Commercial Aircraft Cabin Air Quality Study (SP96)

AirplaneSpecial Project SP-96 (1262-RP) deals with air quality and passenger/crew reported symptoms in commercial aircraft cabins.  The initial phase of this project dealing with air quality and passenger/crew reported symptoms in commercial aircraft cabins was successfully completed in July 2004.    The second phase of the project will encompass additional testing on two or more airlines.  The work on the second phase started in February 2007 and a third airline was added in October 2009. The final report is expected in early 2012.

Design Manual for District Cooling (SP97)

Special Project SP-97 is an offshoot of existing research project 1262-RP on district heating and cooling systems. The project is funded by Empower (Dubai), and the result will be a design manual on district cooling systems. The targeted completion date was originally early 2010, but that deadline has been extended with publication now targeted in 2012.

Ventilation and Indoor Air Quality in Retail Spaces (SP98)

ASHRAE was awarded a $1.5 million dollars in grant money from the National Institute of Standards and Technology (NIST) in January 2010 to conduct a three –year research project on ventilation and indoor air quality in retail stores.

Through this study, ASHRAE is seeking to improve the energy efficiency of ventilation systems in retail stores while maintaining air quality by establishing a method to determine the relationship between ventilation rates and IAQ, using measured ventilation and pollutant concentration data. Ultimately, the project will establish a methodology for collection of real world ventilation and air quality data.

Existing pollutant and ventilation rate data on which ventilation requirements for retail stores are based come largely from measurements in office buildings. The project will conduct measurements in up to five retail building types such as general merchandise, department, supermarket, and home improvement/hardware.

The completion of the project is targeted or December 2012.

Performance Measurement Best Practices Guide (SP132)

This project - a follow-up document to the Performance Measurements Protocols volume - was published in 2012.

The book provides how-to guidance and case study examples on the best practice application of the protocols defined in Performance Measurement Protocols. The work on this project also provides feedback for possible future revisions of the Performance Measurement Protocols document.

A Project Committee was established in 2010 to prepare this ASHRAE Special Publication.

This project was overseen and coordinated by the Building Performance Metrics Multi-disciplinary Task Group (MTG).


Underfloor Air Distribution Design Guide (SP 124)

A new edition of the ASHRAE Undefloor Air Distribution Design Guide was published in 2013. The recently revised book incorporates new practical design, construction, and operational experiences that have become available since its original publication in 2003. 

The scope of the volume includes guidance on: architectural issues; structural and seismic issues; interfaces with raised access flooring; plenum pressurization, air leakage, and moisture issues; fire and smoke control issues; physical safety and security issues; thermal, lighting, acoustic, vibration, and indoor air quality control; room air diffusion; dynamic thermal loads; system capacities and controllability; testing, adjusting, balancing and commissioning issues; maintenance and operational issues; flexibility and change issues;  and energy and economic issues.
