Special Issue Information

Dear Colleagues,

Thermal comfort and Indoor Air Quality (IAQ) issues have gained significant interest in the scientific and technical community involved in buildings performance analysis and not only. The reasons are related to the fact that people spend much of their time indoors, while indoor environment is affected by external sources (atmospheric pollution) and internal ones (emissions by indoor activities or building materials), also entailing the difficulty to achieve and sustain a thermally acceptable indoor environment, due to the widespread problem of energy poverty. Acoustic and visual comfort issues are also of importance; the term Indoor Environmental Quality (IEQ) aims at including all the above parameters. The inability to regulate these parameters, not only leads to discomfort and potential productivity loss for humans, but it is also connected to health deterioration.

This special issue should include works discussing the above aspects, with some emphasis on thermal comfort and IAQ, as well as proposing methods, techniques and interventions for the improvement of IEQ. Investigations correlating the identified indoor conditions and interventions to building types, characteristics and applications should also be included, together with works investigating the relation of the achieved levels of indoor environment satisfaction with energy savings. This relation, having lately concerned the relevant Building Regulations, e.g. EPBD, should be clearly quantified, also involving aspects related to the controlling of the operation of the relevant energy systems or building envelope devices with regard to monitored proper input data.

The Special Issue welcomes submissions on the following topics:

  • Assessment of Indoor Air Quality and/or thermal comfort in specific buildings/applications.
  • Indoor environmental quality (IEQ) aspects.
  • Measurement methods and techniques for the assessment of IEQ.
  • Correlation of IEQ, mainly IAQ and thermal comfort, with health impacts.
  • IEQ improvement methods, techniques and means.
  • The effect of building materials, design and use on IEQ
  • Linking IEQ aspects with energy efficiency.
  • Control methods and techniques for optimizing IEQ.
  • The relation of IEQ and energy efficiency as highlighted in Building Regulations.

The complicated nature of indoor environmental quality (IEQ) (thermal, visual, acoustic comfort, etc.) dictates a multi-fold approach for desirable IEQ levels to be achieved. The improvement of building shells’ thermal performance, imposed by the constantly revised buildings’ energy performance regulations, does not necessarily guarantee the upgrade of all IEQ-related aspects, such as the construction’s acoustic quality, as most of the commonly used insulation materials are characterized by their low acoustic performance properties. From this perspective the SUstainable PReconstructed Innovative Module (SU.PR.I.M.) research project investigates a new, innovative preconstructed building module with advanced characteristics, which can, among other features, provide a high quality of acoustic performance in the indoor space. The module consists of two reinforced concrete vertical panels, between which the load bearing steel profiles are positioned. In the cavity and at the exterior surface of the panel there is a layer of thermal insulation. For the scope of the analysis, different external finishing surfaces are considered, including cladding with slate and brick, and different cavity insulation materials are examined. The addition of Phase Change Materials (PCM) in different mix proportions in the interior concrete panel is also examined. For the calculation of the sound insulation performance of the building module the INSUL 9.0 software is used. The results were validated through an experimental measurement in the laboratory in order to test the consistency of the values obtained. The results indicate that the examined preconstructed module can cover the sound insulation national regulation’s performance limits, but the implementation of such panels in building constructions should be carefully considered in case of lower frequency noise environments.

The building sector consumes 36% of the world’s energy and produces around 40% of energy-related carbon emissions. While the building industry moves towards a zero net greenhouse-gas emission policy, ventilation is, and will be, a necessity for the preservation of air quality—especially in climates defined by unsavoury conditions. Therefore, a “mixing mode” cooling system was employed to lower the required energy consumption at an earthen building situated in the premises of Istanbul Technical University. A room of the high-mass earthen building was monitored under different ventilation and shading conditions. Night ventilation was conducted using two modes, 3.2 and 2.3 air changes per hour, and the air conditioning unit, operating from 08:00 to 17:00, had a set temperature of 23 C. Night ventilation was somewhat impactful, reducing the average expected cooling energy demand up to 27%. Furthermore, the earthen building proved to be extremely effective on moderating extremes of temperature under non-ventilated conditions. During a rather hot day, with an outdoor maximum temperature of 35 C, the indoor maximum temperature of the high-mass building was only 25 C, namely within thermal comfort levels. The diurnal temperature proved to be key in the effective application of night ventilation. Full article
