With a tower block refurb Design and Build, air tightness unlikely to meet current new build Building Regs, MVHR was the ventilation strategy. I have queried this as the best option due to likely energy penalties and issues of likely poor design, installation and commissioning causing noise, increasing enerrgynuse and possibly compromising indoor air quality.
Additional concern of course around usability in social housing and high maintenance costs as the Council will have to do filter replacement. Could I have comments on this as I am challenging engineers and project managers on this who fear back to basic calculations? I did my thesis on MVHR performance and occupant use so feel there is an unacceptable risk but would like industry specialist thoughts on this.
Thanks a lot
