Building Facades - Can they mitigate rising urban temperatures?

Posted on December 1st, 2016

Brian Murphy | Green Building Encyclopaedia

A recent announcement anticipated temperatures of 48 degrees C in London in 2050, 14 degrees higher than the Midlands peak of 34 degrees C in July 2016. Urban climate specialists argue that building façade design needs to respond to alleviate the consequences of future high temperatures.

Today’s 100% glazed sealed facades, favoured by letting agents and developers, (and often essential in the noisy trafficked and...

A day out with The Green Register

Posted on November 1st, 2016

Bronwen Thomas | Associate, Pollard Thomas Edwards

A window to another world… airtightness, wet stone, fancy sticky tape and ‘breathing’ walls. How we can reduce energy use, but through two very different methods, but with the same concern for moisture within the wall.

When I agreed to facilitate a day of TGR training, I wasn’t bargaining for such a mind expanding day that covered everything from the cultural impact of weather on the urban geography of the British Isles, to magic...

Peak Wood

Rob Borruso

We live on a finite planet, resources are limited, most stuff is running out etc. The good news is that there are resources that rely on the sun in one way or another, that are getting constantly renewed, i.e. renewables. These are solar, wind, hydro and biomass (or woodfuel). But biomass is not quite a 'renewable' as we've assumed even without the issue of using arable land to feed power stations instead of people.

As we all know the two 'big' renewables, wind and sun, have some intermittency issues for which...

How will the Fifth Carbon Budget shape future development?

Posted on September 1st, 2016

Thomas Vazakas | RPS Group

In 2008, Parliament introduced the Climate Change Act. The Act, which is independent from European Union (EU) legislation, established a legally binding target to reduce UK greenhouse gas emissions by at least 80% by 2050, compared to 1990 levels. The recent vote to leave the EU does not change this commitment.

To drive progress and set the UK on a pathway towards this target, the Act introduced a system of carbon budgets to be produced in successive five year...

Reducing hot water demand in Passivhaus dwellings

Posted on August 1st, 2016

Cath Hassell | ech2o 

The Passivhaus standard is recognised as a methodology that has a major role to play in reducing the 50% of CO2 emissions that come from the UK’s built environment. This is either in a new build scenario or as an EnerPHit to existing buildings - always assuming that Brexit doesn’t mean it will no longer have validity in the UK. But to my mind it has one major flaw, and that is the absence of a design standard for hot water use. 6% of CO2 emissions in the UK come from...
