• Added 7040 Watts of Solar Photo Voltaic Panels - 32 Sunpower 220 Watt Panels and a 6000 W Sunny Boy Inverter
• Added 91 Bales of Cellulose Insulation Blown into 2 of 3 Attics - Self installed - R values now 70 -100 in attic the areas serviced
• Replaced Windows with Triple Glazed Low - E - R values now 9+ on the glass.
• Added Thermal Insulating Window Covers Inside- Increased the R value of the Window Openings to ~ 14
• Purchased and use an INFRARED narrow beam Laser Thermometer to identify and correct insulation issues.
• Added 6 Solar Tubes for Day-lighting (Large ones - 22” (3) and 14” (3)) - Wonderful Natural Diffuse Light Saves Electricity
• Replaced Gas Furnace with 95.5% Efficient Model - Smaller than original due to added House Insulation
• Added Evaporative Cooling - $95 net cost - Self engineered and self installed - Cools on ~1/6 Elect Power of A/C
• Replaced 102 Incandescent Light Bulbs with Compact Florescent Design - out of 103 (refrigerator CFL not available)
• Ventilated Attic by adding Ridge and Soffit Vents - Soffit - Self Install
• Wrapped Water Heater in 3” Insulating Blanket - Self Install
• Keep Water Heater on Low (“Warm” not “Hot”) Self Adjustment of Setting - - I do not need “HOT”.
• Lightened Color of Roof and Outside Walls - when replacement was otherwise needed - Extends Paint and Shingle life and reduces cooling need in summer.
• Installed Composter - made from recycled materials - as a first step in Permaculture
• Added Solar Clothes Dryers (2) - Self Install, (Clothes Lines)
• Added Solar Stove - Self Apply - Tastes Good!
• Added Solar Bird feeder - Self Install, Night Light is nice on the birds … as they eat.
• Added Solar Clock (Sun Dial) - Self Install,
• Added Solar Seed Sprouter - “Cold Frame” - spring sprouting (using recycled windows and rail ties)
• Use USED Bicycles for MUCH/MOST of daily transport. “Cycle Recycled Cycles” It is Doubly GREEN... saving the Embedded Energy of the construction of a new bicycle.

When not riding bicycles, Museum vehicles are:

1. 2007 Prius (soon to be plug-in so it will use the Solar Power from the PV system)
2. 1996 Geo Metro - High MPG

Planned further Museum Energy Improvements:

1. Add another 55 - 70 bales of Cellulose Insulation:
   • Lower Level Walls - blown into cavities between the Foundation and the Inner frame wall
   • Attic over kitchen, adjacent and connected to Garage Attic ...to R-100
2. Wrap Exterior Frame areas (1400 Ft Sq) with DRYVIT - 4" Foam with Stucco - adds R-20 or a Borax based insulating coating (like on the Space Shuttle tiles)....under research for home application.
3. Trim the TOPS of Adjacent Neighbors Evergreen Trees to regain Solar Tempered functionality ... of home/museum. A SOLAR ACCESS AGREEMENT HAS BEEN SIGNED FOR THIS. This (#3) facilitates:
4. Grow of the Museum Space by 450 Sq Ft on SouthEast with High Insulation Walls allowing Sun Room to be built above to gain Passive Solar heating for the whole structure. and finally:
5. Develop a Organic Garden where Green Grass is now - to produce locally the fresh foods for the staff.

When these improvements are completed, the museum will be far beyond the Net Zero status on Carbon Footprint ... which it is now. It will achieve a status of making structure, transportation, and all living areas become net zero for the museum and staff.

The concept of a Combined Museum/Home also has energy saving aspects:

1. No Commute to work for Museum Workers
2. Making the Museum become Net Zero Carbon also, at the same time, makes museum staff homes be net zero.

The concept of Far More PV than the electric bill would demand ... is what funds the current Net Zero status, matching the low remaining Natural Gas Usage on a BTU for BTU basis (measured at the Wellhead/Mine). It also is what will support the Plug In vehicles for the transportation after the other planned energy improvements are complete.

Current Annual Natural Gas Usage measured (for 3250 ft sq) in 2007 was 432 Therms. In 2008, current completed actions in late 2007 should reduce this to about 300 - 350 Therms. Planned actions should further reduce it to about 100 therms for the full year (on an expanded 4150 sq ft). In 2008, the over production of Solar PV power should be approximately 7,500 KWH.

Looking at 2008, the 350 therms usage represents a BTU at the wellhead of 37,852,500 BTU (350 Therms x 103,000 BTU/Therm x 1.05 (loss in production/transit)).

The 2008 Surplus 7500 KWH represents a BTU at the Coal Mine of 10,236,000 BTU (7,500 KWH x 3412 BTU/KWH x 4 (Coal Electricity IN-Efficiency Factor Mining/transporting/generation)).

Thus, the Museum will have an annual Surplus of 27.6 million BTU. This translates to 8100 KWH which will drive the Tesla about 32,000 miles or the Aptera about 60,000 miles. It will be hard for staff to drive those amounts ... since staff prefers to ride recycled bicycles! However, as staff is aging, and Tesla and Aptera cars are very uniquely fun ... staff may do more more auto travel ... Cleanly powered by the SUN!
