    Study Notes

    Building Design

    • South-facing facades benefit from deciduous trees, overhangs, or louvers.
    • East and west facades can be protected with vertical louvers.

    Renewable Energy Types

    • Renewable energy is a naturally occurring, inexhaustible energy source that is derived from non-fossil and non-nuclear fuels.
    • Examples include solar, wind, tidal, hydroelectric, biomass, and geothermal.

    Solar Energy

    • Passive solar energy directly captures the sun's warmth and light through building design.
    • Active solar energy uses technology to transform sunlight into electricity.

    Wind Energy

    • Wind energy uses the kinetic energy of air to generate electricity.
    • Wind turbines or wind energy conversion systems transform wind energy into electricity.
    • Wind energy is a rapidly growing energy source and has been used for hundreds of years.

    Hydroelectric Energy

    • Hydroelectric energy utilizes the flow of moving water to generate electricity.
    • This method is one of the oldest and largest renewable energy sources.
    • A dam stores water in a reservoir, which is released through a turbine to generate electricity.

    Biomass (Biofuel) Energy

    • Biomass energy uses plant-based material as fuel to generate heat or electricity.
    • Examples include wood, agricultural residues, and waste from industries and households.

    Foundation Materials

    • Four common foundation materials include cast-in-place concrete, concrete block, preserved and treated wood, and insulated concrete forms (ICF).
    • The thickness of each material varies depending on the depth of the wall below grade.

    Foundation Walls

    • Foundation walls can be laterally supported or unsupported.
    • A laterally supported wall has a floor system secured to its top, preventing it from collapsing inward.
    • An unsupported wall does not have a floor system secured to it.

    Formwork

    • Formwork is the mold used for pouring fresh concrete that shapes it until it cures.
    • Formwork can be permanent or temporary.
    • Metal tie bars are used to keep the formwork sides from separating.
    • Formwork should remain in place for at least three days for proper curing.

    Insulated Concrete Formwork (ICF)

    • ICFs create cast-in-place concrete walls sandwiched between layers of insulation, usually polystyrene foam.
    • ICFs remain permanently in place, providing both formwork and insulation.
    • They reduce labor costs and are energy efficient.

    Cast-in-Place Concrete Foundation Walls

    • Cast-in-Place concrete is poured into the formwork and cured on-site.
    • The concrete should be vibrated during placement to remove air pockets.
    • Concrete should be poured continuously to avoid segregation.

    Engineered Wood Products (EWP)

    • EWP includes various manufactured wood products made by binding or fixing wood strands, particles, fibers, or veneers together using adhesives or other methods.

    Floor Framing Spans

    • Beam span is the distance between the supported ends of a beam.
    • Supported joist length is half the span of the floor joist on either side of the beam combined.
    • Joist span is the clear distance between the two supporting ends of a joist.

    Required Information for Beam Calculations

    • Number of floors
    • Beam span
    • Supported joist length (SJL)
    • Lumber type

    Required Information for Floor Joist Calculations

    • Joist span
    • Lumber species or type of joist
    • Joist spacing
    • Type of bridging

    Dead Load

    • Dead load consists of the weight of the joists, materials above the joists, and permanent equipment in the building.
    • It is typically calculated at 20 psf (pounds per square foot) or 1 kPa (kilopascal).
