Additional Measure – TTC Energy Efficiency Building Improvements Early in the process of coordinating with the Tuntutuliak Traditional Council on these projects, TTC informed us they had grants through Alaska State CCED for making building improvements to two of their buildings. TTC clarified to ABSN that energy efficiency improvements were among their top priorities for utilizing their CCED grants. They identified new windows and heating systems for the Community Building and Public Safety Building. Seeing this as a fuel saving and match funding opportunity for the VEUEEM grant, ABSN coordinated and consulted with TTC to help them move forward in utilizing their building improvement grants to the achieve long-term energy savings. 4 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’07-’08 Final Report West Region - Tuntutuliak The windows in the TTC community building were old, double-pane, wood framed and leaky. Several would not close entirely and had moisture trapped between panes – demonstrating compromised thermal breaks. ABSN consulted with TTC to assist them in selecting and ordering low-e, triple-pane windows and trim package for their 3,900 sq ‘ community building and 544 sq‘ public safety building. This measure will reduce air leakage and heat loss. ABSN coordinated purchase through a large weatherization supplier to obtain highly competitive materials and shipping prices. Existing Boiler system in the TTC Community Building Existing single-pass cast iron boiler A single thermostat downstairs controls heat for the entire 2-story building, at times leaving the upstairs too cold and the downstairs warm enough to need open windows for cooling. 4 zones (one not pictured) are available for flexible heating control, but only one zone is controlled by the single T-stat. VEUEEM funds were also used to coordinate a heating retrofit site visit with Tundra Heating of Bethel to assess the TCC building for installing an energy efficient Biasi boiler system. The system offered by Tundra Heating is a redundant system using two Biasi boilers, circulator zone heating instead of zone valves and outdoor temp sensing controls. Each boiler will be able to carry the heating load independently other than the very coldest of the cold days at which time both boilers will kick in to meet heating load. That way the boilers will be sized for the building for maximum effici ency. Biasi boilers reach high 80’s for AFUE energy efficiency, which does not give credit for the low -standby losses and outdoor resent controls for these boilers. Biasi boilers employ a three -stage heat exchange system, rather than traditional single-pass, cast iron boilers. These boilers are lower mass and can be direct vented through a wall if workable, to avoid chimney-stack, heat-losses. Also, Biasi boilers can cold-start which means the system does not have to run at operating temperature at all times during all seasons. It only fires when there is a call for heat from a particular zone, and then only creates hot water for the zone that has called for heat. Also, outdoor temperature sensing controls will allow the boiler(s) to lower water temperature during warmer times. All in all, this system will employ some of the best technology and local designer/installer savvy for optimum energy efficiency. We expect the new system will use 30% – 40% less fuel than the existing system and run with fewer maintenance issues. Materials and labor for these measures will be funded by TTCs building improvement grants, with the measures planned for completion in the spring of ’09. Since these measures have yet to be completed, and savings figures are not currently available, no fuel savings figures for these measures appear in reported savings estimates. 5 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’07-’08 Final Report West Region - Tuntutuliak Clinic Materials Installed Quantity 2-lamp electronic ballast, (2) 25 watt T8 lamps 9 4-lamp electronic ballast, (3) 25 watt T8 lamps 4 CFL-14 W 2 CFL-20 W 4 CFL-27 W 3 • Pre-retrofit energy use: 1959 watts • Post-retrofit energy use: 912 watts • Energy savings projection: 1047 watts • Pre-retrofit to post retrofit energy reduction: 53% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 1750 Hours/year (Est.) $952.77 148.60 $341.78 4 Hours/day $544.44 84.91 $195.30 7 Hours/day $952.77 148.60 $341.78 10 Hours/day $1,361.10 212.29 $488.26 Note: All 4-lamp fixtures de-lamped to three 25 watt T-8 lamps each for additional savings.
