Certification of BlowerDoor test in Denmark

Purpose of the work

Since the introduction of the Blower Door test to the building code in Denmark back in 2006, there has been a move toward encouraging the sector to raise the quality level of tests performed around the country. The building code requirements in Denmark are:

New framework for reliable pressurization tests of buildings in Belgium

Purpose of the work

In Belgium, airtightness of buildings is taken into account in the regional Energy Performance of Buildings (EPB) regulations. When measured, it can be used in the calculation in place of a default unfavourable value and therefore improve the calculated performance.

Does each hole mean damage? Vapor convection and the law of physics

Purpose of the work

Condensation risks in wooden building components are mainly caused by water vapor penetrating the cross section of the component through airflow. Even small pressure differentials result in a lot more vapor flowing through a joint of only a few millimeters than that which would migrate by diffusion through many more undisturbed square meters of area.

Minimum requirements for adhesive joints ‒ DIN 4108 part 11

Background

Based on an application for standardization by the company ISOVER in October 2007, the German Industrial Standard DIN 4108 – 11 has been cleared by the responsible bodies in DIN for review by the committee NA005-56-93AA, “Airtightness”. The work on the details of the standard has been going on for seven and a half years now. The standard will be entitled “Thermal Insulation and Energy Savings in Buildings – Part 11: Minimum Requirements for the Durability of Adhesive Joints with Adhesive Tape and Adhesive Compounds for Use in Airtight Layers”.

CR19: Indoor Air Quality Design and Control in Low-Energy Residential Buildings - EBC Annex 68 | Subtask 4: Current challenges, selected case studies and innovative solutions covering indoor air quality, ventilation design and control in residences

The objective of Subtask 4 in the IEA EBC Annec 68 was to integrate knowledge and results from remaining Subtasks and present them in the context with current knowledge. The focus of the Subtask 4 was on practitioners dealing with ensuring high Indoor Air Quality (IAQ) in modern low-energy residences, the demands and challenges they meet during daily work. This especially includes architects and ventilation designers, facility managers, property developers and employees of public authorities. This publication is a result of Subtask 4’s work.

Metal Oxide Semiconductor sensors to measure Volatile Organic Compounds for ventilation control

The application of Metal Oxide Semiconductor (MOS) sensors measuring Volatile Organic Compounds (VOC) gains increasing attention in the ventilation community because of their low price and claimed ability to supplement or even substitute CO2 sensors for demand controlled ventilation (DCV). Even though there are many “Indoor Environmental Quality” meters available on the market, in which these sensors are used, the amount of scientific studies focused on their reliability and applicability is still limited.

VIP 40: Ductwork airtightness - A review

Ventilation Information Paper no40 "Ductwork airtightness - A review", aims to complement Ventilation Information Paper VIP 01 “Airtightness of ventilation ducts”. It provides a literature review of the work performed since 2003 in the field of ductwork airtightness. Its objectives are to provide information on:
