Find the lowest-cost system mix that still clears code.

Projects that lock a system spec before running the numbers leave $4,100 per unit in avoidable cost on the table, on average. Run a full Optimization Check before your HVAC, glazing, and insulation specs are finalized, before your budget is set, before the number reaches your GC.

Optimization Summary

Illustrative data, not a real project. Swap for a real product capture once available.

Every component decision, priced before you choose it.

One model, run before you lock a spec, not three separate takeoffs.

Evaluate every viable system mix, not just the first one

Run HVAC, glazing, insulation, and solar/battery combinations against your budget and code target at the same time, instead of testing one spec, waiting on a report, and hoping it holds.

Start from what you already know

Enter your building type, target budget, and baseline system assumptions once. Buildwiser uses them as the starting point for every combination it evaluates, not a generic default.

Watch the recommendation update as you change a spec

Swap a component and the code and cost math re-runs immediately. See the recommended spec next to your baseline, not in a follow-up report three weeks later.

See why this mix wins, not just what we picked

Every evaluated combination is ranked by cost and code margin, so you can see exactly why Buildwiser recommends one system mix over another, not just take its word for it.

Compare every package side by side

See your original spec next to a mid-efficiency and a high-efficiency package, with the cost delta and compliance margin for each, before you lock anything in with your GC.

Frequently asked questions

What components does this actually optimize?

HVAC systems, glazing specs, insulation R-values, and solar or battery sizing: evaluated together against your budget and code target, not one spec at a time.

How does it balance cost, code, and performance?

Every combination is scored against your budget ceiling and code minimum simultaneously. The recommended package is the lowest-cost option that still clears compliance, not just the cheapest option available.

Can I lock in a spec and re-optimize the rest?

Yes. Lock a component you've already committed to, a specific HVAC vendor for example, and Buildwiser re-optimizes glazing, insulation, and the remaining systems around it.

Does this replace a mechanical engineer?

No. Buildwiser narrows thousands of combinations down to a short list before your MEP engineer produces stamped drawings. It replaces the guesswork, not the engineer of record.

What happens after my first optimization run?

Your recommended package saves to your account immediately, with the full comparison ready to review, export, or share with your GC.
