 Although the provision of the new external wall brought many benefits to the overall design of the building, there have been secondary consequences that have had to be addressed. Before the external wall was built, the kitchen windows opened directly onto the access walkways. However, with the introduction of enclosed walkways the kitchen windows had to be replaced with fixed fire rated window units allowing for a protected means of escape in event of a fire. It was also necessary to provide ‘purge’ ventilation to the kitchens using intermittent extract fans (in addition to the MVHR ventilation) with ducting through to the external to purge pollutants. This did pose a challenge to achieving the airtightness requirements of the building but a solution was found through fitting an in-line damper within the extract ductwork so when the intermittent fans were not in use, the ductwork would be sealed and airtight. Although the provision of the new external wall brought many benefits to the overall design of the building, there have been secondary consequences that have had to be addressed.
