Imagine a sustainable future for commercial buildings

The answer lies in retrofitting – that is, improving building’s energy generation and supply and/or the way energy flows within the building. Making even small adjustments can go a long way in decarbonizing commercial buildings and mproving how energy flows throughout the building is the area that holds the most promise in terms of energy efficiency gains.

Benefits

Retrofitting increases energy efficiency and reduces carbon emissions

Renovate smarter to cut costs and boost your building’s performance. Over 30% of the EU’s energy-related greenhouse gas (GHG) emissions come from buildings and 80% of the energy supplied to buildings is still derived from fossil fuel sources. An effective retrofitting strategy looks at how your building can utilize renewable energy sources, such as district heating. It includes installing heat pumps and chillers that can recycle and reuse excess heat, thus lowering your building’s energy consumption, increasing its efficiency and turning it into an energy supplier as well as an energy consumer.

Retrofitting helps you comply with national and international regulations

Retrofitting will help with the Energy Performance of Buildings Directive (EPBD), the Science Based Targets Initiative or energy performance certifications. It involves optimizing the way energy flows in your building and using digital technology to make your buildings smarter, so you can forecast and anticipate changes in energy demand and identify ways to boost efficiency. These measures reduce your building’s carbon footprint and put you on the path to achieving your climate goals.

Retrofitting improves property values and gives a solid return on investment

Optimizing building’s HVAC system can reduce energy usage by an average of 22% per building, with a payback time of 2 years. The technologies necessary to implement a successful retrofitting strategy are already available, and most offer a payback time of under 5 years. And with carbon pricing on the horizon in many countries, boosting building’s energy efficiency makes good financial sense. ESG reporting requirements are driving companies to think holistically, decarbonizing their entire operations and supply chain. Offering commercial retail space in buildings that are as energy efficient as possible will ensure properties are more attractive to companies with a sustainability focus.

Webinars

Energy retrofit – Why, how and what

To meet climate targets, we must renovate buildings to improve energy efficiency. This webinar shows how to optimize primary energy use, reuse wasted energy, and optimize energy distribution in commercial and residential buildings.

Improve sustainability performance

Over 80% of all existing heating systems have an immense optimization potential. Retrofitting is an ideal way to unlock this potential and enhance your commercial building’s performance and sustainability.

Retrofit in Commercial buildings

The building sector is the EU’s largest energy consumer, using 42% of all primary energy and accounting for 36% of GHG emissions. 80% of
building energy still comes from fossil fuels. Decarbonizing buildings is crucial.

How EPBD and Danfoss solutions drive energy efficiency

Buildings are central to our lives, with people spending 85-90% of their time indoors. Renovating buildings not only improves quality of life but also saves money, combats climate change, and reduces energy price hikes. Building Automation and Control Systems (BACS) are essential for optimizing energy use. Learn how BACS can be considered the "brain" of your building, significantly increasing efficiency and enabling smart interactions with advanced energy systems.

Retrofitting Commercial buildings with modulating Room Control

Retrofitting with advanced Building Automation and Control Systems (BACS) is one of the most effective ways to optimize energy use, reduce costs, and enhance indoor comfort. Discover how upgrading from on/off room control to modulating control can significantly improve energy efficiency in commercial buildings.

How Digital Hydronics can transform HVAC systems into HVAC 4.0

Retrofitting commercial buildings with Danfoss Digital Hydronics enhances system efficiency and performance. It offers seamless integration of hydronic balancing with precise temperature control, utilizing pressure-independent control valves and digital actuators. By incorporating Building Automation and Control Systems (BACS), this advanced connectivity transforms traditional HVAC systems into HVAC 4.0 through data-driven control. NovoCon® digital actuators play a key role in optimizing system operations.

Case stories

Delft University of Technology partners with Danfoss to create a sustainable heating system

Delft University of Technology (TU Delft) aims to achieve a carbon neutral, circular and climate adaptive campus by 2030. One of the keys to realizing this ambitious goal is the university’s geothermal project, which will provide sustainable heating to both the campus and approximately 6,000 households in Delft.

Why hot water is key for happy hotel guests

Hotels across Southeast Europe are scaling down their use of burner oil as a heat source for their Domestic Hot Water (DHW) boilers, instead adopting renewable alternatives such as heat pumps or district heating.

A win-win project

At any hotel, guest satisfaction is a top priority, and ensuring that rooms are a comfortable temperature is key to keeping customers
happy.

New EU legislation

The EU's revised Energy Performance of Buildings Directive (EPBD) mandates hydronic balancing in new and renovated buildings to improve energy efficiency and comfort. This means new heating/cooling systems must be balanced from the start, and existing systems must be balanced when the heat or cooling generator is replaced. The legislation also requires buildings over a certain size to have Building Automation and Control Systems (BACS) to optimize performance, which is increasingly relevant for dynamic hydronic balancing solutions.
