Energy Efficient
New HomesA new home that has earned the ENERGY STAR label has undergone a process of inspections, testing, and verification to meet strict requirements set by the US EPA. ENERGY STAR certified homes use 15-30% less energy than typical new homes while delivering better comfort, quality, and durability.

Benchmark Your Data Center’s Energy Efficiency
Compare your data center nationally
In June 2010, EPA ENERGY STAR began to include data center building types in Portfolio Manager – the interactive energy management tool. By inputting a year’s worth of monthly IT and total building energy use into Portfolio Manager, data center operators can:
- Compare their data center’s energy efficiency to others. Portfolio Manager generates a rating from 1–100 relative to hundreds of other data centers nationwide.2
- Earn ENERGY STAR Recognition. With a rating of 75 your data center earns the ENERGY STAR certified building designation. View a list data centers that have been certified and profiles of data centers designated ENERGY STAR Low Carbon IT champions.
- Estimate their data center’s carbon footprint. Portfolio Manager calculates your building's greenhouse gas emissions – including carbon dioxide, methane, and nitrous oxide – consistent with the Greenhouse Gas Protocol.
- Track and report progress at their data center. Portfolio Manager allows you to examine data center energy use over time, evaluate savings from retrofit measures, and generates a Statement of Energy Performance (SEP) report.

1 Server closets or computer training rooms are not considered data center space. At least 50% of the building's gross floor area (excluding parking lots and garages) must be data center to meet the data center building type. Please review general and mixed used building type eligibility requirements.
2 A rating of 50 indicates that your data center performs better than 50% data centers nationwide.
