How Science House Works

Science House is a 1,700-square-foot building located behind the museum.

Science House is not open to museum visitors. The building is home to the museum’s IDEAL Center, providing professional development services in Inclusion, Diversity, Equity, Access, and Leadership.

Science House is both a vibrant teaching space and an environmental experiment, because it is designed to operate as a zero-emissions building (ZEB). ZEBs produce all of their energy needs on an annual basis. Since energy monitoring began in February 2004, Science House actually has been producing more energy than it uses on an annual basis.

The energy monitoring of Science House is performed by The Weidt Group with equipment installed and provided by the U.S. Department of Energy’s National Renewable Energy Laboratory.

How Science House Works

Buildings account for about 35 percent of all energy consumption in the world. By bringing together energy efficiency and renewable energy technologies, Science House will test the idea that even in Minnesota’s climate, houses can be constructed to generate much, if not all, of their annual energy needs. Here is how Science House works:

  1. Science House’s solar photovoltaic standing-seam metal roof generates electricity from sunlight.
  2. The direct current (DC) electricity from the solar roof feeds into inverters on an outside wall of Science House that convert the DC into alternating current (AC).
  3. Electricity from the inverters powers the Science House, including a ground-source heat pump.
  4. The heat pump circulates a non-toxic fluid through plastic tubes looped down four, 250-feet-deep wells.
  5. The heat pump extracts heat from the Earth to warm Science House in winter.
  6. The heat pump extracts heat from Science House and dissipates it into the Earth to cool Science House in summer.
  7. Energy-efficient windows allow for passive solar heating in winter and minimize the need for artificial lighting year-round.
  8. Energy-efficient lighting and lighting controls minimize the use of electricity to light Science House.
  9. Spray-in foam insulation in the walls and ceiling creates a building envelope with a high R-value and minimal uncontrolled air infiltration.
  10. Science House feeds electricity back to the Science Museum when the solar roof is generating more than Science House is consuming.
  11. Science House draws electricity from the Science Museum when Science House is consuming more than the solar roof is generating.
  12. The goal is that Science House produces as much energy as it consumes on an annual basis.
