The Messana Team went on a mission to start-up the radiant cooling system of the world’s first fully sustainable campus in higher education: Eden Hall Campus located in the North Hill of Pittsburgh in Pennsylvania.

Messana Radiant Cooling panels were installed in the new  Eden Hall campus (South Building Dormitory).  The three floor building has two wings (East and West) and about 90 rooms.

In the picture the taper is applying the “half moon circle” (drywall circular patches) that cover the connection windows of two adjacent Ray Magic panels.

 

 

The Messana Team (Maurizio Donadon, Greg Cross and Alessandro Arnulfo) worked for seven consecutive days to complete the wiring of the control panels (one panel per each floor plus one panel in the mechanical room located in the basement) and start up the radiant ceiling system for the first time.

Chatham Mix-Pump Station wiringThe team operated with the remote assistance from Italy of Andrea Ferrarelli and Federico Michilini who spent over four nights programming the system and completely testing in all its functionality.

Each panel controls 12 different mix-pump stations (4 for each floor, 2 per wing of the building). At the mix-pump station the thermal fluid temperature is modulated by the mixing valve and is sent to the manifold. Each loop of the manifold is equipped with a thermal actuator for zoning different student rooms and common areas (96 in total).

In the picture on the side there are some digital and infrared views of the Ray Magic radiant gypsum panels of the first floor building installed in the hall and a typical student room.  Panels are tested in cooling mode with supply water temperature of about 50F (purple color).

The radiant cooling system was started during the weekend of July the 4th (2015) when the building was completely empty. The first tour of the building with the infrared camera is always very exciting… you can clearly see all the radiant panels and how the radiant fluid flows.

As soon as the radiant cooling system is started you can immediately feel the cooling effect of the radiant ceiling.

    Interesting stuff.. I didn’t know we are doing this kind of building in the US. Is this really going to work?
    I’m always been intrigued by this radiant cooling system but never had a chance to try one.
    What kind of performance is expected for this system? How do you deal with the condensation?

      We have an advanced control system (Control Magic) with Temp and Humidity sensors. One per room and common area. In simple words: the control system estimates the radiant panel surface temperature and by modulating a mixing valve adjust the temperature of the supply water to maintain the radiant panel surface temp 1-2F above dew-point.

    We have many of these radiant cooling systems here in the US as well. I’m aware of many installation in the Bay Area CA but I think they are in the floor. This is the first time I see one in the ceiling. I would be interested in talking with the mechanical contractor that installed this system if it is possible. Thanks

      The mechanical contractor is Tudy Mecchanical (www.tudi.com).
      I’d be happy to discuss the details of this project with you. 855.RAY-MAGIC and ask for Alessandro
