Use

Our environmental initiatives are not limited to the manufacturing process and supply of world-class HVAC solutions. Daikin Europe N.V. demonstrates the same vigorous environmental leadership in our determination to reduce the environmental impact of energy consumption and potential refrigerant emissions once our products are actually in use. 

Reducing environmental impact

What Daikin is doing to reduce global warming impact during product use:

  1. 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]. 
  2. 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. 
  3. 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.

Prestigious projects

CO2 neutral Park Phi chooses Daikin

The CO2-neutral Park Phi project, now under construction in Enschede, Netherlands, is a business centre comprising three office blocks. On each floor, Daikin VRV units with heat recovery and Daikin chillers are networked so that each floor can maintain exactly the right comfort settings, while operating in the most efficient way. 

Features include heat exchange between the cold and warm parts of the building, and a ventilation system that automatically adapts to the CO2 levels in the building. Energy that can’t be used immediately elsewhere in the building is stored in a purpose-built 25-km aquifer. All of this adds up to an impressive energy performance making it the most sustainable business centre in the Netherlands. 

Eurospar saves energy and money with Daikin Conveni-Pack

Optimum energy efficiency and financial payback was sought when designing the new Eurospar supermarket in Huldenberg, Belgium, which opened in June 2009. Cooling, heating and refrigeration represents a significant share of the energy demand, while space and noise limitations were also significant to the system design.

To meet these requirements, Daikin’s Conveni-Pack was selected for its high energy efficiency. Conveni-Pack’s integrated approach to cooling, heating and refrigeration results in drastically reduced energy consumption and CO2 emissions, because free heat extracted in the process of cooling the refrigerators and freezers is used to heat the shop in the winter. 

Each unit is equipped with a heat pump for creating extra heat, should heating demand  exceed the supply of recuperated heat. This heat pump eliminates the need for an additional heating installation. A computerised central control unit ensures optimum service to the various zones in the building: shop area, storeroom, refrigerators and freezers. 

As a result of the energy savings achieved, Conveni-Pack provided payback within three years for the additional investment compared with a traditional system.

Perseo and Auros management centres, Milan, Italy

The Italian Galotti real estate group chose Daikin Italy to provide support in designing climate control systems for its new Milan-based Perseo and Auros class A4 buildings.

Both buildings were designed and built to minimise environmental impact, by reducing winter heating and summer energy losses, rationalising energy use and incorporating renewable energy sources.

The installed solutions included Daikin VRV® heat recovery systems, which deliver 5.9 kWh/m³ per year for heating. This represents a saving of 50.9% 5 in total operating costs and drastically reduced CO2 emissions (less than 4.2 kg/m3 per year).

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
conventional set-up.

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).
