ESG for Small Landed House

 

 

ESG Style Home System (Landed)

 If you’re planning a new small landed house, this is actually the best time to integrate an ESG-style home system because it’s cheaper and more effective than retrofitting later. In a residential context, ESG 
  • E (Environmental): energy, water, waste efficiency 
  • S (Social): health, comfort, livability 
  • G (Governance): smart control, monitoring, maintenance discipline 

 Below is a practical ESG system design for a small landed house in Malaysia. 
  1.  ENVIRONMENTAL (E) – Core sustainability systems 
    • Solar + Energy Efficiency (high impact) 
      • What to include: 
        • Rooftop solar PV system (3kW–6kW for small house) 
        •  Optional battery storage (for backup) 
        •  LED lighting throughout house 
        •  Inverter air-conditioning (high efficiency) 
      •  Design tip: Orient roof for maximum sunlight capture (south-facing in Malaysia is ideal) 
    • Rainwater harvesting system 
      • What to include: 
        • Roof gutter collection system 
        • First-flush diverter (removes dirty rainwater)
        •  Storage tank (1000L–5000L)
        •  Pump for garden/toilet use 
      •  Use for: 
        •  Garden watering 
        • Washing car/floor 
        • Toilet flushing (advanced stage) 
    • Waste separation + compost system 
      • What to include: 
        • 3-bin waste system (recycle / compost / general waste) 
        • Small composting corner in garden 
        • Optional Bokashi indoor system 
      •  Benefit: 
        •  Reduces landfill waste 
        • Creates free fertilizer for garden
    • Passive cooling design (VERY important in Malaysia) 
      • Design features: 
        • High ceilings (improves airflow) 
        • Cross ventilation windows (opposite walls) 
        • Roof insulation (reduces heat) 
        • Extended roof eaves (blocks sun)
        •  Light-colored roof tiles (reflect heat) 
      •  This reduces aircond usage significantly. 
  2.  SOCIAL (S) – Comfort, health, liveability 
    •  Natural lighting design 
      • Large windows in living + dining area 
      • Skylight (optional for stairway/central area) 
      •  Reduces electricity use + improves mood 
    •  Green space integration 
      • Small backyard garden 
      • Vertical garden wall 
      • Herb garden (kitchen access) 
      •  Even 10–20% green area improves cooling effect 
    •  Functional layout planning 
      • Easy flow between kitchen–dining–yard 
      • Accessible storage (reduces clutter) 
      • Separate “dirty” and “clean” zones (important for hygiene) 
    •  Acoustic comfort 
      • Insulated walls (reduce outside noise) 
      • Double-glazed windows (if budget allows) 
      • Soft interior materials (curtains, rugs) 

  3.  GOVERNANCE (G) – Smart monitoring & control 
    •  Smart home system (basic level) 
      • Smart lighting (app-controlled) 
      • Smart plugs (energy monitoring)
      •  Motion sensors (lights in corridors/toilets) 
      • Benefit: 
        •  Tracks electricity usage 
        • Reduces waste consumption 
    •  Energy monitoring system 
      • Smart meter or sub-meter for: 
        • Aircond 
        • Lighting 
        • Water pump 
      •  Helps you identify high-cost usage areas 
    •  Maintenance planning system 
      • Simple digital checklist (phone app) 
      • Monthly checks for: 
        • Water tank 
        • Solar system 
        • Roof gutters 

  4.  SMART ESG HOUSE LAYOUT IDEA (Simple zoning)
    • Front zone: 
      • Parking + solar roof above car porch 
    • Middle zone: 
      • Living room + dining (natural light focus) 
    • Core zone: 
      • Kitchen + utility + waste sorting area 
    • Back zone: 
      • Garden + rainwater tank + compost system 
    •  This creates a natural ESG flow: energy → living → waste → reuse 

  5.  Estimated ESG setup cost (small landed house) 
    • System Cost Solar system RM 15,000 – RM 35,000 
    • Rainwater harvesting RM 1,500 – RM 6,000 
    • Compost system RM 100 – RM 800 
    • Smart home features RM 500 – RM 3,000 
    • Passive design (construction stage) RM 2,000 – RM 10,000 (depends on build choices) 

  6.  BEST PRACTICAL ESG PACKAGE (Recommended) 
    •  If you want a balanced, realistic setup: 
      •  Must-have (high ROI): 
        • Solar (at least 3kW) 
        • Rainwater harvesting 
        • Passive cooling design 
        • Basic smart lighting 
      • Nice-to-have: 
        • Compost system 
        • Smart energy monitoring 
        • Garden + vertical green wall 

  7.  FINAL RESULT (what you achieve) 
    •  A properly designed ESG home in Malaysia gives you: 
      •  Lower electricity bills 
      • Lower water bills 
      •  Cooler indoor temperature 
      • Less waste production 
      • Higher property value 
      •  More comfortable living long-term
