Smart software to improve EPC ratings and accelerate building energy efficiency

OnEfficiency was launched in 2020 and uses a property’s energy performance certificate (EPC) to identify costed energy efficiency interventions to improve the EPC rating.

OnEfficiency is a Software as a Service (SaaS) platform that compares and simulates the impact of deploying a range of energy efficiency measures within your portfolio.

This energy efficiency feasibility assessment tool can also be used as the first step to scoping the cost and potential for achieving net-zero, both for individual buildings and across a whole portfolio.

The first stage identifies whether your property (or any properties within your portfolio) is rated in the lower Band F or Band G under the Minimum Energy Efficiency Standard (MEES) Regulations. Then, using a traffic light system, we can address any ‘Red’ or ‘Amber’ warnings and suggest improvements to increase the property’s rating.

The data held for each building includes zoned description and usage, heating, lighting, hot water, construction details, glazing, plant efficiency, and the EPC expiry date.

The Software re-simulates this data and generates a full list of all possible improvement measures, detailing:

• Possible improvements
• Cost estimate range
• Potential energy savings
• Potential carbon savings
• Discounted payback
• Impact on the EPC rating

Current government guidance retains EPC E as the existing minimum and proposes EPC B from 2031 for privately rented non-domestic buildings over 1,000m² in England and Wales.
