FACT SHEET HANDOUT
Information about the Science
and Education Center at Black Rock Forest.
- The Footprint of a building is
the area of land the structure stands on. For the Black Rock Science and Education
Center (SEC), the footprint is approximately 22m x 13m or 286 sq meters. The
total useable interior floorspace of the building is 8881 sq feet, or 825
sq meters, spread across three floors.
- The long dimension of the building
is oriented on an east-west axis to take advantage of solar heat in winter,
and to protect against solar heat in summer.
- The windows are on the south
and north facades to reduce solar gain in summer, and increase solar gain
in winter, and to allow for cross-ventilation. Windows use high R-value glass
with high visibility, low shading coefficient, and have overhang and awnings
for shade on the south side.
- The SEC additionally has these
green building features: energy efficient lighting, light sensors, a good
thermal insulation envelope, efficient HVAC system using the GHP, good Indoor
Air Quality (IAQ) and rate of air exchange, non-toxic interior materials and
finishes; uses sustainably harvested wood and local stone; has composting
Information about Geothermal
Heat Pumps and Energy Use.
- The Geothermal Heat Pump (GHP)
at BRF is installed within five 500 ft bore holes in rock.
- The GHP at BRF accounts for approximately
one half of its total power demand.
- Space heating and air conditioning
account for 20% of energy used in the US.
- A Geothermal Heat Pump uses 45%
of the amount of fuel as a furnace, and can reduce consumption of heating
energy by 20-40%; and of cooling energy by 30-50%. In general, a GHP uses
< 1/2 the conventional energy to heat and cool SEC, according to Pachi
Fact about Energy Use
and Global Warming.
- About 99% of the energy used
to heat the earth and all its structures is derived directly from the Sun.
- Solar energy is converted into
renewable resources: biomass of trees and other plants by converting to chemical
energy through photosynthesis, and wind and water by converting to mechanical
- About 1% of the remaining energy
is generated primarily from non-renewable fossil fuels.
- According to the United Nations
International Panel on Climate Change (IPCC), July 2000, average global temperature
could warm by 5.8° C by 2100, twice the previously anticipated rate.
- The United States with about
4.6% of the worlds population uses 25% of the worlds commercial
energy, 85% of that from non-renewable fossil fuels.
- In the US, roughly 43% of commercial
energy used is wasted unnecessarily due energy inefficiency of poorly designed
- A modern power plant produces
electrical energy at the rate of about one billion watts or 1000 megawatts.
