GENERAL OVERVIEW
Energy teams building is a net positive building in terms of electricity and net zero in terms of water. We supply all produced electricity to the smart-grid, and power up the village in case of blackout. Our building follows ‘Energy saved is energy created’ principle. We have reduced our consumptions drastically by means of design and not retrofits. We have a green core, which is our green house. This activates our natural ventilation system and helps insulate our building in summer and winter. It shades the building in summer preventing direct heat gain by insolation in summer. Correspondingly, it helps to heat the building in winter by trapping heat, acting as a glasshouse. Guidelines for maximized solar utilization were given to all building teams post shading analysis simulation and solar heat gain radiation simulation. Building teams were advised to orient, put BIPV’s and shade their buildings accordingly. We also provided bio-composter guidelines to Nature and Food team, as it is more efficient that they produce their own biogas considering large volumes of bio-waste they are producing and large number of fertilizers needed on regular basis.

CITY SCALE AGENDA
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions.
Climate change impacts: Melting ice and rising seas
Extreme weather, shifting rainfall
Impact on Health
Change of location of many Spieces.. Effect of temperature agriculture, forestry, energy and tourism.
Costs for society and economy

Consequences for Europe
EU climate action Key EU targets for 2020 20% cut in greenhouse gas emissions compared with 1990 20% of total energy consumption from renewable energy 20% increase in energy efficiency Key EU targets for 2030 At least 40% cut in greenhouse gas emissions compared with 1990 At least 27% of total energy consumption from renewable energy At least 27% increase in energy efficiency Long-term goal By 2050, the EU aims to cut its emissions substantially – by 80-95% compared to 1990 levels as part of the efforts required by developed countries as a group.

CITY SCALE AGENDA
RENEWABLE ENERGY IN GENT Data provided by JIC portal of Flander’s Municipality on geopunt.be indicated that several have been planned for the city of Ghent namely: photovoltaic panels, ground connected heat pumps, wind turbines and electricity production from specific biomass flows. However Ghent Muide seems to fall under a schism of these services. Our aim is to make the village completely self sufficient and help the bigger vision of Ghent to be self-sufficient.

VILLAGE SCALE CONCEPT
We are making use of the abundant solar energy for majority of our electricity production.Catchment is on the roof, walls and windows. Building Integrated Photovoltaics are placed at suitable locations based on solar insolation simulations done. Kitchen waste from the whole village is utilized to create bio-gas, this fuel is used for cooking purposes directly in the building offsetting electricity demand. People on the Gym also manually create energy, getting more aware of how difficult it is to produce.

ENERGY AND THE CITY (BLURB - ACHTERFLAP) Our project is a combination of low and high tech approaches. We think about the environment as an interdependent system, where nature beneficially meets human achievement and where humans are nature. The inspiration for our project was found in the site itself where the local community has initiated the creation of an urban farm on an abandoned territory. We want to support them and promote this idea through the use of natural sources of energy. By storing waste and manure in a biogas tank we can power the stoves of several housing units. To achieve maximum energy efficiency we propose to install solar panels on top of existing roofs and include those systems in new development. Apart from that, heat pumps can be installed underneath new buildings in order to provide them with heat and cold of the ground. Beside nature, humans are also included into energy harvesting process. Energy harvested from human movement in the gym area can supply lighting for the place. In addition to that we design a greenhouse which crossing all appartments and provide natural cooling and ventilation for these units. Our building is the new sustainable machine for living. By integrating different energy sources, functions and their interconnections, the building itself serves as a power plant.
