How It Works
Your Energy Disclosure Report tells you how efficient your home is and helps you prioritize projects that make the most impact and save you the most money, with free energy advisors who can guide you through the process.
The Energy Score rates your home’s energy efficiency — the higher your score on the 0–100 scale, the more efficient your home is. A more efficient home is more comfortable to live in and has lower energy bills. The score is determined by evaluating your home’s physical characteristics, so it is fairly compared to homes of different types and ages. The report also recommends ways to make your home more energy efficient — which would increase the score and save you money on your utility bills.
Key Features of the Energy Score
The score is designed for Minneapolis’s older, existing housing stock. Every home can achieve the top score of 100 by completing cost-effective energy improvements:
Focuses on the four areas of existing homes that have the highest energy savings potential:
Generating the Energy Score
The score is generated from data collected during the Truth in Sale of Housing (TISH) evaluation. This data is used to determine the efficiency of the home in four key areas — attic insulation, wall insulation, heating system and storm windows — and these results are totaled to determine the home’s overall score. For example, a home with no wall insulation will score low in this area, which results in a lower overall score.
Data Collection and Score Calculation
The report outlines the typical cost for recommended improvements. The typical cost is calculated from evaluating thousands of local contractor estimates for the recommended improvements. For attic and wall insulation, these costs are specific to the house type (one-story, two-story, etc.) and square footage of the home, as these characteristics have an impact on project cost. The actual cost for these improvements will vary based on the specifics of the home and the project, but this is the typical project cost for similar homes.
The yearly bill savings outlined on the report are calculated using algorithms that are approved by the State of Minnesota. These algorithms are used by utilities to calculate energy savings for projects that receive a utility rebate. The bill savings outlined on the report represent the average range that has been calculated for these projects.
