Acoustic Consultancy & Testing

HRS have a highly trained and experienced team of acoustic testers and consultants with in-depth knowledge, having worked on many project types, from schools, healthcare projects and offices to large residential and other commercial projects.

HRS’s extensive experience means you can be assured that you are receiving the very best practical and professional advice, ensuring your project achieves its desired acoustic targets. HRS can get involved at any stage of the project, but for you to maximize on the savings that HRS can offer you, early involvement, reviewing and designing out potential issues at the design stage, could save you money and reduce your risks.  If you would like examples of where or how HRS have done this in the past, please contact the HRS Acoustics Team, who would be happy to supply this information and discuss any requirements you may have.

As with so many of the services HRS provide, something that cannot be emphasised enough is to contact HRS early. When it comes to acoustics, it is never too early to be thinking or planning ahead. A call or an e-mail to HRS will cost you nothing but could save you lots. Designing out potential issues at an earlier stage

If you are unsure of the Acoustic services you require please call 0800 030 4391 and one of our Acoustic Consultants will help guide you through the acoustic design process and let you know where HRS can help. Alternatively, email and one of our Consultants will call you back.

Extra BREEAM Credits

There is still much confusion when it comes to BREEAM, this often leads to many of the earlier BREEAM credits being missed which can then lead to the desired BREEAM rating not being achieved.

HRS can help you gain these much needed extra credits, in addition to HRS having BREEAM assessors that will work along side you throughout the life of your project, HRS also provide the following in-house services that can help you gain those much needed extra BREEAM credits.

Design Stage Credits:

  • Ecological surveys and reports including landscape and habitat management plan (up to 8 credits)
  • SBEM calculations (up to 12 credits)
  • Flood risk assessment and surface water run-off calculations and report (up to 5 credits)
  • Passive design analysis (1 credit)
  • Life cycle costing (up to 3 credits)
  • Life cycle analysis (2 credits)
  • Thermal modelling- adaptability for a projected climate change (1 credit) (this wants to come after the thermal modelling)

Post Construction Credits:

  • SBEM calculations (up to 12 credits)
  • Post Occupancy Evaluation (1 credit)
  • Air tightness test plus thermographic survey (1 credit)

For more information on any of the above services click here or call 0800 030 4391 / email and one of the HRS team would be happy to help you. Budget costs for the above services can be provided on request.

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 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 to discuss or arrange for these services to be carried out.

Thermal modelling example

A 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: 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.

Life cycle costing, carbon and environmental impact are increasingly important considerations for building owners and designers. HRS has deployed the latest analytical tools to help its clients make the most informed choices possible with regard to minimising whole life cost and environmental impact.

Using IMPACT-compliant software, HRS is able to provide life cycle costing and life cycle environmental impact analyses, attracting 3 credits under BREEAM criterion Man 02 and 3 innovation credits under Mat 01 (exclusive of the potential credits associated with the materials themselves). The IMPACT standard represents a step change in the accuracy and sophistication of life cycle analysis.

The analyses utilise HRS Services existing deployment of IES-VE software in conjunction with the BRE’s building component database. The approach is in line with BS EN 15978 2011 Assessment of environmental performance of buildings.

The life cycle costing can be built up from the client’s capital cost plan or developed from first principles. In both instances the analysis requires a 3D model to be imported as an IFC or NWC file from the client’s BIM model or built up by HRS from 2D drawings using ModelIT or Sketchup. Life cycle costs can be provided as real, nominal or discounted using a rate predetermined by the client.

The life cycle analysis is undertaken on the same base model and provides results in terms of both kgCO2 and BRE Enviropoints. The latter are based on 13 environmental indicators, including water extraction, human toxicity, mineral resource depletion, eutrophication, acidification and ozone depletion. The 60-year life cycle analysis, which reports on the whole life greenhouse gas emissions for each building element, will attract the 2 innovation credits under the BREEAM criterion Mat 01 and support up to 6 credits in the Mat 01 main building elements assessment, depending on building type.

The BRE material data used for the life cycle analysis is based on a publicly available methodology that has been peer-reviewed and conforms to ISO 14040, ISO 14044 and ISO 21930. At present the dataset is relevant only to the UK, but BRE is working with international partners to produce datasets for other regions.
