• Blend technical depth with real-world impactcombine simulation expertise design consulting and market education to influence how architects and engineers achieve energy efficiency and comfort.
• Work at the intersection of innovation and leadershipcollaborate across R&D sales and marketing while mentoring peers and defining modeling standards that set industry benchmarks.

What does a Sr. Building Performance Engineer do

Technical Sales and Modeling Support

• Partners with A/E firms and ESCOs from concept modeling through high-fidelity IESVE simulations to analyze design options and quantify financial cases to incorporate Armstrong products in building energy designs.
• Quantifies annual energy/cost impacts peak-load reduction sizing changes and first-cost trade-offs for Templok and new solutions.
• Performs load calculations; support system selection and sizing (coils fans pumps) and psychrometrics; draft BAS sequences to leverage Templok within ASHRAE 55 comfort guidelines.
• Supports code-compliance modeling and submittals (ASHRAE 90.1 PRM/Appendix G IECC Title 24) and LEED EA documentation leveraging Armstrong products on customer projects.
• Builds early-phase screening tools and VE scripts/post-processing to accelerate building performance evaluations and highlight the contributions of Armstrong solutions.
• Leads IESVE studies across building types and climates; define scenarios and present results and recommendations to technical and executive audiences.

Technical Marketing & M&V

• Performs calibrated simulations (ASHRAE Guideline 14/IPMVP) for real projects; write concise M&V reports and case studies; present results to technical and non-technical audiences.
• Translates results into clear value propositions/metrics for the customer: peak reduction hours-of-exceedance PMV/PPD economics (payback LCCA) etc.
• Contributes to grid-interactive load-shifting and demand/cost analyses where applicable.

Product & Tooling Development

• Leverages IESVE simulations and project experience to inform product roadmap.
• Establishes QA/QC checklists acceptance criteria and reference VE files to ensure reproducibility of modeling results.
• Develops a library of IESVE simulation results and parametric runs as quick-lookup reference cases to inform product performance estimates across building/climate scenarios.
• Develops rough-order performance tools calibrated to VE results and first-principles heat-transfer methods for early-phase estimation and sales enablement.
