Problem
• Supply of important basic amenities is
costly
• Provision of energy particularly expensive
(diesel generators)
• Mining camp of 1,500 housing units:
> $1.7 million/year just for energy
• Emissions: > 10,000 metric tons of CO2

6.
Problem
• Residents don’t pay themselves: lot of
wastage
• Keep rooms cooled at 18°C for whole day
just to make sure it’s cold on return
(outside > 40°C)
• TVs are not turned off

7.
Reduce Wastage by Automation
Monitor energy Intelligently control
consumption and appliances to reduce
environment wastage
Markus Lanthaler – Graz University of Technology
8.
Requirements
• Reuse existing infrastructure
(brownfield project)
• Keep installation simple (and thus cheap)
• Remote control and maintenance
• Do not interfere with the
resident’s interests

Field Trial Evaluation
• Deployed in a remote housing site in
Karratha, Western Australia
• Run from April 2011 till November 2011
• Used simple heuristics
– resident at work: set A/C to 30°C
– cool room down before resident comes back

Conclusions
• Achieved substantial savings
• Reduced consumption by roughly 50%
– $500,000/year
– 1,000-3,000 metric tons CO2
