What is building science?

Our building code is written and our buildings built substantially based on what has worked in the past. Sometimes what has worked no longer works and we end up with a problem:


Leaking buildings: A gradual evolution of design, methods and materials resulted in a systemic failure in the building industry.  So we had to change.  What used to work no longer work!


Seismic events: We had structural codes that we thought were okay but after the Canterbury Earthquake Sequence we realise that some aspects were not sufficient so we had to change.  


Building code:  A study of the development of building codes in NZ reveals that every change has been reactive.  A response to a disaster or major problem.


Building is often thought to be technical and not very scientific but everything we do with buildings has a scientific basis.

The properties and behaviour of water is called chemistry.

The forces that weather applies to a building is called physics.

The study of mould and decay is called biology.

The healthy or unhealthy interaction of people living in buildings is called health science.

So building science is just an essential part of everything we do with buildings.

Alexander and Co seek to integrate building science into everything we do so we can;

  • Accurately quantify any failure to make sure that diagnosis is not just an opinion.

  • Take guess work out of design

  • Test how your building really does perform

  • Make buildings more energy efficient.

We seek to be both quantitative and qualitative.

quantitative | ˈkwän(t)əˌtādiv | adjective relating to, measuring, or measured by the quantity of something rather than its quality: quantitative analysis.
