Revising the ASHRAE 62 ventilation standard.

                    

Standards for heating energy use in Russian buildings: a review and a report of recent progress.

A knowledge of Russian building thermal-energy codes in effect in the post-World War II era is necessary for estimating the performance of the existing building stock, quantifying the impact of energy conservation retrofits, and estimating the benefits of more stringent codes. This paper begins with a thorough review of the prescriptive-based national codes that applied to heated buildings constructed in the Soviet era. The codes defined all envelope thermal performance requirements for space heating.

Test standards for air filtration.

Concerns surrounding indoor air quality in commercial buildings have focused attention on the need for stringent filter performance testing. The Cl BSE engineer should be aware of several test standards

Field comparison of design and diagnostic pathways for duct efficiency evaluation.

A new method of test for residential thermal distribution efficiency is currently being developed under the auspices of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). This test method will have three main approaches, or "pathways," designated Design, Diagnostic, and Research. The Design Pathway uses builder's information to predict thermal distribution efficiency in new construction.
