A Visionary Infrastructure Solution for enclosed community living

This vignette is set in 2111 after the worst-case global warming scenario has come to pass; average global temperatures have risen by
13 °C and sea levels have risen by eleven metres. The equatorial
regions of the globe are uninhabitable. The more temperate regions,
reduced in area due to sea-level rise, are much hotter than at present, and suffer highly unpredictable swings in weather patterns;
populations have hence migrated towards the remaining habitable
land. The only option for the majority is to live underground, underwater or upon the surface of the water in enclosed capsules – although some communities could cling on to the surface in currently
uninhabited areas such as Greenland, Siberia and Antarctica. the
main technological issue for these underground and underwater
communities will be lack of solar energy and natural light.
Vignette Vision
This study builds on multiple
subterranean and sub-aquatic
systems. Some are real-world
operational examples of underground living, whereas others
are visionary plans.
The vignette is set in a context
where life outside sheltered
community accommodation, is
difficult.
It envisions a modular (and so
extensible) utility infrastructure
which is multi-functional, secure
and environmentally friendly.
The HVAC plus (which includes
water and electricity) delivers
sufficient thermally comfortable
air, power and water for basic
needs to modular dwellings within the community.

A utility distribution system inspired by
existing methods of heating, ventilation and
air conditioning (HVAC) systems
HVAC systems have developed
since the industrial revolution into a
world-wide industry providing thermal comfort and indoor air quality
for small to large enclosed areas.
HVAC systems are integrated with
the environment for the input of
fresh air and the expulsion of
waste.
Such systems are modular, extendable resource and waste carriers
with chemical filters to maintain
healthy enclosed living.
Low voltage electricity would be
transmitted continuously over
these systems, and then picked
up ‘wirelessly’ and consumed by
devices which transform the
electricity into lighting or power.
Water would be condensed for
drinking and essential uses only;
substitutes for other uses of water such as laundry and personal
hygiene would be required. Reservoirs of rain water or desalinated sea water could be created
for community use.
The All-in-One vision is to extend
these HVAC systems to include
water and electricity transmission to
create sustainable multi-purpose
utility systems.

with little movement beyond their home community, so
the need for virtual communication will become
paramount – as will the indoor cultivation of food

underground rice production.

Society
Floating communities could join together into cities
and nations for trade and socialisation. The
underground and underwater pathways will be used
by battery electric vehicles for the transfer of goods
and services wherever practicable, so as to minimise
the need for surface transport.
Modular integrative design of community level
secure utility distribution systems such as HVAC
+ require massive investment in new technologies
and a consensus in society of their need and an
understanding of their implications for future
lifestyles.
