Situated on the shores of Kahuwai Bay in Kailua-Kona on the Big Island of Hawai'i, Kona Village originally opened its doors in 1965. It sits on the site of an ancient Hawaiian fishing village, Ka'ūpūlehu, which was vacated after the 1801 Hualalai lava flow. Lava covered much of the area, but spared the anchialine ponds which remains a registered natural preserve. Kona Village is known for its unique Polynesian thatched “hales”. The iconic resort was heavily damaged by the 2011 Japan Tsunami.

InSynergy Engineering, Inc. provided the mechanical, electrical and fire protection design work for the complete reconstruction of the original Kona Village into a new 81.4 acre, five-diamond resort. The project included 150 resort units, consisting mainly of single-unit hales, several two-unit lock-off hales, four family suites, and two presidential suites. Six of the original Kona Village hales were also retained and completely renovated. The resort amenities include two fine dining restaurants along with other food and bar venues, a spa, fitness center, children’s center, cultural/education centers, and two large water feature pools. The resort also includes a stage and luau for both resort and non-resort guests.

Exterior work included coordinating the domestic water, pressurized sewer, fire protection, well water, R1 and RO water, chilled water, and propane distribution along the roadways from a new central chilled water plant and other generation facilities to the end use points. Electrical support included assisting in sizing of the electrical power distribution loads, step-down transformers and switchgear at each service building to each hale, suite, and common area building, and coordinating the IT services requirements and exterior IT distribution. Other exterior work included site, roadway, and pathway lighting, R1 recycled and RO well water for irrigation and water features; propane for the tiki torches and fire pits, and supporting electrical interconnections for a third-party Power Purchase Agreement net-zero PV system. InSynergy Engineering, Inc. also prepared a mechanical and electrical engineering infrastructure feasibility/sustainability study for the original site development masterplan and implemented and documented the sustainability features to achieve certified LEED v.4 Gold for the Moana restaurant, Spa, and Employee Village.
