This paper reports an investigation into the ability of the air supply in non-unidirectional cleanrooms to aid recovery from episodes of airborne contamination, and minimise airborne contamination at important locations. The ISO 14644-3 (2005) recovery test, which measures the rate of decay of test particles, was assessed and a reinterpretation of the test results suggested. This allowed air change effectiveness indices to be calculated and used to evaluate the ventilation effectiveness of the cleanroom’s air supply.

Mr.Platts briefly reviews current Canadian housing and the potential for controlled ventilation with exhaust air heat recovery. Discusses cost effectiveness of exhaust air heat recovery and suggests that payback periods are generally too long and hence uneconomic. Mr.Bonnyman discusses the market for domestic heat recovery units. Briefly reviews the types of heat recovery equipment. Gives product information for units available in Canada.
The QUALICHeCK-TightVent webinar: “Building airtightness and initiatives to improve the quality of the works” will be held on Tuesday 12 January, 10:00-11:30 (Brussels time). The objective of this webinar is to give background information on selected initiatives to improve the quality of the works with respect to building airtightness.
The programme includes 4 presentations of 15 minutes as follows:
The principal objective of this webinar series is to give the status, needs, and perspectives on developments to consider ventilative cooling in energy performance assessment methods in several countries. This first webinar will focus on the developments in Austria, Denmark and France.
The 2016 AIVC conference will be organised in collaboration with ASHRAE. It will be held in the Crowne Plaza hotel in Alexandria (10 km from Washington DC) on September 12-14, 2016.
The Conference title is “ IAQ 2016 – Defining Indoor Air Quality: Policy, Standards and Best Practices.”
Contributions are invited on the following themes and topics among others:
Around 160 participants attended the joint 36th AIVC - 5th TightVent – 3rd venticool conference held in Madrid, Spain September 23-24, 2015. The programme consisted of 3 parallel sessions with contributions from 27 countries and international organisations.
Over 120 presentations were given covering topics ranging from ventilative cooling and thermal comfort, ventilation in relation to IAQ and health, air infiltration through leaks in the building envelope and ductwork.
We are very pleased to welcome the UK as new AIVC country.
This is a positive signal showing the relevance of the AIVC to support research and international collaboration on ventilation and air infiltration in buildings. This is also confirmed by the number of papers that will be presented at the AIVC Conference in Madrid on September 23-24, and the diversity of the countries represented (92 papers, 23 countries). With various topical sessions, this conference will also help disseminating specific projects results and cross-fertilising ideas between these projects.
The venticool platform paper: “Overview of provisions for ventilative cooling within 8 European building energy performance regulations” is now available online. This study aimed to focus on regulatory measures taken or missing regarding ventilative cooling in several countries, which could either inspire developments in other countries or point out specific problems for the market uptake of this technology.
