Passivhaus

  1. 1. BUILDINGS:Energy Consumption Status andPassive House StandardAlice Corovessi CoFounder –CoOwnerT. +302117708899 F. +302117708889info@passive.gr - alice@passive.gr
  2. 2. Source :European Commission EnergyBuildings are responsible for :Energy performance of buildings is key to achieve the EU Climate &Energy objectives, namely the reduction of a :• 40% of energy consumption• 36% of EU CO2 emissions• 20% of the Greenhouse gasesemissions by 2020• 20% energy savings by 2020
  3. 3. Source :European Commission EnergyImproving the energy performance of Buildings :Is as Cost effectiveof Fighting againstClimate ChangeA Way to EnergySecurityWe have LessCarbon EmissionsAlso Creating JobOpportunities
  4. 4. Energy Pyramid41% of all energy in EU is used bybuildings33% of all energy in EU used fortransport26% of all energy in EUis used by industry
  5. 5. Energy Status in Buildings68% of energy consumption in buildings isused for heating and cooling80% of energy consumption is used in smallbuildings < 1000 m2
  6. 6. Now it is easy to understand why the “Passive HouseStandard” is the new TREND !!.
  7. 7. What is the “Passive House Standard”The term “passive house” (Passivhaus in German) refers to therigorous, voluntary, “Passivhaus standard” for energyefficiency in a building, reducing its ecological footprint.It results in ultra-low energy buildings that require littleenergy for space heating, cooling and hot water.The standard is not confined to residential properties. Severaloffice buildings, schools, kindergartens, supermarkets,hospitals, etc have also been constructed to the standard.
  8. 8. photo source: www.econews.gr“Passive House” design is not an attachment or supplement toarchitectural design, but a design process that is integratedwith architectural design.Although it is mostly applied to new buildings, it has also beenused for refurbishments.
  9. 9. The RequirementsThe Passivhaus standard requires that the building fulfillsthe following requirements:The building must be designed to have an annual heating demand ascalculated with the Passivhaus Planning Package of not more than15 kWh/m² per year (4746 btu/ft² per year) in heating and15 kWh/m² per year cooling energy OR to be designed with apeak 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 … ”
