December 2010: Air Conditioning Inspections Required for Systems >12kW

Since 4 January 2009, air conditioning inspections have been a legal requirement for any system with an effective rated output of 250kW or more. For systems with a rated output of 12kW or more, the first inspection must be done by 4 January 2011. Inspections must be carried out by an accredited air conditioning inspector, ILES Consulting Ltd being fully accredited. For further information see our Services section.

May 2010: Part L 2010 - It's Finally Here

Part L 2010 of the Building Regulations has recently been released with implementation in October 2010. Below is a summary of the key design implications:

1. Beating the Notional Building will be a tough challenge needing a focused and clear compliance strategy.

2. If an electric system is specified as the fuel source this will only tend to compete with the 2010 Notional Building target in highly insulated buildings. Otherwise fuel types with lower carbon intensities will have to be considered.

3. There’s less scope for the conventional ‘rescue measures’ without recourse to Renewable technologies. 2010 Part L will encourage better lower carbon intensive buildings as a fundamental pre-requisite to new building design.

4. Buildings such as Commercial Offices will require significant improvements in lighting efficiency with increased use of daylight and therefore more use of dimming and/or new lamp technologies.

5. Naturally ventilated schools although less heavily affected by % CO2 reductions than some air conditioned buildings will not pass as easily with Biomass boilers without other additional energy saving measures.

The question is how will these changes affect building design?

Reducing CO₂ by an average of 25% will be a significant challenge for the Construction Industry. Designers will need to target energy savings in all areas to meet the much more stringent Notional Building Standards.

Compliance will still be possible without the need to install renewable energy sources however it will need a combined effort by all member of the Design Team to assess and reduce energy and carbon to the required levels.

There will be greater use of DSM to maximise calculation accuracy and opportunities for passing 2010 Part L.

The improved benchmark for specific fan power will impact on plant spaces and ductwork risers such that additional space might be needed in the footprint of new buildings.
