For senior living providers, sustainability is not a side project or a branding exercise. Done well, it is an operating strategy; one that can moderate volatile utility costs, improve resident comfort, protect capital budgets, and demonstrate stewardship. The strongest business case begins by asking not, “How many solar panels can we install?” but “How can energy investments advance our mission and strengthen the bottom line?” The answer usually involves solar, but it begins well before the first panel is installed.
