Façades account for almost 50% of the thermal load in buildings in the tropics and are related to many occupant comfort issues, such as visual comfort and thermal comfort. SERIS operates a well-equipped laboratory for testing of thermal and optical properties of building façade materials and assemblies, conducted according to the ASTM C1199, C1363, C1371, NFRC 300-2010, NFRC 301-2010 and DIN-5036-3 standards.
The laboratory provides the following services:
In the area of façade technologies, our services for industry partners and opportunities for collaborative research include:
In energy audits, the so-called “blower door” tests are used to determine a building’s air-tightness. Reasons for establishing a proper building air-tightness include:
In this test, a blower door with one or two powerful fans temporarily replaces an actual door of the building under test. The fan pulls air out of, or blows air into, the building, thereby lowering or increasing the air pressure inside. Airflow through existing gaps in the building will be induced due to the pressure differences. In combination with the use of a smoke pencil, air leaks can easily be detected. These tests measure the air infiltration rate of a building. They can also be used to measure airflows between building zones, to test ductwork air-tightness, and to localise air leakage sites in a building envelope. The blower door test is conducted according to the ASTM E-779, ATTMA and BS EN 13829:2001 standards.
