Passive House

Passive House is not an energy standard but a fundamental building concept where the primary goals are to achieve superior energy efficiency and occupant comfort.

Passive house is an enclosure first “passive” approach

 It encompasses all aspects of high energy performance, sustainability and resiliency that can be applied all types of buildings, in all types of climates.

 

A Passive House is a building, for which thermal comfort (ISO 7730) can be
achieved solely by post-heating or post-cooling of the fresh air mass, which is required to achieve sufficient indoor air quality conditions – without the need for additional recirculation of air.

The 7 strengths of stone

Explore the strengths of stone

01

Fire resilience

Withstand temperatures above 1000°C.

In land-scarce urban areas, more and more people are working and making their homes in high-rise buildings. These structures can be brilliant solutions to the challenge of safely housing a growing population.

02

Thermal properties

Save energy by maintaining optimum indoor temperature and climate.

It makes living and working conditions more healthy and comfortable, helping people to thrive, especially in urban environments. Temperature maintenance can dramatically reduce heating, cooling, and ventilation costs, and reduce a building’s carbon footprint.

03

Acoustic capabilities

Block, absorb or enhance sounds.

From railways to tramways, roads to airports, good infrastructure is crucial to urban life, which can be very noisy. The resulting ground-borne vibration, traffic noise – and not to mention human noise pollution – all have a serious and negative impact on our wellbeing, especially in densely populated areas.

04

Robustness

Increased performance and greater stability with lower costs.

In land-scarce urban areas, more and more people are working and making their homes in high-rise buildings. These structures can be brilliant solutions to the challenge of safely housing a growing population.

05

Aesthetics

Match performance with aesthetics.

When people live and work in aesthetic spaces, they feel comfortable and motivated. Environments in which people enjoy spending time can improve social cohesion and make neighborhoods safer and healthier.

06

Water properties

Manage our most precious resource.

A growing population puts traditional food production under pressure, and climate change has increased the need for flood defenses. Stone wool can be engineered to absorb or repel water as needed, as well as recirculate it in a greenhouse, solving a range of water management problems.

07

Circularity

Reusable and recyclable materials.

Rock is one of the most abundant raw materials on the planet, but we still need to make better use of our planet’s resources. We have developed our technology in a way that allows us to use waste from other industries as alternative raw material.
