The joint 38th AIVC, 6th TightVent and 4th venticool Conference on ‘Ventilating Healthy Low-energy Buildings' was held in Nottingham, UK, 13-14 September 2017. The programme consisted of plenary sessions and 3 parallel tracks, one devoted to Ventilative Cooling in four sessions (20 papers) and 17 papers in poster sessions. Two sessions were topical, proposed by IEA EBC Annex 62, plus one discussion session. One topical session focused on case-studies [6, 18, 23-25] including houses, offices, a large space and shopping malls.
The airtightness track at the AIVC 2017 conference consisted of 23 presentations organised in 5 sessions of which 3 were topical sessions with a number of invited presentations. Most of the airtightness topics in the call for papers for the conference were represented in the papers in the airtightness track:
The International Energy Agency's Energy in Buildings and Communities (IEA-EBC) Programme newsletter of November 2017 (Issue 66) has been released. The current edition includes an introduction of Canadian policies and movements, also with updates on EBC’s major R&D projects that cover ways to realise both better indoor air quality and higher energy efficiency, reconsideration of thermal comfort by using energy more wisely, and analysis of real energy use and relevant factors by using big data.
The evaluation questionnaire of the 38th AIVC conference: “Ventilating healthy low-energy buildings” held in Nottingham-UK on September 13-14, 2017, was sent out to 170 attendees of the event. A summary of the results with feedback from 90 of the participants is now available here.
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.
