How can you compare the energy efficiency of different buildings using energy benchmarking?

3 What are the steps of energy benchmarking?

In order to effectively conduct energy benchmarking, it is important to first define the scope and objectives of the project. Additionally, data and information related to the buildings must be collected and verified, such as size, type, use, occupancy, location, and energy consumption. Once this is done, an appropriate tool and method for the buildings must be chosen, such as Energy Star Portfolio Manager, Building Energy Quotient, or Energy Performance Indicator. Then energy performance metrics and indicators for the buildings can be calculated and compared, such as energy use intensity, energy efficiency rating, or energy performance score. After analyzing and interpreting the results and findings of the project, energy efficiency measures and actions for the buildings can be implemented and evaluated.

4 What are some common energy benchmarking tools and methods?

There are different energy benchmarking tools and methods available for different types and sizes of buildings. For example, the Energy Star Portfolio Manager is a free online tool that allows you to measure and track the energy and water consumption of your buildings, with a 1-100 score rating their energy efficiency. The Building Energy Quotient program provides a comprehensive assessment of the energy performance, using a letter grade (A+ to F) to rate the energy efficiency. Additionally, the Energy Performance Indicator calculates the energy efficiency of your buildings, using a value between 0 and 1 to indicate their efficiency.

5 What are some tips and best practices for energy benchmarking?

To ensure the accuracy, reliability, and usefulness of your energy benchmarking project, it is important to define the scope and objectives clearly and realistically. Collecting and verifying data related to your buildings must be done carefully and consistently. Additionally, choose the appropriate energy benchmarking tool and method based on building characteristics and needs. Calculate and compare energy performance metrics for your buildings using the same units and time periods. Analyzing and interpreting the results of your energy benchmarking project should be done critically and objectively. Finally, implementing and evaluating energy efficiency measures for your buildings should be based on evidence and feedback.
