Energy

Question 1

Biomass energy

Answer 1

uses organic material which is burned to create energy. Biomass is renewable organic matter such as wood or ethanol (derived almost exclusively from corn).

Question 2

Passive Solar Design

Answer 2

mitigates the building’s energy needs. The goal of passive design is to maximize the amount of direct sunlight available to each building - for example, orienting streets and front lot lines along the east-west axis. In colder climates, windows facing south can capture solar energy for daytime heating.

Question 3

Solar photovoltaic (PV) systems

Answer 3

se photovoltaic cell technology to capture radiant energy from the sun and create electricity. Photovoltaic cells are placed on panels that are then placed on rooftops or mounted on the ground. Cells can operate at the residential to the utility scale.

Question 4

Energy Efficiency

Answer 4

Buildings are made more efficient by using insulation, which is rated in terms of thermal resistance, called R-value ( the resistance to heat flow). The higher the R-value, the greater the insulation.

Question 5

A minimum R-value recommended for residential use.
