Dalkia Key Words

Energy efficiency encompasses all methods and techniques that reduce energy consumption. It lowers energy costs, controls consumption and provides more efficient production tools. Energy efficiency is a leading focus of French and European ambitions to curb greenhouse gas emissions, since the European Union has set a target of improving energy efficiency by 20% by 2020.
Energy efficiency is a core Dalkia focus and a challenge that concerns all economic stakeholders, including industrial operators and the housing sector, to name two. Dalkia provides cost-effective, eco-friendly energy efficiency services that include performance guarantees for our public- and private-sector customers around the world. We have devised complex analytical methods to identify priority areas for optimization.

Renewable energies are a Dalkia priority. Their development makes it possible to replace fossil fuels with "green energies," improving the energy and environmental efficiency of installations.
The International Energy Agency (IEA), like the European Union and Grenelle Environment Forum in France, has made the development of renewable energies a top collective priority, setting growth targets of 20% by 2020. Dalkia is introducing a growing amount of renewable energies—especially biomass but also geothermal energy, landfill gas and solar energy—at all of the facilities we operate.

Cogeneration is an especially efficient environmental solution. Indeed, CHP technology can simultaneously produce heat and power from the same facility. This results in energy savings of 10 to 15%, while also reducing consumption and greenhouse gas emissions.
Cogeneration is equally suited to producing heat for community networks and industrial energy production systems. Supported by European legislation and encouraged by the International Energy Agency, it is promoted by a system of incentives in France. Dalkia manages more than 1,200 cogeneration facilities worldwide.

District heating networks are community installations that use a single facility to produce and distribute the heat needed for indoor heating and domestic hot water for several buildings or housing units.
They usually consist of thermal energy production and distribution facilities operated under a public service delegation contract. Heating networks replace individual installations, which are often polluting and undependable, with a single community facility managed by an expert capable of operating and optimizing it. Governments and local authorities support the development of district heating networks, which also sharply lower greenhouse gas emissions by facilitating the introduction of a large volume of renewable energies, such as biomass, heat recovery from incineration and geothermal energy.

Dalkia operates 887 district and local networks worldwide that produce heat, hot water and cool air, managing 5.8 million multifamily housing units and 119,600 energy facilities.

Biomass is the most abundant renewable energy available in France.
It consists mainly of wood not recycled by the forest industry, that is, the portion not usable as lumber, and industry by-products such as branches, damaged, unusable wood and prunings.
Recycled wood and energy crops are another source.
A fossil fuel replacement, biomass sharply curtails carbon emissions and shelters users from the economic havoc of fluctuating oil and gas prices. Its carbon-neutral footprint and wide availability in various forms add to the virtues of this energy, which is strongly promoted by governments.

Dalkia is massively expanding the use of biomass, especially in heating networks and at industrial cogeneration facilities.
In 2010 Dalkia consumed 2.4 million metric tons of biomass worldwide. In France alone, Dalkia could be recycling four million metric tons by 2015.

Geothermal is a renewable energy produced from "the earth's heat." It primarily takes the form of steam and hot water reservoirs. Their heat can be recovered, in particular to meet heating needs. Water from deep underground is pumped up and transmits its heat to a network, to provide some or all of the thermal energy needed by a community. Although renewable geothermal energy is ripe with possibilities, it is unfortunately unequally distributed.
However, some regions, such as Ile de France (Greater Paris), lend themselves especially well to its development. Dalkia is a major geothermal specialist and operates 17　wells that supply more than 80,000 housing units in the Paris region.

Comprehensive building management includes any service that improves the energy and environmental performances of a building while optimizing its operation. Examples include reducing consumption and energy or heat losses and optimizing the operation of installations. Multi-technical CBM services apply to equipment that produces power, heat and cool air, electrical installations and a wide array of related services.
The latter include waste management, maintenance, record management, reception and security services. By hiring Dalkia to provide all these services, bundled into one package, our clients know that they can count on our complementary areas of expertise and quality of service.
This allows them to focus on their own core business.

We gained our experience with comprehensive building management all over the world, working with different local authority, business, healthcare facility and retail customers.

The environmental efficiency of a system or facility boils down to reducing its environmental impacts. Everything Dalkia does furthers that purpose, which is illustrated first and foremost by the reduction of the greenhouse gas emissions and carbon responsible for climate change.
We improve the energy and environmental efficiency of the installations we operate through effective, innovative solutions and the deployment of more appropriate, greener technologies.
Cogeneration, the introduction of renewable energies such as biomass, the use of alternative fuels, optimized facility operation and the development of community infrastructure are all services that strongly contribute to environmental protection.

In 2010, Dalkia saved 7.1 million metric tons of carbon emissions at installations we operate around the world.
