Energy Efficiency in Public Buildings
EU Policy Framework for Energy Efficiency EU Energy and Climate Package 2030 40% reduction in GHG emissions (reference year: 1990) 27% share of renewables in final energy consumption 27% reduction in total primary energy supply (reference year: 2005) EU Energy Efficiency Directive Folie 8 obligation for public sector to procure energy-efficient products and services refurbishment of public building stock: each year, national governments have to refurbish 3% of their buildings public sector as a role model promotion of energy services, Juli 2011
Public Building Stock Germany 190,000 public buildings in total 4,200 buildings owned by the federal government 6,500 buildings owned by the Länder 176,000 buildings owned by municipalities cost for implementation of EU 3% refurbishment rate: 40 billion Berlin 7.100 buildings of State and district administrations energy costs: 107 million per year energy demand of State buildings: 820 GWh/a (= energy demand of almost 400,000 households in Berlin per year)
Obstacles and Challenges in Public Buildings and Budgets Savings in the long run call for short-term investments High need for investment vs. constrained public households Field of activity for... public-private cooperation integration of private services Energy service provider brings in... Investment Know-how / experience Benefits for building owner: Reduction in operating costs Operational reliability positive effects on the environment
Energy-Saving Potential in Public Buildings Example of hospitals: On-site generation: use of condensing technology, CHP unit, absorption chiller, switch from steam to hot water (20-50%) VAC: needs-based operation of ventilation and air-conditioning system (time flow and volume flow) (20-50%) Lighting: T5-EVG, LED (20-50%) photo: isave photo: econlux
