Monitoring, Instrumentation and Validation
Energy Neutral Building Performance Comparison Study: In collaboration with PROJECT Frog and MKThink, HNEI is deploying and instrumenting several high performance, energy neutral or Net Zero Energy (NZE) buildings on Oahu and Kauai to evaluate their performance in differing environments and different usages. The performance (energy and comfort metrics) of these structures will be compared to standard buildings in Hawaii and used to validate predictive models. This project has been initiated in cooperation with the State of Hawaii Department of Education in an effort to evaluate building performance and to make recommendations for future energy savings and comfort enhancement.
Monitoring and Field Performance Validation: HNEI and the UH School of Architecture’s Environmental Research and Design Laboratory (ERDL) staff have partnered with Forest City Hawaii to instrument, monitor and evaluate energy consumption profiles in housing units and to determine performance of energy efficiency measures in a residential setting.
State of Hawaii Department of Education Facilities Energy Audit and Inventory Study: HNEI is facilitating a pilot project with the State Department of Education to monitor, evaluate and assess specific school facilities using a range of DOE-defined criteria that includes environmental conditions, energy use, comfort and other human factors related to healthy learning environments. HNEI will participate as the administrative lead utilizing the expertise of MK Think as prime contractor. The key deliverable to the DOE will be an analytic model they can use to objectively prioritize building and campus improvement projects using their own sustainability criteria.
Small Scale Wind Turbine Analysis: In collaboration with the Golden Gate Park Conservancy, HNEI has deployed five small scale (1kW) vertical axis wind turbines that are being monitored to evaluate performance for distributed applications. This work, conducted at Crissy Field Center, an environmental education center for youth located in San Francisco includes development of a web-based dashboard that monitors all of the sustainable features of the building: energy flow in and out by end-use, water, comfort and weather.
Energy Savings Retrofit
Advanced Deep Retrofit Programming for Local Governments: HNEI is collaborating with the County of Kauai to develop a performance contracting model (Energy Savings Performance Contract or ESPC) with aggressive goals to achieve 30% beyond a conventional energy savings retrofit. HNEI is working with consultants that specialize in advanced technologies and performance contracting protocols to ensure a successful outcome in Kauai, and to help establish a template for future ESPC projects in the State.
Advanced Building Research Platforms
Energy Neutral Test Platforms: The HNEI is leading this study, in collaboration the Office of Naval Research to analyze the performance of these energy systems. HNEI has deployed three pre-engineered test platforms, created by California-based Project Frog, Inc., that incorporate passive design elements to decrease energy demand, and use photovoltaic system to feed renewable energy to the structure. The design reduces energy consumption, construction waste and operating expense, while providing spaces that are adaptable for a variety of uses. Two of the platforms are deployed on Kauai and one on Oahu.
Off-Grid Net Zero Energy Visitor Center: In collaboration with Anderson Anderson, a San Francisco based architecture firm, HNEI is deploying a turn-key, off-grid Net Zero Energy Visitors Center for the NPS in Volcano National Park on the Big Island. This structure will demonstrate performance of advance building design and state-of-the art energy technologies including photovoltaic solar energy, advanced lighting, and energy storage for off-grid applications.
Building Simulation and Energy Modeling
Education and Training -- Building Simulation and Energy Modeling Skills: In collaboration with the School of Architecture’s Environmental Research and Design Laboratory (ERDL), HNEI is building core competencies on the UH Manoa campus in building simulation, modeling and performance based design. The entities collaborated to develop the State’s first professional level academic course curriculum in energy design simulation to provide students and design professionals a new professional skillset required to meet Hawaii’s increasingly stringent International Energy Conservation Codes.
