When building their new high-performance home in Ann Arbor, Michigan, Eric and Jo Ann faced the integral challenge of constructing a house that not only ensured energy efficiency but was able to do so in the region’s cold winter temperatures.
With the help of architect Michael Klement, AIA, NCARB, AIBD, CPHC from Architectural Resources, the homeowners selected a Mitsubishi Electric mini-split heat pump system for its versatility and scaled-down size.
Based on the region’s climate, their heating and cooling system selection was one of the most important features the homeowners needed to consider. Mitsubishi Electric’s Hyper-Heating INVERTER® (H2i®) technology presented the perfect solution to withstand the below-freezing temperatures while maintaining high-performance home standards for any season.
“Hyper-heating technology allows the unit to extract heat at lower temperatures than most units can go to,” said the installing contractor Andy Bobo, owner, CMR Mechanical. The team installed a mix of ducted and ductless equipment with 2 MSZ Wall-Mounted Indoor Units and 2 SEZ Horizontal-Ducted Indoor Units.
“The nice thing about Mitsubishi Electric is that people ask for it by name. They’re not just asking for a ductless unit specifically; they’re asking for a Mitsubishi Electric ductless unit,” Bobo added.
Since completion, the Ann Arbor Passive House has been officially verified by energy rater Building Efficiency Resources (BER).
“The home attained a HERS Index® score of 14, is ENERGY STAR® Certified, EPA Indoor airPLUS certified and is projected to meet DOE Zero Energy Ready Home and Passive House Institute US (PHIUS+) status,” said Chris McTaggart, co-owner, BER.
The project team also plans to add solar panels to the home in an effort to increase energy efficiency and offset total energy use.
“We are very, very pleased with how the house turned out,” said Eric. “This home is an opportunity to lead by example and it’s already exceeding our expectations.”
