2 Agenda Dipl. Engineer, Dipl. Industrial-Engineer Peter Vespermann The engineering company PPSI Information about our mission and activities Solutions Examples of projects Time for questions 2

3 Engineering Company PPSI PPSI is a Consulting Company from Berlin in Germany. We have been successful for more than 20 years. 3

4 Engineering Company PPSI Our business areas Energy efficiency consulting Apartment buildings / multiple-family dwellings Terraced houses as well as semi-detached houses and single family houses Freehold flats Commercial properties Energy efficiency consulting for enterprises in the manufacturing and the service sector Auditing companies according to EN EN

5 Engineering Company PPSI Our business areas Education and advanced training for energy efficiency and renewable energy in Germany and in other countries Finding solutions and evaluating energy efficiency issues 5

6 Engineering Company PPSI Target groups Architects Engineers Building designers Tradesmen Local authorities 6

7 Engineering Company PPSI Our philosophy Guiding principle: 7

8 Engineering Company PPSI Our way of working Record the actual data Measure Calculate Experience Evaluation of data collected Implementing an individual and sustainable concept for energy efficiency and renewable energies Construction supervision Consultations for subsidisations e. g. German Development Bank (KfW) or German Federal Office of Economics and Export Control 8

9 Engineering Company PPSI Our way of working The calculations are performed by different software programs: Energy consumption of buildings Calculate heating and cooling systems Calculate solar thermal systems (for domestic hot water, process heat, heating, cooling etc.) Calculate photovoltaic systems Calculate ventilation systems We work with our own measurement systems and specific analysis tools for measuring data 9

10 Energy efficiency example building unused energy potentials 28 % replacement of doors and windows 12 % roof insulation or insulation of upper levels 17 % wall insulation 16 % floor slab 7 % Heat recovery systems for ventilation 20 % 10

11 Where energy is lost in buildings Energy efficiency demonstration: before / after comparison before: 28,684 kwh / per annum roof 12,120 kilowatthours (kwh) per year after: 9,134 kwh / per annum roof 3,000 kilowatt-hours (kwh) per year doors and windows 4,700 kilowatt-hours (kwh) per year doors and windows 2,520 kilowatt-hours (kwh) per year floor slab 1,764 kilowatt-hours (kwh) per year wall 10,100 kilowatthours (kwh) per year floor slab 714 kilowatt-hours (kwh) per year wall 2,900 kilowatt-hours (kwh) per year 11

12 Examples Single family house Basic information: Year of construction: 1896 Living space: 375 m² Primary energy consumption: Before: 395 kwh/m² per year After: 158 kwh/m² per year Measures: 1. Gas condensing technology 2. Solar panels 3. Basement insulation 4. Roof insulation 5. Exchange of windows Energy savings: 61 % CO 2 -reduction: Kg / per year 12

13 Examples Apartment building with 12 flats Measures: 1. Insulation of the facade 2. Insulation of basement ceiling 3. Insulation of the top floor ceiling 4. Insulation of the roof 5. Replacement of the windows Basic information: Year of construction: 1957 Living space: 737 m² Primary energy consumption: Before: 266,5 kwh/m² per year After: 125,9 kwh/m² per year Energy Savings: 53 % CO 2 -reduction: Kg / per year 13

14 Examples Energy Efficiency Consulting for Small and Medium-Sized Enterprises (SMEs) Health Care Centre Stephanus-Stiftung- Ulmenhof Energy savings: 42 % Measures: Photovoltaic systems on two buildings Combined thermal power station 14

15 Examples Energy Efficiency Consulting for Small and Medium-Sized Enterprises (SMEs) Retail Supermarket Project: Energy Efficiency Consulting Support the systematic optimization for small and medium-sized enterprises (SMEs) by using the funding of the German Federal Office of Economics and Export Control (BAFA). Measures: 1. Replacement of light 2. Replacement of coolingsystem / heatingsystem Energy savings: 51 % 3. Replacement of ventilation system 15

16 Australian s cities In the past six years, 1.5 million homes have had solar cells installed on their rooftops, which in Western Australia is 22 per cent of all house-holds. 16
