Energy is wasted in many areas

Often energy is wasted in areas that you donโ€™t realise. If we think of a typical office building, energy is used in heating, cooling, ventilation, lighting, computers, monitors, printers, kitchen equipment and anything else that is plugged in. The easiest and perhaps most affective method to assess where energy is used in your building is to perform an energy walk round. As the name suggests, this involves walking around the building. Something you have probably done a number of times! This time however, you will possess a new understanding and knowledge of what to look out for. The aim here is to identify bad practice, inefficient equipment and poor energy habits. With the aid of a simple checklist found here, you will be able to identify wasteful energy use, opportunities for savings and maintenance issues that need addressing.

Calculate energy use at night

A great way of assessing wasteful energy use is to see how much is used out of working hours. If you take a meter reading at the end of the day and then again the next morning, the difference is the energy used whilst the building is empty. There will obviously be some energy used, a fridge and/or a security system may be in place. To bring some perspective, an average refrigerator operates at 160 Watts. Say between first checking the meter in the evening and rechecking the following morning 12 hours has passed then 160*12/1000 = 1.92 kWh of electricity has been used. Depending on what else you have on in your building, if you calculate an electricity usage significantly greater than this, then energy may be being wasted.

The walk round

Using the checklist (provided) or another of your own creation assess the entire business or site to get a record of how things currently are. Noting where you think energy is being wasted.

Report your findings and follow up with an action plan. It is more than likely that this report will refer solely to occupants behaviour. If the report is detailed, outlining why the measures are proposed then staff with be stimulated into action.

Following up

Subsequent walk rounds may focus on priority areas identified in the first. They could also reassess the situation after some energy measures have been implemented.
