Short term Forecast Model of Apartment Jeonse Prices using Search Frequencies of News Article Keywords
Housing prices, including Jeonse prices, are impacted by human psychological attitudes. News articles are one of the factors that influence such human psychological attitudes. Previous studies have confirmed the potential for utilization of news articles in the analysis of the real estate market. However, no actual studies on real estate price forecasting through news articles have yet been carried out. Accordingly, the present study proposes a short term forecast model of apartment Jeonse prices through big data analysis of news articles. The forecast model was a regression model using Jeonse prices for apartments in the Pangyo area as the dependent variable and the Internet search frequency of news article keywords as the independent variable. The news article based forecast model was created from the independent variable made as a combination of 4 keywords with a time shift of 10 months. Comparison with time series models frequently used for real estate price forecasting showed that the model was superior in terms of forecast accuracy and forecast lead time. It is expected that use of the news article based forecast model according to the present study will allow for the establishment of more effective Jeonse price related policies.

Identification of Geographical Segmentation of the Rental Apartment Market in the Tokyo Metropolitan Area (Short Paper)
It is often said that the real estate market is divided geographically in such a manner that the value of attributes of real estate properties is different for each area. This study proposes a new approach to the investigation of the geographical segmentation of the real estate market. We develop a price model with many regional explanatory variables, and implement the generalized fused lasso a regression method for promoting sparsity to extract the areas where the valuation standard is the same. The proposed method is applied to rental data of apartments in the Tokyo metropolitan area, and we find that the geographical segmentation displays hierarchal patterns. Specifically, we observe that the market is divided by wards, railway lines and stations, and neighbourhoods.

Lightweight prefabricated floating buildings for shallow inland waters. Design and construction of the floating hotel apartment in Poland
Since the beginning of the 21st century floating buildings have been growing in popularity in Poland. According to market research and quantitative studies, the majority of operative Polish floating buildings serve for commercial purposes, such as short term rentals, vacation houses and floating marinas. Simultaneously, despite the increasing demand, the development of floating buildings in Poland is limited by the inconsistent legislation, government policy and, most importantly, natural conditions of Polish inland waters. The most attractive sites for floating architecture are the semi natural lakeshores and riverbanks. At the same time, low water levels and poor maintenance of many Polish basins require special architectural and engineering solutions. The article presents our experience with meeting the market's demand for small cost effective floating commercial buildings despite the local shortcomings of inland waters on the example of the floating apartment built in 2019 on the Ros Lake in Pisz, Poland. The presented building was intended as a water based extension of the existing hotel on land. It was designed as a "modern barn" with all glazed gable wall allowing for a spectacular view to the lake. With a 50 sqm footprint, the one story house with a mezzanine has a small draft of 33 cm and meets the stability criteria defined for inland waters. The presented case study shows that integrating the naval architecture theory, Building Information Modeling simulation along with cutting edge construction techniques such as Scottsdale Construction System (SCS) and polyurethane spray insulation, can bring significant progress into the development of the floating buildings market in Poland.

Cost optimization for overhauling the apartment blocks in Irkutsk, Russia
This paper analyzes the specifics and major shortcomings of the following documents: the Irkutsk Oblast Act No. 167 OZ of December 27, 2013 On the Arrangement of Common Property Overhauls in Irkutsk Oblast and the pertaining regulations, programs, and Short Term Plans Under the Irkutsk Oblast Regional Apartment Block Overhaul Program (hereinafter, common property stands for common facilities used by the residents of a single apartment block, e.g. rooftops, utilities, etc. It further analyzes the financial reports of the Irkutsk Oblast Apartment Block Overhaul Fund. The analysis demonstrates the costs of overhauling the apartment blocks in Irkutsk Oblast with breakdown by sources, the amount and source of funds coming from the region's municipalities as shown in the general funding structure of the Plan, and the specific jobs arranged under the City of Irkutsk Short Term Plan Under the Regional Apartment Block Overhaul Program in 2015 2016. To simplify the drafting of overhaul programs, the authors hereof present the estimates of roof overhaul costs per square meter with breakdown by overhaul related jobs; the estimates assume the use of novel materials: MasterSeal*501 and MasterEmaco*S 48. Such analysis reveals the roof job specific coefficients (multipliers) one needs to apply to find the actual overhaul costs for Series 135 panel buildings in Irkutsk. The authors propose an scenario based approach to design when drafting time adjusted short term overhaul plans. Time adjustment helps optimize such plans and minimize the change of a building being classified as a dilapidated apartment block.

Takt Planning in Apartment Building Renovation Projects
Takt production has been of great interest in construction during the last few years. In this research, a case study was carried out to demonstrate how the scheduling of an apartment building renovation project that utilizes takt production can be done. Furthermore, the study defines what clarifications should be made into the existing takt production models in the context of apartment building renovation projects, and it also explains why. Based on the study, adhering to a uniform production rate is challenging in apartment renovation projects. Therefore, a total of five clarifications to existing takt production methods are suggested. (1) Production with short takt requires a highly detailed definition of tasks in order to avoid ambiguousness. (2) Some tasks carried out in takt areas may have to be excluded from takt production. (3) The sensitivity of a created takt schedule should be evaluated, and buffers should be added accordingly. (4) Emphasis must be put on coordinating takted and non takted tasks. (5) Takt plan modification during production requires effective procedures, since there is little time to react.

Data driven based dynamic pricing method for sharing rooftop photovoltaic energy in a single apartment building
In this study, a novel data driven based dynamic pricing framework is proposed for sharing rooftop photovoltaic (PV) energy in a single apartment building. In this framework, the input includes the load data, electricity price data, and PV power data and the output includes the pricing strategy for local PV generations. Specifically, the building energy management system operator is responsible for setting internal uniform prices of their own rooftop PV productions to facilitate the local PV energy sharing with apartment building users, aiming to maximise the economic profits. To protect the privacy of apartment building users and meanwhile improve the computational efficiency, a neural network is designed for simulating their demand response (DR) behaviours. Besides, the uncertain rooftop PV generations can be duly addressed by using a well trained long short term memory network, which can capture the future trends of rooftop PV generations in a rolling horizon manner. With the information on PV predictions and DR results, a model free reinforcement learning method is developed for finding the near optimal dynamic pricing strategy. The simulation results verify the effectiveness of the proposed framework in making dynamic pricing strategies with partial or uncertain information.

Challenges in the low carbon adaptation of China's apartment towers
ABSTRACT Low carbon building retrofit will contribute to delivering China's policy to reduce carbon emissions. This paper proposes viable low carbon adaptation strategies for a recurrent building type within the Hot Summer and Cold Winter (HSCW) zone. An existing 23 storey tower in Hangzhou is investigated within the context of a representative city environment. Indoor air temperatures and energy consumption were monitored across a typical floor and simulated in EnergyPlus. Outdoor and indoor airflow patterns were modelled in an advanced computational fluid dynamics (CFD) tool, FLUIDITY. Across a typical floor, observations and modelling show marked variations. South facing flats overheat significantly in summer largely due to solar radiation. External sun shading structures are proposed and evaluated to counter summer overheating. An innovative wind catcher and exhaust stack natural ventilation system is proposed to enhance indoor thermal comfort using natural ventilation. Modelling of this integrated ventilation system indicates that the proposed retrofit system will improve indoor thermal comfort even in the lower floors. The proposed building retrofit strategy is costed using locally established construction cost estimates. Predicted energy savings suggest that the adaptation strategy proposed is potentially viable with significant implications for policy makers, developers, constructors and designers in this challenging climate zone in China.

The formation of the cost of overhaul of apartment buildings in the budget of the region
One of the main tasks in the formation of the regional program of overhaul is its cost estimate. In other words, it is necessary to know the amount of financial resources required for its implementation, both in the short and long term. The size of the marginal cost of work of common property overhaul in the apartment building, which is presented in the regional program, contains consolidated indicators of the overhaul of individual elements (types of work) of the apartment building. They are characterized by the presence of errors in their development and the general secrecy of information about the source data and methods for obtaining them. Currently, there is no base of enlarged estimated standards for overhaul, which are developed for objects analogues. These standards will allow to quickly determine the preliminary cost of the common property overhaul of the apartment building at the stage of implementing tenders, in order to optimize the amount of necessary and sufficient investments.

THE SERVICED APARTMENT SECTOR IN THE URBAN GLOBAL SOUTH: EVIDENCE FROM JOHANNESBURG, SOUTH AFRICA
The lodging sector is the focus of a substantial body of academic literature contributed from a range of disciplinary perspectives albeit mainly by hospitality management and tourism scholars. One form of lodging that has been somewhat neglected is the serviced apartment sector. This research investigates the development and characteristics of the serviced apartment sector in the urban global South with evidence drawn from Johannesburg, South Africa. The study analyses global industry reports, conducted an internet mediated audit of serviced apartments in South Africa and qualitative interviews with key property developers and other stakeholders in the Johannesburg serviced apartment sector. It is revealed that the character of this emerging lodging form in South Africa exhibits certain parallels with the global North. Serviced apartments cater mainly for business travellers and in particular visiting professionals on short term contract work assignments, a significant element of the changing nature of international business travel.
