This document discusses improving energy efficiency in community buildings in northern territories. It provides examples of how insulating buildings, installing efficient appliances and lighting, and implementing behavioral changes can significantly reduce energy usage and costs. Specific strategies mentioned include adding roof insulation, sealing air leaks, installing heat recovery ventilation, and switching to more efficient heating sources like heat pumps. Case studies show potential savings of 10-20% from insulation, 10-15% from sealing, and up to 80% reduction in lighting costs from LED bulbs. Overall, the document encourages analyzing current energy usage and exploring options to lower demand and choose renewable energy sources.

Is there potential in energy efficiency? YES, it is!
6. Renewable Community Empowerment in Northern Territories
Energy use in a typical community building
Space heating
70%
Water heating
5%
Lighting
15%
Other electrical
appliances
10% Every building is different, so find out
about your specific energy demand
(see next slides)
But in general accounts space
heating for the vast majority of
energy use.
7. Renewable Community Empowerment in Northern Territories
How much energy do you use today?
Find out what type of energy you use (all of it: oil, gas, electricity, wood etc.)
Look at records of energy use: energy meter readings and bills, at least three
years back to balance for warmer and colder years
Monitor your energy use. Look at how, when and by whom the building is
used. Find out about peaks and troughs in energy use over the year.
Ask for your help from your energy provider, specifically if you have electric
heating, to get access to detailed data about your energy use.
Write your data down in a table.

Where to start? 1. Reducing Heat Loss
Additional insulation
Increased air-tightness
Effective heat recovery ventilation
2. Efficient Use of Energy
Energy-efficient electrical appliances & ventilation
Energy-efficient lightning
Managing consumption & controlling
3. Choosing Energy Source
Heat pump
Biofuel
Solar heating or Solar Power
3. Choosing Energy
Source
2. Efficient Use of
Energy
1. Reduce demand &
Reducing Heat Loss
9. Renewable Community Empowerment in Northern Territories
How to do it?
1. Behaviour change, e.g.
Switch off lightning and electrical appliances when not in use
Close doors and windows
Report leaking taps
2. Physical improvements, e.g.
Insulation (roof, sealing gaps around windows, doors)
Space and water heating (new boiler, heating controls)
Lighting (Slim-line T5 tubes or LED)
Water saving devices to taps, dual-flush toilets
3. Choosing Energy Source, e.g.
Solar heating
Bioenergy
10. Renewable Community Empowerment in Northern Territories
How much to save? Some Examples
1. Behaviour change ca 10%
2. Physical improvements, e.g.
Roof insulation ca 10-20% of space heating energy
Sealing gaps around windows & doors ca 10-15%
Replace old T8 tubes with LED up to 80% of lightning
electricity
3. Choosing Energy Source
Depends very much on the specific situation
