Energy code compliance · Performance path

Pass the energy code by simulation, at a price that fits the project.

When the prescriptive checklist won't work for your design, we build the whole-building energy model that proves compliance. ASHRAE 90.1 Appendix G, the Energy Cost Budget method, or IECC total building performance, delivered as a reviewer-ready report for a fixed fee.

How we work with you

Tell us who you are

The model and the code are the same for everyone. Who hires us, who stamps and what you get out of it depend on your role.

For MEP engineers

Your energy modeling team. You keep the stamp.

Outsource the performance-path model without giving up the project. We work as your subconsultant, build the model from your drawings and schedules, and hand back a package that's quick for you to review and stamp.

How it works

  1. Send the drawing set and equipment schedules.
  2. We model and send a preliminary result within a week.
  3. If the margin is thin, we show which mechanical changes buy the most.
  4. You get the full package plus a one-page sign-off summary of key inputs, baseline rules applied and QA checks.
  5. You stamp and submit. We answer the reviewer's comments.

What you get

  • Performance-path capacity without hiring or training a modeler
  • Work you can review fast, with every input traced to your sheets
  • Your client relationship stays yours
For architects

Keep the design. We'll show it meets the code.

When glazing, a curtain wall or an unusual envelope won't pass prescriptively, the whole-building model can trade it against better systems elsewhere. Bring us in early and you'll know where the design stands before it's locked.

Who hires us
You, or your MEP engineer
Who stamps

Check a design

How it works

  1. Share design development drawings, wall sections and the window schedule.
  2. Within a week, we tell you whether the design passes and by how much.
  3. If it's close, we test envelope and system options so you choose what to keep.
  4. We coordinate inputs with your MEP engineer.
  5. The designer of record reviews and stamps. We handle plan-review comments.

What you get

  • Early answers on window-to-wall ratio and assemblies
  • Options ranked by cost, not just pass or fail
  • The same model ready for LEED
For owners and developers

A clear answer before permit, and no upgrades you don't need.

We work for you, independent of the design team. The model shows whether the building complies and which upgrades actually move the result, so you don't pay for envelope or equipment premiums the code never required.

Who hires us

Who stamps
Your architect or engineer of record

No one on your team able to stamp? Say so when you ask for a quote and we'll agree on a stamping path before work starts.

How it works

  1. Send what your design team has, or put us in touch with them.
  2. We model and report the result within a week.
  3. We show the lowest-cost ways to comply or to add margin.
  4. Your architect or engineer of record reviews and stamps the package.
  5. We answer plan-review comments through approval.

What you get

  • An independent check on your design team's assumptions
  • Upgrade choices ranked by cost and benefit
  • A model you can reuse for LEED or a decarbonization plan
For contractors and design-builders

Value-engineer without breaking compliance.

Substitutions happen. When equipment, glazing or controls change, we rerun the model quickly, so you know the change still complies before you buy it, not after the plan reviewer asks.

About 2 days
Test a substitution

How it works

  1. Send the permit set and the substitutions you're considering.
  2. We build or update the compliance model and confirm the current margin.
  3. We run each substitution and report its effect in about 2 days.
  4. The engineer of record reviews and stamps the updated package.
  5. We answer plan-review comments.

What you get

  • Substitutions tested before purchase orders go out
  • Fewer permit delays from a failed resubmittal
  • Option runs priced up front
Why simulate

The prescriptive path says no. The model can say yes.

Prescriptive compliance checks each component against a fixed limit. The performance path looks at the whole building, so a strong HVAC system or better lighting can make up for the glass wall the architect wants to keep.

Keep the design intent

High window-to-wall ratios, unusual systems and atriums that fail component limits can still comply when the rest of the building performs.

Spend money where it counts

We show which upgrades actually move the result, so you don't buy envelope or equipment premiums the code never needed.

Clear the plan review

Reports follow the format reviewers expect, with baseline and proposed inputs side by side and every exceptional calculation documented.

What we do

Energy and carbon simulation for buildings that have to perform

Technical analysis for architects, engineers, owners and builders working on commercial and industrial projects.

Featured service

Energy code compliance, performance path

Whole-building models under ASHRAE 90.1 Appendix G, 90.1 Section 11 (ECB) and IECC C407, with every compliance document completed and plan-review support. Your designer of record reviews and stamps, which keeps our fees low and our review independent.

Scope, process and pricing →

Certification

LEED and green building energy modeling

Minimum and optimized energy performance documentation for LEED and other rating systems, built from the same model as code compliance when the timing lines up.

Design support

Design-phase energy analysis

Early massing, envelope and HVAC comparisons that give the design team numbers while decisions are still cheap to change.

Industrial

Commercial and industrial technical analysis

Process loads, ventilation, heat recovery and equipment studies for warehouses, plants and other buildings that don't fit standard templates.

Carbon

Decarbonization planning

Electrification and efficiency roadmaps that show the emissions, energy cost and capital trade-offs of each step for a building or a portfolio.

The cooperative

Built to be owned by the people who do the work

Energy Consulting Collective is a founder-led LLC with one clear plan: grow into a worker-owned cooperative. The modelers who build your project will share in the firm and in its decisions.

For clients, that means the person who answers your plan reviewer is the person who built the model, and the firm is run for the long term rather than for a buyout.

  1. Today: founder-led practiceOne senior energy modeler, every project done in-house.
  2. Next: first worker-membersNew modelers join on a defined path to ownership.
  3. Then: worker-owned cooperativeConversion to a cooperative structure with one member, one vote.
