AIR TEST

Air Pressurisation Testing

Building Sciences has experience of over 3,000 air leakage pressurisation tests ranging from 1m² specialist enclosures to 60,000m² commercial developments.

These tests measure the extent of air leakage within new or existing envelope assemblies. Pressurisation testing can cover whole buildings, specialist enclosures, floor voids and components (e.g. doors, windows etc).

Components Testing

Components such as doors, windows, blockwork, cladding systems, etc. can be tested in specialist sample chambers either on- or off-site to establish overall air leakage rates / leakage per m² / leakage per linear meter of junction, etc.

Specialist Enclosure Testing

Specialist enclosures such as computer rooms, switch rooms, floor voids, clean rooms, etc. which need low levels or residual air leakage because of processes occurring within the enclosure or within their environmental / protection systems can be tested. Areas of residual leakage can be identified to enable remedial sealing to be undertaken should this be deemed necessary.

Whole Building Testing

Whole-building pressurisation tests can be undertaken to establish envelope leakage rates for comparison against Clients Specification or Building Regulation Part L2 standards. Building Sciences are a UKAS accredited testing laboratory (No. 2546) for testing in accordance with CIBSE TM23 – Testing Buildings for Air Leakage and BS EN 13829:2001 Thermal performance of buildings – Determination of air permeability of buildings – Fan pressurization method.

We are also founder members of

ATTMA - the Air Tightness Testing and Measurement Association

Residual leakage within a building can be identified after a test so that remedial sealing can be undertaken if required.

Indoor Air Quality

• Tracer gas tests to determine outdoor air exchange, ventilation performance and air flow paths.
• Carbon Dioxide level measurement to determine pollutant levels.
• Internal temperature and humidity monitoring.
• On-site meteorological monitoring for spaces with natural or partially natural ventilation.

Differential Pressure Monitoring

Data collection of differential pressures between varying zones (e.g. inside/outside, different floors within a building, etc) Data can be logged for manual or remote downloading where appropriate.
