TN 67: Building airtightness: a critical review of testing, reporting and quality schemes in 10 countries

This report gives a critical review of steps taken in 10 countries (Belgium, Denmark, Finland, France, Germany, Netherlands, Japan, Sweden, UK, USA) with regard to testing and reporting schemes as well as overall quality approaches to improve building airtightness. The analyses are mostly based on contributions and discussions with 20 speakers invited to the AIVC-TightVent airtightness international workshop held in Brussels, 28-29 March 2012; they also include information from earlier publications as well as from the authors’ experience.

TN 66: Building air leakage databases in energy conservation policies: analysis of selected initiatives in 4 European countries and the USA

We collected information on existing envelope air leakage databases from countries that are involved in the AIVC-TightVent project “Development and applications of building air leakage databases”. This document summarizes the information from five countries: Czech Republic, France, Germany, UK, and USA. Even though our summary is not exhaustive of all existing data on whole-building envelope air leakage, it provides an overview of recent efforts from a number of countries. There are many reasons why different countries are collecting these data.

TN 65: Recommendations on Specific Fan Power and Fan System Efficiency

Energy use for fan operation can be significantly reduced by a 3-flanked approach: 

(1) The first step is prudent sizing of ventilation rates by minimizing the demand (e.g. low-emission building materials, passive cooling design), and by utilizing efficient air distribution. The latter reduces unnecessary over-ventilation by use of airtight ductwork, careful choice of room airflow principles (i.e. minimizing short-circuiting), and controls for demand-control of flow rate.
