CONSTRUCTING ENVIRONMNETS LOG BOOK- WEEK 2- LEARNING LOOP SYSTEM: “An assembly of interrelated or interdependent parts forming a more complex and unified whole and serving a common purpose” (Ching, 2014) SRUCTURAL SYSTEMS STRUCTURAL SYSTEMS AND FORMS • STRUCTURAL/SKELETAL SYSTEM: Designed and constructed to; support, transmit applied gravity and lateral loads safely to the ground without exceeding the allowable stresses. o The superstructure (vertical extension of a building from its foundations) o Columns, beams and loadbearing walls o Substructure (Foundations) ENCLOSURE/ENVELOPE/SHELL SYSTEM: The shell of the building, consisting of; roof, exterior walls, windows and doors. o Roof and Walls shelter interior spaces from inclement weather, control moisture, heat, and air, dampen nois e, CONSTRUCTING/BUILDING provide security and privacy. SYSTEMS • SERVICE OR MECHANICAL SYSTEM: Provides essential services. o Water for human consumption and sanitation o Sewage disposal o Heating, ventilating and air conditioning systems o Electrical systems, power, lighting, security, communication o Vertical transport systems (Elevator) o Fire fighting systems o Waste disposal and recycling systems
(Ching, 2014) STRUCTURAL JOINTS ROLLER JOINT: Loads transferred only in one direction. As soon as force is applied in any other direction the roller moves. PIN JOINT: Very common, useful in terms of engineering calculations and assumptions about how the structural system might behave FIXED JOINT: Most complex to calculate as bending can occur at the joint
ESD (ENVIRONMENTALLY SUSTAINABLE DESIGN) COMMON ESD STRATEGIES: Local materials, Thermal mass, Material Efficiency, Night air purging, Solar Energy, Wind Energy, Cross Ventilation, Smart Sun Design, Insulation, Water Harvesting REFERENCES

GLOSSARY WEEK 2 STRUCTURAL JOINT: A place were building elements meet and are then joined, how they are joined is contextually dependent. COLUMN: A column is a structural system, designed to support and transmit applied gravity vertically down. TENSION: Pulling apart or stretching of a material. Tension is the subsequent opposite of compression. FRAME: A frame, in construction, is the fitting together of various components to provide structural support.
