Building Energy Modelling & EnergyPlus Simulation
Detailed, dynamic energy models that tell you how a building will actually perform — before you commit to a design, a retrofit, or a funding application.
Simulation-led decisions, not rules-of-thumb
Building Energy Informatics uses EnergyPlus and industry-standard building energy modelling (BEM) tools to build a detailed digital model of your building's fabric, systems and operation. That model becomes the evidence base for design decisions, compliance submissions and retrofit business cases — replacing guesswork with simulated, testable outcomes.
We work across new build, major retrofit and existing-stock modelling, for commercial, industrial, public sector and residential-scale projects, in Ireland, Northern Ireland and the UK.
- ✓Maximise efficiency — Identify inefficiencies and quantify the impact of design or retrofit options before money is spent.
- ✓Meet regulation — Modelling structured to support TGD L, NZEB, Part L and EU energy performance compliance.
- ✓De-risk funding & tender submissions — Clear, defensible evidence for grant applications and procurement panels.
- ✓Tailored to your building — Models reflect your actual design, location, occupancy and systems, not generic assumptions.
How we deliver this service
Data collection
We gather architectural, systems and operational data — from drawings, BMS exports or site survey.
Model build
A detailed EnergyPlus/BEM model is constructed to reflect fabric, HVAC, lighting and occupancy.
Simulation
We run scenarios across design options, weather years and operational conditions.
Analysis
Results are interrogated for savings potential, compliance margin and risk.
Reporting & support
A clear report with recommendations, plus support through design, funding or tender review.
Sectors we support
Commercial buildings
Offices, retail and hospitality projects optimising design and operating cost.
Industrial facilities
Manufacturing and warehousing sites reducing energy spend and downtime risk.
Local authorities & government
Public buildings needing modelling evidence for compliance and funding.
Residential developments
Multi-unit schemes balancing comfort, compliance and construction cost.
FAQs
What software do you use for building energy modelling?
We primarily use EnergyPlus and IES-VE for dynamic thermal simulation, supported by custom scripting for scenario automation and results analysis.
Can building energy modelling support a planning or tender submission?
Yes. We produce modelling reports and evidence packs structured for planning authorities, funding applications and public procurement submissions.
Do you model existing buildings as well as new design?
Yes. We build calibrated models of existing buildings from survey and metered data, as well as design-stage models for new build and major retrofit projects.
