ISO/NP 7615-2

Energy performance of building systems — Underfloor air distribution systems — Part 2: In-situ measurement of room air stratification

Scope

The proposed standard is the second part of a comprehensive series of international standards related to energy performance of underfloor air distribution systems. This standard shall stipulate in-situ measurement method of air stratification, a critical feature of UFAD system which is not covered by previous works.
The new series of ISO standards will be composed of multiple parts as follows (tentatively).
-
Part 1: General overview (under publication)
Part 2: In-situ measurement of room air stratification
Part 3: In-situ measurement of thermal decay
Part 4: Determination of air permeability of underfloor plenum

This standard does not cover the conventional displacement ventilation system.
