UWG -TRNSYS Simulation Coupling for Urban Building Energy Modelling

This paper presents a new methodology to carry out building performance simulation at the district scale integrating the building thermal model TRNSYS with the climate model ‘Urban Weather Generator’ (UWG). The integrated methodology is designed to include the microclimatic modifications induced by urban environments on buildings’ cooling load calculation. The impact of shadows, air temperature increase and urban radiant environment on building cooling performance has been highlighted for hot arid climates (Antofagasta, Chile). Results indicate that the impact of urban context on energy performance of buildings at the neighbourhood scale varies significantly with building typology and urban tissue densit

Kajian Arsitektur Vernakular pada Bangunan di Kampung Mahmud

Kampung Mahmud is one of the villages in Indonesia. Normally an indigenous village generally have distinctive features and special rules one of them is building. The building was established following the climate, culture, environment and materials, religion/beliefs, tradition law, science and technology at the time. Based on these, so Kampung Mahmud can be regarded as a vernacular village. Simplicity that highlighted of building be a characterize of building typology which existing in Kampung Mahmud. Nowadays building typologi in Kampung Mahmud has changes a lot started with the times. By qualitative research methods, survey, observations and interviews with relevant parties, obtained aspects that influence the development of the alteration building typology in Kampung Mahmud

National scientific report on the TABULA activities in Italy

The Italian contribution to the TABULA research project is decribed. Ii was addressed to: - the development of the harmonised structure for the Italian typology and the supply of input data on buildings, constructions and systems (heating and DHW), which constitute the main data for the webtool; - the application of the typology concept for the assessment of the energy performance of residential buildings and for the evaluation of the impact of energy conservation measures, through the calculation of the energy performance of the building-types; - the use of the typology concept to create a model for the estimation of the national energy balance of the residential building stock by the support of national statistical dat

Calculation of the Risk of Lawsuits over Construction Flaws in Flat Roofs

In order to achieve sustainability objectives in the use of a building, its elements’ operating problems should be minimized. From this premise, a total of 497 cases related to construction flaws in flat roofs were analyzed in this research. A matrix was developed indicating the risk of lawsuits by owners according to the degree of nuisance resulting from the construction flaws studied, their technical importance, and the type of pathological origin. Based on these factors, it is possible to predict a greater or lesser probability of an owner filing a lawsuit—risk factor (F). A wide range was found for this probability, with the largest value being 865 times greater than the smallest value. The value of F was divided into 5 categories to classify the diverse results obtained and determine the number of cases and interrelations ascribed to each category. Additionally, the level of presence of said cases was calculated through the analysis of 3 di erent demographic aspects, it being noted that a greater purchasing power and a higher concentration of urban population lead to more stringent requirements and, subsequently, to a greater number of lawsuits. With all these results, building quality can be improved while resulting in greater constructive-financial sustainability and in a reduction of the economic resources required of society (fewer lawsuits and associated human resources)

Intervention in July 9th: A New Plan for Misurata City, Libya

Libya’s urban form has changed radically since the second half of the 19th century. Prolonged exposure to non-traditional and non-regional cultural, sociopolitical, economic, and design influences has caused certain developed areas to be plagued with many of the same problems the western world is facing in cities built within a similar framework. These blights include: high energy consumption, contaminated water, air quality, and traffic. This thesis explores the affect of the cultural crisis manifesting within the urban form. In order to design a contextually relevant building typology it is imperative to assess the architectural language of the culture. The portion of this project will include a historical evaluation of building typology in North African cities throughout time and in conjunction with population levels. Based on established patterns, and with the goal of driving future development in the right direction, a regionally responsive urban typology is to be developed. The chosen site for the building typology is one based purely on necessity of intervention. Due to recent revolutionary undertakings, the July 9th neighborhood in Misurata city, Libya, is used as an example to show how a new vision of a hybridized architectural intervention can prove to redefine how a city and its people relate to one another. This project looks to confront the problems of a region left destitute in the wake of war and destruction

Effect of Population Density and Urban Intensity on Building Typology in South Krembangan Area

Surabaya is the second largest city in Indonesia and is part of East Java. Surabaya has a strategic location and was utilized by the Dutch Colonial Government as one of the main ports. The Kalimas River served as the trading artery of Surabaya. Surabaya was broadly divided into three dominant areas: the European district, the Chinatown district, and the Arab district, all of which are delineated by the Kalimas River. Krembangan Selatan Village is of particular interest for research due to the presence of many colonial-style buildings and the shift from a historical trading area to a residential area.  To understand the influence of population density and urban intensity on building typology, a qualitative descriptive analysis was conducted by observing building typology and the year of construction which helped in determining how population density and intensity affect building typology in the Krembangan Selatan area. Urban Intensity was assessed by calculating the building volume divided by 300. The highest intensity group consists of residential areas with buildings in a typical style of the 1960s. Density calculations were made by comparing the area to Semarang, as both areas were influenced by the Dutch colonial Government.  This occurred because Semarang's Old Town area still maintains its urban tissue as a historical area dominated by public buildings, in contrast to Krembangan Selatan, which is dominated by service providers, educational facilities, and residential buildings

High performance low-energy buildings

The era of legislation and creditable methods towards producing sustainable buildings is upon us. Yet, a major barrier to achieving environmental responsive design is in the lack of available information at the programming or pre-design phases of a project. The review and evaluation of climate as well as energy-efficient strategies could be difficult to consider at these preliminary stages. Until recently, introducing energy simulation tools at the design stage has been difficult and perhaps next to impossible at a pre-design or programming stage. However, analysis of this sort is essential to &lsquo;green building rating&rsquo; or performance assessment schemes such as LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environment Assessment Method). This paper discusses the implementation of a particular tool, ENERGY-10, where &lsquo;basecase&rsquo; building defaults are compared to a low-energy case which has applied multiple energy-efficient strategies automatically. An annual hour-by-hour simulation provides a daylighting calculation with a subsequent thermal evaluation. Calculation results provide energy consumption, peak load equipment sizing, a RANK feature of the energy-efficient strategies, reporting of CO2, SO2 and NOx reduction, optimum glazing type as well as excellent graphic output. Consideration is given as to the approach of how such information can be introduced into the building project brief enforcing a low-energyperformance target.<br /

Extending displacement-based earthquake loss assessment (DBELA) for the computation of fragility curves

This paper presents a new procedure to derive fragility functions for populations of buildings that relies on the displacement-based earthquake loss assessment (DBELA) methodology. In the method proposed herein, thousands of synthetic buildings have been produced considering the probabilistic distribution describing the variability in geometrical and material properties. Then, their nonlinear capacity has been estimated using the DBELA method and their response against a large set of ground motion records has been estimated. Global limit states are used to estimate the distribution of buildings in each damage state for different levels of ground motion, and a regression algorithm is applied to derive fragility functions for each limit state. The proposed methodology is demonstrated for the case of ductile and non-ductile Turkish reinforced concrete frames with masonry infills
