Over Doing Insulation – the Health Consequences

I have always been a supporter of home insulation. Exactly six years ago I wrote a post which explained the benefits of home insulation but which contained the following caveat:-

Insulation is very important. In order to try and save energy further the Government is setting air tightness standards for new homes. Here, I think, that they are on much more uncertain ground, because although air tightness does keep the heat in, it also comes at a price, and you have to be very aware of that price and what you should be doing if you live or work in an air tight building.

I went on to describe the ill effects on occupants in buildings that are too tightly insulated of carbon dioxide build up.

Recently some scientists have conducted research into the relationship between the air tightness of buildings and asthma. they found that the higher to SAP rating of a UK building, the more likely it was that the occupants or some of them would suffer from asthma. Continue reading

Fatal Advice

As you enjoy the present heat wave that is warming much of the United Kingdom as I write, you might find the temperature uncomfortably hot in your home, if your home has been highly insulated. Insulation is a good way to reduce the use of energy on heat; an uninsulated home emits heat particularly through its roof, and successive governments have encouraged the use of insulation as a means of reducing emissions and energy bills. It is the Government’s major way of reducing energy use in the home and its use is founded on the basis that the easiest and cheapest way to reduce emissions is to conserve energy. Continue reading

The Shrinkage of the Green Economy

Mr Stern now thinks that he understated the consequences of climate change when he wrote his report. He also thinks that the government should engage the private sector in developing economic growth without increasing emissions. I cannot disagree but is not that what the government has been pretending to do for the past four years? Continue reading

CERT and the no brainer of home insulation

The United Kingdom’s energy companies, that virtual monopoly of supply of gas and electricity, are, as part of the various climate change emission reduction targets, obliged to carry out certain measures to reduce the demand for energy from fossil fuel sources. These obligations are known as the Carbon Emissions Reduction Target. It is an ill fitting name, as the “target” is a legal obligation to carry out so many measures, not to reduce carbon emissions but to reduce emissions of carbon dioxide. At the risk of being called a pendant, I would prefer that the obligation was more accurately named, but I suppose “CERT” is an easy to remember acronym, even if it is confusing. Continue reading
