SMART ENERGY ANALYSIS CALCULATOR – AN INTERACTIVE TOOL FOR AUTOMATING BUILDING ENERGY ANALYSIS & EXPEDITING ENERGY AUDITS
The Smart Energy Analysis Calculator (SEAC) is a
client-interactive calculation tool that identifies energy
conservation measures in existing buildings, along with
the associated energy and cost savings. SEAC combines
an energy analysis performance with an automatically-
generated building energy model using the Rapid
Building Energy Modeler (RAPMOD) technology.
SEAC will add value and accuracy to energy analysis,
audits and energy simulations and empower owners and
building mangers during the building retrofit process.
SEAC applies an automatic process flow and procedure
to utilize building and system input data collected by
RAPMOD. With hourly based schedules and local
weather data to implement the anisotropic HDKRModel,
SEAC is rooted on a transient 4-capacitorsimplified
energy model to determine the resulting
thermal response and quantities for reactive building
loads and temperatures. Using American and German
green building codes and standards, this methodology is
applied to improve accuracy and reduce the required
time for energy analysis and audits. Modeled energy
usage is benchmarked against manually input utility,
energy rating scores and ASHRAE 90.1:2010, and is
analyzed to suggest potential energy conservation
measures and estimate associated costs and energy
savings. This paper describes the design and calculation
approach for creating the SEAC tool and the
implementation of RAPMOD into the automatic process
