What's going on over at EcoRenovator
 
I see a lot of discussion going on here and can't help but see there is real interest in home efficiency. So, if you haven't been to EcoRenovator's forum lately you've been missing out on some good stuff going on. Here are a few things.

MetroMPG is trying to squeeze the most from a tiny, old, uninsulated apartment.

I have recently done a lot of work in my attic as far as insulation goes.

We've all been gushing over plans and specs on superinsulated / passive houses. How does a $35 heating and electric bill for December in Illinois sound?

I also built a new efficient computer for myself.

Jwxr7 has setup a very nice small DIY solar PV array and has been tracking his power generation for a few weeks now.

Daox 02-10-2009 12:59 PM

I thought I'd give an update seeing as its been a couple weeks. Come check things out.


jthistle is looking at doing some water conservation with a dual flush toilet conversion.

ftumsh is figuring out how to properly insulate his attic/loft that houses his boiler.

I posted a link to a blog that explains how to get cheap or free solar PV panels.

Of course, MetroMPG finished up the work on his bikegen, a bicycle powered generator made at nearly zero cost.

groar continues his solar pv thread and updates us with the progress and generation hes been getting with it.

Daox 02-18-2009 04:41 PM

Some more updates. Still see a lot of posting going on here so I know there is interest.


I started a new project. It is a clothes dryer heat recovery system for gas or electric dryers.

TimJFowler recently cut his heating bill by 37% by adding additional insulation.

Higgy installed some inline duct fans to boost heat to his living room.

Bob McGovern posted a great write up about small wind power, Part 1.

We've all been mulling over different ideas for rain water collection and reuse.

MetroMPG 02-18-2009 05:30 PM

HEY - don't forget my new thermal floor, which appears to have significantly cut my energy requirements. :)

OK, that's bad. It's not what you think.

Daox 02-19-2009 11:33 AM

I mentioned your thread in the very first post. :p I suppose there was enough updates to give an update here.

Everyone go see Metro's amazing updates! AMAZING!

Daox 08-20-2009 04:37 PM

I haven't posted anything here for quite a while. There are a few bubbling projects going on over on ER. Come take a look.


AC Hacker has been building a home made heat pump for a while now. This thread is really something as well as the work he has done. Anyone interested in heat pumps needs check this out.

Insaneintention has been giving us all udpates on his garden. Higgy has also given us some looks at his garden including his self watering tomato planters.

I just am gathering info on how to insulate my garage.

I'm also looking into ways to setup an inexpensive solar garage heater.

Jlindstrom has posted some info on a DIY MPPT (Maximum Power Point Tracker) circuit. This device can boost solar panel output by up to 15%! Very good stuff to look at when thinking about how much panels cost.

Bicycle Bob 08-21-2009 04:26 AM

I should join that list soon. I had to laugh, though, reading through one long thread about an electric-resistance heated space, where the occupant was careful to minimize more interesting ways to use electricity, which all wind up as heat anyway, except for light that shines out the windows.

Daox 08-21-2009 09:30 AM

Yeah, we're all learning haha. Feel free to comment and help us out over there. :) We'd appreciate it.

Daox 08-24-2009 05:08 PM

Here are some new updates.


I just posted an blog on DIY Home Air Pressure Test. This explains how to do a DIY version of a blower door test. I'm anxious to try this out myself as I know my house has a lot of leaks.

Ben Nelson just lent me some batteries so I can do more ecorider testing.

I found a great instructable on a DIY passive cooled fridge.

Jlinstrom is looking into installing an efficient fireplace in his cabin.

I also found a great CHEAP solar/wind charge controller kit for $15. It even has a dump option on it.

Daox 09-04-2009 03:02 PM

Here is another update.


Binger posted a good article on the honest truth about blown insulation and how you might have been shorted if a contractor did it. Apparently its a fairly large problem.

There has been some new discussion on a post of mine from a while ago. A clothes dryer heat recovery system for electric or gas dryers.

Again, some good discussion on how to get rid of ants. Mostly discussing green ways, but some non-green as well.

There are EcoRider updates to be read as well.

Homeless (Cd on EM here) did some great work with his fridge/freezer to convert it into a very efficient fridge. His energy usage for the month is amazing.


There are lots of interesting projects going on, so come take a look. It would be great to see more too. :)

Daox 09-14-2009 12:22 PM

More updates.


I did some sealing work on the house this weekend. Old farm house, lots of leaks!

Basjoos has been teaching us about how he has naturalized his garden so he doesn't need to till and replant every year.

We've put together a couple recipes for organic weed killer.

Ben Nelson put together a DIY solar hot water heat exchanger

I found a great list about how long appliances normally last.

Daox 09-30-2009 03:18 PM

Some more goings on over on ER:


AC Hacker did a some cool eco hacks to his rice cooker.

Robert Smalls is working on winterizing his apartment.

Ben Nelson made a DIY solar food dehydrator.

Ben is also refurbishing some solar hot water panels.

I did some testing that shows the effect of defrosting on freezer efficiency which is part of an ongoing series on freezer efficiency.


Come check things out and get some ideas. We'd love to see what you are doing too.

Daox 11-10-2009 07:34 PM

There are some great updates this time around.


Xringer has put together a great thread on a DIY install of a Sanyo heat pump / AC unit.

GvilleRenovator has done some recent work in his attic sealing air ducts leaks.

Daox 09-07-2010 01:21 PM

Its been quite a while since my last update here. I figure there are new users interested in home efficiency. So, here are a few things that have been going on recently over at the EcoRenovator forum.

Xringer has been experimenting with his new solar PV panels and trackers.

I recently blew the motor on my electric riding lawn mower.

Gasstingy has been working on his new garage / shop for a while now.

Patrick coated his roof with white roof seal to lower attic temperatures and reduce AC usage.

Trikkonceptz recently picked up a bed fan to reduce AC usage during the night.

Daox 09-24-2010 10:26 AM

Heres some more links for those interested:

Aproldan has started doing work on yet another electric mower. This one is combining a tractor front end with a golf cart back end.

RobertSmalls has broken down his energy usage by appliance and is analyzing how to further conserve.

I've been experimenting with using attic heat to heat my house.

We've been discussing the benefits of enclosed showers.

We've also been talking about thorium reactors and the benefits they provide over nuclear power plants.

Daox 11-08-2010 11:00 AM

Heres another short list of some of the happenings over at ER. If you have any interest in home efficiency I suggest taking a look.

Patrick and nibs have been discussing how to make efficient wind turbine blades.

I've been working on making some interior storm windows for the windows in my sunroom which should triple the insulation value of the window, and easily pay for them self in the first year of use.

Xringer's solar tracker project is showing excellent results as his 500W array has hit over 500W of production.

Robertsmalls is working on a way to heat only certain areas of his house effectively.

We've also had some good discussion going on about low cost LEDs.

Daox 10-23-2012 06:34 PM

I was talking with Darin today and he brought up the idea of bringing this back, and we agreed it was a good idea.

FWIW -- we've moved our home from CFL to LED lighting for two reasons (in order of precendence):

1) LEDs consume less power for same/better lumen output.

2) LEDs produce less heat so can be operated upside-down (where CFL lamps tend to overheat and fail sooner).

Yeah, solar is something else. I got about a thousand watts in 2 diffferent panels. FIrst off if you build a panel of broken cells, the smallest cell will be your bottle neck, so you need to test them all and really go with larger unbroken cells. If you plan on doing grid tie inverters, check the voltage ranges and build your panel or shop for one that has the similar output. Many panels are ment to be connected to a 12,24,36,48, etc battery bank, so the voltage is accordingly. Grid tie panels have different voltage ranges for use with GTIs.

When it comes to multiple panels and MPPT, you need to run all like panels in series or use a MPPT a panel. If the voltage starts to dip too fast due to shading, etc the MPPT wont suck low enough or reset its load to take advantage of what the panels can produce.
