In this study the performance of a residential demand controlled (DC) extract ventilation system with an air-to-water heat pump was analysed via dynamic simulations. A real life test case was setup to validate results.
36th AIVC - 5th TightVent - 3rd venticool Conference - Madrid, Spain - 23-24 September 2015
The 36th AIVC Conference " Effective ventilation in high performance buildings", was held in Madrid, Spain, 23-24 September 2015. Contains 119 papers and extended summaries.
Residential demand controlled extract ventilation combined with heat recovery via a heat pump | 2015 | English | 10 pp
Demand controlled ventilation (DCV) can reduce the energy use significantly compared to a constant air volume (CAV) system. However, there is still a large uncertainty about the real energy savings and the ventilation efficiency.
Indoor Carbon Dioxide Concentrations in Ventilation and Indoor Air Quality Standards | 2015 | English | 10 pp
Indoor carbon dioxide (CO2) concentrations have played a role in discussions of ventilation and indoor air quality (IAQ) since the 18th century.
Analysis of indoor air quality & thermal comfort parameters in building regulations in 8 member states | 2015 | English | 10 pp
It is estimated that people spend 60-90% of their life in indoor environments. Therefore, it is obvious that indoor air quality (IAQ) and thermal comfort are of highly importance for the health and wellbeing of the population.
Status of the development of the CEN and ISO standards on energy performance of buildings assessment procedures | 2015 | English | 14 pp
The Recast-EPBD1 requires an update of the current (2007/2008) set of CEN-EPB standards. This update work started in 2012 and will result in a new set of CEN-EPB standards.. Where possible this work will be done parallel with ISO.
Recently the international media like in USA, Canada, UK, Denmark, Germany etc. has been discussing the issue of differences between men and women regarding thermal comfort and the preferred room temperature.
How cool roofs interact with PCMs: investigating thermal-energy behavior of a cool roof membrane with paraffin based PCM inclusion | 2015 | English | 2 pp
The effect of Phase Change Materials (PCMs) to optimize indoor thermal comfort conditions and reduce cooling energy requirement when included in envelope components and materials is demonstrated by an extensive scientific literature (Zhou et al.,
Concrete in ventilated facades for natural cooling of buildings. SINHOR project | 2015 | English | 1 pp
The framework in which the SINHOR project takes place is the "Service Contract R + D + i Relating to Competence Scope of the Ministry of Public Works and Housing" with the research project entitled "Analysis of the energy performance of closures c
Local climate change and in particular, the urban heat island, is the more documented phenomenon of climate change.
Impact of the new rite 2013 (regulation on thermal installation) on indoor air quality | 2015 | English | 10 pp
This paper presents a comparison of Indoor Air Quality in several buildings constructed prior to the implementation of the new Spanish regulation on thermal installations (RITE, 2007 modified on 2013) and some new ones that fully accomplish the re
Ventilation tool for improving the usability of ventilation levels related to Spanish regulations | 2015 | English | 7 pp
Choosing the right baseline level of ventilation has a big impact in the calculated energy needs of buildings.
Impact on the formation of mold in the period of summer that indicates change in existing housing ach. Climate zone D1 | 2015 | English | 6 pp
The north of the Iberian Peninsula is characterized by a high level of humidity during the summer.
Energy saving as a consequence of the proposed change in Spanish regulations relating to indoor air quality | 2015 | English | 8 pp
Recently research at the Eduardo Torroja Institute for construction sciences proposes a new wording for the IAQ regulations for dwellings included in the Spanish Building Code.
Energy and IAQ friendly variable ventilation rates, according with the proposed indoor air quality regulations included in the Spanish building code. | 2015 | English | 11 pp
The Spanish Building Code (BC) regulates indoor air quality (IAQ) requirements in dwellings by establishing threshold continuous flow rates according to the occupancy, use of the rooms and their usable area.
Automatic natural ventilation in large spaces: a passive ventilation technology for passive buildings | 2015 | English | 10 pp
For zero and low energy buildings, high-energy efficiency ventilation is very often confused with a complex mechanical ventilation system with heat recovery.
Theoretical and real ventilation heat losses and energy performance in low energy buildings | 2015 | English | 10 pp
Ventilation in low energy refurbished buildings is the cause of a big part of energy losses.
In response to the European Energy Performance Buildings Directive 2010/31/EU and the Energy Efficiency Directive 2012/27/EU, buildings have increasingly become more insulated in order to reduce the heating losses to a minimum.
Ventilative cooling strategies to reduce cooling and ventilation needs in shopping centres | 2015 | English | 11 pp
Because of the customer need of best possible comfort condition and satisfaction, shopping centers are conditioned by means of basic HVAC systems, often without considering the potential of natural ventilation to contribute to air change rate, and
New buildings have to satisfy ever-tightening standards regarding energy efficiency and consumption. This results in higher insulation levels and lower air leakages that reduce heating demands.
