Dear readers and visitors of the OliNo.org website, I would like to share a part of my experience as a Dutch visitor, when I was travelling in the warm and deep South of the USA during October until January of 2009. In December I spent some time in beautiful Sedona (Arizona) where I encountered a dome house in a rural area.

On a cold day, I was on the (non heated) attic of my house where the central heating pipes are running. When I touched the insulation around the pipes, I noticed they were feeling warm. This means despite the pipe insulation, warmth is escaping from the central heating pipes.

The energy consumption of an electrical doorbell is very inefficient. It uses energy 24 hours/day while being used only a few seconds per day. In this article, I describe how I reduced the energy consumption of my doorbell.

This article shows that you can save energy by converting an old freezer into a refrigerator. The result is a refrigerator that is more economical than the most efficient A + + refrigerator (This is an indication of the most efficient appliances on a European efficiency scale).

In most electronic equipment, a low-cost EI-core transformer is used, which is much less efficient than a toroidal transformer. This article shows that, quite some energy can be saved by using a more efficient transformer.

Replacing the 250W of halogen bulbs in a torch lamp by 16W of LEDs

This article decribes how the energy consumption of a torch lamp with reading light was reduced from 250 Watt to no more than 16 Watt by utilizing the LED units from four dismantled Lemnis-Pharox bulbs.

Every recent house (build from the late 1980’s and up) has one installed: a forced air ventilation unit. Isolation is important, but what most people forget: good ventilation is also a must. Ventilation and isolation go hand in hand… In my house a system was also installed, with as a beating heart the JE StorkAir CMFe ventilation unit. The noise it emitted was disturbing (for me), and after a calculation I was amazed. This thing wastes lots of energy, and emits noise also…. Therefore I compared it to another ventilation unit (the Itho EcoFan 2) and… immediate upgraded this system for a brand-new Itho unit.

To make the most of this Christmas I decided two write my second column. In this article you can read about how to transform a 300W halogen fixture to one that allows an energy saving light bulb. I have done this just to demonstrate that it is not hard to find energy saving projects at home, if you are a bit handy.

The columns on this site inspired me to look at my energy consumption at home. Out of curiosity, I wondered whether I was throwing away money. I found out I was. It seems that with some simple actions, I am able to save 175 € per year…
