APT Floor Plenum Testing Services

APT Sound Testing offers specialized floor plenum testing services, adhering to the “Floor Plenum Airtightness – Guidance and Testing Methodology” (BG 65/2016). Our goal is to ensure your building’s floor plenums are properly sealed, optimising energy efficiency and maintaining a comfortable environment.

Understanding Floor Plenums

A floor plenum is a void located between a building’s structural floor and a raised access floor. This space is utilized for the distribution of conditioned air to the areas above. Properly managed, the air flows from the floor plenum into the occupied zones without leaking into adjacent cavities, risers, stairwells, or other spaces. Ensuring the air flows correctly through the floor-mounted diffusers or grilles, rather than escaping through joints or gaps, is crucial for maintaining the intended air delivery and system efficiency.

Importance of Airtight Floor Plenums

An airtight floor plenum ensures that conditioned air reaches the occupied zones efficiently, providing comfort and saving energy. Leaks can lead to significant energy loss and discomfort for building occupants. Therefore, it is essential to perform thorough floor plenum testing to identify and address any air leakage issues.

Our Testing Methodology

At APT Sound Testing, we utilize a meticulous testing process involving specialised equipment. Here’s an overview of how we conduct floor plenum air tests:

1. Preparation:
   • We remove a temporary tile from the plenum and install a fan housing directly above the opening.
   • A fan is then placed into the housing, which is sealed against the floor.
   • All air handling ducts serving the test zone are turned off, isolated, and sealed to prevent air passage outside the test zone.
2. Testing Setup:
   • Another tile is replaced with a mock tile featuring a drill hole for the high-pressure tube.
   • A series of pressure readings is taken once the equipment is set up. These readings are then compared against the floor plenum air tightness specification.
3. Smoke Survey:
   • If the plenum fails the initial test, a smoke survey is conducted to identify air leakage paths.
   • The smoke survey helps pinpoint exact areas where sealing is needed.
4. Reporting:
   • A detailed report is generated, highlighting any air leakage paths found during the smoke survey. This report serves as a reference for remedial sealing works.

Ensuring Successful Testing

Our team at APT Sound Testing is committed to helping you pass your floor plenum air test on the first attempt. Here’s how we ensure success:

• Site Audit: We arrange an on-site air test site audit as soon as the floor is in place.
• Initial Testing: Conduct an initial floor plenum air test and smoke survey to assess air leakage.
• Remedial Guidance: Provide a smoke survey report to guide your sealing contractors in effectively addressing any identified leaks.

Standards and Specifications

Currently, there is no universal standard for floor plenum testing. The specifications are typically set by the project’s mechanical engineers and are often measured in litres per second per square meter (l/s/m²) at a specific pressure, such as 0.7 l/s/m² at 50 Pascals. Occasionally, the specification might be in litres per second per cubic meter (l/s/m³), in which case the volume of the plenum must be known.

Our Commitment to Excellence

Choosing APT Sound Testing for your floor plenum testing ensures you benefit from:

• Expertise: Our experienced team has years of expertise in raised access floor plenum air pressure testing.
• Customer Satisfaction: We focus on customer satisfaction with a proactive and can-do attitude.

Electrical Hotspots & Infrared Inspections

The importance of identifying electrical hot spots during infrared inspections cannot be overstated. Thermal imaging has been used in electrical system inspections since this technology was unveiled more than forty years ago. The operating conditions of electrical systems can be determined by looking at the thermal photographs of the system’s components and checking the radiometric data.

Thermal Imaging Inspections

Thermal imaging inspections are a great way to monitoring electrical systems because it begins to degrade as soon as any electrical or power system is installed. No matter how heavily a circuit is loaded, vibration, wear and tear, and heat can make electrical connections loose over time. Electrical connections have a natural tendency to degrade over time, and unfortunately these deteriorating connections can cause further faults if they are not discovered and fixed.

>>> Finding electrical hotspots with infrared inspections
>>> image electriclal infrared Inspection
>>> Don’t ignore electrical hotspots

Once hotspots have been identified and the site team is made aware, this information should not be ignored. In our experience ignoring hot spots in electrical systems can lead to several serious risks.

>>> Electrical Fires: Hot spots can cause insulation to degrade, leading to short circuits and potentially catastrophic fires putting lives and buildings at risk.
>>> Equipment Failure: Overheating can damage electrical components, leading to unexpected equipment failures and costly repairs to critical infrastructure.
>>> Electrocution: Faulty wiring or connections that cause hot spots can increase the risk of electric shocks leading to injuries and/or loss of life.
>>> Increased Energy Consumption: Overheating components often operate less efficiently, leading to higher ongoing energy usage and costs.
>>> Property Damage: Electrical fires and equipment failures can cause significant damage to property, resulting in expensive repairs and potential loss of valuable assets

Addressing hot spots promptly is crucial to maintaining safety and preventing these risks. If we detect a hot spot, it’s best to consult a qualified electrician to inspect and resolve the issue in a quick and safe manner.

Comprehensive Guide to BS8233 Noise Assessments

Expertise in BS8233 Noise Assessments

APT Sound Testing boasts extensive experience in conducting BS8233 noise assessments for planning applications across a wide range of developments. These assessments are frequently mandated by local authorities as part of the planning conditions for new build projects such as apartments, houses, and hotels. The primary aim is to determine the potential additional noise that the proposed development may generate.

Importance of BS8233 Noise Assessments in Planning

Noise assessments are crucial at the planning stage to help local authorities evaluate the potential noise impact of a proposed development. This process typically involves:

1. Establishing Existing Ambient Noise Levels: Measurements are taken to determine the current noise environment.
2. Assessing Noise Impact from the Development: The anticipated noise levels from the development are calculated, often necessitating detailed noise modelling.
3. Considering Secondary Effects: For larger developments, the potential impact of increased traffic and other secondary effects must be considered.

Noise Modelling and Control

Noise modelling plays a pivotal role in predicting the noise impact of a development. It allows us to calculate expected noise levels and assess various noise control options. This modelling helps in designing effective noise mitigation strategies, ensuring that the development complies with noise regulations and minimizes its impact on the surrounding environment.

BS8233 Noise Exposure Categories (NECs)

In the UK, planning and noise assessments are guided by BS8233, which defines four Noise Exposure Categories (NECs):

1. Category A: Noise levels that are unlikely to be of concern.
2. Category B: Noise levels that may require some mitigation.
3. Category C: Noise levels that would require significant mitigation.
4. Category D: Noise levels that would generally be considered unacceptable.

The NEC applicable to a site dictates the level of noise consideration required for granting planning permission. Noise-sensitive developments proposed in high-noise areas, or areas expected to experience high noise levels in the future, must particularly adhere to these guidelines.

Brownfield vs. Greenfield Sites

Government guidance encourages the re-use of brownfield sites, which are often subject to higher noise levels compared to greenfield sites. As a result, noise assessments for brownfield developments are crucial to ensure appropriate noise mitigation measures are in place.

Determining and Mitigating Noise Levels

The NEC for a development is usually determined through noise monitoring. Based on these findings, potential mitigation options are evaluated using calculations and noise modelling. Effective noise mitigation measures are then integrated into the development’s design phase.

Sound Insulation and Building Envelope

For most buildings, the sound insulation performance is largely dependent on the glazing system. Specific glazing and ventilation systems may be necessary to achieve the desired internal noise criteria. Newly constructed residential developments are required to undergo sound insulation testing in accordance with Approved Document E of the Building Regulations.

Electrical Thermal Imaging Inspections

In recent years, facility management companies have increasingly recognised the importance of electrical infrared inspections for their predictive maintenance programs.

Thermal imaging is vital in electrical predictive maintenance because it identifies potential faults quickly and comprehensively. Unlike spot pyrometers, which require testing individual fuses, thermal imaging captures multiple details in a single image, allowing maintenance teams to perform remedial work before critical asset failures occur.

Electrical Thermal Imaging Inspections are a very cost-effective way of ensuring that your electrical system doesn’t burn out or break down. This is especially important in industries with high voltage systems and/or where continuity of power is critical to the business, e.g. data centres, banks, utility suppliers, manufacturing, hospitals.

The most common benefits are:

• Extension of equipment/building life
• Less plant (critical asset) down time
• Less energy wasted through inefficient operation.
• The ability to prioritise and better target preventive maintenance
• The avoidance of consequential damage to plant or facilities from fires/short circuits

How Will Your Building Benefit from the Survey?

Electrical infrared thermal surveys are incredibly useful for various purposes within new and existing buildings, such as:

1. Saving time & money: by reducing downtime, maintenance costs, and energy consumption.
2. Improving quality and productivity: by optimizing the electrical systems operation and performance.
3. Reducing risk: By identifying potential problems before they cause damage or failure, electrical thermal surveys can prevent costly downtime, repairs, or accidents.
4. Lowering energy costs: By finding poor connections or inefficiencies that waste energy, electrical thermal surveys can help lower annual bills and improve environmental performance.
5. Extending the lifespan of equipment: by improving the serviceability of electrical equipment by preventing premature wear and tear
6. Fulfilling insurance requirements: Some insurance companies may require or recommend electrical thermal surveys as part of their risk assessment or policy compliance.

Introducing Smoke Shaft Testing

Smoke shafts systems are commonly installed as part of a fire-engineered approach to safety in high rise buildings. Smoke shafts are an important element of a smoke control system; therefore, the air tightness performance of the shaft is paramount, so the smoke shaft/s need to pass an air test.

If the smoke shaft doesn’t meet the air tightness target (usually 3.8m3/hr/m2) it can have a negative impact to the overall system and cannot be signed off by the fire system contractor and/or Building Control.

Smoke shafts come in all heights; however, the floor print of the shaft is usually stays the same, approx. 1m x 1.5m. heights however can range from 2 stories to over 20 stories.

Diagnostic Smoke Shaft Test Service
We have a massive amount of experience testing all sizes of smoke shafts, we also offer a diagnostic service where the shaft has failed the smoke shaft air test using both smoke testing and thermal imaging to identify air leakage paths within the smoke shaft envelope. On previous projects where the smoke shaft has failed with massive amounts of air leakage, we have used smoke testing and thermal imagining to identify air leakage paths within the envelope of the smoke shaft.

The findings our smoke shaft surveys are collated into a detailed air leakage report, which then allows the client to undertake targeted remedial sealing works resulting in a test pass during the following visit.

Also, Air Pressure Testing is one of the few companies that is both UKAS and ATTMA Level 2 accredited for undertaking air tightness testing to buildings, as well as specialising in smoke shaft air testing.

If you’ve received a planning condition mandating a plant noise survey in accordance with BS4142, APT Sound Testing is here to assist. Our expertise ensures that industrial noise considerations are thoroughly addressed, helping you navigate the complexities of planning permissions and environmental regulations.

The Growing Importance of Noise Control

Industrial noise is increasingly scrutinized by planning authorities, particularly as the Central Government’s initiatives to redevelop brownfield sites lead to closer proximity between industrial and residential areas. This proximity often raises concerns about noise levels and operating hours affecting the amenity and quality of life for residents.

Local authorities typically regulate noise emissions through planning conditions, requiring effective noise insulation for plant and machinery. Achieving and maintaining sound pressure level limits at site boundaries or nearby sensitive receptors is crucial. Our role involves setting noise level guidelines, ensuring compliance, and recommending mitigation measures when necessary.

Our Methodology

Baseline Noise Assessment

When a new noise source is being introduced to your project, we begin by measuring the existing ambient noise levels in the area over a 24-hour period. This baseline data helps us predict the potential impact of the new noise source. For existing noise sources, we conduct a 24-hour noise measurement with and without the noise source operational to determine its specific impact.

BS4142 Compliance

BS4142 is the standard method for assessing industrial noise in residential areas. It involves measuring the background noise level (LA90) – the level exceeded for 90% of the time – at different times of the day if necessary. Our consultants are well-versed in the procedures and requirements of BS4142, ensuring accurate and reliable assessments.

Detailed Survey and Reporting

We provide comprehensive survey reports that include:

1. Noise Measurement Data: Detailed recordings of noise levels using state-of-the-art Norsonic acoustic equipment.
2. Impact Predictions: Analysis and predictions of the new noise source’s impact based on the baseline data.
3. Mitigation Strategies: Recommendations for noise reduction and insulation measures. These may include noise mapping to visualize the effectiveness of proposed measures in real-life scenarios.

Understanding BS4142 Noise Assessments

Introduction to BS4142

BS4142 is a standard methodology used to assess noise from industrial and commercial premises. The assessment focuses on the impact of noise on people living in nearby residential areas, helping to ensure that industrial activities do not significantly harm residents’ quality of life.

Assessment Procedure

The BS4142 assessment involves several key steps:

1. Background Noise Measurement: This is measured using the LA90 parameter, representing the noise level exceeded 90% of the time over a specified period.
2. Operational Noise Measurement: Noise from the industrial source is measured while it is operational. This may involve on-site measurements or modeling based on operational data.
3. Comparison and Analysis: The operational noise level is compared to the background noise level to determine the impact. Adjustments are made for tonal, impulsive, or intermittent noise characteristics.
4. Rating Level Determination: The operational noise level is adjusted to reflect its characteristics and compared to the background noise level to determine a rating level.
5. Impact Assessment: The difference between the rating level and the background noise level indicates the potential impact. A higher difference typically signifies a greater impact on residential amenity.

Mitigation Measures

When the assessment indicates a significant impact, mitigation measures may be necessary. These measures can include:

• Acoustic Barriers: Installing barriers to block noise paths.
• Enhanced Insulation: Improving the sound insulation of buildings or machinery.
• Operational Adjustments: Changing operational hours or procedures to reduce noise during sensitive times.
• Noise Control Devices: Implementing silencers, mufflers, or other noise-reducing devices on machinery.

Reporting and Compliance

The final report details the findings of the noise assessment and any recommended mitigation measures. This report is crucial for demonstrating compliance with planning conditions and ensuring that industrial activities do not adversely affect local residents.

Benefits of Professional Noise Assessment

• Accurate Data: Professional assessments provide accurate and reliable noise data, essential for making informed decisions.
• Regulatory Approval: Demonstrating compliance with noise regulations can facilitate smoother planning approvals.
• Community Relations: Effective noise management helps maintain good relations with the local community by minimizing disruptions.
• Operational Efficiency: Identifying and addressing noise issues can improve overall operational efficiency and reduce the risk of future complaints or legal issues.
