CAN INTELLIGENT
BUILDINGS PROVIDE
ALTERNATIVE APPROACHES
TO HEATING, VENTILATING
AND AIR CONDITIONING OF
BUILDINGS ?

Garrison Keillor
It was luxuries like air conditioning
that brought down the Roman
Empire. With air conditioning their
windows were shut, they couldn't
hear the barbarians coming.

The J.M Tjibaou Cultural Center (Museum of Noumea)
designed by Renzo Piano (Winner of 1998 Pritzker prize),
is a harmonious alliance of modern and traditional Kanak
architecture. Traditional thatch huts, native to the Kanak
people, inspired the design.
Piano learnt from local culture, buildings and nature.Tall
thin curved laminated iroko wood ribbed structures
supported by steel ties resist cyclones and earthquakes.
The ribs have horizontal slats which allow passive
environmental control to occur. The slats open and close
according to wind strength and direction and admit air to
a cavity which is linked to the glazed façade of the
museum.

Sustainability---- Risk or Opportunity?
– Can you afford to be sustainable?
– (Perceived) higher build cost
Can you afford not to be sustainable?
– Taxes
– Penalties
– Rising prices
– A changing environment
– Occupier awareness
– Increasing legislation
– Shareholder pressure
– New investment opportunities
– Capital value - ‘two tier market’
Hirigoyen J., 2009, Trends in responsible property, Jones Lang LaSalle

LEED Rated Buildings
 cost 6% more to build;
 have occupancy rates over 4%
higher;
 command 2-6% higher rents;
 save 10-50% in energy consumption;
 decreased operating costs;
 increased building value 10% in 2008
Hirigoyen (2009) ;Bernstein and Russo (2010)

 Reduced energy consumption
 Lower utility bills
 Lower emissions
 Lower capital costs from increased
equipment life
 Decreased unplanned downtime
 Lower risk of equipment failure
 Reduction in overtime labour costs

Environmental Design
Affects
Well-Being of People

 Low carbon buildings can be
unsustainable if the human needs
are neglected
 Healthier buildings are automatically
low carbon
 but not all low carbon buildings are
healthy workplaces

 Overheated buildings are wasteful,
uncomfortable and lower productivity
 Each deg C rise is about 8% in
energy terms in UK
 Air Quality and Temperature Equally
Important
 Emphasise Well-being and Freshness
rather than Comfort

Improved People Performance in
Green Buildings?
 Sickness Absence is reduced
 Natural light and ventilation increase
accuracy, concentration .health and
well-being ,happiness, attitudes...
 Productivity gains of up to 6-16%

Biomimetics
The abstraction of good design
from Nature

Biophilia –
How we Connect with Nature
What is Biophilia?
First described by Erich Fromm in the 1960’s, Biophilia, simply
put, is the Love of Life, or Living Systems.
American Biologist Edward O. Wilson went further with the
‘Biophilia hypothesis’ in the mid 1980’s, that we don’t just love
all things in the natural world, but we are genetically
connected to them. As humans we have a deep desire to
connect with nature whenever possible.
Our subconscious desire to be close to nature in our everyday
lives continues even in the workplace.

The Artificial Leaf
Research groups have been trying to
create artificial leafs to try and mimic
natural processes. Dan Nocero then at
MIT now at Harvard had success in 2011.
An Artificial Leaf splits water to produce
oxygen and hydrogen, use hydrogen
either as a fuel or to reduce carbon
dioxide to produce organic fuels.

Digital Botanic Architecture
The idea is not to make buildings look
like botanic organisms. It is to interlace
Nature and architecture enabling the
design of hybridized, biological
structures. The overall aim is to create
new architectural typologies
incorporating natural attributes ordered
in performance, materials, mechanics,
communications, and form.

Bioluminescence
Bioluminescence is the production and
emission of light by a living organism.
Its name is a hybrid word, originating
from the Greek bios for "living" and the
Latin lumen "light". Bioluminescence is
a naturally occurring form of
chemiluminescence where energy is
released by a chemical reaction in the
form of light emission

UV PCO
Photocatalytic Oxidation (PCO) or Photocatylisis is
the opposite
of photosynthesis.
PCO is a natural process whereby Ultra
Violet light energy reacts with the
mineral Titanium Dioxide (TiO2),
triggering a chemical process that safely
and instantly oxidizes or breaks up
organic matter at a molecular level.
As a catalyst, TiO2 continues to work
and is not consumed in the process.

Phase Change Materials
The RACUS® ceiling tile incorporates a bio-based phase
change material which captures and stores excess heat
gains from within the building which reduces the need
for air conditioning.
The phase change material is a composition of vegetable
oils and fatty acids which are microencapsulated within
an acrylic polymer shell that are embedded within the
ceiling tile.“

"As the room temperature begins to reach 24°C,
the phase change material, which starts off in a
solid state, begins to melt within the shell and
absorbs the excess latent heat from the
surrounding environment throughout the day.
As the room temperature cools to below 20°C,
the phase change materials slowly begins to
solidify and release the stored latent heat back
into the building. It performs through a natural
passive process continually day after day, year
after year.“

Underground Thermal Energy
Storage; The Principle
 UTES is a system which utilises Interseasonal Heat Transfer (IHT). This involves
the storage of excess energy
 from summer for use in winter heating applications, and the storage of cooling

To keep sand from
blowing into their noses,
camels can shut their
nostrils.
When there is no sand
blowing in the wind, a
camel can open its
nostrils (A) and breathe
through its nose.
When the wind starts to
whip up the sand, the
camel just closes its
nose (B).
http://www.allsinai.info/sites/fauna/camel.ht

 The camel's nose acts as both a humidifier and a
dehumidifier with every breathing cycle.
 The hot, dry air that is inhaled passes over the large area
of moist membrane. This air is immediately humidified by
picking up moisture from the nose and cooled in the
process,. This cooler air passes to the lungs and remains
at approximately body temperature.
 When it is exhaled, it is cooled even further by passing
over the same nasal membranes, this time by a process of
dehumidifying instead of humidifying. The nasal
membranes are coated with a special water-absorbing
substance that extracts the moisture from the air like the
cooling coils of a dehumidifier.
 A net savings of 68 percent in the water usually lost
through respiration occurs just between the cooling and
drying phases of the breathing cycle.

Tenets for Intelligent
Buildings
 Plan and design with an Integrated Team
so that clients, consultants, contractors,
facilities managers all develop a commitment
to the project and want to fulfil the
environmental, social and economic aims.
 Systems and holistic thinking
are key.

 Assess the impacts of the buildings on
occupants and communities nearby.
 Occupants behaviour has a large effect
on the consumption of energy and water
so try to increase awareness of occupants
to the impact of their actions on
resources.

 Aim to increase the built asset value
for the organisation
 Understand users perceptions:
understand the physical and psychological
well-being.
 Design for Flexible and agile space
 Provide Individual control of
environmental conditions

 Use smart metering but wireless
sensor technology becoming applicable
in building operation for personal use by con
sumers.
 Develop data management systems
to give feedback on the performance of
spaces in the building.
 Understand the interaction between the
building, systems and the occupants
 Commission pre-occupancy and post-
occupancy evaluation are vital.

 Use a whole life value approach to
ensure quality and whole life costs consid
ered.
 Aim for simplicity rather than complexity in
operation.
 Think about well-being and freshness
besides comfort and
 consider all the senses and how air, view,
daylight, sound, colour ,greenery and space
affect us in the workplace.

Connectivity is important for
 Interoperability not only between the
systems and the building but also between
the occupant and the building
 Design for flexibility and adaptability

 Think of an Intelligent Building as an
organism responding to human and environmental
needs but also one that needs to “breathe”
through the facade between the external and
internal environments.
 The façade transfers light, solar radiation, air, noise,
and moisture but also links occupants to
the outside world so intelligent or smart facades
allow these aspects to be controlled in a way
which is functional but also
 Design environment to be enjoyable
to those working and living inside the building.

 Balance efficiency with effectiveness.
An air supply system for example can deliver
the “right” amount of air to a space and
be deemed efficient but
may not be effective in the space because it
has no impact on the breathing zone
where the people are.
 Plan facilities management so the building
is cared for

 Design beyond the expectations
defined in Regulations.
 Keep abreast of relevant fields of
knowledge and innovation.
 Learn from other sectors and disciplines
 Develop an integrated approach to education
to meet sustainable agenda

FUTURES
 Carbon negative buildings like artificial leaf
hydrogen generating facades also
 algae biofuel facades
 Green living facades
 Applications of biomimetics
 Smart materials for reactive
facades;embedded sensors, nanotubes ,
graphene
 Application of nanotechnologies
 Robotics for prefabrication, cleaning,
maintenance and site assembly

FUTURES
 Robotics for prefabrication, cleaning,
maintenance and site assembly
 Fully integrated interoperable systems
 Buildings into smart grid system
 Wireless Sensor Technology linking
climate, building, systems and occupants
 Innovation with respect for passive low
technology
 New culture of value, systems and holistic
thinking and vision
