c_life will be a carbon negative, sustainable city quarter in Helsinki that demonstrates how to transition to zero and negative carbon through 9 ideas: 1) Becoming a "living factory of ecology" that produces innovation for people and the environment 2) Establishing a Climate Neutral District with coordinated sustainability efforts and a carbon accounting system 3) Reducing on-site emissions 40% and offsetting the remainder through an off-site wind farm 4) Designing flexible, efficient buildings that use low-carbon materials and reduce embodied carbon 55%

2. Carbon trajectory- from low to zero to negative

3. … the mix of c_life -
to contain living, leisure,
innovation and entrepreneurship
… evolving the carbon strategy -
from low2no to carbon sink
we imagine

4. … defining the tools for change -
through accessible and transparent
decision making
… triggering systemic change -
that picks up on the existing
and delivers new thinking
we imagine

5. … building replicability -
through a development that will be
an inspiration for future sites
… building excellence -
creating a city to love and a home to
identify with
we imagine

6. … enabling behavioral change -
that builds on people and their
social networks
… delivering a
credible framework -
for the economics, the policies and
the governance of c_life
we imagine

1 c_life:
city as living factory
of ecology
c_life is a lasting real time and real space
demonstration of how to live, work, play
and learn, producing innovation that
benefits people, the environment and the
economy.
c_life will be an innovation factory in
which SITRA will attract Start Ups and
Companies by creating a stimulating
environment for entrepreneurship, where
prototyping of built environment policies,
technologies and services can be
showcased.

climate neutral district:
delivering an economic
and governance
framework for change
Our proposition is to establish the Jätkäsaari
Climate Neutral District (CND).
The CND is the most efficient and cost-
effective way for c_life and other development
projects on Jätkäsaari to achieve carbon
neutrality.
The key strategies within CND are to:
• coordinate district-wide sustainability efforts
• establish a district carbon accounting system
• establish carbon neutrality policy for buildings
• create revolving fund for offset projects,
• invest in carbon abatement projects,
• develop municipal financing scheme,
• attract green co-operatives
• attract a Jätkäsaari sustainable bank
• implement 50 ways to change behaviour.

3 efficient clean energy:
reduce on site
+ produce off site
c_life has been conceived as a highly
energy efficient city block that reduces
carbon emissions by 40% in operation,
after which the remainder is tackled by an
offsite wind farm funded by the
development.

• narrow floor-plates
• structural modulation and service/utility
design buildings ducting are suitable for residential, retail or
commercial uses
for change
• transparency for the public realm

structure are reduced by 55%, using
use resources efficiently: • timber for structure and finishes
low carbon materials • lightweight façades (punched windows)
• minimum impact concrete foundations
and structure
• low carbon finishes

embody the spirit of the master plan –
creating not just buildings but places that will be • c_life as catalyst for sustainable urbanism
an inspiration to subsequent blocks • quality – sensuous architecture creates
well- being for the individual

7 empower people:
engage + incentivise + benefit
communicate + lead
People, and their contexts, social
networks, habits and beliefs are crucial
tools for creating sustainable change in
behaviour.
Up to 50% of the carbon footprint is
associated with lifestyle choices.
Approach:
• developing engagement and awareness
strategies
• using technology that assists them in
making decisions
• producing positive reinforcement loops
for people who live, work and visit c_life
• using the community as a knowledge
network to share best practice
• demonstrating leadership

move smartly:
live / work +
walk, cycle and tram around +
go car clubbing
The objectives of the transport strategy
are to reduce the need to travel, enhance
mobility and reduce emissions.
Approach:
• incentivise co-location of live and work
• provide low carbon public transport
• provide affordable zero carbon car clubs
on each urban Block

9 produce food:
have your pocket green house
A person living in c_life will be able to
reduce its carbon emissions associated
with food consumption by 30% compared
to a typical person living in Helsinki.
Approach:
• growing up to 50% of your green
vegetables in pocket greenhouses placed
in each dwelling
• shifting to buy local
• changing behaviour.
