NBI is happy to announce a new, free tool to help building owners and others quickly evaluate the potential energy savings associated with existing retrofit strategies. The Retrofit Savings Estimator is a web-based analysis engine that uses basic building information to automatically perform a set of custom building energy simulations.
Designed for commercial building owners, managers, tenants, and anyone else who’s interested in learning more about the performance of a building, the tool is easy to use, simple to understand, and highly customizable. You won’t need to pay anything or even register to begin. The focus is on existing building retrofits; a wide variety of building types can be examined, from offices to supermarkets to schools.To get started, you’ll need some basic building data: things like total building area, building type, year of construction, and what kind of heating or cooling equipment you have. This information is entered primarily through drop-down menus; you don’t need to know numerical values or equipment specs. The intent is to utilize information that’s easily available to owners and managers. If you’re missing a particular piece of data, you can fall back on a customized default assumption.The results allow you to investigate how much energy you could save by implementing promising groups of energy savings measures (building improvements). The tool identifies a set of the most impactful measures based on basic building characteristics and identifies potential energy savings associated with those upgrades. The tool can also predict how much energy you could save, as a percent of current usage, by implementing a custom set of measures. You can define a subset of the recommended measures to determine the impact of those choices. For example, in the sample report shown here, we’re looking at a package that includes HVAC distribution and lighting upgrades, among others measures, but excludes demand-controlled ventilation, windows, and heat recovery measures. You can clearly see how much energy can be saved by implementing selected measures. Once you’ve scoped out your deep retrofit opportunities, you can print the results and use them to compare multiple buildings in your portfolio against each other. Comparison enables you to prioritize retrofit opportunities, define the scope of potential projects, and find out how much energy could be saved from a deep energy retrofit. Ready to try it out?
