FAQs

Frequent
questions

What is energy consultancy for a Passivhaus project?

It is a technical service that analyses the energy, thermal and hygrothermal performance of the building, optimising design, materials and systems to meet high efficiency standards.

Do I need energy consultancy if I don't want to certify my building?

Yes. Consulting helps to reduce energy consumption, improve comfort and prevent construction defects, regardless of the certification.

What tools do you use for analysis?

PHPP for energy modelling, WUFI for hygrothermal analysis, Flixo/THERM for thermal bridges and TM59 for overheating.

Can you work with my current architect or engineer?

Yes. We join the technical team to support the design and implementation.

Do you offer on-site support?

Yes. We carry out site visits, check details and provide support with airtightness and quality strategies.

Do you operate in Latin America?

Yes, we also work in Latin America.
