1 June 2021, Webinar – Resilient Ventilative Cooling in practice

Submitted by on Wed, 03/17/2021 - 12:25

The current development in building energy efficiency towards nZEB buildings represents a number of new challenges to design and construction. One of these major challenges is the increased need for cooling in these highly insulated and airtight buildings, which is not only present in the summer period but also in the shoulder seasons and in offices even in midwinter. Resilient ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.

VIP 41: Impact of wind on the airtightness test results

Submitted by on Tue, 03/16/2021 - 12:03

Building airtightness tests have become very common in several countries, either to comply with minimum requirements of regulations or programmes, or to justify input values in calculation methods. With more widespread use it has become increasingly important to understand and quantify the reliability of these tests.

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

Submitted by on Tue, 01/05/2021 - 10:05

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.

VIP 40: Ductwork airtightness - A review

Submitted by on Mon, 04/06/2020 - 16:25

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:

 

VIP 37: Impact of Energy Policies on Building and Ductwork Airtightness

Submitted by on Wed, 09/06/2017 - 17:22

This Ventilation Information Paper analyses both the policy instruments used (regulatory requirements and incentives, specific programme requirements, quality frameworks for testers and builders) and the changes observed in practice in terms of building and ductwork airtightness over the past 5 years, using as reference mostly publications from AIVC and TightVent led events. Although we have not restricted our literature review to specific parts of the world, the majority of the publications we found come from Europe and the USA.
