The building consortium, which included Humphreys, investor group General Aviation LLC, Springfield, and general contractor, Atlas Building, Springfield, initially considered an in-floor radiant system. The price tag of more than $100,000 for this equipment and installation, however, deterred the consortium, and sent its members looking for a more economical system.
Humphreys said many hangars use space heaters, but he excluded this technology from being a serious option based on his past experience.
