Don’t Shoot The Messenger! Let’s spread the word that achieving and maintaining ultra-efficient building energy system operation is possible, but to do so requires change.
Smart Grids Start With Smart Ideas Developing smart electric grids requires smart ideas and our industry can be a valuable contributor in developing them!
Getting There From Here Here is my list of areas that need our help with fresh thinking for new directions for us to get out of the rut we’re in.
State of the Industry - 2009 If you really want to help move our industry toward a future that works, I invite you to join with those who want a more sustainable future.
Obama’s Energy Challenge The building sector is described by incoming administration insiders as a core element of their new energy independence and global warming initiatives.
The Enemy Within Project engineers must be ready to give up the detailed design work with which they are familiar and provide the flexibility, support, and oversight to others so they can ensure ultra-efficient performance is achieved and maintained over time.
Making Sense of it All Automatedbuildings.com has not only provided those ideas and contacts for potential partners, products and procedures to help us push our network based energy efficient strategies forward, but it has also played an important role in developing the community of industry professionals.
Creating a Sustainable Building Industry Future Our industry needs to show in the new buildings we construct that achieving ultra-efficient building operation need not be a convoluted, expensive, or hit-and-miss process.
Two Critical Steps Toward Sustainability (That we need to take now!)
An Open Letter to the Clinton Climate Initiative It isn’t just a few who want this Initiative to succeed. All of society wants it to succeed and is watching us to see if we can work together well and hard enough to be certain it will!
Our Industry's Violent
And How to Move Forward Toward a More Efficient
Sustainable Buildings Are Industry Groups The Solution or the Problem?
Making Energy Efficiency Accountable Right now there is no off-the-shelf delivery process in place to develop truly effective energy efficiency improvements with long term performance assurance.
The Consensus Conundrum To be successful in your contribution to this industry at this critical time, more than anything else these good ideas you develop need an effective champion – you!
What does it Really Take to be an Intelligent Building? To get our industry to meet its commitment to owners, occupants and the rapidly evolving energy and environmental performance expectations of our society, we need the connectivity we incorporate into intelligent buildings to add valuable function.
The Electric Utility Industry - Missing the Boat on Conservation Utilities’ business model – dictated to them by their regulators - is tied to selling electricity, not saving and redistributing it.
Moving Toward A Sustainable Building Industry A sustainable building industry will not only require new technologies, but also a vastly improved process for designing, constructing, and operating buildings.
The HVAC Industry CAN Reinvent Itself! There is a growing understanding that there will come a point in human history at which society has to learn to continue its progress while it reduces its consumption of resources. That time may be very near.
Can ASHRAE Reinvent Itself? “We’re ready, and we’re waiting! Which is it?”

Design Team Communications: Keeping a Perspective on Personalities Don't ever let team members' personalities override the technical merits of any design development.
Applying Advanced Technology Products and Services to Projects The Process is the Problem!
Ending the Blackout Blues We need (REALLY need) to improve the way our industry delivers more advanced technologies to our building construction projects.
"IT" Could be the Start of Something Big Now, with the growing use of building networks and the convergence of building controls and IT networks, it is becoming far easier to connect building occupants to the building control system by employing a simple "comfort and lighting" icon on each occupant's PC.
Convergence - Engineered Systems April Outsert

Moving Forward! Are We? Will We Soon, or Ever? I predict a very strong movement to "occupant integrated" HVAC controls within the next decade.
Optimizing All-Variable Speed Systems with Demand Based Control To ensure that the full measure of savings is achieved, new methods of control along with the new all-variable speed equipment configuration must be incorporated into the design.
All-Variable Speed Chilled Water Distribution Systems: Optimizing Distribution Efficiency In many large cooling systems, the chilled water distribution system poses a much more immediate problem to overall cooling system performance and efficiency.
All-Variable Speed Centrifugal Chiller Plants: Can We Make Our Plants More Efficient? Why the sudden change in attitude toward variable speed?
Ultra-efficient LOOP Chilled Water Plant Control At Bellevue Corporate Plaza LOOP control manages valve opening and pump speed to automatically maintain minimum flow at all times a chiller is in operation.
TECHNOLOGY SUPPORT: A Critical Issue in Industry Restructuring How these issues are best resolved are determinations that will be made by those who most successfully navigate the uncharted sea of industry restructuring.
Occupant Connectivity for Building Controls The development of low cost wireless data transmission technologies demands a new look at how building control systems can effectively employ such technologies.
Steps to a More Efficient Chiller Plant a follow up article to the January 1st article "Improve Chiller Plant Efficiency" describes the steps I recommend to improving chiller plant efficiency in response to several readers who asked me that question.
Improve Chiller Plant Efficiency! My preferred solution is to design and implement a simple and economical chiller plant control network for the chillers, pumps and tower fans, that automatically operates and sequences all equipment to meet the load and optimize efficiency.
Designing Greener Buildings ".....the target audience for greener design should start with the building development and property management community."
The "Comfort Industry" A 21st Century Opportunity This new commercial building comfort industry will market to tenants, and products will be installed by office furnishing installers, not building trades.

BAS and EGB and the State of the Industry It’s clear that in the last year our clients and society in general has moved much further in their expectations for sustainable buildings than this industry has moved in our ability to effectively implement them.
The State of Sustainability All of us need to ready ourselves to participate in projects wherein we can assure that sustainable principles are really applied so that energy use and resource depletion are truly reduced by orders of magnitudes.
What’s Relational Control? What can you tell us about this control technology and why it deserves a special name.
Web Based Facilities Operation I like Web Based remote access because it offers the opportunity for uniform access to systems of many different manufacturers. I would be hard pressed to remember how to access some of the older projects because each dial-up connection uses one-of-a-kind proprietary access procedures. Web Based access promises to develop into a much more standard and universally accessible interface.
"Open" Building Control Systems We need to avoid participating in the current protocol wars that are much ado about very little, and focus on what will really help make the system you are designing open for the needs of your client.
The Effect of New Control Technologies on Sensor Selections - November 2001 Demand based control is a lot simpler than conventional control and can reduce the size and complexity of the HVAC systems, but a basic change in how the system is operated has to be made first to achieve this simplicity of configuration and operation.
