About Us
At IES, we value People, Purpose, and Innovation. We offer a flexible and supportive working environment and the opportunity to work with a team of friendly, interesting, and diverse people from across the globe, who are passionate about what we do.
Over the last 30+ years, we have built a solid reputation as the leading global innovator in integrated performance-based analysis and are now home to the most advanced building physics analytics team in the world. Our innovative software solutions and expert consultancy services empower designers, engineers, building owners, and operators to deliver more efficient, comfortable, and sustainable buildings through design, retrofit, and operation. Our dedicated Research & Innovation team ensures our technology and expertise remain best in class and at the forefront of innovation.
The Role
We are looking for a Building Services Commissioning Consultant to join our expanding international consulting team. You will play a key role in sustainability and LEED-focused projects, with a primary emphasis on LEED Commissioning, Operational Energy Analysis, Energy Auditing, and Measurement & Verification.
This role involves working with real-world building performance data, including BMS trend data and energy meter data, to identify inefficiencies and support building optimisation. You will contribute to post-occupancy energy reviews and energy audits, helping clients understand how their buildings are performing against design intent and benchmark targets, and identifying practical opportunities to reduce energy consumption and carbon emissions.
This role is well suited to someone with a general building services design background who is keen to develop specialist experience in LEED commissioning, energy auditing, operational energy analytics, and M&V. Project-based training will be provided.
You will work across projects in Ireland and internationally, with opportunities (though not a requirement) to spend time working in different global locations.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

What You’ll Do
- Support and deliver LEED Commissioning and Measurement & Verification projects across a range of building types and scales
- Conduct and support energy audits across commercial, public, and institutional buildings, assessing building fabric, mechanical and electrical systems, controls, and operational practices to identify energy-saving opportunities
- Prepare detailed energy audit reports in line with recognised standards (e.g., ASHRAE Level audits and SI 426 compliance audits), including prioritised recommendations with indicative cost and carbon savings
- Develop and implement Measurement & Verification Plans in line with IPMVP protocols, tracking and reporting energy savings against an established baseline
- Analyse utility and sub-meter data to assess building energy performance, identify consumption anomalies, and quantify savings achieved through energy conservation measures
- Review and interrogate BMS trend data to evaluate the performance of HVAC systems, including AHUs, fan coil units, chillers, boilers, and heat recovery systems
- Identify control strategy issues, setpoint anomalies, and mechanical faults through data-driven analysis, and prepare clear technical reports with actionable recommendations for building operators and clients
- Benchmark building energy performance against recognised standards and best practice figures, and support clients in developing roadmaps for energy reduction
- Review and interpret design and construction documentation, including HVAC, mechanical, and electrical system designs
- Support LEED energy modelling activities where required
- Work collaboratively with internal teams and external project stakeholders
- Develop your technical capability through structured project-based training, including use of IESVE software
