Passive Strategy

Interior space comfort encompasses design performance criteria beyond the thermal qualities of the space. The acoustic performance has shown to be an essential factor for the productivity levels of the users of the space, and is essential for overall indoor environment quality to be maintained. This research focuses on the potential of integrating living walls within indoor spaces, such as atriums and halls, to provide a passive strategy for noise insulation. The procedure is conducted through a series of acoustic measurements and calculations to determine the sound absorption coefficient of living walls in-situ. A case study space is used to evaluate the integration of living walls to provide acoustic comfort.

Acoustic Comfort

This article describes the design and development of a low-cost, portable monitoring system for indoor environment quality (IEQ). IEQ is a holistic concept that encompasses elements of indoor air quality (IAQ), indoor lighting quality (ILQ), acoustic comfort, and thermal comfort (temperature and relative humidity). The unit is intended for the monitoring of temperature, humidity, PM2.5, PM10, total VOCs (×3), CO2, CO, illuminance, and sound levels. Experiments were conducted in various environments, including a typical indoor working environment and outdoor pollution, to evaluate the unit’s potential to monitor IEQ parameters. The developed system was successfully able to monitor parameter variations, based on specific events. A custom IEQ index was devised to rate the parameter readings with a simple scoring system to calculate an overall IEQ percentage. The advantages of the proposed system, with respect to commercial units, is associated with better customisation and flexibility to implement a variety of low-cost sensors. Moreover, low-cost sensor modules reduce the overall cost to provide a comprehensive, portable, and real-time monitoring solution. This development facilities researchers and interested enthusiasts to become engaged and proactive in participating in the study, management, and improvement of IEQ.

The City

Houses are spaces where we spend most of our lives, meeting our accommodation needs and reflecting us and our personality. The tunnel formwork systems are effective in house production. They appeal to the people in different social status varying from high-incomers to low-incomers from the city center to the peripheries of city. Based on such determination, the satisfaction of house user set forth the main line of work. For this purpose, six parameters have been ascertained to determine the user’s comfort, by interrogating the comfort of interior space in the houses: The thermal comfort, visual comfort, acoustic comfort, humidity and moisture control and design quality. With the purpose of interrogating the user’s satisfaction, four mass housing areas constructed with tunnel formwork system in İzmir have been investigated. These are: Gaziemir Emlak Bankası Houses, TOKI Uzundere Houses, Mavişehir Stage I and Mavişehir Soyak Houses. After providing general information about all these mass houses, the surveys applied to the users have been evaluated.

Open Plan

Acoustic comfort in open-plan offices is a relatively recent research topic and some practices have not yet been consolidated. The goal in these spaces is to achieve good speech privacy at every workstation, reaching a high value of spatial decay of the sound pressure level. In case of refurbishment, a proper measurement of intelligibility criteria is needed, for example, in order to properly calibrate a numerical model or to plan acoustic treatments. This work compares different measurement techniques to evaluate the spatial distribution of intelligibility criteria. In situ measurements were done in an open-plan office used as a case study. Both omnidirectional and directional sound sources with different sound power levels were used, according, respectively, to ISO 3382-3:2012 and ITU-T P.51:1996. Furthermore, compensation algorithms were used in impulse response measurements in presence of Heating, Ventilation and Air Conditioning noise. The study shows, in a preliminary way, how different techniques and equipment can influence intelligibility criteria used in the open-plan office characterization. Results show that the indirect method of measuring Speech Transmission Index could not be used when the background level is high as the case study while the direct method returns good results.

Abstract The article contains the analysis of experimental ventilation measurement in selected classrooms of the Elementary School Štrba. Mathematical model of selected classroom was prepared according to in-situ measurements and air exchange was calculated. Interior air temperature and quality influences the students ´ comfort. Evaluated data were compared to requirements of standard (STN EN 15251,2008) applicable to classroom indoor environment during lectures, highlighting the difference between required ambiance quality and actually measured values. CO2 concentration refers to one of the parameters indicating indoor environment quality.

Window Design

Windows are elements of great incidence on building consumption and therefore with great saving potential. When designing high-energy efficiency windows, it is possible to negatively influence the indoor environment quality. To ensure indoor environmental quality, hygrothermal comfort, acoustic comfort, luminous comfort, physical-chemical and microbiological contaminants in the air, and the electromagnetic environment must be considered. Of all these aspects, windows intervene in four of them: hygrothermal comfort, luminous comfort, acoustic comfort and air quality. In order to carry out a comprehensive design, designers should study in detail the variables mentioned for each particular case and, consequently, act. This, due to the means and the deadlines with which the prescriber usually counts on, is currently not viable. This research responds to current deficiencies by proposing the development of a product indicator through an integrative procedure for window design that simultaneously contemplates indoor environmental quality, energy efficiency and cost, integrating environmental and socio-economic aspects. The indicator proposed here provides information substantially superior to that currently available to technicians, to be used as a decision making tool.
