Case Studies

Location :
Ascent Media

A video production and engineering facility in Northvale, New Jersey

CHALLENGE :

This facility is a 32,000 square foot office building with existing large central roof-top units. This building was built in 1976 and has poor ventilation and IAQ issues with CO2 levels at over 1,080 ppm.

SOLUTION :

A roof mounted BPE-2000 Heat Recovery Unit was retrofitted to provide over 1,000 cfm of pre-conditioned fresh air that reduced the CO2 levels by over 64% bringing the levels well within the acceptable range and solved the IAQ issues in the area served by the retrofitted rooftop unit.


Location :
Manufacturing facility and office suite in Northern New Jersey.

CHALLENGE :

2000 Square foot office suite with central heating and air-conditioning had serious IAQ (Indoor Air Quality) issues. Manufacturing and welding facilities directly below offices area generated large amounts of carbon monoxide and combustion products. Heated CO and combustion products infiltrated office and carbon monoxide levels above 100 ppm were recorded and the office was evacuated.

SOLUTION :

Lack of Fresh make-up air was solved with direct vent BPE-XE-200 unit and two 19 watt fans (total power consumption 38 watts), providing fresh air and non-detectable CO levels. Saving $45,000 for new HVAC system. Additionally, air-conditioning and heating costs were reduced by one third.

Total cost under $5,000 for equipment and installation, while providing over 85% energy recovery with a payback of under 4 years or an IRRA of over 25%


Location :
Newark Liberty International Airport

International Airlines Back Office in Newark, New Jersey

CHALLENGE :

The back office areas were isolated from outdoor air intakes by new construction and steel reinforced concrete structural members. Conventional ventilation techniques with partial energy recovery and hot/cold water coils and ductwork were priced at over $100,000.00 and would have involved demolition and construction for installation.

SOLUTION :

A BPE-200 X-Type heat exchanger with a heavy duty 8” inline fan and a 200 foot long 8” flex line was used for fresh air supply. The BPE-200 X-Type heat exchanger was efficient enough to condition the outdoor air to within 5°F of room temperature without additional heating and cooling coils and greatly simplified the fresh air ventilation system. The entire system was installed for under $4,500.00.

The BPE-200 X-Type heat exchanger, fresh air ventilation system, saved over $95,000.00 compared to a traditional ventilation system that was priced at over $100,000.00, and provided additional energy savings.
