Heat pumps work like refrigerators — they transfer heat from a cold space to a hot one. Ball State’s heat pump system uses underground pipes to heat and cool 47 buildings, saving $2 million annually.
The building sector worldwide uses approximately 32 percent of all energy generated; more than one-third of that is for heating and cooling…
When paired with renewable energy sources and building structures designed for efficiency, heat pumps could eliminate almost all emissions from heating and cooling.
