This document provides information about the PEDA Office Complex in Chandigarh, India. The complex was designed using solar passive architecture and features elements like light vaults, a wind tower coupled with solar chimneys, and a unique floating slab system to maximize natural ventilation and passive cooling. It has an orientation and shell roofing structure over the central atrium that help minimize solar gain in the summer and maximize it in the winter. The complex serves as a successful model for energy efficient and sustainable building design appropriate for Chandigarh's composite climate.

GEOGRAPHY
Context & Site microclimatic analysis
Architectural building design needs to respond to the composite climate context of the site.
The final design solution needs to satisfy the diverse and often conflicting conditions of a
hot-dry, hot-humid, temperate and cold period of Chandigarh.

8. The Climatic conditions
 Two months of hot & dry
 Hot-humid (two months) and
 Cold period (two months)
 Occasional hazy in summer & high in monsoons
cold winds in winter and strong wind in
monsoons.
Require strategies of design
 Cooling in the hot dry period.
 Natural ventilation in the hot-humid period
and
 Heating in the cold period.
 Cooling remains as the predominant
requirement since the total over heated
period extends from mid-april to mid-august.

9.  Building : PEDA Office Complex
 Architect : Prof Dr. Arvind Krishna
 Architectural Design : Sustainable Architecture
 The building has a 3 Dimensional form responding to solar
geometry. i.e., minimizing soil heat gain in hot dry period
and maximizing solar heat gain in cold period.
 Overlapping floors at different levels in space floating in a
large volume of air, with interpenetrating large vertical
cut-outs enclosed within an envelope. These are
integrated with light wells and solar activated naturally
ventilating, domical structures.

10.  Daylight
 On the south western facade, dome shaped concrete
structures have horizontal and vertical intersecting
fins with glass fixed in the voids to allow natural light
with reduced glare.
 These allow indirect light to enter the building in
summers and direct sunlight in winters.
 The atrium is covered by a lightweight shell roofing
of 10 cm of high-density EPS (extracted polystyrene)
sandwiched between high-grade FRP (fibre-reinforced
plastic) sheets and reinforced with steel; specially
angled to allow sun in winters and block in summers.

11.  Maintaining thermal comfort
 The envelope attenuates the outside ambient conditions and
the large volume of air is naturally conditioned by
controlling solar access in response to the climate swings
during summer and winters.
 The large volume of air is cooled during the hot period by a
wind tower, integrated into the building design, and in cold
period this volume of air is heated by solar penetration
through the roof glazing generating a convective loop.
 The thermal mass of the floor slabs helps attenuate the
diurnals swings.

20.  Evaporation cooling towers work best with open floor plans that permit the
air to circulate through out the buildings without any obstacles.
 Good thermal mass of the building helps the building to perform in extreme
conditions. Appropriate building design and orientation having properly
placed building elements reduced or minimize the solar gain in summer.
 Elements like light Vault, Solar chimney, Hyperbolic parabolised atrium roof
help to minimize the solar gain.
