Clean Air Solutions for Indoor Air Quality

 

 

 

 

 

 

  (Reduce Outside Air By 75% And Improve Air Quality)

An increasing number of commercial buildings are employing energy conservation products and practices to cut energy costs. Heating, ventilation, and air-conditioning (HVAC) represents the largest energy use in commercial buildings. History has proven that buildings with insufficient ventilation compromise the health of building occupants. Enersave is the solution.

What İs EnerSAVE ?

 

Enersave uses ASHRAE Standard 62’s Indoor Air Quality Procedure to cut energy costs while improving IAQ Enersave reduces outside air requiremments and HVAC loads. How? By recirculating air that would previously have been exhausted and using Purafil’ s chemical filtration systems to keep air clean. Enersave provides substantial operational saving and minimizes upfront capital costs.

 
 

Enersave Uses Ases Ashrae 62: IAQ Procedure

 

ASHRAE, the American Society Of Heating, Refrigerating, and AİR-Conditioning Engineered, was one of the first Professional organizations to develop standards relating to IAQ fort he well being of human occupants.

ASHRAE 62 – 1981 Established the IAQ Procedure, which allowed buildings to reduce outside air requirements by recirculating air sufficiently cleaned with an air-cleaning system. The procedure was şntended to help buildings conserve energy, while not ignoring the importance of clean indoor air.
 

Prior to 1981, the Standard specified the minimum and recmmended outside airflow rates necessary to provide acceptable IAQ. Known as the Ventilation Rate Procedure (Diagram 1), this procedure is stil applied today. Buildings using this method rely on ventilation air to dilute pllutant levels.

Unlike the Ventilation Rate Procedure, the IAQ Procedure (Diagram 2) does not prescribe ventilation rates; instead, it allows designers to use ‘’any amount of outdoor air’’ if IAQ is acceptable to human accupants.

 
 
 
 
 
 
 
 

 

Though the IAQ Procedure provides a direct solution for controlling pollutants and energy saving, engineers often default to the Ventilation Rate Procedure because of the complexities associated with IAQ.

In 2002, ASHRAE approved an interpretation that outlines how to implement the IAQ Procedure in seven simplified steps and includes the following:

  • IAQ modeling
  • Documentation
  • Chemical filtration
  • Ongoing system verificetion
 

EnerSAVE: The Purafil Solution To Rising Energy Prices

Enersave allows an engineer or building manager to reduce outdoor air improve IAQ. Purafil provides superior air filtration systems along with documentation and ongoing verification reports necessary to comply with ASHRAE 62’s IAQ Procedure.

 

Use EnerSAVE In:

Existing Bulidings

Implement the IAQ Procedure with no additional capital expenses! Slide out your existing particulate fitler and slide in the Purafilter for particulate and chemical filtration. For higher levels of gaseous contamination, insert a 2’’ r 4’’PuraGRIDA fitler in conjunction with your existing particulate fitler. Cut caots even more by reducing the total demand on heating and cooling equipment. You’ll save on operational costs, and the the reduced demand will extend the life of your conditioning equipment.

Rework Applicatins

For buildings undergoing occupancy changes or chiller redesign due to refrigerant changes, capital expenditures are often required to handle the increased outside air demand to meet ASHRAE 62’s Ventilation Rate requirements. With Enersave Purafil will replace the existing oarticulate filters with Purafilters or insert PuraGRIDs, evaluate the building and provide the calculations and support necessary to comply with ASHRAE 62’s IAQ Procedure

New Construction

With Enersave , you can rreduce overall equipment sizing for tremendous cost savings on capital purchases. Prafil offers a broad range of modular systems to meet your specific airflows, contaminant levels, and space requirements. Purafil will work with your construction engineers to assure the ptimum balance of energy savings and proper ventilation required to handle the increased outside air demand to meet ASHRAE 62’s Ventilation Rate requirements. With Enersave, Purafil will replace the existing particulate filters with Purafilters or insert PuraGRIDs, evaluate the building, and provide the calculations and support necessary to comply with ASHRAE 62’s IAQ Procedure 

 

Purafil Filtration

In a typical indoor environment there are as many as 100 different chemical contaminants.Only Purafil’s Unique Air Filtration Technlogy İs capable of eliminating these contaminants and reducind their concentretion levels to those prescibed by  ASHRAE 62’s IAQ Procedure.

Purafil’s air filtration technology is an integral part of Enersave. All of Purafil’s systems – from pleated chemical filters to modular units – combine the power of our patented media formulations with custom engineered solutions!

 

EnerSave Case Study:Century Center

Owned and managed by Highwoods Properties, 1800 Century is an 18-story commercial Office building in Atlanta. Georgia that faced possible upgrades in excess of $ 300.000 when a high-occupancy tenant moved into the entire facility. Constructed in the late 1970s, 1800 Century Center could not provide adeqiate outside air fort he added number of people. To comply with current codes, including minimum outside air requirements for increased occupancy, Highwoods potentially had to maket he following extensive renovetions:

  • Adding a new make-up air unit (MUA) to the roof
  •  Renovating the building’s structure to handle the weight of the MUA
  • Installing new duct from the basement to the roof to accommodate more outside air

Highwoods sought a feasible, cost-effective way to avoid purchasing new aquipment and restructuring the facility. Engineers from McKenney’s Mechanical Contractors and Engineers handle the tenant upgrade and brought in Purafil and local representative Kathy Nix (AirEnergy, Inc.) to help.

 

Purafil Provides The Solution

Purafil representatives implemeted Enersave, an energy-savings program that reduces the need for outside air and stil meets ASHRAE 62-2004’s indoor air quality (IAQ) Requirements. Using ASHRAE 62’s IAQ Procedure, Purafil engineers deelopel en IAQ model to verify that Enersave would  work in Century from an environmental standpoind. They recalculated outside air requirements and accommodated building conditionss that existed before the tenant change.

As part of Enersave, Purafil installed two-inch Purafilters as pre-filters on every floor’s air handling unit. Eath Purafilter had a MERV-8 particulate fitler and contained Purafil CPS Bilend’’ media a 50/50 volume blend of Premium grade acti vated carbon (Purakol media) and sodium permanganate-impregnated alumina (Purafil Chemisorbant media) to remove a broad spectrum f contaminants.

Successful Results

 Highwoods Properties was completely satisfied with Enersave, which allomed them to reduce the amount of outside air brought into the building, control gaseous contaminants, and recirculate clean air. By using Purafil’s energy-savings program, Highwoods saved ver $300.000 in capital equipment purchases, and they have continued to renew their contract fort he past ten years!
