Q253
- Did not get eh question because he was ranking question as if it was about his own usage and not objectively with the 10 min usage time frame
Q868 / 869 Cost of electricity
- Gave an answer about when people used the most rather than how much it costs the utility to provide electricity
- Realized that his answer to the last question was the one to this question “I guess it’s a similar one”
Q321/828/257
- Did not really understand what the units of electrical energy were
- Did not understand what power rating means
- Did not know that you pay a certain price for each kWh used
- Tried to clarify to him that the concept was similar to filling up a tank of gas and that you pay an amount per gallon that you fill up
- “I use about $100 a month, I don’t get if this question is asking about an hour”
Q873 Ranking questions
- 72-69 would not be energy saving action if this was done in the summer
Q304 IHD Intro
- Don’t know why you had to turn on and off the appliances and didn’t get it was referring to the simulation on the next page
- Understood that the scenario was talking about the Smith’s family but didn’t get the description on the bottom paragraph. “What do I turn on and off and where do I do these actions?”
Q924 IHD simulation
- Did not know he needed to turn on and off each appliance
- Instead of turning on and off appliances to learn about usage in general, he only turned on the appliances he had in his own home
- Clicked reset all in the middle and then once the simulation reloaded he decided to click next
Q296 Electricity knowledge 10% reduction
- Just reiterated the energy saving ranking question statements
- Did not use any of the information from the simulation nor was he even thinking about the Smith’s family
- 10% reduction for him was not about the Smith’s electricity budget, but rather his own
Q873 Energy savings ranking
- Did not seem to realize that we asked this question before and used the same strategies when he was thinking out loud
- Idea: we can try to make the energy saving ranking questions so that they reflect the same appliances that is displayed on the IHD simulation
Q872 Cost of a kWh
- “Since the smith’s pay around an avrg of $150, so maybe the cost of a kWh is $150”
Q300 General Suggestions
- “I don’t understand this question, is it asking whether we want to add pictures to the simulation?”
- Suggested that we have a picture of a house and the simulation shows where in the house energy is used the most
Q352 Helpfulness
- Good that you can find out which appliance uses the most and I can go to best buy to get new appliances
- It would be very helpful because I can see which parts of my house is using the most electricity
- Based his answers on the feature he presented in the general suggestions question
Q363 Reduction
- Ball park guess
Q410 Predicted Reduction by In-Home Displays
- Thought the most important information was kWh
- Did not understand instantaneous cost of electricity
- Thought the least helpful information was combination of feedback
- When asked to re-iterate he just replied I don’t think some of the other information would be useful
Q359 WTP
- Came up with this price by comparing the cost of installing an ADT security system at home
- He explained it would probably require the same amount of effort by a company to install something like this
- He said if there was a warrantee, he’d be willing to pay $50
Q874 Expected Savings
- $10 month
- Now he used an expected savings assuming his bill was $150 like the smith’s house
Note: need to remove back button from boilerpoint questions before launch Hypothesis guess: the aim is to reduce coal and pollution, and to help people find ways to reduce electricity
