1 Invest in your building fabric.
It is vital to improve U values, lower air tightness and design to enhance solar gain. This approach can achieve compliance with Part L, whilst lowering heat demand and achieving as many credits as possible under Ene 1 and 2.
2 Energy Display Devices.
Whilst costly (some retail around £400), this could be a relatively easy way to win heavily weighted credits. Provided a device can monitor and display electricity and primary heating fuel consumption, two credits can be awarded.
3 Ene 5.
In order to award 1 credit under the new guidance any white goods offered for purchase now need to be compliant with the CSH criteria. It is best to source suppliers of energy efficient white goods to avoid losing this heavily weighted credit.
4 Use a Microgeneration Certificate Scheme (MCS) accredited installer.
If you are using renewable technology, this will ensure you have the chance to gain credits under Ene 7.
5 Check if your material suppliers can provide you with Chain of Custody Certificates.
To help you gain credits under Mat 2 and 3, more and more suppliers are able to supply the likes of Forestry Stewardship Council (FSC) and Environmental Management System (EMS) certificates, which will help you gain free credits, ensuring you can keep costs down on your Code for Sustainable Homes assessment. If you use the same suppliers on all your developments then you’ll only need to provide this evidence to us once, reducing the amount of time you’ll need to spend on future CSH assessments.
6 Ensure drainage design and calculations are completed.
At a very early stage in the project make sure drainage design and calculations are completed. With the mandatory requirement under Sur1, it is even more important to ensure the drainage system is compliant, and avoid any unforeseen (and potentially very costly) issues further down the line.
7 Ensure your site waste management plan is in place.
Before work begins on site, ensure your site waste management plan is in place and that you can divert 85% of non-hazardous waste from landfill. This will ensure you achieve maximum credits in this category.
8 Remember to meter and monitor energy and water consumption on site.
Credits are available under Man 3 here, and provided resources are available to keep track of energy and water consumption and display this information graphically, these can be low cost credits.
9 Appoint a suitably qualified Ecologist.
Before you begin work on site appoint a suitably qualified Ecologist. The ecology credits are heavily weighted and can be very straightforward to achieve.
10 Register with Considerate Constructors Scheme (CCS)
Vital credits can be gained for achieving CCS certification, BUT you must register with a considerate contractors scheme (or similar) before work on site begins.
