Energy Efficiency
Efficient use of energy
to obtain desired outputs
that involves using
alternative technologies
operating at lower
energy inputs for same
purpose.
Energy Assessment
A procedure to assess the power consumption with
respect to each source.
Basic steps:
1. Determining the amount of energy being
consumed for each process/activity.
2. Determining the scope for energy savings and the
cost it takes to implement the activities.
Energy Equation
Energy Gap = Supply – Demand
Total energy production and consumption, 1980-2030 (quadrillion BTU)

Energy Assessment Spreadsheet (EAS)
Hybrid HVAC System Design Tool 1.0
Fan System Assessment Tool (FSAT)
Description
The tool helps in evaluating the sustainability of
building elements, indoor environment and the
occupant behavior, which affects the indoor living
quality. The tool utilizes the concepts of energy
efficiency, water efficiency, building envelope and
indoor environment quality, and occupant behavior to
analyze the performance offered to the occupants. This
tool was made for analyzing residential buildings and is
now being value-added for assessing the industrial
buildings as well.
The spreadsheet is a useful and easy-to-use tool for
energy assessments. It provides a complete break-up
and summaries of the total annual energy consumption
and cost. It helps in identifying avenues for energy and
cost savings
The HVAC spreadsheet is used for the design of hybrid
HVAC systems for a manufacturing facility and
associated office building. It is easy to use and could
be modified for a specific plant. It is hoped that the
spreadsheet will be helpful in improving energy
efficiency at your plant.
Help quantify the potential benefits of optimizing fan
system configurations that serve industrial processes.
Calculates the amount of energy used by fan system;
determines system efficiency; and quantifies the
savings potential of an upgraded system.
