Energy Management Open Source Software for Small and Medium-sized Commercial Buildings
Commercial Buildings account
for 20% of total energy consumption in the United States. The larger units use
management systems or automation systems BAS to improve comfort and reduce
energy costs; however, small and medium sized commercial building, which
account for half the sector’s energy usage and 95% building stock, lack cost-effective
BAS solutions and the resultant savings.
Property Owners are often Unaware
of Energy Waste and BAS Savings Opportunities
Load Types
there
are three major loads in commercial buildings: HVAC, lighting and plug loads.
According to the data from EIA published in 2008, electricity use by HVAC
equipment accounts for 30% of the total electricity consumption, lighting loads
use 38% and plug loads 6%.
Cost and Interoperability BAS
systems need to become much more inter-operable, scaleable, and easy to deploy by
utilizing open architectures, plug-and-play and providing local or remote monitoring.
Most systems currently use proprietary architectures requiring building owners
and controls designers to purchase devices and controllers from a single vendor
instead of optimal products, controls, and services from different vendors.
A turn-key solution that reduces installation and maintenance costs. In addition,
it is a scaleable and broadly inter-operable solution with seamless HVAC,
lighting, plug load equipment and controller integration from different
manufacturers, hence plug-and-play functionality for the many system
configurations found in smaller commercial architectures.

Savings of 10% for HVAC and 15% for Lighting loads
Benefits the system
provides small-sized commercial building owners access to flexible,
cost-effective building energy management that streamlines operations and optimizes
energy usage. Also, the greater interconnection between building systems and a
centralized control structure facilitates demand response, providing additional
savings and better integration with the electric power grid.
