The P90 climate basis is preset. Describe the building, then calculate.
PCM usage and preliminary comfort screening will appear after calculation. Engineering prices are confirmed by the local channel partner.

Step 01 — Climate
Where is the room?
Choose a country on the map, then refine by city.
Supported cities
P90 climate fit: Conditional fit
10.0 night hours in London fall below a 24°C PCM phase point; 6 hours are required for recharge.
Step 03 — Your room
This dedicated workspace keeps building projects, authorization and reports separate from the residential Studio.
Open residential StudioCan the AHU use cool outside air at night?
This changes transmission, solar and internal heat gains — not just floor area.
Step 04 — Supplemental cooling
Commercial and public-building active cooling remains subject to engineering review; a consumer portable AC is not added automatically.
Baseline case: no active room-cooling capacity is credited.
Model credit: 0 W room heat removal. PCM quantity is not reduced.
Step 05 — What do you already own?
Anything you own is marked “Reuse yours”. The rest gets “Partner pick” — never a forced bundle.
PCM usage and preliminary comfort screening appear only after this calculation. Engineering prices remain partner-quoted.
Step 02 — Thermal screening
Public calculation basis
One public model is used for every PCM quantity. It represents roughly the hottest 10% of warm-season days and is a decision estimate, not a performance guarantee.
Extreme multi-day heatwaves can prevent overnight PCM regeneration; active cooling is the correct fallback in that condition.
Complete the building information below, then calculate. PCM usage is hidden until that step.
Day and night speeds are controlled separately. Boost automatically returns to a lower mode after 2 hours.
