Dillon Consulting is a proudly Canadian, employee-owned firm founded in 1946. With over 1,100 employees and a strong presence in Calgary and Edmonton, we specialize in guiding large building owners through complex retrofit and energy transition work. In 2023, we acquired IESC — a leading integrated energy management and building sciences firm — significantly expanding our Energy Solutions capabilities.
For retrofit clients, we bring a performance-first approach built around four core strengths.
- Integrated, Multi-Disciplinary Solutions: We bridge the gap between architecture, building sciences, and mechanical/electrical engineering. This ensures that building envelope upgrades work in perfect harmony with HVAC and smart control overhauls, preventing the “siloed” mistakes that plague complex retrofits.
- Data-Driven Financial Rigor: We do not just provide a list of repairs; we provide a defensible financial roadmap. We utilize established methodologies like ASTM E917-compliant Life Cycle Cost Analysis (LCCA) and Uniformat II to develop detailed Total Cost of Ownership profiles. We factor in energy escalation, carbon pricing, and maintenance burdens so your capital planning is audit-proof.
- Funding & Grant Optimization: Retrofits must make financial sense. Our teams align our audits and energy modeling with stringent provincial and federal guidelines—such as the Municipal Climate Change Action Centre (MCCAC)—to ensure your projects maximize eligibility for future funding and implementation grants.
- End-to-End Execution: From calibrated hourly energy models (using DesignBuilder/EnergyPlus) and ASHRAE Level 2/3 audits to construction oversight and final commissioning, we provide a seamless transition. Our goal is to minimize operational downtime while transforming legacy infrastructure into high-performing, climate-resilient assets.
