At Breathing Buildings we care passionately about changing the
world and have world experts in Natural Ventilation to help us. So
we want to share our thoughts with you and would love to hear what
you think too.
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.
The Science of Cold Draughts

The science behind cold draughts and why simply putting an opening high up in the room will not solve your problem. Don't take our word for it but follow the science and let your building breathe.
A help or hindrance?
27 Apr 12
I am often asked about my opinion on the PassivHaus design principles for the UK. Where do I stand, have we got it right? It isnatural to think that a new, improved building standard is helpful, but many professionals have concerns about applying it blindly. Does the PassivHaus standard really move us forward in our desire for improved energy efficiency or does it actually hurt us? Do we in fact make things worse?
