Energy Management and Building Sustainability
Study
1
Question
What is the primary definition of energy management?
Answer
Proactive and systematic monitoring, control, and optimization of energy consumption to increase efficiency and decrease costs.
2
Question
How does energy management typically achieve reduced energy use?
Answer
Through elimination of waste and optimization of building systems.
3
Question
What are the core components of sustainability in the built environment?
Answer
Environmentally responsible and resource-efficient buildings and life-cycles, balancing economic growth, environmental care, and social well-being.
4
Question
In what phases is sustainability considered for buildings?
Answer
Design, construction, and operation/maintenance without sacrificing performance.
5
Question
What is a key focus of sustainable building design regarding resources?
Answer
Energy and water efficiency along with pollution reduction.
6
Question
What motivates sustainable building design in relation to climate change?
Answer
Minimize consequences of climate change, as buildings are significant greenhouse gas emitters.
7
Question
How do buildings contribute to global environmental challenges?
Answer
As major sources of greenhouse gas emissions.
8
Question
What is Scope 1 GHG emissions classification?
Answer
Direct emissions from sources owned or controlled by the organization, like on-site fossil fuel combustion.
9
Question
What does Scope 2 GHG emissions include?
Answer
Indirect emissions from purchased energy generation owned or controlled by the organization.
10
Question
Provide examples of Scope 3 GHG emissions sources.
Answer
Employee travel, commuting, manufacturing, and transportation of purchased goods.
11
Question
How do Scope 1 and Scope 2 emissions differ from Scope 3?
Answer
Scopes 1 and 2 are from owned/controlled sources; Scope 3 from related but uncontrolled activities.
12
Question
What influences the built environment's response to regulations?
Answer
Changing codes and standards, market expectations, and local/federal incentives.
13
Question
What is a primary strategy for energy management in existing buildings?
Answer
Reduce energy usage by eliminating waste and optimizing systems via Building Management System.
14
Question
How can existing buildings procure renewable energy?
Answer
Through solar, wind, or other renewable sources.
15
Question
What role does a Building Management System play in existing buildings?
Answer
Controls electrical and mechanical equipment to optimize energy use.
16
Question
What is a microgrid in energy management systems?
Answer
System that manages total electric demand, including EV charging controls.
17
Question
How do lighting controls contribute to energy management?
Answer
By incorporating daylighting to reduce energy consumption.
18
Question
What are examples of energy storage systems in buildings?
Answer
Batteries and thermal storage like ice.
19
Question
What growing emphasis exists in energy management for new construction?
Answer
Electrification of heating and cooling systems instead of fossil fuels.
20
Question
Why consider local factors in new construction energy procurement?
Answer
Local climate, standards, codes, goals, and grid carbon intensity vary across the US.
21
Question
What is the process of building electrification?
Answer
Replacing fossil fuel-based systems with all-electric alternatives.
22
Question
What are primary motivations for building electrification?
Answer
Improve efficiency, reduce costs and carbon emissions, enable clean grid integration, and comply with regulations.
23
Question
How does electrification satisfy regulatory requirements?
Answer
Through local gas bans like NYC Local Law 154 and New York's All-electric Buildings Act.
24
Question
What incentives support building electrification?
Answer
Rebates and tax credits from the US Inflation Reduction Act.
25
Question
What electric replacement is used for natural gas-fired boilers in heating?
Answer
Electric heat pump.
26
Question
How does electrification affect domestic hot water systems?
Answer
Replaces natural gas-fired water heaters with electric heat pump water heaters.
27
Question
What is an electric alternative for gas-fired cooking appliances?
Answer
Induction stove and electric oven.
28
Question
What does NYC Local Law 154 mandate for new buildings?
Answer
Phased restriction of natural gas use, requiring all-electric systems for buildings under 7 stories.
29
Question
What enforcement mechanism applies to NYC Local Law 154?
Answer
Fines, with exemptions for emergency backup generators.
30
Question
What are the steps in the path to electrification?
Answer
Utilize existing resources, load reduction, electrification, renewable resources, and optimization.
