With rising energy costs and the move toward more sustainable buildings, increasing energy use in buildings has both financial and environmental consequences. So it’s critical for building owners and facility executives to determine if their buildings are operating as efficiently as they can and if not, having the ability and control to do so.

Currently, U.S. buildings consume two-thirds of our
power supply and emit 40 percent of the greenhouse gases. This is a staggering
statistic, especially when you consider that right now we have the proven
technical capability and applications to cut these numbers in half, at a very
reasonable cost. But, in order to accomplish this, we must change the approach
to how we manage and control our buildings.
Let’s look at some facts:
Commercial buildings are the largest single consumers of energy in North America.
Buildings consume two-thirds of our power supply and emit 40% of the greenhouse gasses.
HVAC accounts for 40% and lighting accounts for 28% of a building’s total energy load making them the biggest opportunities for energy savings strategies.
In addition to raw energy savings, HVAC and lighting also have the greatest impact on occupant comfort and productivity.
Energy costs represent about 30% of an office building’s total operating costs (excluding staffing costs).
Energy efficiency is the quickest, the least expensive, cleanest way to extend our global energy supplies.
Energy management and control can provide 4x the environmental impact compared to producing new sources of renewable energy.
Nearly 2/3 of the building owners that have invested in energy strategies and energy technologies for their existing buildings have received positive ROI, including, but not limited to, higher lease and occupancy rates.
Increasing energy efficiency in buildings and other non-transportation sectors could yield a 23% drop in energy use by 2020, save the U.S. economy $1.2 trillion and reduce greenhouse gas emissions by 1.1 gigatons annually.
Existing technology and energy programs reduce energy usage by as much as 50% over conventional buildings, with the most efficient buildings currently performing up to 70% better than conventional properties.
Real World Applications |
The biggest challenge currently facing existing
buildings in reducing energy usage is the lack of manageability for efficiency
and critical information about operating systems. Traditional building systems
are characterized by highly proprietary offerings with limited ability to
connect and interoperate with each other and manage them collectively as a fully
integrated system. As a result, conventional buildings suffer from the inability
to communicate and intelligently manage the data that they possess and use this
information to drive energy efficiencies and reduce energy costs.
The vast majority of energy management activities are based on the financial
impact they will have on the company. Today’s rapidly evolving energy markets
are forcing organizations to consider new ways to centrally manage the energy
portfolio of the company. These two real-world conditions are causing building
owners and energy managers to look for solutions to integrate and coexist with
the rest of the enterprise building information network. Energy managers are
looking for an Internet friendly, integration framework that bridges the gap
between the business layer and the operational layer of the enterprise.
Low/reduced-energy buildings are being built by
developers and business owners across the country with a zero or marginal cost
premium. This can also be said for retrofitting existing buildings with energy
saving technologies. Market leaders have already figured out that high energy
and operational costs are affecting the profitability of their buildings and
portfolios and that these costs are rising. They know that tenants want
environmentally friendly features and successful businesses care about employee
comfort and productivity.
By managing energy and facilities as investments, companies gain control of
energy use and achieve high rates of return in the form of energy savings and
better performance with their buildings. Benefits from this investment approach
can include double digit energy reductions, as well as improved building
performance, lower operating costs, increased worker productivity, and
environmental responsibility.
Perhaps no other technology has had as profound an impact on smart energy
solutions, making more energy efficient buildings and reducing energy usage and
costs than the Internet. The success of the internet is largely driven by open
protocols and standards that enable all sorts of applications and hardware to
interact. We think the same principles of openness that have made the Internet a
thriving ecosystem should be applied to help all of us save energy, save money
and contribute to a sustainable environment. Tridium’s NiagaraAX Framework® has
and remains at the forefront for doing this.
The Niagara Framework has been a major player in making buildings more energy
efficient, reducing energy usage and driving down costs for over 12 years.
Today, there are over 162,000 instances of Niagara operating in 45 countries
worldwide in office buildings, manufacturing plants, mission-critical
facilities, hospitals, educational and government campuses, military bases,
hotels, retail stores and airports.
Niagara helps both small and large organizations integrate, measure, manage and
reduce energy costs through enhanced integration and systems management and
provides energy management capabilities for large campuses and geographically
dispersed enterprises.
Built on an open architecture, the Niagara Framework merges multi-vendor
automation systems and real-time integration into a single, extensible platform
that monitors, manages and controls the power consumption of all building
systems and drives energy efficiency and reduces energy costs. Niagara takes
into account all critical areas that form the subsystems that make a building
function including lighting, heating, ventilation and air-conditioning (HVAC),
security, and energy management. It allows devices to share information with
each other and streamlines them into a common system where management can
control and monitor the buildings’ operations.
Niagara has removed the barriers to assess the proprietary and legacy data from
different systems in a facility. It is the bridge between systems and devices
and simplifies the process of connectivity and integration that makes building
and facility management easier.
Niagara is a scalable platform that delivers measurable ROI enabling users to capture the benefits of integration, automation and energy control of their buildings and maximize the value of information in real-time contained within them.
In addition to integrating energy consuming devices
and systems within a building and getting them to work together to be managed,
controlled and operate at optimum levels, Niagara also includes energy
measurement and verification tools options that allow users to implement the
most efficient and sustained energy strategies in a building today.

As a real-time integration platform and automation infrastructure, Niagara
allows users to deploy optimal energy and environmental management strategies
that notifies about events before they occur and provides users with the tools
to execute control such as schedule and temperature adjustments or activation of
on-site generation. Niagara interacts in real-time, with the systems that
control the energy consuming and generating equipment in a facility.
The technology also enables users to collect information and benchmark buildings
to expose operational inefficiencies. From a green building perspective, Niagara
allows users to capitalize on accurate and concise intelligence relating to the
energy performance of a building in order to achieve lower energy consumption
and enhanced efficiencies.
Summary
Niagara Creates Better Buildings
Niagara is an actionable platform enabling building owners and managers
to proactively achieve significant energy savings. With its easy to use features
and proven energy saving capabilities, the Niagara Framework is successfully
addressing today’s energy challenge. The solution not only allows for complete
integration, manageability and control but also allows for predictive as well as
preventive detection in buildings anywhere, anytime.
By integrating today’s diverse building systems such as environmental controls,
security, lighting, energy, video, fire and life safety, The NiagaraAX Framework
is creating better buildings---ones that are smarter, use less energy, are more
efficient, have lower operating costs, are safer and contribute to a sustainable
environment.
