What are noise and vibration surveys?
Noise and vibration surveys are undertaken in order to determine prevailing noise and vibration levels in the vicinity of a project. These noise and vibration levels may have an effect on the design of the scheme, whether that is in needing to limit noise intrusion, guarding against external services or activities contributing significantly to the local environmental noise, or ensuring that vibration from nearby sources does not potentially damage sensitive equipment.

Planning and noise
Using the results of HRS noise and vibration surveys, HRS’s acoustic consultants can provide you with the advice you need and work with you to ensure you obtain planning permission.

It’s good to be aware that some Local Planning Authorities may impose a variety of conditions covering noise and vibration issues associated with a development. HRS’s acoustic consultants are here to help – HRS can provide acoustic assessments for the discharge of these conditions.

sources-of-noiseProtecting people from noise
An important factor in construction and developments in residential communities is ensuring that the amenity of existing and future occupants is protected from noise intrusion; Local Planning Authorities routinely apply noise level limits to developments in order to do this.

Noise surveys can help identify if there is a need for the design of a building to take a special approach to limiting the potential for noise nuisance. It’s best for surveys to be undertaken early so that these factors can be understood from an early stage.

If you are working on a development that would typically be regarded as having the potential to increase the exposure of nearby occupants to noise during construction or use, or if development is being proposed close to an existing source of noise, such as a busy road then you should expect that a noise survey will be part of the planning requirements.

Effects of vibration
Vibration is a typically more rarely thought of source of annoyance for building occupants, but can have similar effects to noise exposure. HRS are able to undertake vibration exposure assessments of proposed schemes where existing or future impact of vibration may be seen as being a risk towards the serenity of occupants, adequately protecting sensitive equipment or causing superficial or more severe damage to buildings themselves.

larkhill_retirement_villageThis normally relates to in the impact of existing noise sources, such as roads, rail, aircraft and industrial/commercial noise etc on a proposed residential development.

If you are working on any development that would typically be regarded as having the potential to increase the noise levels to nearby residents, then you should expect that a noise survey will be part of the planning requirements.

HRS have a full team of highly trained Acoustic Consultants with years of practical experience, who would be happy to have a chat with you and look over your information. Calling HRS costs you nothing, not calling HRS could end up costing you a lot of money, time and problems down the line/later on.

acoustics_design_review_HRSAnyone that has had to deal with the acoustic properties of a building will know how important it is to get the right advice at the right time from the right consultant.

HRS’s best advice is that it is never too early to make a call or send an e-mail asking the question “What do you think is required on this project?”

The right design for the right scheme
Acoustic design can vary greatly depending on building type, and as the effects of bad acoustics are becoming better understood, it is massively important for buildings to have inherently good acoustics.

HRS can help you to identify the correct acoustic requirements for your scheme at an early stage, and advise on the best means to meet them using expert knowledge of acoustic design. We are always eager to incorporate our up-to-date understanding of cooperative building design to ensure that our advice stands out by fitting in.

Section 1 of Building Bulletin 93 ‘Acoustic Design of Schools – A Design Guide’  (BB93 2003) was formally reissued in December 2014, with further updates issued in early 2015. The design guidance in Sections 2 to 7 of the 2003 version are being updated and are expected to be published in 2015.

The Building Regulations require that all teaching and learning spaces within schools should meet the BB93 performance standards for indoor ambient noise level, airborne and impact sound insulation, and reverberation time. This is inclusive of independent schools, academies, free schools, university technical colleges, sixth-form colleges attached to schools, and nursery/community and adult education spaces within school complexes.

In order to comply with The School Premises Regulations and Independent School Standards requirements  speech intelligibility in open plan teaching spaces and operational noise levels (e.g. of equipment within teaching and learning spaces) also need to be considered in school design.

Updates in BB93 2015 (current version 17) include:

  • Performance standards outlined for refurbished buildings.
  • Updated guidance on indoor ambient noise levels for naturally ventilated spaces, in line with guidance to be published in the updated BB101. Guidance also provided for hybrid ventilation systems.
  • Further guidance provided on common situations such as interconnecting classroom doors that may previously have required a derogation under BB93 2003.
  • Reverberation time requirements for Sports Halls and Swimming Pools now depend on the size of the space.
  • Updated guidance on speech intelligibility assessment for open plan spaces, to be assessed via the Speech Transmission Index (STI) – HRS can undertake compliant design stage computer modelling for STI along with pre-completion testing to confirm compliance.
  • Expanded definition of students with special hearing or communication needs.
  • Rain noise requirements are introduced for lightweight roofs (mass per unit area less than 150kg/m2). HRS can demonstrate compliance with use of laboratory test data for lightweight roof constructions in accordance with BS EN ISO 140-18.

IAQUK-Membership-LogoBREEAM 2014 Hea 02 Credits – Indoor Air Quality – achieve easy, low cost BREEAM credits
HRS can help you achieve those much needed BREEAM credits by putting together an Indoor Air Quality Plan (IAQP) and carrying out Indoor Air Quality Testing.

The difference between BREEAM 2014 Hea 02 and BREEAM 2011 Hea 02 is that under BREEAM 2014 Hea 02 you can now get two BREEAM credits, one credit for having an IAQP prepared and one credit for carrying out the Indoor Air Quality Testing.

This is a low cost way of achieving two BREEAM credits, something many people are not aware of but it is worth knowing that even if you fail the Indoor Air Quality Test, you can still get the credit for having the plan.

BREEAM 2011 Hea 02 Credits – Indoor Air Quality – achieve an easy, low cost BREEAM credit
HRS can help you achieve those much needed BREEAM credits by putting together an Indoor Air Quality Plan (IAQP) and carrying out Indoor Air Quality Testing.

This is a low cost way of achieving a BREEAM credit. Please call HRS on 0800 030 4391 or e-mail info@hrsservices.co.uk to discuss or arrange for these services to be carried out.

Why were the BREEAM 2014 / 2011 Hea 02 Credits Introduced?
The reason and aim of the BREEAM 2011 Hea 02 Credits (Indoor Air Quality) is to recognise and encourage a healthy internal environment through the specification and installation of appropriate ventilation, equipment and finishes.

The test is carried out post-construction but pre-occupancy and involves looking for the presence of volatile organic compounds, formaldehyde etc.

The percentage credit weighting for Hea 02 is approximately 1% which makes this a simple and attractive BREEAM claim.

Is your building ready for Indoor Air Quality Testing?
Prior to testing, your project will need to be at or near completion with your HVAC system fully operational for a building purge.

Please also note that where levels of detected VOCs/formaldehyde are found to exceed the prescribed limits, the project team will need to confirm the measures that have or will be undertaken in accordance with the IAQ Plan to reduce the levels so that they fall within the limits.

Please call 0800 030 4391 or e-mail info@hrsservices.co.uk to discuss or arrange for these services to be carried out.

Thermal modelling exampleA thermographic survey is a collection of photographs taken using a thermal imaging camera which show the temperature of a building or object. These highly detailed images show differences in temperatures which can tell you a lot about a building which you may not be able to detect in any other way.

Thermographic Surveys/Thermal Imaging Surveys have many benefits:

  • A thermographic survey report can provide you with much needed BREEAM credits (make a hyperlink)
  • They can show where heat loss is occurring in a building, highlighting inadequate or missing insulation
  • They can locate and quantify thermal bridges (make Thermal Bridges words a hyperlink)
  • They can show the location of air leakage paths through the building envelope (again hyperlink)
  • They can show water leakage tracing from building envelope or internal systems failures
  • You can locate with ease hidden or buried systems like pipes, central heating, under floor heating
  • They are great for examining all buildings, but in the case of a historic or listed building a thermographic survey is a way you can undertake a non-intrusive visualisation of structural or other components.

If you would like more information, advice or a quotation, one of HRS’s very experienced thermographers would be happy to discuss if a thermographic survey would be beneficial to you. Please contact us on 0800 030 4391 / email: info@hrsservices.co.uk or click to go to the KNOWLEDGE Hub ».

BREEAM credits for acoustic performance are awarded under two issues, Hea 05 and Pol 05, concerning internal acoustic performance and the control of noise pollution, respectively.

Depending on the scheme type, up to four credits are available through achieving the requirements of Hea 05. One credit is available through Pol 05, and is not dependent upon scheme type.

In some instances, such as for school design, the requirements of Hea 05 can be met by working to the standards required for Building Regulations compliance; other instances such as residential developments award credits on the basis of exceeding the baseline performance standards required by Building Regulations will require specialist design input from an early stage.

To find out more about BREEAM requirements specific to your scheme call HRS, or view our spreadsheet detailing the specifics of the Hea 05 and Pol 05 credits.
