Making small, simple energy saving steps

We are hosting our groups Energymark meeting this weekend.... with winter well and truly upon us and one very cold week just gone (I don't think we got above 4oC or so for about 5 days) it was timely that we starting making some more small energy saving steps.

We checked the windows and doors for draughts the other day - using an incense stick on a windy day.


We had sealed doors last year bit I just wanted to check the windows and recheck the door seals.  I did not find any big draught spots that need sealing - which was good.

We have been contemplating double glazing some of our south facing windows - to reduce both heat loss from our south facing bedrooms and to stop the condensation that builds up on the windows and creates a damp mouldy inside of the window.  But have not found the time to chase quotes etc at the moment and to be honest we are a bit nervous about the potential costs.  

So we decided to keep finding some small, simple energy saving steps to do around the house.  Yesterday we made simple pelmets for all the living room windows. This is the view of the top of our curtains before our simple pelmet installation - note the close to 10cm wide gap between the curtain and the window frame.  Air can circulate through this gap down past the window, resulting in the air being cooled by the cold air outside the window.  As you can imagine - this could develop into quite a cooling current or draught in the room.


To stop the air circulation down past the window we simply put a piece of timber over the top of the curtain - resting it on the curtain track supports.  You can see in the image below how the air can no longer travel down behind the curtain.
 

I think it cost about ten dollars for each window - and comparing the before and after of this simple solution there does seem to be a noticeable reduce in the draft or flow of air down past the window since putting on our pelmets.

You could not get much simpler or cheaper than that.  What is more you can barely see the pelmet we installed as it sits directly on top of the curtain track.


What simple energy saving things have you done around your house?  Have they made a difference?

Slashed feed-in tariff for solar power in NSW

Not sure if you heard the news..... but in NSW the gross feed in tariffs for solar power have just been reviewed and reduced from 60 cents to 20 cents a kilowatt hour!!


We have our solar array generating and feeding into the grid already so our 60 cents a kilowatt hour is locked in until 2016.... although I think there is a 300 megawatt cap.  However, if you were considering installing solar power but haven't signed an agreement yet you will be stuck with 20 cents per kilowatt hour - which for most will make the installation of solar panels an unappealing and non-viable choice.

A range of news articles have been published on the topic - here are some if you would like to read more.

New South Wales is slashing the gross feed-in tariff for its solar bonus scheme because it is costing too much - Sydney Morning Herald.

Sustainable Living Week in Orange

It was Sustainable House Day on Sunday 12th September.. in Orange the week following was Sustainable Living Week and we participated in a few activities.  In my role as the local Landcare coordinator and as a teacher at our local TAFE I helped out on a infomration table at the Sustainable Living Expo last Saturday and then we spent most of Sunday looking through some local sustainable homes... and here are some photos I'd like to share.

We started at this house... a house feature in Sanctuary Magaziine



Water features are always a hit with the kids..... we plan to get some water features into our garden...


We loved all the north facing windows we got to see... and are so jealous that we have a 1980's house with very little northern aspect..


More north facing windows..


A small urban permaculture garden......


A 1980's house that was designed with good northern aspect...


A deciduous vine on the western wall..


I would have liked to see more houses that have been retrofitted to improve efficiencies that were not designed for in the first place but we did get to see some good ideas in action.
