Lourdes University Classroom Addition

Lourdes University Classroom Addition includes classrooms, a computer lab, recreation area, and offices in over 43,000 square feet. The HVAC systems were designed to reduce energy consumption and to allow Lourdes University complete flexibility in scheduling the use of the building.

HVAC Systems Include:

– 39 Geothermal Heat Pumps with a minimum rating of 21 EER (energy efficiency ratio) to provide simultaneous heating and cooling for the building. Note that the system is located under the parking lot shown in the photo above.

– Three (3) Energy Recovery Units to transfer a percentage of the exhaust sensible and latent energy to the incoming ventilation air. The total thermal efficiency averages 70% in the heating season and 60% in the cooling season.

– The pumping system consists of one (1) 310 gpm pump (with 100% back-up) which distributes the glycol solution from the well field to the heat pumps throughout the building. The well field consists of 48 holes, each 300 feet in depth.

– A DDC control system controls all space temperatures and HVAC equipment operation.

Electrical Systems Include:

– The lighting system was designed with an eye toward energy efficiency while still maintaining user friendly controls for both staff and students.

– All of the offices, study rooms and restrooms contain either wall mounted or ceiling mounted motion sensors for control of the lighting.

– The study rooms and classrooms also contain standard wall switches to allow the occupants to adjust the light levels themselves according to the amount of light that is needed.

– All the lighting in the corridors and main computer lab are wired through motorized breakers that are controlled by a time clock contained within the lighting panel.

– Energy efficient electronic ballasts were utilized in all fixtures containing ballasts.

The total interior lighting loads equates to 1.1W/Sq. Ft. which is an 8% improvement.
