Last week I learnt that that my full co-authored (with co-author Fred Popowich, Lyn Bartram, Bob Gill, and Ivan Bajic) paper “AMPds: A Public Dataset for Load Disaggregation and Eco-Feedback Research” was accepted at IEEE‘s Annual Electrical Power and Energy Conference (EPEC 2013). So I will be travelling to Halifax, Nova Scotia in the Canada. Here is the paper abstract:
A home-based intelligent energy conservation system needs to know what appliances (or loads) are being used in the home and when they are being used in order to provide intelligent feedback or to make intelligent decisions. This analysis task is known as load disaggregation or non-intrusive load monitoring (NILM). The datasets used for NILM research generally contain real power readings, with the data often being too coarse for more sophisticated analysis algorithms, and often covering too short a time period. We present the Almanac of Minutely Power dataset (AMPds) for load disaggregation research; it contains one year of data that includes 11 measurements at one minute intervals for 21 sub-meters. AMPds also includes natural gas and water consumption data. Finally, we use AMPds to present findings from our own load disaggregation algorithm to show that current, rather than real power, is a more effective measure for NILM.

The dataset (and paper) can be found at http://ampds.org.
I just learnt that that my full co-authored (with co-author Fred Popowich, TaeJin Moon, and Bob Gill) paper “Inspiring Energy Conservation Through Open Source Power Monitoring and In-Home Display” was accepted at the IEEE Power and Energy Society General Meeting. It will be held in Vancouver so I will not need to travel! Here is the paper abstract:
Many homeowners and occupants are interested in energy conservation for economical and/or ecological reasons. A number of commercial energy conservation solutions exist on the market today. However, these products contain closed systems and do not provide easy access to much of the raw data needed for more sophisticated analysis. An open source solution would be a great benefit for homeowners and occupants, allowing access to (and custom analysis of) raw power readings. We present a complete open source solution that monitors power, stores raw power readings, and makes provision for an in-home display, that informs stakeholders about energy consumption through a real-time ambient feedback effectively becoming an eco-feedback device.
Keywords: Power Monitoring, In-Home Display, Residential, Open Source, Arduino, RS-485, Modbus, Electric Imp, Energy Conservation
Apparently there were over 1,600 submission and they will be accepting only between 60-80 papers. Those are some odds!
- The Cognitive Power Meter: Looking Beyond the Smart Meter (eco-sustain.org)
Last week I learnt that that my full co-authored (with co-author Fred Popowich and Bob Gill) paper “The Cognitive Power Meter: Looking Beyond the Smart Meter” was accepted at IEEE‘s 2013 Canadian Conference on Electrical and Computer Engineering (CCECE’13). So I will be travelling to Regina, Saskatchewan in the Canada. Here is the paper abstract:
The smart meter is often heralded as the key component supporting energy displays that can notify home occupants of their energy usage. But, a smart meter is only a digital power meter with enhanced communications capabilities — it is not actually smart. We need to look beyond the smart meter and define what intelligence is needed to actually make a meter smart. One area with promise is load disaggregation. Load disaggregation can be used to determine what loads contributing to the consumption reading at the smart meter. A smart meter incorporating load disaggregation intelligence can be seen as going beyond the traditional smart meter — what we call a cognitive power meter (c-meter). However, using load disaggregation, in its current form, is not feasible. We critically review the requirements for a c-meter and provide insights as to how load disaggregation research needs to change to make the c-meters a reality.

I have been working very hard on my Depth Exam lately and have not had a chance to post much. Until today, when I decided that I wanted to publicly make available a 2010 dataset of a monitored home for use in research on load disaggregation, NILM (non-intrusinve load monitoring or NIALM), Smart Homes, and AAL (ambient assisted living).
This dataset contains ION6200 power meter and Digi Wall Router ambient light/temperature sensors readings; including weather and daylight data. Sensor readings were collected over a ZigBee wireless network at 15 minute intervals. The following published papers used this dataset: 2011hoa and hoa2012.
You can get this and future datasets from here: https://github.com/smakonin/HomeData

So I have finally had a chance to update the My Smart Home: Consumption Report to reflect readings from the new DENT PowerScout 18 meters and a new database design. Checkout:

Earlier this month I learnt that I (and co-author Fred Popowich) will have my first journal paper published in the GSTF Journal on Computing in the April/2012 edition (vol 2, no 1). Here is the paper abstract:
Smart homes of the future will have a number of different types of sensors. What types of sensors and how they will be used depends on the behaviour needed from the smart home. Using the sensors to automatically determine if a home is occupied can lead to a wide range of benefits. For example, it could trigger a change in the thermostat setting to save money, or even a change in security monitoring systems. Our prototype Home Occupancy Agent (HOA), which we present in this paper, uses a rule based system that monitors power consumption from meters and ambient light sensor readings in order to determine occupancy. The agent is also able to determine when the occupants are asleep, and thus provide the potential for further energy saving opportunities.
Keep your eyes peeled as there are a number of other submissions that I am either waiting on review or in the midst of writing. Write on…
- The Affect of Lifestyle Factors on Eco-Visualization Design (eco-sustain.org)
On Monday I learnt that my full co-authored (with Maryam H Kashani and Lyn Bartram) paper “The Affect of Lifestyle Factors on Eco-Visualization Design” was accepted at Computer Graphics International (CGI 2012). So I will be travelling to Bournemouth University in the UK. Here is the paper abstract:
As people become more concerned with the need to conserve their power consumption we need to find ways to inform them of how electricity is being consumed within the home. There are a number of devices that have been designed using different forms, sizes, and technologies. We are interested in large ambient displays that can be read at a glance and from a distance as informative art. However, from these objectives come a number of questions that need to be explored and answered. To what degree might lifestyle factors influence the design of eco-visualizations? To answer this we need to ask how people with varying lifestyle factors perceive the utility of such devices and their placement within a home. We explore these questions by creating four ambient display prototypes. We take our prototypes and subject them to a user study to gain insight as to the questions posed above. This paper discusses our prototypes in detail and the results and findings of our user study.
Keywords: eco-visualization, informative art, ambient display, power consumption, energy conservation, sustainability.
CGI 2012 received 178 papers, 111 were rejected, 35 were selected for the CGI 2012 Special Issue of The Visual Computer, 32 were selected for the Electronic Proceedings.
I will be updating the Elements of Consumption (EoC) project page soon. I plan to be releasing the project source code as an open source project along with details on how to create your own custom ambient display.
Over the weekend I was busy replacing my 2 INO6200 meters with 2 DENT PowerScout 18 branch circuit power meters (BCPM). Instead on only monitoring 2 circuits (the main house and the heat pump), I can now monitor 24 different circuits!
I will post a link to a real-time consumption report soon. I am having issue with my ModbusTCP server and a lack of time to program the report.
I have been busy getting back in to course work for this fall; but I though it would be good to set up a poll to see what people think about what will drive energy conservation. Please contribute by taking my poll.

Today I finally installed my Proliphix IMT550w Network Thermostat. As you may have read in my earlier post, it was hard to find the right thermostat for my American Standard HVAC system, and it took me over 2 week to do an exhaustive search to find the IMT550. To review, I have a dual fuel system with a 2-stage heat pump and a 2-stage, variable speed gas furnace.
I spent the last couple of weeks figuring out how my HVAC system is wired. This took some time because there where a different amount of terminals with different labels (e.g. my system labels W2 as X2, and not needed). The colouring of the wires was also different. I cautiously documented the current wiring scheme and the new wiring scheme with my new IMT550w installed. I then talked to Proliphix Support and they worked with me to come up with the right wiring scheme. Proliphix has one of the best support departments. Mark, from Proliphix Support, was knowledgeable and responded quickly to all my emails–what more could I ask for. For those of you who are interested in seeing the before and after diagram of my HVAC wiring take a look at my HVAC Wiring Scheme document.
What I like about the IMT550w is:
- I can read and change setting from my browser, making it easier to set up schedules;
- I can install additional indoor temperature sensors, providing more comfort and energy efficiency;
- the temperature sensors that go with the thermostat (need to order separately) are more accurate than the ACONT802;
- the thermostat firmware can be updated with new functionality.
