Energy efficiency improvements in renovations<\/h2>\n

Summary:<\/strong>
\nEnergy 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 \u2013 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 fa\u00e7ade and plumbing renovations. The goal is to ensure that energy improvements are cost-effective and support the long-term functionality of the building.<\/em><\/p>\n

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.<\/p>\n

Selection of energy efficiency improvements for renovations<\/h2>\n

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.<\/p>\n
