Week 02 Summary

Construction Systems Enclosure System – protection, shell or envelope of a building, consisting of the roof, exterior walls, windows and doors. (Ching, 2014) Service System – anything providing amenity/essential services to the building; electrical, mechanical, hydraulics. Structural Systems – frame, column & beam, mass construction.

ESD Strategies ESD – Environmental Sustainable Design Recyclability – reduce, reuse, recycle. 1. Carbon footprint – measure of greenhouse 2. Gases used. 3. Local materials 4. Thermal mass – use of a material to store energy, e.g. concrete slab. 5. Water harvesting – collection and use of rainwater. 6. Insulation 7. Wind energy 8. Solar power 9. Material efficiency 10. Night air purging – bring outside air inside in the evening to remove stable air. (Newton, Clare, 2014)

Structural Joints Roller Joint – allows horizontal movement; only resists vertical forces. Pin Joint – allows rotation, resists both vertical and horizontal.

Structural Systems Every load must have a responding force of equal strength. Solid Structure – early buildings; mud, bricks, stone; Compression architectures, efficient, e.g. Egypt, Great Wall. Surface Structure – Sydney Opera House Membrane Structure – tension, shade sails, sport stadiums; large area; Cheap. Hybrid Structure – air integral; particular membrane called ETFE; covering large, expense economically, quickly, e.g. Beijing Olympic swimming cube and bird nest. Skeletal Structure – common; frame system; very efficient way to transfer loads down through to the ground. (Newton, Clare, Structural Systems and Forms, 14/03/2014) Consideration

Performance requirements – structural, fire resistance, comfort, protection from elements, compatibility, easy maintenance. Aesthetic qualities – proportion, color, surface qualities. Economic efficiencies – budget, affordability(initial cost & maintain cost). Environmental impacts – embodied energy, constructability efficiency. *EMBODIED ENERGY – how much energy is in the item. Moving it, maintaining it, running it, getting rid of it.

Fixed Joint – Resists vertical, horizontal and rotational forces. (Cantilever – one point of support, e.g. a tree, wing of a plane)
