Residential Studio

Room-scale thermal design.

Set the climate, space and comfort target. Size a PCM kit, then review the design.

Step 01 — Climate

Where is the room?

Choose a country on the map, then refine by city.

European markets

Supported cities

Selected locationParis · France

P90 climate fit: Strong fit

7.8 night hours in Paris fall below a 24°C PCM phase point; 6 hours are required for recharge.

Step 03 — Your room

Residential room model

This Studio is only for homes and individual rooms. Commercial projects now use a separate calculation workspace.

Step 04 — Supplemental cooling

Studio sizes passive measures and PCM first. Only after that quantity is fixed does it add the minimum active control needed for the remaining comfort gap.

Automatic active-cooling recommendation

Natural night cooling or PCM-only capacity cannot maintain the selected comfort target. Studio therefore includes TROTEC PAC 2010 SH for up to 2 hours per day. Its price is not included in the PCM quote.

Step 05 — What do you already own?

Anything you own is marked “Reuse yours”. The rest gets “Partner pick” — never a forced bundle.

PCM quantity, fan quantity, price and comfort results appear only after this calculation.

Step 02 — Thermal screening

Public calculation basis

P90 design warm dayERA5 2015–2024 · 24 hoursThe 90th-percentile daily peak, with night temperature and solar conditions from the same warm-day band.

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.

PCM quantity is calculated against this single active model.

PCM airflow mode

Day and night speeds are controlled separately. Boost automatically returns to a lower mode after 2 hours.

DIY quantity explorer

See how the room responds, then choose your PCM quantity.

The chart keeps the room and climate fixed, so you can see the difference PCM makes. The Studio recommendation stays marked as you explore.

Dynamic temperature response

Same room, with and without your selected PCM quantity

Only the PCM quantity changes between the two lines. Room, climate, shading, night ventilation and airflow stay the same; active cooling is left out.
