The GK environmental house is the first office building in Norway built according to the passive house concept. In such buildings, it is crucial to develop a ventilation strategy to reduce the energy use outside of the operating time.
35th AIVC - 4th TightVent - 2nd venticool Conference - Poznań, Poland - 24-25 September 2014
The 35th AIVC Conference " Ventilation and airtightness in transforming the building stock to high performance", was held in Poznań, Poland, 24-25 September 2014. Contains 86 papers.
Energy-optimal ventilation strategy outside of the operating time for passive house office buildings in cold climates | 2014 | English
Air heating of passive house office buildings in cold climates – how high supply temperature is acceptable? | 2014 | English
The impact of over-tempered air on the perceived indoor climate was evaluated by questionnaires filled in by the users of the first office building with passive house standard in Norway.
Indoor climate in a Danish kindergarten built according to active house principles: measured thermal comfort and use of electrical light | 2014 | English
The Kindergarten Solhuset is built according to the Active House vision with an emphasize of good daylight conditions and fresh air.
Experiences with ventilative cooling in practical application based on experiences with completed active houses | 2014 | English
The present paper addresses experiences with ventilation and thermal comfort in the Active House concept, based on the Active House Specification and realized Active Houses.
Self-evaluated thermal comfort compared to measured temperatures during summer in three active houses where ventilative cooling is applied | 2014 | English
The thermal comfort of the residential buildings Sunlighthouse in Austria and LichtAktiv Haus in Germany are investigated with a particular focus on the summer situation and the role of solar shading and natural ventilation.
Comparison of two ventilation control strategies in the first Norwegian school with passive house standard | 2014 | English
The Marienlyst School is the first educational building in Norway built according to the passive house standard. This building benefits from a super-insulated and airtight envelope.
An inherent element of the passive house is the system of exhaust ventilation in air supply.
Monitoring of an innovative room-by-room demand controlled heat recovery system on four locations | 2014 | English
Demand controlled heat recovery ventilation systems, which combines heat recovery (HRV) and demand controlled (DCV) is growing fast among ventilation manufacturers.
Heating "passive house" offices in cold climate using only the ventilation system – comparison of two ventilation strategies | 2014 | English
In this article we compare to ventilation strategies to heat a “passive house” office building using only the ventilation system.
Summer performance of residential heat recovery ventilation with an air-to-air heat pump cooling system | 2014 | English
Increasing airtightness and isolation of residential buildings in today’s climates cause challenging situations for the summer indoor climate.
Demand-controlled ventilation. 20 years of in-situ monitoring in the residential field | 2014 | English
Is Demand-controlled ventilation a relevant answer to face the new challenges of the Building sector, which requires everyday higher energy efficiency and better indoor air quality?
Impact of a poor quality of ventilation systems on the energy efficiency for energy-efficient houses | 2014 | English
The “VIA-Qualité” project (2013-2016) focuses on low energy, single-family dwellings. It proposes the development of quality management approaches (ISO 9001) which aim to increase both on-site ventilation and indoor air quality.
PROMEVENT: Improvement of protocols measurements used to characterize ventilation systems performance | 2014 | English
For the coming energy-efficient buildings, the guarantee of energy performance becomes a major challenge. It is therefore crucial to implement accurate and reliable measurements, in order to ensure this performance.
The effect of a cooling jet from ceiling on thermal comfort, perception and subjective performance in warm office environment (29.5 °C) was studied. Altogether, 29 participants (13 male and 16 female) participated.
Central ventilation systems with heat recovery have shown their limits especially within the context of building energy retrofit.
The indoor climate in residential buildings is affected by the people that live in the house and their activities. One of the goals of a ventilation system is to prevent excess humidity in the house by removing part of the moisture.
Measurements were performed in a test room at SINTEF building and infrastructure, Oslo.
Monitoring results and optimization of a façade integrated ventilation concept for building retrofit | 2014 | English
An office building of the Fraunhofer Institute for Solar Energy systems (Fraunhofer ISE) in Freiburg was retrofitted in 2012 with an innovative concept based on technology integration in the façade.
Requirements and hand-over documentation for energy-optimal demand-controlled ventilation | 2014 | English
Demand controlled ventilation (DCV) considerably reduce the ventilation airflow rates and energy use compared to Constant Air Volume (CAV) systems. DCV in commercial buildings is probably a prerequisite to achieve ambitious energy-goal.
Demand controlled ventilation in renovated buildings with reuse of existing ductwork | 2014 | English
Most existing non-residential buildings have Constant Air Volume (CAV) ventilation leading to over-ventilation in periods with low or no occupancy.
