Table 1.1: Sources of pollution along with mitigation measures
Project : Ashiana Dwarka Form-1A
Promoted by : Ashiana Housing Ltd.
Source Impact Mitigation
Various sources of pollution during construction with their impact on existing environment and mitigation
are listed below:
AIR QUALITY :
• Uncovered
stockpile
• Construction
activities like
Cutting,
grinding,
sawing and
scrabbling.
• Chutes and
skips.
• Cause
environmental
degradation,
including air and
water pollution.
• Create problems
with visibility.
• Damage or dirty
property and
belongings.
• Create unsafe
working
conditions.
• Erect solid screens or barriers around dusty activities or the
site boundary that are at least as high as any stockpiles on
site.
• Water spraying to prevent dust pollution from different
sources of construction.
• Earthworks will be covered temporarily.
• Predominant wind direction will be considered for siting
stockpiles.
• Stockpiles will exist for the shortest possible time.
• Stockpiles will be enclosed or securely sheeted.
• Pre fabricated materials like RMC will be used for
construction.
• Covering the construction site on all four sides to a
considerable height to prevent dust emission and other
pollutant to the surrounding environment.
CONSTRUCTION PERIOD NOISE AND VIBRATION :
• Construction
equipments and
traffic noise.
• Construction
noise is
unavoidable and
could adversely
affect during
construction
activity periods.
However, the
impact would be
temporary and
limited to the
time of the
construction in
any location.
• All construction equipment would be required to conform to
the Standard Specifications to minimize noise from
construction activities, such as maintaining equipment
mufflers in proper operating order.
• The contractor will be required to comply with local noise
control ordinances, to the extent practicable.
• Construction noise barriers, such as temporary sheet walls or
piles of excavated material between noisy activities and noise
sensitive receivers.
• Combine noisy operations to occur in the same time period.
The total noise level produced will not be significantly greater
than the level produced if the operation were performed
separately.

account the increased traffic
generation as a result of the
proposed constructions)
: The construction of buildings has a very important impact
on the environment, and the process of manufacturing
and transporting of building materials, and installing and
constructing of buildings consumes great energy and
emits large quantity of greenhouse gas (GHG).
However an assessment based on one of the research
paper estimates the GHG emission 82–87% of the total
GHG emissions are from the embodied GHG emissions
of building materials, 6–8% are from the transportation of
building materials, and 6–9% are due to the energy
consumption of construction equipment. The results also
indicate that embodied GHG emissions of concrete and
reinforced steel account for 94–95%
(Source: Greenhouse gas emissions in building construction: A
case study of One Peking in Hong Kong, Hui Yana, Qiping

much energy saving has been
effected?
: Walls.
East and West Elevations.
Walls that face the east and west will be well insulated as
possible, to prevent summer heat gain. Use of PPC
cement having fly-ash content and higher reflectance (as
compared to OPC cement) will be used.
Following additional measures are suggested to be used
for maximizing the shading of walls on the East and the
West:
• Very few Openings and high thermal mass to reject
and store the Solar heat on South facing Façade.
Roof:
Roofs will be covered with break tiles.

9.8 What are the likely effects of
the building activity in altering
the micro-climates? Provide a
self-assessment on the likely
impacts of the proposed
construction on creation of
heat island & inversion
effects?

sources:
• Heat absorbed and radiated from the paved and
concrete structures.
• Increased population for a particular stretch of land.
The building materials will be selected with
characteristics that limit heat ingress into the inside of the
building will be minimized.
Any building activity would alter the microclimate of a site
and it is inevitable that wind patterns and thermal-gain
patterns on a site would be changed. But the proposed
building has been carefully designed to modify the
microclimate so as to improve overall thermal comfort
and reduce energy consumption.
Shade giving trees will be planted near the east and west
side which affect the microclimate and provide cooling
effect in summers.
