31/10/2013: New house air permeability test passed wth flying colours

Part L of the Building Regulations sets the energy efficiency standards for new homes and requires that a sample of new homes on all developments is tested for air leakage (also known as air tightness, air permeability or air pressure testing).

With everyone's focus being very much on home running costs and energy conservation these days, we went to great lengths to not only meet but to exceed all the energy standards called for in the Building Regulations Section L1A, dealing with fuel and power conservation in new dwellings.

With the final test being the air permeability test, carried out this week, we are proud to say that our efforts were a great success. The regulations stipulate that there must be no more air flow measured than 10m3/(h.m2). The new house showed an air permeability of just 3.5m3/(h.m2), giving a great boost to overall energy efficiency.

The final stage of preparing the house for occupation is commissioning the new high efficiency boiler, which is scheduled for Monday.

It's only the boss, just step over him.

One school of thought holds that your importance in an organisation is inversely proportional to the length of time you could lay dead on your office floor before anyone noticed any effect on the business.

The idea is that as you become more valuable, your role evolves to become more strategic and long term. The organisation should be self-managing to an extent in the shorter term.

With Craig in America for three weeks, it is slightly less dramatic, but nonetheless a good test of the theory. With the team that has built up at CWN over the years, current projects are all moving along nicely. For longer term ideas, please bear with us for a short while.
