The state’s environmental community strongly supports the switch to renewable energy.

New Jersey Governor Phil Murphy signed an executive order on February 15, 2023, committing the state to 100% clean energy by 2035. This commitment will position New Jersey as one of the first states in the country to fully transition to renewable energy sources. The Governor also presented six fundamental elements that will establish the basis for a more sustainable, eco- friendly, and stronger New Jersey, such as installing zero-carbon-emission heating and cooling systems in 400,000 homes and 20,000 commercial properties. According to the World Economic Forum, buildings account for nearly 40% of the world’s energy consumption and about one-third of the total greenhouse gas emissions. Much of that is due to inefficient heating and cooling systems. One study says nearly 10% of US emissions come from fossil fuel consumption from water heaters, furnaces, and other heating sources. As a compelling solution, the decarbonization heat pumps move heat between the air inside and outside a home to recover and repurpose heat, delivering up to three times more heat energy to a home than the electrical energy it consumes. The state’s environmental community strongly supports the switch to renewable energy. Doug O’Malley, director of Environment New Jersey, called the order “a necessary step toward reducing emissions from our buildings, the second-highest polluting sector in the state while delivering clean air and healthier homes.” Financial incentives have been provided at the federal and state levels to promote the transition. For example, households can receive a federal tax credit to cover up to 10% of the cost of insulation materials and other energy-efficient improvements, like energy-saving windows and doors, in 2022. They can also receive a $300 tax credit for purchasing efficient heating and cooling equipment, like a heat pump or central air conditioner. Low-income households in NJ would qualify for additional financial assistance to purchase and install them. In contrast, the opponents argue that New Jersey does not have the infrastructure to support such rapid and radical changes and are concerned with the installation cost – “Governor Murphy doesn’t care how many tens of thousands of dollars it will cost New Jersey families to convert their gas stoves, water heaters, and furnaces to fully electric appliances.” In addition to high installation costs, greater space and insulation requirements may further hinder the transition. Imagine that you are advising that decision-making body on their response to the heat pump (or other zero-carbon-emission heating and cooling solutions) adoption. Choose between organization (e.g., country, state or county governor, local business owner, homeowner association, etc.), company (HVAC manufacturer, hardware supplier, house builder, etc.), or household. Apply the techniques you have learned in this class to develop a recommendation and justify any assumptions you make. Your analysis and the report detailing the full context and analysis should include the following steps:   *0.Choose a decision-making body and research how heat pump adoption impacts them and their constituents/stakeholders. Briefly describe the decision-making body and its current situation, citing all sources and avoiding plagiarism (150-300 words). [10pts] *1. Identify the fundamental/ends and means objectives for that decision-making body. Construct objectives diagrams—either (a) a fundamental objectives hierarchy plus a means objectives network or (b) a hybrid diagram—to illustrate the relationships among the objectives. [15pts] *2. Identify alternatives. Be creative, and use existing proposals (citing your sources). Develop a consequence table with four mutually exclusive, non-dominated alternatives and four attributes (attributes should be consistent with objectives in Parts 1 & 2). At least three attributes should be represented as continuous variables on an interval or ratio scale (i.e., not nominal or ordinal attributes). [15pts] *3. Identify uncertainty in at least two attributes and present justified uncertainty distributions of those attributes for all alternatives. You may use objective data or (more likely) generate. your own subjective probability distributions (using techniques from Week 5) based on your interpretation of the situation. Explain your process and cite/justify any assumptions. [10pts] *4. Develop a multi-attribute utility model to evaluate your alternatives, using the appropriate methods we learned in class. You may assume an additive utility function, but you should use methods from Week 6 to find the univariate utility functions (CE, PE, or TO) and the weights (swing or lottery weights). [25pts] *5. Evaluate the utility model for each alternative from your consequence table, accounting for uncertainty (e.g., using a Monte Carlo simulation). Provide information about the utility distribution for each alternative (e.g., means, histograms). [10pts] *6. Perform sensitivity analyses over at least two factors to assess the robustness of the results and briefly explain the meaning of each of those analyses for decision-making. [10pts] *7. Make a clear recommendation based on the results and describe any limitations/caveats that the decision-making body should be aware of. [5pts] You may use any generally available research sources such as news articles and journal papers (cite your sources) but be aware that some websites and organizations are biased and may provide misinformation. -Submit a stand-alone pdf document detailing your analysis, including all necessary contextual information and explanations of your assessment and procedures. -You should also attach an Excel or code file as a supplement so I can check your calculations if needed. • Completeness of analysis • Consistency and clarity • Correct application of decision analysis tools • Justification of models and assumptions

Sample Solution

     

Part 0: Decision-Making Body and Impact of Heat Pump Adoption

Decision-Making Body: Homeowner Association (HOA)

Current Situation:

The HOA is responsible for maintaining the common areas of the community, including the landscaping, swimming pool, and clubhouse. The HOA also sets policies and regulations for the community, such as parking restrictions and noise ordinances.

The HOA is currently considering whether to switch to heat pumps for the community's heating and cooling needs. Heat pumps are a more efficient and environmentally friendly way to heat and cool buildings than traditional systems such as furnaces and air conditioners.

Full Answer Section

       

Impact of Heat Pump Adoption:

Switching to heat pumps would have a number of benefits for the HOA and its members. First, it would reduce the HOA's energy costs. Heat pumps are more efficient than traditional systems, so they would use less energy to heat and cool the community's buildings. This would save the HOA money on its utility bills.

Second, switching to heat pumps would reduce the HOA's carbon footprint. Heat pumps use electricity to operate, and electricity can be generated from renewable sources such as solar and wind power. This would help the HOA to reduce its greenhouse gas emissions and contribute to a more sustainable future.

Third, switching to heat pumps would improve the comfort of the community's residents. Heat pumps can provide more consistent heating and cooling than traditional systems. This is because heat pumps can both heat and cool the air, while traditional systems can only heat or cool the air.

However, switching to heat pumps would also have some costs. Heat pumps are more expensive to install than traditional systems. Additionally, heat pumps require more space to install, so they may not be suitable for all homes in the community.

Part 1: Objectives Diagrams

Fundamental Objectives Hierarchy:

Reduce HOA costs

Reduce HOA carbon footprint

Improve resident comfort

Means Objectives Network:

Reduce HOA energy costs

Reduce HOA reliance on fossil fuels

Switch to renewable energy sources

Provide more consistent heating and cooling

Part 2: Alternatives and Consequence Table

Alternatives:

  1. Maintain the status quo and continue to use traditional heating and cooling systems.
  2. Switch to heat pumps for the community's heating and cooling needs.
  3. Implement a combination of energy efficiency measures and renewable energy solutions.
  4. Do nothing and take no action to reduce the HOA's carbon footprint.

Consequence Table:

Attribute Alternative 1 Alternative 2 Alternative 3 Alternative 4
HOA energy costs High Low Medium High
HOA carbon footprint High Low Medium High
Resident comfort Medium High Medium Low
Installation cost Low High Medium Low

Assumptions:

  • Heat pumps are more efficient than traditional heating and cooling systems.
  • Heat pumps have a lower carbon footprint than traditional heating and cooling systems.
  • Heat pumps can provide more consistent heating and cooling than traditional systems.
  • Heat pumps are more expensive to install than traditional systems.
  • A combination of energy efficiency measures and renewable energy solutions would be less expensive to install than heat pumps, but it would not be as effective in reducing the HOA's carbon footprint.

Part 3: Uncertainty and Probability Distributions

Uncertainty in HOA energy costs:

The HOA's energy costs will vary depending on a number of factors, including the weather, the cost of electricity, and the efficiency of the community's buildings.

Probability distribution for HOA energy costs:

I will use a triangular probability distribution to represent the uncertainty in HOA energy costs. The minimum value will be the HOA's current energy costs, the most likely value will be the HOA's estimated energy costs with heat pumps, and the maximum value will be the HOA's estimated energy costs with traditional heating and cooling systems.

Uncertainty in HOA carbon footprint:

The HOA's carbon footprint will vary depending on a number of factors, including the type of energy used to heat and cool the community's buildings, the efficiency of the buildings, and the weather.

Probability distribution for HOA carbon footprint:

I will use a normal probability distribution to represent the uncertainty in HOA carbon footprint. The mean value will be the HOA's estimated carbon footprint with heat pumps, and the standard deviation will be 10% of the mean value.

Part 4: Multi-Attribute Utility Model

I will use an additive utility model to evaluate the alternatives. The utility function for each attribute will be linear.

Utility weights:

I will use the following utility weights:

  • HOA energy costs: 0.4
  • HOA carbon footprint: 0.3
  • Resident comfort: 0.2
  • Installation cost:
