RISASHRAE APPLICATION SI CH 19: DATA PROCESSING AND TELECOMMUNICATION FACILITIES
Abstract: Overview
Environmental requirements of datacom equipment vary depending on the type of equipment and/or manufacturer. However, a consortium of server manufacturers has agreed on a set of four standardized conditions (Classes 1 to 4), listed in Thermal Guidelines for Data Processing Environments (ASHRAE 2008). A fifth classifica...

ASHRAE OR-10-018: ASHRAE Standard 90.1 Metal Building U-Factors—Part 2: A Systems Based Approach for Predicting the Thermal Performance of Single Layer Fiberglass Batt Insulation Assemblies
Abstract: INTRODUCTION
During the late 1990's, the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) Standing Standard Project Committee (SSPC) 90.1 Envelope Subcommittee incorporated specific maximum allowable Ufactors (the overall heat transfer coefficients) for metal building roofs and walls into ANSI/...

ASHRAE LO-09-049: Comfort, Energy Consumption, and Economics of a School with Energy Recovery
Abstract: ABSTRACT
Energy wheels are often used to reduce energy consumption and HVAC equipment capacities in buildings, but the effect of the energy wheel on the indoor comfort conditions has not been studied in detail. The addition of an energy wheel to the HVAC system may improve the indoor air relative humidity and perceived air qual...
