Lombardo Welcome Center

Millersville's First Zero Energy Building

The Lombardo Welcome Center is designed to be Millersville's first Zero Energy Building. Now open, the building stands as a clear testament of Millersville’s commitment to sustainability and to the goal of pursuing carbon neutrality by 2040. 

Achieving Zero Energy Certification

Buildings use energy to power lights, provide heat and air conditioning, and to run appliances, computers, and other devices. Typically, buildings pull most of that energy from the electricity grid, but zero energy buildings, like the Lombardo Welcome Center, generate their own energy from renewable sources.

To achieve certification, the building must generate all of its own energy for an entire year. We're tracking our progress in an online dashboard, tracking energy production and use every minute of every day. Click here to check out the dashboard!

Green Power Partner

greenpowerpartner

The Lombardo Welcome Center at Millersville University is a partner in EPA's Green Power Partnership. Established in 2001, the Green Power Partnership seeks to protect human health and the environment by increasing organizations' voluntary green power use to advance the American market for green power and the development of those renewable electricity sources. By generating all of its own energy and sharing the technologies with our students and the community the Lombardo Welcome Center aligns directly with the values and intent of this partnership.

  • Energy from Above: Photovoltaics
    Solar Panels Supply Electric Power

    Photovoltaic (PV) panels convert the sun's energy directly into electricity using semiconductor materials. The Lombardo Welcome Center has three types of PV panels, roof-mount, ground-mount, and solar glass.  The largest of these is a roof-mount PV array covering the majority of the Lombardo Welcome Center's roof.  In total, the roof array should generate about 175,000 kWh of electricity annually.  That should meet all of the building's electricity needs, but as an educational building, the Lombardo Center also provides an opportunity to demonstrate other technologies.  That includes a ground mount array located behind the building, allowing students and visitors to get a close look at the technology.  The ground-mount array has a dual-axis tracker that allows it to follow the sun over the course of the day. The ground-mount array should generate about 11,000 kWh of electricity annually.  Finally, the Lombardo Center has solar glass along the exterior, south-facing wall. The solar glass should generate about 8,000 kWh of electricity annually.  The ground mount array and solar glass provide a broader understanding of available technologies while producing additional electricity in case the building needs it or perhaps even making it a net positive energy building that can share electricity with other campus buildings.

  • Energy from Below: Geothermal
    Geothermal Heat Pumps Provide Heating and Cooling
    GeoWell

    Geothermal heat pumps use a physical property of the earth to their advantage. While Pennsylvania outside air temperatures can swing from below 0 to over 100 degrees Fahrenheit over the course of the year, the temperature just a few feet underground stays a relatively constant 54 degrees.  That means that in the summer the ground is cooler than the air and during the winter the ground is probably warmer than the air. A geothermal heating system takes advantage of this by running pipes filled with an antifreeze solution through the ground to pick up heat from the relatively warmer ground during the cold winter months or dump heat from the relatively cooler ground during the hot summer months. This heat exchange between the ground and the building means that the building's heat pump needs to do less work (consume less energy) to bring the outside air to a comfortable indoor temperature.

    The Lombardo Welcome Center has a vertical loop geothermal heat system that consists of 20 wells located underground in the rear of the building. The above image shows pipe being run through one of the 20 wells. 

  • Energy Efficiency
    Zero Energy starts with saving energy
     
    lombardo_eeWhile PV and geothermal systems get a lot of attention, the real workhorse of many zero energy buildings is energy efficiency.  The Lombardo Welcome Center, for example, is expected to be about 60 percent more energy efficient than the average building on Millersville's campus. From LED lighting, to radiant floor heating, to R38 insulation and triple pane windows, the architects took every opportunity to squeeze a little more energy-saving potential into the Lombardo Center's design.
