New ASHRAE headquarters<br />
equipped with<br />
VRF air conditioning<br />
and heat pump<br />
The American Society of <strong>Heat</strong>ing, Refrigerating<br />
and Air-Conditioning Engineers (ASHRAE,<br />
50,000 members worldwide) started the modernization<br />
of its approx. 30-years-old headquarters<br />
of 3,000 m² in Atlanta (USA) a few<br />
weeks ago. As ASHRAE with its many partners<br />
around the world is very strongly committed<br />
to energy efficiency and good interior quality<br />
in buildings, one thing about the 5.4 million<br />
USD project was clear right from the start: In<br />
terms of energy efficiency and comfort, the<br />
technical building systems must meet the most<br />
modern standards, so that the “new” ASHRAE<br />
headquarters opening in June 2008 is awarded<br />
the “Gold Rating” based on the certification<br />
standards of the LEED system of the US Green<br />
Building Council (www.usgbc.com). The team<br />
of experts employed by ASHRAE developed<br />
the following solutions for this: The ground<br />
floor is air conditioned by an air-cooled, inverter-controlled<br />
R410A VRF air conditioning<br />
system with heat pump circuit, which can be<br />
controlled separately for individual areas of<br />
the building. A ground source direct expansion<br />
heat pump has been installed to supply the<br />
top floor and this can be switched from heating<br />
to cooling operation to suit the demand.<br />
Both heating/cooling systems are coupled to<br />
an air conditioning system that is driven by a<br />
100 % outside air unit and is used in the<br />
regenerators for exhaust heat recovery.<br />
To keep the costs of modernization as low as<br />
possible for the society, ASHRAE is making<br />
efforts to find sponsors and has even created<br />
a brochure for this purpose (www.ashrae.<br />
org/building). This states that the benefactor<br />
of donations of over 50,000 USD for products<br />
or services will be rewarded with a badge<br />
of honour in the foyer of the building. ✦<br />

Research Council for<br />
Refrigeration Technology<br />
celebrated on the<br />
stock exchange<br />
The Research Council for Refrigeration<br />
Technology celebrated its 50th birthday on<br />
20 September with a reception in the German<br />
stock exchange in Frankfurt. The Research<br />
Council has always been dedicated to<br />
promoting scientific research in the field of<br />
refrigeration generation and application in<br />
building air conditioning, commerce, industry,<br />
transport, heat pumps, domestic appliances<br />
and cryogenics and to initiating and conducting<br />
joint industrial research. The first Chairman<br />
of the Research Council in 1959 was<br />
Prof. Rudolf Plank, who was followed by<br />
Prof. Kurt Nesselmann, Dr. Emil Schmidt, Prof.<br />
Helmut Lotz, Eckart Prandner and Ewald<br />
Preissegger (2002 to present). The Research<br />
Council, which is based at the VDMA in<br />
Frankfurt, currently has 26 members from<br />
industry, research and training. The council<br />
has been managed by Director Dr. Karin Jahn<br />
since 1992.<br />
The Research Council for Refrigeration Technology<br />
is a partner of Chillventa and is also<br />
represented by Dr. Karin Jahn on the exhibition<br />
committee.✦ www.fkt.com<br />
