Energy Compliance & Building Performance
Building Compliance & Energy Performance
Delivered through our specialist consultancy division EBSNI, we provide building compliance and energy performance services for residential and commercial projects across Northern Ireland, supporting buildings from early design through to final certification.
Our team delivers SAP calculations, SBEM energy modelling, detailed heat loss surveys, ventilation strategies and acoustic assessments, ensuring Building Regulations and energy targets are considered from the outset rather than checked retrospectively.
We also provide airtightness testing, thermographic surveys and acoustic testing across Northern Ireland, verifying that the completed building matches the original design assumptions and meets required performance standards.
By integrating energy compliance, construction and renewable system design, we help avoid costly redesigns and ensure the finished building performs as intended.
