Its The Environment (...Stupid!)

Posted April 09, 2014 9:03 AM by larhere

That's the take away I had after reading a current article in the HVAC NEWS titled "Compressor Manufacturers Leaping Government, Refrigerant Hurdles". Matt Bishop of the NEWS spoke with representatives from nearly every compressor manufacturer serving the global HVAC/R industry.

My take-away is the over simplified answer to the question "What are the major issues shaping your business?" A short but complex answer, "The Environment" is driving compressor manufacturers, in response to HVAC manufacturers, in response to customers and in response to an increasingly complicated (and constantly evolving) set of requirements.

It's the Environment because the main issues are:

  1. Energy Efficiency (full load) to reduce power plant emissions of CO2. Customer requirements and expectation continue to increase. Standards are continuously being revised to mandate higher efficiencies.
  2. Part Load Efficiencies are receiving increased attention. Part load measures such as IPLV are seeing expanded use on newer products. New and improved technologies are being introduced to improve part load efficiency. Multiple compressor configurations are seeing increasing use.
  3. Development of new low and medium GWP refrigerants to reduce global warming impact from emissions of refrigerants from equipment during operation and service. Blending of different refrigerants continues to grow. Custom refrigerants are becoming common.
  4. Custom compressors are becoming the norm. Such "application optimized" compressors utilize unique design features that enhance part and full load efficiencies for the unique operating conditions of each market.
  5. Europe continues efforts to eliminate HFCs from the marketplace. Flammable (and) Natural refrigerants continue to see increasing acceptance.

The New Norm is Mass Customization Driven by the Environment (with continuing price pressure)

HVAC Industry Shows Strength!

Posted March 26, 2014 12:00 PM by larhere

In December we commented (HVACR Manufacturers Show Optimism for 2014) on a survey of one thousand HVACR manufacturers showing a high level of optimism. 79% of the respondents said their prospects for business were either "excellent" (19%) or "good" (60%) for the coming year. That optimism appears to be coming true as industry activity and results are coming in.

AHRI just released Shipment Data for January 2014 U.S. Residential Heating and Cooling Equipment showing such strength.

  • U.S. shipments of air conditioners increased 19.8% over 2012
  • U.S. shipments of air-source heat pumps increased 27.8% over 2012
  • Biggest increase ocurred in 3-1/2 to 4-1/2 ton sizes (+32%)

Activity and results at GEA Consulting are also at record levels through the first two months of 2014 with activity from International projects leading the way.

Indications are 2014 will indeed be a good 2014.

Beware the Energy Shift-Energy Efficiency IS Important!

Posted March 19, 2014 8:00 AM by larhere

It was less than a year ago that GEA's Duane Lom discussed in this blog a perplexing question in the HVAC and Buildings Industries at the time, "Why is Energy Efficiency Such a Hard Sell?" In evaluating the alternatives to reduce electrical consumption, wind came in at $48 to $95 per megawatt-hour and coal fired plants at $62 to $141 per megawatt-hour, but neither could compete with the use of energy efficiency (using existing state of the art technologies) which cost from zero to $50 per megawatt-hour. Why? Buyer apathy.

What a difference a year makes. A joint national survey by NEMA and NAM of 1,000 likely voters clearly illustrates increasing support for energy efficiency. Nine in ten voters support using energy efficient products and believe it's important to include energy efficiency as part of our country's energy solutions. The support for energy efficiency cuts across demographic and political lines.

Consider the results:

  • 94% support using energy efficient products. Seven in ten (70%) "strongly" support it.
  • 90% believe it's important to include energy efficiency as part of our country's energy solutions...and (gasp!) there is consensus among Republicans (86%), Democrats (99%) and Independents (88%).
  • 67% are more likely to vote for a candidate for congress who supports energy efficiency policies.
  • two-thirds or more of voters, regardless of party affiliation, are more likely to support investing taxpayers' dollars in energy efficiency

Are you ready for the shift to energy efficient buildings and HVAC products?

Common Mistakes with the Key Account Plans- (Video Summary)

Posted March 12, 2014 8:00 AM by larhere

One of GEA's representatives is a member of KAM, an organization focused on Key Account Management.

A recent KAM seminar looked at Key Account planning and began by considering what goes wrong most often. The logic is that if we can identify the common errors in advance then we are more likely to avoid them.

A short video presentation on this subject can be seen on the secure server in Vimeo at

The seven most common errors can be summarized as:

  1. The 'plan' is not a plan but simply a review of recent history
  2. The 'plan' is just an exercise in form filling
  3. There are no defined or poorly defined objectives
  4. The plan has not been agreed internally
  5. It is not clear who is responsible
  6. The plan is not agreed with the customer
  7. The activity is not properly defined -who - what - by when

Many tools, in the form of Excel spreadsheets or software programs, are available to facilitate the development of a proper Key Account Plan. It's better to invest more time in proper account planning than spending time resolving negative issues with customers, defending competitive attacks and constantly defending the price of your products.

Those who fail to plan and plan properly as described above are doomed to mundane performance or even failure. By investing time and resources in proper account planning you can achieve the following:

  • Maximize the effectiveness of your sales effort (sales hours/$ sold)
  • Grow profits
  • Increase customer satisfaction
  • Earn a greater share of the customer's business
  • Construct competitive barriers
  • Better able to measure and manage the performance of your sales staff

Further, you will find that your sales staff will achieve greater career satisfaction, earn more and stay longer with your company.

Customers like dealing with people and companies they trust. They trust companies who understand their business and put their needs as a high priority in the products and services delivered. A properly, co-developed account plan is the key to identifying and delivering on those needs and to earning trust.

10 Predictions for US High Performance Building in 2014

Posted March 05, 2014 8:00 AM by larhere

High performance builder Hammer & Hand (offices in Seattle and Portland) unveils its ten predictions for the High Performance Building Industry which you will find below. Read the full report at the Hammer & Hand Website.

1. Focus will move beyond Net Zero Energy to Net Positive Energy buildings.

2. Market mechanisms that reward energy conservation and renewable energy production will flourish.

3. Building energy codes will move away from prescriptive rules toward performance-based measures.

4. CO2 heat pumps will help transform heating and cooling performance.

5. US-made high performance windows will continue to make high performance building easier here.

6. Builders and designers of high performance homes will design ventilation systems with a focus on quality of ventilation rather than just quantity.

7. The US-led move to make Passive House more climate-specific will improve performance at both micro and macro levels.

8. Passive House competition will result in better software tools for high performance building practitioners.

9. Europe's push to eliminate thermal bridges in buildings will make high performance building more mainstream in the US, too.

10. China's interest in high performance building will propel US market.
