Each material, whether it forms anidentifiable element or component of theconstruction or part of the internal fabric, hasits own characteristic and requirements.

Differences between Traditional building andModern Building ?

Needs of The Building Users

The use and function of buildings changeover time, and with each change comes adifferent, often conflicting, set of

requirements. These user requirements will typically leave

evidence in the form of physical changes tothe structure, fabric and services of the

building; personal recollections andremembrances; and associateddocumentation

Perceptions of Building

These personal, and often intimate,perceptions and sensations may includethe following;

Light and dark Hot and cold Dry and humid Sunshine and shadow Colour and texture Smells and odours (e.g musty cellar)

Sound and silence (e.g music) Location and situation Size and scale Context and use Character and association (e.g haunted house)

Feelings that might be experienced when inand around buildings may thus indicate a latentawareness of what is good and bad.

Good feelings Bad feelings

Homely Peaceful Spiritual Restful Atmospheric Inspiring

Welcoming Comfortable Spacious Uplifting Exciting Breathtaking

Claustrophobic Intimidating Overwhelming Demoralising Cramped Oppressive

Lonely Morbid Isolated Uncomfortabl

e Impoverished Squalid

Requirements of buildings

In order to be successful, the design andconstruction of a building has to considera variety issues

These may be considered as being:

Functional requirements Performance requirements

Statutory requirements User requirements


9/30

Functional Requirement

Every building, regardless of its original,intermediate or ultimate use, can beexpected to fulfil certain basic

functional requirements. These requirements are primarily

concerned with protection from theexternal environment, human

comfort, and organisation of activityand space.


10/30

Performance requirements

For a building to be successful, it mustsatisfy the basic functional requirements.

The way in which it meets these demands,

both as a building and as a collection ofrelated and interrelated parts, may bedetermined by how it performs in relationto a number of defined performancemeasures or standards.

Statutory Requirements

There are various statutory and non-statutory requirements that makedemands on those who design, build,

manage repair, maintain, occupy ordemolish buildings. In practice, many ofthese demands are made in relation to thehealth, safety and well-being of such

persons.


14/30

User Requirements

The user of a building can expect to live or workin a space that satisfies basic humanrequirements and, in addition, certain needsthat are specific to the activities being performed.

To identify purpose in terms ofactivities (thethings people do) and human needs (physical,psychological, physiological and social).

Building to be fit for its purpose it must allow

its occupants to carry out their activitieseconomically and conveniently, and have asatisfactory environment to suit the user

Conclusion

The various aspects of design andconstruction that will have influencedhow it was built and how it hasperformed

Consideration of functional, performance,statutory and user requirements, willprovide much information to be assess

but there are other level investigationthat also need to considered.
