Jetrun EnergoEco commissioned the HVAC equipment at Artifex, a textile manufacturing plant in Focsani, Romania.

 In 2012 , Artifex started the total renovation of a 13 500 m2 working space, located in Focsani. The production process involves various types of activities , each activity requiring a different microclimate . A common essential element is the need for a strict control of the humidity level. The client wanted a system that provided energy efficiency and a high level of comfort for the employees, which became a challenge for the whole team who worked on the project: the design company Cepronef, the execution company Amteh and the equipment supplier Jetrun EnergoEco.

 

“The project requirements regarding energy efficiency and a high level of comfort have increased the complexity of the system and asked for a creative approach . We opted for implementing a geothermal heat pump solution, creating one of the largest industrial projects that use geothermal energy in Romania . We decided to follow the operating parameters of the system to develop a practical knowledge base in this area which is less explored in our country. ” said Adrian Moisa, general manager at Jetrun .

 

The ventilation system is made up of 4 air handling units Wolf KG Top 510 of 40,000 m3 / h with rotary heat recovery system and KG Top 190 of 10,000 m3 / h with plate heat recovery . Given the high density of employees, it is important to ensure a consistent volume of fresh air without affecting the overall efficiency of the installation. The heat recovery system benefits from a special treatment to ensure humidity recovery from the spent air, an extremely important function to reduce the need for additional humidification in winter. As for increased comfort for the employees, we opted for underfloor heating and cooling. By reducing the heat and cooling load of the ventilation system, we can reduce the difference in temperature between the introduced fresh air and the air inside the room, thus eliminating the discomfort created by conventional systems for heating / ventilation .

 

The air introduction piping was made ​​up of textile fabric and the exhaust air system was made up of metal. To ensure the thermal load for heating and cooling , Jetrun delivered 4 reversible geothermal heat pumps of 250 Kw each, with multiscroll technology and intelligent cascading kit, produced by Hiref . The heat pumps extract heat from a geothermal field of 120 wells of 120m depth and covers the entire heat demand of the building. At a COP 4.0, the primary energy consumption is reduced 4 times compared to a standard system .

In the last meeting that took place in late February at RoGBC headquarters, it was establish what needs to be done to finalize the MEP project for the ecoBiblioteca project according to the new changes in the RoGBC design team.

As you know from previous posts, the ecoBiblioteca project will implement, for the first time in Romania (and in Europe) the Living Building Challenge ecological certification, which is the most accurate system for ecological building certification existing in the world. To be eligible for certification, Living Building Challenge requires that the building should be, between others prerequisites, a zero energy building – that means a very high performance envelope of the building and most energy efficient MEP systems and equipments.

According to the technical MEP project, designed by CUNDALL, the RoGBC member JETRUN, provided on the ecoBiblioteca project high performance equipment for heating system and for ventilation system, respecting Living Building Challenge requirements:

– the heating generation design system will be provided by VITASTAL, using a heating pump with borehole soil to water collection. Also, Vitastal will provide expertise in Net Zero Energy prerogative requested by Living Building Challenge certification.

– the distribution of the heating agent and the ventilation ducts will be provided by Thermaflex with duct that respect Living Building Challenge material prerogative.

– The heating system will be with CLINA radiant surfaces at low temperatures (max 30 C) through the ceiling. The design, consultancy and material would be provided by PROMAX Engineering – CLINA Romanian representatives.

– The lighting system design by B-lighting and the fixtures are be provided by our partners OSRAM.

The coordination of mechanical and electrical installation, as well as the implementation on site would be provided by our recent member DAS ENGINEERING GRUP, through its representative dipl eng Alexandra Stoica.

The new member of RoGBC, EGEEA Design, has made on 13 December 2012 an survey with a infrared camera of the RoGBC headquarters. As part of the RoGBC pilot project : Greening our Workspace Phase II.

The survey has revealed the main areas where the heat transfer is increased, know as Thermal Bridges. Areas which, besides the energy which is consumed (lost) to the exterior environment, they can develop mold and/or condensation on the interior finishing and also, more evident, they generate a thermal discomfort of the residents.

Below you can find some images from this survey.

Exeterior view: the darker parts of the attic is covered with snow, the lighter  parts o the attic are thermal bridges which are dry(not covered whit snow) due to the interior-exterior heat transfer.

[1] The Leadership in Energy and Environmental Design program from the United States Green Building Council is a means for building owners to certify their building as a sustainable facility. The program allocates credits to different categories of sustainable design and provides a Certified, Silver, Gold, or Platinum rating based on the number of credits obtained.

Termaflex – reliable partner for Green Buildings

Thermaflex company has been actively involved in “Green Library” project, providing non pollutant solutions that can ensure energy loss reduction and implicitly the decrease of CO2 emissions.

To ensure the link between the technical room and the library building, there have been used 2 pre-isulated pipes Flexalen 600, De 32mm, return pipes with a total length of 15 meters. The main pipe, made of polybutylene (Polybutene PB1) provides a life-cycle of more than 50 years, for temperature of maximum 95 °C, and assures lasting properties over the entire exploitation period at a pressure of maximum 8 bars.  The pipage covering is made of polyolefins foam with closed cells that provides a thermal conductivity  of less than 0,032 W/mK. Due to its cellular structure, the covering blocks water absorption. Having a high flexibility and being a heat-sealable material, the installation price is very low, in comparison with classical systems.


For thermal energy distribution inside the building, there will be used polybutylene pipes with a diameter of 16 and 20 mm, covered with thermal insulation, Thermacompact  type. Both insulation and pipes are 100% recyclable and do not contain environment-unfriendly substances. The pipes and fitting pieces can be welded, so the resulting system is homogenous and very reliable.

Thermacompact insulation is made of polyolefins foam, having a red  co-extruded  membrane on the exterior. This membrane gives good physical properties and can be fixed in masonry or screed.

All the materials recommended for this project have been carefully analysed in order to match the ecological requirements and to ensure the transport and thermal energy distribution with minimum loss.
