Energy efficiency improvements in renovations
Energy efficiency improvements in renovations
Summary:
Energy efficiency as part of the renovation. Energy efficiency improvements implemented in connection with a renovation can reduce a building’s energy consumption, operating costs and environmental impact. Sweco offers expert support for the entire process – from the assessment of alternatives to implementation and monitoring. The services include, among other things, improvements to heat distribution centres and ventilation, automation solutions, electrical and cooling renovations, as well as façade and plumbing renovations. The goal is to ensure that energy improvements are cost-effective and support the long-term functionality of the building.
With the help of energy efficiency investments made in connection with the renovation, significant improvements in the energy efficiency of the building can be achieved. At best, in addition to reduced operating costs, the environmental load is also reduced without compromising living comfort. Sweco offers all expert services for energy efficiency improvement options to be considered in connection with renovations, from support for decision-making to implementation supervision and follow-up.
Selection of energy efficiency improvements for renovations
The key challenges are related to identifying and comparing the right measures and assessing their impacts. It is important to identify all relevant energy improvement opportunities and compare their impact on energy efficiency, costs, E-value, environmental conditions and potential financing. In addition, energy improvements can affect, for example, the dimensioning of the heat distribution centre or heat pumps, so their effects must be accurately simulated and assessed.
Renovation | Our design services for energy improvements
Renewal and improvement of the heat distribution centre
• Redimensioning of the heat distribution centre
• Improvement of heat distribution: sensors, pumps, radiator thermostats, smart control
• Introduction of heat pump solutions
• Hybrid solutions, such as exhaust air heat recovery or geothermal heat
Facade renovation
• Increasing thermal insulation and improving tightness
• Passive design that takes into account: energy efficiency of windows, balcony solutions, external shading
• Synergy opportunities, such as the purchase of solar panels

Sweco helps to identify and assess the most suitable energy improvements that can be sensibly combined with the renovation of the site. With the help of Sweco’s professionals, you can ensure that the investments made in connection with renovations produce significant benefits in accordance with the set goals. This approach not only improves the energy efficiency of the building, but also potentially minimizes additional costs and ensures that the building functions optimally right from the start.
Sweco’s solutions for defining energy improvements
- Site visit and preparation of a calculation model
- Building technology functionality review and calculation of energy improvements based on real energy needs
- Simulation of measures and comparison of the effects of alternative combinations of measures on energy consumption and investment and maintenance costs
- Selection of measures to be compared
- Decision-making based on information where possible
With Sweco, you can get answers to questions such as:
How should automation be improved?
What will be done to the structures during the renovation?
How does the renovation affect heat distribution?
How do different renovation measures affect lifecycle costs, figures, certificates and conditions?
Is it worth replacing the windows or improving the ventilation?
