Building owners are often faced with decisions that carry either heavy consequences or sweet rewards and regardless of the function of a building, nine times out of ten it will need air conditioned space in some form or fashion.  Because of this inevitability the decisions one makes in regards to their HVAC system can have a substantial impact on the financial landscape of their business and becomes even more prevalent the larger the footprint of the building.  Either way, regardless of the size of the building, it is vital to make smart decisions regarding your HVAC system and Building Automation System.

Whether you are wearing “The Golden Handcuffs”, as I wrote about in a previous article, or you have a dying pneumatic system that desperately needs to be upgraded, there is a way to accomplish this daunting and sometimes intimidating task without sinking the ship financially.  I call it “The Slow Play”.  All too often building owners will be led to believe that they need to “Rip and Replace” their entire control system in one fail swoop in order to make the necessary upgrades.  This simply is not true.

With our Tridium Niagara offering we can migrate an entire HVAC system one piece at a time without interrupting the operation and functionality of the existing system.  Being able to offer this to our customers allows them to preserve precious cash on hand while still moving forward with the renovation.  For example, let’s look at a building with ten Air Handlers, sixty VAV boxes, two Chillers, two Boilers and five Exhaust Fans.  While there are endless as well as differing combinations of equipment from building to building, this example will at a minimum, allow us to step through “The Slow Play” process.

First, we will integrate the Chillers and Boilers because the majority of the other equipment in the system hinge on the functionality of these two vital pieces of equipment.  After we have the Central Plant equipment under control we will turn to the Air Handling Units.  The VAV boxes that are served by each Air Handler need to be identified because we will be integrating those boxes along with the Air Handler as one single system.  For example, AHU-1 serves VAV boxes 1 through 6 so for this phase we will only be integrating those pieces of equipment.  We will continue in this fashion until all of the AHU’s and VAV’s have been converted.  After we have all of the major equipment rolled over to the new system it is fairly easy to move over the rest of the auxiliary equipment in the building such as exhaust fans, lighting panels, etc.

Typically, this work will be done after hours, on weekends, or at a time that has the least amount of impact on tenant space comfort.  Some building owners may choose to implement each phase on a monthly basis, quarterly basis or even a yearly basis.  Regardless of the time period they choose to spread it out across, the value lies in the ability to not only methodically integrate the entire system without interrupting existing functionality, but most importantly, break out the cost of the new system into manageable amounts.

Here at HTS we are not interested in leading our customers down a path that only benefits our interests and our goals, but rather a team approach that benefits everyone involved and builds a relationship that both parties can rely on for years to come.  So if the fear of cost is holding you back from upgrading your Building Automation System then give HTS a call and let’s tailor your very own “Slow Play” gameplan.

You are a building owner and you have just bought a new Building Automation system for your building. Promises of energy savings, higher efficiency and lower maintenance costs were a major factor in your decision to upgrade your building. You have seen the studies and reviewed the data extensively and are confident that you made the right decision. All you can think about is how much money you will save on your energy bill due to your recent purchase.

While all of these claims are accurate and there is definitely tremendous value when investing in an automation system there is one caviot that building owners often overlook. While most prudent business owners will factor in the cost of maintenance and service, they often discount the lack of flexibility this new relationship offers or are completely unaware of what waits around the corner.

For many years controls contractors used what is called a proprietary protocol. Before Bacnet and Lonworks and even still today, each company had their own communication protocol that made it impossible for anyone else to service the system. You HAD to use the company that installed the system. This meant that the owner was now at the mercy of the installing contractor. You need a $10 part replaced? Sure that will be $2,000 for us to come replace it. You need a $200 board replaced? No problem – that will be $4,500. And let’s not forget the blistering speed of technology. You need a software upgrade – a function that literally takes a technician a couple clicks of the mouse and 10 minutes to execute – that will be $5,500.

The great deal that you got on your new Building Automation system that, according to the smooth talking salesman, “pays itself off within 3 years and lowers your electric bill and makes your building run more efficiently” is now costing you an arm and a leg to maintain and service. Not to mention you can’t get a technician to come fix anything in a timely manner. “We have you in the Q and we will dispatch a tech as soon as one comes available” is what they tell you. So not only do you have to pay outrageous service fees but you have to limp along until someone can actually come fix the problem.

This scenario is all too familiar to many building owners across not only Texas, but the entire country. We call this “The Golden Handcuffs”, and when you get Golden Handcuffs put on you they are very hard to take off.

TridiumHTS has heard your cries for help and we have a solution that puts the power back in your hands. The days of being a victim of your building automation system are over. We offer a completely open protocol system that not only matches up to the proprietary lines but far exceeds their functionality and flexibility. The Tridium Niagara front end gives the luxury of choice back to the customer and with over 300 drivers available we can seamlessly integrate any system. The days of paying $2,000 for a sensor are over. No matter how tight they may have put the golden handcuffs on you, we can take them off.

So give HTS a call because we have the key to the “Golden Handcuffs”!

If you’re trying to create the ultimate climate-controlled environment in your office, school, or healthcare facility, the Daikin Magnitude® magnetic bearing water cooled chiller is designed to help you accomplish that! Available from 100 to 1500 tons, the Magnitude chiller offers money- and energy-saving benefits for building owners and property managers, as well as a comfortable environment for building occupants.

mag-floorspace

Industry leading part load energy savings: Energy costs are rising, and efficiency is becoming a top priority for building owners everywhere. Saving energy means saving money, and when it comes to saving energy, Magnitude is up to 40% more efficient than standard centrifugal chillers and can save up to $4 million over the life of the chiller.

World-class, sustainable, and reliable performance: Daikin designed the magnetic bearing compressor to improve overall performance and reliability. The single rotating compressor shaft levitating on a magnetic field eliminates mechanical seals, wear surfaces, gears and slide valves so machines last longer and run better. Magnitude is world-class in performance, sustainability, and reliability across many commercial building applications.

Environmental commitment: Magnitude units exhibit commitment to the environment through the use of environmentally-friendly R-134a, a refrigerant that has no ozone depletion and no phase-out schedule. Magnitude also helps the environment with its oil-free design, high efficiency, and efficient use of materials, so you can help deter global warming while keeping your building cool.

LEED® points and potential rebate qualifications: Magnitude units contribute to LEED points and in some cases, help owners qualify for responsible energy use incentives and rebate dollars. The compact size also makes the Magnitude chiller ideal for retrofit and replacement products, as the unit can fit easily through standard sized doors, making it a perfect fit for your energy upgrade projects.

Oil-less technology allows maintenance savings: By creating a design that uses no oil, the Magnitude eliminates oil management systems for improved compressor and system reliability. The oil-free design also prevents oil contamination of heat-transfer surfaces, resulting in higher efficiency.

chiller

Overall, the Magnitude offers a great value and fast payback opportunity. In addition to energy efficiency, Magnitude magnetic bearing chillers have fewer moving parts, require no oil, nor oil-circulation equipment, and therefore require less maintenance and service to save you time and money.

Leading the way with LED

Lighting is one of those costs that every operating building incurs. As such, it is a great starting point for your next energy efficiency upgrade or renovation project.

With the up-front costs of LED products steadily declining, switching your lighting to an LED system is a cost-effective solution that can provide payback in 2-3 years at the earliest. While many energy-efficiency plans can take up to 15 years to see payback, this seems almost instantaneous.

LED lighting alone can cut your energy bill down, but when paired with a controls or smart lighting system, it can lead to 90% in energy savings.

A controlled lighting system works great for:

  • Buildings with fluctuating populations such as schools or office buildings
  • Warehouses and manufacturing facilities that require high lighting during working hours and little-to-no-light after hours
  • Arenas and expo centers that have several different kinds of events that require specific lighting

Energy efficiency. Sustainability. Green building. You’d be hard pressed not to come across these and other energy buzz words in the construction industry nowadays. This movement may seem modern, but did you know that water-source (or geothermal) heat pumps – one of the most efficient system options on the market – have been in use since the late 1940s?

For extreme climates like Texas, the water-source heat pump (WSHP) was a much needed solution to the traditional air-source heat pump system. Rather than using the outside air as the exchange medium, WSHPs use either geothermal heat or water tempered by a cooling tower/boiler. Either application uses a more constant temperature source. This creates less work for the system to output a comfortable temperature, resulting in major efficiency gains. While the technology has been around since the 1940s, vast improvements in the last 25 years have made the WSHP a viable option for all types of facilities.

Because of their use of individual units, WSHPs provide great flexibility in design. The zoning ability makes them a great fit for schools and multi-family buildings, as well as offices and hotels. Government projects also see great benefit in WSHPs as they can help meet energy requirements and contribute to LEED credits. Facilities with existing water features, like a pond, can often save money on WSHP installation as the water can be used as the heat exchange medium, rather than digging a trench to reach the earth or using a cooling tower/boiler. The durable construction of WSHPs gives them an estimated 25-year lifespan, and end-users can expect to see significant paybacks in 5-10 years.

Daikin water-source heat pumps can save energy, while also reducing design, installation and operating costs. Here is a breakdown of the benefits for all the involved parties of a project:
