Background: A refurbished and improved building stock in the EU will help pave the way for a decarbonised and clean energy system, as the building sector is one of the largest energy consumers in Europe and is responsible for more than one third of the EU's emissions. But only 1% of buildings undergo energy efficient renovation every year, so effective action is crucial to making Europe climate-neutral by 2050. Currently, roughly 75% of the building stock is energy inefficient, yet almost 85-95% of today’s buildings will still be in use in 2050. Renovation of both public and private buildings is an essential measure in this context, and has been singled out in the European Green Deal as a key initiative to drive energy efficiency in the sector and deliver on objectives.

Aligned with the European Renovation Wave (EUR-Lex - 52020DC0662 - EN - EUR-Lex (europa.eu)) which aims to increase current renovation rates in Europe, this thesis looks at an established case study on the NTNU campus Gløshaugen.
Short project/thesis description:
The case consists of a building complex of two high-rise buildings and three connected low-rise buildings, locally known as “Sentralbygg 1” and “Sentralbygg 2”. The case is well suited for retrofit considerations as it contains existing buildings in need of energy upgrading that are of educational typology and publicly owned. With that, the case satisfies the requirements for one of the three target groups of buildings according to mentioned Renovation Wave (see section 4).
The research questions of this thesis target the uncertainty of how the choice of retrofitting packages and measures is influenced by restrictions given by heritage value constraints – both on the interior and exterior. All buildings looked at are classified as having protection class C according to Norwegian definitions.
The analysis’ potential is great as the difficulty of dealing with protection restrictions is merely mentioned in the Renovation Wave without there being any suggested solutions:
“Renovation must respect design, craftsmanship, heritage and public space conservation principles.” (p. 4)
“Specific skills are also needed for the safe management of historical buildings and safeguarding their heritage value.” (p.14)
“…while safeguarding cultural heritage.” (p. 26)
Summary:
- Focus on retrofitting packages and measures with a focus on energy.
- Focus on retrofitting under heritage constraints and implications.

Short project description: Existing buildings that are to be retrofitted, with their specific location and geometry, are facing technical obstacles that can be difficult to avoid within reasonable measures. Since in this case it is difficult to determine the quality of existing materials and components at the beginning of the building process, retrofitted buildings are more exposed to unpredictable costs along the way.
In addition, the pre-approved detailed solutions are often developed to be implemented in new constructions. These challenges often stop retrofitting projects from being started/completed.
The main goal of the project is to find sustainable retrofitting scenarios as well as optimized and detailed solutions based on specific selected cases, such as complex buildings with the office and university function, which can be considered as pilot ZEN projects related to the development of NTNU campus; sustainable solutions which in turn can be considered for other buildings and effectively increase the frequency of sustainable retrofitting projects in Norway.
