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 consequently 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.
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.

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.
Anyhow, the users were so satisfied that the owner, now expanding its business, contracted TECTO Arhitectura for a second office building, similar to this first one.
Building users opinion
“The Reci headquarter expresses credibility and confidence to all those visiting it. The image benefits are evident every time our partners praise the interior spaces having wide windows, effective ventilation and heating systems, which make us feel wonderful. Moreover, the spacious and properly equipped conference rooms give the premises for any meeting to be a successful one. On one hand, the building offers the optimum space for greeting partners and clients and, on the other hand, it also states the fact that the structure of the company is well consolidated, as the open space offices and their subtle organization encourage collaboration among colleagues and closeness to all facilities. ” (Adrian Radu, General Manager)
“The exterior combines the classical wood finish with our distinct shade of orange, in a linear geometry coming out of the green surroundings.
The structural solution puts emphasis on the specificity of our company, as the building sustains itself entirely on wood. Just imagining how working a day in such an office is can make one want to come work for our company. Besides, the atmosphere is so family-like! ”
(Katalin Sárkány, Head Accountant)
„The building creates a cheerful and warm ambience, which makes you think about nature. Also, the welcoming and serene interiors accommodate both effectively working and enjoyable breaks.”
(Anna Orosz, PR)
“What I like best about this building is the fact that it uses wood in a modern fashion. Many of the buildings in this area use wood as well, but none of them in a similar unconventional manner, making it unlike anything I have seen before. The wood pillars, beams and finishes complete the marble and glass surfaces, fashioning an impressive interior. ”
(Melinda Tunya, Accountant)

Project’s results
Specific annual energy consumption: 16.36 kWh/m2year
Specific annual energy consumption from renewable sources: 81.78 kWh/m2year
Heat Recovery Ventilation:
Required yield: maximum 6-7 shifts/hour.
CTA: maximum rated power 15,000 cm/hour.
Function:
The volume of cm/hour and the fresh air intake is automatically adjusted by the number of people (air consumption, CO2 sensor) and after cooling the rooms in summer.
Winter Heating season:
Theoretically: The heat recovery has a 80% efficiency at a nominal power of 15,000 cm/hour.
In real practice: The maximum volume reached an average of 6000 cm/hour, (40% of the projected power) with a 91% recovery of heating energy.
Summer cooling season:
Theoretically, the recovery system has a 30% rated output of 15,000 cm/hour
In real practice: The maximum volume has reached 9,000 cm/ hour (60% of the projected power) with a 45% recovery of cooling energy.
