The Richard J. Klarchek Information Commons, located on the Loyola University Chicago campus, was completed in December of 2007.  Solomon Cordwell Buenz designed the building to optimize energy efficiency while keeping the majority of the building transparent on the east and west facing sides. A key feature of the building is its concrete ceiling panels. These panels provide a three-in-one solution that is both sustainable and energy efficient. The panels are pre-fabricated to allow for ease of construction and reduced waste. The vaulted shape of each panel provides a greater surface area for the radiant heating and cooling tubing installed within. Additionally, each vault when used with upward lighting increases the distribution of light, reducing the overall strength (and therefore energy) needed to illuminate the building.

The most common radiant heating systems consist of two types: hydronic and electric. Hydronic radiant heating systems typically utilize a gas boiler to heat water and an electric pump to circulate heated water throughout the floor area.  Electric radiant heating uses electric heating elements within the floor. Electric systems are usually less expensive than a hydronic system to install and do not require the installation of a boiler. However, the overall efficiency for electric does not compare to a hydronic system  -generating heat from a power plant requires more energy than using heat directly from a liquid source.  Additionally, electric systems cannot be paired with a geothermal ground source loop. Electric systems are most efficient when used in a smaller space such as a bathroom or kitchen. (Wikipedia, Under-floor Heating) On average, a hydronic system can cost as little as $2/sq. ft. An index of radiant heating information, installation and pricing can be found at the Radiant Design Institute website. Diagrams, manuals and cad drawings can be found through Warmzone.
