Week 8: Mechanical Systems

 Mechanical Systems

  • The U.S. Department of Energy acknowledges the following that are subdivided into renewable and nonrenewable resources
  • Renewable resources
    • solar, wind, water, geothermal and bioenergy
    • these are clean energy sources and are investments being made by the government towards a more secure future with energy
  • Energy Debate
    • The energy debate talks about the usage of fossil fuels vs renewable energy but not knowing if is renewable resources can ever fully replace fossil fuels
  • Sources of fuel
    • bioenergy
    • fossil fuels
    • hydrogen
    • nuclear energy
    • wind power
    • hydrogen
    • solar
    • fusion
  • Natural Gases
    • Fracking uses water, sand, and chemicals to break down rocks to release the natural gases in them, but this waste can damage the local water supply. 


  • Coal
    • Fossil fuel is obtained through underground mining 
    • Coal takes millions of years to form and after it has been used it takes thousands and millions of years to form more
    • Coal is associated with pollution such as mercury, sulfur, nitrogen, and greenhouse gases. 
  • Hydrogen is used as a fuel source for cars
  • Nuclear Energy
  • Hydropower
  • Solar power
    • used in residential and commercial applications


  • Wind power
    • windmills and power plants are seen throughout the United States
    • two main problems with it are diluteness and intermittency


  • Electric Power
    • It is a natural gas that is the fastest-growing fuel source for electric power
    • only 13% of electricity is from a renewable source
    • 42% of electric power is created from coal
  • Fusion Plasma


Mechanical Systems
  • HVAC
    • Stands for Heating, ventilation, and air conditioning and provides human comfort
  • Heating systems
    • Hydronic
      • Water boilers used in large buildings or multi building complexes
      • Radiators are used in more residential settings
    • Air
      • This could be like a furnace
    • Electric 
      • Radiant heat relies on heating the surface of a space such as walls, floors, and ceilings
    • Woodstoves
      • high-efficiency wood burning systems can warm large spaces
    • Fireplaces
    • Geothermal Systems
      • natural occurring energy from below the earth's surface
  • Cooling systems
    • can be provided in
      • avoiding heat gain
      • passive cooling strategies
      • mechanical cooling
        • heat pumps
        • central station
        • split system
        • through wall units
  • the placement of ducts, registers, and returns need to be integrated into the design and coordination with light fixtures, sprinkler heads, projectors and screens, smoke detectors, and ceiling design details are used to ensure that the design intent and functional properties of the space have been realized.

    Hey you got the right chapter up! Unfortunately I cannot see your pictures. Good overall summary, I appreciate how you broke it into bullet points to make it easy to read!

Week 7: Ceilings

 Interior designers don't deal with roof framing, since it is a structural issue They do need to respond to the shape of the roof as it shapes interior spaces The ceiling finish also falls under the realm of the designer.  Ceilings Cathedral ceilings/sloped ceilings Pros made popular during the 1970's Provides a sense of spaciousness Popular in Residential and Commercial design Cons Integration of lighting Issues of proper heating and cooling Creation of the sense of human scale within the space Directly applied ceilings gypsum wallboard A directly applied ceiling that attaches to the building structure most commonly used ceiling finish within the residential environment plaster Plaster is applied over a three-coat system over lath This finish used before wall board on walls and ceilings In historical buildings plaster was used for crown molding or ceiling medallions Suspended acoustical panel ceilings (SAPC) Grid types Material types Preferred ceiling treatment in the commerc...

Week 11: Indoor Environmental Quality

 Acoustics How sounds travel and are heard Noise and unwanted sound Typical decibels of various sounds  the limit of human comfort is 110-120 Noise reduction coefficient (NRC) is the typical materials that are rated as far as the materials absorption capacity Sount Transmission class (STC) is the capability of a material to absorb sound Reverberation Time (RT) Sound that is built up in a room over time (echo) can be controlled Important when designing auditoriums, classrooms, lecture halls, music rooms, and performance facilities The principles of Room design partitions sound waves travel directly through wall studs, from one room to another. Staggered wall studs can disrupt the travel of the sound waves from room to room Room volumes  generally designers keep the room volume low when low reverberation times are desired larger spatial volumes are desirable in spaces such as performance halls when high reverberation times are desired.  Privacy Acoustical Partitions pr...

Week 6: Flooring

 Wood Floor Framing Systems: Light frame uses multiple small wood joints to carry a load Heavy timber frame relies on columns and beams to carry a load Structural steel floor framing system relies on regularly placed column that support steel beams. Girders span the beams and carry the metal decking. concrete is poured into the metal decking to create the floor system  Open web steel joists are used to carry metal decking for a concrete metal decking floor system Concrete as a flooring system is either poured in place on site or cast at a plant and assembled on site Floor insulation must be installed to keep cold air from the ground from moving into the finished space above. Insulation is used when a floor is installed above a crawl space or above the earth  Interior floor material multiple materials are used Use of the space and building code requirements narrow type of floor finishes to use this is divided into hard and soft surfaces.  Hard surfaces concrete used a...
