How to measure carbon
CIBSE is the standard setter and the authority on building services engineering. It publishes guidance and codes which are internationally recognised as authoritative, and sets the criteria for best practice in the profession. The first benchmarking paper issued by government was the ECG19 (Energy Consumption Guide.) The benchmark set in the guide was 234kW/m2
for an office
building. In TM46, it has been decided by the CLG that the same building became
95kW/m2 , which meant that a previous D
rating suddenly became a G. This has become the benchmark in the
DEC, although the calculation is much more complicated.
The CIBSE Guide F is the key guide used
by CIBSE Low Carbon Consultants, and it sets out the engineer’s approach to lower energy input. So how can FMs use these guidelines in
practice? Well, if you can’t measure it, you can’t manage it. A good starting point would be to look at your current energy bills. Monitoring your bills will give you a good understanding as to what your usage is and whether this has increased over time. The next step would be to move onto metering which will monitor your energy usage 24/7. Finally, sub- metering will give specific readings on a specific area, for example different floors in a building or specific plant. Once energy readings have been
evaluated, FMs can start to focus on solutions. For example, lighting can save up to 40% if replaced by a suitable low- energy lighting scheme. Off-the-shelf techniques and easy wins
are: • Manage your energy usage – if you don’t need it, turn it off; • Low energy lighting with PIR and BMS controls will help save significantly; • Voltage Optimisation systems reduce the
Alongside engineers, FMs will be crucial to reducing the country’s energy and therefore will play a big in the future of the planet’s environment.
voltage and clean up power – this can give approx 7% reduction; • Inverter drives – saves on overdesign and optimises energy; • Upgrade old air conditioning systems to reverse-cycle heat pumps – they can be more economical to run than your boiler and meet the F Gas regs; • Biomass – this system is well worth considering for industries that have more space, such as schools and manufacturing plants; • BMS rescheduling – to monitor the BMS and re-programme for intelligent optimisation or, if you haven’t got a BMS, install one; • CHP is an efficient way to use fossil fuel. The technology involves the simultaneous generation of useable heat and power in a single process; • PV Cells (Photovoltaics) use solar power to generate electricity;
• Solar thermal – DHW – solar heating of hand washing.
Is the future green?
Energy companies have indicated that by 2020 they will be moving into greener technologies. As of 2008, approximately 37% of the power giants’ generation was coal fired. They are looking to change coal to gas, which means that by 2016 they have a target to reduce this to 28% and
