In early September, the administration building Aviatica was inaugurated and officially unveiled, which is the flagship of a large development in the former factory Walter in Prague. Use of abandoned industrial sites, called Brownfields has been the great theme of Planning and Development during the last few years. Vast territories with dilapidated buildings have a negative impact on their environment, in terms of the degradation of the environment, environmental stress, negative social phenomena or reduction of the economic potential of the site. These lucrative localities are connected to existing technical and transport infrastructure. The transformation has a positive impact on the surrounding areas and instead of spatial expansion of cities into the countryside is one of the ways to exploit their intrinsic potential.

Methods of cost allocation in apartment buildings have undergone significant changes in recent years. The article offers a comprehensive overview of cost allocation methods in multi-dwelling units according to applicable regulations. It is intended mainly for owners of residential units, board members of homeowners associations, managers of housing cooperatives or individuals and companies managing residential buildings.
Cost allocation in apartment buildings is currently governed by two laws: Act No. 67/2013 Coll. and the new Civil Code No. 89/2012 Coll. These laws governed cost allocation in calendar year 2014 and apply also for 2015. The heating and hot water supply costs in MDUs from 2016 onwards will be allocated pursuant to the new decree No. 269/2015 Coll. and the amended Act No. 67/2013 Coll.

The basement of a castle greenhouse, so called catacombs, and a terrace with air shafts above them are located to the east by the Palm greenhouse of a state castle Lednice and they are connected with it. Catacombs used to serve as depositaries for storing plants from castle park in a period of winter month. Preservation of greenhouse’s catacombs began in 2004 and was carried out in phases till the end of 2007 when the work was interrupted. In 2012 the investor decided to proceed to finish the second part of a planned reconstruction connected with a reconstruction of basements under the greenhouse terrace. The vital part under the project documentation is also dealing with a rehabilitation of damp masonry including necessary constructional and technical research with respect to dampness and its elimination.

The recast of the Directive on Energy Performance of Buildings defined all new buildings will be nearly zero-energy buildings by the end of 2020. However, the transformation of the EU’s building stock will not be completed until well after 2020 and this target can only constitute an intermediate step. The renovation of existing buildings stock offers significant potential for both cost-effective CO2 emissions mitigation and substantial energy consumption reduction. Therefore energy efficiency can be seen as Europe’s biggest energy resource. The cost optimal methodology may be a useful tool able to identify the more appropriate retrofit measures in order to launch the renovation of the existing building stock on a large scale.

This paper describes an own development of a curtain wall panel system. The leading idea of the project was to prepare an alternative solution for replacement of old metallic curtain walls during the refurbishment of nonresidential buildings from the 1960ies – 1970ies. Presented solution use wood and wood based materials (laminated veneer lumbers) for construction of panels, with clear preference to non-oil based materials for thermal insulation. System allows for different type of external cladding (cement based boards, wooden claddings, integrated PV, support for greenery). Integration of other technical components, like venetian blinds, decentralized ventilation units, is possible. Thermal performance, noise protection and fire safety of this new envelope together with environmental oriented assessments are discussed.

In buildings registered in preservation zones the preservationists require keeping of the division and shaping of the opening pane girts and respecting of the original look of the facade. Keeping the girt profile, it is nowdays permitted to glaze the window wings using insulation glass. The manufacturers of windows still make many mistakes affecting not only physical characteristics of the opening panes but also their durability – life time.
