AIVC is one of the founding members of the Indoor Environmental Quality Global Alliance (www.ieq-ga.net).

ASHRAE has developed proactive guidance to help address coronavirus disease 2019 (COVID-19) concerns with respect to the operation and maintenance of heating, ventilating and air-conditioning systems.  More information can be found on: https://www.ashrae.org/about/news/2020/ashrae-resources-available-to-address-covid-19-concerns

We are pleased to announce the release of AIVC Contributed Report 18: Ventilation and Indoor Air Quality in New California Homes with Gas Appliances and Mechanical Ventilation!

The “ASHRAE HVAC Duct Sizer” application designed by Carmel Software Corporation for ASHRAE, allows the user to quickly size one HVAC duct run or a range of duct sizes using the constant friction method.

In the "Size by Airflow" mode, the user can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensions and the calculated velocity and friction loss.

The Building America program is organizing the webinar:"Score with Indoor Air Quality", to be held on Wednesday, September 28, 2016 9:00 PM - 10:30 PM CEST. In this event, Dr. Brett Singer, from the Lawrence Berkeley National Laboratory, will present on the development of an indoor air quality (IAQ) scoring system and the planned elements of a national new home study. 

The conference, co-organized by ASHRAE and AIVC, takes place Sept. 12-14, 2016, in Alexandria, Va., at the Crowne Plaza Old Town Alexandria.

This book, released by the Energy Performance Measurement Institute, provides significant information on worldwide energy use and residential sector energy use, including many factors that are unique to the residential sector. Energy performance measurement methods and data are presented. Simplification of residential sector energy performance measurement is a key theme. 

The abstract submission deadline for the 37th AIVC - ASHRAE - IAQ joint Conference “Defining Indoor Air Quality: Policy, Standards and Best Practices” has been extended. The extended deadline for abstract submission is now December 14, 2015.
