Critical steps for a wide scale implementation of building and ductwork airtightness

This ebook, produced by TightVent Europe, includes a number of publications from the Intelligent Energy Europe programme and its predecessor, namely from the ASIEPI project, SAVE-AIRWAYS, and SAVE-DUCT projects.

Building and ductwork airtightness: Selected papers from the REHVA special journal issue on ‘airtightness’

The 2002 Energy Performance of Buildings Directive (EPBD) already indicated the potential importance of airtightness. With the 2010 EPBD recast and its ambitious 2020 targets, there is even more pressure on these aspects since for most European climates and countries, good envelope and ductwork airtightness levels are necessary to achieve nearly zero-energy buildings.

Ventilative Cooling. State-of-The-Art Review

This report summarizes the work of the initial working phase of IEA ECB Annex 62 Ventilative Cooling and is based on the findings in the participating countries. The report is an official Annex report that describes the state-of-the-art ventilative cooling potentials and limitations, its consideration in current energy performance regulations, available building components and control strategies and analysis methods and tools.

Status and recommendations for better implementation of ventilative cooling in standards, legislation and compliance tools

This summary report presents insights on recommendations into how ventilative cooling is integrated in EN standards, ISO standards, national standards, national legislation and national compliance tools. The information presented derives from feedback by IEA EBC Annex 62 experts of 11 countries (see Table 1) who have completed a questionnaire. This gives a high level of insight into the current status, and thereby the recommendations to be given on the basis of this knowledge.

Ventilative cooling source book

Overheating in buildings is an emerging challenge at the design stage and during operation. This is due to a number of reasons including high performance standards to reduce heating demand by high insulation levels and restriction of infiltration in heating dominated climatic regions; the occurrence of higher external temperatures during the cooling season due to changing climate and urban climate not usually considered at the design stage; and changes in internal heat gains during operation are not factored in the design.

Ventilative cooling case studies

Examples of well documented case studies that use ventilative cooling (VC) to reduce the energy demand for cooling or overheating risk in new and refurbished buildings are valuable to the energy in buildings community. This report and associated brochures contains such examples and provides details on the design, control, operation and performance of the VC systems. The report aggregates and summarises all 15 case study buildings collected in subtask C of IEAEBC Annex 62. 

Ventilative cooling design guide

This design guide is based on the work of IEA-EBC Annex 62 “Ventilative Cooling” and the research findings of the participating countries.

This guide is designed for both architects and engineers to support the design of ventilative cooling systems especially in the early design stages.

Status and recommendations for better implementation of ventilative cooling in standards, legislation and compliance tools (Background report)

This background report presents insights on recommendations into how ventilative cooling is integrated in EN standards, ISO standards, national standards, national legislation and national compliance tools. The information presented derives from feedback by IEA EBC Annex 62 experts of 11 countries who have completed a questionnaire. This gives a high level of insight into the current status, and thereby the recommendations to be given on the basis of this knowledge.

Ventilative cooling. State-of-the-art review executive summary

This report summarises the outcome of the work of the initial working phase of IEA ECB Annex 62 Ventilative Cooling and is based on the findings in the participating countries. It presents a summary of the first official Annex 62 report that describes the state-of-theart of ventilative cooling potentials and limitations, its consideration in current energy performance regulations, available building components and control strategies and analysis methods and tools.
