VFD Training Part 2: Tim Chamblee continues his Variable Frequency Drive training with an in-depth explanation of the application benefits, the potential energy savings, and the importance of proper grounding and wiring methods — and then demonstrates how to use a Honeywell Variable Frequency Drive to control a cooling tower fan with a Honeywell T775 controller.
Belimo’s Energy Valve is a strong favorite to win the 2014 Energy Savings Solution Product of the Year because of its incomparable engineering sophistication and bonafide performance that takes HVAC energy savings to the highest levels. Belimo is delivering the future of energy savings — today!
Overview:The Energy Valve is a pressure independent valve that measures and manages coil energy by using an embedded electromagnetic or ultrasonic flow meter, along with supply and return water temperature sensors. The Energy Valve also has the patented Power Control and Belimo Delta T Manager™ logics built-in that monitors coil performance and optimizes the available energy of the coil by maintaining the Delta T. In addition to the standard analog signal and feedback wiring, it communicates its data to the Building Management System (BMS) via BACnet MS/TP or BACnet IP. The built-in web server collects up to 13 months of data that can be downloaded to external tools for further optimization.
This week Stromquist hosted a Drive to Savings Day with Siemens and GA Power to educate our customers on the benefits of Variable Frequency Drives and GA Power’s current rebate programs for VFDs and other HVAC equipment. Most people already know that installing a VFD can save money by cutting back on the energy it takes to run equipment, but not everyone is aware that there are additional savings to reap by taking advantage of GA Power’s rebate opportunity. For any NEW drive installed on existing equipment, GA Power will issue a $50 per HP rebate. So a 20 HP drive will bring a $1000 rebate. Add that to the money saved in energy costs, and the new drive will pay for itself very quickly!
If you are in Georgia and would like to install some new VFDs, call Stromquist at 404-794-3440. We sell great, competitive drives from Honeywell, Johnson Controls and Siemens. We’d be happy to help you put some money back into your budget. Then maybe you can roll those savings into a new chiller that will also qualify for a GA Power rebate.

Authors Barney L. Capehart, PhD, CEM Professor Emeritus University of Florida and Michael R. Brambley, Staff Scientist in Energy Technology Development at Pacific Northwest National Laboratory (PNNL) have produced an HVAC Opus Magnus that will serve the entire spectrum of building and automation experts well — now, and for many years to come. Whether you’re a systems integrator, BAS or BMS Consultant, manufacturer or vendor, engineer, Director of Facilities or maintenance manager, this smart building tome (textbook) provides not only vital insight, methodologies, and options, but the compelling documentation that warrants immediate action.
Foreword: By Ken Sinclair Publisher/Owner, AutomatedBuildings. This book will help you explore the new world of Automated Diagnostics and Analytics for Buildings and provide insight and connection into the industry thought leaders that are taking big data into a new reality. “Dynamic Data Fuels Deep Analytics” speaks to the importance of the next level of deep analytics of almost everything will have and how we as an industry will provide a new level of deeper analytics connecting inquiring minds to almost everything with low cost real time data.
Introduction: The purpose of this book is to promote and document energy savings from the relatively new technology of Advanced Energy Information Systems called Automated Fault Detection and Diagnostics (AFDD) and Analytics for buildings and facilities. A number of studies have shown that commercial buildings in the United States (U.S.) waste as much as 15% to 30% of the energy they use (Katipamula and Brambley 2005). Analysis of HVAC and other building energy use data, along with whole-building utility data, sub-metered end-use data, and data from the building automation system (BAS) through the use of AFDD and building analytics can help identify opportunities to improve building operations and efficiency, and ultimately reduce energy and operating costs.
We will discuss the latest technologies available for fault detection, diagnostics, and building analytics, and operational experience with stand alone and web based systems for fault detection, diagnostics and analytics in currently operating buildings and facilities, and in varied applications, and to show how new opportunities have developed for energy and facility managers to quickly and effectively control and manage their operations more efficiently, with less energy use and cost, and experience improved energy system performance. You’ll find information on what is actually available using this technology, what products and services are available at this time, and how they are being used at other buildings and facilities, and see what is involved for current and future installations of internet-based technologies. The material in this book on automated fault detection, diagnostics and analytics should greatly assist energy, facility and maintenance managers, as well as consultants and control systems development engineers. Chapters on methodology and future technological features should also assist those involved in research and development of these new technologies in AFDD and analytics for buildings.

ControlTrends is delighted to share this informative expertise from Mike Welch, Managing Director of Control Network Solutions, founded in 1996, and headquartered in Basingstoke, Hampshire, UK (approximately 45 minutes from London). Mike is a DALI™ (Digital Addressable Lighting Interface) lighting control specialist and makes a compelling case as to why it makes commercial sense to adopt a more flexible, open approach to the control and management of lighting systems today.
At a recent RBS Innovation Gateway meeting, Professor Doug Crawford-Brown from the Centre for Climate Change Mitigation Research at Cambridge University spoke on the concept of ‘stranded investments’. A stranded investment is one where a particular technology or solution is acquired to address one set of issues. But, in the time it takes to implement the solution, the reality dawns that the situation has changed and a whole range of new issues have emerged which will not be effectively addressed by the investment made.
This concept applies readily enough to the way we construct and manage buildings. We spend huge amounts of time, effort and money in trying to plan for a building that will operate in a certain way before the foundation holes have even been excavated. When we arrive at the point of occupation, the world around us has invariably moved on. Business conditions, the environment, energy prices, regulations and other factors are rarely, if ever, fixed points for any considerable length of time. Occupier expectations of the spaces they inhabit have also changed and will constantly evolve over the lifetime of the building.
Of course, every building can be reconfigured to adapt to changing factors and user needs. But, this type of renovation often requires a fleet of trucks and an army of trades to put in new cables or remove existing ones; to move partition walls; fit new lighting fixtures and shift other equipment around. It’s a very labour-intensive and expensive process. But, it doesn’t have to be this way. Increasingly, we live in a world of soft, easily reconfigurable technologies, especially in the world of building controls. If the right technology decisions are made at the beginning of a project, then the building can be easily adapted to cope with the impact of office churn.
Take the recently completed Standard Bank office in Johannesburg as an example. In this prestigious building, some years in the planning, everything was delivered and installed according to specification. However, as soon as the building became occupied, reconfiguration took place very quickly. Many of the people moving into the building were not those initially consulted about their space requirements by the building’s designers. And, if they were, their views and needs had altered since that first consultation. A number had changed their job within the company or, fundamentally,wanted their desks in a different part of the workspace, so re-organising their space in a way that impacted on how the lighting was grouped, switched and controlled. Sending in specialist engineers to reconfigure the lighting could have proved a nightmare. Instead, on this project, change has proved a much more straightforward process.
This 65,000m² office development features an elitedali™ solution which is controlling, maintaining and managing the lighting system for the entire building, incorporating 4,500 Digital Addressable Lighting Interface (DALI®) light fixtures and 1,600 DALI® multi-sensors. elitedali enables Tridium’s Niagara AX platforms to provide the building with intelligent, automated dimming and switching off of lights in response to daylight and occupancy sensors to save considerably on energy consumption. It also speeds up maintenance, by reducing the time required to replace or reconfigure luminaires according to user demand. From the site or wherever they might have been in the world, the systems integrator has the freedom to simply access the wire sheets via their PC, then re-group, re-zone and re-adjust control strategies, as necessary. They could re-associate groups of lights with new switches and sensors, different numbers of lighting or whatever was needed to meet the new requirements of its occupants in real time.
This was all accomplished quickly, cost-effectively and with minimum impact on the actual business that the end client was trying to transact in the space. And, it’s a process that will inevitably continue to be repeated over the lifetime of the building.
The lessons are clear. In my view, we should simply resist trying to work out what’s going to happen with our buildings and its occupants in the future. It makes far better sense to implement solutions, such as those at Standard Bank, which maximise the ability of those tasked with managing or using that space to be as flexible as possible so that they can adapt to what is in front of them at minimum cost and as near as possible in real time.
An open approach brings the opportunity to realise these and other substantial benefits. I think of it as an inverted pyramid. With the pointed end at the bottom, we emerge through the pyramid, and, as it widens out, we find greater and greater opportunity to achieve more and more desirable outcomes – flexibility of reconfiguration, energy savings, reduced CO2 emissions, better value assets, improved building ratings, easier operation and maintenance, lower costs and so on. By bringing together elitedali™ lighting control and Tridium’s NiagaraAX Framework, energy managers can change the way the lighting operates and observe changes in energy use in real time.
They can also receive in-depth and accurate information about the performance of the lighting through the BMS as never before. Without such an open solution, it is only possible to access such data in a proprietary format, making it difficult to combine with data gathered from other areas of the building services. This approach puts that information directly into the clients’ hands, and enables them to specify the format of the information produced for “cloud analytics and big data” applications.
It’s a world that liberates energy managers and buildings owners and transforms buildings from stranded investments to valued assets.

Last year, commercial buildings consumed about 20 percent of all energy used in the United States at an estimated cost of nearly $180 billion, and are responsible for 18 percent of total U.S. carbon emissions.
The projects announced today will generate data, case studies, and information intended to help commercial building owners adopt new energy efficient technologies, including advanced ventilation, building energy use optimization software, more efficient commercial refrigeration fan motors, and advanced lighting controls. The selected projects include:
enVerid Systems (Houston, Texas) – enVerid will retrofit building ventilation systems with modules that remove indoor air pollutants such as carbon dioxide. This enables the indoor air to be recycled while greatly reducing the amount of outside air ventilated into the building and reducing the loads on the heating, ventilation, and air conditioning (HVAC) system. Facilities could experience significant energy savings with this retrofit technology. Ten separate commercial building demonstrations will be conducted over 3 years.
BuildingIQ, Inc. (Foster City, California) – BuildingIQ will optimize HVAC energy use across commercial buildings using Predictive Energy Optimization (PEO), a cloud-based software application that runs on top of existing building automation systems. PEO uses data from weather forecasts, utility tariffs, demand response event signals, and occupant schedules to automatically adjust energy-consuming building systems. These adjustments are based on building-specific modeling that PEO uses over time employing building use data, as well as predictive algorithms and advanced control strategies. Sixteen separate building demonstrations will be conducted.
QM Power, Inc. (Lee’s Summit, Missouri) – QM Power has developed high efficiency 7-16 watt fan motors that are often used in commercial refrigeration systems. QM Power intends to install and demonstrate approximately 12,000 high efficiency fans in more than 50 grocery stores throughout the U.S., focusing on open display case retrofits that could result in significant efficiency improvements. If fully adopted, the motor application has the potential to achieve more than 0.6 quads in energy savings and reduce energy costs by $1 billion.
Northeast Energy Efficiency Partnerships (Lexington, Massachusetts) – The project is designed to further the implementation of advanced lighting controls (ALCs), which turn off or dim lights when they are not in use. The project will demonstrate and evaluate two or more ALC technologies in 10 buildings, which should experience significant energy savings compared to a traditional lighting retrofit without controls. Designers and installers will be trained to use the technologies. The demonstration results will be used to support development of utility incentive programs to help further drive adoption of ACLs.
The Department’s Office of Energy Efficiency and Renewable Energy (EERE) accelerates development and facilitates deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality, and economic vitality.
