Core compliance
What the plan reviewer asks for.
Energy calculations
Required by most building departments to show energy-code compliance (Florida Form R405 and equivalents). We model the home and deliver the forms the reviewer expects.
From $100Manual J / S / D reports
HVAC load, equipment sizing and duct design so the system is right-sized and the mechanical reviewer is satisfied.
From $100EPL card (Florida)
The Energy Performance Level display card required with most Florida residential permits and builder submittals.
With energy calcsWindow & door compliance
U-value, SHGC and wind-load compliance for the fenestration package, required in most Florida and IECC jurisdictions.

Beyond the minimum
Green certifications and incentives.
For builders and owners who want the performance documented: certification support, ratings, and the paperwork that unlocks rebates and credits.
LEED-Silver Equivalency™
A no-plaque equivalency assessment and report for projects that want LEED-level performance documented without the USGBC fee structure.
From $4,500HERS, ENERGY STAR, Zero Energy Ready
Documentation and consulting for builders targeting HERS ratings, EPA ENERGY STAR certification or DOE Zero Energy Ready Homes.
QuotedIncentives & rebates
Technical paperwork for utility rebates, DOE programs and 45L tax credits, plus ROI reports for energy upgrades.

How a house loses energy
Three layers, one envelope.
Most people know energy efficiency matters to the utility bill; fewer have the whole picture. The building envelope works as three layers that have to agree with each other, and the mechanical system has to be sized for what the envelope actually does. That is where architects, engineers and the HVAC designer need to work from the same numbers.
- Insulation levels and continuity
- Window U-values and solar heat gain
- Air sealing and tested leakage
- Roof color and ventilation
- Wall assembly and thermal mass
- Right-sized HVAC and duct design
- Layer 1
Weather layer
The outermost layer: siding, cladding and roofing. It keeps wind, sun and rain off the structure; the color and type of roofing alone changes how much solar radiation the building absorbs.
- Layer 2
Insulation layer
The primary driver of thermal performance. It slows heat transfer by conduction, convection and radiation; the right R-value depends on climate, assembly and what the rest of the envelope does.
- Layer 3
Airtight layer
The continuous interior barrier that stops air leakage and the moisture it carries. Weatherstripping, caulk, tapes and membranes, tested rather than assumed.
Questions
Do I need energy calculations for my permit?
In Florida and most IECC jurisdictions, yes, for new construction, additions and many alterations that change the envelope or the mechanical system. The building department will not issue the permit without the compliance forms.
What do you need from me?
The plan set (or sketches with dimensions), window and door schedule with U-value and SHGC, insulation values, HVAC equipment data if selected, and the address. The intake lists it; most calcs issue in 2–3 business days from a complete set.
Can you make my design more efficient, not just compliant?
Yes. Compliance is the floor. Where you want to go further, we model options (envelope upgrades, equipment, orientation) and show the cost and payback, and we document programs like ENERGY STAR, HERS and Zero Energy Ready when a project targets them.
Which states?
Energy calculations follow each state's adopted code; we prepare them for Florida (R405) and IECC-based jurisdictions across the 38 states where the firm is licensed.
