Building Envelope Commissioning
BECx (sometimes referred to as building enclosure commissioning) is a quality-based process for evaluating the performance of a facility envelope to determine if a project is meeting the defined objectives, standards, and requirements of the owner.
BECx is especially critical when it comes to measuring energy performance. LEED v4 allows 2 points when the building envelope is included in the commissioning process activities and follows NIBS Guideline 3-2006 used in conjunction with ASHRAE Guideline 0-2005.
Air Infiltration Test
Whole building envelope is tested as per ASTM E779-03 or CIBSE standard TM 23. This test is applicable for Commercial and Residential buildings following LEED from USGBC and Estidama.
We have inhouse HERS (Home Energy Rating System) Rater and ATTMA (Air Tightness Testing & Measurement Association) Level 2 certified Engineer.
Curtain Wall Air Permeability Test
We conduct air permeability test of doors and windows as per ASTM E783 / BS EN12153-2000.
The test is carried out by our engineer with in-house calibrated equipment as per the Project specification in full compliance with AAMA 502
Water Penetration Test
We conduct water penetration test as per ASTM E 1105 / BS EN 1027-2016. The test are conducted by our in house engineer as per the project specification and in compliance with AAMA 502
Smoke Test
In order to find out the leakage in the building, smoke test can be done using smoke generator.
Thermal Imaging
A thermal imaging survey with an infrared camera can be a helpful tool for a variety of purposes including energy auditing, water intrusion, and structural analysis. As such, a forensic investigation is needed to confirm what is revealed from these images.
We have Thermal Imaging Level 2 Certified Engineers inhouse.

- U-Value Measurement
U-value is the term used to describe the heat transfer coefficient of a building element (e.g. of a wall). The U-value describes the insulation quality of a building. The unit of the U-value is W/(m²K). The lower a U-value, the better the insulation quality of the building element.
U-Value approach is standardized in ISO 9869, ASTM C1046 and ASTM C1155. This is the only method which delivers reliable quantitative in-situ information about a building envelope.
Pipe Stress Analysis
Pipe stress analysis is an analytical method to determine how a piping system behaves based on its material, pressure, temperature, fluid, and support. A pipe stress analysis (thermal flexibility analysis) predicts stresses in piping and loads on equipment resulting from thermal gradients, thermal transients, weights, pressure, and bolt-up strain. This study is typically required for piping that experiences high temperature fluctuations, or for long pipe runs such as hot piping to coolers or headers. Cases where equipment is sensitive to external loads may also require a pipe stress analysis.
