TS Studio: Decrease Bills

This is an explanation of how Eco Living gameplay effects work in the game. It doesn't sound like buy objects use the function.

BUILD MODE ITEMS GRANT GAMEPLAY EFFECTS

How you build your lot can now affect your gameplay. Certain objects such as wall patterns, floor patterns, fences, and columns bring different gameplay modifiers. Some of these modifiers affect how your Bills and utilities are calculated by decreasing or increasing your Power or Water utility production or usage, as well increasing or decreasing the price of bills. Environment Score can now be impacted by certain objects and materials. Drywall walls without wall patterns applied now decrease environment score like they did in The Sims 3! The choice of floor and wall materials used can also affect the ability to spread fire or puddles at an increased or lessened rate. And if you’d rather build your lot without having to think about these things, don’t worry. There’s an Option in the Gameplay menu to turn all of this off.
