BUILDING ENVELOPE TESTING WINDOWS

The field testing gives the owner the assurance that the installed windows, doors, and other building envelope components have been built per the contract documents and will perform to meet the industry-standard guidelines set forth by the design. It is best practice to apply pressure testing and thermal testing to the whole building envelope, and water intrusion testing to a sampling of types of transitions at windows and doors.

Quality Assurance Plan and Submittal Review VERTEX’s Building Envelope Services includes field performance testing, which does just that.

Building Science Advisory / Specification.

PCD offers the following Building Science Services for the evaluation and field testing of building envelope products, mock-ups, assemblies in-place, and whole buildings: Systems benefiting from testing include windows/skylights/sloped glazing, doors, storefronts, curtain walls, wall systems, and roofing. We also identify performance issues in existing building envelopes. We offer complete review, analysis, and testing of the building envelope prior to completion of construction which allows early detection and repair of leaking systems, saving you money. For example, reducing air leakage can result in up to 35% heating savings in certain climates. CTL Engineering is an employee-owned, MBE company.

Controlling air and water leakage protects the envelope assemblies from costly damage/deterioration, improves air quality, reduces the load on mechanical systems and reduces energy costs. CTL Engineering is a full service consulting engineering firm, which provides environmental, geotechnical, construction administration & inspection, accident reconstruction, roofing/building envelope, and specialized testing services to the construction industry.

(PHIUS+) 2018 Passive Building Standard requires 0.08 CFM/FT2 at 75 Pa (or 0.06 CFM/FT2 at 50 Pa) for all buildings except those that are non-combustible (i.e., no wood-based framing members or sheet goods, and no wood-based or paper-based insulation, per the guidebook) and over five stories, which are permitted a maximum air leakage rate of 0.11 CFM/FT2 at 75 Pa (or 0.08 CFM/FT2 at 50 Pa).Building Envelope Consulting and Field Testingīuilding performance starts with a properly designed, installed, and functioning building envelope. <0.11 CFM/ft2 = Highest Standard in AirtightnessĪny project with a measured air leakage rate at/under 0.11 CFM75/FT2 would be considered a extraordinarily airtight building. Army Corps of Engineers (USACE) Air Leakage Test Protocol for Building Envelopes (version 3, 2012) specifies a maximum building envelope air leakage rate of 0.25 CFM75/ft2. The US General Services Administration (GSA) P100 Facilities Standards for the Public Buildings Service (2021) references the 2018 IgCC to set a “baseline” level for enclosure airtightness of 0.25 CFM75/ft2. For ultimate quality assurance, site-installed fenestration and curtain wall products must be eld tested for air inltration, water leakage, and structural. The IgCC specifies that the measured air leakage rate of the building envelope shall not exceed 0.25 CFM75/ft2.

BUILDING ENVELOPE TESTING CODE

The 2021 International Green Construction Code (IgCC) requires whole-building pressurization testing in accordance with ASTM E779, ASTM E1827, CAN/CGSB-149.10, CAN/GCSB-149.15, ISO 9972, or equivalent.
