This is an estimation of the life cycle cost (LCC) of Japanese wooden detached houses. From a questionnaire research, we calculated the survival probability of various part of a house and remaining rate. The years of 50% remaining rate is taken as a standard repair interval to make a simulation model of life cycle refurbishment of a house. The refurbishment cost was estimated from interviews to the professionals or the analysis of real cases. Applying them to the simulation model, LCC of 30 year life is estimated to be 2.16 times of new construction cost, and that of 60 year life is 3.25 times.

The number of enterprises that offer the Property management business as the real estate investment maket for recent years grows up increases. A corporate number that was 100 companies in 2002 reaches about 450 companies according to the investigation in 2008. This research investigates the amount of the business of the property management business in the real estate for the investment and the actual condition of the work contents. And, the structure of corporate profits of the property management business is clarified and the evaluation approach of the business is examined.

<p> In this study, we analyzed the transition of building stock in the Tokyo wards and visualized the results. The data we used are the GIS databases created by Tokyo Metropolis, which correspond to six time points every five years from 1991 to 2016, and the analysis proceeded as follows.</p><p> 1) Data screening: In order to analyze the GIS data across the years, data screening is needed. We unified the definitions of attribute data and excluded data with missing values and outliers. In addition, since it was confirmed that some divided polygons were contained in the data, then we combined them into the ordinary forms.</p><p> 2) Basic statistics: During the 25 years, the gross floor area has increased by 60% against the 8% increase in the number of buildings, and the average size of the buildings has increased by 48%. However, as for the median, the increase is only 14%. The other quantiles did not change significantly compared to the average value. This may be resulted from the hugeness of some new buildings and indicates that the unevenness of building scale distribution in urban has increased year by year. Also, looking at this from the view of use, the commercial buildings have a strong trend to be large scale, as well as the offices and the apartment houses, while the average gross floor area of detached houses is almost constant. Also, the distribution of gross floor area of detached houses is found out to be converging on around 138 square meters (that is calculated from polygon data and is different from the exact floor area). The changing trends of building size were different depending on the building use.</p><p> 3) Comprehension of building state changes: In order to comprehend the change of the state of a building, the GIS data of 2010 and 2016 were spatially overlapped and the identification of buildings were implemented, then we extracted the buildings seemed to be not same as before. As the result of overlapping, the change patterns of building state were classified into six types, as "Rebuilding", "New Construction", "Demolition", "Integration", "Division", and "Other". Comparing the change of building size by patterns, there was a remarkable trend of enlargement in "Integration" and miniaturization in "Division". "Integration" shows higher proportion than other patterns in the commercial buildings, the offices and the apartment houses. On the other hand, most of the "Division" was occurred in the detached houses. It is considered that these results are related to the transition of the total floor area of each building use.</p><p> Looking at the geographical distribution density of building change patterns using kernel density estimation, the "Demolition" and the "Integration" had high density mainly in the downtown area, and the "Division" was distributed mainly in the residential area. In addition, the "New Construction" occurred at the outer edge. The huge buildings are thought to appear caused by the "Demolition" and the "Integration" around the center area of the city. In addition, it is also suggested that the living environments are changing as "Divisions" are actively carried out in old residence towns.</p>

&nbsp;In this research we conducted a long-term survey of the actual states of repair construction on buildings. From the investigation, we estimate the most suitable renewal cycle of the parts and equipment in buildings. If we know the appropriate renewal cycles of major parts and equipment in buildings, we can keep buildings in good conditions for long time.<br><br>&nbsp;1) In the first half of the analysis, we surveyed the current situation of repairing works conducted on 668 buildings. Preventative repair works are periodically carried out, however it was understood that the number and the cost of reconstruction after the malfunction takes much more proportion than those of preventative repair works.<br>&nbsp;2) In the middle stage, we researched the reliability and the failure rate of various part and equipment in buildings and estimated long-term tendencies. The rough life span of the building parts and the types of equipment were estimated from the calculated reliability functions. It was made clear that the life spans of them are almost about 30 years. The failure rate gradually increased a little around 15-20 years after completion.<br>&nbsp;3) In the final section, we used the total maintenance costs, calculated by the failure rate and the failure risks, and estimated the most suitable renewal cycle of the parts and equipment in buildings. As a result, it turned out that the failure risk has a large impact on the determination of the optimal renewal cycle. As for the electrical equipment, the suitable optimal cycle is around 20 years when the failure risk increases threefold. It will be around 15 years if the failure risk increases tenfold.
