Building Services

Mechanical ventilation and heating/cooling systems are a common feature in many buildings. From Air Handling Units, Fan Coil Units (FCU), or chillers serving commercial offices, kitchen extract fans to a restaurant, or heat recovery units (MVHR) serving modern residential apartments, all these building services systems have the potential to result in complaints due to noise if the acoustic impact is not considered at an early stage of the design.

Planning applications for new building services equipment will often require an assessment of noise to nearby noise-sensitive properties. This assessment is usually based on the methodology of British Standard BS 4142:2014, although some Local Authorities have their own unique assessment methods set out in their Local Plan or Development Framework policies. We would normally undertake a background sound level survey, carry out calculations to predict noise from the proposed equipment and, where necessary, provide a specification for an appropriate noise mitigation strategy.

Mechanical equipment also has the potential to cause nuisance to within the property being served. We utilise detailed computer models to calculate levels to inside proposed developments, for example FCU’s serving an office or MVHR units to within residential dwellings. Calculated levels are then compared against appropriate limits set out in BS 8233:2014, CIBSE guidance, or project specifications and where necessary noise control treatments are designed accordingly.

Unfortunately, we are also regularly asked to investigate complaints, where the noise or vibration impact of new equipment was not considered prior to installation. Whilst our innovative approach and experience means we can usually design successful remedial treatment, it is invariably more cost-effective if this had been implemented at design stage. We therefore recommend you speak with our experienced team at an early stage of your development.

Testimonials

"I want to share with you my appreciation for the honesty and sincerity you have shown throughout our work together.

It’s getting rarer these days that clients’ interests are put ahead of pressure to generate fees.

I would definitely recommend you to others."

Philip Catterall

"I have had the pleasure of using ACA Acoustics’ services on a high-end residential project in Vauxhall, London.

The commitment and proactiveness received from Rob Cant and his team was greatly appreciated on an extremely challenging and short time-framed project. This resulted in ACA Acoustics providing acoustic consultancy services on the current 51-storey commercial fit out project in Central London.

I would not hesitate with recommending their services as they are my preferred company for acoustic consultancy."

Joe Wu – T Clarke PLC

"I have been using ACA Acoustics during my employment at different companies since Rob set the business up in 2012. Rob and his team offer an excellent service and very competitive costs for carrying out acoustic sound surveys and reports. In the fast pace nature of the hospitality client field their fast turnaround is greatly valued and helps me to build a robust offering to my clients."

Craig Ballantyne – Spiritus Technical Services Limited

"We used Rob from ACA Acoustics and would highly recommend their services. The work was carried out to an extremely high standard, these guys obviously know their business.

There was some opposition to our project and those opposing employed an independent acoustic agent to try and discredit the report Rob had produced. However, the other report was thrown out and deemed totally inadequate and the Local Authority praised the report submitted by ACA Acoustics.

As I say, these guys know their stuff and are extremely competent and most professional."

Sanchia Ascroft – The Thatch Barn, Yelling

"ACA Acoustics’ practical understanding of the HVAC industry and professional yet common sense approach to finding the right solution for each project is the reason why I’d always choose to use them on my projects and recommend them to my clients."

Ed Fellerman – Chapman Ventilation Limited

"I’ve worked with Rob and ACA for a number of years on numerous projects, and their proactive approach and negotiation skills have helped my clients and I overcome various difficult challenging noise issues to secure tricky planning consents.

As a planning consultancy we have worked with various noise consultants and I have found ACA to be the most pragmatic and adept, going beyond simply undertaking noise calculations to help find solutions and fight our corner when needed."

Mark Shearman – Firstplan

"I use ACA Acoustics to assist with all our projects which require an acoustic assessment. They also provide the acoustic design for separating walls and floors to comply with The Building Regulations Approved Document E.

Their straightforward and practical advice complements the service I can offer to my clients and I highly recommend their service."
