cube of the speed it is set at. SERIES 18 | MODULE 03 | SEPTEMBER 2020 SERIES 17 SMART GRIDS
Question 2. Does it make sense to cut the energy manager role to be part-time? □ Yes, the Energy Manager role is largely administrative. □ No, a part time Energy Manager will be forced to prioritise compliance and reporting activities, leaving them little to no time for proactive energy management.
QUESTIONS
□ No, let’s instead cut the rate of pay. □ No, let’s instead have the role cover: water/waste/ sustainability/HSE.
Question 3. Why is it a false economy not to pay a competitive salary for energy roles? □ There is a competitive market for good energy professionals who can actually deliver savings.
■ 1940s ■ 1930s ■ 1960s
□ Offering a weak salary risks recruitment and retention issues for strong candidates.
□ All of the above. SPACE HEATING
□ Unfortunately, enhanced control is prohibitively expensive to implement.
ENTRY FORM
□ Doubling the speed of a fan or pump increases energy consumption by eight times. Conversely, a 50% speed reduction delivers a ~90% energy saving.

□ Fans and pumps are significant energy users, e.g. in heating and ventilation systems.

Please complete your details below in block capitals
Please complete your details below in block capitals □ All of the above.
Please complete your details below in block capitals.
□ The cost of inaction is not nothing: if the organisation does not invest in an energy team, then a small uplift in the unmanaged energy bill of just 2.8% would end up costing the same as the staff costs outlined in this scenario.
■ Vehicle to Grid enabling EV batteries to discharge to the grid to ‘smooth’ high electricity peak demand profiles.
■ A temperature sensitive switch ■ A temperature sensor ■ A proportional control device ■ A digital display device

Question 7. How can lifecycle costing help save energy? □ Operational energy costs are significant over the lifetime of a project.
□ Examining capital costs alone can often be misleading, since capital costs are often lowest for less efficient equipment that ends up being very expensive to run.
■ Facilitate the connection of distributed renewable generation and variable loads such as electric vehicles and heat pumps
