Design of the terrain of The Park in Riem
In order to be accountable to the human scale, despite the almost geographical dimensions of the park, the landscape architect undertook several decisive changes in topography.
Design philosophy of The Park in Riem
The design by French architect Gilles Vexlard won
the first prize within the 1995 international design
history of The Park in Riem Germania
With a population of one 1.3 million folks,
Munichis the third largest town in Germany.
The new space around the metropolis
Exhibition Centre is presently being developed
as a replacement town quarter.
THERMAL STORAGE WALL SIZE
Correct wall size varies with native conditions
and climate; the number of insulation used; and
also the latitude of the vacant lot. the primary 2
parts have an effect on the speed of temperature
loss from an area, that is influenced by the number

Passive solar energy
Advocates of passive solar design have been
around for many decades and the prize-winning
schemes in a European competition for passive
Sound and vibrations in architecture
Sound is a vibration in an elastic medium such
as air, water, most building materials, and the earth.
(Noise can be defined as unwanted sound, that is,
annoying sound made by others or very loud sound
which may cause hearing loss.)
An elastic medium returns to its normal state after a
force is removed.
Pressure is a force per unit area. Sound energy progresses
rapidly,producing extremely small changes in atmospheric
pressure, and can travel great distances.
However, each vibrating particle moves only an infinitesimal
amount to either side of its normal position.
It “bumps’’ adjacent particles and imparts most of its motion
and energy to them.A full circuit by a displaced particle is called
a cycle. The time required for one complete cycle is called the
period and the number of complete cycles per second is
the frequency of vibration.
Consequently, the reciprocal of frequency is the period.
Frequency is measured in cycles per second, the unit for
which is called the hertz (abbreviated Hz).
A pure tone is vibration produced at a single frequency.
depicts the variation in pressure caused by striking a tuning
fork, which produces an almost pure tone by vibrating
adjacent air molecules.
Symphonic music consists of numerous tones at different
frequencies and pressures (that is, a tone is composed of a
fundamental frequency with multiples of the fundamental,
called harmonics).
theprongs of the tuning fork alternately compress and
rarefy adjacent air particles. This cyclical motion causes a
chain reaction between adjacent air particles so that the
waves (but not the air particles) propagate away from the tuning fork.
The dangers of drawings
Of course the ‘greater perceptual span’ of design
by drawing as opposed to vernacular design enabled
greater rates of experimentation and thereforeincreased
the risk of failure.
