517milliontons of CO2 could be saved per year

if Europe doubled its use of district heating to 18-20% and combined this with increased reliance on renewable energy sources.

40%energy is typically saved

when fans and pumps in commer-cial buildings are controlled with variable speed drives from Danfoss. Pay-back time is usually 1-2 years.

MAKING MODERN LIVING POSSIBLE

330,000 Americans use the same amount of energy

and CO2 in their homes as that saved by Danfoss Turbocor compressors installed in commercial buildings worldwide. Far less than 1% of these buildings are covered today.

Energy efficiency saves money and CO2 today

The world is facing major climate challenges combined with fast-growing energy consumption, scarceness of resources and increasing energy prices. Danfoss solutions within climate and energy efficiency can help address these challenges right away.

Global energy demand is predicted to increase by over a third in the period up to 2035, but immediate action is possible by focusing on energy efficiency and the well-proven technologies that save energy and money, here and now. This is the fastest and cheapest way to move forward and holds enormous potential that will boost our economy in the short term and in the longer term will allow us to afford renewable energy sources.

With energy efficiency, we have the best basis for addressing the climate and energy challenges and for making modern living possible in the years to come.

Making modern living possible through climate and energy solutions

Picking thelow-hanging fruits

Oil-free compressors:

Saving the energy and CO2 used by 330,000 Americans in their homesDanfoss’ Turbocor compressor is the first oil-free, variable speed compressor that provides high energy-savings for indoor heating, ventilation and air conditioning systems (HVAC). The pay-back time typically varies from 1 to 3 years depending on the application.

Today, 1.5 million tons of CO2 are saved every year through the Turbocor compressors installed in commercial buildings worldwide – a figure that is equivalent to the amount of energy and CO2 used by 330,000 Americans in their single-family homes annually. However, far less than 1% of commercial buildings have systems installed with this kind of compressor today. Some 950 million tons of CO2 could be saved per year if all buildings of this type in the US alone had indoor climate systems with oil-free variable speed compressors. This is equivalent to the energy and CO2 used by 213 million Americans in their single-family homes each year.

In action: A large building in Hollywood called the NoHo III Office has been awarded the highest possible energy-efficiency rating with the help of Danfoss Turbocor compressors. The compressors were 24-28% more efficient than any other positive displacement compressor that the customer evaluated.

Electronic motor control:

Saving the CO2 emissions of19 million carsVariable speed drives control the power supply to electric motors in, for example, heating, ventilation and air conditioning systems in buildings as well as to motors in industrial cranes and conveyor belts, and public water supply systems. This ensures that the motors run at precisely the speed necessary to obtain the desired effect and typically saves 15-40% energy depending on the application.

Today, 4 million variable speed drives from Danfoss are installed worldwide and together they save as much as 37 million tons of CO2 every year – a figure that corresponds to the CO2 emissions from more than 19 million cars in Europe. However, 70-80% of new industrial electric motors are wasting energy because they have not been fitted with variable speed drives to control their energy use. The number is even higher for the electric motors already installed.

In action: Installation of energy-efficient variable speed drives on 28 fans in Belfast International Airport in Ireland has led to annual savings of 112,000 Euros per year and a reduction of 500 tons of CO2 emissions.

District energy:

Saving a year’s electricity production by all the world’s windmillsDistrict energy is an infrastructure that distributes heating and cooling to buildings in cities. It can utilize all kinds of energy sources – including renewable sources. It can even capture and utilize surplus heat from power generation, referred to as combined heat and power. Today, more than 60% of the energy produced in power plants is actually wasted. This can easily be avoided through combined heat and power. However, only 8% of the current electricity capacity globally comes from this source. An increase to just 14% would generate energy savings equivalent to a year’s electricity production by all the world’s windmills.

Danfoss provides complete systems for heat transfer and the utilization of hot water in buildings such as substations; and key components like heat exchangers and controls. These systems and components typically enable savings of 20-30% energy both in district energy networks and for end-consumers in buildings.

In action: Beijing Heating Power Group has obtained energy savings of 37% in its Niujie apartment blocks in Beijing city center with help from a Danfoss district heating solution. At the same time, the occupants maintain an indoor temperature of 18°C and save approximately 13% of their heating costs.

Electronic thermostats:

Cutting energy consumption by 16-23% Electronic radiator thermostats help residents control room temperature in their houses in a systematic way. Studies have showed that a private home can save at least between 16-23% on energy consumption if all manual radiator thermostats more than 15 years old are replaced with new electronic living by

Danfoss thermostats. Pay-back time is less than 3 years depending on the energy source in the building, and the investment for an average household is as low as 500-600 Euros.

Today, less than 2% of all Western European households use electronic thermostats. Some 11 million tons of CO2 would be saved if these households had their old manual thermostats replaced by new electronic ones. This corresponds to the CO2 emissions from more than 5.8 million cars in Europe per year. The spread of electronic thermostats is even lower in other parts of the world so the potential globally is huge.

In action: A family in Solbjerg, Denmark, had their old thermostats replaced with electronic thermostats from Danfoss. After six months the results were better than expected: energy consumption was reduced by 28%. In addition, the indoor climate has been improved and the family no longer has to contend with changing the temperature and constantly adjusting their radiators.

Cooling of food:

Cutting energy consumption by 20% Efficient control of refrigeration in grocery stores ensures that energyconsumption is automatically matched to actual need and not wasted.Danfoss’ control system ADAP-KOOL® typically helps stores achieve around20% savings in energy. Pay-back time is only 1-2 years.

As much as 6 million tons of CO2 are saved every year through energy-efficient control of refrigeration in 280,000 grocery stores globally. However, less than half of modern grocery stores are doing this today. Some 16 million tons of CO2 could be saved every year if all modern grocery stores globally optimized their refrigeration energy-efficiently. This corresponds to the CO2 emissions from more than 8 million cars in Europe.

In action: Installation of Danfoss’ ADAP-KOOL® system in 55 stores run by the Tûs supermarket chain in Slovenia has reduced energy consumption by an average of 17% and has resulted in savings of 212,000 Euros per year.

Natural refrigerants:

Cutting the equivalent amount of CO2 that Peru emits annually A 60% reduction in CO2 equivalent emissions can be achieved in food retailers’refrigeration systems by replacing synthetic refrigerants with natural CO2.Synthetic refrigerants like HCFC’s and HFC’s have a global warming potentialthat is 2,000 to 4,000 times that of CO2 and due to system leakage they escapeinto the atmosphere.

Less than 1% of grocery stores globally use natural refrigerants today. At least50 million tons of equivalent CO2 could be avoided annually if grocerystores globally switched from synthetic to natural refrigerants such as CO2.This corresponds to the annual CO2 emissions of Peru or Norway.

Danfoss is a market leader within solutions that make it possible to makethe switch from synthetic refrigerants to CO2.

In action: UK retailer Sainsbury’s has converted the refrigeration system in more than 100 stores to CO2 and thereby saved 250,000 tons of CO2 since conversion began in 2010. Sainsbury’s aim is to replace F-gases in every one of their 800 stores, cutting their total carbon footprint by a third. The CO2 systems are supported by Danfoss products and services.
