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...

The latest instalment in the Zero Carbon Homes saga is rather shocking. Unlike previous chapters which have seen an almost understandable watering down of the policy, this time the Conservatives have let rip their true blue colours! George Osborne has completely given up pretending that the Tories care for environmental policy, and has lead a U-turn on policy that had achieved cross industry...

At the end of last year, I made a comment in one of my TGR blogs about the demise of the Code for Sustainable Homes stating: ‘For seven years, we have had a nationally recognised, holistic standard for measuring the sustainability of new buildings and in my humble opinion, abolishing the Code for Sustainable Homes (CfSH) earlier this year has been a big...

The reuse and refurbishment of existing buildings with their embodied carbon is intrinsically sustainable, provided that they can operate effectively and efficiently and that they are located in a sustainable location. But are all buildings really suitable for refurbishment and how can a balance between sustainability and return be struck?
Given that we are just climbing our way out of recession, investment still mainly concentrates on the...

Two things have been vexing me quite a lot recently. Firstly, the resistance to actually getting things done caused by all the legislation I (we) have to deal with these days. And, secondly, ever since the radio broke in my digger, which of 300+ albums stored on my phone to play next.
I'll tackle the more important issue first. I've various apps on my phone that claim, after I make an initial choice, to be able to compile play-lists for me. Aside from the fact the apps don't know whether I'm path smoothing...

How is the Energy Efficiency Directive changing the way we do business? Is it really achieving its goals or is it just a soft-touch regulation without real tangible achievements?
Overview and Policy Context
Several regulatory instruments have been implemented within the UK to ensure that the UK achieves the cumulative final energy saving target of 27.86 Mtoe by 2020 (2014-2020 period), as per its NEEAP (National Energy Efficiency Action Plan) in...

Legionella pneumophila bacteria (first identified in July 1976) are found in all types of nutrient-rich fresh water environments, including rivers and streams. From these sources they enter and colonise man-made water systems such as humidifiers, cooling towers and hot and cold water systems. The bacteria are dormant below 20°C and do not survive above 60°C. Legionella only become a risk to health if the bacteria multiply rapidly, which occurs when temperatures are between 20-45°C...

Anyone who is used to working in the commercial sector and looking at scoring easy BREEAM points will already know all about total washroom control (1). For the rest of you think urinal controls only bigger, better, faster, exerting control over all the water supply into a toilet block.
Benchmarking of schools
The main way of comparing different buildings with regards to how much water they use is based on the number of building users. For schools the...
