Video Pengajaran Pengantar Desain Arsitektur : Utilitas Bangunan Sederhana

Main ideas and lessons

1) Lecture purpose and learning outcomes

• The lecture is part of an architectural design “course achievement” (CPMK/DU) focused on the ability to create architectural design ideas using basic design methods.
• Today’s focus is the utilities of a simple one-floor building, especially:
  • Sanitation/Water systems (clean water + dirty water)
  • Drainage
  • Electric basics (lighting and related components)
• Learning flow mentioned:
  1. Understand what utilities are
  2. Study examples for:
     • Clean water sanitation systems
     • Dirty water sanitation systems
     • Drainage systems
     • Basic electricity (e.g., light point)

2) Core concept: “Utility” in architecture

• Utilities are framed as essential to ensure architecture supports:
  • Comfort, health, safety, communication, and mobility
• Utilities are described as the building equipment/facilities that complete a building so it is:
  • Practical, useful, and functions properly both inside and outside.
• Why utilities must be studied/planned:
  • Different building types (house vs hospital vs office) have different utility requirements
  • Planning utilities helps minimize waste and mistakes in installation networks (piping, electrical, etc.)
  • Improves safety, comfort, and usability
  • Makes future repairs easier via the availability of installation drawings (network layouts/plans)

3) Basic utility systems in a simple building (one-floor scheme)

• The lecture provides a “simple building utilities” overview consisting of:
  • Electricity
    • Includes lighting
    • Mentions HVAC (heating, ventilation, air conditioning) as later complexity
  • Water
    • Clean water system
    • Dirty water system
    • Drainage system
• Additional supporting systems briefly mentioned:
  • Lightning protection
  • Security system/locks
  • Internet/telephone system

4) Sanitation: definitions and water sources (clean vs dirty)

A. Sanitation definition

• Sanitation is presented as a health effort to maintain and protect the environment from harmful impacts.

B. Clean water sources

Clean water can come from:

• Wells/groundwater
• Water tanks/reservoirs
• PDAM (government/local government managed water supply)
• PAM (private sector managed water supply)

C. Dirty water categories

Dirty water includes:

• Rainwater
• Drainage
• Wastewater, divided into:
  • Black water: urine and feces
  • Grey water: liquid waste with fats (e.g., dishwashing, laundry)

D. Ending point of wastewater

• Grey/black waste is directed toward systems like:
  • Septic tank
  • Absorption/soakage well (infiltration)
  • Overflow/excess can be channeled onward to sewer/other channels

Methodology / step-by-step instructions (planning utilities)

A) Determining clean water requirement (simple assumptions)

• Assume ~150 liters per person per day
• Steps:
  1. Estimate number of residents
  2. Multiply daily need by occupants
  3. Adjust according to activities (examples):
     • Kitchen needs: washing, cooking, rinsing
     • Garden watering
     • Bathroom needs
     • Clothes washing

B) Choosing and understanding clean water distribution systems

Two main clean-water distribution methods are described:

1. Downfeed (downfit / top reservoir gravity system)

   • Source water is collected in a lower tank, then pumped up.
   • From the upper reservoir, water is distributed downward to rooms.
   • Advantages:
     • Pump doesn’t run continuously (uses gravity)
     • Reservoir above provides water availability
   • Drawbacks:
     • Requires a tank on top
     • Adds cost, structural load, and maintenance effort

2. Upfeed (upfit / direct upward pressure system)

   • Water is distributed from bottom to top directly when needed.
   • Requires a booster/push pump.
   • Advantages:
     • Often more practical for small houses/buildings
   • Drawbacks:
     • Pump runs when taps are opened
     • Height/pressure limitations (pump pressure decreases over distance)

C) Clean-water planning notes (wells, pumps, connections)

• Reservoir positioning:
  • Place tank at least at/above roof height to support gravity distribution
• Pumps:
  • Should not be directly exposed to water (not water/dust resistant)
  • Rain exposure risk: pump housing durability is a concern
• Connection types for supplied water:
  • Direct connection from public supply pipes:
    • Provides a meter/control box and then feeds taps
  • Meter location considerations (public water infrastructure constraints)
  • Combined well + public supply:
    • Multiple sources feed into a shared controlled system (valves regulate each source)

Dirty water + drainage planning requirements (key rules)

A) Separation and safe distances (clean well vs septic)

• Minimum distance between:
  • Clean water well and septic tank: 10–15 meters
• Rationale:
  • Prevent contamination and protect water sanitation/health.

B) Plumbing/delivery rules for dirty water networks

• Dirty water (untreated) should not go directly into public drainage.
• Steps for disposal flow:
  1. Route dirty water into septic tank first
  2. Then discharge to seepage/absorption area
  3. Remaining water is filtered before reaching city sewer/related channels
• Chemical warning:
  • Do not throw chemicals into septic/BC system (can damage bacteria needed for treatment)
• Channel design rules:
  • Use the shortest practical route, but ensure correct engineering
  • Keep pipes as high as possible/avoid placing deep under buildings
    • If under floor and damaged, repairs require dismantling
  • Provide control tanks, especially at:
    • Each connection or bend
    • Areas where people pass (inside/outside both mentioned)
  • Minimum vertical slope of channels: ~2%
  • Maximum diversion angle when changing direction: ~45°
  • Protect connections between tanks

C) Black water system (toilet/septic system)

• Basic routing:
  • Toilet waste → direct to septic tank (ideally minimal detours)
• Septic tank functions:
  • Solid waste settles/precipitates
  • Liquid portion flows onward after treatment
• Key safety requirement:
  • Septic tanks must include an air vent/ventilation hole to release methane gases
  • Without ventilation: risk of gas saturation and possible explosion
• Materials:
  • Septic tanks may be concrete, fiberglass, plastic, etc.
  • Bio-septic tanks also mentioned as a variation

D) Grey water system (soapy/fat-containing waste)

• Grey water characteristics:
  • Comes from soap waste (laundry/dishes)
  • Concentration is stated as lower than black water
• Routing described:
  • Goes to a control tank (to check blockage/condition)
  • Then directed to soakage/infiltration or absorption well
• Grease trap concept:
  • For soapy/fatty waste, a fat/grease catching tank is recommended
  • Grease trap can be installed inside or outside, depending on design

E) Rainwater drainage / disposal system

• Rainwater can be channeled directly into surrounding gutters because it is relatively “clean water + dirt.”
• Recommended form:
  • Open channels are suggested
• Alternative:
  • Collect rainwater into rainwater infiltration wells
• Separation principle:
  • Do not mix rainwater infiltration with dirty water absorption wells
  • Goal: rainwater can be reused (examples mentioned: watering plants, washing hands)

F) Infiltration enhancement

• Use biopore holes:
  • Increase infiltration
  • Support organic composting in the soil
  • Create small tunnels improving soil fertility

Notes on ceiling + lighting basics (electric utility portion)

Ceiling functions

A ceiling is described as providing:

• Aesthetics for the room
• Limits room height
• Heat insulation
• Soundproofing
• Space to hang lights and support installations

Ceiling types (introduced)

• Drop ceiling (lowered from original ceiling plane)
• Curved ceiling / shaped ceilings (including rhythmic curves)
• Tiered/stepped
• Ceiling with niches / recessed forms
• If no ceiling (roof exposed directly):
  • Still may use lighting arrangement directly under the roof plane

Lighting plans and electrical notation

• Lighting is designed using:
  • Ceiling plan and electrical point layout
• Lighting system details noted:
  • Ceiling plan is often separate from electrical drawing
  • Electrical point plan may also include fans/AC/exhaust fans
• Switch and circuit mapping concept:
  • Example method described:
    • Label switches (A, B, C)
    • Label lights (A1–A4, B1–B4, etc.)
    • Indicate which switch controls which light group
  • Emphasis:
    • Notation must be consistent and should include cable depiction (not only dots)
