Can Smart Building Software Lower Apartment Operating and Energy Costs?

The short answer: yes, when it removes work rather than adding another dashboard. The savings come from fewer manual access changes and trips to units, fewer separate software subscriptions, energy setbacks in vacant units, earlier leak detection and new resident service income. How much depends on the building, its equipment and how it is run, so measure a baseline before you start and compare the same property after.

Where the savings come from

  • Labor that disappears. When move-ins, transfers and move-outs drive access and services automatically, staff stop re-entering the same information in several systems.
  • Fewer trips to units. Remote access for vendors and self-guided tours, remote thermostat changes and device health alerts reduce truck rolls.
  • SaaS consolidation. One operations platform and one resident app can replace several separate portals.
  • Energy. Vacant units can switch to energy-saving schedules automatically and return to the resident at move-in.
  • Water damage avoided. Leak sensors alert the right person, and a compatible valve can shut water off.
  • New income. Resident services such as internet, TV and local perks can be offered through the same app.

An example, with its limits

Regius Square, a 124-unit community in Salt Lake City managed by Asset Living, reported 35% lower energy costs and 43% fewer resident complaints after its systems were connected on Della OS. Those are one property's results. Energy savings depend on climate, equipment, occupancy and how the building is run, so treat any single percentage as an example, not a promise. Read the case study.

How to measure it honestly

  1. Record a baseline: energy use for vacant and occupied units, staff time per move-in and move-out, calls to the office, water incidents.
  2. Change one thing at a time where you can.
  3. Compare the same property over the same season after deployment.
  4. Report results per property, with the baseline and measurement period.

Is smart building software worth it for a small portfolio?

Often, if you start with the outcomes that remove the most manual work. Many owners begin with software only (PMS sync, the resident app, messaging, amenities and maintenance) and add devices later. With Della OS, about 60% of capabilities need no new hardware.

Where Della OS fits

Della OS connects the PMS, building systems and people so work is eliminated rather than moved around. Your PMS runs the business. Della runs the building.

Frequently asked questions

Can smart building software reduce apartment energy costs?

Yes, mainly through automatic vacant-unit setbacks, remote climate control and leak detection. Savings depend on the building and should be measured against a baseline.

Can smart building software lower multifamily operating costs?

Yes, by removing manual access and data-entry work, reducing trips to units and consolidating separate software.

Is building automation worth it for a small apartment portfolio?

Often, if you start with software-only outcomes that remove manual work, then add devices over time.

Does Della OS guarantee a percentage of energy savings?

No. Results depend on each building. Regius Square reported 35% lower energy costs, which is one property's result.
