PEDs can include
All types of buildings present in the urban environment andthey are not isolated from the energy grid.

Goal of a PED requires
Improving energy efficiency
Cascading local energy flows by making use of any surpluses
Using low-carbon energy production to cover the remaining energy
use.

Basic principle of PEDs
Create an area within the city boundaries, capable of generating
more energy than consumed.

Basic principle of PEDs
Agile/flexible enough to respond to the variation of the energy market
because a PED should not only aim to achieving an annual surplus ofnet energy.

Basic principle of PEDs
It should also support minimizing the impact on the connected

centralized energy networks
by offering options for increasing onsite load-matching andself-consumption, technologies for short and long term
storages, and providing energy flexibility with smart control.

Groningen
To achieve this energy transformation, thecity council of Groningen adopted in 2011 aMaster Plan aims at making Groningen
energy neutral by 2035.
“Groningen Energises 2015-2018” completed
this political willingness followed by the 2017
“Next City” plan and its core objective ofturning the city of Groningen into a real-lifelab for energy transition.
As member of the Global Covenant of Mayors
for Climate and Energy, Groningencommitted to reduce by 70% its gas
emissions in 2030 while establishing asustainable use, consumption and energy
production.

PED Implementation – Groningen
Retrofitting of residential buildings (floors, roofs, fronts, windows,
smart thermostats and sensors to real-time measuring of energyconsumption…) in order to maximise infrastructure performance.
Solar panels will be installed on the roofs of some buildings andcar parks. In addition, Solar thermal panels will support
geothermal heat pumps which are directly connected to thegeothermal district heating system.

The surplus of thermal energy produced by some residentialbuildings will be stored and used during energy demand peaks.
On the other hand, biogas technology will be used to collect and“digest” -under high pressure and thanks to bacteria-, waste andwaste water produced by public sport and catering facilities.

Bilbao
According to Bilbao’s Strategy for Sustainable
and Integrated Urban Development, Zorrotzaurre
will become a residential and business district in
the future.
Framework for deploying and testing newsustainable concepts, principles and solutions
that will be used as an example for the whole city.
An initial district scale vision has been developedby the city:
The island will be accessible by zero-emissions
vehicles only and the idea is to implement a zeroemission energy supply scheme with 100%
electric public transportation.

Zorrotzaurre island

5,500 new homes, 150,000 m2 of office spaces, citizen spaces(154,000 m2) and social and cultural facilities (93,500 m2)#4DH Forumgenku@tcu.ac.jp

Amongst other implementations, interactive bus
shelters will provide information on the energy
flows, storage and local renewable generation, aseating area with weather protection, and manyother functionalities for citizens.

PED Implementation - Bilbao
The local PED will be developed in three locations as part ofZorrotzaurre island: North, Centre and South.
The three areas are connected via a geo-exchange loop which
is a system that will use geothermal and hydrothermal
renewable energy.
The loop covers the thermal demand of the PED locations andto export the surplus to the rest of the island and, eventually,outside the island.
