IEA-EBC annex 68 - Design and Operational Strategies for High IAQ in Low Energy Buildings

A collection of reports, journal & conference papers developed by IEA-EBC annex 68 "Design and Operational Strategies for High IAQ in Low Energy Buildings".


It is a widely spread misunderstanding that highly insulated buildings perform poorly with respect to theindoor environment.


Air-conditioning, the powerful indoor-climate control system, is becoming widespread throughout theworld. As the dissemination accelerates, building design itself is changing drastically, and buildings arebeing designed to adapt to air-conditioning. This kind of change can be regarded as an evolution ofbuilding design; on the other hand, energy consumption in buildings has been increasing drastically.Today, more than one third of the global warming gas emissions in Japan are considered to come fromthe building sector.

Valutazione technico economica di un intervento di riprogettazione energetica basato sullo standard passivhaus

Il concetto di sviluppo sostenibile rappresenta oggi il punto di partenza per nuove strategie progettuali fondate su target energetici e di qualità ambientale, soprattutto nei nuovi edifici. Scopo del lavoro è quello di analizzare le prestazioni del siste

Shattering the energy barrier.

Describes how methods used in widespread energy efficient residential buildings in Germany are now being applied to larger buildings. Germany's Passiv Haus Institut has become a leading centre in developing a specification for the next generation of energy efficient buildings - the Passive House Standard. In 400 residential building the standard has reduced total energy consumption to 12% of the UK norm. Describes how this approach has been applied to a 2,200 m2 office and factory in Colbe, Marburg. The three-storey structure was completed in autumn 1998.

Lord of the files.

Nearly 20 years after it was ordered by Parliament, the f'.230 million parliamentary building is ready to welcome its inmates: 200-odd constituency MPs and their staff. Does the building's controversial luxury extend to the engineering services?

The role of simplified ventilation modeling for the application of low energy design: a library case study.

This paper discusses how simplified thermal and ventilation tools could be used during thefeasibility study of buildings to demonstrate the advantages of natural and low energyventilation strategies. The paper focuses on local authority library buildings in South-EastEngland and two simplified tools were used; one using a dynamic thermal simulation andventilation method and another based on the admittance method. The prediction of both toolswere compared with measured temperatures from an existing library that has a knownoverheating problem.

Low energy urban housing: six European Union demonstration projects.

The SUNH and SHINE European Commission THERMIE 1996 Targeted Projects aim to demonstrate for European urban housing sector the relevance of a serie of innovative technologies (applied on 10 new 1;onstructions within SUNH and 6 retrofrtting projects within SHINE) to reduce C02 emissions through the implementation of different RUE & RES techniques. After the general presentation of SUNH and SHINE made during the PLEA conference of Lisbon, this paper aims to give a detailed presentation of the most advanced projects using slides and video.
