residential and commercial construction industries. Using our “bedroom” cut-away training prop and accompanying demonstrations, we will explore different materials and locations where asbestos can be found and how these situations should be handled.

8:30–10:00
What You Need to Know About Residential Furnaces, Air Conditioners and Heat Pumps If You're NOT an HVAC Professional
Scott Pigg, Seventhwave
Harborside 204/205

This session is meant to help builders, remodelers and homeowners better understand the key choices among furnaces, air conditioners and air source heat pumps—and to get top performance out of this equipment. Did you know that more than 80 percent of central air conditioners are installed improperly and do not achieve their rated efficiency? We’ll cover what matters—and what doesn’t—for maximizing comfort and minimizing heating and cooling bills. Based on independent monitoring and testing of hundreds of systems in Minnesota and Wisconsin, this will be a lively and practical session using an interactive audience polling system. Test your knowledge and bring your questions!

10:30–12:00
Balanced Ventilation Strategies for Cold Climate Housing
Mike Wilson, Dakota Supply Group
Harborside 204/205

This session will explore balanced ventilation systems from an installation, service and operation perspective. Options on sizing and duct design will be part of the session along with pros and cons of the duct/system design with and without a furnace system. Find out if the systems you are installing in your homes are meeting the 2015 Minnesota Energy Code. Learn about control strategies that are simple and functional and the difference between a HRV/ERV systems.

1:00–2:30
Slab on Grade Construction—Meeting the MN Energy Code Shell and HVAC Requirements
Mike Wilson, Dakota Supply Group
Harborside 204/205

This session is divided into two sections—building shell and HVAC. The presenter will focus on ways to meet the new 2015 Energy Code. Building Shell: Why is it more difficult for a slab on grade structure to pass the house tightness test than one with a basement? Learn about air sealing details that will help you achieve a tighter house. Common areas that are overlooked when it comes to air sealing will be talked about. Blower door results will be discussed. HVAC: Learn about different HVAC options, and how these designs might affect passing the house tightness and duct tightness test for your house. Techniques on duct sealing and meeting air leakage requirements if your ductwork is in the attic and balance ventilation will be discussed.

3:00–4:30
Keeping Ground Source Heat Pumps (GSHP) Systems on the Table
Ed Lohrenz, GEOptimize Inc.
Harborside 204/205

Building owners upgrading or selecting an HVAC system for their project are concerned about energy efficiency and the environment. GSHP systems are often considered early but are discarded by design teams because “they are too expensive” or “don’t work here.” Optimizing the design of a GSHP system is different than designing a conventional system. This presentation discusses two projects and how this efficient and reliable renewable energy option was “kept on the table” in Minnesota rather than being discarded without serious consideration.

Ed Lohrenz

Ed has worked in the many facets of the ground source heat pump (GSHP) industry for 35 years. Since 2006 he has worked as designer of larger scale commercial systems in Canada, the U.S. and internationally. He is the author of the Certified GeoExchange Designer course used by International Ground Source Heat Pump Association (IGSHPA). He has developed GSHP systems that integrate thermal energy storage to reduce peak energy loads to and from the ground and take advantage of off peak electric rates. He has authored numerous presentations and papers for ASHRAE and IGSHPA. His focus is the optimization of GSHP systems that reduce construction cost, improve efficiency and ensure long term operational sustainability.
