Heating and cooling are the largest sources of energy use in your home. The Before2050™ Energy Use Calculator can give you a quick and easy assessment of your home’s total energy use and show you how it compares with other homes in Newton. This app can be used by any Newton homeowner who receives their own property tax bill and gas and/or electric utility bills.
Get a More Complete Picture of Your Home’s Total Energy Use
Utility companies generate a ‘compare with your neighbors’ summary of your gas or your electrical use, but not both together, resulting in an incomplete picture. Before2050™ combines all your energy use information on your computer or mobile device, updates it automatically, and allows you to compare your home’s usage with others in Newton.
How Before2050™ Works
Upon entering your address and utility information, you will receive an Energy Use Intensity (EUI) number, a number that shows how much energy you use for the size of your home. The greater the insulation and energy efficiency, the lower the EUI. Before2050™ will compare your EUI to other EUIs in its database–by size of homes, age, neighborhood, etc.–and display the information in simple graphs. You’ll also have links to the ways you can take action to lower your EUI.
Here’s What You Need
- a PC computer with Windows 10 or higher, or an Android 7 or later smartphone (Apple devices are not yet supported)
- the Before2050™ app
- your gas and/or electricity billing account numbers
Before 2050™ is intended for all computer skills levels and does not require any technical knowledge about energy use or efficiency. All data entered is strictly confidential.
Pilot participants will be asked to fill out a brief survey on their experience using the app. Your opinion matters! Your feedback will help make Before2050™ better as we move toward a full launch. Thank you.
What is the purpose of the app?
The Before2050™ app is designed to help homeowners understand their home’s energy use. The app will calculate an Energy Use Intensity (EUI) number based on your total annual energy use and the size of your home. The app retrieves the size of your home from the publicly available Newton Assessor’s Database.
What is the Energy Use Intensity (EUI) number?
The EUI is a measure of energy efficiency of your home. The more efficient the home the smaller the EUI. The EUI is calculated in two steps: First, the electricity and natural gas use are converted to a common metric unit called a Btu; Second, the total annual energy (in Btu) consumed in the operation of your home is divided by the square footage of your home.
Why is the Energy Use Intensity (EUI) number important?
The EUI is the total annual energy (in Btus) consumed in the operation of your home divided by the square footage of your home. This includes heating, cooling, lighting, charging, and anything else that uses gas of electricity to operate. The largest impact on your EUI are the level of insulation and air sealing of your home, and the efficiency of your heating and cooling equipment. The smaller the EUI of your home, the more energy efficient–and better for your wallet and the environment. This EUI number can be used to see how your energy use compares to other homes in Newton. As the app is fully developed and the database of EUIs of Newton homes becomes more robust, you will be able to compare your home to the average in Newton, as well as averages by zip codes, houses of similar age, houses of similar size, etc.
Who can sign up?
The pilot is open to any Newton homeowner who receives their own property tax bill and gas and/or electric utility bills. We may make the app available to other residents at a future date.
Why should I sign up?
The Before2050™ app is under development. Your participation in the pilot will give us valuable feedback and help us improve the app’s performance. Also, we hope understanding your Energy Use Intensity (EUI) will enable you to make the best choices in improving your home’s energy efficiency.
How do I sign up?
You need a computer with a Windows 10 or higher operating system, or an Android 7 or higher smartphone. Download the Before2050™ app to your computer or smartphone and launch. Follow the prompts for entering your street address and account numbers–and you’re done! You can view your Energy Use Intensity (EUI) number and how it compares with other pilot participants. Your EUI comparisons will become more meaningful as more people participate in the pilot, so make sure to check the app occasionally to improve your understanding of your home’s annual energy use.
How long will the process take?
It will take about 3-5 minutes for you to enter your information and obtain your Energy Use Intensity (EUI) number, and the online followup survey will take 5 minutes.
Where do I locate my account numbers?
Locate your account number on your Eversource bill: Locate your National Grid account number and the access code:
How will my data be used?
The sharing of your gas and electricity account numbers allows Before2050™ access to your usage data. The data will be used to provide homeowners with information on their home’s energy use compared to other homes in Newton. Your personal name and address will be kept strictly confidential, and the data received related to your home will be used only for statistical analysis. The information will not be used for commercial purposes.
Who will be able to see my data?
Only the homeowner will be able to see their personal data. Homeowners will be able to see the aggregate Energy Use Intensity (EUI) of homes but they will not be able to see the names and addresses associated with individual EUIs. App developers will be able to view the of homes, but the name and address of the homeowners will remain anonymous.
Will I need to enter data regularly?
You only need to enter your information once at registration and the app will update your data automatically each calendar year.
I only have a Mac or an iPhone. Is an iOS version being developed?
Depending on the success of the Before2050™ pilot program, an app for Apple computers and phones may be developed in the future.
