It wasn’t anything like the usual new home.
“Everything about the design was custom,” said Roger Kaminga, owner and president of Hendrix Heating of Corvallis. “Nothing was as it normally is on a new construction site.”
Kaminga was part of a collaboration of construction-related businesses recruited by BASF Center for Building Excellence that also included Palm Harbor Homes in Millersburg. Together they put together two BASF “BEYOND.High Performance” homes to show at the National Association of Home Builders International Builders’ Show held in Las Vegas in January.
The home, built to be at least 50 percent more energy efficient than a standard code-built home, was all about savings. It achieves a Home Energy Rating System (HERS) index score of 50 percent and reduces water use by 20 percent or more.
BASF selected Palm Harbor Homes and Hendrix Heating to participate in the construction of a manufactured home that would showcase products and building techniques that can be combined to create the desired energy efficiency.
One home was only partially built and set up to show the materials, equipment and methods used. The second was a finished home. Following the Las Vegas show the homes have been on display at other events around the country.
“It was a unique project,” Kaminga said of the homes that were started in December and on the road to Las Vegas for the show by Jan. 12.
The 945-square-foot homes were constructed by Palm Harbor at its plant in Millersburg.
BASF designed a specific HVAC system that Hendrix then adapted and installed in the homes.
“Our role was to develop it in such a way that the system would be permanent, portable and presentable,” Kaminga said. “It had to be a TRANE system developed in a way as to be connected, disconnected and then reconnected in multiple locations.”
Kaminga, installation manager Adam Strilka, Josh Szaroleta and Troy Deyoung worked on the project for Hendrix. The group was on the job in Millersburg for three days.
HVAC performance tests measured the efficiency of the system. According to Kaminga, the tests showed the BASF home outperformed standard code-built homes.
A powerful fan is mounted in the frame of an exterior door, and all other ‘intentional’ openings in the house like windows, exterior doors and fireplace dampers are closed. The fan sucks air out of the home, allowing pressurized air from outside to leak in through every gap, crack and hole in the building. That helps calibrate the HVAC system for optimum energy efficiency and air quality.
The system showed maximized energy efficiency, thermal comfort and indoor air quality all at the same time, Kaminga said.
