The report assesses the current energy usage of the facility, provide options for reducing the amount of energy used, and evaluate the cost versus benefit of each option. Discussions of site specific concerns, financing options, general facility information, and an energy efficiency action plan are also included in this report. ACKNOWLEDGMENTS The Alaska Native Tribal Health Consortium (ANTHC) Rural Energy Initiative gratefully acknowledges the assistance of Patrick (PJ) Hanson, First Chief, the members of the Venetie Village Council, and Donna Erick, the former Council administrator. LIMITATIONS OF THIS STUDY The building modeling software AkWarm© was used to create a virtual representation of the Venetie Village Council Office. The model is then used to test the cost effectiveness of different energy efficiency measures (EEMs) like LED lighting and pump improvements. The AkWarm© software calculates the annual cost savings and payback period for the investment, and then ranks all EEMs based on their payback period. There are limitations using this software, which may affect the accuracy of the EEMs cost savings. This report should serve as a guide when deciding which EEMS to pursue further. All EEMs and installation costs should be verified with a certified professional in that field before construction begins. 4 OVERVIEW This report was prepared for the Venetie Village Council. The scope of the audit focused on the Venetie Village Council Office and includes an analysis of building occupancy schedules, building shell, heating systems, lighting, and other electrical loads. The Venetie Village Council Office was constructed in the 1970s and was recently outfitted with LED overhead lighting. The office building is approximately 800 square feet, and has a central meeting area and office spaces. Data was gathered on a site survey and interviews with members of the Venetie Village Council. ENERGY BASELINE Based on unsubsidized electricity and fuel oil prices in effect at the time of the audit, the total predicted energy costs are about $7,192 per year. This includes $3,109 for unsubsidized electricity, a calculated cost of $3,004 for #1 fuel oil, and an estimated cost of $1,079 for cord wood. The State of Alaska Power Cost Equalization (PCE) program provides a subsidy to rural communities across the state to lower electricity costs and make energy affordable in rural Alaska. The Venetie Village Council Office receives a PCE subsidy, reducing the cost of electricity from $0.90 per kWh to about $0.52 per kWh. Table 1 lists the predicted annual energy usage before and after the proposed retrofits for the Venetie Village Council Office.

The SIR shows how profitable a project will be; the higher the SIR, the more profitable the project. An SIR greater than 1.0 indicates a cost‐ effective project (i.e. more savings than cost). Note: the project’s SIR is related to the rest of the Energy Efficiency Measures (EEM) above and the calculation assumes that projects are completed in the same order as in the table. 2 Simple Payback (SP) is the estimated length of time needed to recoup the initial investment cost of the project. Note: this does not account for accrued interest from loans or any future changes in energy prices. The wood stove upgrade recommended above is one solution to balance residents’ needs, fuel efficiency, and improved air quality. There are numerous models available that will serve this purpose, and still meet or exceed the building’s current heating requirements. 7 Note: Wood stoves may contribute to poor indoor air quality. Long‐term exposure to poor indoor air quality may increase the risk of developing respiratory conditions, particularly in young children and elders. Steps should be taken to properly monitor and ventilate buildings with woodstoves, regardless of any potential improvements to the building shell. Burning dry, cured wood whenever possible will reduce particulate emissions at its source. Additional Recommendations (not included in Table 2) Window film: Applying shrink wrap film may reduce air/heat loss through the windows. Thermal curtains: Installing thermally insulating or heavy curtains may reduce air/heat loss through the windows. FACILITY DESCRIPTION Building Occupancy Schedules The building is used meetings and office space Monday through Friday 10:00 AM to 5:00 PM. There are about five to ten people in the building during operating hours. Building Shell The exterior walls are log construction. Each log is approximately eight inches in diameter. The roof of the building is log construction on the interior. The cathedral ceiling has about two inches of spray foam insulation and 5.5 inches of R‐21 fiberglass batt on top of the logs. An exterior roof covers the insulation materials. The cathedral roof cavity is not sealed, so the fiberglass insulation is likely to be damaged from exposure to moisture. The floor of the building is constructed on short pilings. There is approximately 5.5 inches of R‐21 fiberglass batt between the exterior and interior subfloors. The subfloor cavity is not well sealed, so the fiberglass insulation is also likely to be damaged. Typical windows throughout the building are double paned with wood framing. The windows are most likely filled with air. The Venetie Village Council Office building has one entrance door. The door is fiberglass with a polyurethane core. It does not have a window. The door handle is missing. Typical roofing structure in Venetie. 8 Heating Systems The heating systems used in the building are: Wood Stove Nameplate Information: Barrel stove (55‐gallon drum) Fuel Type: Cord wood (spruce) Input Rating: 32,292 BTU/hr.

The payback for the implemented EEM’s is approximately 12.1 years. ANTHC is willing to assist the community with acquiring funds to complete the scope of work recommended in this energy audit. There are several options for financing energy efficiency projects within the State of Alaska. These include the use of grants, loans, and other funding opportunities. Below is some information on potential funding opportunities. Energy Efficiency Revolving Loan Program – This is a loan administered by the Alaska Housing Finance Corporation (AHFC) for use by any applicant who is also the owner of the building where the work will take place. It provides a loan for permanent energy‐efficiency projects with a completion window of one year. Sustainable Energy Transmission and Supply Program – This is a loan administered by the Alaska Energy Authority (AEA) for a government, business, or other organized body of people. It provides a loan for energy‐efficiency or power transmission or distribution projects. USDA‐RD Communities Facilities Direct Loan & Grant Program ‐ This is a loan or grant provided by the US Department of Agriculture – Rural Development (USDA‐RD) for any essential community facility in a rural area. It provides a loan or grant to develop essential community facilities with upgrades or equipment for improvement. 10 MEASUREMENT AND VERIFICATION The actual results of these recommendations can be measured by collecting and monitoring energy use. This information is available on the monthly bills provided by the local electric utility and the local fuel oil supplier. Collecting data and performing a historical comparison is the simplest method of validating the energy and cost savings seen by the measures. Additionally, active remote monitoring systems are available that can collect and store data regarding energy and fuel usage. These systems allow the user to track the usage in real time and can be shared more easily with partners across the state. 11 APPENDICES Appendix A – Energy Billing Data 1.
