In March 2014, Tecto Arhitectura was appointed to design the new office building for HSR factory in Reci, Covasna, as the first large scale project with CLT structure in south-east Europe. The main challenge was to create an office building for around sixty people that had to provide also an visual interface between two antagonistic spaces – an industrial platform used for production and a natural landscape with strong horizontal lines.
The project purpose was to design a flag-ship two-storey office building with a massive timber structure (according to the Austrian and Romanian building regulations), that follows also the standards for Multi Confort criteria (according to the guidelines enlisted by Saint Gobain). Nevertheless the project strategy was based on utmost ecological and long-term sustainability.
The team work between Tecto Arhitectura, the client and the project partners was to create an office building typology based on ecological and long-term sustainability as demonstration project and conseqently to establish it in the market-financed office building market. The design work-flow followed four major objectives:
Mix timber construction: massive timber construction and glue laminated elements, industrially produced prefabrication.
Standards for Multi Comfort from Saint Gobain: individually room-controlled comfort and high-quality work environment, increased noise protection, passive construction method for insulation and airtightness, ventilation system with heat recovery.
Ecological concept: use of geothermal energy and high efficiency biomass cogeneration plant for heating and electricity, timber construction, optimization of utilities costs, green roofs, enhanced daylight autonomy, increased degree of recyclability for the entire building.
High quality architecture and landscape.
The rather ambitious goals set by owner in general as well as the additional provisions foreseen by the modules of subsidy could be realized to an even greater extent. From the current perspective - subject to the short operation time – it can be said, that the project has been a great success. Besides that, the building was subject of various site measurements, tests and evaluation of users’ satisfaction.
More than that, the office building has a very good energy efficiency, the energy certificate issued having a specific annual energy consumption (kWh/m2year) of 16.36 and a emission index equivalent CO2 (kgCO2/ m2year) of 1.22.
Already during the project development, a close cooperation between the partners was established. Without such engagement – also from the involved authorities, planners and builders, systems providers – at present it would not be possible to realize comparable projects and competitive construction costs. Therefore, such projects should be still considered as demonstration projects and analysed from this point of view.
