Building Green

CPWD’s Green Vision for the Future

by

Pradeep Kr. Gupta

Additional Director General

CPWD

PM’s NAPFCC

The Prime Minister’s Action Plan for Climate change came out

with a “Mission for Sustainable Habitat” – June, 2008

As part of this work, the Govt. took up initiatives in

- Environmental friendly and Energy Efficient Building

- Solid Waste Management

- Green Transport

GoI’s Mandate

The Ministry of Power (MoP) has brought out the ‘Energy Conservation

Building Code’ in 2007 to provide benchmarks for Energy Efficiency in

Buildings

The Ministry of Environment & Forests (MoEF) brought out

Environmental Guidelines for Large Building Projects

The Ministry of Non Conventional and Renewable Energy (MNRE) &

the Indian Green Building Council (IGBC) have brought out Voluntary

Green Rating Systems for Buildings targeting both Energy Efficiency &

Environmental Performance from Buildings

CPWD’s Mandate

•Way back in 1993 CPWD suo-moto banned use of Solid Timber in

projects for sustainability of Forests

• The Central Public Works Department (CPWD) under the Ministry of Urban

Development (MoUD) has taken up a mandate to construct eco-friendly buildings in

August, 2004.

• The Directorate General, CPWD has issued guide lines in March, 2009 regarding

Green Building Parameters which have been incorporated in CPWD Works Manual

2010.

•The President of India also suggested in 2004 that CPWD shall Focus on 10

missions pertaining to planning, designing and constructing eco-friendly buildings.

“Not just Green from a conventional sense, but making our landmark

buildings push the envelope”

For e.g.

- Indira Paryavaran Bhawan will be a Net Zero Building

- It will also be a Zero Discharge Building

Vision

- CPWD's Officer's Training Institute is mandated as centre for Excellence on Green

Buildings by MNRE.

Capacity Building for Green

Capacity Building for Green

• All our Architect's & Engineering teams across the country are

undertaking

training on Green Buildings, Organizing Regular interactions through

Seminars, Site Visits to prominent Green Buildings, Exhibitions.

• Working to avoid a Green Retrofit Situation by bringing this concept at the

project initiation itself.

• Regular training Programs for DDA, NDMC, ITBP, BIS & other govt. orgs.

• Pvt. Professionals can also participate in the training programmes.

"Very rarely in any country, 150

years of cumulative experience

in design, architecture and

building has been recorded by

a single organisation. CPWD

will be the only organisation

that would have built buildings

and roads in green fields, in

valleys, in deserts, in plains, in

mountains, in sea coasts and in

islands.”

Office Buildings

• Trombe wall uses Solar Energy for warming up the inside portion of rooms adopted in various

buildings constructed at Leh.

• During night time covers are closed to keep heat inside the building thus maintaining higher

temperature and provides comfort to occupants.

• Concept of Solarium or sun spaces was also used effectively.

Environmentally Responsive Building at CPWD

The concept of Environmentally Responsive Building was considered by CPWD

25 years back in the various buildings constructed at Leh, J&K State and others

Admn Block for ITBP, Leh, J&K

CPWD has been attempting to incorporates elements from the traditional architecture of

the region + elements for climatic comfort in a region. For e.g. Trombe walls in the

elevation above

Cold Zone

Indira Paryavaran Bhawan, New Delhi

The Project tries to create a new paradigm in Govt. Office buildings by working with

the local climate in the most optimum fashion to create a Net Zero energy building, a

first in the area of tight urban building blocks.

The concept uses earth as a heat sink for

cooling in summer and as a heat source during

winters. This is possible due to the fairly

comfortable temperature at a depth of about 5 m

below the earth’s surface.

Planning Features

• Less Ground coverage achieved by

planning multistoried buildings.

• Existing natural features & topography

has been maintained.

• Solar panels used for street lighting and

for part lighting for other buildings.

• Solar water heaters to be used in the

Hostels.


Rainwater Harvesting Tank at Fagu, Kufri, H.PCold Zone

Rainwater harvesting has been implemented at a large scale for a campus for

agricultural research (CPRS) in 2009

Water deficient Area initially. A RWH reservoir of 45m x 30m x depth 2.5 m (15.5 lac litre capacity,

Cost 32.6 lacs @ Rs.2/ litre) Incidentally, this is also becoming a tourist attraction locally.

Challenges in Universalizing Green Construction

New materials in SOR helping in the countrywide green effort

- 2010 Schedule of Rates included a range of green materials for e.g.

AAC, Flyash Blocks, FAL-G, Coir Veneer Board, Pressed Clay tile, Mud Mortar

- A new edition to be brought in Jan’2012 will include new material for e.g Bamboo

composite boards, Waterless Urinals, Low VOC Paints, Flyash based Paver blocks

and Concrete Mixes with flyash, Roof Insulations like PUF, Sensor fittings, High Solar

Reflective Index roofing tiles

- Procedure for including new materials includes

• Making a submission with all technical literature before CPWD

• Examination by CPWD committee & approval for a limited period of 2-3 yrs

• Final approval after feedback received from field units

CPWD Schedule of Rates

Change the way of working in Governmental Buildings

- IPB mandated 260 C / 190 C (summer/winter) as the setpoint

temperature providing a message for appropriate clothing.

- IPB's staff will share computing power (Thin Client Systems)

greatly reducing energy requirement.

- IPB will follow Green Housekeeping practices (as also

mandated under the rating systems)

Behavioral Issues Quality of Life

QoL for Construction workers

CPWD implementing Safe construction practices, Adequate & hygienic

Worker’s facilities at all their sites across the country.

QoL for Neighbours

Sensitive to neighbour’s demands for noise control even during day. IPB

decided to get its RMC ready from the factory for this purpose.

Cutting down of trees minimized even further from those approved,

despite minimal construction space

Adopting Best Green Practices

Due to high Groundwater table, large dewatering exercise turned into an

opportunity for recharge in the surrounding area.

35 Lacs Litres per day of water recharged at 2 spots within 250 m of the site

Large amounts of water given for horticultural usages to NDMC

Best Practice Universalizing Renewable Energy

Not as an addon, but as central

to the energy requirements of

the building

The Road ahead is via the solar

highway

Transparency

Transparent process with building approvals, construction

updates, State of onsite trees and those transplanted.
