Energy-Efficient Homes: Building Green in Central Park
Lahore's summers are brutal and getting worse. An energy-efficient home is no longer a luxury; it is a financial necessity. The right insulation, glazing, and solar setup can cut utility bills by 40–60% and add a measurable premium on resale.
Insulation and glazing: the biggest levers
Roof insulation with polyurethane foam and double-glazed windows are the two upgrades with the fastest payback. A 5 marla home with both runs air conditioning 25–35% less in peak summer.
Solar and battery economics in 2026
A 5 kW solar system with battery backup currently costs PKR 6–8 lakh installed. For a 10 marla home with high AC load, the payback period is four to five years against grid tariffs.
Water conservation and heat reduction
Underground water tanks, rainwater harvesting, and reflective roof coatings all reduce both water bills and indoor temperatures. Green roofs are increasingly viable on flat-slab homes.
