Computerized energy management systems have been in use for a long time now. In the nineties, these were offline systems based on energy management control systems (ECMS). Recent developments in IT have also affected energy management domain. Today's building automation systems (BAS) handle all the energy and equipment related tasks and provide operating information and control interfaces to other facility systems including facility management systems. Modern cloud-based energy use analysis and audit software can run large building simulations and equipment design programs. The software requires the input of weather data, operating times, and other energy-consuming parameters such as number and type of lights and equipment, the efficiency of various devices, etc. as well as the parameters of the building shell such as wall construction, insulation levels, amount of window area, etc. It will then simulate a year of building operation (or whatever cycle is chosen), and develop energy consumption and energy bills. When the simulation model has been built, various efficiency improvements to the building envelope or to building equipment can be fed into the software and receive the identified saving opportunities. Combined with financial analysis features this will help select the most cost-effective energy conservation opportunities (ECOs). Research has shown that buyers on average spend $15-20 more per every $1 on annual energy savings. That means that

Weatherization Assistant is a suite of 4 energy audit tools developed by Oak Ridge National Laboratory to help the interested parties implement the US DOE Weatherization Assistance Program. The 4 constituent tools are:
- National Energy Audit Tool (NEAT) for site-built, single-family homes
- Manufactured Home Energy Audit (MHEA) for mobile homes
- Multifamily Tool for Energy Audits (MulTEA) for multifamily buildings
- Health and Safety Audit - for single-family homes (including mobile homes)
The first 3 tools identify cost-effective energy conservation measures (ECM) for a home or building, taking into account site weather conditions. local retrofit measure costs, area fuel costs, and specific construction details. Health and Safety Audit tool is aimed at the situations when a dwelling unit is being weatherized or undergoes an energy-efficiency retrofit or remodeling job. NEAT and MHEA are desktop-based while MulTEA and Health and Safety Audit are web-based. Currently, NEAT and MHEA are in the process of porting into web-based apps. The executable for desktop-based apps can be downloaded from the website. For web-based apps, you need to contact the stuff to get access credentials.
Green Training provides on-site and online courses and consultation related to green technologies. Their energy audit software called Easy Audit doesn't require internet access. It is designed for use on tablets with a stylus but runs on any computer or device that runs MS Excel. The main features of Easy Audit are:
- generates detailed, on-site audit reports
- retrofitting recommendations
- easy-to-understand report format
- MS Excel-based platform
- Automatically calculate fresh air levels and building airflow standards
- Works on MS Windows
- Utility bill analysis
- Energy Performance Graphs
- ROI calculations
- Typical payback periods
- Automatic report generation
it's a mobile app geared towards the realtors. It asks several questions about the home, like the home's insulation or the types of kitchen appliances then produces a custom report that contains recommendations on how to make the property more energy efficient. For example, it may suggest caulking around windows or adding insulation. HomeSelfe also tells how much money could annually be saved on energy bills by making each upgrade, so homeowners or realtors can prioritize each upgrade.
To demonstrate the value of energy audit, the realtor could open up HomeSelfe app on his/her mobile device and walk the homeowner through an energy audit. The realtor, then, could explain to sellers that they are able to increase the listing price of their home by just following the recommendations by the app. A word of warning though, the primary aim of this app is lead generation and social marketing hence the energy auditing feature set is not particularly rich although it's free.
