The Utilihab building system supports conventional heating and cooling systems but favors the use of more sophisticated energy-efficient technologies that can take advantage of modular component systems. Most conventional heating and cooling system hardware is accommodated by routing though the above-ceiling and below-floor volumes, using duct registers in floor and ceiling panels, and employing Supercabinet utility spaces. Due to large duct sizes common to conventional centralized HVAC systems, this may be limited to pitched roof structure designs affording much greater above-ceiling volumes. With the more sophisticated systems, however, better integration of components into the Utilihab panel and frame components becomes possible allowing for much more compact and energy-efficient systems better suited to the DIY builder.
Utilihab also favors the use of solar power for domestic heating and cooling and tends to favor the more active systems forms for that. Passive solar can be implemented with Utilihab, but its lighter high-performance structural systems lack thermal mass and this approach becomes suited better to Utilihab Pavilion System structures employing slab foundations. Active solar energy systems better compliment the Utilhab ideal of free architectural evolution as systems are less dependent upon the orientation and form of a structures relative to its solar insolation.
In this section we will explore the preferred heating and cooling systems used with Utilihab.
