Building systems. Energy-efficient technology
can result in great savings in the costs of lighting,
plumbing, heating, ventilation and air conditioning (HVAC), electrical and other major systems.
For example, incandescent light bulbs are being
replaced by more efficient compact fluorescent
bulbs and light-emitting diode (LED) lighting. Even
fluorescent lighting has improved greatly from T- 12
and T- 8 lighting to more efficient T- 5 lighting. Using
daylight whenever possible to light indoor spaces
capitalizes on “free” lighting. Installing lighting sensors and more energy-efficient lighting alternatives
can reduce energy use drastically.
Depending on the region of the country, the
HVAC system can be a prime target area for energy
savings. DOE said that about 56 percent of the
energy used in a typical home is for heating and
cooling. Here are some ways that heating and cooling costs can be reduced:
1. Geothermal systems use the earth to heat
and cool space within facilities at far less
cost than conventional systems.
2. Heat pumps often are far more energy-efficient than conventional systems.
3. Building automated systems provide monitoring and control mechanisms to ensure
that heating and air systems operate at top
Some building management systems are incorporating weather data and other historical information to adjust not only HVAC systems but all building systems. Total integration of building systems
is leading toward “high-performance” buildings.
Innovative technology is making new standards of
Operations and Maintenance. Even if an owner
installs the latest and greatest technology in a facility, poor operations and maintenance will mitigate
any savings over time. Simple things such as regularly changing air filters add life to equipment and
improve its efficiency. Preventive maintenance
plans pay for themselves by reducing the frequency of equipment replacement costs and bring-
