The
government
of
Thailand
legislated
an
Energy
Conservation
Promotion
Act
(ECP
Act)
in
1992
and
set
bye-laws
that
identify
designated
buildings
(DBs)
and
detail
mandatory
requirements
for
energy
conservation
for
DBs
in
1995.
An
Energy
Conservation
Promotion
Fund
(ENCON
Fund)
was
also
created
to
fund
energy
audits
on
1900
DBs.
Recently
the
requirements
and
procedures
for
energy
conservation
in
buildings
have
been
revised
where
system
performance
requirements
for
building
envelope,
lighting,
air-
conditioning,
and
hot
water
generation
are
adopted.
Moreover,
the
new
building
energy
code
(BEC)
distinguishes
different
categories
of
DBs,
provides
credit
for
use
of
solar
energy,
and
introduces
a
new
option
of
whole
building
energy
compliance.
The
authors
develop
building
models
from
data
obtained
from
energy
audit
reports
and
use
them
to
estimate
savings
on
energy
and
peak
demand
from
future
new
buildings
using
forecasted
energy
and
peak
demand
data
from
the
Load
Forecast
Subcommittee,
a
panel
tasked
to
forecast
future
electric
load
of
Thailand.
From
a
modest
level
of
energy
saving
in
the
first
year
that
the
code
is
expected
to
be
enforced,
the
level
of
saving
rise
to
over
10%
and
20%
annually
of
requirement
of
target
buildings
in
6
and
12
years
respectively.

Introduction
Thailand
was
a
net
energy
importing
country
ever
since
it
began
its
first
Economic
and
Social
Development
Plan
to
embark
on
a
new
phase
of
coordinated
economic
development
in
1964.
From
1985
to
the
present,
per
capita
consumption
of
oil
and
natural
gas
has
increased
six
folds,
while
per
capita
consumption
of
electricity
has
increased
five
folds
[1,2].
