Our Building

We invite you to  visit us! Our building is equipped with solar panels and a geothermal heating & cooling system. Read below to find out how they work, or join us for a renewable energy tour at KGMB. 

Solar Panels 


How they work:
Photovoltaic energy is the conversion of sunlight into electricity. Solar panels are a series of photovoltaic (photo meaning light, voltaic meaning electricity) cells (PVCs for short) arrayed so that they absorb the sun’s energy. Sunlight is composed of photons, or particles of solar energy. When photons hit the PVC panels, the energy is absorbed by semiconductors. When enough sunlight (energy) is absorbed by the semiconductor, excited electrons are dislodged from the material's atoms. The PVCs direct these electrons to flow in a path, generating electricity. The electricity collected by the solar panels on the Keep Greater Milwaukee Beautiful building is sold back to We Energies for a profit (cost savings). KGMB is equipped with SHARP panels (57 panels - each with 175 watt DC rating modules for a total of 10 Kilowatts).

Benefits of Solar Panels:

  • Save money on electric bill.
  • "Net metering" allows electricity to be sold back to the electric company for profit
  • Produce no air of water pollution.
  • Do not contribute to global warming.
  • They're completely renewable.
  • They will continue to supply energy even during power outages.
  • They reduce dependence on foreign oil.
  • They are nearly maintenance-free after being installed.
  • They are completely silent and have no moving part.
  • More panels can be added to any system.

Geothermal Heating (and Cooling)

How it Works:
Geothermal energy is heat from within the earth. While temperatures above ground change from day to day and season to season, temperatures in the upper 10 feet of the Earth's surface hold nearly constant between 50 and 60 degrees Fahrenheit. Geothermal heat pumps use stable ground or water temperatures near the earth's surface to control building temperatures above ground. Long pipes filled with water are buried underground 50-270 feet deep. The water is circulated through the pipes to keep it at the same temperature as the ground. This water is then used to heat or cool air, which is then circulated through the building through ducts, exactly the same as a regular heating system or air conditioning system, except for the source of the temperature of the air. The Keep Greater Milwaukee Beautiful building’s geothermal system is comprised of 4 heat pumps and a TRANE Heating and Cooling System.


Benefits of Geothermal:

  • It can save you 40-70% in heating costs in the winter and 30-50% in cooling costs in the summer.
  • It does not require the burning of fuel to create heat.
  • It does not contribute to global warming.
  • It reduces dependence on foreign sources of fuel.
  • It's Ccmpletely renewable.
  • According to the U.S. Environmental Protection Agency (EPA), geothermal heat pumps are the most energy-efficient, environmentally clean, and cost-effective systems for temperature control.
