Meline Engineering specializes in designing sustainable, energy-efficient mechanical systems for commercial, government, public and residential buildings. We have particular expertise in geothermal heat pump, solar thermal, evaporative cooling and energy recovery systems. Since 1995, we have designed geothermal and sustainable energy systems for more than 45 public buildings and 76 residences. Projects have included correctional facilities, office buildings, schools and large custom homes.

Recognized in our industry for leadership in geothermal technology, practices and standards, we are frequently asked to speak at conferences and events.Our team teaches thermodynamics at Sacramento State University and lectures on geothermal energy systems design at the University of California, Davis, Extension Program.

We believe in efficient, innovative design and strive to work on projects that incorporate our ideals. We work closely with other members of the design/build team (civil, electrical, architectural and specialty contractors) with open communication and coordination of documents.  More »

Geothermal heat pumps – energy-efficient heating and cooling using the constant temperature of the earth

A geothermal heat pump, also known as a ground source heat pump or Geoexchange, taps the energy stored in the earth to provide energy-efficient heating, cooling and hot water for buildings. The technology uses the constant temperature of the earth as the medium of heat exchange instead of outside air temperature. Less than 10 feet beneath the surface of the earth, the ground remains at a relatively constant temperature. In winter, this ground temperature is warmer than the air above it. In summer, the ground temperature is cooler than the air temperature.

Less than 10 feet beneath the surface of the earth, the ground remains at a relatively constant temperature. In winter, this ground temperature is warmer than the air above it. In summer, the ground temperature is cooler than the air above it. A geothermal heat pump takes advantage of this temperature difference by exchanging heat with the earth through a ground heat exchanger.  More »

Solar thermal – providing up to 65% of household hot water and 60% of heat for swimming pools

Solar heating harnesses the power of the sun to provide solar thermal energy for solar hot water and solar pool heating. A typical residential solar water-heating system reduces the need for conventional water heating by about two-thirds. It saves energy, reduces utility costs, and uses clean energy.  More »
