Yes, properties anywhere in the world can use Portfolio Manager. Tracking changes in energy and cost over time can be accomplished effectively for any property, no matter the location. Note: properties located outside of the US are not eligible to earn ENERGY STAR certification unless they are owned by the US Government.
Benchmarking international buildings is recommended as a best practice because:
- Regular benchmarking of energy consumption can help you find and identify energy waste across your portfolio.
- Reports that show your total energy by fuel type and your weather normalized energy metrics will provide a valuable way for you to organize all buildings, you can sort by energy consumption to find the top and bottom performers in your Portfolio and use this to share with others.
- Even though source energy and the ENERGY STAR score are based on US reference data, they both provide a consistent benchmark that can be used to track your own properties over time. Even if buildings in a different country generally score higher or lower, the score is always computed according to a fixed methodology, so it is still a uniform way to track performance over time.
There are some metric limitations to keep in mind when benchmarking internationally:
- ENERGY STAR score is still compared to US buildings. There could be systematic differences (e.g. different building codes or different regional climate ranges) that could make the score different in another country.
- Source Energy is still compared to US buildings. The source conversion factors depend on the predominant methods of energy generation in the country. A country with a higher proportion of wind or hyrdo-electric power may have different source energy conversions than the US.
- International GHG factors are not available. At this time we do not offer GHG emissions factors that are specific to any countries besides the US and Canada. Therefore, the emissions that will be shown for buildings in other locations will reflect the US average GHG emissions rates.
