SEAI Certified BER Assessors for Commercial Buildings

Commercial BER Certificates

We help Irish businesses, landlords and developers meet regulatory obligations by providing certified Commercial Building Energy Ratings (BERs). Our SEAI-registered assessors deliver accurate asset ratings and advisory reports to support property transactions, improve efficiency, and maintain compliance across all non-domestic building types.

What is a Commercial BER Certificate?

Commercial Building Energy Ratings (BERs) are a legal requirement for non-domestic buildings in Ireland. They provide an ‘asset rating’ that measures your building’s energy efficiency on a scale from A to G, based on its design and systems rather than actual usage. This standardised assessment helps buyers and tenants understand potential energy costs, identifies improvement opportunities, and demonstrates regulatory compliance. A BER isn’t just a legal obligation for property owners—it’s a valuable tool that can enhance property value, reduce operational costs, and showcase your commitment to sustainability.

When is a Commercial BER required?

A Commercial BER certificate must be provided when a non-residential building is being constructed, sold, or rented. The certification remains valid for 10 years unless significant changes are made to the building’s fabric or systems. Exemptions include Protected Structures, Temporary Buildings, Places of Worship, Non-Residential Agricultural Buildings with minimal heating requirements, and Buildings Formally Scheduled for Demolition under current regulations.

  • New Construction – All newly built commercial properties
  • Property Sales – When selling any commercial building
  • Rental Agreements – For new commercial leases
  • After Renovations – Following major building upgrades

What is a Commercial BER used for?

A Commercial BER determines a property’s energy efficiency, providing details on energy usage (kWh/m²) and carbon emissions (kg/m²) per year. This standardised assessment helps potential buyers and tenants understand expected operating costs and compare different properties. The rating serves as a benchmark for property valuation, regulatory compliance, and identifying cost-effective energy efficiency improvements that could enhance building performance.

  • Property Transactions – Informs buyers and tenants
  • Cost Prediction – Estimates energy expenditure
  • Building Comparison – Enables efficiency benchmarking
  • Improvement Planning – Identifies upgrade opportunities

How Your Commercial BER is Calculated

A comprehensive Commercial BER assessment involves specialised methodology and expert analysis. Our qualified assessors use the standardised Non-Domestic Energy Assessment Procedure (NEAP) and approved software to transform your building’s physical characteristics into an accurate energy rating.


How We Calculate Your BER

Our assessors survey your property and input the collected data into iSBEM, the official software used to calculate the BER. The process includes analysing your building’s design, construction elements, heating, ventilation, lighting systems, and more. The software then calculates your building’s energy performance on the standardised A to G scale, providing clear insight into its efficiency.

Understanding BERs vs DECs: What’s the Difference?

Building Energy Rating (BER)

A BER is a standardised assessment of a building’s energy efficiency based on its design and fixed systems. It uses typical assumptions about occupancy and energy use, considering features like insulation, heating, ventilation, and lighting. Valid for ten years, a BER is legally required when constructing, selling, or leasing a commercial building. It measures design performance rather than real-time or operational energy consumption.

Display Energy Certificate (DEC)

A DEC is an operational energy rating that reflects the actual measured energy use of a building over a 12-month period. It captures real consumption during occupancy and benchmarks performance against similar buildings. DECs must be renewed annually and are required for public buildings over 250m² and commercial properties over 500m². It includes both regulated and unregulated energy use, promoting public transparency and energy awareness.
