Authors: Davis Esther L. , Kelly Peter J. , Deane Frank P. , Baker Amanda L. , Buckingham Mark , Degan Tayla , Adams Sarah 
Published: October 2019

Background: Patient-centered care is strongly advocated as a key for improving the quality of healthcare. Research examining the impact of patient-centered care in healthcare has concluded that there are demonstrable albeit inconsistent relationships between patient experience, quality of care, and healthcare outcomes. Knowledge of the impact of patient-centered care in the treatment of substance use disorder is limited. The aim of this review was to assess relationships between indicators of patient-centered care (satisfaction and patient-reported experience measures) and patient outcomes (substance use, psychological wellbeing, and service use) among people attending treatment for substance use disorder. Methods: A systematic electronic literature search of a range of databases was conducted with variations of the search terms ‘patient-centered care’, ‘substance use disorders’, and residential or community specialist ‘treatment’. The populations, interventions and outcomes were summarized and described according to the PRISMA statement. Results: A total of 25 articles were identified, of which only five included a patient-centered indicator other than satisfaction. Indicators of patient-centered care showed a generally positive association with improved outcomes, particularly between satisfaction with treatment and substance use. Nonetheless, mixed and contradictory results were not uncommon, more so for psychological wellbeing outcomes. Conclusions: There were demonstrable relationships between patient-centered indicators and outcomes for people receiving treatment for substance use disorder. However, conclusions are limited due to underrepresentation of patient-reported experience measures. Further research in the area is needed involving comparisons of patient centered indicators with outcomes and use of patient-reported experience measures together with satisfaction.

Operating room ventilation with laminar air flow ceiling and a local laminar air flow system near the operating table for the patient
Authors: Tacutu Laurentiu , Nastase Ilinca , Bode Florin 
Published: October 2019

Abstract
The aim of this study is to determine how the air flow from a unidirectional air flow (UAF) system and a local ventilation system will interact with each other. The study analyzes the air circulation near the operating table at different air flow velocities from both systems. The air flow velocities correspond to the usual range of velocities that are recommended by norms and guidelines. The research was approached by numerical and experimental studies. The thermal plume of the patient was measured by Particle Image Velocimetry (PIV) and thermography (IR) and compared with the results from the numerical case. A mesh independency study was made for the numerical case. The study showed that velocities ≥0.2 m/s from the UAF, depending on the height of the room, can overcome the thermal plume generated by a human subject with a moderate activity (100÷120W). The velocities from the local ventilation system need to be higher with at least one step, in accordance with the distance from the ventilation system to the operating wound, in order to avoid disturbances generated from the UAF system.

Published: October 2019

Abstract
This paper presents results from a project on the assessment of the indoor air quality (IAQ) benefits that might accrue from the use of a balanced ventilation system. The study compared the whole-building pressure, IAQ and ventilation performance of energy recovery ventilation (exhausting from kitchen and bathrooms) with that of exhaust-only ventilation (continuous exhaust from master bathroom). The side-by-side comparisons included various indoor mixing scenarios (no mixing, partial mixing and continuous mixing) using the NRC’s twin research houses. The side-by-side testing showed that balanced ventilation (energy recovery ventilation) was superior as a whole-house ventilation strategy, compared to unbalanced ventilation (single-point exhaust ventilation). It was superior because of the positive indoor pressure (1 to 3 Pa), higher air change rate (6% to 34%), uniform inter-zonal air flows, lower concentration of formaldehyde (by 37% to 70% in winter and 6% to 34% in summer), lower concentration of VOCs in winter (alpha-Pinene by 26% to 89% / Toluene-d8 (dTol) by 8% to 76%) and in summer (α-Pinene by 87% to 339% / Toluene-d8 by 45% to 88% / Heptane by 40% to 91% / Benzaldehyde by 35% to 406%), and as expected lower whole-house heating/cooling and ventilation energy consumption by up to 8.5%.

Abstract
Taiwan has entered aged society, the elderly are more and more dependent on long-term care institutions. Furthermore, the subjects for long-term care institutions in Taiwan are the elderly population and disabilities who are susceptible to the effects of indoor air quality. If people stay in the space with such poor indoor air quality, they may get sick building syndrome (SBS), allergy, and other respiratory diseases. The poor ventilation could make the disease worse and increase the probability of disease outbreaks.
The purpose of this study is to investigate to the benefit to control the indoor air quality in a room and to give a solution to indoor air quality (IAQ). On the other hand, we used software called computational fluid dynamics (CFD) to simulate a suitable ventilation strategy. We aim at investigating the performance of decrease carbon dioxide (CO2) concentration and other indoor air quality indicators and making an approach to the correlation between indoor air quality and flow movement.

Published: October 2019

Abstract
The villas of Costozza (Vicenza, Italy), built in 16th century, give an example of bioclimatic architecture actual even today. These villas are connected to a large underground cavities network present inside the nearby hills, that can dissipate heat to the ground and provide cool air in summer. Here is analysed Villa Aeolia, still in operation, modelling its natural cooling system in a day of July by using steady-state 3D Fluid Dynamics computations. We focus on three scenarios depending on the outdoor temperature, that follows the daily temperature variations. The simulations let us to know the indoor velocity field and the temperature distribution in the main hall, the Sala Apollinea. Then, we evaluate the global thermal comfort and local discomfort by determining the sensation index Predicted Mean Vote, Predicted Percentage of Dissatisfied and Draught Rating at 1.1 m above the hall floor. This method can easily be implemented in others cases and allows to have a spatial evaluation of comfort and therefore to identify in the different scenarios which are the parameters on which to act in the event of local discomfort.

Published: October 2019

Abstract
Stratum ventilation (SV) can energy-efficiently provide satisfactory thermal comfort under cooling mode. However, thermal comfort and energy efficiency of SV under heating mode can be different from those under cooling mode due to the distinct airflow patterns. In this study, thermal comfort and energy utilization efficiency of SV were investigated for six cases under heating mode. Air velocity and temperature were measured in the occupied zone of a multi-occupant room with dimensions of 8.4 m (L) ×5.4 m (W) ×2.6 m (H). Based on the measured air velocity and temperature, the thermal comfort indicators including vertical air temperature between head and ankle levels (ΔT), draught rate (DR), predicted mean vote (PMV) and energy utilization efficiency were calculated. The results showed that the energy utilization efficiency of SV was higher than one under heating mode, indicating energy saving. The draught rate under SV satisfied the requirement of Category B of thermal environments stipulated in ISO 7730. The PMV of SV can meet the acceptable range for general thermal comfort under the cases with suitably high supply air temperature according to ASHRAE 55-2017. The vertical air temperature difference between head and ankle levels can achieve acceptable results for SV under heating mode.

Published: October 2019

Abstract
Filtration is a simple and effective way to capture particles of different sizes used in different workplaces. However, the state of current knowledge has shown that the performance of entire filter depending on the particle size are still very limited. The main objective has therefore been to develop a procedure to evaluate the filter performance used in ventilation systems for particles smaller than 300 nm including nanoparticles. The measurement procedure has been validated by comparing the penetration measurements on two different setups for nanoparticles.
Full-scale experimental study of moisture condensation on the glazing surface: condensation rate characterization
Authors: Nguyen C K , Teodosiu C , Kuznik F , David D , Rusaouën G 
Published: October 2019

Abstract
Excessive indoor moisture promotes the growth of mold and condensation on building envelope, which lead to severe IAQ problems. Given the transient, unsteady heat and mass transfer problem, studies dealing with the condensation phenomenon are generally lacking in the literature, especially studies on the condensation rate prediction. Consequently, this paper presents a method to quantify experimentally the condensation rate of droplets formed on a cold glazing surface in a full-scale entirely controlled test room (6.2 x 3.1 x 2.5 m). The condensation qualitative characterization, i.e. the moment of its appearance and its growth mechanism, is achievable using a macro-photography technique. From the time-series of droplet images captured, an image post-processing method is used to detect the droplet contours and to estimate the condensation mass flow rate. Comparisons between experimental and theoretical results show some agreement, which could validate the feasibility of imaging techniques in full-scale condensation studies. Those first results are encouraging and valuable since there were no similar studies in the literature at such the scale. Further investigations are needed in order to clarify all these aspects related to the accuracy of the condensation rate quantification methodology developed in this work.

Authors: Dong Xin , Yang Zhenjing , Xu Yanan 
Published: October 2019

Abstract
In order to research the climate responsive of roof buffer space in Tujia traditional folk dwellings, two typical dwellings were taken as the research objects to measure relevant environmental parameters. Subsequently, the measurements were compared to analyze the coupling relationship between roof buffer space and indoor thermal environment. Analysis shows that the roof buffer space has the remarkable ability to block solar radiation, with the cooperation of valley-mountain breeze, which makes up for the shortcomings of poor thermal inertia and small heat insulation of wooden-plank wall dwellings: The indoor temperature peak reduces 2 °C; the range of difference between indoor average radiant temperature and the air temperature is 0.46 °C all day. The findings can guide the construction of modern wood-framed dwellings.
Climatic potential maps of ventilative cooling techniques in Italian climates including resilience to climate changes
Authors: Chiesa Giacomo 
Published: October 2019

Abstract
Building energy consumptions for space cooling is a globally rising voice. Considering the need to reduce the total energy consumptions and related GHG, alternative solutions based on natural heat sinks are essential. Unfortunately, these technologies, such as passive cooling systems, are vey local specific and their geo-climatic applicability needs to be studied to correctly choose and integrate them since early design phases. The paper studies the distribution of climate-related demand for cooling in the Italian context, by mapping local CDH (Cooling Degree Hours) together with the local potential of ventilative cooling dissipative technologies (e.g. controlled natural ventilation), for present and future climate conditions. A geo-referenced matrix – considering all the 7978 Italian Municipalities – of typical meteorological years will be generated and further analysed on hourly base by developing Python scripts. Results of this analysis are visualized in devoted maps of applicability able to underline the local expected potential of wind-driven ventilative solutions. These maps can act as a reference toolkit for designers considering early-design evaluations. Finally, the expected resilience of local climate-potential of these technologies to climate changes is analysed.
Simulations of a novel demand-controlled room-based ventilation system for renovated apartments
Authors: Smith K M , Kolarik J 
Published: October 2019

Abstract
The study simulated and assessed a novel control algorithm for an innovative room-based ventilation system for renovated apartments. The novel system is a manifold of fans that connects to an air-handling unit to control the supply of airflow to each room in an apartment. The exhaust side has a 3-way damper to control the division of extract airflows. The simulation required demand-control of ventilation airflows in each room. This included CO2- and temperature-based control of supply to dry rooms and humidity- and temperature-based control of exhaust from wet rooms. The object-oriented software IDA-ICE includes a graphical interface for assembling the controls, which enabled custom simulations. The controls efficiently maintained sufficient air quality in each room and ensured balance of supply and exhaust. The room-based demand-controlled ventilation system achieved 74% savings in fan energy consumption relative to the reference constant air-volume system. The simulations indicated the need for less-resisting overflow vents in doorways to prevent infiltration heat loss when supplying bedrooms with greater airflow. Infiltration heat losses increased by 18% with closed doors despite the use of acoustic vents to assist overflow. Future measurements will aim to validate the demand-control algorithm and the performance of the novel system in real apartments.

Published: October 2019

Abstract
Nowadays a large portion of energy consumption is depends on Residential Building. For these reasons Mechanical ventilation, colling, heating such things also be improved. But Occupants take action to control their indoor environments to adjust their individual flavour. Window Opening & closing If this result is universally applicable most preferred behaviour to adjust their indoor environment. However these behaviour causes an increase in energy consumption in the building. Therefore, if the window opening and closing behavior can be predicted, it will lead to an increase the comfort in the building and a decrease in the energy consumption. Previous studies have confirmed that window opening and closing behavior is significantly affected by ambient temperature. This also indicates that the season also affects window opening. It can be seen that the machine learning algorithm has better prediction than the traditional regression model. The purpose of this study is to investigate the effects of building information (location, number of floors, area, completion year) and human characteristic for indoor environmental control(heating setting temperature), not on the environmental parameters(temperature, humidity, fine dust, etc.) applied to previous machine learning models in the prediction of window opening and closing behavior. If this result is normally applicable, it will make more realistic predictions possible than when predicting with existing environmental parameters alone. This will give a plausibility to the results of simulations on actual buildings.
Influences of stack effect and longitudinal ventilation on the movement of buoyancy-driven contaminants in sloping tunnels
Authors: Li P , Du T , Yang D 
Published: October 2019

Abstract
Sloping tunnels widely exist in mountainous regions and urban underground traffic systems. The dynamics of buoyancy-driven contaminants in a naturally ventilated slopping tunnel are generally different from that in a horizontal tunnel. Using the brine-water method and the light attenuation technique, we demonstrate that buoyancy-driven source location and source reduced gravity have significant influence on the steady-state density distribution in the sloping tunnel. The results suggest that the stack effect is an important factor influencing the movement of the buoyancy-driven flow in sloping tunnels. Subsequently, the dynamics of the buoyancy-driven flow in a longitudinally ventilated sloping tunnel are investigated. It is found that, under the combined effects of longitudinal ventilation and stack effect, multiple steady states exist for identical boundary conditions.

Authors: Kang Y , Yoo S-J , Ito K 
Published: October 2019

Abstract
To clarify the effect of their geometries on the formaldehyde emission rate from building materials, we established a numerical model and analysis method for quantitatively investigating the formation of transient formaldehyde concentration distribution in small, airtight, glass desiccators. The detailed geometries of the desiccators, formaldehyde emission materials and the adsorbent were reproduced as 3D digital models. Numerical analyses were carried out to investigate transient formaldehyde emissions, molecular diffusion, and sorption. We considered the effect of adsorbent evaporation based on a three-component gas mixture theory. The results of the numerical analyses confirmed the impact of the adsorption and diffusion resistance of the water surface on the measured formaldehyde emission rates.

Abstract
The rapid economic growth in the East Asian region has particularly raised the issue of air quality. Indoor Air Quality (IAQ) has also become an important research topic in the building environment. Indoor air pollutants are harmful to human health and are especially dangerous to vulnerable populations, such as elderly people and children. Wood interior remodelling can protect people’s health from indoor air pollutants and wood is and eco-friendly and sustainable building material with low thermal conductivity and humidity control. This study measured the IAQ of twelve welfare facilities in Korea which renovated the interior with wood materials to improve indoor air quality. In this study, twelve IAQ factors were measured as follows. Comfort factors (Temperature and Relative humidity), particulate matter, biological pollutants, air borne asbestos fibers, and chemical pollutants (carbon dioxide, formaldehyde, Volatile Organic Compounds, radon, ozone, nitrogen oxide and carbon monoxide). As a result, the measured value of the indoor air quality factors for 12 welfare facilities is as follows. The average particulate matter was less than 12μg/m3, the average of carbon dioxide was 754.2ppm, the formaldehyde was 46μg/m3, the volatile organic compounds was 335μg/m3, the total airborne bacteria was 37.8 CFU/m3and the radon was 59.5Bq/m3.

Published: October 2019

Abstract
Between 2017 and 2018, we conducted a longitudinal field experiment in a mixed-mode ventilation building located in Wollongong Australia, with a particular focus on occupant thermal comfort and adaptive behaviour. This study investigated how different building operation modes i.e. air-conditioning (AC) and natural ventilation (NV), can have an impact on occupant perception of thermal comfort. Time-and-place matching of objective (physically measured indoor climate parameters, outdoor meteorological data, and building operational information) and subjective data (i.e. occupant survey questionnaires) enabled empirical investigation of the relationships between those parameters. The result of the analysis revealed that subjective perception of indoor thermal environment can be affected by different modes of building operation. Occupants were found to be more tolerant of, or adaptive to, the indoor thermal conditions when the building was in the NV mode of operation compared to the AC operational mode. The applicability of the adaptive comfort standard to the mixed-mode ventilation context was also discussed.

Published: October 2019

Abstract
This paper researched the effects of different types of insulated roofs, PCM roofs, and composite roofs on the overheating risk (Ihot
) in the naturally ventilated classroom in Kaohsiung, Taiwan. The EnergyPlus was applied to simulate the hourly operative temperatures in the classroom. The optimal melting temperature (tmp
) and thickness of the PCM roof, as determined from design day, were 36°C and 26mm, respectively, which are consistent with the results from year-round simulations. The design PCM roof could decrease the Ihot
by up to 64%, leading to an effect equivalent to the decrease by 25mm insulation. However, with thickness of PCM>26mm or insulation>25mm, their effect on the Ihot
was not significant. The changes of Ihot
was insignificant while tmp
of PCM roof in the range of 34-40°C, and Ihot
increased rapidly when tmp
>40°C. The effect of tmp
of composite roof on the Ihot
was not significant.
