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.

11. How is the consumption distributed and
which factors affect to it?

12. What do we propose to reduce energy demand ?
and how do we do it?

13. How do we arrive to know the consumption
for a community ?

14. How do we arrive to know the consumption
for a flat?
