As the DOE reports, companies can achieve energy savings between 3 and 9% over a two-year timeframe with analytics. With intelligent analytics from a master systems integratort (MSI) and controls expert like Buildings IoT, you can achieve up to 10 to 25% energy savings.
By extracting insightful and actionable real-time, prioritized data for commercial and multi-site properties, building owners and operators have a new and powerful tool to address the sizable percentage of waste and inefficiencies that are occurring across their facilities.
As you strive toward exceeding energy efficiency and savings goals for your commercial buildings, you may need help from an experienced partner to develop a successful energy-savings strategy for a truly optimized, seamless system. There are several specific intelligent energy efficiency areas where an expert partner—Buildings IoT—can help:
Comprehensive Energy Management and Performance Tracking
By working with an advanced analytics partner who can track historical data from your systems, you will soon have a baseline for a comprehensive energy efficiency plan. This plan will include actionable areas for maintenance and change management, streamlined reporting and monitoring, and an approach for controlling equipment and devices more efficiently.
The process begins with collecting and analyzing a range of in-depth systems and their data in a more structured and manageable way, and predicting energy demand and consumption based on historical and real-time usage.
Powerful data analytics tools working in conjunction with advanced machine learning (ML) can:
- Enable timely and accurate insights.
- Be used to plan an improved approach to maintenance.
- Identify beneficial device configuration changes that could be made.
- Target areas that could benefit from the use of automation to streamline systems.
Energy performance tracking requires a fine balance of intelligent analytics, remote monitoring, and automated device control to produce energy savings. It can be broken down by specific high energy-consuming systems, like HVAC and lighting, and other equipment and devices.
Heating, ventilation, and air conditioning (HVAC) systems are in almost all cases the highest energy-consuming equipment, using an astonishing 40-60% of total commercial building consumption. Through advanced analytics solutions such as onPoint, commercial building owners and facility managers will discover major efficiency benefits for the HVAC system itself, as well as its interconnected BMS and related equipment. For the best energy management to maximize efficiency, analytics systems should enable:
Meaningful, Simplified Insights
Intelligent analytics related to your HVAC equipment like fan coil units, variable air volume (VAV) systems, etc. will help you to:
- Identify and address zone setpoints that are causing excessive heating or cooling demands. This may include unreasonably tight deadbands or infrequently occupied areas.
- Adjust equipment schedules based on demand to ensure occupant comfort while minimizing equipment runtime and energy consumption.
- Understand optimization opportunities for efficient system operation with an experienced controls partner who can deliver a complete solution.
The right partner will evaluate how your HVAC system is performing and manage automated temperature setpoints according to outside temperatures and other environmental influences. Through detailed analysis and proactive maintenance suggestions, you will:
- Improve system efficiency and prolong your HVAC’s life to achieve maximum, long-term energy savings.
- Improve occupant comfort and reduce equipment downtime.
Cogeneration can powerfully reduce carbon emissions and ensure that the major load on your HVAC system is reduced, redirecting wasted heat and power production to heat your buildings’ water.
Keeping your air vents clear and free of obstructive articles will help reduce your energy bills. As blocked ventilation causes 25% more energy to be consumed inside a building, maintaining clean and clear ventilation will help save energy and reduce your energy bill. You can also implement air quality monitoring sensors to help improve the energy efficiency of your ventilation system.
HVAC systems play a critical role in commercial building energy efficiency. When your HVAC system controls are automated and set up to consume less energy, you will experience greater energy efficiency and reap substantial cost savings benefits.
Lighting is generally another high energy consumer. And while the simplest way to reduce energy consumption is by turning off lights during no-to-low occupancy periods, you can also consider natural light, energy-efficient windows, and skylights.
Often, the obvious cost savings opportunities, however, are not enough to substantially reduce your energy usage related to lighting so that’s where lighting control technologies and advanced analytics come into play. An expert partner with energy management experience can:
- Consult on the best occupancy sensors you can install to automatically dim or turn off lights as rooms become unoccupied.
- Schedule lighting controls to automatically dim or shut off lights at specific times of the day—at the end of a typical workday for example.
- Implement demand-responsive lighting automation for dimming or turning off lights during high electricity pricing periods of the day.
Building automation is used to control the lighting systems throughout your buildings. And because artificial lighting consumes 35-75% of a site’s overall energy usage, that makes lighting and these techniques significant for improving your energy efficiency and potential savings.
Energy efficiency for commercial buildings is difficult to achieve when you have systems malfunctioning and equipment and devices consuming unnecessarily high levels of energy. And sometimes those systems—such as breakroom appliances and huddle room equipment—are not being reported by your BMS.
By gaining visibility into energy consumption and waste at a granular level—by ensuring all equipment is connected through your BMS and adding analytics into your building management system, you can employ simple cost-effective techniques such as:
- Putting your equipment into “sleep mode” when inactive to save substantially on energy bills.
- Powering down equipment at night when no one is using it.
- Reporting on equipment operation by system and validating work completed has actually fixed a problem.
- Monitoring and uncovering patterns within large datasets of your operational systems even down to the smaller end-points and most energy-consuming devices to help you to detect faults and excessive energy usage before they spiral into higher energy bills.
- Reducing operational costs related to equipment maintenance and emergency service calls.
