Energy Auditing

- Consultancy Services for

energy audits

- Conduct different levels of

audits

- Shortlist energy efficiency

measures

- Submission of Detailed

energy audit report

Multiple years of experience in conducting detailed

energy audits across manufacturing sectors.

For any successful energy audit the measurements play a key role

Optimization- Data Analytics On premises/cloud based

How can I generate information from data?

• Flexible KPI/EnPI definition

• User-specific data preparation

• Data Analytics

• Access to the "right" information with one

click

• KPI definition using the drag-and-drop

function and flexible representation (widget)

Display of the data for quick decision-making

Energy Management App

Data analysis with the Chart

Data analysis manageable for all different

user

• From trend analysis until a Multivariable

Regression Analysis

• Integrated directly into the Widget

• Further extended possibilities within the

reporting

Integrated analysis functionalities supports the operator during the daily work

Application

▪ Consulting :

• Comprehensive Energy Audit Report

• Implementation strategy

▪ Implementation:

• Guarantee Energy Savings with Energy performance contracting

• System upgrade

• Shorter Return of investment

▪ Optimization :

• Energy Transparency, KPI’s setting, identify wastages

• Data analytics with energy consumption data available anytime and anywhere

• Energy savings are long term because any deviation is captured by the app

• Applicable to all the plants (Greenfield and Brownfield).
