Arkhi Zero Services

At Arkhi Zero, we partner with our clients to create buildings that are not just spaces to inhabit but are active contributors to a cooler, more sustainable planet.

What we can do for you?

Our PHPP service is the backbone of our sustainable design philosophy. This comprehensive tool allows us to predict the energy efficiency of your project with precision, ensuring that every aspect of the design contributes to a minimal environmental footprint.

PHPP (Passive House Design Package)

Leveraging Design PH/BIM, we craft your project in a virtual environment, allowing for unparalleled precision in sustainable and architectural design.

This approach not only enhances design quality but also streamlines the construction process.

Airtightness is crucial for energy efficiency and indoor air quality. Our airtightness modelling predicts how well your building will perform, identifying potential leaks and proposing solutions to ensure your space is comfortable, healthy, and cost-effective to heat and cool.

Airtightness Modelling

Arkhi Zero can guide your project to achieve Passive House Certification, a globally recognized standard for energy efficiency. This certification not only signifies your commitment to environmental stewardship but also enhances the value and performance of your property.

Passive House Certification

What sets us apart?

Passive House Vs EnerPHit

What does it all actually mean?

Passive House is a rigorous, voluntary standard for energy efficiency in a building, resulting in ultra-low energy buildings that require little energy for heating or cooling, creating a highly comfortable and sustainable living environment.

Passive House

EnerPHit is a certification standard for the energy retrofit of existing buildings, ensuring they meet high energy efficiency and comfort levels similar to new Passive House constructions, making older structures more sustainable and comfortable to live in.
