I travelled once again to the International Passive House Conference which was held in Darmstadt, Germany from the 22nd to the 24th of April. The International Passive House Conference (IPHC) returned to...

The Energy Savings Opportunity Scheme (ESOS) was introduced by the Government in June 2014 and it obliges all large enterprises to carry out an energy efficiency audit every four years. The scheme is required under the 2012 European Energy Efficiency Directive and has a scope which is wider than current carbon schemes, such as CRC, as the focus is on energy, not carbon. ESOS also covers all parts of an organisation’s energy consumption, including buildings,...

If you are working in the sustainable construction field, perhaps you will be having some engaging debates in the pub with colleagues about the best way to improve the performance of existing buildings. I know I am.
On the one hand (the argument goes), some existing buildings are losing so much heat through the elements we need to install as much insulation of whatever type to stop this wasteful loss of energy.
On the other hand there is...

A review by Alain Speed from PDP London architects
I enrolled on the WUFI course with some trepidation. I regarded it as a privilege to have been sponsored by my employer, PDP London, and was determined to get to grips with the programme. WUFI’s reputation and that of the presenters loomed large. Gaining an understanding of the science behind building pathology (relating to harmful moisture) would allow me to make informed judgments when faced with the plethora of information out there about...

The most important thing to bear in mind when installing IWI is, in my view, to consider the large quantity of water vapour generated by building occupants, and what happens to it. A family of four will produce anything from ten to twenty litres of water in 24 hours; two litres while sleeping, a couple of litres bathing and showering, four litres cooking, a litre...

The 1999 Water Regulations (2000 Water Byelaws in Scotland) state that ‘all WC flushing cisterns should be provided with a connection for a warning pipe, the outlet of which is to discharge in a prominent position’ and that ‘an internal overflow discharging into the WC pan shall be deemed to meet the requirements of the Regulations’.
Before 1999 any overflow from a toilet had to terminate in an obvious place and internal overflows were very much ...

The risks associated with retrofitting solid wall insulation are well known amongst ‘green’ building professionals and practitioners. These risks include risks to built heritage, interstitial condensation, poor indoor air quality, mould and under-performance of the insulation.
Concern about roof retrofit is much less prominent and the guidance usually assumes simple situations, rather than the often complex reality. The risks are...

At the recent celebrations of TGR’s 15th birthday, I enjoyed a trip round the Bristol Aquarium, in the company of two colleagues. The contrast in their reaction to the displays amused me somewhat, with one identifying exotic species and relishing big fish in even bigger tanks, and the other declaring he had eaten or cooked most of the exhibits, within the past month!
For me, being able to see flashes of brilliant colour and admire beautiful,...

Passivhaus – What’s the problem?
Post occupancy studies have shown that Passivhaus delivers on its core aims of delivering extremely high fabric energy efficiency with superior levels of thermal comfort time and again with few exceptions. So, why are Registered Social Landlord’s (RSL’s) not universally adopting Passivhaus for some or all new affordable housing schemes?
Some organisations, including Hastoe and Exeter City council, are...

Anyone who lives in a hard water area in the UK (60% of homes) will be familiar with scale in kettles, on taps and shower screens, a lack of lather from soap, washing powder, etc, scum around baths and scratchy towels. While visible scale is unsightly and hard water is detergent hungry, the real issue is the deleterious effect that scale deposits have on heating systems by reducing the rate of heat transfer. This effect is not immediately...
