Fuel & Energy Sources

Introduction

Regardless of what energy conservation choices are made and sustainable strategies employed, it is still relatively rare for buildings to be Net Zero (requiring zero energy). Even if a building is able to achieve net zero, fluctuations in seasonal weather will typically mean a building needs to supplement its energy in some way. Typically this energy is supplemented through conventional fuel and/or storage.

Use and Movement

Every type of fuel needs to be converted into a useful form, such as heated air or chilled air, or heated water or cooled water. Once the fuel has been converted to a useful energy supply, the distribution of the energy usually requires an additional energy source to operate pumps and fans.

Selecting Type of Fuel

Fuel source selection depends largely on availability, but also the efficiencies and how much fuel will be needed should be taken into account. Another aspect is cost as different fuels have great fluctuations in price over geographical areas.

• For example, in urban areas, steam may be a byproduct of electricity generation, and may be readily available for purchase and hook-up. However, it is rare in suburban areas, and Oil or Natural gas may be the only fuels available which may require intermittent deliveries.

Natural Gas

The most efficient of all fossil fuels. It accounts for about 30% of the energy used in the United States.

• Cleanly burns & Fairly cheap
