FAQs In Energy and Facilities Management

The variety of factors that influence how much energy a building consumes and the pressures energy and facility managers face in balancing various priorities can be overwhelming. We have compiled a list of common questions below with links and guides as a meaningful resource for those managers.


What is Adaptive Energy Management?

Adaptive Energy Management (AEM) is an around the clock strategy that monitors and regulates building control systems, such as HVAC, in a dynamic approach. This approach takes into consideration multiple data sources, including current and historical weather conditions and occupancy levels, and optimizes building and mechanical systems based on the overall data. 

AEM can increase profit, comfort, and efficiency by such things as:

  • “Flattening” load shapes through optimized equipment scheduling and fine tuning of control loops ahead of peak demand times when electric rates are significantly higher
  • Alerting management of required system maintenance, which can maximize the life of equipment
  • Leveraging external data from systems such as ERP, CMMS, Utility Bill Accounting and others

How does benchmarking help in facilities management?

Benchmarking allows facility and energy managers to assess and evaluate a building’s performance relative to the rest of their portfolio. Primarily, maintenance costs, energy demand and consumption, individual unit efficiency, and asset management are key metrics taken into account.  

Setting benchmarks allows managers to measure and validate projects that provide a compelling ROI, highlight productive areas, and identify operational or infrastructure issues. Benchmarks also allow for better planning of eco-friendly and/or upgrade projects.

What is closed loop control?

Closed loop control, through the use of machine learning algorithms, fine tunes the operation of the control system; in real-time. The addition of the machine learning algorithm effectively creates more precise loop control, adding an enormous amount of value for a building manager who is trying to balance the demands of managing a building effectively.

What is Delta T?

Delta T is the temperature difference of the air before and after it passes through the coil. Delta T is one of the most common measurements used in the HVAC industry. To calculate, subtract the return air temperature from the supply air temperature. For example, if the supply air temperature is 75F, and the return air temperature after cooling is 55F, the Delta T is 20F.
 
When cooling, a Delta T between 16-22F is optimal. When heating, the range depends on the system, but it can go up to a 30-degree spread.
 
Typically with high Delta T readings, there is low airflow across the coil, which can be due to dirty air filters, incorrect fan speed, dirty evaporator coil, or an issue with the ductwork.

What are Distributed Energy Resources? 

Distributed Energy Resources (DERs) are small-scale power generation or power storage methods. These methods either generate energy or enable the buffering of that energy to provide greater flexibility to the main grid.  

DER examples include:

  • Solar power 
  • Fuel Cells
  • Compressed air
  • Microturbines
  • Thermal energy storage 
  • Electrochemical Batteries  

DERs are also referred to as on-site or BTM energy generation.

What are good building energy management systems? 

A robust building energy management system allows managers to conserve and reuse energy in dynamic ways by capturing data from all of the building’s electrical devices, mechanisms, etc. The management system needs to give managers the ability to identify issues, automate responses, automate alerts for troubleshooting and maintenance, evaluate benchmarks, and isolate and recommend ways to reduce energy waste.

What is load shifting?

Load shifting occurs when a building redistributes electric kW demand to “off peak” hours when grid energy is considerably less expensive.

What are retail energy management solutions?

Retail energy management solutions refer to the computers and devices that monitor and control a retail store’s (or retail chain’s) energy use. Lighting and ventilation account for the bulk of energy use in retail, so it is important to capture this data at every location a retail chain may manage. Once data is coming in, software can automate monitoring and help isolate issues and areas where energy consumption can be reduced.
