HILO (HawaiiNewsNow) – Hawaii Island will commemorate the arrival of the first 15 Filipinos to Hawaii back in 1906.

A free Sakada Day Celebration in Hilo will take place on Dec. 20, from 9 a.m. to 1 p.m. to honor the contributions of the Filipino plantation workers who sparked a wave of migration.

“Filipinos are actually a large group here in Hawaii, lot of times things like this are actually tend to be a little neglected,” said Iris Viacrusis, co-chair of the Sakada Day Celebration.

This year’s event will feature a lei presentation at 9 a.m. at the statue at Keaau Community Center, followed by lunch, entertainment and a presentation to three descendants of sakadas: Sandra Claveria, Lorraine Rodero Inouye and Angel Pilago.

Two exhibits will also be displayed for guests to learn more about the sakadas — one will feature stories of the sakadas’ legacy and the other will showcase cultural items and clothing from Viacrusis’ collection.

Dec. 20 was proclaimed Sakada Day under Gov. David Ige in 2015.

Event organizers are preparing for next year’s 120th anniversary of the sakadas in Hawaii.

Meantime, on Oahu, a free Sakada Day Celebration is taking place today, Dec. 13, at Hawaii Plantation Village in Waipahu from 10 a.m. to 2 p.m.

The Philippine Celebrations Coordinating Committee of Hawaii, the University of Hawaii at Manoa Center for Philippine Studies and Filipino Curriculum Project organize the annual gathering, which honors the resilience, contributions, and cultural legacy of sakadas, migrant plantation workers whose hard work, courage, and spirit continue to shape the Filipino American experience today.

High school students will take part in stage performances, visual presentations, education booths and a fashion show.

The Hawaii Foodbank Kauai received two major grants of $25,000 each on Thursday: one from Kauai HMS Host and The Journey for Good Foundation by Alvota, and one from DraftKings and FanDuel.

A team from the Kauai HMS Host and The Journey for Good Foundation by Alvota visited the Puhi facility to present a check for $25,000 in support of the work being done by the Hawaii Foodbank Kauai crew.

“The opportunity to partner with The Journey for Good Foundation by Alvota was truly a gift given to us by our local HMS Host team,” Hawaii Foodbank Kauai Assistant Director Tisha Remigio said in an email. “When this amazing group came to volunteer last month, they got to see the true, on-the-ground operations of our food bank and what it really means to keep our families fed here on Kauai.”

“We learned that the funds for The Journey for Good Foundation come from such a simple, grassroots idea — those change bins at the airport checkout stands where customers can drop their loose change,” Remigio continued. “It’s incredible how that money, which seems so small, creates such a massive impact, such as the grant award. Our local HMS Host is such a wonderful group of people, and we are so fortunate for their ongoing support, not only with this monetary grant, but with the essential grocery rescue work we do with them on a weekly basis. We truly hope this inspires others to adopt a small and simple, yet everlasting, impact idea like this to help those in need on Kauai.”

The Hawaii Foodbank Kauai also announced, in a Thursday press release, the receipt of a $25,000 donation from DraftKings and FanDuel to directly support the purchase of an additional food delivery vehicle for the Hawaii Foodbank Kauai’s mobile food pantry program.

“DraftKings is committed to strengthening communities,” said Sabrina Macias, Senior Vice President of Global Communications and CSR at DraftKings. “We’re proud to support Hawaii Foodbank Kauai in expanding access to fresh, reliable food resources, and helping families across the island receive the nourishment they need.”

The DraftKings and FanDuel grant will also sponsor the Hawaii Foodbank Kauai’s upcoming Nourish Gala that will be held on Dec. 19 at the Royal Sonesta Kauai Resort, starting at 5 p.m.

Proceeds from the gala fundraiser will help nourish families in need across the island. Tickets and sponsorship opportunities are available by visiting the website at www.kauai.hawaiifoodbank.org, or by calling 808-482-2088.

“FanDuel is honored to support Hawaii Foodbank Kauai as part of our commitment to uplifting communities,” said Keita Young, vice president of community impact at FanDuel. “Food banks are essential pillars of local resilience, and we are proud to contribute to ensuring families across Kauai have consistent access to the food and resources they need.”

The new vehicle will expand the Hawaii Foodbank Kauai’s ability to deliver food, including fresh produce and shelf-stable goods across the island.

“We are deeply grateful for this meaningful gift from DraftKings and FanDuel,” said Hawaii Foodbank Kauai Director Wes Perreira. “With many households on Kauai facing rising food costs, partnerships like this with DraftKings and FanDuel help ensure that none of our friends, neighbors or ohana go hungry.”

University of Hawaii at Manoa and Lawrence Berkeley National Laboratory Teamed up To Analyze Feasibility of Geothermal Cooling Technologies

By Justin Daugherty, NLR

In areas with geologically recent volcanic activity and ample underground water flow, like the Hawaiian Islands, geothermal energy technologies present options to augment the electric grid.

To investigate building cooling and energy efficiency options, the University of Hawaii at Manoa’s Hawaii Groundwater and Geothermal Resources Center collaborated with scientists at Lawrence Berkeley National Laboratory through the U.S. Department of Energy’s Energy Technology Innovation Partnership Project (ETIPP).

Managed by the National Laboratory of the Rockies (NLR), formerly known as NREL, ETIPP supports remote, coastal, and island communities with technical assistance and energy planning to help them build more reliable and affordable energy systems. Communities apply for up to 24 months of technical assistance, and those communities drive the scopes and focuses of their energy projects.

University of Hawaii at Manoa joined the program in 2022 with a desire to explore geothermal options, and a new report from this project details the feasibility of developing shallow ground heat exchangers (GHEs) across Oahu and at a specific site on the island for cooling.

Geothermal heat pumps take advantage of relatively constant temperatures just under the earth’s surface, using GHEs to exchange heat with the earth. Through a system of looping pipes in the shallow ground, GHEs can move heat from a warm place to a cooler place, like how a refrigerator functions.

“High-temperature geothermal, which requires deep drilling, is required to produce electricity, but low-temperature geothermal such as GHEs, which can be accessed much nearer the ground surface, can be used for building heating and cooling, greatly lessening loads on the electric grid,” said Lawrence Berkeley National Laboratory’s Christine Doughty, staff scientist.

“I believe both types of geothermal have potential to be an asset to Hawaii,” added Nicole Lautze, founder and director of the Hawaii Groundwater and Geothermal Resources Center.

Determining Geothermal Cooling Favorability in Hawaii

In open-loop geothermal systems, wells are drilled to extract and inject groundwater, allowing the movement of thermal heat to and from the earth. These GHEs use cooler ground water from outside the system for the cooling process and expel the warmer water afterward.

In contrast, closed-loop GHE systems continually circulate a heat-transfer solution through pipes, which transfers heat to and from the ground via thermal conduction. Groundwater needs to have temperatures that are low enough to effectively cool buildings, and groundwater flow in a GHE system works to remove built-up heat.

Hawaii has far greater needs for cooling than for heating—meaning that GHEs would add heat to the subsurface and cause the systems to not function as desired. That is where groundwater comes in: It replaces heated water from the boreholes and maintains the functionality of the GHE system. Sufficient groundwater flow, then, is essential to the considerations for GHE deployment. GHE systems may not be deployed in areas with restricted watersheds or where there is subsurface production of freshwater. Therefore, closed-loop systems may be a more reasonable option in some locations.

Numerous factors help determine whether a community or business may consider GHEs. Areas with older homes may lack efficient energy systems, and some organizations, like schools or government buildings, may prioritize more adaptive heating and cooling. Cultural considerations are also very important, and a new NLR report incorporates Hawaii communities’ perspectives on geothermal.

Economic factors are another big consideration, with the expense of deploying a system versus energy savings playing into overall cost. Modeling revealed that electricity and energy transfer demand decreased, and such reductions contributed to cost savings. Longer loan terms may help ease deployment expenses for geothermal systems.

ETIPP researchers factored the above parameters into their analysis to develop favorability maps for closed-loop and open-loop GHE systems. They used specific geographic information system layers with 11 attributes—including elevation, geology, and soil permeability—to develop an overall favorability map for GHEs on Oahu.

For the site-specific feasibility analysis at the University of Hawaii at Manoa’s Stan Sheriff Center, researchers used a hydrogeologic model to analyze groundwater flow of a closed-loop system at the site. Restrictions on water quality—mandating that groundwater must be left in its natural state—diminished the available area for GHE system deployment across the island, while many coastal areas showed high favorability. Overlays showing potential customers and restricted areas sharpened the maps.

Geothermal Cooling Potential at University of Hawaii at Manoa

From the island-wide analysis, ETIPP analysis homed in and found that the Stan Sheriff Center at the University of Hawaii at Manoa, a building with a high cooling load in an area with lots of open space surrounding it, could make a good candidate for site-specific analysis of GHE technology.

Researchers used a hydrogeologic model to analyze a potential closed-loop system at the site. They modeled groundwater and heat flow, analyzed subsurface heat flow, and completed a techno-economic analysis.

Analysis without groundwater flow showed that the GHE system may operate normally in the first year, but heat buildup would increase water temperatures significantly after that, and without groundwater to sweep heat away, there would be increased chiller demand in years two through six. Modeling that incorporated groundwater flow—with similar conditions as the Stan Sheriff Center—showed that heat would be effectively swept away from the borefield, which would enable successful GHE operation for at least 10 years. Thus, including groundwater in analysis and planning—coupled with low interest loan rates and high capital investment—may provide economic benefits to the university.

Cold seawater may be an option for cooling-source systems, the analysis concluded, and such a system already operates at the Natural Energy Laboratory of Hawaii. The report authors encouraged further study.

As in Hawaii, ETIPP continues to help communities explore geothermal and other technologies to help meet their energy needs through in-depth, collaborative investigation of potential solutions.

“This ETIPP project established a strong collaboration with LBNL and the foundation for what I hope is additional grant funding to explore the potential of GHEs on the UHM campus and across the state to cool buildings and reduce load on Hawaii’s grid,” Lautze said.

The U.S. Department of Energy’s Energy Technology Innovation Partnership Project (ETIPP) is a community-led technical support program for coastal, remote, and island communities to access unique solutions and increase energy reliability. By uniting federal agencies, national laboratories, regional organizations, and community stakeholders, ETIPP provides tailored technical support to help communities achieve affordable, reliable solutions to their energy system challenges. This collaborative model leverages the combined expertise and resources of its partners to deliver comprehensive, practical solutions that align with local needs. Learn more about ETIPP.
