This Course for Diploma in Textile Engineering , Garments Design & Pattern Making

Subject Aims:

• Describe Weather and Climate.
• Describe the climate effects on human shelter.
• Describe the biological approach in building design.
• Memorize the aspects of solar energy and wind direction in building design.
• Describe the aspect of topography and contour.
• Describe the effects of prevailing winds on building.

• Describe the relation between environment and building forms.
• Describe the thermal effect of materials.
• Describe the treatment for climate effect on building.

Subject Outcome:

Climatology in architecture is a study related to the climate and the built environment. Buildings do not exist in isolation; they exist in a specific geographic environment. As a specific discipline, architecture strives to ensure the harmony and unity of architecture and the surrounding geographic environment. A climate rationale provides the specific underpinning for evidence-based climate decision making. It ensures that the linkages between climate impacts, climate action and societal benefits is fully grounded in the best available climate data and science. Climate plays a very important role in architecture and building forms. The composition of climatic data and the requirements for thermal comfort provides the basis for the selection of building form and building elements appropriate for the climate so as to create necessary internal comfort. One of the main factors contributing to climate change is architecture. The sector is accountable for about 50% of the greenhouse emissions in the country due to construction as well as the energy needed to keep buildings operational.

Diploma in Engineering Level students are required to acquire the knowledge
and skill on concept of nature of electricity, electrical house wiring, Earthing
and Electrical wiring tests. By the completion of this course student will be
able to perform different types of joints and splices, Fittings of electrical
installation works such as lamp circuit, Tube light circuit and Calling bell
circuit. As such the knowledge of basic electricity the pre-requisite for these
fields for effective discharge of their duties. These necessities the
introduction of Electrical Engineering subject in the curriculum of Diploma in
Engineering level. The subject covers only such topics which will enable the
diploma engineers to identify and classify the different types of Hand tools
used in electrical house wiring, Different types of switches, Lamps, Electrical
Fittings and fixtures Conductor, Insulator, Semiconductor, Wires and cables,
Joint and splices. They will be able to verify and apply Ohms law, Joules law,
Series and Parallel circuit. Have been given more emphasis on practical aspect
rather than theory in teaching learning approach.
