Project Profile: Terra Caelo, St. George, Utah



What do you do when homeowners demand an HVAC system with the ability to control the temperature of individual rooms both in the house and remotely? What if that system also has to handle the extreme temperature swings of a climate like southwestern Utah while being extremely energy-efficient? And, what if the system has to be installed in a low-lying structure with no attic space and limited ceiling area for ducts?

When specifying the HVAC system for the Terra Caelo residence in Utah’s eco-conscious Kayeneta community, St. George-based J2 Construction and Ace Mechanical were presented with these exact challenges. They knew a Mitsubishi Electric system would be perfect for the unique needs of this job and installed an S-Series system that could be controlled remotely through a meZO Controller app. Despite space limitations, they were able to install most of the units in small closets with an access door. The result was a system that met the homeowners’ demands for complete comfort control from anywhere and was extremely efficient, resulting in the home using about 58 percent less kWh in energy each year than the average Utah home.

Homeowner Patrick Fox told us:

“Our goal was to have full control so that anyone in any room can choose the temperature they want, and to be able to shut off areas such as the guest rooms when they aren’t being used. Our house in California is all ducted and takes a substantial amount of money and energy to heat and cool. The mini-split systems aren’t pushing air around the house but using it in its location; no energy is lost. I can launch the [meZO Controller] app on my phone and monitor the temperatures remotely, and if guests have just left, I can adjust the temperature or shut off a unit from anywhere in the world.”
