Reducing environmental impact
- Raising the energy efficiency of our products - a safe and immediate way to reduce their environmental impact. You will find examples of Daikin’s award-winning, energy-efficient, heating and cooling products here [link to Awards paragraph].
- Taking measures to avoid refrigerant emissions, which only contribute to global warming if released into the atmosphere. The European F-gas regulation is very useful in achieving this goal, as it requires regular inspection of air conditioning and heat pump systems, as well as the certification of installers and service technicians.
- Conducting research into the use and potential applications of the next generation refrigerants such as R-32. Alternative refrigerants with a lower GWP GWP: the Global Warming Potential of 1kg of fluorinated greenhouse gas relative to 1kg of carbon dioxide over a period of 100 years. R-410A, R-134a and R-407C are fluorinated greenhouse gases with a GWP of respectively 1975, 1300 and 1652.5 (values used by the European F gas regulation). 2010 Chillventa: first display of R-32 air conditioner than today’s hydrofluorocarbon (HFC) refrigerants, need more research and testing before they can be considered as a practical alternative for general use.

Daikin fulfils Dutch retailer’s corporate social responsibility goals
As part of its CSR policy, a Dutch retailer wished to introduce integrated energy-efficient cooling and heating system in its shops – and contacted Daikin Netherlands for assistance. A pilot project within two of its shops was set up in late 2009, which involved the installation of a VRV® heat recovery system, including Biddle air curtains. This was compared with a conventional system with separate air conditioning units for heating and cooling, as well as fossil fuel fired air curtains.
The first measured results looked impressive: net savings of 75% for both shops on an
annual basis1 and a reduction in CO2 emissions of more than 70%2, compared with the
1 Monitoring during the first quarter of 2010 supports the projected money savings of 75%

Rivergate office centre, Vienna, Austria
Daikin is proud to have contributed to the RIVERGATE project obtaining LEED (Leadership in Energy and Environmental Design) Gold status in the pre-certification process.
This new 50,000-m² office centre, is located in one of Vienna’s most attractive locations: the Danube waterfront north of the city centre, close to Danube Island. The office centre comprises two gates, the first gate being 12 storeys high, the second gate having eight storeys.
Daikin Airconditioning Central Europe HandelsgmbH delivered over 3 MW of high efficiency water-cooled chillers for this project. For cooling, Daikin suggested two high efficiency water-cooled chillers. Both water circuits operate in series with low delta T and high efficiency
variable flow pumps, further increasing the system’s efficiency and control possibilities.
For heating, two high efficiency water-source heat pumps extract heat from two sources: the building foundations (geothermal) and Danube river water (hydrothermal).
