4 Technologies Driving Energy Efficiency Jobs


When you think of energy jobs, you may first picture someone fixing a wind turbine or installing a solar panel. These jobs are certainly on the rise. But as businesses and home owners increasingly seek cost savings on their utility bills, a large portion of energy jobs today — almost a third, in fact — are focused on efficiency.

More than 133,000 energy efficiency jobs were added in 2016, bringing the total number of Americans working in the sector to 2.2 million people. More than half of those jobs (1.4 million) are in the construction industry alone. Whether it’s construction, manufacturing, or wholesale trade, much of this job growth has been driven by four technology areas.

Efficient Appliances

More than a quarter of the energy efficiency workforce (552,000 workers) is related to efficient appliances, including high-efficiency heating and cooling equipment. That’s a 58% increase from 2015. U.S. Department of Energy (DOE) support continues to push the envelope on innovation across a range of common appliances – from high-performance refrigerators to more efficient air conditioners – with the ultimate goal of keeping more money in consumers’ pockets.


Another 25% of the energy efficiency workforce is employed in the traditional HVAC industry. While these 520,000 workers spend a majority of their time working with conventional heating and cooling services, part of their work is also dedicated to high-efficiency technologies.

Advanced Building Materials

Innovation has driven significant progress in reducing the energy consumption of buildings and homes, including technology advancements like next-generation windows and building envelope technologies. Better insulation and more efficient windows reduce the energy needed to heat and cool homes and commercial buildings. This saves money on utility bills and keeps occupants more comfortable.

These advancements also mean more job opportunities. Last year, 446,000 workers were employed in roles related to advanced building materials. DOE-backed research continues to develop new materials and methods to improve insulation and windows, including innovative sprayable insulation and new smart window coatings.


Another 327,000 workers are employed in the energy-efficient lighting industry.

DOE-backed research in solid-state lighting has yielded more than 260 patents and a significant industry footprint, with literally millions of products currently on the market based, at least in part, on these technical advancements. These products are estimated to have contributed to more than $2.8 billion in savings for consumers and businesses – an impressive return on an investment of about $350 million.

NEW Lab Exhaust Direct Drive Options


Greenheck’’s Vektor® line of laboratory exhaust systems now offers a direct drive arrangement 4 option available on Vektor-MH (High Plume), Vektor-MD (High Plume with Dilution) and Vektor-MS (Variable Geometry Nozzle) models.

The design combines a lightweight, aluminum mixed flow wheel with an industrial grade motor to provide low vibration and efficient operation. Maintenance is reduced as the motor does not require lubrication for up to one year, and, if necessary, the motor can be safely serviced through a bifurcated opening without disassembling the fan.


Life-Saving Innovation


More than just keeping people comfortable, HVAC technology can improve human life expectancy. Medical applications have helped to advance developments in surgery, decrease infant mortality, fight malaria, and stop bacteria from spreading.




The STULZ Mini-Space EC is a precision cooling system for small IT spaces, providing up to 12 kW (41 MBH) of cooling while only occupying a 2 ft. x 2 ft. (0.6 m x 0.6 m) footprint. It is ideal for small IT and telco closets, high-rise buildings, laboratories, and other constrained spaces.

STULZ is proud to have the broadest offering of chilled water (CW) and direct expansion (DX) precision cooling capacities in the industry. The Mini-Space EC is the smallest floor mounted computer room air conditioner (CRAC) in our product line. Our standard catalog floor mounted solutions go up to 750 kW (2,600 MBH) and beyond for custom indoor air handlers and other user driven designs.

The new Mini-Space EC is available with CW or DX cooling in both up-flow (top discharge) and down-flow (top return) configurations with options for bottom discharge (under floor), front discharge (direct room supply), and ducted rear return (with external filter box).

The Electronically Commutated (EC) backward curved plenum fan is the key to this product’s efficiency. Because it shares many of the same design aspects of the other STULZ floor standing products, we are able to provide a fully scalable air volume with EC Fans that are designed to operate at reduced speed. The result is significant energy savings and lower maintenance costs compared to belt driven forward curved fans. The small footprint and reliability make this product an ideal solution for IT users, engineers, and contractors looking to provide a space friendly and dependable cooling solution that eliminates hot spots.

The STULZ Mini-Space EC joins the STULZ CeilAiR® overhead units, STULZ CyberRow rack cooling units, CyberPack packaged rooftop units, and the STULZ Micro Data Center as a solution for small data center applications. The Mini-Space EC is fully compliant with DOE regulations and meets the requirements of ASHRAE 90.1-2013 for data center cooling units.

It’s an unfortunate reality that even in 2017, residential (comfort) cooling equipment is too often misapplied in small IT spaces. This is bad for both the equipment owners and the environment. Comfort cooling equipment is not designed to run 24/7 or to maintain the tight tolerances required for IT cooling, which results in unscheduled down time and unplanned maintenance costs. In contrast, STULZ mission critical equipment is designed to accept the high sensible heat loads produced by IT equipment and is more efficient with higher return temperatures. When you consider the total cost of ownership, the STULZ Mini-Space EC is the best solution for providing mission critical cooling in applications where minimal floor space is available.

The STULZ Mini-Space EC is available for order in North America from STULZ USA and its sales partners.

A Brief History of Precision Air Conditioning


STULZ and the road from computer room cooling to modern Data Center air conditioning: The history of precision air conditioning technology begins in the early 1970s with the air conditioning of countless computer rooms that are springing up. With the transition to the modern Data Center, the exceptionally diverse landscape of precision air conditioning solutions that we know and trust today gradually came into being – a process in which STULZ repeatedly took a pioneering role. The most important milestone was the CyberAir 1, which was the world’s first precision air conditioning system to be fitted with EC fans as standard.

In The Beginning: Precision Air Conditioning For Computer Rooms

When we introduced our first air conditioning system onto the market in 1965, precision air conditioning technology as we know it today was as yet inconceivable. The first STULZ system was also a comfort air conditioning system, which cooled rooms while also providing (unwanted) dehumidification. However, this system was not designed to air condition IT rooms. And it must be said that basically, there was as yet no market for solutions of this kind in the mid-1960s. This only happened when IBM launched its System/370 mainframe computer in 1970. Despite its high purchase price of $ 4.6 million, it evolved to become the most successful mainframe of its day, and revolutionized the use of IT. For the first time, computer centers were created on a large scale, although they were not yet known as Data Centers. One exception was the Deutsche Rechenzentrum in Darmstadt, founded in 1961 and which, even then, employed the German word for “Data Center” in its title…


The Effects of Screens on Louvre Performance


The effects of bird or insect screens on louver airflow performance is a commonly asked question. AMCA standard 500-L Airflow Performance does not consider the effects of appurtenances such as a birdscreen or an insect screen. As such, any published performance data does not take into account the effect of bird or insect screens, however, it is obvious that screens would increase airflow resistance.

To aid the HVAC system design engineer, Greenheck recently conducted pressure drop testing on two of our most popular louver models with various types of bird or insect screens in place. The sample test included a horizontal and vertical blade louver. As one might suspect, the results differ from louver type to louver type. The chart below depicts the average increase in airflow resistance for four commonly used screen types.

Application Example

Let’s assume a louver has 0.10 in. wg pressure drop at a specific volume or free area velocity. If it were an intake application, the estimated overall static pressure drop including a flattened expanded aluminum birdscreen would be 0.112 in. wg (0.10 x 1.12). For exhaust, it would be 0.105 in. wg (0.10 x 1.05).

In an upcoming eCAPS update Greenheck intends to incorporate a “screen effect” impact on calculated pressure drop so that design professionals selecting louver products can consider the additional average airflow resistance increase caused by a bird or an insect screen.

Flattened Expanded Aluminum Birdscreen (Intake) 12%
Flattened Expanded Aluminum Birdscreen (Exhaust) 5%
1/2 in. Mesh Birdscreen (Intake) 12%
1/2 in. Mesh Birdscreen (Exhaust) 7%
1/4 in. Mesh Birdscreen (Intake) 17%
1/4 in. Mesh Birdscreen (Exhaust) 21%
Insect Screen (Intake) 17%
1/2 in. Mesh Birdscreen (Exhaust) 17%
