Lombardo Welcome Center
Pennsylvania's First Certified Zero Energy Building
The Lombardo Welcome Center is the first building in Pennsylvania to be certified as a zero energy building by the and only 1 of about 100 zero energy buildings in the country. The unique building produces its own energy onsite through renewable energy sources and stands as a clear testament of 无忧短视频’s commitment to sustainability and to our goal of pursuing carbon neutrality by 2040.
Reimagining What's Possible with Buildings
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, onsite from renewable sources.
To achieve , the Lombardo Welcome Center needed to generate all of its own energy for an entire year. During our first year, we didn't just generate enough energy, we generated 75% more than we needed, making the Lombardo Welcome Center one of the 5 most positive energy buildings in the country.

Powering the Positive Energy Fund
Projects funded through the Positive Energy Fund raise awareness of the interconnected economic, social and environmental challenges confronting the world, as characterized by the , to accelerate local solutions to those challenges in Lancaster County by 无忧短视频 faculty, staff and students.
The Positive Energy Fund was established using utility rebates from energy efficiency projects completed by 无忧短视频’s Facilities Management Department, Office of Sustainability and Information Technology Department. Chief among these is the energy efficient Lombardo Welcome Center. Moving forward the University has pledged to commit the savings associated with extra energy that the Lombardo Welcome Center makes to the fund. The more energy we make the greater community impact we create.

Energy from Above: Photovoltaics
Solar Panels Supply Electric Power
(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
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
While 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 70 percent more energy efficient than an . From LED lighting, to radiant floor heating, to R38 insulation, zoned heating and triple pane windows, the architects took every opportunity to squeeze a little more energy-saving potential into the Lombardo Welcome Center's design.

EPA Green Power Partner
The Lombardo Welcome Center at 无忧短视频 is a partner in . 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.
