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

Smart System

    Smart System A smart system (for a landed house) simply means a connected setup where your home devices—lighting, fans, aircond, sockets, water systems—can be controlled, automated, and monitored together, instead of operating separately. In Malaysia homes, a good smart system is usually built in layers, not as one single product.   WHAT IS A SMART SYSTEM?   Simple definition: A smart system is a network of devices + wiring + apps + automation rules that allows your house to:   Control devices remotely (phone/voice)   Run automatic schedules  Reduce energy waste  Track electricity usage  React automatically to conditions (motion, time, temperature)   CORE COMPONENTS OF A SMART SYSTEM    Smart Devices (the “hands”)   These are what you control:   Smart plugs (appliances)  Smart switches (lights/fans)  Smart sensors (motion, temperature)  Smart aircond controller...

It borrows heavily from traditional European architecture (think Parisian flats or stately English estates) but keeps one foot firmly in the present so it doesn't feel like a dusty museum.I n a classic luxury home, every piece feels deliberate, high-quality, and built to last. Here is how to inject that high-end, classic luxury aesthetic into your new home. Architectural Details Are Your Foundation True classic luxury starts with the bones of the room. If your new home has plain drywall, adding architectural interest is the highest-impact upgrade you can make. Applied Molding (Wainscoting or Picture Frame Molding):  Adding simple wood trim in boxes along your walls instantly elevates a room from basic to bespoke.  It adds depth, shadow lines, and that historic European flair. Crown Molding:  Take your molding all the way to...
