Architectural diffusers
Engineered to perform.Designed to inspire.
Air distribution shouldn’t compromise architectural vision. EffectiV combines distinctive designs, exceptional finishes, and high-performance engineering to create diffusers that complement the most ambitious spaces—without sacrificing comfort or efficiency.
- Energy efficiency
- Thermal comfort
- Indoor air quality
Room First
The room should drive the system.Not the other way around.
The room comes first.Everything else follows.
Great buildings deserve more than good equipment. At EffectiV, we start with what matters most: comfort, indoor air quality, and energy efficiency. Then we engineer the air distribution to deliver.
Conventional approach
The system is designed upstream; room-level performance often receives less attention.

Room First
01 · Where it starts
EffectiV – Start with the room, not the product.
A room, its occupants, a window, one diffuser in the ceiling. Everything that matters for comfort is decided right here.
02 · Conventional diffuser
Cold air falls on people. Warm air stays at the ceiling.
A standard diffuser dumps supply air. The result is drafts, stratification, and a system working harder for less comfort.
03 · EffectiV high-induction diffuser
Same airflow, mixed. One uniform temperature.
Air hugs the ceiling, entrains room air and mixes before it reaches anyone. No drafts, less stratification, less energy.
04 · Verified
We don’t promise it. We measure it.
Every design can be validated by CFD simulation per ASHRAE 62.1 before anything is installed.

Room first
Three measurable outcomes. One strengthened last link.
The diffuser is the last link of the HVAC chain, usually the cheapest and the weakest. Strengthen it and the whole system performs better.
Thermal comfort
High induction and even mixing: fewer drafts, less stratification, occupants who stay productive.
Read more 02Energy efficiency
Better mixing lowers the load on equipment. Every diffuser becomes a lever for savings, not a compromise.
Read more 03Indoor air quality
A higher Ez factor means more effective ventilation, as defined in ASHRAE Standard 62.1.

What if the duct itself became the diffuser?
BREEZ turns exposed ductwork into an engineered air distribution system. Every perforation pattern is computed for the room, in heating and in cooling, by SelectiV.
The science of air mixing
We don’t just make diffusers. We prove they work.
