Energy Efficiency and Green Buildings Questions

Multiple choice

What is the term used to describe the process of shifting energy consumption from peak to off-peak demand periods?

  1. Load shifting

  2. Peak shaving

  3. Demand response

  4. Energy efficiency
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Load shifting is the process of shifting energy consumption from peak to off-peak demand periods. This can be achieved through various strategies, such as using programmable thermostats to pre-cool buildings before peak demand periods or using energy storage systems to store energy during off-peak periods and discharge it during peak demand periods.

Multiple choice

Which of the following is NOT a common technology used in Demand Response programs?

  1. Smart meters

  2. Programmable thermostats

  3. Energy storage systems

  4. Electric vehicles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Electric vehicles are not typically used in Demand Response programs because they are not directly controllable by the utility company. However, electric vehicles can be used to provide grid services through vehicle-to-grid (V2G) technology, which allows electric vehicles to store energy and discharge it back to the grid when needed.

Multiple choice

What is the term used to describe the process of reducing energy consumption during peak demand periods without compromising comfort or productivity?

  1. Energy efficiency

  2. Demand response

  3. Peak shaving

  4. Load shifting
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Peak shaving is the process of reducing energy consumption during peak demand periods without compromising comfort or productivity. This can be achieved through various strategies, such as using programmable thermostats to pre-cool buildings before peak demand periods or using energy storage systems to store energy during off-peak periods and discharge it during peak demand periods.

Multiple choice

Which of the following is NOT a potential benefit of Demand Response programs for customers?

  1. Reduced energy costs

  2. Improved comfort and convenience

  3. Increased energy consumption

  4. Reduced greenhouse gas emissions
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Demand Response programs are designed to reduce energy consumption during peak demand periods, not increase it. Therefore, increased energy consumption is not a potential benefit of DR programs for customers.
