ASHRAE ‘s newly adopted 90.1-2019 addresses the main entryway of commercial buildings 3,000 ft2 & larger. Commercial building owners, architects, HVAC designers and contractors can now specify air curtains to satisfy code and reduce energy loss in commercial buildings provided that the air curtain has been tested and certified in accordance to ANSI/AMCA Standard 220, which requires a minimum air velocity of 400 fpm (2 m/s) at the floor, regardless of the mounting height.

Below is a new case study available on the Mars website
At a newly constructed Harley-Davidson 10,000 sq ft showroom in Chicago, our Mars Standard 2 air curtains were installed across a large expansive opening of garage style roll up doors that opened direct to the sidewalk and adjacent to the street. The air curtains blocked dust, untreated air, debris, flying insects, and smelly vehicle emissions from entering the room.
Studies reveal a 6%-9% upside effect on work performance based on improved air quality and temperature. (Wyon 2004)

The Mars Air Systems online course, Energy Savings with Air Curtains, is now on AEC Daily’s Online Learning Center! This course offers 1.25 PDH Hours for design professionals, and highlights some of the features mars has to offer!
Mars air curtains reduce building energy costs, keep environments sanitary through the elimination of flying pests and debris and ensure consistent building temperatures using an invisible unobstructing flow of air. Put Mars to work at all your openings including entry/exit doors, pass-thru windows, dock doors, receiving doors and create internal climatic separation and realize comfortable results as well as financial results.

Energy Savings with Air Curtains
Meet the new generation of BARD Wall Mount Units! Set to meet DOE requirements of 11EER for SPVU equipment, BARD took the challenge with several new features in their redesign that meet the changing HVAC field with the performance and reliability we have known BARD for historically! Keeping with the same wall fit of the previous units, this new unit will fit perfectly on a retrofit. The new features include a new C cabinet eliminating the need for right and left access selections and allowing for great service access to the compressor, filter, condenser coal and electric heat coils! The new units also feature a new Balanced Climate feature to assist in efficiencies and enhanced humidity control, natural fiber insulation, brushless DC motor, new dehumidification system and low leak design! Follow the link below for more details on the new generation of units and the added design and contact your local John J Morgan representative for selections or more information on this innovative new Wall Mount Unit!

DEPT OF ENERGY GETTING SERIOUS ABOUT REDUCING ENERGY USAGE — TO THE TUNE OF $33.5 MILLION
The news is out … the U.S. Department of Energy wants to invest $35 million of grant money to help reduce our energy usage — in both commercial and residential buildings. At Mars, one of our core missions has been to reduce energy usage and help commercial operators realize the secondary benefits:
— reduced burdens on commercial HVAC systems extend the lifecycle of the equipment
— lessening the work of the HVAC systems reduces maintenance and operating costs – they work better, harder & longer
— a longer life for your HVAC equipment reduces commercial waste and landfill materials
Specifics from the announcement include:
- The DOE seeks solutions that will allow energy efficiencies after building retrofits, with goals that include a 75% reduction in major loads from HVAC systems. The agency is also interested in construction technologies that can help new buildings achieve a 50% increase in energy efficiency through techniques such as offsite manufacturing, robotics, digitization, automation and improved modeling.

With a growing demand for smaller and more flexible units, we are now including the Total Recovery Low Profile (TRLPe) to our Total Recovery series. The TRLPe is a cETLus and HVI certified compact model designed to fit tight spaces. Featuring an energy recovery core with a MERV 8 filter, the TRLPe is the perfect ERV for multi-family homes and residences with low ceilings.

Great news from Reznor!
Just released is the R7DA DOAS/high OA unit. It is designed for both replacement and new instillation.
- Extremely competitive Price Point
- Patented HG system for increased efficiencies
- Fits on existing Carrier Curbs
- Electrical requirements similar for direct replacements
- 6 & 7.5 ton (up to 20 by the end of the year)
- Rust-less condensate pan
- NG, LP or Electric Heat
- Vertical or Horizontal Airflow (field modified)
- ECM supply Fan
- Variable Speed Compressor (10-100%)
- 1″ Foam insulation
- Control System built-in (Constant CFM, Building Pressure, ect.)
- DDC or local control options
From my experience this is a great unit to fill the tenant buildouts, restaurant, nail salon, and other projects meeting the need for increase ventilation and first cost concerns. Please see the attached cut sheets and let us know if you have any questions.
