Building HVAC makers build the equipment; we supply the phase-change core. OEM partners develop air conditioners, heat pumps, and energy-storage systems around our PCM — a leading appliance brand for water heaters, a European heat-pump maker for heat-pump heat storage — plus radiant PanSure® climate mats for the building envelope.
Our downstream customers are building HVAC and energy-system manufacturers. They take our phase-change materials and build the product — air conditioners, heat pumps, water heaters, and energy-storage systems — owning the equipment design and the system patent.
Passive Edge supplies the PCM chemistry, encapsulation, and phase-point tuning; the partner ships the product. It lets OEMs add latent thermal storage without becoming a materials company.
A major home-appliance manufacturer integrates our PCM into water heaters — banking heat so hot water holds through demand peaks and off-peak charging windows.
A European heat-pump company builds thermal storage on our materials — storing heat-pump output to decouple comfort from when electricity is cheapest and cleanest.
The same UltraST core drops into air conditioners, heat pumps, and building energy-storage systems. Bring the equipment; we tune the phase point and chemistry.
1. Indoor temperature follows the sun. Modern lightweight construction heats up fast in the afternoon and cools fast at night. Without thermal mass, the room temperature tracks the outdoor swing — and the HVAC chases it all day.
2. Peak demand is expensive and dirty. Cooling load peaks exactly when the grid is most stressed and electricity is most carbon-intensive. Shaving and shifting that peak is worth more than the kWh alone.
3. Concrete mass is crude. Heavy structure adds memory but you can’t tune where it acts. A phase-change layer concentrates that thermal memory at one temperature — the comfort band — and packs it into a thin mat.
Inspired by the PCM that NASA put in spacesuits to hold astronauts in their comfort band, a PanSure® mat behind the finish turns each surface into a storage terminal: it absorbs the daytime heat peak and releases it after hours — with no change to the existing system.
Two ways to give a building thermal memory — a passive mat that retrofits behind any finish, or an active store that charges off-peak and dispatches on demand.
A thin, flexible PCM mat installed behind drywall, ceiling, or floor. It works entirely passively — charging from the room when it’s warm, releasing back when it cools — and retrofits without touching the HVAC.
A compact solid-state PCM store that charges from off-peak power or a heat pump and dispatches heating or cooling into the loop when it’s needed — decoupling comfort from when energy is cheapest and cleanest.
From the radiant mat in production today to a family of phase-change building elements in development.
The radiant PCM terminal for wall, ceiling, and floor. Passive, retrofit-friendly, and the backbone of the smart climate system.
A smart PCM energy-saving cooling system for telecom base stations and equipment rooms — cutting cooling energy where heat runs around the clock.
Phase-change building elements — glazing, curtains, and decorative panels — that fold thermal storage into the finishes themselves. Patents pending.
At the Solar Decathlon China net-zero building competition in Zhangjiakou, fifteen zero-carbon houses became part of a national new-energy demonstration base.
Working with two of China’s leading architecture schools, Passive Edge supplied the PCM wall storage & temperature-control system for both Qiju 3.0 (Xi’an University of Architecture & Technology) and Pitched House (Chongqing University). Both buildings posted strong energy performance and were widely recognised.
The more of the following you can share early, the faster we can return a useful response. None of these constitute a commitment from either side.
We work in clearly-bounded stages. No stage commits the next. Each produces something you can use internally — even if you don’t proceed with us.
You share building type, comfort target, HVAC, tariffs, and available surfaces. We return a written fit assessment within ~5 business days.
Joint review of phase point, mat placement, and whether an active Thermal Vault adds value — with predicted swing-reduction and load-shift figures.
A scoped pilot in a representative room, instrumented for indoor temperature and energy use across day / night cycles.
Pilot data review against predicted performance. Decisions to scale across the building or portfolio are made on measured evidence.
Phase-point options across the comfort band, latent capacity per m², install detail for wall / ceiling / floor, and damping performance data.
Integration patterns for homes, offices, and base stations, the Solar Decathlon case detail, and load-shift sizing worksheets.
Editable template covering instrumentation, day / night protocol, success criteria, and reporting against predicted swing and energy.
Our team will respond with a fit assessment, the relevant application note, and a proposed pilot room if there is a match.
