architecte certifie "PassivHaus"



Architecture (Latin architectura, from the Greek ἀρχιτέκτων – arkhitekton, from ἀρχι- “chief” and τέκτων “builder, carpenter, mason”) is both the process and product of planning, designing and construction.

The art of architecture has always been a social art. Whether it is about reinforcing the prestige of rulers,

or creating spaces which people can appropriate, it is the same. The goals may be different,

but architecture, uniquely in the arts, only has life when people start to appropriate and inhabit the

“thing”, that has been built. Outside of major financial centres and the Middle East,  architecture has

always been about adaptation to climate, and more importantly about the social structure of the place.

This means that “architecture” is always bespoke. There is NO one size fits all.

In the face of climate instability, and government pressure, architecture is changing again. U

Unlike the glory days of the modern movement, energy has become the key issue in designing and


– How much energy does it cost to make and transport the materials you use?

– How much energy is the building going to consume or contribute once built?

– What kind of pollution is created by the elements used in the construction?

– How long is the building going to last?

– How much is it going to cost to demolish it, and dispose of or recycle the rubble?

These issues are the subject of government debate the world over.

My response as a responsible architect cosnists of the following:

– Training: I am a Certified PassivHaus designer. I have also followed a training course in HQE (equivalent LEEDS)

-Research. The fundamental problem with buildings is their their thermal lag. It might seem cheap to build light structures, but with little or no thermal inertia, you end up paying twice for heating.

I am totally modernist in my approach to design. To balance this, I also undestand the advantages of traditional construction elements, and seek to use this traditional knowledge in my projects.

New construction processes have not reinvented the wheel. In our capitalist system, they have reinvented the parameters:

– Building cheap is good for the investor.

WHY? Because accountancy takes capital cost into account and not life cycle costing. For a buyer, it’s as

if  sales are on permanently.

– Building cheap is bad for the user.

If the user is on benefits, he or she is happy to have a home. When the energy bills come in it is a different story.

If the buyer is financially secure, sooner or later, he will realise he is paying a king’s ransom to keep his building warm. And he will ask questions.


Build smart; low or zero energy construction is more expensive in terms of capital outlay ( around 12%)

BUT over 15 years, it represents substantial savings in terms of fixed costs even on the basis of constant fossil fuel and electricity prices.
