Commercial Office

The Background

After an HVAC upgrade, our client wanted to ensure that systems were well maintained and operated efficiently. The company originally piloted the Enertiv platform at two sites and have since renewed their subscription as well as expanded projects.

Client Objectives

The focus of the pilot was to enable building operators to become more responsive to operational and maintenance issues across their portfolio. The main objectives were:

  • Improve building operators’ response time to alerts and repairs
  • Identify potential energy savings
  • Quantify equipment performance
  • Optimize equipment schedules

Results

Reduction in maintenance and utility expenses, as well as extending the useful life of equipment, resulted in a payback of less than one year.

Savings

$55,000 recurring annual savings

Payback period

6 Months

Makeup air units (MAU) play a critical role in ventilating multifamily properties by supplying fresh outside air to a building. When the makeup air unit shutdown, Enertiv sent an alert to the third-party maintenance vendor. Without Enertiv, the equipment malfunction would not have been found until a tenant complaint triggered an investigation.

Vendor Accountability:
Makeup Air Unit Failure

The Background

Makeup air units (MAU) play a critical role in ventilating multifamily properties by supplying fresh outside air to a building. When the makeup air unit shutdown, Enertiv sent an alert to the third-party maintenance vendor. Without Enertiv, the equipment malfunction would not have been found until a tenant complaint triggered an investigation.

The maintenance vendor reached the site and discovered that the air filters of the (MAU)were clogged. After replacing air-filters and servicing the equipment, the unit came back online. All of this was completed without the involvement of ownership.

Properly functioning ventilation fans are critical to maintaining occupant health and comfort. Indoor air quality is highly dependent on the performance of ventilation equipment to supply remove air from a space and replace it with fresh outside air.

Maintenance Optimization:
Exhaust Fan Repairs

The Background

Properly functioning ventilation fans are critical to maintaining occupant health and comfort. Indoor air quality is highly dependent on the performance of ventilation equipment to supply remove air from a space and replace it with fresh outside air.

In addition to the Enertiv platform detecting equipment malfunctions in real time, Enertiv’s client success team leveraged equipment performance data to analyze repair times to quantify the effectiveness of maintenance practices. The comprehensive report generated by Enertiv helped focus the repair efforts so that building operators could address the issue in the most efficient manner possible.

CHP units are significant investments with attractive payback periods, provided that the unit operates continuously. For the economics to work out, CHP units must offset grid-purchased electricity while delivering useful heat. Downtime forces buildings to purchase fuel and additional electricity from the utility instead of generating it on site.

Vendor Accountability:
Combined Heat and Power Maintenance

The Background

CHP units are significant investments with attractive payback periods, provided that the unit operates continuously. For the economics to work out, CHP units must offset grid-purchased electricity while delivering useful heat. Downtime forces buildings to purchase fuel and additional electricity from the utility instead of generating it on site. In addition to the direct costs of purchasing fuel/electricity, there are costs associated with the higher peak demand on the building’s electric bill since they used an additional 65 kW of peak power which is usually provided by the CHP.

Downtime throws off the payback analysis, which assumes very limited fuel requirements for the building, and a low peak demand rate. Because CHP units are complex mechanical systems, the maintenance is often contracted to a third party. Because any downtime greater than 15 minutes will greatly increase peak demand charges, ensuring that maintenance is being performed as contracted in critical.
