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
- 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
- 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
- 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
- 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
- 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
- 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
