'Outdoor Measurements of the Influence of Aspect Ratio on the Performance of Supply Air Windows’ with M. McEvoy and C.Martin of the Energy Monitoring Company, in Architectural Science Review, vol. 46, pp 313-321 (2003)
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 perform in terms of the pre-heat available from the window and U-value. 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. The work carried out here was towards the end of the project and used designs and methodologies refined during earlier studies.
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 from this work was the demonstration of the improved solar gain factor of the window compared to a double glazed design with much poorer thermal characteristics, thus making a strong case for utilising the window in cold sunny climates.
