Sustainable Design Engineer

Building Energy And Performance Modeling Practitioner

A technically skilled, outcomes-driven practitioner in building energy and performance modeling who helps project teams in making design decisions that improve people's lives through healthier, more resilient, lower-carbon buildings. Exercises independent judgment to develop whole-building simulations and engineering analyses across building types and scales, translating data into clear, actionable recommendations from early concept through delivery and post-occupancy verification. Brings broad knowledge of high-performance sustainable design principles and tools, contributes original solutions, and strengthens firmwide capability through collaboration, research, and knowledge sharing.

Develops whole-building dynamic thermal and energy simulation models across diverse building types and scales, including advanced mechanical systems evaluations and architectural-performance integration (daylighting strategies, lighting controls impacts, and façade thermal/moisture response)

Performs detailed engineering analysis to reduce energy consumption and associated GHG emissions across design, construction, and operations, aligned with integrated project performance goals

Executes comfort studies, energy simulation, daylight simulation, solar shading analysis, and renewable energy evaluations, and produces analysis-based recommendations that inform decisions by architects, engineers, contractors, and operators

Supports DesignGreen and firm sustainability leadership by contributing modeling and analysis that integrates design-performance, energy-modeling, and operations-modeling practices across projects

Predicts building energy use and savings versus baseline using whole-building simulation with clear assumptions, and supports post-occupancy evaluation and performance verification using industry-standard calibration procedures

Provides Life Cycle Cost Analysis (LCCA) and Life Cycle Assessment (LCA) for design alternatives, applying appropriate economic parameters and documenting tradeoffs tied to design and operational decisions

Reviews professional literature to identify innovation opportunities that improve energy efficiency and building performance using new and existing technologies, and contributes market-relevant implementation ideas

Produces technically rigorous, graphically clear reports, calculations summaries, and presentation materials that translate analysis into actionable design direction

Collaborates with design teams and technical disciplines to promote integrative sustainable strategies and leverages complex datasets to support design decisions and research objectives

Supports specialized project and enterprise research on energy, environmental, carbon, and sustainability topics, and contributes to methods, data collection, and documentation as needed

Delivers internal training content and knowledge sharing on building science fundamentals and energy analysis software applications

Participates in team meetings to coordinate project delivery, surface technical issues early, and align modeling work with project schedules, scopes, and performance outcomes
