How can I cool my loft?
I have an extremely hot loft, which is keeping the top half of my house hot
as well. I'm running 2 large air conditioners upstairs, but the heat isn't escaping through the loft which is at least 10 degrees hotter. Downstairs is around 5-6 degrees cooler than upstairs. I don't have a loft skylight (nor the will or cash to install one), so does anyone have any ideas on how to cool the loft so that I can get rid of some heat upstairs? Thanks! |

I have the same problem - it's a bit like living inside a storage heater in the current hot weather. I don't have any aircon upstairs, but I've found that putting big fans in two open windows to shift as much air through the upper floor makes a big difference. This cools the house quite quickly once the temperature drops a bit in the evening. I put one fan on the cooler north side of the house to draw air into that room, and another blowing outwards in a window on the south-facing side, and leave the doors open to allow a through draught I'm also going to improve the insulation to prevent the heat in the loft going through the ceiling into the upper floor. Hopefully it will also help my winter fuel bills. There's only a couple of inches of insulation at the moment - way too little by today's standards. Mike |

Our house is a mid-terrace, so in the winter we don't use much heating, as the front and back are sheltered, the loft insulation is good and the neighbours keep us warm.... but it's horrible in the summer. Hardly any breeze and the air is very still. |

Oh yes it does:-) EG my house was a baking 25C inside and 31C outside with no air movement, how is opening a window going to cool it down? As I keep on saying, that depends on the design and how the building is operated. If it has suitable high level windows or vents then the hot air will escape through them and draw in cooler air from lower down, moderating the temperature during the day by counteracting solar gain. Leave the windows open at night and the house will be cool in the morning. With decent insulation it will not become too warm the next day. In the absence of suitable vents proper design will include windows that can be safely locked open for the ground floor and any other easily accessible windows. While nothing substitutes for proper design I have managed to keep mass produced houses cool by suitable ventilation. One tip is to operate the windows so that the air drawn in comes from the side of the house in shadow. This is a subtle process. Gales through the windows mean they are not at the correct settings. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

Upstairs it rapidly shot past 30C as thecomputer equipment heated it up.. Its very hard to cool BELO ambient..your best bet is to install thermal mass that will keep cool during the day and release its heat at night. Lofts will often rise well ABOVE ambient due to solar heating. All you can do is thatch the roof really :D Its the case for having insulation OUTSIDE the structure...keep the thermal mass inisde and moderate extremes.. Ventilation may help to reduce the loft to ambient temp, but thats only if the wind blows.. |

Congratulations, though it was unnecessary to conduct this experiment as I would have told you this if you had asked. curtains mostly closed, A sensible way of reducing solar gain. Ventilation may help to reduce the loft to ambient temp, but thats only if the wind blows.. Incorrect. Hot air rises. With suitable high and low level vents the temperature in the loft can be moderated.

Not it won't, I disagree, having seen all sorts of naturally ventilated buildings. I've seen hundreds of various ages in very hot countries. The best that can be said is that they work a bit. Ventilation serves two primary purposes. Firstly it prevents condensation and rot. Very little air flow is required to achieve this and a house which becomes unbearably hot may still have quite sufficient ventilation to prevent either. Secondly an air flow through the house creates wind chill so people feel cooler. The air is still at a high temperature - ventilation cannot cool a house to below ambient. It is possible to have passive cooling to below ambient but only by utilising a passing lake or deep buried ventilation chambers. Neither are very practical for 33b Acacia Avenue. the upstairs is going to be too hot in summer. Cross. The upstairs may be too hot in summer, but only if the house is badly designed.

Most people also don't consider heat generating devices such as refrigerators and freezers to be "bad design". Modern building regulations go overboard on keeping heat in but totally ignore cooling. The net result is an increasing number of houses which are uncomfortably hot in the summer and the inevitable consequence that people fit air conditioning to remain comfortable. Near here are a collection of up-market "apartments" each supplied with an electric Aga (I agree, an entirely idiotic device). These are less than two year old yet I'd guess about a quarter are now sprouting air conditioners. Secondly, some houses are used for work. This involves heat producing devices such as computers and lights. Home offices are often in a spare bedroom so the heat contribution makes the second floor (which is always going to be warmer than the ground floor) even more uncomfortable. However, you do have a point - many houses are not adequately designed. However they exist and peoples lives are tied up with them. What do you propose should be done with all these badly designed houses? There are numerous greeny house is Milton Keynes and Oxford which are abandoned in summer because they are unbearable.

Suitable and adequate loft ventilation to prevent rot will have almost zero effect upon temperature in the loft. That depends on how it is designed and operated.

Drivel's input aside, a deciduous climber up the south side can take a fair heat load off. So can a white roof. I've also wondered about retrofitting a wall cavity fan to cool the wall down at night time. It would need an effective filter to avoid clogging the cavity with muck over the years. And of course it only works with cavity walls that cant be CWIed, which is a minority, but still a significant number of buildings. NT |

There is no damp course. Not least because if the cob dries out it starts to crumble. So it has a high thermal mass, external insulation and evaporative water cooling! It's lovely and cool in the summer and warm in the winter. Yep. These factors are BEGINNING to be appreciated as we start to get too hot summers as well as dreary cold winters.. In fact the humidity outside was such that the air coming into the house via the windows the spouse keeps opening 'to cool the place' - despite the fact that the house interior is some 5 degrees less than outside air temperatures - cooled enough to set a humidity sensored extractor going.. Mass inside, insulation outside, and deep overhanging eaves is as good as it gets this weather.

Secondly, some houses are used for work. Indeed. I know several and none have air cooling units. What do you propose should be done with all these badly designed houses? Learning from past mistakes and gradually modifying the mistakes. Of course, I am amazed you have never heard of them as they regularly appear in greeny propaganda leaflets. Milton Keynes and Oxford are a long way away. Your claim that if the loft is hot there is a risk of rot is fatuous. Excellent, another dogmatic statement. The reality is rather more complicated, as it depends on why the loft is hot. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

With the appropriate use of the various ventilation options my 1960s house remains at about 20-22C even in the warmest weather. That is true of the south facing public rooms and the north facing bedrooms. The walls and roof are reasonably reflective, both are insulated. However it does not have external shading. I do ensure it is cooled overnight, by ventilation. However, I do understand what is going on and how to get the building to behave as I want it. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

Actually I would be, but for two reasons. - additional recreational area - wine storage. Unfortunately the proletariat does not seem to agree with this notion. |

I suppose with cellars, most UK houses would then be three-storey and have all those complicated fire regulations. Germans et al seem to cope though. Owain Apparently they seem to have gone off Italian pizzas, although I'm not sure what that's about. However, they needn't worry. Dr Oetker comes to the rescue. If you have satellite TV, he is regularly there advertising his great products. http://www.oetker.de/wga/oetker/html...664d7m.de.html The thing is... if I was looking for really good authentic Italian pizza cooked lovingly in a woodburning pizza oven, would I immediately think of the good Dr. Oetker? I'm sure that he's a very nice chap and everything, but somehow something is missing. It all looks reasonable on paper and I am sure that it's wonderfully hygienic but it doesn't quite do it for me. I have it on good authority that his next marketing masterpiece is the compact fluorescent light bulb. |

The land price is so high because land is artificially kept high, they skimp on the house. |
