Construction industry forecasting system dynamic model

In a paper construction branch forecasting model which allows to estimate the industry development problems is shown. Difference from anthers models, in given paper the main attention is turned to the building of the living area. Model stands from sub model (blocks): amount of apartments, real estate prices, necessity of apartments and living area forecasting models. Their essence and necessity are shown in separate sections. In the paper final, produced model is applied practical, are given model forecasts. The apartments amount forecasting model show supposition, in which, if there is deficit of dwellings in the economic system, then, first of all, are finance and construct apartments with little areas, i.e., multistory buildings with one-room apartments. Apartment’s amount increase depends from the building financing, as also from middle apartment area and building costs of square meter. The real estate prices forecasting model show supposition, that the once certain price is actual while it is not changed with prices influential parameters. The prices influential parameters are: extend (or diminish) of the live fund, the total market influence on separate market segments (and vice versa). The apartment’s necessities forecasting model show supposition, that in beginning a certain volume of necessities remains not changed, while on their has not changed with influential factors. Between the influential factors there are: apartments amount increase – it diminish apartments amount necessities; apartments wear (amount diminish) - it increase apartments amount necessities; improve of live circumstances - it diminish apartments amount necessities. The live area forecasting model is an additional model, which provides functioning of another’s models. Shown supposition was related with a population tries to purchase apartments with such properties which is similar to present at the market apartments. Till with it the middle area in each analyse group is not changes. In not changes middle area circumstances, knowing apartments amount, it is possible to calculate the total live area. Accumulating statistical data it is to adjoin with a problem, that not all data was certain, for a few data only possible borders of oscillations are certain. Till with that, in the paper are examined a few possible situation development variants. Buildings and real estate market development simulated on separate its segments and in an aggregate. Analysing the forecast data for aggregate apartments building in Latvia, in basic scenario it is certain, that the counterbalanced apartments building volume is about 1800 apartments in the year, but noticing oscillations of overproduces and necessities, this size can brief hesitate from 1434 to 2019. A sensitiveness analysis confirms basic scenario, complements it and extends with credible horizon borders.construction demand, housing fund, system dynamic, market modeling, simulation, economic forecasting

KECENDERUNGAN PERUBAHAN BENTUK DAN POLA TATA RUANG RUMAH SUSUN PEKUNDEN SEMARANG

The Ministry of Public Statement tried to overcome the problems of urban settlement through the approach of “1000 Towers” program, which is the provision of 1000 units of apartments for urban people. However, it is a pity that, that approach was only from its physical aspects; meaning that when the government provided those apartments, it paid its attention only on the tehnical and economic aspects. Whereas, on the other side, people who will live in those apartments are people that have the habit of neighbourhood life with specific and unique socio-cultural behaviors that had been constructed for so long. When they live and use the apartments, they need a long adaptation process, even in a certain extent; it may causae pronologed stress for the inhabitants. Government policy to provide apartments for the low economic people deserves to be appreciated, however, from the aspect of design approach, it still requires further attention. The mass apartment construction on one side causes problems because not all prospects of inhabitant have the same perception and aspiration; as a result, the well-prepared apartment design is eventually unable to accommodate the needs of its inhabitants. This research tries to reveal the behaviors of the inhabitants, why they have the tendency of changing form and pattern of their spatial arrangement especially at the Pekunden Apartments of Semarang. The research results do not reveal only the background of inhabitants motivation, however, they also reveal what the changes of form and pattern of spatial arrangement look like and the impacts emerging after the changes. The result of the act of revealing of inhabitants motivational background and occurring changes of form and pattern of spatial arrangement will be used as the evaluation materials for improvements of the design of apartment, not only in Pekunden, however they are also for other apartments that have not been built yet. Keywords : slum settlement, apartment, form and pattern spatial arrangement. 1 Staf pengajar, Jurusan Arsitektur, Fakultas Teknik, Universitas Diponegor

Metric characterizations of spherical, and Euclidean buildings

A building is a simplicial complex with a covering by Coxeter complexes (called apartments) satisfying certain combinatorial conditions. A building whose apartments are spherical (respectively Euclidean) Coxeter complexes has a natural piecewise spherical (respectively Euclidean) metric with nice geometric properties. We show that spherical and Euclidean buildings are completely characterized by some simple, geometric properties.Comment: Published by Geometry and Topology at http://www.maths.warwick.ac.uk/gt/GTVol5/paper17.abs.htm

Apartemen Mahasiswa UNSRI Di Indralaya

UNSRI student apartments in Indralaya is a place of residence for students and prospective students who come from out of town or in the city to live and also facilities that support the education of universities UNSRI Indralaya. UNSRI student apartments in Indralaya consists of several facilities, namely living room as a residence and other supporting facilities as a requirement in the activities such as: food court, clinic, library, sports facilities, and musholla. All these facilities are accommodated in two building masses. The development of UNSRI student apartments in Indralaya is also a step from the questionnaire that has been distributed to the students of UNSRI Indralaya. Based on the results of the questionnaires from 43 respondents obtained 31 new project respondents to accommodate the students who need a place to live near the campus area. The theme applied to the design of student apartments UNSRI in Indralaya is "Level". This theme is taken because of the philosophy that can be used to increase the level like school education into college. This theme is embodied in the form of a contemporary building with a green architecture approach

A hybrid property pricing model : the case of apartment residents in Jakarta Indonesia

Purpose: This research initiates a property pricing model that involves various perspectives and consumer considerations in selecting properties, including aspects of sales comparison, investment, hedonic life style, brand equity, and digital life style. Design/Methodology/Approach: The study investigates 222 residents of middle class apartments in Jabotadebek (Great Jakarta). The study employs Structural Equation Modelling (SEM) to test the research hypotheses. Findings: The research found that the price of apartments in the region is strongly influenced by a combination of multi aspects of sales comparison, investment, hedonic life style, brand equity, and digital life style. Practical Implications: The research has implications for investment shows the weakest contribution to the apartment price. Originality/Value: This study found that the price of apartments in the region is strongly influenced by a combination of multi aspects of sales comparison, investment, hedonic life style, brand equity, and digital life style.peer-reviewe

Non-integrality of some Steinberg modules

We prove that the Steinberg module of the special linear group of a quadratic imaginary number ring which is not Euclidean is not generated by integral apartments. Assuming the generalized Riemann hypothesis, this shows that the Steinberg module of a number ring is generated by integral apartments if and only if the ring is Euclidean. We also construct new cohomology classes in the top dimensional cohomology group of the special linear group of some quadratic imaginary number rings.Comment: 17 pages.

The uneven price impact of energy efficiency ratings on housing segments and implications for public policy and private markets

In the literature, there is extensive, although in some cases inconclusive, evidence on the impact of Energy Performance Certificates (EPC) on housing prices. Nonetheless, the question of whether such an impact is homogenous across residential segments remains highly unexplored. This paper addresses this latter issue utilizing multifamily listing data in metropolitan Barcelona. In doing so, first the entire sample is analyzed using a hedonic model. Second, the sample is split on the basis of a multivariate segmentation. Finally, separated hedonic models are specified again. The results suggest that in general, there is a modest impact of EPC ratings on listing prices, nonetheless it is not homogeneous across housing segments: (1) for the most modern apartments, with state-of-the-art features and active environmental comfort, energy ratings seem to play a null role in the formation of prices; (2) conversely, for the cheapest apartments, apartments boasting the most basic features, and apartments located in low-income areas, the “brown discount” is enormously significant, potentially depreciating the equity of those who have the least resources to carry out an energy retrofit. These results have implications for the assessment of the EPBD and its Spanish transposition, since a very well-intentioned environmental policy could have potentially harmful social repercussions in the absence of corrective measures.Peer ReviewedPostprint (published version
