Case study: Retrofitting public buildings

The purpose of this case study is to describe the in-house model, which has paved the way for the expansion of energy renovation projects to include long-term energy efficiency achievements without the use of construction funds. The Model has been named the BVE Model BVE stands for the Calculation Model for Assessment of Energy Renovation (Beregningsmodel til Vurdering af Energirenoveringer)

Holbaek Municipality and the energy utility SEAS-NVE have developed an efficient in-house model to achieve attractive financing of energy renovation projects with both short and long-term payback periods. The model enables the Municipality to engage in comprehensive energy renovation projects taking several factors into account, such as work environment and indoor climate. The model also enables SEAS-NVE to implement energy savings according to National and European energy efficiency obligations as an energy-supply Company.

SEAS-NVE and Holbaek Municipality developed the BVE-model, as a method to spot buildings with renovation potential. They call this the BVE-model, and it is a systemic assessment of the building including a financial evaluation. On the basis of this it is possible to undertake projects completely financed by Energy loans.SEAS-NVE and Holbaek Municipality have worked closely for a long time, both on an operational level as well as on strategic areas.
