Since 1996, Technosim has delivered rigorous, engineer-certified energy consulting for commercial, institutional, and industrial buildings across Canada. Every project is led by Master's-level professional engineers.

ASHRAE Level I, II & III
A Technosim energy audit delivers a rigorous, quantitative assessment of your building's energy consumption. Our licensed engineers analyze all energy-consuming systems — HVAC, lighting, envelope, and controls — to identify, prioritize, and quantify efficiency improvement opportunities.
Site inspection and utility bill analysis to identify low-cost/no-cost measures and flag areas for deeper study.
Detailed analysis of all energy systems with capital cost estimates, payback calculations, and a prioritized action plan.
Engineering-level analysis with sufficient accuracy for capital investment decisions. Full simulation and detailed cost models.
Standards & Tools

Whole-Building Modelling
We build calibrated energy models of your facility using industry-standard simulation engines. Our models predict annual energy consumption, validate design choices, and generate the compliance documentation required for code and energy efficiency certification.
EA Credit 1 compliance modelling per ASHRAE 90.1 for LEED-NC, LEED-CI, and LEED-EB certification.
Feasibility studies for commercial buildings and performance evaluation using NRCan's RETScreen Expert — including clean energy analysis and M&V.
Comparative analysis of envelope options, HVAC strategies, and control sequences to maximize energy performance.
Standards & Tools

Restoring Peak Building Performance
Over time, building systems drift from their designed performance due to changes in occupancy, control sequences, and component wear. Our recommissioning process systematically identifies and corrects these deficiencies, restoring efficiency and comfort without capital expenditure.
Review of as-built drawings, building automation data, and maintenance records to identify system deficiencies.
On-site testing of HVAC controls, sequences of operation, economizer cycles, and zoning to verify intended function.
Correction of faults, optimization of setpoints, and M&V monitoring to confirm and sustain energy savings.
