Mazzetti Mazzetti Thu, 14 Nov 2019 00:26:59 -0500 en-US hourly 1 Women @ Mazzetti – Fall Update Thu, 14 Nov 2019 00:25:20 +0000 It’s officially fall season and the color of the leaves are changing. Mazzetti has also gone through a few changes the past few months, leading our % of women to decrease.

As expected like the seasons, things change, and we keep moving on. On the bright side, there are some exciting activities Women@Mazzetti has been doing including attending the Society of Women Engineers national conference in Anaheim this month and starting an internal women leadership mentoring program.

We (Angelica Chow and Cassidy Thompson) are not just W@M co-chairs; we are also actively involved with the Society of Women Engineers, a non-profit organization supporting women in engineering that started nearly 70 years ago. Both of us were former officers involved with outreach and business development in the Cal Poly San Luis Obispo collegiate section. And now, we are both a part of the leadership team in the Golden Gate professional section.

With an expected attendance of over 14,000 people, the SWE annual conference (WE19) in Anaheim, proved to be inspiring, resourceful, and empowering. We were inspired by the stories of overcoming adversaries from keynote speakers and attended sessions discussing and teaching everything from time management skills to zero net energy buildings to recognizing bias.

As engineers working in the AEC (architecture, engineering, and construction) industry, the presentation on zero net energy (ZNE) buildings really got our minds thinking. California is on the fore front of energy efficiency with ambitious goals for zero net energy buildings. We can see the state moving towards these goals, especially with the most recent code cycle of Title 24, Part 6, which now includes healthcare facilities. This is important for our California offices (San Francisco, Irvine, and Sacramento) given the healthcare aspect of the projects we work on. One aspect of a ZNE building that the presentation focused on was embodied carbon. While energy standards help us focus on building performance and energy usage, we also need to pay attention to the carbon dioxide emitted during the manufacture, transport, and construction of building materials. The more we learn about energy efficiency and zero net energy, the more we realize the importance and our role in building better and sustainable buildings for the future. It’s exciting time to see how our industry will change as we must comply with new standards and change the way we design in order to achieve zero net energy and zero net carbon goals.

Technical talk aside, at WE19, we also learned the importance of recognizing our value as women engineers, the innovative and diverse ideas we can bring to the table, and to not downplay our achievements. We are both very happy to work for a company that realizes all of this. With a CEO, managers, and co-workers who support and advocate for us, we have found ourselves as stronger and more confident engineers. And until the day we reach our ambitious goal of being the most women-friendly engineering firm, Mazzetti and W@M will not stop advocating for women in engineering.

NEWS: Seasoned MEP Engineer Stacey Lin Joins Mazzetti Wed, 02 Oct 2019 17:39:00 +0000 Please join us in welcoming seasoned MEP Engineer Stacey Lin, PE, CxA, who joined Mazzetti as a Principal in San Francisco. He brings 25+ years of experience, specializing in sustainable design.

We sat down with Stacey to learn more about his background and outlook on the future…

How did you get into your specific line of work?

I became interested in math and science before high school, and I knew I wanted to eventually do something technical. When I started looking for a job after a master’s degree in Mechanical Engineering in 1990, the economy was down. I contacted many firms and a stand-out was an energy consulting company specializing in energy conservation. They were looking for engineers to analyze building energy consumptions using DOE2 (the most popular program for comprehensive energy analysis at the time); my background in fluid and thermal sciences made it easy for me to learn and use program. After three years, I joined a well-known Pacific Northwest MEP firm to broaden my background in mechanical engineering. I have continued my career in MEP design and energy efficiency consulting for 29 years which eventually led to me Mazzetti.

Tell us about a memorable project…

It was a high-rise mixed-use project. My firm provided mechanical design for a design-build contractor based on design concepts presented by another firm. When the construction was nearly completed with occupancy permit planned to be received in two weeks, we received really bad news – the building’s stairwells and elevator shafts could not be balanced to be within the pressure range specified in the new code. The change in the code allows the deletion of vestibules into the stairwells on each floor, but its implications were not fully understood by anyone. I was asked to come up with a fix in less than two weeks! Through sleepless nights, frantic analyses and full support from other team members, I arrived at a solution and gained 15 minutes of fame too!

What excites you most about your line of work?

Consulting engineers are in a unique position to contribute directly to tackling sustainable growth and climate change. I am excited about making my work relevant and impactful!

How did you discover Mazzetti?

I was working in Portland when a local firm merged with Mazzetti. I knew Mazzetti worked on mostly healthcare and complex projects, and I also learned throughout the years that the firm is willing to bring in new talents through mergers, which demonstrates the leadership’s willingness to embrace change.

What are you most excited about, working for Mazzetti?

I am excited about the opportunity to lead a team of engineers to provide quality engineering solutions. Firms that can attract and retain talents and equip them with advanced design tools will be in high demand by our clients.

Advice for the younger generation?

Consulting engineering is technical work, but it also forces young engineers to improve their people skills – communication, empathy and teamwork. These skills will benefit anyone, but especially make an engineer more effective and valuable.

Life outside of work??

Being a Principal, it’s hard to separate work from other parts of your life. To me, physical and mental health is the most important asset, so I try to exercise regularly and keep up with reading.
One quote I appreciate is: “Treat your family like friends and your friends like family.” I enjoy spending time with them, and my appreciation only grows.

What does the future of the A/E/C industry look like?

My own view is the A/E/C industry will go through transformations in the next decade. Firms will get bigger & there will be fewer of them in the landscape. Changes will be ongoing in order to meet demand for speedy deliveries and to keep pace with advancements in other industries.

What if we “reimagined” the ICU alongside clinicians? Thu, 29 Aug 2019 22:39:14 +0000 Have you heard, our Sextant Foundation is organizing another “Reimagining Workshop” focused on critical care spaces

On the final day of the Healthcare Facilities Symposium (in Boston), Thursday September 19, we’ll kick off the next two-day “Reimagining Workshop” focusing on critical care spaces, presented by the Facility Guidelines Institute (FGI) & theSociety of Critical Care Medicine (SCCM). We’re assembling leading designers and clinicians, including folks from Harvard, Kaiser, Brigham Woman’s, Mayo Clinic, and more. Participating architects and clinicians earn continuing education credits. REGISTER HERE.

So, WHY focus on critical care?

ICU patient story
This patient’s story is just one of the PEOPLE impacted by our ability to improve, to reimagine critical care spaces. This patient prioritized:
• Access to the outdoors
• A patient-accessible dimmer switch to control the lighting
• An electronic “board” for documenting her feelings and overall state-of-mind, while in the ICU, connected to her medical records, and accessible to her

Though this ICU did accommodate her desire for direct outdoor access, unfortunately not the case for the other priorities. How else can we reimagine this space to improve her experience (and that of others)?  Let’s do it together, in Boston!

Standard registration ends Sept. 6.

Lighting the Way: How John Muir Health Overcomes Lighting Design Challenges Thu, 15 Aug 2019 04:29:35 +0000 Background:

Over time, growing healthcare systems without design standards will naturally manifest noticeable inconsistencies, particularly when it comes to lighting. (Similar to any organization, increasing in size typically warrants a greater need for standardization and increased clarity.) Consider when you’ve experienced a healthcare lobby and while venturing to the patient room, felt the unmistakable discontinuity as your visual environment alters dramatically. John Muir Health (JMH), an expanding not-for-profit based east of San Francisco, started experiencing this inconsistency with their own lighting. In particular, as LED technology has significantly advanced over the years, facilities with the older generation LED lighting were literally glaringly different compared to newer facilities with upgraded LED technology.  When you’re in the business of wellness and healing, the physical (visual) environment must be a priority — JMH recognized this priority and sought assistance to standardize lighting design for existing and new facilities.

“We knew we needed a consistent look and feel as we continue to expand and renovate spaces, particularly given recent advances in lighting technology. We needed to be able to tell designers, for new projects, the type of luminaire and lighting design per specific performance criteria.”

  • Peter Spadia, JMH Senior Project Manager for Facilities Development.

“After a recent build-out, not incorporating higher tech controls for lighting, we knew we needed to take action toward resolving this systemically,” said Peter.

Earlier this year, an opportunity emerged from an Outpatient Center (OPC) project, yielding extra design capital – this was it!

Having a long-tenured relationship with Mazzetti for various MEP design and now lighting design needs, JMH contracted with Mazzetti. The mission was set. JMH needed:

  • Performance metrics and criteria for a variety of spaces including new construction, LED retrofits and “one for one” replacements.
  • Increased quality of visual environment for staff, patients, and family by building consistency in the lighting systems.
  • Streamlined maintenance and access to information regarding the lighting systems.

A significant piece of the maintenance objective involved JMH’s internal engineers. They needed a map/guidelines for relamping and other maintenance, as well as trusted manufacturer recommendations.

JMH established the following comprehensive goals:

  • Carefully integrate electric lighting and lighting control systems with daylight, architecture and interiors, to create an enjoyable and aesthetically pleasing visual experience.
  • Provide lighting and control systems that are specifically designed to align with human circadian cycles, promoting the health and well-being of patients, staff and family, while improving patient recovery.
  • Create lighting systems that are visually comfortable while supporting the wide range of visual needs, tasks, and special requirements within the facility.
  • Design lighting systems utilizing current technology that can respond to future changes in the healthcare industry by being flexible, adaptable, energy efficient, long-lived and easy-to-maintain.
  • Include the design team and owner, develop lighting design options that can be evaluated based on the owner’s requirements, lighting performance metrics, visual quality, aesthetics, maintenance, and cost.
  • Establish lighting budgets and performance criteria that can be tracked to ensure that goals are being met; enable the owner and design team to make (more) informed decisions on the lighting system.
  • Engage the owner, patients, and staff via mockups, sharing current issues on light and health and various design concepts for input on how to meet the needs and wants of the users.


Mazzetti jumped into action, working closely with JMH staff. First step was discovery — evaluating lighting conditions at existing JMH facilities. Mazzetti toured existing facilities to evaluate pre-existing lighting and received input from staff regarding their lighting needs.

The JMH facilities assessments involved:

  • Gathering and reviewing As-Builts if available, printing floor plans for each space to be evaluated.
  • Evaluating existing conditions that impact the visual environment, documenting each with notes and photographs.
  • Taking illuminance readings in each space, or typicals.
  • Noting reflectances and other lighting quality issues such as glare, contrast, and uniformity issues.
  • Noting lamps and luminaire types, including manufacturer data for reference on typical fixtures.
  • Meeting with maintenance/facilities to discuss current relamp/retrofit replacement approach.
  • Discussing lighting conditions with staff and building users.
  • Discussing lighting control use, manufacturers, likes/dislikes with JMH, noting areas needing improvement, including exterior.

What was discovered through these evaluations and conversations?

Maintenance staff would often replace lighting without knowledge of color temperature, CRI, lumen output, etc. In addition, clinical staff expressed concerns over not knowing how to control the lighting, much less the intended functionality for optimal operations.

Mazzetti spent two days with JMH staff reviewing and evaluating current lighting to produce a lighting audit report. This report included existing documentation, including a lamp list; calculating existing lighting power densities and current energy usage; calculating energy savings, ROI, and possible paybacks with various strategies. This was augmented with narrative, including goals for the future.


JMH is now equipped with lighting design standards and guidelines plus design strategies for each space, including bringing existing spaces to current standards:

  1. Relamp, Retrofit kits or One-for-One Replacement
  2. Renovations
  3. New Design

Mazzetti crafted NEW lighting design standards addressing the following criteria:

lighting design criteriaThe new standards and guidelines include brief space descriptions, lighting metrics for the quality and quantity of light, design recommendations, and luminaire and control recommendations to build the much-desired consistency in the lighting systems across the JMH campuses, including off-site facilities. The lighting design recommendations include a basis of design for luminaire and control selection, highlighting any coordination issues depending on the application. Regarding maintenance, JMH now has a trusted lighting replacement go-to matrix  for facilities staff to use on new LED lamps or retrofit kits. This addresses recommendations for ongoing maintenance ranging from simple lamp replacement, to luminaire replacement, to new design and construction projects.


JMH is gearing up for a significant retrofit design project, for which, Mazzetti is providing the MEP design.

“We’re looking forward to implementing these new standards and reaping the benefits,” said Spadia. I’m grateful to have worked with the Mazzetti team on this effort. I appreciate their knowledge and enthusiasm… they’re just fun to be around and very good at what they do! This work will ultimately benefit our patients, visitors, physicians and staff.”

This will be the first official project using the new standards. The anticipated benefits will include facilities with warmer, more visually pleasing lighting with better patient and staff control. Lighting will have more consistency, energy efficiency, and will (better) aid in patient and staff satisfaction.


Mazzetti referenced a variety of codes, guidelines, and industry standards while developing the lighting design standards/guidelines including:

  • Title 24 –
  • Illuminating Engineering Society of North America (IESNA) –
  • Office of Statewide Health Planning and Development (OSHPD) –
  • Facilities Guidelines Institute –
  • The American Society for Health Care Engineering of the American Hospital Association (ASHE) –

Mothers @ Mazzetti: Can you “have it all”? Tue, 06 Aug 2019 16:56:58 +0000 In 2017, my daughter Audrey was born. I started realizing what my life and career in Lighting Design needed to become… MORE FLEXIBLE.

If I was going to keep my career in Lighting, I needed to stay working full-time but couldn’t keep up with the travel demands at my previous job. I’m also a strong believer that you should love what you do for a living when you’re spending at a minimum most weeks 40+ hours doing it, not to mention the guilt of leaving your child behind in someone else’s care. I experienced a moment of clarity — my next job had to be worth it. This equated to an enjoyable job, yes, but also life, if not, industry changing. I needed a role, in which, I was empowered to impact the lighting design and architectural industry while specifically focusing in Healthcare, creating healing spaces… And, I wasn’t going to stop until I figured out a way to “have it all”. That’s the dream right?! I’ve never been one to settle.

When I connected with Mazzetti again in 2018, I was interviewed by three men, one specifically that would become my current boss. All three had families and were big proponents of a work/family life balance. I even interviewed via Skype in my kitchen while watching my daughter in the other room. If a company was interested in me, they’d have to be flexible, and in turn, I would promise to make it worthwhile for the company!

Once I started at Mazzetti, all that talk revealed to be the true reality. I was now part of a company with a boss who fully supported me. I was able to take off when my daughter was sick, make up time when needed, and I’ve never felt shunned or judged by any one of my coworkers. I traveled (still do) when needed, all my pumping kit of parts in tow, while Brennan (yes, my boss), has helped me preserve that balance, even if I had to be on the road. I’ve never been asked to do more than I could handle (or anything beyond my comfort level with respect to the “balance”).

Sidenote: I recommend this useful resource re breastfeeding/pumping/etc.

Fast forward to 2019, after only a short amount of time working for Mazzetti, I became pregnant again with my second child. My son was an emergency C-Section birth. It’s the scariest situation followed by the hardest time I’ve ever been through physically and emotionally recouping from it. The support I had leading up to my son’s delivery and after has been more than I could have imagined. Multiple people to share and vent to or get advice from with the flexible time I needed to recover yet still work and manage a home. What’s surprised me the most, is not that I was allowed flexible work conditions but that some of the people who have opened up to me the most about balance and what women go through have actually been men.

In 2018, a couple female Lighting Designers conducted a survey — Why Women Leave Lighting Design. Out of 452 women surveyed, only 37% of those were mothers who have STAYED in Design. Most left due to inflexible employers, including insufficient benefits. I’m happy to say, this isn’t the case for me.

Companies like Mazzetti, who hire people, female and MALES who believe in a work/life balance and offer flexibility to working mothers will continue to thrive. Since my short tenure at Mazzetti, improvements have been implemented to our company guidelines, including accommodation/renovation in every office for lactation rooms. We have our Women @ Mazzetti group, in which, I can openly speak and gain support from; but it’s larger than that. For me, I wouldn’t go through any of the stresses of this work/life balance through these child-rearing years with any other company. This is my Thank You to Mazzetti and the men and women in it (you know who you are) for your support and patience through these post-partum years.

The best part? I’m currently designing the lighting for Randall Children’s Hospital Family Birth Center with our Portland office. Fair to say, I’m a true asset to the client given my recent, 1st-hand experience to offer!

Below, is our monthly “Women @ Mazzetti” tracking, keeping us informed in terms of our specific female diversity in the company…


Women @ Mazzetti – Increasing Temperatures & Numbers Mon, 15 Jul 2019 22:17:26 +0000 Halfway through the year of 2019, which means, the summer heat is rising! Likewise, as of the month of July, our % of women at Mazzetti and our % of women in technical positions continue to rise.

Women @ Mazzetti - July 2019

A quick update re Women@Mazzetti activity… We are forming a women-in-leadership mentoring program. The goal – for employees at Mazzetti to have access to and mentorship from women in Mazzetti’s leadership. Over the next few months, we will be interviewing the mentors and sharing their knowledge gems both internally and externally (spreading the wealth!)

Recently, we came across an article from NPR, “Battle For the Thermostat,” discussing research analyzing how temperature affects the productivity and cognitive abilities of men and women differently. The study reports a 10-15% increase in math and verbal performance for women and a 3% decrease for men when the temperature changes from the 60’s to mid-70’s (Fahrenheit). The study implies an interesting question then – how do we design temperature for gender-mixed spaces?

Our Mazzetti-ites brought up a few good points regarding gender versus temperature. One thing to note is how clothing factors into the results; women on average probably wear less clothing or thinner clothing than men, hence making them more susceptible to cold temperatures than men. Alternatively, if the office temperature were higher, then men would likely be uncomfortable due to their increased clothing coverage compared to women. Another point to keep in mind is that heat loss relates to surface area and mass. Women on average have a smaller build than men; therefore, women generally dissipate heat more quickly than men.

At a minimum, we can conclude that temperature can yield a significant effect on the people, for which, we design spaces. Awareness is step #1. Curious to hear your thoughts… Check out the references below and share your thoughts on how we can achieve the “right” temperature for all!

M+WasteCare Calculator WEBINAR – July 30th Tue, 02 Jul 2019 18:56:03 +0000 Healthcare waste managers, like you, cannot easily determine the environmental impact of their waste stream disposal decisions, resulting in subpar sustainability outcomes. Mazzetti is increasing visibility and access to waste stream environmental impacts with a FREE online calculator, M+WasteCare, to better understand your waste footprint and make more informed decisions with your waste streams.

Join us Tuesday, July 30 at 11:00am PDT for a free webinar on the M+WasteCare Calculator.

John Leigh, Director of Sustainability at Virginia Mason Medical Center in Seattle, Washington, will share his story of challenges in managing waste and measuring impacts – and how this tool has helped. He’ll give a brief live demo and answer questions about waste disposal methods, emissions, reporting, and more. John has worked in waste management for nearly 30 years, and in healthcare for the past 15.

“There are a number of important features that I like about this waste impact calculator:

  • For the first time, we can calculate the emissions and pollutants resulting from the specific treatment and disposal methods we use for hospitals’ specialized and varied waste streams.
  • It factors in transportation emissions based on miles traveled as well as fuel type used for each travel leg.
  • We can input different scenarios for comparing one course of action against another.
  • It’s open source and now crowdsourced – the assumptions and conversion factors are completely transparent and open for others to improve upon.
  • It’s powerful, easy to use and understand, and it’s free!”

Packard Children’s – ASHRAE Technology Award – 1st Place (Health Care Facilities) Fri, 14 Jun 2019 18:15:20 +0000 Updated August 19, 2020

ASHRAE Golden Gate Chapter AND ASHRAE REGION X Recognize Lucile Packard Children’s Hospital Stanford with 1st Place Technology Chapter Award (Health Care Facilities)


The ASHRAE Technology Awards committee recognizes outstanding achievements by members who have successfully applied innovative building design in the areas of occupant comfort, indoor air quality and energy conservation. Their designs incorporate ASHRAE standards for effective energy management and IAQ. Performance is proven through one year’s actual, verifiable operating data. Awards Ceremony: Golden Gate June Chapter Meeting – June 20


When you walk into Packard Children’s, you know you’ve entered a special place. The building (which opened its doors to patients December 2017) was, from the start, intended to be one of the most sustainable hospitals in the world. The entire design and construction team—Perkins+Will, Mazzetti, HGA, and DPR Construction—was instrumental in finding ways to back up that claim.

“We have so much pride for this project… Driving success for this project stemmed from its leaders and donors that wanted to create a ‘different’ environment–integrate art, beauty, and light into the healing process. This was the original vision, and this is what we proudly delivered.”

Brian Hans, Associate Principal and Senior Mechanical Engineer, Mazzetti (a member of the Packard Children’s project team)

The catalyst for this project — to accommodate growing capacity needs. In a hospital where the sickest of sick children are cared for, the overarching goal of the project was to create an environment that aides in healing by providing patients and visitors warm, comfortable, light-filled, and uplifting spaces, creating a “home away from home.”

The new 521,000sf (net sf) building (713,000gsf), sits atop a 192,000sf garage, more than doubling the size of the existing pediatric and obstetric hospital campus. The new building adds 149 patient beds for a total of 361 patient beds on the Palo Alto campus. It includes four floors consisting of two wings of ICU and ACU patient care beds, 12 Operating / Interventional Radiology rooms, a full imaging area that includes MRI, CT and PET/CT, a grand light-filled lobby, public areas, and 3.5 acres of green space with gardens and artwork for patients, family, and staff.


As the MEP & Sustainability Engineer on the project, we worked early and closely with our design partners to achieve a precedent-setting sustainability profile, including LEED Platinum certification — the 2nd children’s hospital ever, the 4th hospital in the country, and 5th in the world to earn this certification. The site has an EUI of 180 kBtu/ft^2 and a source EUI of 394 kBtu/ft^2.

“The Packard Children’s Board was really concerned with not just building a great hospital to treat children but to be a minimal impact on the community and the environment… One of the most if not the most sustainable hospitals in the country.”

Jesse Avery, Associate Principal and Senior Electrical Engineer, Mazzetti (a member of the Packard Children’s project team)

Working alongside our design partners, we achieved the intersection of human health and environmental health (not sacrificing one to achieve the other). Some of the design elements incorporated towards this include:

Displacement Ventilation

  • Patient rooms – low sidewall displacement ventilation (DV) with radiant heating reduces fan energy, reduces cooling energy, mitigates re-heat energy, improves infection control, improves thermal comfort, and reduces ambient noise from ventilation which has been proven to reduce environmental fatigue
  • ICUs – Overhead DV system to meet code requirements while enabling energy savings and promoting occupant comfort
  • Entrance Lobby – Incorporated DV into the structural columns to seamlessly integrate the mechanical systems and provide efficient air distribution to reduce energy consumption and improve occupant comfort

Optimized exterior façade
Developed a fixed external shading strategy which was optimized with the mechanical systems to almost eliminate direct solar gain for the entire year and facilitate the implementation of the displacement ventilation system for the patient rooms

Waste Anesthetic gas recovery

  • Designed an innovative anesthetic gas recovery system to collect and ultimately reprocess the waste gas to mitigate greenhouse gas emissions and recycle the released gasses for future use
  • This is one of the first installations of this technology in the US

Water reclamation
On-site water cisterns collect rainwater, Reverse Osmosis purge water and condensate for irrigation needs. All the irrigation needs for the site are provided by the system and potable water is virtually eliminated for this purpose.


  • The use of daylighting has been optimized to maximize natural light, access to views, and mitigate energy consumption in many areas of the hospital. The patient rooms and corridors have been optimized to mitigate direct solar gain while leveraging daylighting and access to views.
  • Other areas such as the PACU have used skylights to bring in natural light to minimize lighting energy use, aid in staff mental health, and facilitate connection to the outdoors for staff and patients.

Green spaces
Planted gardens have been incorporated into the dining courtyard, main entry play area, staff garden, catwalks, and overlooks on each floor

Data center ventilation
The data center is strategically placed on the roof to maximize outside air use to mitigate mechanical cooling by leveraging air-side economizers. Higher operating temperatures and a wider range of permissible RH conditions in the data center allow the use of chilled water return being used for cooling the data center to maximize chilled water delta T and facilitate maximum hours of economizer use.

Reclaimed wood
Much of the accent construction materials for the project used reclaimed wood which came either from the site or nearby demolition projects at Moffett Field.

Airport Sustainability: Something Worth Noticing on Your Next Trip Fri, 24 May 2019 04:02:25 +0000 As I touched down in unseasonably warm summertime Seattle, stirring from cross-country flight induced semi-consciousness, my thoughts solidified… not on sustainability and global warming but instead on something different and intriguing – airplane cooling.  Little did I know, the two were related.

We (Mazzetti) have a long-standing reputation for designing high-performing, highly sustainable healthcare facilities across the country. However, many people may not be fully aware of our similar work in Aviation. (The hub of this work located in the Emerald City.)

I was traveling to Seattle to present an AIA session  on “Designing for Sustainable Behavior” and to meet with our Sustainability core team.  As I disembarked the plane, instead of being in “preparation mode” as I usually would be, all I could think about was the plane getting colder after we landed.  Why did the plane get colder? Why would the pilot land and then blast the air-conditioning? And, in a city that’s considered fairly “green”, wouldn’t running the jet engines at the gate, be counter-efficient?! I’d never experienced anything like it before.

Then as I walked to the downtown train noticed the signs explaining “pre-conditioned air” or PC Air.  Seattle Tacoma International Airport (SeaTac) is the largest airport to implement this at-the-gate ventilation system. When a plane lands, conditioned air is blown into the plane so the jet can get fresh air without running its engines. The results — improved air quality, reduced noise, increased energy efficiency, and lower energy costs for airlines (which can equate to lower rates for passengers!).

“Our region expects this from us,” said SeaTac Project Manager Ken Warren. “Our customers and our airlines expect us to do everything we can to protect air quality.”

In fact, the annual GHG emission reduction is equivalent to taking 8,000 cars off the road. (Yes, you read it correctly — taking 8,000 cars off the road!) The Pre-Conditioned Air Project won first place in ASHRAE’s 2015 International Tech Awards.

I made it to our office in North Seattle and had the opportunity to talk with Leslie Jonsson, a Mechanical PE well-versed in SeaTac projects. Leslie is passionate about sustainability and always has been a “voice” for sustainability well before it was “cool”. (BTW, Leslie’s career is truly inspirational – check out more here.)

Leslie reminded me that Mazzetti has worked with SeaTac Airport for 30+ years.  Naturally, I asked about sustainability at the airport. I instantly saw the excited twinkle in Leslie’s eyes. Most recently, Mazzetti was a mechanical sustainability consultant on the significant North Satellite Modernization Project, the expansion and renovation of a 45yr-old facility. (Groundbreaking began in February 2017 and the first five new gates were opened earlier this year, with more opening later this year. More details here.)

The expansion is targeting LEED silver. Mazzetti is managing the LEED credits for indoor air quality (mechanical) and for water efficiency. Interesting initiatives includes a rainwater harvesting system, capturing 2/3 of roof rain water, serving 42% of toilets and urinals, and a green wall, for which, Mazzetti designed the plumbing.

The rainwater harvesting system is only a part of the story as the facility is also committed to water conservation through the use of low flow fixtures. As participating members of building water systems risk management, our designs balance the risk and sustainability factors (which often conflict).

As I waved goodbye to my Seattle colleagues, I looked forward to returning to SeaTac with a new appreciation.  As a Benefit Corporation we’re accountable to drive environmental benefit… As I stepped on the plane, I felt thankful to better understand how that extends to aviation.

Given the upcoming holiday weekend, you may find yourself venturing through a nearby airport… Perhaps you might be more cognizant of the visible and audible sustainable elements… Perhaps you’ll have a greater appreciation of the “behind-the-scenes” work to make it all happen. ‘

Do you have an airport sustainability story? We’d love to hear it — share here.
