Upper East Side, 83-unit Luxury Condominium Residence to Include Aldes Products

New York City’s Upper East Side is known for its luxury high rises, stylish boutiques, and upscale restaurants. One of newest additions is The Kent, an elegant 30-story, 83-unit condominium residence just a few blocks from Central Park. Among the amenities are an indoor pool and sauna, fitness center, sound lounge, canine spa, and zoned ventilation with centralized heating and cooling systems that include American Aldes Zone Register Terminals (ZRTs) and Constant Airflow Regulators (CARs).

Aldes ZRTs provide on-demand boost airflow, typically used in bathrooms and laundry rooms to exhaust humidity and odors. Aldes CARs automatically regulate airflow in duct systems to constant rates. These ZRTs and CARs are frequently the preferred ventilation products for multi-family buildings such as apartments and condominiums for simplicity and performance.

Architect Beyer Binder Belle has offices in New York City and Washington, D.C. and have been involved in such high profile projects as Grand Central Terminal, Rockefeller Center, the Apollo Theater. New York-based Interior designer Champalimaud has won awards for projects across the globe. Developer Extell’s full service real estate development team has nearly three decades of experience in New York and beyond.

The Kent topped out earlier this year and is expected to be complete in early 2018. The two to five-bedroom condominium residences are expected to bring $2.4M to over $20M each.

Aldes ZRTs and CARs have been installed in hundreds of apartments, condos, and other multifamily buildings across the United States and beyond. In New York City alone, manufacturer’s representative A.D.E. Systems has facilitated the sale of Aldes products in The Enclave at Cathedral, Citizen 360, 53w53, 520 Park Avenue and many others in the Big Apple.

Nearly 1,000 Aldes airflow & zone control products to be installed in The Legacy Minneapolis

Take a drive along the Mississippi River in the Mill District of Minneapolis and you’ll see one of the city’s largest developments underway, The Legacy Minneapolis. The 374-unit condo development borders Gold Medal Park and is spread out over 3 connected sections; a 14-story tower, and 8-story tower and a 17-story tower. The staggered design is intended to visually separate what would have otherwise been one large tower per the original building plans. Inside, American Aldes Zone Register Terminals (ZRT) and Constant Airflow Regulators (CAR) will help maintain energy-efficient, effective airflow throughout the building to each residence.

Aldes ZRTs provide on-demand boost airflow, typically used in bathrooms and laundry rooms to exhaust humidity and odors.  Aldes CARs automatically regulate airflow in duct systems to constant rates. These ZRTs and CARs are frequently the preferred ventilation products for multi-family buildings such as apartments and condominiums for simplicity and performance.

Shamrock Development—the company spearheading The Legacy Minneapolis—is no stranger to the city. Shamrock has developed over 5,000 lots over the past 30 years throughout the metropolitan area, with the late Jim Stanton at the helm. Mr. Stanton passed away in June, 2017. The building has been designed with an eye to providing residents with common spaces and a sense of community, including roof terraces, exercise space, a dog run, rain garden, pool, spa, roof deck with lawn bowling, fire bowls and gas grills. It is expected to open in fall 2018.

Aldes ZRTs and CARs have been installed in hundreds of apartments, condos, and other multifamily buildings across the United States and beyond. In Minneapolis alone, Aldes products have been installed in JW Marriott Minneapolis Mall of America, Pentagon Apartments, The Bridges, Radisson Blu Minneapolis, 4 Marq and others.

5 Effective Ventilation Solutions for Condos & Apartments

Shared walls, air balancing, energy efficiency, stack effect, changes in local code…engineers face these challenges and more when designing centralized ventilation systems for multi-family dwellings. It’s no easy task to comply with codes and regulations, plus satisfy building owners and developers. American Aldes and our manufacturing representative partners have worked alongside engineers for nearly 35 years designing cost-effective solutions that are easy to integrate into designs, install, and maintain. Here’s a look at five popular solutions from Aldes that’ll help you design ventilation systems for apartments and condominiums without the headache.

  1. The most configurable line of split-system Heat and Energy Recovery Ventilators with sizes up to 10,000 CFM. Each unit is built to your specifications, with multiple core options, duct configurations, supplemental heating and cooling, economizer controls, and they’re AHRI Certified. HRVs and ERVs exhaust stale air and humidity from buildings and bring in fresh air while maximizing energy efficiency and reducing the load on heating and cooling systems.
  2. Constant Airflow Regulators (CAR-II) correct stack effect by automatically adjusting to the changes in static pressure, so energy is not wasted and optimum air quality is maintained. CARs don’t require any electric or pneumatic sensors or controls and are a low-cost solution for balancing ventilation systems, eliminating the need for on-site balancing and repeat maintenance, keeping the system running at optimal performance year-round. These are perfect for new construction or retrofit projects.
  3. Zone Register Terminals (ZRT) provide energy saving demand control, self-balancing ventilation without the need for individual fans in bathrooms or other high humidity areas. They provide up to four different control schemes without the need for pneumatic, electronic or DDC control systems. Parallel Damper In-Line Zone Register Terminals (ZRT-PDIL) also replace individual fans or VAV terminals, and provide combination low-flow indoor air quality ventilation and on-demand high flow spot ventilation using the same central exhaust or supply fan system. The ZRT-PDIL is your simple solution to provide makeup air for equipment like kitchen range hoods, or demand based ventilation for high volume applications.
  4. Constant Exhaust Registers and Constant Supply Registers (CERs and CSRs) combine the constant airflow regulators (explained in #2 above) with an exhaust or supply grille constructed of heavy-gauge extruded aluminum. Airflow rates are factory set based on what is specified, and are quickly installed like any grille, so no additional labor is required. Need one of these with a fire damper? We’ve got it. Constant Exhaust or Supply Registers with Fire Dampers (CER-FEA or CSR-FEA) regulate airflow and include a grille and a two-hour rated fire damper.
  5. Constant Exhaust Grille (CEG-II) automatically regulates airflow and can be adjusted to distinct pre-calibrated airflow settings, making it easy for the contractor to make on-site adjustments if ventilation demand changes.

If you’re thinking that looks interesting, but how do I know it works well? Don’t just take our word for it. Visit our project map to see a small sampling (and by that we mean hundreds!) of multi-family buildings across the nation that have recently installed these products and others.

Aldes has a full lineup of products for centralized systems, but if it’s unitized/compartmentalized you’re designing, we have cost effective, energy efficient systems for that too. In fact, we’ve got compact sized heat and energy recovery ventilators perfect for apartments or condos, and ENERGY STAR rated fan small enough to fit into tight spaces.

5 Benefits of De-Centralized Ventilation in Schools

Compare the number of students in a typical classroom to the number of employees in the average office space of the same square footage and you’d find the density in schools is 3 times higher. Bringing in the proper amount of outdoor air and delivering it to each space efficiently can be a challenge. Couple that with the varying uses and activity levels of each classroom and there can leave a high potential to save—or lose—ventilation costs on each classroom. De-centralized ventilation systems, in which each classroom or zone can be managed separately by a light commercial heat or energy recovery ventilator, can have some big benefits. Here are a few worth considering.

  • Demand-based ventilation. Classrooms may be filled with students from 8 am to noon two days per week, and full the entire school day on the other three days. Rather than running at full ventilation rates on all 5 days, districts save money by ventilating only on the days and times it’s needed.
  • Flexible maintenance schedule. De-centralized ventilation systems use smaller heat or energy recovery units that can be maintained without shutting down ventilation to the entire building; only the classroom or zone it manages. Facility staff can plan on performing maintenance during the school day when students are at lunch or other activities.
  • Simple to control and balance. It’s simple to implement a control strategy with light commercial heat or energy recovery ventilators since the system is not dependent on VAV systems. Even better, since the ventilator is dedicated to one classroom or zone, there are no long duct runs, and balancing is quick and easy with only 1 (or a few) connection(s) per fan versus central systems which may have dozens of connections per fan.
  • Convenient access. Select light commercial heat or energy recovery ventilators are small enough to fit above drop ceilings, so they can be accessed easily without the liability and weather-related challenges of accessing a rooftop or dedicating space in a mechanical room.
  • Improved motor performance. All American Aldes light commercial heat or energy recovery units have direct-drive backward-inclined motors for improved performance and reduced maintenance since there are no belts to maintain or change.

Only Aldes makes light commercial heat and energy recovery ventilators with plate-type exchangers rather than wheels, so there’s no moving parts and they easily slide out for cleaning; dual side access doors for building maintenance staff to service the unit from either side; and multiple speed blowers built into the unit controls as a standard feature. Aldes light commercial series are simple to install and require no special wiring, just plug them in.

While de-centralized systems have plenty of benefits, some districts may prefer centralized systems. Either way, Aldes has solutions with a wide range of heat and energy recovery ventilators just right for schools, from 650 CFM all the way up to 10,000 CFM. In fact, schools across the country are choosing a variety of Aldes HRVs and ERVs for their durability, energy savings, low maintenance, and competitive pricing. Learn more at www.aldes.us/schools.

American Aldes and HTS Texas Secure Sale of 173 Commercial ERVs in Prestigious School District

American Aldes’ and their North Texas representative Heat Transfer Solutions (HTS) of Texas has secured sales of 173 Energy Recovery Ventilators serving four schools in the Frisco Intermediate School District.  Frisco, Texas is located just north of Dallas, and is one of the nation’s fastest growing cities in the United States, coming in fourth with a population growth of 6.3% between 2014 and 2015 according to the U.S. Census Bureau.

The Frisco Intermediate School District is also undergoing tremendous growth with thousands of new students coming into the school district every year.  Business expansion and corporate relocations to the area, resulting in new jobs in several sectors and a boom in residential housing have contributed to population growth and the need for more schools.

To accommodate the growing student population, the district is adding several new schools across four campuses. The E650 and E1100series light commercial energy recovery ventilators are being installed in the new Memorial High School (85 ERVs); Lawler Middle School (36 ERVs); Tally Elementary School (26 ERVs); and Liscano Elementary School (26 ERVs).

Part of the challenge was adapting the standard light commercial ERVs to meet some unique design criteria found in each school.  It required a collaborative effort between the American and Canadian Aldes teams to quickly make the changes necessary in order to secure the projects.

Aldes’ representative HTS is the largest independent commercial HVAC manufacturers’ representative in North America. The company represents more than 100 HVAC suppliers and has close to 600 employees in 16 cities across Canada and the United States.

“HTS recognized the opportunity to provide these schools with Aldes energy recovery ventilators that will save the district on energy costs and provide healthy indoor air for thousands of students,” said Tom Heidel, National Distribution Sales Manager at American Aldes. “We are pleased that HTS continues to be aggressive in securing specifications and sale for our air exchangers and look forward to future growth with HTS.”

Marriott Hotels Save Energy with American Aldes ZRTs

Marriott is well known among business and leisure travelers for providing an exceptional guest experience. As the world’s largest hotel company, Marriott International, Inc. has nearly 6,000 properties in 120 countries and territories. Engineers designing Marriott hotels understand that poor ventilation, odors, and discomfort can quickly erode the guest experience and have committed to ensuring proper ventilation.

This document gives a high level overview of the pilot project in which American Aldes provided proof of concept to Marriott, resulting in energy savings and healthier indoor air quality for all new Marriott properties through the use of American Aldes Zone Register Terminals® (ZRT).

Common air quality and inefficiency problems in hotels
Among hotels nationwide, millions are spent covering up unpleasant odors. Trouble-shooting and balancing ventilation systems can be time consuming and costly. Guest control of the ventilation (bathroom fans) is unreliable and creates pressure variations between rooms, increasing cross-contamination risk.

Even in continuously operating central systems, where the hotel is in control of ventilation, many factors still impact the effectiveness of ventilation, including stack effect, wind effect, and poor ventilation system installation and maintenance. Compounding the inefficiency problem is the variable occupancy conditions. Even when a hotel is at full capacity, studies show that rooms are only occupied 72% of the time; guests are at local conferences, meetings, or vacation-related activities and many only return to the room to unwind for a short time and sleep. More airflow is required when guests occupy a room; only low-volume airflow is needed when rooms are unoccupied.

Marriott’s committment to healthy indoor air quality and energy savings
In 2010 Marriott Hotels contacted American Aldes with indoor air quality concerns and a requirement to improve the energy efficiency of ventilation systems.

The goals were to provide constant balanced and regulated exhaust and makeup air in each space at the recommended rate at all times, and provide efficient demand ventilation when needed; ensure healthy indoor air quality for guests; control stack effect; and realize energy savings in the process.

Aldes recommendations
Among the recommendations was to install American Aldes Zone Register Terminals (ZRT) for exhaust in each guest bathroom and supply air in each vestibule or sleeping area. This would provide dynamic pressure-independent system control and demand control for both exhaust and supply air.

ZRTs are designed to control a prescribed amount of constant low-volume airflow and demand boost when needed. ZRTs contain pressure independant constant airflow regulators, CARs, that automatically adjust to changes in pressure, keeping airflow consistent regardless of the amount of pressure in the system. This compensates for the opening and closing of dampers, stack effect and other environment-related pressurization control issues. ZRTs are also designed to provide demand boost ventilation when needed; a closed damper allows precisely regulated low volume airflow. When the system is activated by an occupancy/humidity sensor, light switch or wireless transmitter (depending on the control system), the damper opens, allowing precisely regulated high-volume airflow.

American Aldes believed that installing ZRTs would eliminate under ventilation (ventilation rates being too low when rooms are occupied) and overventilation (ventilation rates being too high when rooms are unoccupied). Because ZRTs provided balanced ventilation, the risk of cross-contamination from room to room would be eliminated. This more efficient use of ventilation—with airflow rates that align with the times when rooms are occupied–would save on energy costs.

Installing and evaluating ZRTs
Over the course of one year, ZRTs were installed in guest room vestibules for supply air and in guest bathrooms for exhaust ventilation. ZRTs in guest vestibules were set to shut off when the room is unoccupied and automatically supply a regulated volume of 40 cfm when occupied. ZRTs in guest bathrooms were set to shut off airflow when the bathroom is unoccupied and automatically exhaust air at a rate of 35 cfm when occupied.

American Aldes and Independent Engineering Firms (for unbiased interpretation) assisted Marriott with calculating the energy impact of continuous versus demand controlled ventilation. American Aldes Engineering department developed the AVCE6 performance calculator built using TMY data over the past 20 years to give the most precise and effective results.

Marriott includes American Aldes ZRTs in Global Design Standards
Marriott quickly recognized the value of American Aldes ZRTs, which now included the optional wireless technology that was breaking ground worldwide. Marriott showed an average of $200 per room in energy savings annually, taking an estimated 1.4 years to recover the cost.

Energy savings was at the top of the list. However, the guest experience was overwhelming and complaints diminished drastically, so much so that Terry Smith, Vice President of Engineering Global at Marriott International added American Aldes ZRTs to the Global Design Standards for all new Marriott properties. The mechanical design standards now include ZRTs for the Guestroom Supply Ventilation (a ZRT in the vestibule ceiling to supply makeup air), and the Guestroom Bathroom (a ZRT in the shower and toilet compartment to provide exhaust ventilation). Since 2011, tens of thousands of Car-II’s & ZRTs have been installed in hundreds of Marriott properties worldwide and continue to be specified in all new buildings and in renovations.

Aldes-developed solutions continue to benefit Marriott and other Hotels
During the course of Marriott’s renovations, other property owners that manage both Marriott and other hotels requested American Aldes’ assistance in working with local and state energy companies. Aldes is now providing solutions to the Massachusetts area through Eversource, the state energy corporation. Eversource utilizes the Aldes-developed AVCE6 to calculate the rebates to be given based on projected savings utilizing the CAR-II line up.

American Aldes CARs to be installed in luxury condominium at 160 Leroy in NYC

American Aldes has again partnered with A.D.E. Systems Inc. of New York, to secure the sale of ventilation products, Constant Airflow Regulators (CARs), for a new luxury condominium building, 160 Leroy in New York City’s West Village. The prestigious new building, designed by Pritzker Architecture Prize winners Herzog & de Meuron, will house 57 one-of-a-kind residences starting at $2.4 million.

Each apartment home will have views of waterfront and/or the city from floor-to-ceiling windows. They’ll include and a host of luxury features such as custom solid mahogany entry doors, custom-designed bathrooms with material palettes of natural stone and hand-selected wood, 11 to 13 foot ceilings, custom-designed lighting. All residences are prewired for audio-video, dimming and motorized shade systems. The building is expected to open in 2017.

Aldes Constant Airflow Regulators will be a part of the ventilation system. These devices automatically regulate airflow in duct systems to constant levels. The passive control element responds to duct pressure and requires no electric or pneumatic sensors or controls. The CAR compensates for changes in duct pressure caused by thermal stack effect and provides a low-cost solution to balancing forced-air systems, eliminating the need for on-site balancing. CARs are frequently specified for many different applications, including multi-family projects such as 160 Leroy.

Other recent projects in which A.D.E and American Aldes have partnered include the Hilton Garden Inn on Park Avenue in Midtown New York, the RIU Plaza, 520 West 28th, the Visionaire Building, 50 West Street, 30 Park Place, 260 Park Avenue South, Greenwich Lane Complex, 313 West 37th Street, W57 Durst, 432 Park Avenue, The Enclave at Cathedral, One Riverside Park, 111 Murray and dozens of other properties in New York City and New Jersey.

Some of NYC’s tallest residential buildings use American Aldes Constant Airflow Regulators

There’s a new building currently on the rise in New York City’s Midtown at 220 Central Park. When complete later this year, it’ll soar 66 stories, house 118 luxury condominiums, and top out at an impressive 950 feet tall, making it one the tallest residential buildings in the United States. As most mechanical engineers and HVAC contractors know, tall buildings come with big a ventilation challenge known as stack effect. Residents at this high rise won’t have to worry though, American Aldes Constant Airflow Regulators are already part of the building’s ventilation system that eliminates stack effect and maintains healthy indoor air quality.

What is stack effect? Tall building ventilation systems can become severely out of balance due to outdoor pressure differences. The result is higher airflow at the top levels and stagnant air on lower floors. Stack effect can also cause cross contamination, meaning stale air is drawn from one floor and forced back into another. Balancing airflow to keep each floor at a constant, precise airflow can be extremely challenging, labor-intensive and expensive. Constant Airflow Regulators are self-balancing and correct stack effect by automatically adjusting to the changes in static pressure so that energy is not wasted and optimal indoor air quality is maintained. For a more comprehensive look at American Aldes’ solution to stack effect, see our application guide.

220 Central Park South, owned by Vorando Realty Trust and designed by architect Robert A.M. Stern, is expected to top out at 950 feet. By comparison, One57 (also in NYC) currently ranks 2nd place at 1,005 feet while 70 Pine Street (NYC) stands at 952 feet and ranks 3rd.

Other recent projects in New York City that include American Aldes Ventilation products are W57 Durst, 432 Park Avenue, The Enclave at Cathedral, One Riverside Park, 111 Murray, 160 Leroy, and dozens of other properties in New York City and New Jersey.

Later this year, American Aldes Constant Airflow Regulators will be installed at 53W53—also known as MoMA Tower—which will rise 82 stories and join the ranks of New York City’s tallest residential buildings.
