  1. Greening Business: An online teaching resource Session 5: Utilities management – energy and water Suggested activities

  2. Activity 1: Energy savings • Your organisation has decreased its grid electricity use from 13,043,000 kWh in 2003 to 12,987,000 kWh in 2008 over 5 years. • At an average cost of £0.10 p/kWh what are the financial savings in 2008 compared to 2003? • 1 kWh grid electricity = 0.537 kg CO2 What are the CO2 savings in 2008 compared to 2003?

  3. Activity 2: Energy awareness campaign • You are in charge of developing an energy awareness campaign at your University • Outline how you will encourage staff within the University to reduce their energy through your campaign • Outline how you will encourage students within the University to reduce their energy through your campaign

  4. Activity 3: Generating your own energy • Research an alternative energy source choosing from the following: • Solar (thermal and photovoltaic) • Wind • Hydro • Biomass • Geothermal • Outline the advantages and disadvantages of the renewable energy source • What is the potential for this energy source at the institution at which you are studying? • As a class, compare and contrast your findings of different renewable energy sources and their applications

  5. Activity 4: Energy audit • Carry out a simple energy audit (or baseline environmental review) of one of the buildings that you regularly use on the campus • List five strategies that can be put in place to improve the energy criteria in the building • What are the approximate costs and payback periods of these measures?

  6. Activity 5: Rainwater harvesting case studies • Look at the case studies at: http://www.rainharvesting.co.uk/pages/case_studs/cs_studs_lst1.html • Make a table summarising the use, annual rainfall, roof area, rainwater collection yield, capital cost • Calculate the annual savings (based on water rates of: £1.4 per m3) • How long will the financial payback time of the system be?

  7. Activity 6: Water audit • Carry out a simple water audit (or baseline environmental review) of one of the buildings that you regularly use on the campus • List five strategies that can be put in place to improve efficiency of water usage in the building • What are the approximate costs and payback periods of these measures?
