1.

Reduce the need for different 'fuels': Reduce the amount of bulbs in an area, turn down or off the heating in areas that aren't in use, using timer controls to make sure the heating is only used when it is needed. 

2.

Make the most of what you already have: Use natural light, shutting the blinds/curtains when it is cold to act and an extra insulator, maintain heating system by bleeding the radiators and keeping it well serviced.

3.

Encourage behavior change from users: help users to understand how to use the heating, lighting and electrical appliances in the building effectively. Use posters, nudge behaviours, information on costs, training sessions and holding public energy awareness days.

4.

Panning for future improvements or upgrades: Many community buildings have poor insulation, traditional lighting and inefficient heating systems, largely due to their age. The costs of replacing and upgrading these aspects of a building can vary significantly, but most energy efficiency measures will eventually pay for themselves through the saving they generate from the building’s reduced energy bills. A professional energy audit can help you understand what you have and how energy is being used to help you to identify the most effective options for energy efficiency improvements.
