A study of panel ridges effect on heat transfer and pressure drop in a ventilation duct | 2017 | English | 10 pp
The effect of adjustable cooling jet on thermal comfort and perception in warm office environment – a laboratory study | 2017 | English | 7 pp
The aim was to study how the cooling jet from the ceiling, with individual control over the airflow, is perceived and how it affects the thermal comfort in warm office environment.
From EN 779 to ISO 16890: a new worldwide reference test method for general ventilation filters | 2017 | English | 6 pp
For testing of general ventilation filters, a completely new standard is now available and is going to replace EN 779 (2012) since the parts 1 to 4 of ISO 16890 (2017) have been adopted in August 2016 and published in 2017 at both international an
Mixed-mode ventilative cooling opportunity for an existing shopping mall retrofit | 2017 | English | 10 pp
Shopping centres currently design has included a small portion of automated windows sized for smoke ventilation. Their presence is mandatory for fire regulation and they are usually operated just in case of fire.
Natural Pressure Differential – Infiltration Through Wind Results of a Long-Term Measurement | 2017 | English | 12 pp
Wind pressure and thermal forces are driving forces for pressure difference on the building envelope.
Natural ventilation systems in Mediterranean schools. A prototype experience in Andalusia as an alternative to mechanical ventilation | 2017 | English | 12 pp
In high density occupation rooms, it is necessary to control indoor air quality (IAQ) combined with other comfort parameters. An adequate IAQ in classrooms enhances children learning and academic results are improved.
Numerical analysis of thermal comfort in Near-Zero Energy Buildings (NZEB) with light radiant ceilings and diffuse ventilation | 2017 | English | 9 pp
Renewable energy sources for heating and cooling buildings usually have temperatures close to room temperature and therefore a limited convertibility potential, i.e. they are of low value.
Contaminant stratification in displacement ventilated spaces - a two zone model approach. Model prediction compared to experimental data | 2017 | English | 9 pp
Displacement ventilation (DV) is an alternative to conventional mixing ventilation in various types of rooms.
Assessing Occupant and Outdoor Air Impacts on Indoor Air Quality in New California Homes | 2017 | English | 10 pp
In 2008 the State of California adopted new building codes that required the use of mechanical ventilation systems in homes that meet the requirements of ASHRAE Standard 62.2.
A key aspect of achieving acceptable indoor air quality is source control. Cooking has been recognized as a significant source of pollutants for health impacts (e.g., PM2.5 and NO2) as well as moisture and odour.
Component leakage: potential improvement graphs and classification of airpaths | 2017 | English | 7 pp
Last years, interest in airtightness increases among all construction fields and airtightness becomes a major issue in the reduction of energy consumption in buildings.
Study of variants to classical mechanical exhaust ventilation systems by using mechanical exhaust in habitable rooms | 2017 | English | 6 pp
Nowadays, due to the higher energy performance of dwellings, ventilation plays an increasing role in maintaining a good indoor comfort.
Coupling night ventilative and active cooling to reduce energy use in supermarkets with high refrigeration loads | 2017 | English | 10 pp
Night ventilation is used extensively as a low energy strategy to cool buildings in climates where night temperatures are suitable.
A “heat recovery hybrid ventilation system” is the combination of passive stack ventilation and mechanical push-pull ventilation. Two heat storage boxes are connected to the natural EA stack and the underfloor natural OA duct.
Development of protocol for sub-metering for ventilation models and verification for shopping centres | 2017 | English | 10 pp
Shopping centres are complex buildings with specific needs. The use that different areas are put to affects energy consumption, whereas the different functional patterns and stakeholder groups influence energy use.
About 1,000 ductwork airtightness measurements performed in new French buildings: database creation and first analyses | 2017 | English | 9 pp
In France, the current regulation on the energy performance of buildings (RT 2012) does not require ductwork airtightness measurement when the default-value is used in the regulatory EP-calculation.
Façade Improvements to Avoid Draught in Cold Climates – Laboratory Measurements | 2017 | English | 10 pp
With the goal of increasing building flexibility and reducing energy use, yet ensuring IAQ, the feasibility of natural ventilation in a building in Oslo is studied.
