Is your facility reaping the monetary benefits of RCx?


Over the last 12 months, one of our valued clients has saved a total of $983,470 from RetroCommissioning (RCx) services. Their cost after rebates was $584,380, with a payback of 0.6 years! Thanks to the assistance of Mazzetti’s experts, our client has reaped the benefits RCx services can provide. See more details here.

Are you reaping these benefits?

As industry experts, our responsibility is to see opportunities for our clients and advise accordingly, especially opportunities for savings and energy reduction. According to the 2017 Johnson Controls Energy Efficiency Indicator (EEI) Survey , HVAC equipment remains the most popular improvement. These mechanical systems often operate inefficiently for various reasons–lack of funding for repairs or replacement, insufficient knowledge of proper operation, inadequate staff, and poor documentation, to mention a few. Temporary repairs are common, and in the age of sophisticated systems, small issues can often manifest into large problems in healthcare facilities. Through the RCx process, building owners are made aware of specific areas requiring attention and restore their building’s performance with the help of a detective.

What exactly is RCx?

RCx is a systematic process for identifying and implementing operational and maintenance improvements in a building to ensure continued healthy performance over time. RCx goes beyond maintenance measures to identify deficiencies that aren’t always so obvious. That experienced detective, also known as a Commissioning Authority (CA), provides strategies that can lower utility bills and provide other benefits–reduced maintenance costs and improved occupant comfort and indoor air quality.

Low-hanging fruit

Consider your own facility. How confident are you in the effectiveness of your existing Building Automation Systems (BAS)? Do you think you’re “ringing out” (hence the banner image) the full value of your BAS to increase efficiencies, particularly re energy efficiencies?  The data suggests more value is available for most facilities with little to no capital costs.

You can discover more about Mazzetti’s Cx and RCx solutions (including our EXPERTS) here. 

Did you know, that if your facility runs at a 5% profit margin, every dollar in energy cost you save is equal to grossing $20 of additional revenue?

Our client recently distributed their annual savings report, which documents each project’s overall cost and savings. We thought this graphic  might help illustrate, literally, reaping the benefits of RCX, “ringing out'” every ounce of value.

Building Capacity & HOPE to Combat Cholera in Haiti


Public Hospital in Miragroane

On January 12, 2017, the New England Journal of Medicine, noting the scale of the cholera problem in Haiti – “already a disaster before the hurricane hit” – described a short, medium, and long-term program for “ambitious action on cholera control and elimination in Haiti.” This program was developed by the Haitian Ministry of Health in consultation with the US National Institutes of Health.

The program started with humanitarian relief for the population affected by the hurricane, coupled with “a simultaneous need to ensure that cholera treatment centers and oral rehydration posts are functional. After the hurricane, many of these facilities will have to be rebuilt.”

Shortly after the hurricane, a team of Mazzetti and Sextant Foundation volunteers accompanied Project HOPE’s medical volunteers to assess some of the facility needs in the state of Nippes, an area heavily affected by the hurricane. As a result of that work, Project HOPE was able to secure financial support for the needed construction.


Mazzetti and Sextant volunteers with Project HOPE team

Volunteers from Mazzetti and the Sextant Foundation worked with Project HOPE leadership to design a new Cholera Treatment Center for the public hospital in Miragoane. That project drew upon best practices for other CTC’s in the country, and optimized cost, speed of construction, versatility (so it could also be used for other purposes once cholera needs abated), usability, and lessons learned from the other superb designs elsewhere in the country. Mazzetti’s design volunteers included world-class architects from HKS (who also helped Mazzetti with the Philippines’ Typhoon response) and MASS Design Group (who designed the brilliant CTC for Gheskio Foundation in Port au Prince), as well Fall Creek Engineering, who helped to design the waste water treatment facilities for the Gheskio CTC. The building will feature cost-effective operational features such as on-site chlorine generation; it will be completely powered with solar energy with extensive battery back-up, as  power in the area is notoriously unreliable.

Mazzetti and Sextant volunteers managed the construction and performed the electrical and plumbing work, working with and training local contractors in Miragoane.

As the successful construction project comes to completion, Project HOPE will move toward important long-term planning for capacity building to help the country to, as suggested by NEJM, control and eliminate cholera and support sustainable health system strengthening in Haiti.

Message from Mazzetti CEO Walt Vernon:

We started the Sextant Foundation after volunteering to help Project Hope following the 2010 Earthquake in Haiti. Seeing the good that Project Hope does in the world was life-changing for me, and we modeled the Sextant Foundation more or less after Project Hope – bringing volunteers from US healthcare to provide desperately needed infrastructure to support their medical missions. I am so happy that we are continuing to find ways to work together like this, empowering the people of Haiti to manage the health issues they face. Thanks to all of our donors and volunteers.

Haiti’s Urgent Need for HOPE Combating Cholera


What an opportunity in the “Season of Giving”

We said we’d be back. And now we have that opportunity to follow through. Following the reconnaissance work via the Sextant Foundation and Mazzetti employees Walt Vernon, Tamara McDonald, and Johnny Chung, Project HOPE was able to secure funding to construct the new Cholera Treatment facility requested by the Minister of Health from the state of Nippes, in Haiti. Read more from our reconnaissance trip in early November.


Haiti is currently bracing for an expected onslaught of Cholera, following the recent devastation of Hurricane Matthew. Approximately 2.1 million people were impacted by the storm, leaving 1.4 million (12% of Haiti’s population) in need of assistance in some capacity. As of October 14, the death toll was at 546 with 128 people missing and 439 injured. The Haitian government estimates nearly $1.89 billion in damages, including primary healthcare infrastructure in the state of Nippes; the country has no resources to rebuild. Project HOPE and Mazzetti/Sextant, at the request of the State Minister of Health, have planned, designed, and are beginning construction on a new cholera treatment facility at Hospital St. Therese, in Miragoane, the capital city of Nippes.


On January 12, 2010, an earthquake of 7.0 magnitude hit Haiti. It killed 1⁄4 million people, injured over 300,000 and left 1.6 million people homeless. Far from the epicenter, CRUDEM Foundation’s Hôpital Sacré Coeur survived the earthquake and thousands were flown in by helicopter. When most NGOs, including Project Hope, sent only medical workers, Project HOPE also sent engineers. The goal was to assess the remaining health facilities to best deploy medical professionals with infrastructure that supported these medical missions. Thus was born the Mazzetti/Sextant Foundation and our long-running commitment to improving health facilities in places in the most need. View the video here.

Months after this earthquake, the country faced a new challenge. Cholera. Though not endemic to Haiti, prior to the earthquake, Cholera broke out, killing thousands. More on the suspected cause of the outbreak here.


Since returning from our most recent recon trip, We have sent Jeff Rodriguez, friend of Mazzetti’s, Sextant Foundation activist, and former Hospital Facility engineer, back to Nippes (in Haiti) where we will meet with Project HOPE members and local Haitians to start work. Haitians urgently need more cholera treatment accessibility. Through Project HOPE’s coordination with the Haitian government and specifically the Ministry of Health, we have planned, designed, and will construct a cholera treatment center. The center will be located at the St. Therese Hospital in Miragoane, the capital of the state of Nippes. The new facility will include 20 beds and a bioreactor, for hospital waste water treatment, appropriate to the local maintenance abilities. It will be powered by solar panels to eliminate the need for expensive diesel fuel. It will be designed to treat cholera victims, but the Ministry intends to use it beyond any potential cholera outbreak to treat various diarrheal diseases into the future.

Mazzetti/Sextant is sending two more of our people early in the new year to help complete this project. Our volunteers will mostly oversee the work of Haitians who we will pay to perform the bulk of the work, thus providing some level of economic benefit to the people there, as well.

Mazzetti/Sextant are funding 100% of the costs of our volunteers, and we can use your help. If you can, please donate here:

Bloom Energy Fuel Cells


Bloom Energy

Seven Southern California Sites

4.6 Mega Watts




Full MEP Design Services 

Generating 100% renewable energy on-site for seven healthcare facilities

Technical Information

The Bloom Box Beta version is a 200 kW Solid Oxide Fuel Cell (SOFC) module.  These fuel cells generate electricity via chemical reaction with natural gas or bio gas.  The inside of modules are comprised of stacks.  These stacks are multiple groupings of cathode, electrode, and anode plates.  Reformed fuel passes through the anode side while oxygen (air) passes though the cathode side.  As the chemical reaction occurs, electricity (electrons) are created.

CH4 + 2O2  CO2 + 2H20 + e- + Heat

This chemical reaction releases heat which is recycled back into the process.

The fuel cell system operates on a 24/7 basis, constantly creating electricity.  We call this a baseload offsetting system.  For most facilities, the electrical consumption during the middle of the day is generally higher than at night or the early hours in the morning.  The fuel cells were sized for the minimum base load of a facility.

Bloom Energy’s fuel cells create 100% renewable energy on site for each of the seven healthcare locations.

Environmental Attributes

Today, community demands for electricity is significantly increasing; utility companies need to procure more electricity to keep up with these demands. By providing these fuel cells, we are providing a community benefit by avoiding another plant to come online.  The seven facilities are offsetting approximately 37% up to 81% of their respective utility consumption. Our collective projects with Bloom Energy are anticipated to offset 15,008,683 lbs of CO2.

2020 ENR Best Project – Health Care, CA

Sustainable Consulting and MEP 

Defining innovation since 1959: New Stanford Medical Center will be adaptable to future expansion and technology


Staying Innovative

What worked for the patients in 1959 (when the Stanford Hospital was first built), differs for the patients now and in the future. The new hospital, located in the hotbed of Silicon Valley, is scheduled to be completed in 2018 and open to patients in 2019. The framework and development of the new hospital will be adaptable to future expansion of the Medical Center while technologically adapting with evolving interdisciplinary operations in healthcare.

Read more

The hospital is designed as a horizontally organized, modular medical center, and the systems within are equally impressive. From a mechanical perspective, the air handlers feature a unique dual air tunnel design, thus, eliminating downtime while providing redundancy. A PLC (Programmable Logic Controller)-based controlled fan wall system was designed to manage optimum energy efficiency aligned with the project’s LEED Silver goals. Mazzetti is enlisting the latest in filter technologies using UVGI with photocatalytic oxidation filters. The unique, isolated base structure of the air handlers provided a natural thermal labyrinth in the crawl space to pre-cool air that is supplied to basement mechanical, electrical, and main technology rooms. The smoke evacuation system for the atria also doubles as a pathway for natural passive ventilation, leveraging the open spaces.

Promoting Sustainability

Stanford, known for innovative user-focused facilities, is pursuing LEED accreditation. Mazzetti, specializing in sustainable design, is employing energy and water efficiency, day-lighting, solar technologies, and greenhouse gas emissions reduction systems to achieve a LEED Silver (or higher) goal. These include a specialized curtainwall system, specifically designed for the hospital, incorporating high performance glazing with integral solar-controlled shading devices and a pressure controlled internal cavity. The plumbing system designs are capable of 96 hours of back-up fuel and potable water storage, fire water storage, as well as waste water storage with automated switchover. The lighting system designed incorporates approximately 90% LED fixtures with fully programmable lighting controls.

A condensation collection system stores clean captured water for intelligent irrigation on the green roof. The plumbing designs will take advantage of the sunny climate to power low-flow fixtures, using ambient lighting to charge sensor-controlled fixtures and flush valves. The domestic hot water system will collect waste heat indirectly from the central sterile equipment to pre-heat domestic hot water.
The new hospital will also implement sustainable practices, using specific medical equipment, including the anesthesiology administrator. A separate waste anesthetic recovery vacuum pump system will be installed with an anesthetic gas recovery system to sequester and ultimately recycle anesthesia and reducing energy consumption.

The Patient Experience

The new hospital will thoughtfully reinterpret the original design from 1959, welcoming patients and visitors with a light-infused atrium of daylight and landscape to the lower levels. Introducing lush green spaces like the open air courtyards, rooftop green space and glass-wall views to the foothills in the distance, creating a calming atmosphere. Accessible roof gardens on the third and fourth floors will be accessible by patients to enjoy the fresh air. The amenity-rich Garden Level on the third floor roof includes a a cafeteria, restaurant, conference center, staff lockers, and a lounge area, all of which overlook a green area.

While the proposed ventilation system was designed to lower energy costs for Stanford, the new system also reduces the risk of infection from airborne contaminants. Increasing the hospital by 824,000 square feet will allow for more single-patient rooms, realizing reduced infection rates, increased privacy for patients, and more space for patient families and visitors.

Stanford is technologically setting new standards in healthcare–state-of-the-art imaging equipment (48,000sf devoted entirely to imaging), flexible surgical and interventional OR rooms, and a new Level 1 Emergency Department (three times the size of the former department).

• Level 1 Trauma Center

• 32 flexible surgical and interventional operating rooms, an imaging department, and Heli-Stop

• Features roof gardens, green roofs, courtyards to bring outdoors inside

Data Center Projects Increase Energy Efficiency


Premier Global Communications Provider


Completion Date:  

Energy Incentives Secured:  

Suite of Energy Services & MEP

Improving energy efficiency, financed with incentives, while increasing operational efficiency


Start with Efficiency

Since 2011, Mazzetti has served as an energy efficiency consultant to this client, a premier global communications provider. This partnership started when we initially helped with selecting a controls vendor to implement the current front-end controls that had been deployed throughout their data centers across the country. These controls provide remote access for cooling system automated control as well as energy efficiency data to enable continuous commissioning of these systems.

With this background, we have continued to provide consulting for additional retrofit projects to improve cooling air delivery efficiencies by way of air containment measures and retrofitting Computer Room Air Conditioning (CRAC) units with Electronically Commutated Motor (ECM) plug fans. For these projects and the control system retrofit projects, Mazzetti secured significant utility energy efficiency incentives to offset implementation costs.

Financial Mapping

As part of financing-identified projects, we have helped the client secure over $3.2 million in utility energy efficiency incentives/rebates. Mazzetti developed custom energy models, approved by utility incentive programs, as part of securing incentives for the client.  This process has equipped Mazzetti with unique knowledge of the existing cooling systems for all of the client’s major facilities around the country.

Perhaps most significantly, Mazzetti has leveraged its intimate knowledge of the client’s cooling system operations to provide life cycle cost analysis studies of major cooling plant retrofits. The results have provided the client with the information needed to choose optimal paths for facility improvements and have identified pinch points in systems to help guide the facility on future technology deployment. These studies have led to several projects for which Mazzetti provided design services and helped support partial financing of these projects through additional utility energy efficiency incentives. By working on these projects nationwide, Mazzetti has unique knowledge of over 50 utility incentive programs across North America.

A Roadmap to the Future

Our goal is to continue working closely with the client to develop flexible options that will provide a cost efficient way to manage growth while maintaining MEP system reliability and redundancies. As we provide these services, we actively stay attuned to changes in utility incentive programs for leveraging the highest possible energy efficiency incentives/rebates available for any given project.
