New solutions to reduce greenhouse gas emissions through energy efficiency of buildings of special importance - Hospitals.

Saving energy has an important role in the concerted actions to protect the planet from the effects of global warming, particularly the energy consumed by the existing buildings (with various energy consuming functions, inefficient energy), by implementing environmentally friendly solutions. The present paper emphasizes the need to include elements to stimulate the renovation of the existing buildings and of their energy efficiency in the national strategies, these constructions being important energy consumers. The research started with two case studies (2 hospital buildings) dating from 70-80s, with the aim to be energy efficient and modern constructions in Eastern Europe. In the presented best practice model, significant reductions in greenhouse gas emissions, primary energy consumption along with the use of renewable energy have been achieved by transforming some energy-inefficient buildings into intelligent buildings. Thus, the authors propose a new stake: "70-70-70" for similar buildings.
