Comfort Criteria

As the need of the train speed increased, the existing bridges need to be evaluated, especially in dynamic responses, which are deformation and acceleration. In this study, Cisomang Bridge is modeled and analyzed due to the high-speed train SJ X2 in varying speeds, 50 km/h, 100 km/h, 150 km/h, and 200 km/h. The used of tuned mass damper also will be varied on its setting and placing. The tuned mass dampers setting be varied based on the first or second natural frequency and the placing of tuned mass damper be varied based on maximum deformation of the first or second mode. Moreover, the tuned mass damper ratio will be varied 1% and 1.6%. For all speed variations, dynamic responses of structure without TMD still fulfil the Indonesian Government Criterion based on PM 60 - 2012 but do not meet requirement of comfort criteria based on DIN-Fachbericht 101. Furthermore, only for the speed train 50km/h dynamic responses of structure fulfil safety criteria based on Eurocode EN 1990:2002, whereas the other speed variations do not meet that requirement. In the use of TMD 1% mass ratio, the structure fulfils the safety criteria for all speed variations. In the use of TMD 1.6% mass ratio, all the structure fulfils the safety and comfort criteria except 100 km/h speed which only fulfils the safety criteria.

Impacts Of Climate Change

In recent years, climate change has been getting more serious. How to mitigate and adapt to climate change has caught the concerns of governments and academia. Firstly, this article briefly addresses the causes of climate change and its impacts, and then analyzes the link between climate change and urban settlements and the impacts of climate change to urban settlements in winter city. Finally, according to the Characteristics of winter city, the paper presents some optimization strategies of urban residential quarter in winter city addressing climate change including reducing carbon emissions, ensuring settlements security and guiding residents to public participation. Reducing urban settlements carbon emissions includes improving internal functions, combing the internal transportation system, optimizing the green mode and applying special techniques. Protecting the safety of urban settlements includes improving emergency response system, strengthening the vertical and horizontal connection and optimizing the layout of public space. Guiding residents to public participation includes establishing the information banks of urban settlements addressing to climate change and improving the quality of the residents.

With the advent of the knowledge economy and the rapid development of information technology era, people's demand for the living environment has been far more than mere material comfort. In this paper, good landscape design for residential quarter not only provides appropriate living conditions for dweller, satisfies people's yearning for home, improves the quality of urban environment, but also is the main prerequisites which measure the green quality and management of the community. Landscape planning and design of residential environment exists failed plant landscape design, weak user-friendly design, ignoring landscape such as issues. We have identified the principles of landscape planning and design community, and allocation of green plants. It is the important weights that real estate developers sell their items, which is an important success factor that the real estate developers operate company, and people will pay more and more attention to the landscape design.

AbstractAll over the world, a large part of existing buildings is not adequate to satisfy the safety requirement and the thermal comfort criteria. For this reason, the interest in structural and energy retrofitting systems has steadily grown in the last decades. In this scenario, an innovative thermal resistant geopolymer mortar has been developed and used for Inorganic Matrix Composite (IMC) systems aimed to a combined seismic and energy new retrofitting technique. The geopolymer-based IMC is able to ensure competitive mechanical properties with respect to the traditional lime-based IMCs and, at the same time, a significant reduction in thermal conductivity. In this paper, an experimental program is reported considering small-scaled masonry panels with double-side IMC-retrofitting and determining both the in-plane shear strength and the thermal resistance. The experimental shear tests are aimed to compare the mechanical performance of the geopolymer innovative systems with those of the traditional lime-based ones. Moreover, the thermal resistance gain of the innovative solutions was measured and compared with traditional systems. The results evidenced the effectiveness of the proposed technique that significantly improved the performances of masonry walls from both the thermal and the mechanical point of view.

Comfort Criteria

Recent research suggests that a time-varying indoor thermal environment can lead to energy savings and contribute to boost buildings' energy flexibility. However, thermal comfort standardization has so far considered thermal comfort criteria as constant throughout the day. In general, very little attention has been given to the ‘ time of day' variable in the context of thermal comfort research. In this paper, we show some evidence of a time-varying thermal perception by using: (1) data from about 10,000 connected Canadian thermostats made available as part of the ‘ Donate Your Data' dataset and (2) about 22,000 samples of complete (objective + ‘ right-here-right-now' subjective) thermal comfort field data from the ASHRAE I and SCATs datasets. We observe that occupants prefer colder thermal conditions at 14:00 and progressively warmer ones in the rest of the day, indistinctively in the morning and evening. Neutral temperature differences between 08:00 and 14:00 and 14:00 and 20:00 are estimated to be of the order of 2°C. We hypothesize that the human circadian rhythm is the cause of this difference. Nevertheless, the results of this study are only based on observational data. Thermal comfort experiments in controlled environmental chambers are required to confirm these findings and to better elucidate the effects of light and circadian timing and their interaction on thermal perception.

Comfort Criteria

University studies for the architecture degree in Spain give very little weight to considerations related to the design of a healthy interior environment. The low number of subjects related to interior comfort criteria may cause the student to underestimate the importance of environmental design of closed spaces in favor of aesthetic or merely functional aspects. However, there is a direct relationship between formal design decisions and environmental conditions in buildings, and future architects must understand those connections in order to make designs that combine efficiency and high aesthetic value. In this chapter, several pedagogical strategies are presented to get architecture students to learn and internalize the link between design and interior conditions, aiming at the acquisition of an adequate environmental awareness.
