HVHZ preconstruction · Miami-Dade & Broward

Know what fits the building — before you bid, buy, or build.

HVHZ code checks, a verified product catalog and a 3D model of your building, turned into estimates, permit packages and feasibility studies.

How it works

Every deliverable starts from the same three parts.

Inside the EC System, an HVHZ code engine, a verified product catalog and a 3D model of the building answer one question on every job: what fits this building?

HVHZ code engine

The wind speed at the exact address, HVHZ status, and the design pressure every opening needs, from ASCE 7-22 with Florida Building Code overrides.

Product catalog

Approved windows, doors and envelope products, with the ratings and size limits from their own approval. Manufacturers list for free; nobody pays to rank.

3D building model

Every opening and wall measured once, from the drawings or a 3D scan of the building, and reused for every deliverable on the job.

What fits this building?

Contractors

Takeoffs and estimates, shop drawings, NOA and permit packages.

Owners & investors

Envelope feasibility and interior fit studies; the fit study comes with a 3D walkthrough.

Manufacturers & dealers

Your products shown wherever they fit, and packages drawn with them.

One check, live today.

The Florida wind load calculator runs the HVHZ code engine and the product catalog on your window and door schedule: the design pressure each opening needs, and the approved products that meet it. Free, and no account needed to see the answer.

For contractors

Hand us the work, or give your team the tools.

Two ways to work with us, and many contractors use both.

We do it for you

Your outsourced estimating and permitting team.

A monthly plan, finished documents, nothing to learn. Send us the drawings and get back takeoffs, estimates, shop drawings and permit packages from a team that does HVHZ envelope work every day.

  • Plans from Estimation to Enterprise, mapped to your monthly volume
  • Every job also lands in your EC System workspace: a project record that is there when you want it, and that you never have to open

Your team does it

Software for your own estimators.

The same checks our team runs, in your own EC System workspace.

  • Free: wind load checks, catalog product matching, saved projects and progress tracking
  • Pro: reports and quotes under your logo, plus a cost calculator
  • Studio: your own conceptual design deliverables — layouts, utility loads and 3D walkthroughs. In early access.

Done-for-you plans grow with you.

Every contractor on this ladder started somewhere lower. The window sub who added doors. The glazing crew that took on prime contracts. Start where you are.

Frequently asked

What people ask us first.

What’s the difference between a Miami-Dade NOA and a Florida Product Approval?

A Miami-Dade Notice of Acceptance (NOA) is issued by Miami-Dade County after a product passes the county’s TAS testing protocols. A Florida Product Approval carries an FL# and is valid statewide — but on a High-Velocity Hurricane Zone job in Miami-Dade or Broward, only if the approval explicitly covers HVHZ use. An FL# without HVHZ coverage is one of the most common reasons an envelope submittal gets rejected. The full breakdown →

Do you prepare shop drawings and permit packages?

Yes. Takeoffs and schedules of values start with the Estimation plan, and a typical window and door takeoff comes back within 48 hours. Shop drawings, NOA and Product Approval packages, and permit packages come with Compliance. See what each plan includes →

Who seals the design pressures and shop drawings?

When a package needs a seal, we coordinate it with a Florida-licensed professional engineer we work with, as part of the engagement. Final responsibility stays with the contractor of record and the sealing engineer, as on any permit job.

Do you work outside Miami-Dade and Broward?

South Florida’s HVHZ is our focus, but our team works remotely and can support envelope work in other markets — talk to us about your project.

Is EnergyCheck software or a service?

Both. On the done-for-you plans our team does the work and delivers finished documents; Pro and Studio are software for your own estimators. Every account comes with an EC System workspace.

Do you work with property owners and investors?

Yes, on residential and light-commercial projects, done for you with a fixed scope and a fixed fee. We tell owners and investors which approved envelope products fit a building’s location and geometry, and for interior build-outs we 3D-scan the space and deliver a conceptual layout, the utilities it needs, a code-compliance report and a 3D walkthrough. Studies are quoted per project. How owner studies work →

Start here

Start with one project.

Send us one job. Contractors: we’ll do the takeoff and schedule of values as a paid trial, so you can judge the work before committing to anything bigger. Owners and investors: tell us about the property and we’ll scope and quote a study.

We follow up within one business day — but the fast path is the phone.
