The construction industry produces 25 to 30 % of greenhouse gases and consumes 40 % of globally required energy. The construction industry and buildings contribute significantly to the climate change. Also the buildings are the cornerstone to the public space and affect its quality. One of the approaches to reduce greenhouse gas production (especially carbon dioxide) is the construction and operation of buildings according to the principles of sustainability. Houses are mostly not certified (environmental certification programs as LEED or BREEAM) because it is uneconomical to certify. However, the houses can fulfill sustainable construction aspects like using natural or recycled materials, design of energy efficient buildings, using alternative energy sources, connection to public transport, etc. The influence of using basic sustainable principles and quality of public space as an important part of sustainability to a price was tested through a database. The database consists of 98 samples of houses sold over the year 2017 in Brno - venkov district. Significant price settings factors were identified. Due to the number of variables, testing by multivariate regression analysis was performed on submodels, individual variables could be correctly identified. Tested database confirmed basic price setting factors for houses, such as the technical condition of the house, distance from the city of Brno, as well as the useable area of the house and the factor of liquidity. The influence of sustainable principles like using renewable energy, low energy demand, solar panels for hot water or photovoltaic panels was rejected. Some kind of sustainable principle was detected at 10 % of samples. Material base, especially using natural materials like timber, was not found as a price setting factor. One of the submodels was focused on the social part of the sustainability given to the location and public space. The possibility of using public transportation or car park close to the house was not confirmed as price setting factors affecting the price. Also the danger of flooding, index of criminality and noise level were considered and were rejected as price affecting. This paper presents results aimed at exploring the importance of the basic aspects of sustainable construction and quality of public space on the price of houses in the database of 98 houses in Brno - venkov district, Czech Republic.

Purpose This study aims to provide a framework for assessing the technical condition of a house to determine its market value, including the identification of other price-setting factors and their statistical significance. Time on market (TOM) in relation to the technical condition of a house is also addressed. Design/methodology/approach The primary database contains 631 houses, and the initial asking price and selling price are examined. All the houses are located in the Brno–venkov district in the Czech Republic. Regression analysis was used to test the influence of price-setting factors. The standard ordinary least squares estimator and the maximum likelihood estimator were used in the frame of generalized linear models. Findings Using envelope components of houses separately, such as the façade condition, windows, roof, condition of interior and year of construction, brings better results than using a single factor for the technical condition. TOM was found to be 67 days lower for houses intended for demolition – as compared to new houses – and 18 days lower for houses to refurbishment. Originality/value To the best of the authors’ knowledge, this paper is original in the substitution of specific price-setting factors for factors relating to the technical condition of houses as well as in proposing the framework for professionals in the Czech Republic.

The article deals with 11 th JuFoS 2019 conference. The conference was held at the Institute of Forensic Engineering at BUT on April 11, 2019. This year's conference was attended by 34 participants from the Czech and Slovak Republics.

Problematika oceňování dřevostaveb je ve znalecké praxi čím dál tím více diskutovanější, také vzhledem k tomu, že se výstavba dřevostaveb rok od roku zvyšuje. Článek obsahuje přehled jednotlivých konstrukčních systémů především se zaměřením na různé technologie výstavby. S problematikou ocenění dřevostavby rodinného domu se znalec/odhadce může setkat v různých fázích životního cyklu této stavby. Proto se článek zaměřuje na využití různých metod ocenění v předinvestiční a provozní fázi životního cyklu stavby. Dále se článek zabývá pořizovacími náklady dřevostaveb v závislosti na použité technologii a zároveň přináší doporučení, jakým způsobem reflektovat tyto rozdíly do stanovení tržní hodnoty resp. ceny obvyklé.

The construction industry has a significant impact on the environment, and it especially affects the level of greenhouse gases. It also reduces the greenhouse gases through constructing and operating sustainable buildings. Sustainable buildings include buildings that meet basic sustainable principles, namely environmental, social, and economic. Sustainable buildings are very often associated with certified buildings (LEED, BREEAM). However, sustainable buildings do not have to be certified to fulfill the idea of sustainability. The question is, how much does sustainability affect the selling prices of houses. A database of 570 sold houses in the district of Brno – venkov in the period of years 2017 - 2019 was compiled. It was found that 5.6% of the houses featured some sustainable aspects, such as heat recovery systems, natural construction materials and all alternative technologies. The factors of liquidity were considered and evaluated. In case of the sustainable houses 3.0 % higher ΔP (difference between asking and market price) was detected. Influence on time on the market was not proven. Based on ANOVA analysis, the impact of sustainable features of houses on the selling prices was not found. Analysis was carried out by a semi-database of 122 houses sold in the year 2017.
