Guest Blogger: Paul Doppel

Paul Doppel is our senior director of industry and government relations. He works closely with AHRI, the DOE and other government organizations, utility companies as well as green building groups to enhance HVAC technology education and applications.

June 4_Guest Blogger - Paul Doppel - IGR Update ImageDear Readers,

We’ve seen an unprecedented amount of regulatory action over the past few years. The demand for actions that support a sustainable future grows stronger every day. HVACR regulations are constantly undergoing revisions as a result. It’s paramount to stay informed in order to keep up with these demands, and part of my job is to help.

For starters, see a rundown on what’s happening on Capitol Hill below.

  • The House Subcommittee on Energy and Power has raised concerns with the EPA’s rulemaking, which targets certain refrigerants as greenhouse gases and prohibits their use in many applications, including product-development costs and the risk in using unproven, alternative compounds.
  • ASHRAE 188P is close to becoming a published standard. It requires a commercial building to have a water management program with Legionella control measures if it has:
    • A device that releases droplets into the air (think cooling towers, evaporative condensers, spas, fountains, misters and humidifiers).
    • Multiple housing units with a centralized hot water system.
    • More than 10 stories.
    • A majority of the occupants over 65 years of age.
    • Patients who stay more than 24 hours.
    • Patients at a greater risk of contracting Legionnaire’s disease.
  • President Obama signed the Energy Efficiency Improvement Act of 2016, which is projected to yield roughly $4.6 billion in annual energy savings by 2030. The Act includes four budget-neutral provisions:
    • Commercial building owners and tenants are to align interests to reduce energy consumption.
    • Certain electric resistance thermal storage water heaters are exempted from pending DOE regulation.
    • Federal agencies must develop an implementation strategy for the maintenance, purchase and use of energy-saving technologies.
    • Federally leased buildings without ENERGY STAR labels must disclose their energy usage data.
  • Two bills have been referred to the Senate for voting:
    • Bill HR 636 will revise Section 179 to make the $500,000 allowance for expensing depreciable business property permanent. It will also add HVAC equipment to the definition of qualified property.
    • Bill HR 185 will require a thorough analysis of any new proposed regulations, including a cost-benefit analysis and increased public participation.

ASHRAE and IAQA Join Forces

ASHRAE-logoOctober 9_ASHRAE and IAQA merge_Image2

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Indoor Air Quality Association, Inc. (IAQA) announced on July 14 that they are combining forces. IAQA, the nation’s largest indoor air quality trade association, is now part of the prominent industry organization. The groups will work together to improve indoor air quality in the building environment.

The collaboration is expected to result in stronger programming and services. Indoor air quality technical guidance and educational programs for industry members should benefit, as well. The most significant result, as suggested by ASHRAE President Tom Phoenix, is “improved indoor air quality for the world around us.”

Study Shows Advanced Controls = Energy Savings

July 16_Advanced Controls and Energy Savings Field Study ImageBack in October, we told you about ASHRAE’s co-sponsored Advanced Rooftop Unit (RTU) Campaign, which encouraged commercial building owners and managers to replace packaged RTUs with energy-efficient systems or retrofit them with advanced controls. A year-long field study conducted by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) proved commercial buildings could cut their electricity use by an average of 57 percent with advanced energy efficiency controls.

The PNNL team retrofitted a total of 66 RTUs at eight commercial buildings in Washington state, Ohio, California and Pennsylvania with advanced controls. One-minute interval data was collected from the units over a 12-month period. They compared the results to the buildings’ energy consumption pre-retrofit (without advanced controls) and found that:

  • Advanced RTUs resulted in an average of $1,489 energy savings per year.

  • Advanced RTUs reduced energy consumption by 22 to 90 percent, depending on the size of the unit.

  • Energy savings increased with size of unit.

  • Large units (e.g., greater than 15 tons) and units with long runtime (e.g., 24/7 operations) had the shortest payback periods.

  • Upfront costs of installing or retrofitting systems with advanced controls could be recovered in an average of three years.

Based on the results, PNNL concludes that approximately 285 trillion Btus of energy could be saved if just 50 percent of the packaged RTUs in the U.S. were retrofitted with advanced controls. That’s equivalent to removing more than 70 coal-powered power plants or more than 10 nuclear power plants.

Click here for the complete field study results. For a summary of the findings, read the “Improving Operating Efficiency of Packaged Air Conditioners & Heat Pumps” article in the March 2014 issue of ASHRAE Journal.

The Path to Acceptance: History of VRF Zoning Regulations in the U.S.

Variable Refrigerant Flow (VRF) zoning technology is the fastest growing HVAC technology in the industry today. Mitsubishi Electric introduced the technology to the U.S. more than 10 years ago and has spent the last decade building the category nationwide.

VRF zoning now fills an enormous gap in the country’s cooling and heating needs, but in the early 2000s there was little awareness of this technology. We realized then that the success of VRF zoning technology in the U.S. required a paradigm shift in how the industry and end users thought about cooling and heating solutions.

To initiate this shift we focused on two approaches: to build training and market education at the grass-roots level and to simultaneously spearhead government regulations.

We knew that certification was critical to industry acceptance and, by extension, to end users. We became active members of the HVAC and energy communities, chairing ASHRAE committees, participating in DOE discussions, meeting with members of Congress and becoming active in AHRI. We are proud to have pioneered the introduction of this technology to the U.S. and the subsequent regulatory acceptance.

We have achieved many milestones already and today have an entire department dedicated to advocating for the unique performance capabilities of VRF zoning in the U.S. To see how far we’ve come, here are some of the regulatory milestones that have paved the way to official industry recognition of VRF zoning technology:

ASHRAE, NAHB and ICC Combine Forces to Develop New Green Building Standard

April 9_3 logos
The National Association of Home Builders (NAHB) announced last month that ASHRAE will join forces with the association and the International Code Council (ICC) to develop the 2015 ICC/ASHRAE 700 National Green Building Standard (NGBS). This marks the third adaptation of the standard and the first time that ASHRAE has partnered on its development. As long-time advocates for green building, we’re thrilled to see ASHRAE team up with the NAHB and the ICC to both advance and promote the values of sustainability.

A joint NAHB and ICC committee first developed the NGBS in 2007. The committee included home builders, code officials, product manufacturers, government representatives and building science and energy-efficiency specialists. The American National Standards Institute (ANSI) approved the standard in 2009 as the first green standard for residential construction, development and remodeling. The NGBS was updated in 2012 and since then has been used to certify more than 32,000 residential constructions. In fact, the NGBS now serves as the leading standard in the industry for sustainable home building, a growing trend in the U.S. market and a sector that is expected to represent as much as one third of the building market by 2016.

For more information on the upcoming NGBS, click here to read the full press release from NAHB.

Mitsubishi Electric Talks Energy Savings for Historic Retrofits in Home Energy Magazine


Our own Pam Androff recently penned an article for Home Energy magazine, the premier publication for residential building pros focused on energy reducing practices. Appearing in the January/February 2014 edition, Pam’s article profiles the Mitsubishi Electric installation at Baltimore’s Union Mill, an 1886 historic stone mill, which underwent an adaptive reuse from an industrial plant to a mixed-use facility housing retail space and apartments.

Certified under Baltimore City Green Building Standards, the retrofit of the 10,000-square-foot facility featured energy-saving features such as our R2-Series system, a centralized controller with a Tenant Billing function as well as high performance makeup air, energy recovery ventilation, double-pane low-e windows and the thermal mass provided by the building’s 2-foot thick original stone walls. Driven by models that compared standard packaged central units to our VRF zoning system, the project engineers were able to project an overall energy savings of 40,000 kWh annually.

According to Pam, “The project’s baseline modeling methodology was consistent with LEED® and ASHRAE 90.1 protocols, and the proposed energy efficiencies resulted in a whopping $164,258 cash rebate from Baltimore Gas & Electric’s Smart Energy Savers Program.”

To read more of Pam’s article, check it out on Home Energy’s website here. You can find a case study as well as testimonials from the Union Mill project team here.

2014 AHR Expo: Day 1 Rundown


“Innovation doesn’t take a snow day,” AHR Expo tweeted yesterday. Judging by the thousands of people we’ve already seen in our booth and on the exhibition floor – and the reports of day 1 being the busiest day of AHR Expo ever – we couldn’t agree more.

We kicked off the industry’s main event yesterday morning with a press conference in our booth, where we introduced our new, state-of-the-art Hyper-Heating INVERTER (H2i®) M-Series and R2-Series systems. The unveiling of these products came with two groundbreaking announcements: the H2i M-Series features the highest SEER rating in the industry today and, with the newly added R2-Series, we now have the industry’s most complete family of Hyper-Heating, cold climate products. We continued the excitement with our annual dinner event – this year at Cipriani – where 400 attendees came out to help celebrate our big reveal and ring in this year’s show.

Day 2 is already proving to be just as good as the first! Our H2i R2-Series is already making a splash on the scene, having been recognized at today’s award ceremony for its Honorable Mention designation in this year’s Innovation Awards program. To top it off, we’ve also received RSES Journal’s 2013 Readers’ Choice Award, proving that hard work and dedication does pay off!

We’re only half way through this year’s AHR Expo, which means there’s plenty more to come. Visit our booth, #1679, to hear more about the exciting news we have to share and make sure to come back to the blog tomorrow for a recap of today’s show. As we said before, with an event this big, you don’t want to miss a beat.
