This study has showed that mass walls are un suitable for desert climates and that the timber frame construction is better in these conditions.<br /><br />In a desert climate temperatures still remain high at night even with no cloud cover, this is why the timber construction worked better as it released the heat back out of the building where the mass walls dont.<br /><br />Thanks for your comment, very interesting stuff especially the video link.<br /><br />JanpassivejanGMIThttps://www.blogger.com/profile/07239662021534567332noreply@blogger.comtag:blogger.com,1999:blog-4221282745895063545.post-53163622327396858732011-11-22T14:47:45.553-08:002011-11-22T14:47:45.553-08:00This comment has been removed by the author.PassivEimearHassetthttps://www.blogger.com/profile/03939575690433436986noreply@blogger.comtag:blogger.com,1999:blog-4221282745895063545.post-6009949830196402322011-11-21T14:19:13.156-08:002011-11-21T14:19:13.156-08:00@ Kevin Cunningham and john.

Data was collected from April and October in 2006 because during this period both the heating and cooling systems are shut off. This was so they could analyse the buildings based purely on natural heating and cooling effects so in fairness it probably was a good time to do it.<br /><br />Your points about applying the study elsewhere is a valid one and well made.<br /><br />Thanks, JanpassivejanGMIThttps://www.blogger.com/profile/07239662021534567332noreply@blogger.comtag:blogger.com,1999:blog-4221282745895063545.post-84577620278145611552011-11-21T11:32:15.001-08:002011-11-21T11:32:15.001-08:00This comment has been removed by the author.PassivEimearHassetthttps://www.blogger.com/profile/03939575690433436986noreply@blogger.comtag:blogger.com,1999:blog-4221282745895063545.post-44880369737564303942011-11-21T07:44:51.856-08:002011-11-21T07:44:51.856-08:00I was interested to read this blog about testing o...I was interested to read this blog about testing one construction type against another to determine which type was best suited to a particular area. Found it very interesting to see the pro’s and cons to both types of wall construction.<br />I must say I agree with Kevin’s point about a more accurate study being formed if the measured time was over twelve months and if similar studies were carried out in varying climatic locations.<br />Just to note, the article which I looked at might be of interest to compare. “CEPHEUS – measurement results from more than 100 dwelling units in passive houses” http://www.passiv.de/07_eng/news/CEPHEUS_ECEEE.pdf. In this paper detailed measurements for 11 passive house projects with different sites, planners and construction types from across Europe are presented. <br />JohnPassive Johnhttps://www.blogger.com/profile/17008398713834829699noreply@blogger.comtag:blogger.com,1999:blog-4221282745895063545.post-28113161320380774182011-11-16T09:41:49.430-08:002011-11-16T09:41:49.430-08:00From the results it is interesting to see that in ...From the results it is interesting to see that in the massive house the heat is continuously transferred into the indoor space, which means that the heat stored during the day,cannot be completely released back during night time which makes this wall type unsuitable in this area<br /><br />Also like my own study on the MHRV systems, these results are only suitable for this particular area which is Las Vegas, Nevada. These results couldn’t even be used in other areas of the country such as New York due to the temperature differences. It would be interesting if a broader study was carried out. Maybe if it carried out in different states or countries throughout the world.<br /><br />The data was collected from April to October; maybe to get a more accurate result they would have been better collecting data throughout the year.<br /><br />In this situation great care must be taken with these selection and construction of the walls for heating and cooling with the variation of temperature between 1celcius in winter to 41celcius in summer.Kevin Cunninghamhttps://www.blogger.com/profile/02720332415739727449noreply@blogger.com
