In 2026, walls have learned to manage heat. We present Phase-Change Materials (PCM)—an innovative solution for passive lobby climate control. These materials can store and release colossal amounts of thermal energy when transitioning from solid to liquid state and back. At Reception Space, we integrate PCM into wall panels and ceilings, transforming finishes into giant thermal accumulators. We explore why air conditioners are becoming shadows of the past.
The Magic of Phase Change: How It Works
2026 technology utilizes microencapsulated paraffins or salt hydrates embedded into the structure of lobby plaster or panels. When the room temperature rises above a comfortable 22°C, the PCM begins to melt, actively absorbing heat from the air. In a Reception Space lobby, this allows temperature to be kept stable even on the hottest noon without fan coils. The walls literally 'soak up' the heat, providing guests with a cool touch.
Nighttime Heating: Energy Return
Natural balance without costs
When the temperature drops in the evening, the PCM begins to crystallize, smoothly releasing the heat stored during the day back into the lobby space. In Reception Space projects, this creates a 'thermal inertia' effect. The building requires 40% less energy for nighttime heating as the walls themselves act as soft radiators. It's the most ecological way to maintain a microclimate, inspired by material physics rather than compressor power.
