5.1 Effects of Air Change-Air change often accounts for a significant portion of the heating or air-conditioning load of a building. It also affects the moisture and contaminant balances in the building. Moisture-laden air passing through the building envelope can permit condensation and...
This specification covers the minimum requirements for construction of fiber-reinforced thermoset plastic fans (both centrifugal and axial) and blowers, and provides for a common basis for determining safe operating speeds. The fan housing shall be of laminate construction consisting...
Atraditional mass and energy balance component approach was used to characterize the performance of fixed-airflow series fan-powered terminal units for applications in building simulationprograms. Theapproachincludedd
A mass and energy balance approach was used to characterize the performance of parallel fan-powered terminal units (FPTUs) with fixed airflow for applications in building simulation programs. The approach included developing relevant massandenergy balance equations for each...
This document specifies checks and measurement methods in order to verify the fitness for purpose of installed ventilation systems in dwellings. It can be applied to commissioning of new systems and performance testing of existing systems. It provides choice between simple test methods, when...

Purpose of Document The purpose of this specification is to support the exchange of certain Aeronautical Operational Control (AOC) air-ground and ground-ground messages. These messages are defined in this specification, apart from those defined in ARINC Specification 620, because they have unique...
Preface Air terminal units play an important role in the energy consumption of a building and ultimately the comfort of occupants, both acoustic and thermal. This design guide was created with the goal of producing a best practice guide to aid in the selection of air terminal units by design...
