The document discusses an interactive workshop called Greenview that aims to help people visualize energy use through interactive interfaces. It focuses on using augmented reality tools on smartphones to reveal near real-time energy variations in university buildings. This would help quantify energy performance by defining when a building is using energy happily (lower than normal usage), neutrally (within a normal range), or sadly (higher than normal usage). Normal usage would be calculated based on energy usage over the past 12 months.

3. DE MONFORT UNIVERSITY
World-class university situated in Leicester, with more than 18,000 students and
3,000 staff, five faculties offering around 400 courses and an annual turnover in
the region: £132.5 million
INSTITUTE OF ENERGY AND SUSTAINABLE DEVELOPMENT
Leading research institute conducting innovative and groundbreaking research
into renewable energy, sustainable development and public engagement. Also
run 3 MSc courses.
INSTITUTE OF CREATIVE TECHNOLOGY
The IOCT is a unique research Institute at the intersection of Science,
Technology, Art and the Humanities

4. The invisibility of energy

5. By its nature, ‘energy’ is an abstract and
invisible force that is conceptualised or
commonly defined in a number of different
ways, for example as a commodity, as a
social necessity, as an ecological
resource, or as a strategic material.*
* Burgess & Nye (2008), Re -materialising energy use through transparent monitoring systems, Energy Policy

7. The aim? To understand the
role of ICT in reducing energy
consumption of a large scale
public building through the
design of an ICT interface
connecting building users to
their electricity consumption.

9. BEYOND INFORMATION PROVISION
•There is a need for a different approach- recognising the
complexity of user perceptions and understandings (Niemeyer,
Petts et al. 2005);
•Combining a bottom-up and top-down approach in order to
minimise mixed messages (Owens 2000);
• The value of public engagement (Burgess and Clark 2009;
Ockwell, Whitmarsh et al. 2009).
•The importance of context.

12. TRANSPARENCY
The principle idea is to reveal the level of
energy variations in near real time in
precise university building locations using
augmented reality tools on common
smartphones.

14. EMPEDIA AND AUGMENTED
REALITY
The Empedia (www.empedia.info) platform has been developed under a KTP agreement
between De Montfort and Cuttlefish Multimedia for iphone and Android platforms
It will be enhanced with an Augmented reality browser for Greenview applications

21. QUANTIFYING ENERGY
PERFORMANCE

22. QUANTIFYING ENERGY
PERFORMANCE
• What is a happy/neutral/sad building?
• What is normal consumption?
• Can we calculate energy performance?

23. WHAT IS A HAPPY BUILDING?
• When is a building happy?
• When is a building sad?
• To build into the Greenview application
– it needs to be directly calculable from ‘live’ energy consumption data
– buildings must switch between being happy and sad over time

24. EACH BUILDING HAS ITS OWN
DEFINITION OF NORMAL
• A building is happy when consumption
is lower than normal
• A building is sad when consumption is
higher than normal
• But what is normal?

25. WHAT IS NORMAL?
• A function of the latest 12 months of consumption
• So normal changes over time
• As new data are collected, older data are discarded

26. WHAT IS NORMAL?
• Consumption (and normality) is dependent on ‘time of week’

27. WHAT IS NORMAL?
• Consumption (and normality) is dependent on ‘time of week’
• Most weeks are similar but all weeks are different
Calculate percentiles from each half hourly period

28. WHAT IS A PERCENTILE?
• For a given set of observations:
[2,4,4,5,6,8,6,3,6,1,4,4,1,5,7,2,7,2,8,3,3,9,8,3]
• Arrange all the observations from lowest to highest value:
[1,1,2,2,2,3,3,3,3,4,4,4,4,5,5,6,6,6,7,7,8,8,8,9]
• The middle one (or average of the middle two) is the median:
[1,1,2,2,2,3,3,3,3,4,4,4|4,5,5,6,6,6,7,7,8,8,8,9]
• 50th percentile (or median) = (4+4)/2 = 4
• 50% of observations are above, 50% are below

29. WHAT IS NORMAL?
• Consumption (and normality) is dependent on ‘time of week’
• Most weeks are similar but all weeks are different
• It is possible to create a normal weekly profile

30. WHAT IS NORMAL?
• A normal range can be defined as the ‘middle’ 50%
• Between the 25th and 75th percentiles:
[1,1,2,2,2,3|3,3,3,4,4,4,4,5,5,6,6,6|7,7,8,8,8,9]

31. QUANTIFYING ENERGY
PERFORMANCE
• A building is happy when consumption is in the green zone
• A building is neutral when consumption is in the yellow zone
• A building is sad when consumption is in the red zone
