Breathing buildings selected as 2014 new energy pioneer

7 April 14

Companies from around the world are recognized as leaders driving change in the energy system..

Breathing Buildings wins patent dispute

21 March 14

Breathing Buildings, the natural ventilation specialist, has successfully defended the Cambridge University Passive Stack patent, filed in 2006.

Are eco-friendly practices becoming more common in modern building?

26 March 14

Sustainable building design is very much mainstream concept in contemporary building. Planning conditions and building regulations require more energy efficient buildings and often some element of on-site generation. So, given that energy efficient building design needs to be at the core of a new building programme, how are we doing at really changing the world? Clearly the easy answer is that one can always do better. But how? Where are the big opportunities?

CIBSE - CFD vs Experimental Modelling Seminar

17 March 14

Breathing Buildings Managing Director Dr Shaun Fitzgerald will be presenting alongside other experts from the industry on the 30th April 2014 at UCL in London at a CIBSE run event discussing different ways in which to model buildings.

Introducing the NVHR

23 Jan 14

Breathing Buildings developed the e-stack® F-series range to provide mixing ventilation via the façade, however in spaces with a low floor-to-ceiling height and limited façade area a more discrete solution can be preferable.

Christmas Jumpers

On Friday the 6th December Breathing Buildings held a Christmas Jumper day to raise money for Save the Children. While the term "high quality" is not normally associated with Christmas Jumpers, the team managed to demonstrate some particular… stunning/ spectacular / "special" examples of this festive line of apparel.

Water bath modelling at different building scales

24 Oct 13

Water bath modelling is a powerful way of examining the various flow regimes that may occur within a naturally ventilated building. It involves creating a scaled Perspex model of part or all of the building, along with its ventilation openings. This model is submerged in water and heat gains on each floor are created by supplying power to hot wires representing the locations of heat sources on each floorplate.

The Science of Water Bath Modelling

16 Sep 13

Water bath modelling of ventilation flows in buildings is an extremely powerful tool at the design stage of a building. What other technique for example enables you to easily view in three dimensions a transient flow pattern in a building?

Are you sitting comfortably?

20 Aug 13

Yes, thank you! CIBSE TM52 was first tabled at a DTM where I was present a few weeks ago. It was at least 32°C outside and I was sitting comfortably in a naturally ventilated building. Internal air temperature was in excess of 30°C, I was wearing a suit, there were many people in the same board room as me and we were all comfortable.

Why we use water bath models and the role of CFD

18 Jul 13

One of the traditional methods of analysing air flow patterns in buildings with topologically complex features is computational fluid dynamics (CFD).

The Priority Schools programme explained

30 May 13

The Priority Schools Building Programme marks a new dawn for UK buildings. The programme is accompanied by a new set of regulations regarding various aspects of the design including ventilation. The reason for the new regulations stems in part from the fact that a number of schools built in the last 5 years have simply not been energy efficient.

Bridging the divide: From Architect to Engineer

09 Jan 13

Throughout my first year with Breathing Buildings my business card said ‘Consulting Engineer’, but with a first degree in Architecture, I felt like maybe I should go about getting qualified as an engineer.

Design Guidelines or “What do we really want to achieve?”

18 Oct 12

At Breathing Buildings, we work across a range of sectors of the construction industry, from schools to healthcare, retail to offices, as well as receiving enquiries about everything from railway switchgear sheds to amusement arcades!

A Cool Way To Save Money

26 Sep 12

DURING the last 20 years thousands of commercial offices and public buildings, including schools, theatres and hospitals, across the UK have adopted natural ventilation for its energy saving benefits. However, up-take in the retail sector has been much slower, despite the fact it is one industry that stands to gain significantly - particularly with respect to reduced refrigeration bills.
