Portfolio Energy Manager - Setup

When it comes to energy management of your building portfolio, 75F offers the Portfolio Energy Manager (PEM). Here you can see historical derived and metered energy data. Whether you manage one building or 200 the PEM is an excellent resource. 

Derived Data

Given the specifications of your HVAC unit 75F is able to derive what the theoretical energy consumption of your equipment is, or should be, given the runtimes. That said, theory is not always perfect and the real world has other factors that play into the actual energy consumption. 

Metered 

Using a revenue grade energy meter you are able to compare unit loads to building loads, or derived loads to actual. Giving you the data to determine if your HVAC equipment is running with peak performance. 

Setup

Currently, for quality purposes, a 75F representative must input all equipment data for the portfolio energy manager. What you need is the name plates or RTU characteristics for each of the units controlled by 75F. 

For your reference and understanding, below shows how the PEM is setup. 

1. Collect the HVAC characteristics.
2. Calculate consumption. Given the RLA and the RTU voltage, we can calculate the Kw consumption of the unit. 
3. Input the data and create the map. 

To input the data and create a building energy map, we use an internal energy portal. Below is a full view of the Energy configuration dashboard. 

Note the red exclamation on "Smart Stat 5.0.5". This calls attention that no unit characteristics have been entered. Meaning that nothing can be derived yet. 

If you click on one of the yellow boxes that indicate a unit. You will then get the box below where you can enter the unit characteristics.
