Welcome to InnerSpace Control Strategies! A interactive blog by InnerSpace Strategies, Inc. for Facility / Building owners and engineers to view available Control Strategies for their InnerSpace. InnerSpace welcomes feedback or suggestions in order to help you maximize the capacity and efficiency of your building automation system.
Automated Logic is pleased to announce the release of a new EnergyReports™ product. With the new EnergyReports tool, building owners and operators will be able to use their WebCTRL building automation system to securely push data from a single building or a portfolio of buildings to the cloud.
With the new EnergyReports tool, building owners and operators will be able to use their WebCTRL building automation system to securely push data from a single building or a portfolio of buildings to the cloud. From there, they can create graphs, charts, reports and dashboards to visualize the building data, which will enable them to:
- Analyze and normalize energy consumption across buildings
- Compare energy costs across buildings
- Convert energy consumption data to cost or carbon dioxide emissions
- Benchmark building performance data against ENERGY STAR® scores
- Identify performance issues to maximize building efficiency
- Improve occupant comfort, productivity and engagement
- Drive energy conservation measures
The Automated Logic Environmental IndexTM tool, also known as a Comfort Index, is the ideal tool for analyzing ongoing operations as well as assessing your sustainability targets. The index rolls up granular zone data, providing you general operational insight with the ability to drill down to any zone in question.
Be in the know, 24/7
The Environmental IndexTM tool assesses how well systems are controlling, identifying problem areas and delivering the justification for remedial action.
A live, dynamic dashboard provides real-time analysis of conditions to the operator so they know exactly what is going on. With this technology, you won’t have to rely on a remote “expert” in the cloud who’s unfamiliar with your building.
We are pleased to announce the release of the Automated Logic® chilled water system optimizer. This product is a sophisticated, scalable, native BACnet optimization solution for chilled water plants. It minimizes the energy use of the entire chilled water system, up to and including air handling units and other water side chilled water consumers.
|The Automated Logic® chilled water system optimizer is a sophisticated, scalable, native BACnet optimization solution for chilled water plants. The chilled water system optimizer minimizes the energy use of the entire chilled water system, up to and including air handling units and other water side chilled water consumers. By providing optimized control of the chilled water and condenser water setpoints, the chilled water system optimizer can lower energy costs while also maintaining occupant comfort levels in the building. The chilled water system optimizer solution consists of a self-adapting control algorithm packaged in an application specific Automated Logic controller.
- It minimizes energy use over the entire chilled water system without affecting occupant comfort.
- It automatically adapts to changing conditions as the system’s conditions change over time
- It is patent pending control logic that overlays on top of dedicated equipment controls that are already in place
- It is scalable and works with the chilled water side alone, condenser water side alone, or both.
- It is designed to be used on plants of varying size, up to a maximum of eight chillers.
How is your chiller plant bringing optimal savings to your overall energy cost???
Automated Logic® WebCTRL® add-ons extend the capability of the WebCTRL building automation system.
The Trend Export add-on allows you to specify, manage, and export trend data from the WebCTRL building automation system so that it can be analyzed externally using third party analytics packages or tools. Trend data can be exported on-demand or at scheduled intervals. This provides building operators with a simple and powerful way to view their important building data inside their visualization tool of choice.
Key Features and Benefits
• Common .CSV export format for the trend data ensures ease of use outside of the WebCTRL system
• Up to two years of trend data can be exported
• Daily, hourly, and on-demand export options
• Scheduled trend exports only include new historical data received since the last export
• Trend data can be grouped and scheduled for added flexibility
We are excited to announce the release of the WebCTRL® system Fault Detection and Diagnostics Phase II SAL
|Initially introduced with WebCTRL v6.0, the latest release of the Automated Logic Fault Detection and Diagnostics (FDD) library can now pinpoint over 100 proven faults in typical HVAC equipment, including VAV systems, air handlers, fan coils, unit ventilators, water-source heat pumps, and air-source heat pumps.
The logic for the equipment types listed below includes the following types of faults in the FDD alarm category
The logic in this library generates FDD alarms to warn users of problems which may be causing equipment to run inefficiently, wasting energy and/or degrading occupant comfort. The Department of Energy estimates FDD alarming could reduce energy use by up to 15%, and the State of California now requires FDD alarming in the Economizer section of certain rooftop units.
Examples of problems that this logic will detect include:
- Leaking Heating Valves: A worn valve seat or a misadjusted actuator can cause a heating valve to “leak” hot water to the coil even when it is commanded 100% shut. This wastes heating energy and can bring on additional cooling, which wastes cooling energy. The FDD logic generates an alarm if there is a significant heat rise across a closed coil.
- Failed DX stage: In a multi-stage DX unit, if one cooling stage fails, the controls will bring on additional stages as needed to provide the required cooling. The user will not even be aware of the failed stage until the weather gets really hot and the unit can no longer provide sufficient cooling without that stage. Then repairing or replacing that stage becomes an emergency. The FDD logic monitors each stage as it is commanded on, and generates an alarm if any one stage fails to provide cooling. Repairs can be undertaken on a routine basis, while the building is still comfortable.
- Continuous Running: For a typical building, one of the most effective ways to save energy is to make zones “unoccupied” and turn equipment off at night and over weekends when no one is using the building. Unfortunately, a common problem with building automation systems is the existence of “rogue” schedules, locked points, and other overrides which unintentionally cause systems to run even when unoccupied. These problems often go unnoticed because no one is in the building at the time. The FDD logic monitors zone runtime and generates an alarm if it exceeds a certain number of hours per day. By default the trip point is set at 23 hours, but it can easily be changed to a shorter time for zones that should only be occupied fewer hours.
