Cost Free Energy Living How does it work? Identify energy demands of each home for space heating, water, cooling, air leakage, wall and attic insulation, lighting & appliances. A photovoltaic system is installed to offset 100% of the modeled electrical demand of the house. Systems are approved and registered with Nevada Energy's net metering program.

"A house payment for $750 a month, including mortgage and energy costs."

HERS Index

The Rem/Rate analysis performed on the homes establishes a Home Energy Rating System Index that serves as an energy efficiency comparison. After incorporating recommended energy measures into 4D Investments, average energy reduction can be up to 165%, allowing Cost Free Energy Living!
