ZEROvã.
Design that reaches zero.
Zero It is the universal word for zero—it comes from the Arabic *sifr*, and is understood the same way in Madrid, Dubai, and Sydney.
Va it is a verb in Spanish and Italian: to advance, to move towards.
ZEROvã it literally means moving toward zero: not a status certified at the end, but an active process that begins with the very first stroke of the project.
It is also the direct application of OmniaCurva’s CERO PARAMÉTRICO: optimizing the building’s form via algorithms so that every design decision points toward the same goal. LEED, BREEAM, VERDE, Passivhaus—not as mere formalities, but as a destination.
We integrate LEED, BREEAM, VERDE, and Passivhaus certifications from the very first stroke of the project.
Sustainability is not an add-on; it is part of the design.
Four systems, one team
Officially accredited in LEED, BREEAM, VERDE, and Passivhaus. The most suitable certification depends on the project, not on the consultant's familiarity.
LEED
U.S.Green Building Council
A global benchmark. Recognized by ESG funds and international developers. Levels ranging from Certified to Platinum.
BREEAM
BRE Global
Reino Unido
Reino Unido
The most widely adopted European standard. Particularly valued in investment funds and corporate assets.
VERDE
GBCe
Spain
Spain
Spanish certification with full local regulatory recognition. Ideal for subsidized housing (VPP), renovation, and public works.
Passivhaus
Passive House Institute
The highest standard of comfort and efficiency.
Up to 90% lower energy consumption.
A single team. From the preliminary design to the certification seal.
The problem we solve.
Sustainability arrives late.
In most projects, certification is considered at the end, once design decisions have already been made.
The result: higher costs and a poorer outcome.
Certifying without designing doesn't work.
A certified building that does not start with good bioclimatic design consumes more, is less comfortable, and generates energy bills that the certification did not predict.
The client doesn't know where to start.
LEED, BREEAM, VERDE, Passivhaus:
four systems with different requirements.
Without expert advice from the outset, the developer makes the wrong choice—or fails to choose at all.
How we work.
01
Feasibility analysis
Before the project.
Which certification, with what objectives, and with what budget.
Which certification, with what objectives, and with what budget.
02
Integration into the design
During the project.
Decisions regarding form, orientation, the building envelope, and systems.
Decisions regarding form, orientation, the building envelope, and systems.
03
Documentation and registration
Throughout the project.
Document management and team coordination.

04
Verification and stamp
At the end.
Inspection, certification, and delivery of the seal to the developer.
Inspection, certification, and delivery of the seal to the developer.
La diferencia con otros consultores: participamos en las decisiones de diseño, no solo en los formularios.

The full certification experience,
without the cost of a large firm.
Fair price. No middlemen.
No intermediary markups · no large-firm overhead · direct contact with the person signing off on the project.
Pre-evaluation
Initial project assessment and certification feasibility, including a preliminary report.
Gestión integral
Support from design through to delivery of the seal, without subcontracting critical stages.
Honorarios cerrados
Budget aligned with the project's actual scope, with no surprises during the process.
Scalable in phases
Option to split the service according to the developer's needs and schedule.
A single point of contact
No salespeople or layers of intermediate management that drive up costs at major consulting firms.
This eliminates the structural overhead of a large agency and translates into rates that are 20–30% more competitive, without sacrificing expertise.
