Low Budget ESG House (RM 5000)

 

LOW BUDGET ESG HOUSE (RM 5000)

 
We’ll simplify ESG into 3 practical parts: 
  •  E (Environment): save energy + water + waste 
  •  S (Social): comfort + livability 
  •  G (Governance): simple tracking + control 

  1. ENVIRONMENT (BIGGEST SAVINGS IMPACT) 
    • Basic solar lighting support (not full solar system) 
      •  Instead of full solar PV (too expensive), do this: 
        •  Solar garden lights (outdoor) 
        • Solar wall lights (car porch / gate area) 
      •  Why: 
        •  Reduces outdoor electricity usage 
        • Improves security lighting automatically 
      •  Cost: RM 150 – RM 600 
    •  Mini rainwater harvesting system (DIY) 
      • Setup: 
        • 1 x 1000L water tank (or 2 x 500L drums) 
        • Gutter pipe diversion 
        • Basic mesh filter (leaves/debris) 
        • Tap outlet 
      •  Use for: 
        •  Garden watering 
        • Car washing 
        • Floor cleaning 
      •  Cost breakdown: 
        •  Tank: RM 300 – RM 900 
        • Pipes + fittings: RM 200 – RM 500 
        •  👉 Total: RM 500 – RM 1,400 
    •  Simple compost system (DIY) 
      • Setup: 
        • 1 plastic drum / bin (drilled holes) 
        • Dry leaves + kitchen waste layering 
        •  Optional: Bokashi bucket for indoor kitchen scraps 
      •  Cost: 
        •  DIY compost bin: RM 50 – RM 150 
        • Optional Bokashi: RM 100 – RM 200 
        •  👉 Total: RM 50 – RM 300 
    •  Passive cooling (MOST IMPORTANT for Malaysia) 
      •  Do this during design/reno stage: 
        •  Cross ventilation windows (opposite sides)
        •  Ceiling fan in all rooms (not overusing aircond) 
        • Light roof colour (reflect heat) 
        • Basic roof insulation (foil or foam layer) 
      •  Cost: 
        •  Ceiling fans: RM 100 – RM 300 each 
        • Roof insulation (basic): RM 500 – RM 1,500 
        •  👉 Total: RM 1,000 – RM 2,000 
  2.  SOCIAL (COMFORT + LIVEABILITY) 
    •  Natural lighting design (cheap but powerful) 
      • Bigger windows in living area 
      • Use light curtains (sheer + blackout combo) 
      •  💰 Cost: RM 200 – RM 600 
    • Small green space setup 
      • 2–5 potted plants (indoor + outdoor) 
      • Simple herb garden (kitchen side) 
      •  💰 Cost: RM 100 – RM 300 
    •  Simple layout discipline (FREE but important) 
      • Built-in storage or closed cabinets 
      • Avoid open clutter shelves 
      • Separate shoes / laundry / living zones 
      •  This improves comfort more than expensive furniture 
  3.  GOVERNANCE (SMART CONTROL – LOW COST)
    • Smart plugs + energy control 
      • Control aircond, heater, appliances via phone 
      • Track usage habits 
      •  Cost: RM 100 – RM 400 
    •  Motion sensor lights (small upgrade) 
      • Toilet / corridor / outdoor lights auto on/off
      • Cost: RM 100 – RM 300 
    •  Simple energy tracking habit system (FREE) 
      • Monthly electricity + water tracking in phone notes 
      • Identify high usage rooms 
  4. FINAL BUDGET SUMMARY (LOW-BUDGET ESG) 
    • Category Cost Solar lighting RM 150 – RM 600 
    • Rainwater harvesting RM 500 – RM 1,400 
    • Compost system RM 50 – RM 300 
    • Passive cooling upgrades RM 1,000 – RM 2,000 
    • Lighting + smart control RM 200 – RM 700 
    • Plants + small green space RM 100 – RM 300 
    • 🏆 TOTAL: RM 2,000 – RM 5,000 
  5. WHAT YOU ACTUALLY ACHIEVE 
    •  Even with this budget, your house will have: 
      •  Lower electricity usage 
        • Less reliance on aircond 
        • Outdoor solar lighting 
      •  Lower water usage 
        • Free rainwater for outdoor use 
      •  Less waste 
        • Compost reduces garbage output 
      • Better comfort 
        • Cooler indoor temperature 
        • Better air circulation 
      •  More awareness of usage 
        • Smart plugs + tracking habits 
  6. SIMPLE STRATEGY (IMPORTANT) 
    •  If you do only 3 things, prioritize this: 
      •  TOP 3 (most impact) 
        • Passive cooling design (fan + ventilation) 
        • Rainwater harvesting system 
        • Compost system 
      •  These give the highest long-term savings in Malaysia climate
