  • On January 10, 2012 we started
  • [Metropolia Student Project Seminar 24.5.] Zero Energy Buildings, Group A

    1. 1. Presented by:Beyene,Dagim Reta, Tibebe Jaiswal, Manish Kejela, Kidist
    2. 2. Background•Thisresearch is focused on concept,trends, and ways to achieve the goal ofZero Energy Building.•Global warming and a probable energycrisis are the root cause for the initiation ofzero energy buildings
    3. 3.  Doesn’t have any universal definition. Varies from country to country. Can be generalised as the building which have the total energy output/production equals to it’s total consumption on annual basis. The source of energy is supposed to be renewable with minimum carbon foot print. Furthermore, criterias like net zero carbon footprint can be added.

    5. 5.  In Europe around 40% of all energy is consumed by buildings. Ultimately, one of the major source of Carbon dioxide. Growing concern about global warming and its impacts. Rising energy costs and energy crisis.
    6. 6. Country Low Energy TargetAustria Annual heating energy consumption below 60-40 KWh/m².Belgium 40 % lower than standard levels, 30 % lower for office and school buildingsDenmark 50% lower than the minimum requirement for existing buildings.Finland 40 % less energy consuming than current buildings.France (40 - 65 )kWh/m² depending on the climatic area and altitude.Germany By 2020 buildings should be operating without fossil fuel, energy requirements (60-40 )kWh/m² .Netherlan 50 % reduction by 2015, 25 % reduction by 2010 bothds compared to current code plans.Sweden 20% decrease by 2020, 50% decrease by 2050 compared to 1995 consumption level.Source: SBI (Danish Building Institute), European Strategies to move towards very low energybuildings, 2008
    7. 7. • The BDCES groups the U-factor values based on three geographical zones in South Korea, • central, south and Jeju Island.Table 3 Maximum Heat Transmission (U-factor) of BuildingEnvelope Components by Region
    8. 8.  The carbon reduction target of 2020, which aims to reduce energy consumption by 30%. low carbon green growth. (Active concept that advances the growth of new power source)

    19. 19.  Using photovoltaic energy generation and better building mechanism. Outer walls-234 mm thick and laminated of new ceramics(PALC)of 80 mm thick. Windows-triple glass sash, which improve thermal loss and air tightness.
    20. 20.  Excess power sold to power companies. Air conditioning-heat pump system, hot water heated during night time to benefit from lower electric cost and reduce power consumption at the day time at peak cost.
    21. 21.  Energy consumption of house is 8900kwh/year Pv generation is 8000 kwh/yr
    22. 22.  Heating -1600kwh  Cooking -1200kwh  Domestic hot water-2100kwh  Heating and appliances-4000kwh  Total -8900 kwh Additional cost 70,000 euro Saving from running cost 3000 euro/yr
    23. 23.  Greenest urban development on earth 4.63 million euro. 1000 houses Solar energy main source of power Lithium ion storage batteries, power to store for a week Planned to be in total use by 2018
    24. 24.  Energy efficient office building used by the city of Helsinki Environment centre. Completed in September 2011 A perfect example of energy efficient building in Finland. Total purchased energy consumption of about 70 kWh/m^2 Total energy Production was about 17 kWh/m^2.
    25. 25.  the window filled with Argon rather than normal air in order to improve the insulation. Roof has been designed in such a way that it utilises the daylight as much as possible . fig: Roof structure of Viikki Environment Centre
    26. 26.  Solar panels mated with the façade for maximum energy production. Extensive use of wood to reduce carbon foot print. The ventilation system is Zero-specific and equipped with heat recovery system with almost 75% efficiency. All these renewable energy production for almost 20% of the total energy consumption Unique roof design to utilize maximum daylight and reduce lighting energy requirements The energy consumption for lightening fig: Southern Façade of Viikki Environment Centre. is further reduced by using LED lights.
    27. 27.  Each country’s understanding of ZEB concept is unique. All countries emphasize the importance of energy efficiency measures. adopting such requirement the countries want to eliminate low-quality ZEBs. And significant influence of the occupants on the energy use in buildings.
    28. 28.  Definition that aims:- ◦ minimize peak loads and ensuring a very low energy demand of the building. ◦ for user-friendly buildings.  Not too much work or complicated. ◦ Passive or Very low energy buildings  cost-efficient solutions for achieving zero energy buildings.
