When is the best time to renovate, reclaim, or replace windows?

Windows are resource- and energy-intensive to manufacture, and at the same time, they are difficult to reuse because they must meet high standards for energy performance, airtightness, safety, and indoor air quality, among other things. Join us for a webinar that addresses the question: When is it best to renovate, reclaim, or replace windows?

Note that this webinar will be held in Swedish.

Currently, there are no standardized methods for assessing remaining technical service life and actual performance, which means that functional windows are often replaced unnecessarily. This leads to increased environmental impact, more waste, and wasted resources.

In the RISE-led project Windows – repair, renovate, upgrade, circulate? we have developed a practical methodology that combines systematic inventory, laboratory testing, and life cycle analysis (LCA) to provide property owners, consultants, and contractors with reliable guidance on the question: when is it best to renovate, reclaim, or replace?

The project was carried out by RISE in collaboration with Förvaltningsaktiebolaget Framtiden, Stena Fastigheter Malmö AB, and the City of Gothenburg.

Contents

During the webinar, you will gain:

  • An understanding of property owners’ backgrounds and needs regarding various window measures
  • A practical guide and concrete tools for assessing whether windows should be renovated, reused, or replaced
  • Knowledge of how to link inventory results to actual technical performance
  • Insight into what life cycle analyses reveal about the climate impact of different options
  • Input and insights from property owners planning to apply the methodology

Who is it for?

The webinar is aimed at property owners, building consultants, contractors, municipalities, and other stakeholders involved in the maintenance, renovation, or remodeling of existing buildings.
