Increase Sustainability in Buildings Through Public Procurements: The PROLITE project for Lighting Retrofit in Schools

The Public Procurement has always been a demand-side policy measure with great opportunities in terms of spurring innovation at the scale of products and/or services. A support for a sustainable development in the field of energy and buildings may came from different types of Public Procurement: Green Public Procurement (GPP), Sustainable Public Procurement (SPP) and Public Procurement of Innovation (PPI). Within this framework, the paper presents a case study where PPI has been used to promote the development of innovative solutions for upgrading school buildings in terms of increased energy efficiency and sustainability.
