IFC ECO-CITIES PROGRAM

Under the EU-India Cooperation on Clean Technologies And Energy Efficiency

SEPTEMBER 22, 2017

Impact assessment of construction materials

- a key to delivering Green Buildings in India

WHY IFC FOCUS ON CITIES AND BUILDINGS?

• India on brink of urban revolution; will add

another 300 million city dwellers in next 25

to 30 years

• Cities are key for development and job

growth but energy, water, and

environmental problems manifest at the city

level

• Majority of buildings that will exist in India in

2030 have yet to be built

• Buildings contribute to 40% of global energy

consumption, 12% of freshwater use, and

generate 40% of total volume of waste

Climate smart infrastructure and green building interventions are

critical for urban sustainable development in India

“We would like lower

utility bills, but there

aren’t any efficient

homes.”

“We would build for

energy-efficient

homes, but investors

won’t finance them.”

“We would fund

efficient buildings, but

there is no demand for

them.”

Despite a policy push, the complex construction value-chain is

hindering growth of the market – comprehensive approaches

are reqd.

There are many players and the divergence of interests and asymmetry of information

WHY ARE MATERIALS IMPORTANT?

12

In addition to contributing to the durability, strength, longevity of a building- materials

directly contribute to the embodied energy of the building.

Embodied energy

Operational energy

Life cycle energy consumption

20-50 %

50-80 %

13

Embodied Energy (EE)

Extraction of raw materials

Transportation of raw

materials

Manufacturing of building materials

Transportation of finished products

Global warming potential (GWP)

Importance

Embodied energy contributes to about 20-50% of

the total life cycle energy consumption.

�GWP is a measure of the effect on climate

change resulting from emissions of greenhouse

gases.

�For building materials and components GWP

is measured in the equivalent reference unit of kgCO₂.

IMPORTANCE OF EMBODIED ENERGY AND GLOBAL WARMING

POTENTIAL

Importance

Construction materials are produced by industrial

processes that release green house gases into

the atmosphere and GWP is an important

indicator to assess this impact.

Greenhouse gas emissions Climate change

14

For a comprehensive evaluation of a building’s performance,

both embodied energy and operational energy should be

considered.

INDIAN CONSTRUCTION MATERIAL DATABASE

Need

Absence of a database which considers embodied energy

values of Indian construction materials.

Quantification of embodied energy is a cumbersome process,

with no readily available data.

Importance of looking at the regional context of materials.

reference

The database includes a comprehensive set of 96 materials used in Indian

construction projects--structural elements (roof, walls, and floors), insulation,

windows, flooring, and surface treatments.

- Embodied Energy (MJ)

- Global warming potential (kg CO₂ eq)

GaBi software- Life cycle assessment software

“Cradle to gate”, i.e., manufacturing and transport in the supply chain.

- Time reference- use of most recent primary data available

- Technology reference- use of mix of technologies relevant to India

- Geographical reference- Indian context for most products.
