Project 8. Project of Nearly Zero Energy District [nZED] for (Nil Juvanteny i Vanessa Gàlvez). The main objective of this project is to achieve a nearly zero energy district [nZED] for the city center of Schiedam. The most important idea of the project is to develop a model that can be exported to any neighborhood, district, area of the city, independently if it is rich or poor, big or small. The principle of “nearly zero energy” means a very high level of energy performance that is traduced in low energy consumption which should be covered using renewable sources. These renewable sources are used not just to cover the energy consumption but also to sell the surplus and make profit from that.

  1. 1. The way to Nearly Zero Energy Buildings [nZEB] in the Public Sector – Recommendation Guide Nil Juvanteny Planagumà Tutor in Girona: Joaquim Meléndez i Frigola Tutor in Schiedam: Resie Beulen
  2. 2. Actual Problem –What we want to solve? • Climate change • Energy dependence • Empowering renewable energy • Energy efficiency
  3. 3. Regulations • Energy Performance of Buildings Directive [EPBD]  All the existing public buildings and facilities must be nZEB on 2018. New ones must be built as nZEB from 2020. • ISO 50001 Has the objective of establish a minimum requirements in order to keep improving systematically the efficient use of energy in buildings. • 2012/27/EU  It establishes a common framework of measures to promote energy efficiency in the European Union.
  4. 4. Why are there all of these energetic regulations in buildings? • From all the world energetic consumption  Almost 50% is consumed by buildings. • In the public sector  More than 50% of the consumption is from buildings, the rest is lighting, transport, signalling, etc. • Buildings have a GREAT POTENTIAL FOR SAVINGS without affecting the quality of life.
  5. 5. Which is our contribution to solve the actual problem? • Elaboration of a RECOMMENDATION GUIDE for the public administrations in order to convert the public equipment and facilities to nZEB.
  6. 6. What is a nearly Zero Energy Building [nZEB]? • Zero emissions  All the energy used is green. • Zero energetic dependence from outside  All the energy used is produced on-site. • It has a big performance  High energetic efficiency, it uses as less as energy possible and it is used in the maximum efficient way.
  7. 7. OBJECTIVES • Give ADVISE and SUPPORT to authorities, workers and users of public equipment and facilities. • Show the way to achieve a nZEB in public sector. • Increase the energetic efficiency, reduction of energetic dependence, reduction of emissions and empower renewables energies.
  8. 8. Which is the innovation of this guide? Citizens participation Renewable energy Government Share Information  Open Data SMART CITY
  9. 9. How this guide has been developed?Which premises have been adopted? It must be understandable for anyone – no need to be an expert It englobe all the public equipment and facilities It englobe all the energetic systems of a building
  10. 10. Strategic Plan – 5 STEPS 1- Information 2- Study and analysis 3- Objectives4- Strategic Plan 5- Monitoring, control and verification
  11. 11. Strategic Plan – STEPS 1 and 2 1. Information gathering  It consists in an audit, take data and measures, talk to the workers and users, etc. • The objective is gather as much information as possible. 2. Study and Analysis  It consists in analyse further all the data and information obtained from the first step. • The objective is to know exactly which is the initial point, the actual situation.
  12. 12. Strategic Plan – STEPS 3 and 4 3. Objectives  From the study and the starting point, fix different objectives or achievements (points of control) along the following months or years focusing all of them in the final objective which will be always the nZEB. 4. Strategic Plan  Taking account the objectives, elaborate a strategic plan, step by step, proposing some measures and explaining how these objectives will be achieved. • Between a big amount of possible measures or actions, decide which ones fix better with the objectives from step 3 and execute them.
  13. 13. Strategic Plan – STEP 5 5. Monitoring, control and verification  This step will work in parallel with the strategic plan. • Objectives: • Measure everything. • Control and verification all the objectives. • Detect when something is working wrong. • Propose solutions to these problems. • Ensure that everything is working properly.
  14. 14. How the proposals/measures have been divided? 1- IMMEDIATE ACTIONS • Low inversion, immediate and easy. 2- KNOWLEDGE OR INDIRECT ACTIONS • Control and monitoring, medium inversion,. 3- DIRECT ACTIONS • High inversion, amortization along the time, difficult action. Help from experts. 4- PRODUCTION ACTIONS • Destined to production, high inversion and long amortization. Help from experts. 5- SMART CITY ACTIONS • Actions destined to Smart City policies.
  15. 15. Another classification - Energetic Labels Conditioning Lighting Isolation Electric system Control and monitoring Production
  16. 16. ACTIONS 1- IMMEDIATE ACTIONS • Installation of elements for solar control. • Optimization of electric power contracted. • Reduction of thermal losses by air filtration. • Introduction or improvement of zoning. • Contract energy from green energy. 2- KNOWLEDGE OR INDIRECT ACTIONS • Control of radiators temperature. • Humidity control. • Lighting sensors, control of natural light. • Installing an Energy Control System. • Installation of devices of light off.
  17. 17. ACTIONS 3- DIRECT ACTIONS • Installation of green covers. • Reduction of heat losses for windows, doors, walls and roof. • Installation of capacitor bank. • Installation of solar ducts. • Inertia tank installation 4- PRODUCTION ACTIONS • Installation of photovoltaic solar panels. • Installation of solar thermal panels. • Installation of a geothermal energy system. • Small wind power installation. • Replacing conventional boilers for biomass boilers
  18. 18. 5- SMART CITY ACTIONS Installation of points of charge for EV • It requires public equipment with space for photovoltaic solar panels. • Overstate the installation in order to have a surplus of energy. • Put this surplus at the disposition of citizens in order to charge its EV at very low price. • Benefits? • Satisfied population • Potentiation of EV • Potentiation of renewable energy.
  19. 19. 5- SMART CITY ACTIONS Construction of a civil solar plant • It requires public equipment with a big space for photovoltaic solar panels. • The plant is funded for citizens as small investors. • Energy is sold to the electric company. • Projects like that There is a ensured 3% of benefits for the investors. • Benefits? • Satisfied population • Potentiation of renewable energy.
  20. 20. CONCLUSIONS • Smart City concept  Good idea to involve smart city concepts to any project from any area. • Energy and Smart City policies are really close There is a lot of opportunities and work to do in this direction. • Involve and sensitize the population is a necessary tool to achieve the energetic objectives.
