P.1 Energy Efficiency Project ME 418 // Spring 2024 Background and Problem Statement: Using your calibrated building energy model from H.4, we will now proceed to explore ways to improve the energy efficiency of the home. You can assume that your original model is accurately calibrated for this analysis, and you can assume that all cost parameters in BEopt are accurate. The objective of this study is to explore multiple building modifications and determine which combination of improvements will result in the greatest energy savings for the least upfront cost. You will use the “Optimization” analysis option in BEopt. Instructions for Optimization Analysis: 1. Begin with your calibrated model from H.4. Save as a new file and clear any saved run results. 2. Navigate to the Options Screen and select the Optimization analysis option from the drop-down menu. 3. Select multiple options for building parameters by holding down the control key as you make selections. You can click and drag to select multiple options at once. 4. Navigate to the Site Selection menu. Update your utility rate to reflect your real rate. You can choose a "Detailed” rate and select from OpenEI options as well. 5. Run the optimization model. This may take quite some time depending on how many and which options you chose. Deliverable: Submit a recommendation of building modifications for energy savings. This report does not need to be long, but it needs to be thorough. Include the following: • • Brief description of the house, including a figure of the baseline monthly energy consumption profile from your calibrated H.4 model. Be sure to include total estimated energy consumption and the associated cost (ensure you use a consistent utility rate between “baseline” and "optimized"). Include a screenshot of the BEopt house model as well for reader reference. A summary of the selected options for which you will optimize your model, including a justification of why you selected them. Be realistic according to the condition of your building. For example, if the model is of a building that doesn't yet exist, it's perfectly fine to optimize the frame and roof designs. However, if you are modifying an existing home, it is impractical to replace 4" studs with 6" studs. ○ Include at least 10 different options from multiple categories (e.g., Windows and Doors, Space Conditioning, Schedules, etc...) Optimization results, including the specific parameters to be changed and the associated costs (from BEopt). Include the two figures (properly labeled and discussed) produced by BEopt after it completes the analysis. Discuss the results and recommend a course of action. You do not need to choose the "optimal" result provided by BEopt, as you may have alternative criteria for your selection, but you must justify your choices. Recall that this assignment is worth 20% of your grade. The simulation and analysis are easy, as BEopt will do all the work. Therefore, your grade will be determined by the quality of your report and your application of sound engineering judgement in selecting optimization options. Page 1 of 1
