Software Tools

There are a range of tools available. Lists provided here are not intended to be comprehensive, and inclusion here or in the package is not an endorsement from LBNL.

There are three main tool types, with some overlap between. For the package, you will use a benchmarking tool, as well as either a Monthly Data Analysis tool or an Interval Data Analysis tool, depending on what type of data is available for your site:

One Benchmarking Tool and either One Monthly Data Tool or One Interval Data Tool
Monthly Data Analysis Benchmarking Interval Data Analysis

If you only have utility bill or monthly energyuse data, then you will want to choose from the following tool.

Most regions of the country will only have access to monthly data, including NY, FL, MI, MO, VI & WI.

Some customers in AZ, CA, IL, MA, MN, TX & WA may only have access to monthly data.

Noesis

Update: Noesis is no longer offering their free energy management tools. Noesis Pro may be of interest to those managing a large number of buildings and focuses primarily on financing of efficiency measures.

A set of online energy management and benchmarking tools for commercial buildings and portfolios. Tutorial video at here.

Wegowise *

Online energy and water management and benchmarking tool focused on cross-portfolio comparison for multifamily and small commercial buildings and portfolios. Wegowise connects directly to utility accounts and interfaces with Portfolio Manager to retrieve Energy Star Ratings. An extended free trial is available for demonstration partners (typically membership is $6/building/month for commercial buildings).

GreenQuest

Free online tool for tracking energy and water use for a single building (one building per login account). For a portfolio, EnergyCap offers tracking of 25 meters starting from $49/month.

Utility website with plotting capabilities (where available). Online account portals can display daily, weekly and monthly energy use and benchmarks against peer buildings.

FirstView

Free online tool benchmarks buildings against peers and provides automated analysis of monthly data to identify potential areas of inefficiency based on the building's energy signature. Limited to office buildings with gas heat and electric cooling.

All users will want to benchmark building performance to compare energy use with peers.

If your building type is not eligible for an ENERGY STAR ranking, you will want to calculate the Energy Use Intensity (EUI) using one of the tools to the left, and then you can use that to track performance and EnergyIQ to compare with the EUI of peer buildings.

The following tools can be used for benchmarking:

Portfolio Manager

Free online tool calculates Energy Star Rating and energy use tracking for commercial and industrial buildings and portfolios. Portfolio Manager will be updated in June 2013.

WegoWise *

Online energy and water management and benchmarking tool focused on cross-portfolio comparison for multifamily and small commercial buildings and portfolios. Wegowise connects directly to utility accounts and interfaces with Portfolio Manager to retrieve Energy Star Ratings.

EnergyIQ

Free online tool for benchmarking against a customizable group of peer buildings using various metrics. This tool allows you to view the range of values of energy use metrics for different building types, including normalizing energy use by factors such as floor area, employees or restaurant seating. Limited energy use tracking of buildings or portfolios is available. Energy IQ can retrieve data from Portfolio Manager.

EUI Calculator

An Excel spreadsheet, from the State of Oregon, designed to calculate Energy Use Intensity EUI) for schools, it is a good general use spreadsheet for calculating EUI. You enter the monthly data for electricity and gas and the program will convert them both to a total EUI in kBtu/sf-year.

If you have interval (hourly or sub hourly) electricity data, first you will want to use a benchmarking tool, and then an interval data analysis tool.

Interval data will be available for most buildings in CA and TX as well as some buildings in AZ, IL, MA, MN, WA and possibly other locations. Check information on interval data access here.

If your interval data file has the .csv file extension, use:

Energy Lens by BizEE Software Ltd *

Software add-in for Excel available for download. Tool can display daily load profiles over a month compared with average profiles, or plot trends in daily weekly or monthly energy use over time. This tool is easiest to use with data in a .csv file, but .xml files can also be imported into Excel.

Energy Ai *

Analysis of 6-13 months of interval electricity data for a single meter (load). The report highlights use patterns and irregularities. Free trial will be available for demonstration partners (typically for $20 per pdf report).

ECAM (more advanced)

While designed to analyze interval data from multiple system points, this free add-in to Excel for Windows can be used to visualize building level interval data by month or by day type (day of week, weekend, holiday). This tool is easiest to use with data in a .csv file, but .xml files can also be imported into Excel.(more advanced)

If your interval data file has the .xml file extension, use:

Green Charts

Very simple, free online tool to display monthly, daily and hourly energy use data, that allows the user to move easily between different months and days. This tool requires data in an .xml file no larger than 2.6MB. Tutorial video here.

Energy Ai *

Analysis of 6-13 months of interval electricity data for a single meter (load). The report highlights use patterns and irregularities. Free trial will be available for demonstration partners (typically for $20 per pdf report).

Leafully

Simple, free, online tool to display interval data on different timescales. Can connect with a number of utilities through Green Button Connect for automatic updating, or you can upload a .xml file.

Building Energy Fingerprint

Simple, free online tool to analyze Green Button data (.xml file). This tool generates a custom report with several graphs that may help identify trends in interval electricity data.

Green Button Grapher

Very simple, free, online tool to display interval energy use data. This tool can also display the average weekend and weekday load profile. This tool requires data in an .xml file and may have trouble loading very large files (larger than about 8MB).

Sample Data

Here is a PGE (Pacific Gas & Electric) Green Button XML files that can be used for sample data. These files are from the U.S. Department of Energy Green Button PGE sample data website. There are many more example files there if you want to experiment with different data sets:
