Noise and Odour Mitigation Report
12th June 2014.
Dear Chris,
I am writing this report in response to the report published by Simon Renton so that we can get some movement on my planning application (ref: 14/00180/B).
In the report the main concerns are regarding noise and smell. I have taken every possible chance to limit these to the bare minimum using the latest technologies. Attached are details of an odour system call the UV-0 1000 system which is the system that Mr. Renton has requested to be applied to the system.
From a planning point of view we do not want to have a flu protruding the gable/roof ridge height by 1 meter, as is the case in the majority of extract systems. That is why we have opted to use an air filtration system instead of sticking a canopy out 1 meter above ridge height. Working in partnership with the UV-0 1000 air filtration system I am going to use a cowl on top of the ducting called a HNU Cowl. This cowl is specially designed to take the purified clean air and disperse it in a vertical direction, throwing the air up and out of the vicinity. This will mean that there should be no smell coming from the extract at all. Again as a belt and brasses approach I am also going to fit a silencer (PVA 100) to the system to reduce the noise levels to below 45dB at the break out of the flu/cowl. As per the original drawing it states that the actual fan unit will be mounted on rubber mounts in the basement of Number 1 Dale Street. This is underground and situated as far as possible from Number 3. This will not be audible at all to Number 3.
As regards to the concerns in relation to an extraction system to the kitchen of Number 1 Dale Street there should be no concern. There is not a flu system on the drawing because there won't be an extraction in the kitchen. It is not to be thought of as a kitchen and should be more referred to as a preparation room. All the cooking goes on within the range system, the kitchen/prep room is where we store freezer etc and cut fish in preparation for the days service.
With regards to sound insulation between the proposed shop of Number 1 Dale Street and Number 3 Dale Street, Simon Renton on his site visit was of the opinion that the 500mm masonry wall would be sufficient sound insulation. On top of the 500mm masonry wall the wall has been framed and plaster boarded giving another 100mm. So as it stands the wall between the shop and number 3 is at least 600mm thick. I will however take the plasterboard down and put in sound deadening material and then re-plasterboard the wall to give 100% guarantee of no noise travelling from number 1 to number 3.
Finally also enclosed is a drawing to show the flu system through the building and the exit point onto the roof. The exit point has been specifically placed to be as far removed as possible from number 3. With the above steps in place there really is nothing more I can do to make it any better for number 3. I have run my shop for 2 years now with not one complaint of noise or smell and I will make it so that number 3 will have no noise or smell complaints from me.
I hope this report gives you all the information that you require to help move my application forward. If you need any more details or clarification on a certain point please call me on 492670 or write to me at the above address.
Yours Sincerely,
Robert Cowell Director.
