Meeting the acoustic challenges of data centers

Data centers generate constant noise from air conditioning, ventilation and cooling systems (chillers, extractors, AHUs, etc.).

Generators are also an integral part of a data center, acting as back-up systems in the event of a main network failure. They are very noisy, up to 130 db(A).

Dealing with noise is essential to improving comfort at work and minimizing harm to the environment. For example, the noise generated by ventilation systems on the roofs of data centers is often significant and can create a real nuisance to residential third parties. 

At F2A, we offer acoustic solutions dedicated to data centers. We design and manufacture specific equipment to effectively reduce noise, such as acoustic absorbing screens, acoustic louvre screens, silencers, acoustic hoods, caps and vibration damping systems (anti-vibration).

We tailor our solutions to the needs of each data center to ensure optimum noise reduction and maintain equipment performance. Reduced noise levels can also extend equipment life by limiting harmful vibrations.

Silence… filming at F2A!

F2A wins GREENLY silver medal!

We’re delighted to announce that we’ve been awarded a silver medal by the independent organisation GREENLY !

This medal complements our commitment to Corporate Social Responsibility (CSR) and our progress in reducing our carbon footprint over the last two years.

Reducing our GHG emissions

F2A has launched its second carbon assessment for 2023 and has chosen GREENLY, a world-renowned platform that assesses companies’ greenhouse gas emissions using a methodology validated by the French Ministry for the Environment and ADEME.

The 2023 result is 19,400 tCO2e for all scopes 1, 2 and 3.

Thanks to an ambitious and collective climate strategy, we have reduced our greenhouse gas emissions by 9% between 2022 and 2023, from 0.64 ktCO2e/M€ in 2022 to 0.59 ktCO2e/M€ in 2023. This performance is the result of :

• Purchasing and using less emissive raw materials: the glass wool used to make our baffles is less emissive than rock wool.
• Our energy-saving plan: replacing a gas boiler with a PAS (heat pump), heating temperatures, turning off machines during breaks, etc.
• Optimising our material waste
• Optimising our transport
• Improving our waste management: re-use, reducing CIW and hazardous waste, recovering our wool waste, etc.

Environmental commitment

F2A has been committed to environmental protection and ISO 14001 since 2013.

For the past two years, F2A has been actively involved in reducing greenhouse gas emissions in line with the objectives of the Paris Agreements. Our commitment includes our entire ecosystem, from our employees to our suppliers and customers.

This second silver medal testifies to our ongoing efforts and determination to improve our environmental impact.

PREMIUM+

Comfort in buildings also involves the acoustic quality of workplaces.

Today, many commercial building employees are subject to technical equipment noise pollution which bother, tire or distract them. To reduce spead noises in ductworks mostly circular, by aeraulic components (dampers, backdraught dampers…), an effective silencer as the premium + is needed.

PREMIUM+ :

• The most effective circular silencer on the market now available up to a 1500 mm length!
• It easily integrates in false ceilings thanks to minimum space requirement.
• Anti-defibration protection (fiber glass fabric) option adapted for areas with high requirements.

Indoor air quality

Indoor air quality is important for many reasons, starting with the health of the occupants.

Today, for large-scale energy savings, ventilation must adapt to real needs and to intermittent occupancy (classrooms, offices, conference rooms) or become intermittent with teleworking for example. Thus, premises are never used 100% of the time and to 100% of the capacity.

In this documentation, find the most comprehensive solution of the market, presented in 4 packages, adaptable to all projects with, in addition, products of new generation, easy to install.

Grand Paris Express – Episode 2

Did you know that? F2A resists the earthquake

Did you know that?
Some ductworks are Equipment Important For Safety. As such, they must withstand to aggressions such as earthquakes.

According to their safety classification, they must:

• Either preserve their integrity during the earthquake, and their operability after the earthquake.
• Or maintain their operability during and after an earthquake.

Ventilation systems are a key point in the safety of installations in case of an earthquake in a nuclear Installation (INB).
Ductworks contribute to confinement, cooling and are essential to guarantee air renewal and good thermal conditions, even in accidental situations. The design and validation of the equipment’s ability to resist such scenarios is at the very heart of the requirements in force in the nuclear field.

Through its references of dampers and backdraught dampers dedicated to the nuclear field, F2A shows its expertise to perfectly meet the safety requirements.

Last January, our ARE backdraught dampers, and our CI shut-off dampers designed to withstand earthquake were tested in the Virlab laboratory. They will be installed by EQUANS teams as part of the large RJH project for the French Alternative Energies and Atomic Energy Commission (CEA).

Congratulations to the F2A air management and nuclear teams!
Thanks to BLUE.ENG and VIRLAB teams who supported us throughout the qualification process.

Interventional and Surgical Centre (ISC)

After the metro line B in which F2A took part, the construction of the new teaching hospital will be undoubtedly the biggest building site of these past years in Rennes.

Data Centers issues

This week, highlight on one of our recent French data center projects.

Computer servers and data storage equipment, at the heart of data centers, create heat where cooling becomes the main concern.

More than a third of their total energy consumption is dedicated to cooling. An air circulation must be set between the hot air exhausted from the servers and the return air duct of the air conditioning unit.

From the design of the data center, our engineering department was involved in finding a global solution from the air intake to the distribution, from the air circulation to the recycling, for a cooling system by fresh air on the server rooms.

Our ME industrial dampers specially designed for large section ductworks were particularly well suited to handle the ventilation of computer servers. As this room is very sensitive, the 4C airtightness class was required in order to isolate the room in case of contamination from the outside air.

Performances tested in an independent laboratory

For many years, the performances of all our silencers and dampers have been tested in an independent laboratory. Thus, the data we provide are given in the strictest impartiality.

The CTTM performs all acoustic tests on our equipment : regenerations, pressure losses and attenuations of silencers.
We collaborate closely in R&D, especially for researches to improve the performance of our splitters and the NF ISO 7235 test standard.

CTTM has two coupled rooms, a semi-anechoic room and a reverberant room, where a wide range of experiments can be carried out under excellent conditions (very low background noise, large volumes, low frequency measurements,etc…). This rooms coupling of about 1000 m3 is unique in France.

See how characterizations, diagnosis and measurements of our equipment are performed !

Discover our acoustic factory !

Tunnels and metros expertise

Traffic can reach up to 200 000 vehicles a day in a road tunnel and the safety of users is a major issue. A fire taking place in a tunnel can have awful consequences.
The same risks with the same consequences can occur also in a metro carrying passengers.

Acoustic in tunnels is the other main issue to handle in regards to both users and neighbours.
The noise level inside must be low to allow users to hear to the fire alarm and people to work properly. The surrounding outside noise must be limited not to bother neighbourhood.

Indoor air quality from high school to kindergarden

Face-to-face classes resumed on Monday, May 3rd for middle and high school students after a month of holidays and e-learning. This school start is marked by a strict health protocol and in this time of half-occupancies and self-tests, air quality in classrooms is also a must.

A diagnosis IAQ is mandatory in french nursery, kindergartens and preschools since  January 1st, 2018 and is also became compulsory  for middle-school and high schools since the 1st January 2020. At a time when news positionne indoor air quality in everyone’s concern, F2A offers simple and effective solutions to improve air quality in public buildings, especially schools.

Variable air volume systems guarantee an air renewal that is constantly optimized in relation to the occupancy of the classroom. For 2 years now, Jacques-Yves Cousteau school group in Genay (France) has thus been equipped with RCVS variable air volume dampers controlled by C0²  sensors to ensure hygienic fresh air flow according to the carbon dioxide content. The whole equipment was provided by F2A.

The Espace Tourbillon

New reference F2A !

The Espace Tourbillon is a huge urban development project located in Plan-les-Ouates, just ouside Geneva. It offers 95,000 m² of usable area spread over five seven-level buildings and includes a underground logistics terminal.
A major project and one of the most recent major construction sites in Geneva, the complex favors logistical aspects, while at the same time providing a pleasant “village” type working environment.

The objective is to supply and produce for the 5 buildings a wide range of high airtight products both on the air management part, as well as on the acoustic part, and manage the requirements of the strict 4-year delivery protocol involved by such a huge project.

As part of its customer Engie Techniques SA’s, ventilation package, F2A manufactured and supplied nearly 2000 elements dampers or silencers, of which 642 flexible connections !

PREMIUM range

Acoustic in work places (offices, public access buildings…) and residential buildings is one of the main criteria of the comfort in a building.

Many commercial building employees who are working in open spaces are rarely exposed to injured noise level. However, they are subject to technical equipment noise pollution which bother, tire or distract them.

Acoustic treatment in ventilation ductworks is not only a matter of acoustic silencer before or after the air handling units. It is important to add silencers in terminal part of the ductwork to reduce the noise regenerated by connections and aeraulic components (dampers, backdraught dampers…)

The PREMIUM range is the most suitable with its impressive acoustic performance while easily integrating in  false ceilings thanks to minimum space requirement (the smallest : L 275 mm x H 180 mm).

Our strength, our production capacities

Today, close-up on our dampers and weather louvres factory located in Saint Ouen sur Iton (61).

Since the beginning, the F2A group has chosen to capitalize on its production plant as well as its air management design office in the industrial area of of l’Aigle (Normandy), to take advantage of a French workforce trained in the industry field and of local suppliers.

In this plant, for almost 25 years, a team of specialists has been designing and manufacturing custom-made ventilation solutions for air management ductworks and smoke exaust, dedicated to the commercial buildings, tunnel and metro, marine, oil and gas and nuclear markets.

This is why we now have a very large production capacity that enables us to meet the specific requirements of these markets.

Air management is a highly technical job and we invested in the training of all our production staff from the very begining. Our teams, composed of qualified production technicians and project managers, have skills and knowledge that allow us to maintain this beautiful production tool in perfect condition.

The VAV benefits ?

At the time of the massive telework development, the habits of ventilation need to be rethought.

Implementing effective actions to modulate the operation of air management in the premises while respecting the health requirements and adapting to the real occupancy of the buildings can lead to significant energy savings.

Increasing fresh airflow only when and how the building is occupied must comply with the requirements on energy savings. However, capitalizing on under-occupancy of buildings is possible and requires a good knowledge of the operation of the ventilation system.

F2A variable airflow dampers, whether circular and connected like our latest e-VAV, or rectangular, can meet these requirements.

We have developed a range of variable flow systems for fresh air in all buildings. This range allows to adjust the ventilation to the real needs to optimize comfort and energy, as well as to ensure the hygienic air flow according to carbon dioxide level.

The VAV systems enable to control the temperature and the indoor air quality but also to balance the pressure in complex ductworks or buildings with several levels when the dampers are set to control a constant pressure in the duct.

Advantages : 

• Temperature control
• Air quality control
• Pressure control
• Analog or communicating actuator
• Class 3C airthightness dampers according to EN1751
• Available in circular or rectangular version
• Acoustic casing available in option
• Galvanized steel construction : RCVS and RRVS
• Connected and energy self-sufficient : only  e·VAV

MCE circular artight sleeve

MCE circular artight sleeve : airtightness and energy savings !

The airtightness class of a ductwork system, according to the NF EN 12237 standard, depends on all the elements of  the ventilation system. The flexible connections must be taken into account in the measurements of the leakage rate of a ductwork, otherwise a penalty coefficient will be applied according to the FD E-51-767 operating process.

MCE circular airtight sleeve, class C according to EN 15 727 (leakages divided by 9 compared to class A), guarantee the initial tightness class of the ductwork and enable to connect with reliability fans or air handling units to the ductwork.

The MCE has been developed to reduce energy losses from buildings by significantly reducing leakage rates. Finally, the integrated clamping ring clamps ensure a quick and easy installation.

Heating or cooling mode ?

No compromise, Texi Move optimizes the 2 modes individually.

In all static HVAC system a compromise between heating and cooling mode is always needed.

Back on the Alto Tower project

Last year, we report to you our participation in this new project in the landscape of the La Defense district neighborhood that is the Alto Tower. 3 weeks ago, our team completed the last step of this project with the measurements of verification of the sound objectives requested by the engineering and design department of the Cap Horn project management.

Office floors, annexes, future sports hall, VIP area as well as the parking fans, everything was precisely controlled on site by François O., one of our F2A acoustical engineers, thus confirming the expertise of our design office in the solutions proposed for the optimization of noise level reduction inherent to the 76 Air Handling Units of the structure.

The Alto Tower project is part of the 4 Saisons district renovation.
The glass scale of its surface will consist of 17 500 m2 of double insulating skin. Launched in September 2016, the building site of the 51,000 m² tower with 38 floors and 2 large terraces offers today an extraordinary flared shape, from 700 m² at the base to 1,900 m² at the top . Being “perfect” in terms of environmental performance is Alto’s successful bet imagined by IF Architectes.

The glass scale of its surface will consist of 17 500 m2 of double insulating skin.

Launched in September 2016, the building site of the 51,000 m² tower with 38 floors and 2 large terraces (including a VIP one) offers today an extraordinary flared shape, from 700 m² at the base to 1,900 m² at the top .

Being “perfect” in terms of environmental performance is Alto’s successful bet.

By aiming the highest levels of certification, HQE® Exceptionnel, Wellcore shell silver level and BREEAM®, level OUTSTANDING Alto will be one of the most energy efficient with its insulating facade and huge work in HVAC.

The construction site is an example, as architects and builders had to adjust the building design to the structures already there on one hand and the low noise levels required  by the project management team on the other hand.

With 2 goals :

• Reduce the external noise level generated by the 76 Air Handling Units, chillers and exhaust fans, thereby protect the First Tower (La Défense’s icon and one of the most emblematic buildings) in close proximity.
• Optimize the comfort of future occupants and visitors to the tower, especially the coming Skylounge space (VIP).

F2A solutions:

All the expertise of the F2A acoustic research department has very accurately certified calculation notes of the silencers to be installed on the Air Handling Units floors of offices, annexes, future sports hall as well as the parking fans.

For an optimized solution to reduce the noise inherent in an Air Handling Units, our acoustic engineers have specified acoustic splitters and silencers BS + and BD and provided technical assistance throughout the study and execution phase.

Finally, an acoustic 3D mapping was carried out for the verification of the equipment impact located on technical terraces of the VIP outdoor space thus validating the noise levels required by the project management team Cap Horn.

Indoor air quality from kindergarten to high school !

The Elabe-Veolia survey, carried out on September 3rd and 4th, still highlight it, 9 out of 10 French people find a direct link between the Indoor Air Quality of schools and the health of students.

Read the survey

A diagnosis IAQ is mandatory in french nursery, kindergartens and preschools since  January 1^st, 2018 and will also become compulsory  for middle-school and high schools from the 1^st January 2020.

At a time when indoor air quality is becoming everyone’s concern, F2A offers simple and effective solutions to improve air quality in public buildings, especially schools.

Variable air volume systems guarantee an air renewal that is constantly optimized in relation to the occupancy of the premises.

This in mind, the Jacques-Yves Cousteau school group in Genay (France) will soon be equipped with RCVS variable air volume dampers controlled by C0²  sensors to ensure hygienic fresh air flow according to the carbon dioxide content, the whole of the equipment being provided by F2A.

Our technical and commercial teams are at your disposal to support you from design to commissioning.

BIM Summit

Today BIM&CO international collaborative platform organize its first day of exchanges for contractors and building product manufacturers to structure and distribute their data to all AEC players devoted to building process improvement to each step of the construction site.

As F2A Marketing Director Julien Musset will take part of it at noon to discuss about how manufacturer content are at the core of designers needs.

Contractors need from manufacturers not only geometrical information but also structured and reliable data for the design, the construction and the operation stages of a building. BIM ‘s aim is to make the various trades involved in a construction work together, the collaboration being carried out around a digital model, virtual twin of the building to be built.

F2A choose 1 year ago to offer this smart library service for its dampers avoiding to re-key information between different actors, problems detection before the work site starts, saving time in simulations and increases accuracy in engineering calculations.

ISAVFT 2019

Tomorrow and until September 27th, the ISAVFT 2019, an essential appointment for tunnels and metros operators, opens its doors in Athens.

F2A is taking part once again to this major event.

We will expose our know-how and dedicated solutions for smoke extraction in case of fire and noise control in a tunnel.

Tunnel Expertise

Traffic can reach up to 200 000 vehicles a day in a road tunnel and the safety of users is a major issue. A fire taking place in a tunnel can have awful consequences.

The same risks with the same consequences can occur also in a metro carrying passengers.

Acoustic in tunnels is the other main issue to handle in regards to both users and neighbours.

The noise level inside must be low to allow users to hear to the fire alarm and people to work properly. The surrounding outside noise must be limited not to bother neighbourhood.

Splitters with external membrane, 4 questions to the expert François Fohr

1) You have performed comparative tests between standard acoustic splitters and external membrane splitters. Can you first enlighten us on their respective conceptions ?

The standard splitters consists of a simple plate of fibrous material of a certain thickness placed in the direction of the air flow. The two faces of the plate constitute acoustic absorbers which make it possible to attenuate the noise transmitted in the ventilation duct. The complete silencer consists of a set of parallel splitters and its efficiency depends on the thickness of the splitters and their spacing (airways). Generally, these devices make it possible to achieve very good attenuations in the medium and high frequencies bu are poorly suited to low frequency treatment.

The external membrane splitter is presented as a solution to compensate for this performance deficit in the low frequencies but it turns out that it is quite little verified in practice. Its design is based on the addition of a metal plate concealing half of each side of the splitter, these plates being placed in staggered rows. By design, this principle deprives the splitter of half of its absorbent surface, which is reflected in the performance measured in the medium and high frequencies. In the field of low frequencies, the performances are very dependent on the spacing between the splitters (ariways). It is only for very small spacings that the performances really become superior to the classic splitters. But this concerns implementation conditions that are very unfavorable from the aeraulic point of view since they are accompanied by high pressure losses.

2) What types of measures have been taken and on what type of equipment ?

The different test campaigns that we have been able to carry out on these two types of splitters have been conducted on a test bench complying with the recommendations of he ISO 7235 standard which is the reference in this field. In addition, for the very particular low frequency domain, we have also carried out additional measures to overcome the high uncertainties of the standardized method. These complementary methodologies have been published in particular in the journal “Acoustique et Techniques”.

3) What are your conclusions ?

Based on the comparative measurements we have made and the understanding we have of the acoustic principles involved, it is quite clear that external membrane splitters do not represent a truly effective solution for improving the attenuation of low frequencies. As they also lose some of their efficiency in medium and high frequencies, the balance is rather negative.

4) Is there a real solution to attenuate the low frequencies ?

Today, there is no specific solution to the problem of low frequencies. In practice, the only option is to use thick splitters installed in large silencers so as to preserve a passage of air sufficient from an aeraulic point of view.

Airtightness of air handling systems

The question of the airtightness of air handling systems.

Today, the airtightness quality of air handling systems is taken into account in French thermal regulations, in the same way as large number of other parameters. This is the opportunity for F2A to reiterate a number of data and to present its new airtight circular sleeve.

Improvement in the airtightness of the air handling systems equipping individual, collective and commercial buildings is a must for reducing energy consumption while preserving hygiene and air quality inside rooms. To achieve a good airtightness results.

Risks on Oil Rigs

Oil & Gas rigs house a lot of highly combustible chemicals and gas, which means there is a high risk of fire or gas explosion. These kinds of incidents happen suddenly and often without warning. It is important to be ready by having all possible preventive measures in place.

Extinguishers and suppression agents should be easily accessible. The areas of greatest concern are: gas chambers, oil tanks and electricity rooms. All machinery and equipment should be inspected on a regular basis. Regular inspection and maintenance can reduce the risks of potential explosion or fire. Employees should receive proper safety prior to starting their position if they work in area where highly combustible material is present or there is a risk of fire.

Another danger is the exposure to chemicals. If toxic chemicals are released into the atmosphere, workers can experience respiratory issues from prolonged exposure. Many oil rigs release high levels of Hydrogen Sulfide, which can cause paralysis, cancer, or death from too muche exposure.

Major accidents can be disastrous for people and the environment. The highest quality products must be used in order to avoid such accidents. F2A has custom solutions for this market that are ATEX certified.

Smoke extraction : regulation point

The current European standard EN 12101-8 specifies the basic performance and requirements for smoke extraction dampers to be used with pressure differential systems and smoke and heat control systems.

The product standard EN 12101-8 is supplemented by two other standards defining the tests and classification of smoke extraction systems.

• EN 1366-10: fire resistance tests
• EN 13501-4: fire resistance rating

The smoke extraction damper is subjected to extensive tests of mechanical strength and leak-tightness at several temperatures and pressures to determine its classification.

Unlike the multi-compartment application (extraction or ducts serving several compartments), the “Mono-compartment” application, extraction or flue extraction line is directly connected to the outside without being in contact with another compartment.

The new MSD-F register meets European requirements for single-compartment smoke extraction applications.

MSD-F ranking according to EN 13501-4 :

The MSD-F is equipped with an all-or-nothing actuator protected by a thermal jacket. It can be installed vertically or horizontally, as a wall or as a recess. The smoke exhaust damper MSD-F meets the requirements of a CE marking.

Smoke exhaust damper MSD-F – EN 12101-8 certified

A smoke exhaust damper is an automatic or manual ddevice which can be opened or closed in an operational position, allowing control of the flow of smoke and hot gases to, from or into the ductwork.

Smoke control systems are designed to fulfill the following functions :

• Extraction of smoke from a single compartment to the outside of the building
• Extraction of smoke from fire compartments of a building, using a smoke evacuation system and heat

In accordance with the EN 12101-8 product standard for smoke extraction dampers, all fire protection solutions must now meet specific criteria and be CE marked.

The new MSD-F smoke extraction damper has been tested and certified according to this standard and is intented for installation in areas with single-compartment applications. It is equipped with a thermal jacket and an AQ10 electric actuator. It meets the requirements of a CE marking.

New airtight circular sleeve MCE

The airtightness of ventilation systems has become a major building issue in recent yeas. In effect, the airtightness problem inevitably leads to loss of efficiency, overconsumption, poor energy performance and therefore additional costs and sometimes degraded indoor air quality.

F2A now respond to these leakage problems at the connection elements with its new airtight circular sleeve MCE.

With a leakage rate Class C certified according to EN 15727 (Leak divided by 9 compared to class A), the new MCE greatly reduces the energy consumptions compared to standard rolls of flexibles sleeves.

Efficiency and thermal comfort in a professional environment ?

The five reasons for moving to textile duct diffusion.

The very flexibility of the textile duct, its extensive options and the uniformity of its diffusion provide an effective response to the challenges of comfort, air quality and energy efficiency in service sector premises or those open to the public.

1- High-quality air diffusion

No stagnant air, control of residual air velocities and an appropriate mixing rate for optimum comfort of occupants (no draughts). Every project is analysed by our Design Office which will then propose the most efficient solution.

2- Quick to install

Diffusion solution with few restrictions due the lightweight materials used and their resistance. It is therefore simple and quick to fit and dismantle textile ducts. It is two to three times quicker to install textile ducts than metal ones.

3- Use of technical fabrics = safety and attractive appearance

The textile ducts manufactured by F2A meet the regulatory requirements in force with the use of technical fabrics with A2 or B Euroclass fire rating. All the textile ducts are available in several colours (more than 120 shades for polyester fabrics) to tie in perfectly with any architecture.

4- Huge flexibility – customised 100% manufacture

The textile duct can be used to create complex networks: connection sleeve, airtight collectors, tapping, elbows, conversion parts.

All geometric shapes can be produced in line with the restrictions of your site (limited space, beams, structural framework, etc.). It can be manufactured as a circular shape, half-circular, quarter-circular, oblong, etc.

The textile duct is a flexible solution as it operates effectively in several climatic modes: hot, cold, ventilation.

5- Simple to service

F2A textile ducts are very easy to service and are an ideal hygienic solution for food industry and clean room applications. No risk of condensation, the polyester fabrics can be washed in professional machines.

Frost issue in heat exchangers

The formation of frost in air-to-air heat exchangers is a persistent issue in locations with temperatures below -5°C. Condensation occurs when some of the transfer surfaces temperature drops below the dew point of the warm airstream, and this condensation turns to ice which causes the heat exchanger to consume energy. This happens as a result of the ice formation reducing the air section and increasing pressure loss, so there are more consumptions from fans.

Depending on the temperature of the air supply, humidity of exhaust air, and the efficiency of the heat exchanger the rate at which frost will accumulate will vary. In regions with persistent freezing temperatures or no fluctuation in temperature above freezing airflow can stop completely after frost or ice formation. Between countries, there are different ways of dealing with ice formation: shutting-off fresh air inlet or by-passing the heat exchanger. In one case the ventilation recycles stale air over and over (bad Indoor Air Quality) and in the other it stops recovering the heat from return air.

A classic issue in cold climate is to over-heat or shut down the ventilation function to prevent frosting, but this goes against performance and air quality requirements. However, F2A, a French leading company in ventilation and heat exchanging technology, is developing an innovation to solve this issue with their next generation of heat exchangers.

The patented solution will operate with integrated bypass, anti-frost functions, and alternate between different flow techniques to achieve unique performance.

To face the freezing issue while keeping the best efficiency, F2A’s next generation heat exchanger combines co-current and counter-flow principles in one single product. This innovative feature enables a high efficiency with counter-flow technology, and a proper functioning down to -20°C by switching to a co-current flow at low temperatures.

Co-Current functioning : Prevents freezing at low temperatures while recovering heat from return air.

This cold climate issue affects 2/3 of EU countries and all of the Northern and Eastern European countries along with North America and Russia. Existing heat recovery solutions are not able to deal with frost issue and negatively impact the efficiency of the overall building.

F2A’s breakthrough innovation will provide a real energy and cost saving solution.

EUROMÉDITERRANÉE : an urban regeneration project in Marseille city center

Launched by the French government and various local authorities (Ville de Marseille, PACA regional council etc.) in 1995. This huge 1,200-acre project is part of a global repositioning of the city’s image within the international landscape of dynamic cities.

One of its many architectural projects is the EUROMED CENTER, a 70,000 sq. metre complex of offices, shops, multi-screen cinema, 4-star hotel, park and car park. EUROMED CENTER will house the first office blocks with High Quality Environmental and BBC (low energy building) certification.

Our acoustics department carried out studies for the 846-space car park, the 210-room, 4-star “Golden Tulip” hotel and the 48,000 sq. metres of office space. We then proposed F2A solutions that met all the project’s different requirements.

Aeraulic requirements :

• For the car park the 24 ventilators required, which have an output of 7,200m3/h to 96,300m3/h, inevitably generate noise pollution. It was therefore recommended that an acoustics study be carried out to find solutions to reduce noise pollution. For this type of use, the splitters provided must also comply with smoke control requirements.

• The 4 office blocks are fitted with 7 air handling units (AHUs) with an output of 3,700m³/h to 14,000m³/h. The NF S31-080 standard sets out the acoustic requirements that must be met for this type of building – 30 to 62 dB(A) according to the type of office and the overall noise level required. Our acoustics experts also had to respect the NR35 noise rating of 40 dB(A) maximum.

• The hotel has 9 AHUs with outputs of up to 22,000m³/h, as well as a heat pump for its swimming pool and an extractor. The acoustic requirements set by the standard and acoustic instructions are NR25 limited to 30 dB(A). The fan coil units in the hotel bedrooms were dealt with specifically as certain objectives had to be met (installation of sound traps).

Selected solution :

We carried out pre-acceptance tests on every building and the acoustic design office in charge of the project carried out the final measurements which confirmed the efficiency of our solutions and the precision of our calculations.

The second highest tower in Marseille, the “Marseillaise” tower, designed by Jean Nouvel’s architecture agency, is also currently undergoing studies for the supply of splitters. The project is due to be delivered in mid 2018.
