ITU-T Study Group 5
• ITU-T Study Group 5 (SG5) is responsible for studies on
methodologies for evaluating ICT effects on climate change and
publishing guidelines for using ICTs in an eco-friendly way.
• SG5 work encompasses globally agreed methodologies for measuring
the carbon footprint of ICTs, to facilitate measurement of the impact of
ICTs on emissions and support meaningful reporting and comparisons.
ITU’s common methodology will help establish the business case to go
green and support informed consumer choices and climate-friendly
business procurement.

What is a Smart
Footer Building 6
Definition
1. Provides actionable information regarding the performance of building
systems and facilities;
2. Proactively monitors and detects errors or deficiencies in building
systems;
3. Integrates systems to an enterprise business level for real-time
reporting and management utilization of operations, energy and occupant
comfort;
4. Incorporates the tools, technologies, resources and practices to
contribute to energy conservation and environmental sustainability.
With smart technology, we can learn anything we want about a building
and optimize its performance.
But real performance means happier, more productive tenants.

Opportunity
Around three quarters of global greenhouse gas emissions come
from cities, and the C40/ Arup Deadline2020 report shows that
building energy use accounts for over half of total city emissions
on average.
This means that decarbonising buildings in cities – by making
them more efficient so they use less energy, and by cleaning up
the energy that they do use – is one of the most fundamental
things that we can do to avoid dangerous climate change

Design and Implementation of Smart Buildings
Integrated Design Process (IDP) allows for the systemic approach, which
optimizes building performance iteratively, and involves all design team
members from the start (Montanya et al., 2009; Pope and Tardiff,)
Savings at the system level are generally larger than for individual devices
(pumps, motors, fans, heaters, chillers, etc.), as are related net
investment-cost savings—usually several times higher (Levine et al.,
2007; Harvey, 2008)

Design and Implementation of Smart Buildings
Essential steps in the design of low-energy buildings are:
(1) building orientation, thermal mass, and shape;
(2) high-performance envelope specification;
(3) maximization of passive features (daylighting, heating, cooling, and ventilation);
(4) efficient systems meeting remaining loads;
(5) highest possible efficiencies and adequate sizing of individual energy-using devices
(6) proper commissioning of systems and devices.
Cost savings can substantially offset additional high-performance envelope and higher-
efficiency equipment costs, of around 35–50% compared to standard practices of new
commercial buildings (or 50–80% with more advanced approaches).
Retrofits can routinely achieve 25–70% savings in total energy use (Levine et al., 2007;
Harvey, 2009).

Energy Performance in Canada
Overall, the Energy Use Intensity (EUI)
for BOMA BEST certified Office
buildings has dropped from 32.8 in 2008
to 27.4 in 2014.
This translates to cost savings of over
$200,000* per year.
*assuming an average electricity cost of $0.15 per kWh/square foot for
a 250,000 square foot building.
