Fönster- reparera, renovera, komplettera
Fönster till avfall

Fönster är resurskrävande att nytillverka men ofta svåra att återbruka. Projektet tar fram ett praktiskt beslutsstöd som kombinerar inventering, laboratorieprovning och livscykelanalys för att avgöra när fönster kan renoveras, återbrukas eller bör bytas ur ett resurs- och klimatperspektiv.

Slutseminarium

Den 17 juni höll vi i ett seminarium där vi presenterade projektet och dess slutsatser. Här kan du se seminariet i efterhand:

>> Slutseminarium: När är det bäst att renovera, återbruka eller byta fönster? (Youtube)

Syfte och mål

Projektets syfte är att ta fram ett praktiskt och tillförlitligt beslutsstöd för renovering, återbruk eller utbyte av befintliga fönster. Målet är att ge fastighetsägare, konsulter och entreprenörer bättre underlag för att fatta resurseffektiva och klimatmedvetna beslut genom strukturerad inventering, kvalitetsbedömning och livscykelanalys (LCA).

Utmaning

Fönster är resurs- och energikrävande att nytillverka, samtidigt som de är komplexa att återbruka eftersom de måste uppfylla höga krav på bland annat energiprestanda, täthet, säkerhet och inomhusmiljö. Idag saknas standardiserade metoder för att bedöma kvarvarande teknisk livslängd och faktisk prestanda, vilket gör att fungerande fönster ofta byts ut i onödan. Detta leder till ökad klimatpåverkan, mer avfall och förlorade resurser.

Lösning

Projektet adresserar frågan: När är det bäst att renovera, återbruka eller byta fönster? Lösningen är en metodik som kombinerar systematisk inventering, laboratorieprovning och livscykelanalys. Genom att verifiera inventeringsresultat mot labbprovningar skapas ett robust underlag som samlas i en vägledande guide med praktiska verktyg. Metodiken kan användas i såväl underhålls- och ombyggnadsprojekt som i nyproduktion där återbrukade byggprodukter efterfrågas.

Effekt

Projektet förväntas leda till minskad klimatpåverkan, lägre resursförbrukning och ökat återbruk av fönster i byggsektorn. För fastighetsägare innebär det minskad osäkerhet, bättre beslutsunderlag och potential till kostnadsbesparingar. Samhällsnyttan kopplas till de globala hållbarhetsmålen, särskilt mål 11 (Hållbara städer och samhällen), mål 12 (Hållbar konsumtion och produktion) och mål 13 (Bekämpa klimatförändringarna), genom ett mer cirkulärt och kunskapsbaserat byggande.

GREEN-SAW: Tools for Resource and Energy Efficient Next-Gen Sawmills

GREEN-SAW
High-speed filming of a sawing cut

The project develops knowledge, methods, and equipment for more precise and resource‑efficient sawing using real‑time control based on CT data and cutting forces. It aims to create prototype equipment, tools for thinner cuts, and demonstrate at least a 0.2 mm reduction in kerf width to improve precision, quality, and sustainability.

Background

Problem and potential: Sawing of logs generates 10–15% sawdust, which is usually burned, resulting in loss of economic value and stored CO₂. A reduction of kerf width by 1 mm could reduce Sweden’s CO₂ emissions by up to 0.4%.

Research solution: The project develops models for cutting processes and tool–wood interaction supported by CT technology, high‑speed imaging, and numerical simulation to optimize sawing and enable thinner tools.

Impact and funding: The aim is to increase yield, reduce energy consumption, and strengthen climate benefits throughout the value chain. The project funds Frank Schleicher’s doctoral education at LTU, with supervision from LTU and funding through the Swedish Energy Agency.

Impact Goals

The project increases resource efficiency and climate benefits in the Swedish sawmill industry through real‑time controlled sawing using CT data and cutting‑force measurement. This enables narrower kerfs (−1 mm), generates +2.5 billion SEK/year in value, reduces CO₂ emissions by 225,000 tons, and lays the foundation for future high‑precision sawing.

Project Goals

The project develops knowledge, methods, and equipment for more precise and resource‑efficient sawing through real‑time control based on CT data and cutting forces. The aim is to create prototype equipment, new tools for thinner cuts, and demonstrate a reduction in kerf width of at least 0.2 mm—strengthening industrial precision, quality, and sustainability.

Target Groups

  • Swedish sawmills and the wood industry can implement the technology to increase yield and reduce energy use.
  • Tool and machinery manufacturers can develop saw tools and equipment for thinner cuts and intelligent control.
  • Research and innovation actors working with process modeling, measurement technology, and sustainable production.

     

This work is carried out with financial support from the Impact Innovation program Net Zero Industry—an initiative of the Swedish Energy Agency, Formas, and Vinnova.

Testing and inspection of concrete, binders, and natural stone

concrete testing

When materials do not perform as intended, projects risk delays and cost overruns, with consequences such as cracking, reinforcement corrosion, and deviations from applicable regulations. Often, problems are only noticed once damage has already occurred, resulting in significant financial consequences. With RISE experts and advanced laboratories, you get reliable results that meet both national and international standards.

Expertise and advanced analysis methods

At RISE, we combine research, solid experience, and advanced analysis methods to identify and prevent problems at an early stage. Our experts have extensive knowledge in the analysis of concrete, binders, and natural stone, and we work with methods such as petrographic analysis, micro-X-ray, and testing of shotcrete and surface protection products to ensure the quality and function of the materials.

Testing and auditing

RISE performs both accredited and non-accredited testing, and our laboratory is accredited for over 70 methods within concrete, binders, ballast, and natural stone. At our field test sites, concrete is exposed to natural environments, with and without the influence of sea and road salt.

RISE is a notified body for several areas within the Construction Products Regulation (CPR). The tests that manufacturers declare in their DoP and that the notified body reviews during audits are covered by the tests we can perform in our laboratory. This means that our auditors at the customer's premises have extensive knowledge and expertise, even when it comes to the tests themselves. We can assist with the entire chain from sampling and testing to auditing.

Why choose RISE as your partner?

With RISE, you get an independent partner that combines in-depth technical expertise with broad practical experience in the cement and concrete industry. We offer both comprehensive solutions and individual testing/analysis. We collaborate with construction companies, material manufacturers, and other players throughout Sweden.
