If you're modeling in Revit or ArchiCAD, add data tags with passive performance fields. We label walls, windows, and roofs with SHGC, U-value, and solar orientation data in the model — the visuals help non-technical stakeholders understand passive design better.

We priced two envelope packages — one with full passive integration, one with reactive systems. Lifecycle costs favored passive envelope by year 7 even with higher day-one spend. Client ran with it after finance team stepped in.

We staged a walkthrough in a completed passive building — brought client to feel the thermal comfort firsthand. Cost us one flight, but it sealed the deal for high-mass strategy they were skeptical about before.

We built a 1:10 cardboard model and did time-lapse daylight studies with light meters. Low-tech, high-impact. Sometimes analog validation beats digital simulations for buy-in.

We now coordinate with sustainability early to ensure structural loads accommodate passive strategies. Overhangs, slab thermal mass, and internal masonry all need early input. It avoids VE later when budget pressure rises.

You can simulate envelope variants using WUFI or THERM to model condensation and thermal bridging risks. Even without full-scale models, showing risk of mold or material degradation wins the argument early.

O&M impact is tangible. We logged maintenance calls in two buildings with and without external shading — the unshaded site had double the fan coil faults in peak season. Share FM data if the client won’t trust the model.

We don’t wait for energy models to prove shading. It’s baked into our spec as a non-negotiable. Facade zones with >40% glazing get integrated shading by default — either fins, louvers, or low-E. We’ll negotiate the form, not the function.

Sell it with capital deferral logic. We argued that shading reduced HVAC plant size enough to offset PV oversizing in year 5. Decision shifted from capex pain to lifecycle benefit, which aligned with client’s financing model.

We built a 1-week thermal snapshot using EnergyPlus linked with Rhino geometry. Even at DD-10, it showed a 4°C indoor delta between glazed vs. shaded exposures. Used those visuals in client deck — they bought in immediately when they saw overheating under real sky data.

We use adaptive comfort overlays on early-stage parametric models to validate passive massing. The envelope isn’t final, but we can prove thermal lag benefit via sinusoidal dampening factors in peak internal temps. If you frame it as resilience, not savings, clients get it faster.
