Energy Modeling
Advanced dynamic simulation using IES-VE and HAP — translating architectural concepts into high-performance, energy-efficient assets from the earliest design phases.
At Montreal Group LLC, our comprehensive energy modeling services translate architectural concepts into high-performance, energy-efficient assets. Utilizing advanced dynamic simulation tools such as IES-VE and HAP, our engineering team evaluates whole-building energy performance, thermal comfort, and code compliance from the earliest design phases.

From early concept through final compliance documentation — integrated at every stage of design.
Geometry & Baseline Development
We translate architectural 3D massing and CAD drawings into analytical simulation models. This includes defining precise thermal zones, orientation parameters, local weather data, and operational schedules.
Envelope & Fenestration Optimization
We analyze building envelope performance — evaluating wall insulation, roof R-values, window-to-wall ratios, and solar heat gain coefficients (SHGC) — to minimize thermal bridging and cooling loads.
HVAC Systems Sizing & Efficiency Analysis
We perform rigorous peak load calculations and dynamic simulations to size mechanical equipment accurately, ensuring optimal part-load efficiency, improved indoor air quality, and reduced lifecycle energy consumption.
Energy Conservation Measure (ECM) Evaluation
We test various design strategies — such as daylight harvesting, variable refrigerant flow (VRF) systems, heat recovery, and high-efficiency lighting — to identify the most cost-effective path toward net-zero energy goals.
Green Building Rating Compliance
We provide full documentation, credit calculations, and compliance reporting for international rating systems, including LEED and the Global Sustainability Assessment System (GSAS).
Project Visuals & Models
Energy simulation outputs and 3D thermal models from live projects.
Industry-Standard Software Tools
Our simulations run on the same platforms used by leading global engineering consultancies.
IES-VE
Integrated Environmental Solutions — Virtual Environment. Industry-standard dynamic thermal simulation for whole-building energy and comfort analysis.
HAP
Hourly Analysis Program by Carrier. Used for HVAC equipment sizing, peak load calculations, and ASHRAE compliance reporting.
