When you join CIMA+, we welcome you to a place that you can call home.

CIMA+'s Buildings team is renowned for its expertise in designing high-quality buildings. We are committed to providing the most cost-effective solutions to engineering challenges and offer a diverse range of projects from the initial planning stages to design and construction. CIMA+ cultivates career growth and provides opportunities as unique as you are. With a constant desire to offer our clients the best possible service, we have set up a team of specialists dedicated to high-performance projects to support our clients and design teams across Canada.

We are looking for aSenior Energy Efficiency Engineer to join our Buildings team in Ottawa. The successful candidate will play a key role in delivering energy audits, energy management, building optimization, commissioning and recommissioning, energy efficiency studies, and decarbonization projects for institutional, commercial, municipal, and federal government clients throughout the National Capital Region and across Canada.

The position will combine hands‑on technical analysis with site investigations, building systems assessment, energy conservation measure (ECM) development, commissioning, client interaction, and project management. The successful candidate will work closely with CIMA+'s mechanical, electrical, controls, sustainability, and building performance specialists to identify and implement practical solutions for existing buildings.

Primary Responsibilities

• Lead and performenergy audits and building performance assessments, including ASHRAE Level 1 and Level 2 energy audits and detailed investigations of building systems.
• Conduct site investigations and assess existing HVAC, hydronic, plumbing, electrical, lighting, controls/BAS, and other energy-consuming systems.
• Analyze utility bills, interval data, submetering data, BAS trends, equipment operating data, and building operating schedules to identify energy‑saving and operational improvement opportunities.
• Identify, develop, and evaluate energy conservation measures (ECMs) related to HVAC optimization, controls, heat recovery, electrification, heat pumps, lighting, envelope improvements, equipment replacement, and operational improvements.
• Perform engineering calculations to quantify energy, demand, operating cost, and greenhouse gas savings associated with proposed measures.
• Support energy management programs, including energy performance tracking, benchmarking, energy action plans, ongoing monitoring, and continuous improvement initiatives.
• Lead and support commissioning, recommissioning, and retro‑commissioning activities, including functional performance testing, BAS and control sequence reviews, trend analysis, deficiency identification, and verification of corrective actions.
• Review building automation system sequences and operating strategies and develop recommendations to improve equipment scheduling, setpoints, reset strategies, ventilation, temperature control, and overall system performance.
• Support measurement and verification (M&V) activities to confirm the performance and savings of implemented energy efficiency measures.
• Develop building decarbonization and electrification strategies, including evaluation of heat pumps, heat recovery, hybrid heating systems, thermal energy systems, and associated electrical infrastructure requirements.
• Support energy modelling and building performance simulation activities and interpret modelling results to inform retrofit and capital planning decisions.
• Perform technical and economic evaluations of energy efficiency projects, including implementation costs, simple payback, lifecycle cost analysis, and prioritization of measures.
• Prepare energy audit reports, feasibility studies, commissioning reports, technical memoranda, presentations, and implementation roadmaps.
• Work directly with clients, facility managers, building operators, contractors, controls specialists, and multidisciplinary design teams to understand operational challenges and develop practical solutions.
• Support implementation of recommended measures through design, tender, construction, commissioning, and post‑implementation verification where required.
• Manage projects and coordinate scope, budget, schedule, deliverables, and multidisciplinary resources.
• Provide technical guidance and mentorship to junior engineers, EITs, analysts, and technologists.
