Policy Imperatives for
Capacity Building for
Low Carbon Construction and Building Materials
T he
construction sector is an important part of the economy, steadily
contributing about 8 per cent to the national GDP over the last 5 years.
Fuelled by strong economic growth, rising population and rapid
urbanisation, it is one of the fastest growing sectors in India today.
It also provides employment to 18 million people directly1.
The downside is the enormous resource and energy footprint of the
sector. The impact is set to only increase with a housing shortage of
about 40 million houses in the rural spaces alone, for the Twelfth Five
Year Period of 2012-2017. Given the massive growth in new construction
and the inefficiencies of existing building stock worldwide, if nothing
is done, greenhouse gas emissions from buildings are expected to more
than double in the next 20 years. Added to this, the increase in
activity due to reconstruction processes to rehabilitate climate
refugees especially due to freak weather events - and the resource and
carbon footprints of the industry sky rocketed.
As the climate changes there is
a danger that current buildings in terms of design, location, use of
building materials, and technology may not be suitable keeping in mind
various impacts like rising sea levels, increased occurrence of severe
weather events, increasing natural disasters and severe water shortages.
Also, building material choices are important in sustainable design
because of the extensive scope for impacting sustainability by reducing
the embodied energy of the building materials during their extraction,
processing, transportation, utilization, and even thereafter. Building
resilience and adaptability in terms of capacity of a building to
continue to function and operate under acute conditions, such as extreme
temperatures, sea level rises, natural disasters, etc with the optimum
use of available natural resources is a great challenge.
Challenges & Potential for Low Carbon Growth
Attention is now shifting
towards a low carbon climate resilient (LCCR) development that looks at
both mitigation measure against climate change and adaptation measure to
deal with the impacts of the change. United Nations Framework Convention
on Climate Change has identified this sector as being one of the
cheapest avenues for mitigating climate change. As a response to the
global attention on climate change, the Indian Government has taken
steps to initiate a low carbon growth trajectory. The National Mission
for Enhanced Energy Efficiency and National Mission for Sustainable
Habitat propose solutions for buildings and urban infrastructure. A
neglected aspect is climate proofing i.e. adaptation measures in the
habitat sector against natural disasters at planning and design level.
Another lacuna is the lack of attention towards the 70 million
(population) strong rural spaces and small towns which are emerging as
areas of high growth. The Ministries of Rural Development, Panchayati
Raj and Human Resources Development, have articulated the need to
incorporate ‘climate change’ in rural and semi-urban infrastructure
development and reduce the demand for energy and resources required in
the processes. Further, the Ministry of Rural Development intends to
fill the gap in rural housing in an ecologically responsible manner by
requesting state governments to develop region specific construction
techniques.
Thus the policy intent is very
clear. But due to lack of information and research in this field, no
specific actions were taken to reduce or mitigate the damage. However,
there is a lack of customized information and knowledge available on
alternate technologies and their benefits (financial and environmental).
While low carbon climate resilient concepts are proclaimed to have
multiple benefits, there is no method for assessment, quantification and
comparison. Also the huge existing capacity gaps have been a barrier to
address these issues. Technical capacity building is a key gap in the
sector. Discussions with stakeholders reveal that there is a lack of
adequate opportunities available to build and strengthen skills in the
area.
Another very important aspect
is that of creating awareness about low carbon climate resilent
concepts, technologies and tools among all stakeholders especially the
end users. While architects have heard of alternate technologies, most
developers and home builders have not and are unwilling to deviate from
conventional energy and resource intensive technologies. A pull factor
will be created when people demand or accept alternate technologies on
par with conventional ones with respect to quality, costs and
aesthetics.
Policy Imperatives
The movement towards a Low
Carbon, Climate Resilient (LC-CR) development pathway is dependent on
creating an enabling environment focusing on three key factors of
knowledge (building a technology base), finance (devising innovative
mechanisms) and policy (strengthening the institutional framework). Some
policy imperatives for knowledge are :
•
There is a research
need to fill knowledge gaps and customize technologies to local context.
Research on the strength and durability of composite systems as compared
to conventional ones, studies on strength and feasibility of vernacular
technologies with an aim of standardization, research in terms of
monitoring studies, risk analysis, cost comparisons between alternate
and conventional RCC technologies. The next step is communicating this
research to the grassroots.
•
There are design
softwares available in the market that provide some insights into the
process, however there is no consolidated tool to provide a bird’s eye
view that can help in decision making. There is an urgent need to plug
this knowledge gap. Carbon, water and resource footprints can be used as
indicators to aid decision making.
•
Technical trainings
for masons and engineers need to be organised on a regular basis. The
existing network of building centres and technical institutes would be
an ideal place to start technical capacity building. However there is an
urgent need to build capacities of the network to be able to deliver.
Introduction of LC-CR concepts in the technical curriculum will help
shape the new generation of architects and engineers to use these
materials and technologies.
•
Technical institutes
in each district can also function as support cells for local users.
On-site testing tools and training imparted to engineers especially to
test alternate materials and technologies can help build confidence in
them.
•
Creating localized
inventories of technologies & experts who can execute these projects and
existing buildings for exposure were suggested. Similar steps have been
undertaken for energy auditors by the government. All government
buildings and social housing scheme houses should be built using LCCR
principles to build confidence in the technology. Exposure visits to
such buildings will aid. This is important to create a demand for this
type of construction.
•
Capacity building of
media personnel to propagate ideas of LC-CR construction and make people
aware of a low carbon lifestyle. Also, they need to be made aware of the
options available to them, an alternatives to conventional energy
intensive construction techniques.
•
The transition to a
low carbon pathway is not just a function of technology and design. The
key to a successful transition is behaviour change among all
stakeholders especially user communities. Guidelines for use of spaces
should be part of the design process and shared with occupants on a
regular basis.
