‘Experimental Investigations Into The Functioning Of A Supply Air Window In Relation To Solar Energy As Determined By Experiment And Simulation’ with M. McEvoy, in Solar Energy, vol. 80/5, pp 512-523. (May 2006) ISSN: 0038 092X
The inspiration for the work carried out in this article came from an EPSRC project to investigate all aspects of supply air window design. This particular journal article dealt with the how a ventilated supply air window of different dimensions performs under the influence of solar radiation in terms of the pre-heat available from the window, u-value and solar gain factor. It was carried out at the advanced test cell facilities of the Energy Monitoring Company in Cranfiled, UK.
The article described work that was part of a large EPSRC project looking at all aspects of supply air window design it relates closely to other work carried out under the auspices of this project.
This work was carried out as part of an £100K EPSRC funded project which was rated ‘Tending to outstanding’ by the EPSRC at the end of the project. This is their second highest rating.
The knowledge gained during this and other work carried out under the auspices of the project have lead to the formation of a company by Prof Mike McEvoy and myself to market an energy-efficient whole house ventilation system, called Dwell-Vent, based on supply air windows coupled with Passive Stack Ventilation (PSV) systems. An outcome form this work indicated a weak relationship between window U-value and window aspect ratio, but a strong relationship between U-value and window area. This makes specifying window U-values much easier as we only need to know the overall window size.
