REHVA Task Forces
The
objective of REHVA Technology and Research Committee is to develop and
disseminate technical information for the benefit of REHVA members and
supporters, enhance development of standards and research on European level,
and increase the REHVA participation and visibility at European level
activities.
To achieve
these objectives, REHVA has established Task Forces, each with a specific
topic. Each Task Force will prepare a REHVA publication, and REHVA Guidebooks
are the main outcome of Task Forces. In some cases, a Technical Report is a
more suitable outcome, especially in rapidly changing or developing issues.
The
tradition of REHVA Task Forces and Guidebooks is rather young. The idea of
Guidebooks matured at the end of last Millennium, after several discussions
about the needs of practical and reliable documentation of European good HVAC
practices, targeted directly to designers and other HVAC practitioners and also
to other stakeholders. Finally, in spring 2000, the first action towards a
REHVA Guidebook started, with the topic of Displacement
Ventilation.
This topic had been dealt with in numerous research reports, articles in
professional journals, commercial brochures etc., but the information there was
either fragmented, unpractical or commercially biased.
The format
of Guidebooks, and also working practices of Task Forces, developed during the
first project and still are much the same: first make a clear working plan and
establish a working team, prepare a manuscript within a realistic schedule, and
also make sure that the publication will sell.
In late
2002 the first Guidebook was published, and it still is one of the bestsellers.
The principles of displacement ventilation are still the same, but technologies
have developed and new applications have been commercialized, so the Guidebook
No. 1 will be subject to revision which is currently about to start.
Since year
2002, teams of experts from all parts of Europe have participated in the work
of Task Forces, often on a voluntary basis. A typical team consists of 4-6
experts, but in a few guidebooks or reports the number of contributors has been
up to 20 or even more. All manuscripts are reviewed independently by well
recognized experts.
The number
of printed Guidebooks reached 20 in June 2013, when three new books were
published and on display at Clima 2013 in Prague. At
the same time, a Technical Report containing a proposed all-European framework
definition of nearly zero energy building was published, this is TR 4 but
actually the first one resulted from an “ordinary” Task Force – the first three
were the collections of Workshop summaries from Clima
conferences in 2005, 2007 and 2010. The decision to make a Technical Report was
relatively easy: the need to disseminate the TF results was urgent, but the
outcome is subject to change very soon, due to many changes “around”.
The most
successful Guidebooks have one common feature: strong “push” and commitment
from the industry.
The working
language in the Task Forces is English, as well the official original version
of the Guidebook. But as a European organization over 20 languages are spoken
within REHVA member associations. To reach better the national professionals
the Guidebooks can be translated to national languages. REHVA offers this
opportunity as a membership benefit to its members. More than 50 translations
(see table below) are available through REHVA National members (contact
information at www.rehva.eu).

Active REHVA Task Forces
(TF) August 2013
Name of the Task Force, Schedule
and Chair/contact person | Descriptive
objective of the Task Force |
Air Conditioning inspections -
Technical Guideline 2012-2015 Chair: VincencButala University of Ljubljana Slovenia vincenc.butala@fs.uni-lj.si | This TF
aims to prepare a technical guideline for inspections of air conditioning
systems, to support the implementation of Article 15 of the EPBD recast. |
Reference Buildings for Energy
Performance and Cost-Optimal Analysis 2012-2014 Chair: Stefano
P. Corgnati, Politecnico di Torino Italy stefano.corgnati@polito.it | This TF
aims to develop, on the bases of the national experiences, a set of European
Reference Buildings/benchmark buildings in order to suggest European wide
harmonized database of building types which could be used for cost optimal
calculations according to EPBD recast at European level by technicians and
researchers. So far ongoing activities on the definition of national approved
RBs are being developed and they are still far from
being closed. Due to this fact, TF is now focusing in conducting cost optimal
analyses and comparing the results of these between different MS in order to
give some useful information to policy makers and investors. |
Environmental-friendly Refrigerants
in HVAC Applications 2012-2014 Chair: Attila Zoltán Hungarian Coordination Association of
Building Engineering attila.zoltan@t-online.hu | This TF
aims to prepare a Refrigerant Guidebook which will help to define the optimal
system-equipment-refrigerant couple for dedicated applications. The guidebook
will introduce how to reduce, optimise the cooling
power needed, the environmental impacts and energy efficiency of the
equipment, including global parameters of refrigerants (ODP, GWP), energy
efficiency (EER, ESEER, COP, SCOP), direct-indirect environmental impacts of
equipment, systems, the TEWI (CO2eq) and TEEI (inversed TEWI, kWheq) comparison methods. |
HVAC systems long term impact in
buildings valuation 2013-2015 Chair: Frank Hovorka Caisse des Depots France frank.hovorka@caissedesdepots.fr | HVAC
related building performance is often insignificant in the context of an
overall building evaluation made by potential investors. The TF thus aims at
bridging the gap between HVAC engineers and building investors by translating
typical HVAC system benefits into tangible financial benefits for the overall
valuation of real estate. “Global costs” considering functionalities,
investments costs and operation & maintenance issues are taken into
account and the methodologies for translating the HVAC benefits to
real-estate valuation will be presented and demonstrated with real life
examples. |
Energy refurbishment, 2013-2015 Chair: Marija S. Todorovic Academy of
Engineering Sciences of Serbia deresmt@eunet.rs | EnRef
TF aim is to prepare guidebook/s on the topic of the energy refurbishment
encompassing holistic approach to the deep energy renovation of existing
buildings, to the level of energy efficiency and renewable energy sources
(RES) integration that ensures clear “zero” or “net zero” energy quality of
the refurbished buildings status. TF promotes large-scale RES integrated
buildings structure/HVAC refurbishment technologies development, as well as
necessary R&D to commercialize “RES Integrated Energy Refurbishment Construction/HVAC - Industry” as
a whole integrated engineering process. |
nZEB Nearly Zero Energy Buildings 2012-2015 Chair: JarekKurnitski Tallinn
University of Technology, jarek.kurnitski@ttu.ee | nZEB TF
revised REHVA nZEB technical definition during
2012-2013, with the aim to help the experts in the Member States to define
the nearly zero energy buildings in a uniform way. The revision, coordinated
with CEN project group preparing 2nd generation EPBD standards, was published
in June 2013 (REHVA REPORT NO 4, 2013). The work will continue as a new task
force focusing on nZEB case studies/technology with
on site and nearby production and trying to find assessment method/indicator
for “real addition” of RE energy and optimal performance on energy system
level. |
Combined Heat and Power (CHP) for
buildings 2012-2015 Chair:
Klaus Sommer Cologne University of Applied Sciences Germany klaus.sommer@fh-koeln.de | In order to achieve the EU targets on energy savings and on reduction of greenhouse gas emissions the decentralized cogeneration (CHP) on individual building level can play an important role. This TF will produce a REHVA guidebook that covers different technologies of small and middle size CHP for different applications. Key aspects are system engineering and control, system operation and economic feasibility that will be derived from field tests and practical applications. |
Fire safety in buildings: Smoke
management guidelines, 2012-2014 Chair: OthmarBraendli Belimo Switzerland othmar.braendli@belimo.ch | This TF aims to prepare state of the art guidebook on fire & smoke solutions. It will provide approved fire & smoke solutions and show latest status of European fire & smoke standards and regulations. |
Heat pump applications in
refurbishment 2012-2014 Chair: BranimirPavkovic Croatia branimir.pavkovic@riteh.hr | This TF
will produce a new guidebook on heat pump applications for new buildings and
for refurbishment. Heat pumps can in some cases efficiently be implemented in
existing systems of heating and cooling, providing cost effective solution in
refurbishment. Limits of such application and proper system design will be
discussed. General information suitable for target groups will be provided. |
Cold climate design guide (ASHRAE/REHVA), 2012-2015 Chair: BjarneOlesen, Technical
University of Denmark bwo@byg.dtu.dk | This TF
aims to prepare a cold climate design guidebook in cooperation with ASHRAE. |
Weather Data Directory 2012-2014 Chair: LivioMazzarella, Italy Livio.mazzarella@polimi.it | The aim
of this task force is to develop, on the bases of the worldwide available
information, a weather data directory for HVAC design and performance
simulation, which collects in a simple and concise way all references to
national and/or regional weather data, their availability, statistical
validity and application purposes. |
Commissioning process Reactivation
of the old TF, contact person: Ole Teisen,
Ole.Teisen@grontmij.dk | In spite
of the many standards there are different approaches to the commissioning
process, and a lot of work is done in the name of Commissioning that is not
adding any value to the buildings. We need more stringent requirements for
verification of buildings and systems in order to verify planned energy
savings and achieve sustainability certification. To achieve these aims, this
TF will prepare guidelines
and guidance on the Commissioning process. Besides supporting the
Commissioning requirements of various sustainability certification programmes, the guidebook shall serve as a tool when
doing a commissioning process on refurbishments. |
Indoor environment in the
implementation of policies and technologies for energy efficient buildings New
proposal by FINVAC | There is
a need a position paper on indoor environmental issues aimed at policy makers
and authorities to point out the potential conflict between energy efficiency
and indoor environment and to develop protocols and criteria for design and
construction and operation practice. |
Displacement ventilation New
proposal by TRC | Existing
displacement ventilation guidebook is sold out and already so old that needs
to be updated. TRC will initiate new TF with the aim to revise and publish
new displacement ventilation guidebook. |
