Abstract

A building management system includes building equipment, a metric generation system, and a visualization engine. The building equipment is configured to generate data samples. The metric generation system is configured to collect the data samples and generate key performance indicators. The visualization engine is configured to create a scorecard that displays the key performance indicators. The scorecard comprises a building energy overview widget that displays total consumption of a building, a consumption by space widget that displays consumption of a plurality of subspaces of the building, and a consumption by commodity widget that displays consumption of the building categorized by commodity. In some embodiments, the scorecard also includes an energy density by space widget that displays consumption per unit area per day for the subspaces of the building.

Claims

1. A building management system comprising:

building equipment configured to generate data samples;

a metric generation system configured to collect the data samples and generate key performance indicators; and

a visualization engine configured to create a scorecard that displays the key performance indicators, the scorecard comprising;

a consumption by space widget that displays consumption of a plurality of subspaces of the building;

a consumption by commodity widget that displays consumption of the building categorized by commodity; and

a consumption by peak demand by space widget displaying a thermal map, the thermal map comprising a plurality of cells corresponding to a plurality of subspaces of the building, wherein a cell has an area determined by a peak demand value and a color determined by a demand value of the subspaces.

2. The building management system of claim 1, the scorecard further comprising an energy density by space widget that displays consumption per unit area per day for the subspaces of the building.

3. The building management system of claim 1, the scorecard further comprising a consumption by load type widget that comprises a ring chart, the ring chart comprising a plurality of sections that combine to form a ring, each of the sections corresponding to a load type and having a size defined by an angular dimension, wherein the angular dimension of each section is proportional to a consumption metric attributable to the corresponding load type.

4. The building management system of claim 1, the scorecard further comprising:

an energy density by space widget that displays consumption per unit area per day for the subspaces of the building;

a consumption by load type widget that comprises a ring chart, the ring chart comprising a plurality of sections that combine to form a ring, each of the sections corresponding to a load type and having a size defined by an angular dimension, wherein the angular dimension of each section is proportional to a consumption metric attributable to the corresponding load type.

5. The building management system of claim 1, further comprising an interface generator configured to generate a user interface that displays the scorecard in a single view.

6. The building management system of claim 5, wherein the user interface allows the user to select a timespan that defines a set of data samples to be included in the key performance indicators displayed on the scorecard.

7. A method for monitoring and controlling a building, the method comprising:

operating building equipment to generate data samples;

collecting the data samples and generating key performance indicators;

generating a scorecard that displays the key performance indicators, the scorecard comprising;

a building energy overview widget that displays total consumption of the building;

a consumption by space widget that displays consumption of a plurality of sub spaces of the building;

a consumption by commodity widget that displays consumption of the building categorized by commodity; and

a consumption by peak demand by space widget displaying a thermal map, the thermal map comprising a plurality of space-cells corresponding to a plurality of subspaces of the building, wherein a cell has an area determined by a peak demand value and a color determined by a demand value of the subspaces.

8. The method of claim 7, the scorecard further comprising an energy density by space widget that displays consumption per unit area per day for the subspaces of the building.
