Follow Up Thought for Friday’s Summer Cooling Tips.

DeeDee and I started outside. The info from the back deck did not make the cut and I let it slide when i did the blog summary of her story.  So …

Shade Works

This is an Infrared image on one of my first new homes.  The 2 foot cantilever bay clearly shows the effect of the shade. There is a 20° F difference in the temperature between shaded and unshaded areas of the wall. The high temperatures on the side of the house are in the area of 128° F.  It is 97° F when I took this one.

Shade works.  Building a new home with a south facing set of large windows. It is worth your money to have a deck with a roof, or pergola over it. If you have an existing home, the Pergola is a great idea.

Concepts like this have been recommending in my Home Energy Audits.

My Nest Labs Thermostat – Week 1 Ends

 

 Last Saturday, I installed my new Nest Thermostat. You can read how that went   at http://bit.ly/yNhq3x .  It is billed as a “Learning Thermostat’, so I promised to let you know how the first week went.

Saturday and Sunday we just watched, as related in the previous link. On Monday night, we noticed the schedule had been filled in to some extent. The Nest was learning from our use over the weekend.

 

 

From the web interface here is the schedule the Nest thought we were following after two days of use.

Here is the schedule after I tweaked it a little. I filled in a few blanks and evened out some times.

My wife is somewhat more comfortable with the system.  She is checking it on her phone and even showing it to her friends. Last night she told me the wall unit is displaying some type of message. When I checked it today, the message said learning at home had started “Push Continue”. The next message said “Ready to Learn Away Schedule”, I pushed and the Nest will do it’s thing.  I’ll have to check regularly to see what it does next.

What have I learned so far?  The iPad or the Web Interface is the easiest for me to use to set and view the schedule. The phone is very handy to check the setting, to watch the outside temperature and to keep an eye on things.  On the smaller screen of the phone, turn from portrait to landscape view to see additional controls other than just temperature settings.  Under Settings – Technical, it will give you a reading of the interior Relative Humidity Level.

Monday through Thursday, we watched the settings change as scheduled.  The Nest was learning the settings for its ‘Away’ function.  Two times this week we have come home and found the Away setting triggered.  My wife is on my case. I need more info about exactly what that away function is.  I have the idea it should be like a vacation mode.  I am beginning to think it is more of a ‘not at home for a while’ mode. After reading a few other posts, I am wondering if it has to do with the function that turns the wall unit on, when you approach it?

Got up early Saturday morning.  I thought Tori might knock on the door selling those Wonderful Girl Scout Cookies! This is the weekend that Girl Scout Cookies can be sold! Headed out the door to see my dad and head for Woodturning Club.  Checked the Nest on the iPhone.  It is in away mode again!  So just 2 clicks and the temperature is set where I expected it.  LOML is still having a slow start Saturday.  Especially nice after her Fast Start Friday!  About 10:00 am from Turning Club, I checked the Nest and the temperature is up a degree.  LOML is up and around.

I just listened to the video on the Nest Site about the Learning Mode.  Away is when the Nest thinks the home is unoccupied.  During set up, you were asked to put in a Hi and a Lo.  So that is what is being used.

Following up on the video, I looked at the actual Nest!  The video went through doing everything from the thermostat, not from a remote device.  There are some differences in the interface, the ease of use was amazing.  You either turn the dial either way, or you push to click.  No double clicks.  The turning is not all that sensitive.  I actually under turned for a couple of tries. This is where you can change the Away Settings, not from a remote device. Right is a shot of the Nest with one click showing the menu.

 

 

One of the sub menus under Settings is Energy.  Here are two different shots of the Nest under the Energy Tab.

Sunday Morning, we were at church and the Nest went into away mode.  Nice to be able to control this on the phone.  The other blip was Sunday afternoon, the Nest lost the Wifi Connection. I ended up resetting the router. Nice to watch the Nest work as a regular non-Wifi thermostat also.

This is a thermostat that one week after installation, could be left with a parent living alone and a diagnosis of Alzheimer’s Disease. In this case they could still run the ‘stat’ and see what they were doing.  You could observe from a distance, if you hooked up the wifi connection. Your parent could also control their thermostat. Here is the schedule that has been set from the tweaked schedule shown earlier. (These three images are from Laptop Screen Shots.) Also an image of the schedule on the iPhone.

 

I still like this item!  It is learning! It is easy to see the schedule on multiple interfaces.  It is not the small buttons with clumsy fingers, or a screen that is hard to read.  It is fairly intuitive.  If you do Time Share vacations, and come across one, it will not be a problem.

I have a few further thoughts on improvements, but those will wait and see if I can find some others. It also makes for another post.

And last but far from least, my neighbor Tori will get here!  I will get some Girl Scout Cookies.  Then I can show her my Nest Thermostat!

The Unglamorous Conservationist

This article is a Guest Posting. I read this yesterday and thought it was very timely and appropriate with our current heat wave!

Going green is trendy. Everyone is doing it. ‘Green collared’ jobs are the way of the future. Even oil companies are spending millions to convince us that they are green at heart. So we should all jump on the bandwagon, right?

Right.

But Scott’s post last Friday (Pruis vs. Home Energy Retrofit) brings to light an important issue – the best ways to go green are not necessarily the sexiest ways. Sure it is cool to drive around in a shiny, sleek new hybrid vehicle, but if you haven’t done the basics around your house it just doesn’t make sense. Which brings me to the unfortunate paradox when it comes to energy and water efficiency…

Even though it is fashionable to be environmentally friendly, some of the friendliest things you can do for the environment aren’t fashionable.

You can’t show off the new insulation in your attic to your friends, and I’m guessing that your neighbors aren’t going to find your on-demand water heater a particularly fascinating topic of conversation. Unfortunately, unplugging electrical devices when they’re not in use isn’t going to help your public image one iota, but all of these examples are very green… unglamorous, but green.

But there is an up side to energy efficiency that flies under the social radar … $ in your pocket, and I’ve never heard anyone argue that money isn’t sexy!
