Heat Reduction & Energy
Energy-efficient home renovation to lower your electricity bills
Cooler roofs, better windows, efficient lighting and smarter wiring that reduce power use without sacrificing comfort.
For most Indian households, cooling is the biggest share of the summer electricity bill. Much of that cooling is fighting heat that a better-built home would keep out.
RennovEN looks at your home as a system: roof, walls, windows, lighting and wiring. We recommend improvements that pay back through lower bills and better comfort.
Signs you need this
- High summer electricity bills
- Many old tube lights and incandescent bulbs
- Single-glazed, unshaded windows
- Rooms that need AC most of the day
The RennovEN promise
- 10-year warranty on all works
- Itemised pricing, approved before work begins
- One accountable team across every trade
- Residential specialists — homes only
Diagnosis
Why it happens
Heat gain through the envelope
Roofs, west walls and windows let in most of the heat your AC must remove.
Inefficient lighting
Older lamps waste energy and add heat.
Poor ventilation
Homes that can’t flush out warm air rely on mechanical cooling.
