Blower door tests of a group of identical flats in a new student accommodation in the arctic

A new student accommodation for engineering students “Apisseq” was built in the town of Sisimiut, Greenland in 2010. Its purpose is not only to provide accommodation for students. Thanks to its complex monitoring system it enables researchers to evaluate the building’s energy performance and indoor air quality (IAQ) as well as performance of some single components. In summer 2012 a blower door test was performed on all 37 living units out of which 33 are identical single room flats and 4 are larger double room flats.

Improvement of summer comfort by passive cooling with increased ventilation and night cooling

The present study describes the potential improvement of summer comfort and reduction of energy consumption that can be achieved by adopting passive cooling solutions, such as daytime comfort ventilation with increased air velocities and night cooling, in domestic buildings. By means of the IDA ICE based software EIC Visualizer, the performances of ten ventilation and cooling strategies have been tested in four different climatic zones across Europe (Athens, Rome, Berlin and Copenhagen).

Update of the spanish regulation regarding ventilation and infiltration: analysis, comparisons and repercussions

The Spanish Technical Building Code is one of the three royal decrees that were approved in Spain as a consequence of the transposition of the European Directive on the energy performance of buildings (2002/91/EU) [1]. One basic document of the Technical Building Code deals with the limitations in the energy demand of buildings. Nowadays, due to the recast of the European Directive on the energy performance of buildings (2010/31/EU) [2], a revision process of the current regulations has begun, starting with the Technical Building Code, with its first revision envisaged for 2012.

Strategies for controlling thermal comfort in a Danish low energy building: System configuration and results from 2 years of measurements

The thermal comfort of the residential building Home for Life is investigated with a particular focus on the strategies used to achieve good thermal comfort, and the role of solar shading and natural ventilation. Home for Life was completed in 2009 as one of six buildings in the Model Home 2020 project. It has very generous daylight conditions, and is designed to be energy neutral with a good indoor environment.

The Influence of Surrounding Buildings on the Natural Ventilation Performance of Residential Dwellings in Hong Kong

Natural ventilation in residential dwellings is very important for occupants’ health and comfort. Previous studies by the authors have concluded that natural ventilation performance in dwellings can be enhanced by positioning the two groups of window openings (bedroom windows and living room windows) in opposite directions or perpendicular to each other; and/or the use of side-hung windows. However, the buildings selected for those studies were located in an isolated site, for the purpose of focused evaluation of the influence of various configuration parameters and window types.

Analysis and Repercussions of the Updating of the Spanish Regulation Regarding Ventilation and Infiltration

The Spanish Technical Building Code is one of the three royal decrees that were approved in Spain as a consequence of the transposition of the European Directive on the energy performance of buildings (2002/91/EU, 2002). One basic document of the Technical Building Code deals with the limitations of building energy demands. Nowadays, due to the recast of the European Directive on the energy performance of buildings (2010/31/EU, 2010), a revision process of the current regulations has begun, starting with the Technical Building Code, with its first revision envisaged for 2012.

Evaluating the Influence of Window Types on the Natural Ventilation Performance of Residential Buildings in Hong Kong

Unlike cold climate regions, where natural ventilation is not preferred during winter, natural ventilation is always preferred in Hong Kong for cooling because of the subtropical climate. It also provides better indoor environment quality and energy conservation. Natural ventilation performance of a residential unit is affected by internal as well as external factors. External factors are often subject to constraints beyond the control of site planners and architects.

A review of evidence linking ventilation rates in dwellings and respiratory health - A focus on house dust mites and mould

This paper reviews the literature for evidence of links between ventilation rates in dwellings and moisture related respiratory health with a particular focus on house dust mites (HDM) and fungal growth. There is general consensus that a link exists between ventilation rates in dwellings and respiratory hazards (for example HDM). There is also general consensus of a link between these respiratory hazards and respiratory problems, but it is not clear to what extent hazards cause ill-health.

Control of the Ep-Regulation in 3 French Regions: Approach and Preliminary Results on 29 Buildings

This paper focuses on energy performance compliance checks to the French EP-regulation RT 2000 and the way they are performed in Rhône-Alpes, Burgundy, and Franche-Comté. It gives an overview of the approach developed and used which consists in collecting

ENERGY AUDITS IN DWELLING BUILDINGS IN LATVIA. DATA ANALYSIS

Experience of energy auditing of residential buildings in Latvia discovers problems with discrepancy of data measured and calculated. Analysis of dynamic changes of data presents factors, which influence results of energy audits and proposals for energy efficiency measure. Paper presents analysis of influence of solar radiation and modelling of solar factor for control of heat supply.
