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.
- 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.
- 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)
- 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
- 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
- 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)
- 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
- 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
