Fort Riley is a United States Army installation located in North Central Kansas is to install 300 Aldes ZRT-PDILs as well as several CAR3s to 3 of its barracks. Although construction is not projected to begin until spring, behind the scenes work has been taking place for months.

The three barracks in this phase of renovation have long histories! All were built in 1970 and have undergone minor renovations over the years. While the HVAC systems and some interior components were repaired in 2006, one has sustained major damage from a lightning strike while the other two stopped housing Soldiers back in 2018. (1)  Although the structural changes are important, the main motivation behind the project is to boost the soldiers’ morale and to offer them a healthy and enjoyable living environment.  “It’s not just about the requirements. You also have to consider colors, materials, everything that’s going into the rooms – because all that can change morale” said Brett Deam, architect, Engineering Services Division. The master planning team agreed that the morale of the Soldiers is a huge consideration when they create their design plans. “Really, the goal of our mission is to boost morale and provide better living conditions for these soldiers” said Blanchard Brown, engineering technician, Master Planning Division.

Aldes Parallel Damper In-Line Zone Terminals (ZRT-PDIL) are designed to introduce flexibility and dynamic control to central supply or exhaust ventilation systems. Used in both large and small systems, the ZRT-PDIL regulates ventilation without the need for individual fans or traditional VAV terminal units.

Each ZRT-PDIL is a two-position, pressure-independent terminal with a control damper to regulate high limit on-demand airflow control and integral passive regulators for automatic air balancing of the continuous and boost airflow setpoints. This unique combination provides flexible control schemes without the need for expensive pneumatic, electronic, or DDC control systems.

The ZRT-PDIL is primarily used for combination low-flow indoor air quality ventilation or make-up air, and on demand high-flow spot ventilation using the same central exhaust or supply fan system. This is achieved by integrating a minimum Constant Airflow Regulator (CAR) in the terminal end panel and in-line with the branch duct. The maximum airflow is controlled by a series of 24 VAC or 120 VAC powered motorized damper(s) and a secondary CAR airflow controller. With the maximum-air motorized control damper completely closed, the continuous CAR allows steady, low-volume airflow control (Continuous and Boost Constant Airflow Regulators may be CAR-II or CAR3 depending on required airflow).

VENTILATION: how to protect yourself against COVID-19

Is opening windows enough to fight the virus? Does the virus spread more easily with ventilation?

This year ventilation has been a topic of conversation in households across North America. ALDES is here to provide clarity and answer your questions!  A specialist in indoor air quality, ALDES sheds light on what you need to know about the importance of ventilation in light of COVID-19.

Opening windows is sufficient in removing the SARS-CoV-2 virus.

FALSE. Opening windows is easy to do, but it is not enough because it helps to dilute the concentration of the virus only while the window is open. Opening windows can also have negative thermal and acoustic impacts as well as poor air quality when the outside environment is polluted. It must be supplemented by a mechanical ventilation system (CMEV) to ensure a continuous and controlled renewal of air, so as to avoid an accumulation of CO2. A high concentration of CO2 reflects poor ventilation and may therefore contribute to the spread of the SARS-CoV-2 virus. (1)

Mechanical ventilation reduces the risk of transmission.

TRUE. Mechanical ventilation reduces the risk of transmission of the virus by a factor of 10. (2) It is safe to say that a well-ventilated room lowers the risk of transmission and is better for your health.

The SARS-CoV-2 virus can live several days suspended in the air.

FALSE. The virus is spread either by droplets or by airborne microparticles. It can stay several hours in suspension. Maintaining ventilation is therefore essential for renewing the air and preventing the virus from remaining airborne. (3)

Once captured by the filter, the virus dies.

TRUE. The filter will not let the virus escape and go through the ventilation system – Once captured by the filter, the virus dries and dies by itself. (4)

The use of stand-alone air purifiers in a room is enough to free the air from the virus.

FALSE. An air purifier does not renew the air. It is a good complement to mechanical ventilation, which constantly renews the air, treats other indoor air pollutants and thus meets regulatory ventilation standards.

Older buildings do not have ventilation solutions to renew air.

FALSE. There are different mechanical ventilation solutions available and suitable for refurbishment, which guarantee a continuous renewal of the air in each room of the home. An older building does not mean that the ventilation system is inadequate. (5)

Luxury Energy-Saving Hotel on La Salle Street in Chicago to install ALDES ZRT® & CAR3®

 

The Reserve Hotel, part of the Marriott’s Autograph Collection, is a 234-room hotel named after the Federal Reserve Bank next door. This sumptuous hotel is under construction and supposed to open late next year (2021) on floors 18 through 22 of the historic former Continental Bank building. The construction will include 250 ALDES Zone Register Terminals (ZRT®) and 228 ALDES Constant Airflow Regulators (CAR3®).

Developers of the Reserve Hotel have qualified for $21.25 million in financing for energy-related work designed to lower costs over time. The financing is the first project approved by the Chicago PACE, or Property Assessed Clean Energy, a program the Illinois General Assembly authorized statewide in 2018. The first 12 stories of the Continental Bank Building are already occupied by the JW Marriott Hotel. The CEO of the Prime Group, the developer of the Reserve Hotel, wagered on demand for a luxury hotel in the heart of the city’s financial district back in 2010 when he helped develop the JW Marriott Chicago. This grand project also involves W.E. O’Neil Construction as well as Chipman Design Architecture, and HVAC design/build by Advance Mechanical Systems.

This sumptuous project will include 250 ALDES Zone Register Terminals (ZRT®)  which are designed to introduce flexibility and dynamic control to central ventilation systems. Used in both large and small systems, the ZRT regulates ventilation without the need for individual fans. In addition, 228 ALDES Constant Airflow Regulators (CAR3®) will be installed before the opening of the hotel that is set to open sometime next year. For this project, the ZRT® and CAR3® are outlined to be installed for toilet exhaust in guestrooms to ensure constant airflow and minimize stack effect. The ZRT®-S will be tied into the room occupancy sensors making sure fresh air is provided when necessary, ideal for a hotel. Each CAR3® is built in the U.S. using a proprietary blend of amorphous thermoplastic resin treated with antimicrobial, anti-static, and flame-retardant materials to provide reliability and longevity. The CAR3® is calibrated to respond to changes in pressure with no input from an external power source or signal. Each CAR3® is also available in a variety of assemblies to provide a complete solution.

Ventilation and COVID-19

At Aldes, healthy indoor air is not just what inspires us, it is what we deliver.  During these past few months of the COVID-19 crisis, we have all listened as infectious disease experts have attempted to provide answers to innumerable questions surrounding the transmission of the virus.

Many of those questions are from homeowners and building maintenance managers wondering how to reduce the spread of COVID-19 within a building or home using their HVAC system.

An abstract of a study published recently in the journal of Respiratory Medicine, The Lancet, links mechanical ventilation with a dramatic reduction in the time that droplets containing COVID-19 stay airborne in a room.  The more air exchange that an area gets, the less time particles remain in the air at mouth-level where they can be transmitted from person to person.  The study shows that in a well-ventilated space, the average time for half of the particles to fall is 30 seconds, whereas in the same space without ventilation, the time is over 5 minutes – that is 10 times longer!

Knowing this, to help keep yourself safe if you are in close proximity to someone who may have  COVID-19, it is very important to ensure that your ventilation system is operational and well-maintained.

If you have an HRV or ERV:

  • Ensure that the filters are clean.
  • Remove any blockages in the intake and exhaust grilles on the outside of the building.
  • Set the HRV to air exchange mode. High speed will bring in more outdoor air and move the air faster.
  • Do the “tissue test” at the air supply and exhaust grilles to ensure that air is flowing. Take a tissue and hold it up to the grille. It should quickly stick to the exhaust grilles and quickly blow away from air supply grilles.  If the tissue test shows no airflow at one or more grilles, contact a ventilation contractor.
  • Keep inside doors open at least slightly to allow air to flow freely in and out of the ventilation system.

Remember, the important thing is for the “bad” air to be replaced by fresher air.  Do not use ceiling fans or pedestal fans that recirculate air within the same room – in fact, these can be even worse than having no ventilation at all!

Finally, opening a window is always a great way to increase the air exchange when weather permits.

Aldes is at the forefront of Healthy Living – delivering fresh air to occupants of all buildings, for health, well-being and a better life for all of us.

Enhancements to our Light Commercial Heat and Energy Recovery Ventilators

Deliver Healthy Air and Optimize Efficiency with Variable Speed Ventilation!

  • 0-10V inputs to continuously adjust the speed of the H/ERV. No more over- or under-ventilating providing the optimal amount of fresh air for any occupancy situation.
  • Wire the H/ERV directly to the building electrical main using our terminal block – no more power cords with plugs that need a separate electrical box to be installed.

Aldes is pleased to announce our Light Commercial H/ERVs can now be wired for continuously variable ventilation using one or two 0-10V inputs (one for the supply motor and one for the exhaust motor) which works with both EC and AC motors.  Or, you can still wire the units with the 24V dry contacts as well as Aldes wall controls – both options are supported on the same H/ERV.

In addition, all the H/ERVs now have a terminal block for the power connection, instead of a power cord with plug.  This makes it easier and saves the electrician time wiring the system to the building’s power supply and complies with electrical codes in North America.

The new models have new part numbers, to distinguish them from the previous units.  The new model numbers are the same as the old ones, with the addition of “-N”. For example, the E650L-Fi-EC becomes E650L-Fi-EC-N.

In addition, the -Ri models for recirculation defrost are no longer available. To order H/ERVs with recirculation defrost, simply add the appropriate recirculation kit to the order:

P/N 683900: Recirculation defrost option for 650 models

P/N 683950: Recirculation defrost option for 1100 models

P/N 683960: Recirculation defrost option for 1800 models

The existing models with power cords will continue to be available until
June 30, 2020.
Please do not hesitate to contact Aldes with any questions.
