This document discusses passive heating systems for buildings. It describes how 35-40% of energy is used for building heating and 85% of that is for space heating alone. Passive heating technologies are introduced that can heat buildings without energy usage through building design. Direct solar gain and Trombe walls are passive solar systems explained in detail. Trombe walls consist of a dark wall with glazing in front to capture solar heat. Design plans, elevations, sections and details of a sample building project using a Trombe wall system are presented, showing how passive heating is integrated into the design. The conclusion states that passive heating can significantly reduce heating bills and improve comfort through simple techniques.

2. Introdiction
Industrial and technological innovations, population
growth, and rapid urbanization lead to an increase in
energy consumption.
Dependency on foreign sources of energy and their
negative environmental impact have made energy efficiency
and conservation critical issues.
35–40% of our energy is consumed by buildings, and
85% of that is need solely for heating.

3. Passive Heating
Refers to technologies or
design features used to heat
buildings without power
consumption.
Building design attempts to
integrate the principles of
physics into building exterior
envelope to:
Speed up heat transfer into
a building

4. Direct Sun Gain System
Direct Solar
Gain Direct gain is
the heat from the sun
being collected and
contained in an
occupied space. Direct
solar gain is
important for any site
that needs heating,
because it is the
simplest and least
costly way of
passively heating a
building with the sun.
Avoiding direct solar
gain is also important
in hot sunny climates.

5. Trombe Wall
A Trombe wall is a system
for indirect solar heat gain
that is a good example of
thermal mass, solar gain,
and glazing properties used
together to achieve human
comfort goals passively. It
consists of a dark colored
wall of high thermal mass
facing the sun, with glazing
spaced in front to leave a
small air space.

6. Trombe Wall
In summer
•The density of the materials in the Trombe wall acts as a
method of slow heat absorption and transfer.
In winter
•In the winter, when the sun is allowed to shine on them,
they can be ‘charged’ up to help to warm the house by
transferring the sun’s heat inside.
•In the winter, when the surrounding outside air
temperature drops as the air cools after the sun has gone
down, the object with thermal mass will continue to
release its stored heat energy.
•When all the heat is discharged, it is ready to once
again ‘charge’ up or absorb heat again.

10. Stone Storage System
•Concrete block buildings are very common they may offer
opportunities for passive solar retrofits.
•Concrete floor slabs and massive partitions between zones
help prevent overheating and otherwise improve the
performance of concrete block thermal storage walls
•For new construction, superior performance of solid
masonry walls by filling the cores of the block in the
thermal storage wall with mortar as it is erected.

11. Design
The design was first created on a
natural site with a 70 m2 plan. this
plan is rectangular. The terrace was
designed using sloping terrain. There
are 2 floors: ground floor and
mezzaine floor. It uses a glass
thrombed wall system that closes them
with the openings on the facades.
There is a solar energy system.
In addition, energy can be saved by
using sunlight. trombe wall consists
of dark concrete and the aim is to
absorb the sunlight better. The reason
why it is a bigger facade compared to
the front facade is to benefit from
the maximum degree of sunlight.

31. Conclusion
•They can perform effortlessly and quietly without
mechanical or electrical assistance.
•Reductions 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 the years.
•The economical solution to a warmer house in the winter
and a cooler house in the summer is to insulate it well,
while understanding the movement of heat. it is the
better solution.
