Buildings energy consumption status and passive house standard

  1. 1. BUILDINGS:Energy Consumption Status and Passive House Standard Alice Corovessi CoFounder –CoOwner T. +302117708899 F. +302117708889 -
  2. 2. Source :European Commission Energy Buildings are responsible for : • 40% of energy consumption • 36% of EU CO2 emissions Energy performance of buildings is key to achieve the EU Climate & Energy objectives, namely the reduction of a : • 20% of the Greenhouse gases emissions by 2020 • 20% energy savings by 2020
  3. 3. Source :European Commission Energy Improving the energy performance of Buildings : Is as Cost effective of Fighting against Climate Change Also Creating Job A Way to Energy Opportunities Security We have Less Carbon Emissions
  4. 4. Energy Pyramid41% of all energy in EU is used by buildings 33% of all energy in EU used for transport 26% of all energy in EU is used by industry
  5. 5. Energy Status in Buildings68% of energy consumption in buildings is used for heating and cooling80% of energy consumption is used in small buildings < 1000 m2
  6. 6. Now it is easy to understand why the “Passive House Standard” is the new TREND !! .
  7. 7. What is the “Passive House Standard”The term “passive house” (Passivhaus in German) refers to the rigorous, voluntary, “Passivhaus standard” for energy efficiency in a building, reducing its ecological footprint. It results in ultra-low energy buildings that require little energy for space heating, cooling and hot water.The standard is not confined to residential properties. Several office buildings, schools, kindergartens, supermarkets, hospitals, etc have also been constructed to the standard.
  8. 8. photo source:“Passive House” design is not an attachment or supplement to architectural design, but a design process that is integrated with architectural design.Although it is mostly applied to new buildings, it has also been used for refurbishments.
  9. 9. The RequirementsThe Passivhaus standard requires that the building fulfills the following requirements:The building must be designed to have an annual heating demand as calculated with the Passivhaus Planning Package of not more than 15 kWh/m² per year (4746 btu/ft² per year) in heating and 15 kWh/m² per year cooling energy OR to be designed with a peak heat load of 10W/m². Total primary energy (source energy for electricity and etc.) consumption (primary energy for heating, hot water and electricity) must not be more than 120 kWh/m² per year (3.79 × 104 btu/ft² per year).
  10. 10. The “Passive House Standard” is the only closest to the “Zero Energy Standard”These days it is very easy to accomplish “Zero Energy Building” using the “Passive House Standard” “ More home … less energy … more life … ”
