Questions
Passive House, Passivhaus in the original German, is a measurable building standard, not a style or a marketing label. It was defined by the Passive House Institute (PHI) in Germany, and it sets strict targets for how little energy a home needs to stay comfortable. The building itself does the work: a continuously insulated, airtight envelope, high-performance windows, almost no thermal bridges, and mechanical ventilation with heat recovery that keeps constant fresh, filtered air moving without wasting energy.
The result is a home that holds a stable, comfortable temperature year-round on very little energy, is quiet, draught-free and healthy to breathe in. In Portugal the standard earns its keep in summer as much as winter: the same envelope that retains warmth in January keeps the heat out through the hottest months.
And it's verifiable. A true Passive House is proven by measurement: most importantly a blower-door test confirming the envelope leaks no more than the framework allows. That's the level of proof we design and build our homes to meet.
Solar panels generate clean electricity during the day. The battery stores what you do not use immediately, so it is available later — in the evening, or during grid interruptions.
V2H allows a compatible electric vehicle to send stored energy back to the home, adding an extra layer of resilience and flexibility to the household energy system.
Homes are designed to support smarter local energy management, sharing insights and balancing demand across the development to reduce reliance on the external grid where possible.
The House Agent is the home's digital layer. It helps you understand performance, manage comfort and energy, and supports future-ready upgrades as technology evolves.
