The document discusses passive solar buildings, which are designed to harness solar energy for heating and cooling. Passive solar buildings utilize elements like southern windows, shading, and thermal mass materials to collect, store, and distribute solar heat in winter and reject it in summer without mechanical systems. There are three main categories of passive solar systems: direct gain, indirect gain, and isolated gain. Passive solar building provide benefits like lower energy costs, increased comfort, and harnessing a renewable resource without bills.

3.  IT AS AN INTRODUCTION TO PRINCIPLES AND
CONCEPT OF UNDERLYING OF BUILDINGS TO
PASSIVELY UTILIZE SOLAR ENERGY FOR HEATING.
 35 TO 40% OF OUR ENERGY IS CONSUMED BY
BUILDINGS AND 85% OF THAT IS NEEDED FOR
HEATING.
 THIS IS AN INTRODUCTION TO THE PASSIVE SOLAR
TECHNOLOGY THAT MAY BE USED TO HEAT
BUILDINGS.

4. “In PASSIVE SOLAR BUILDINGS ,windows,
walls, and floors are made to collect, store
and distribute ‘SOLAR ENERGY’ in the form
heat in the winter and reject solar heat in
the summer.
WHAT ARE PASSIVE SOLAR BUILDINGS?
REVA UNIVERSITY 4

5. Passive solar buildings are designed to let heat into the
buildings during the winter months and block out the
sun during hot summer days. This can be achieved by
passive solar design elements such as shading ,
implementing large south facing windows ,and building
materials that absorb and slowly release the sun’s heat
HOW DOES IT WORK?
REVA UNIVERSITY 5

6. THERE ARE THREE TYPES OF SYSTEMS/CATEGORIES
ARE AS FOLLOWS:
 DIRECT GAIN SYSTEM.
 INDIRECT GAIN SYSTEM.
 ISOLATED GAIN SYSTEM.
CATEGORIES OF PASSIVE SOLAR ENERGY
/SYSTEMS
REVA UNIVERSITY 6

7. DIRECT GAIN SYSTEM
Direct gain method is the
simplest method where
the space of the building is
directly heated by sunlight
REVA UNIVERSITY 7

8. INDIRECT GAIN SYSTEM
For indirect gain, sunlight
is often received by a
south facing wall , and as
air moves internal space
the heat moves through
the living room.

9. ISOLATED GAIN SYSTEM
Isolated gain method
contains solar collection,
thermal storage that are
separated from actual living
space.

11.  Mainly it provide perfect temperature and it is
renewable energy resource.
 It’s cost of installation is lower than active solar
energy resources.
 Less or zero usage of conventional equipment.
 Harness the power of sunlight.
 No bills and many more……

13. PASSIVE SOLAR BUILDINGS IN INDIA
It’s India’s first net zero energy building
that has been constructed with adoption
of solar passive design and energy-
efficient building materials- NEW DELHI

14.  Bright interiors and transmits visible light.
 Cooler and comfortable in summer.
 Warmer in winter.
 Blocks ultraviolet energy.
 Saves the money rather than wasting for cooling and
heating bills.
BENEFITS OF PASSIVE SOLAR BUILDINGS
REVA UNIVERSITY 14

15. They can perform effortlessly and quietly with out
mechanical or electrical assistance.
Reduction can be made to heating bills by as much as
40% annually, and also improve the comfort of living
spaces.
Simple techniques can make a huge difference in the
comfort and energy consumption through year.
