This entails identifying the course of action in implementing both the conservation methods and investment stratgies with respect to on-site water and energy management by formalizing and analyizing the demands and supplies of each buildings on site .

Austin, TX 78724

This report ‘s central objective is to seek ways to close the gap between the on-site water and energy demands, and the on-site renewable potential supplies of water and energy.

3. Further and refine the current understanding of the monthly usership demands by scrutinzing the utility bills of the past and attempt to size and design, accordingly and accurately, and with a satisfactory safety factor, the overall potential on-site renewable supply systems of water and energy.

a typical water balance page what are some of attributes of the building related to water design ?

is this building water balanced (supply & demand) ?

how much sun and how many kWh do I anticipate to generate from that much sun monthly and annually?

what are some attributes of the building and its location related to solar design? what requires a lot of energy on monthly basis ? (shows estimated use pattern)

what requires a lot of water on monthly basis ? (shows estimated use pattern)

what would the monthly net water storage have been, had we x amount of water storage capacity and had captured every drop of rain in the last 5 years?

how much rain and how many gallons do I anticipate to collect from that much rain monthly and anually ?

when could this building have shared its water supply excess? had we increased the size of the tank, could there have been more months when this would have been possible if the demand stayed the same through out?

Amount of garden growing space needed for a person = 100 sq. ft. - enough for 3 people Fish = tilapia and catfish Good plants: -Any vegetable suitable -water hyacinths (water -lilly pads shade water -underwater oxygenating

for eco region cleaning, good for human area) and prevent algae plants: anacharis, myriophyllum, cabomba

1. Water begins clean in human swimming area. 2. Water passes into fish/water plant area. Fish and other organisms (snails) keep away algae. Excrement becomes food for plants as water moves on. 3. Water enters sloped beds. Soil creates excellent cleaning sponge and plants make it faster and better. Food results from dirtying (fish) and cleaning (plants) of water. Add earthworms to sloped beds for fish food or have worms in compost from garden scraps.

weatherization or prevention of pipes from breaking due to the cold weather

are there any other strategies to increase on-site power supply?

is there a real possibility of long term contract that eliminate the huge upfront cost related to Solar PV?

can an appropriate PPA (power purchase agreement) provider for the center be found? does Austin Enegy want to borrow some of the center land (ex : air strip) on a lease for solar power gneration as part of their investment under the smart grid program ?

safety factor 1. which month are we in most trouble because it rains the least historically? January 2. how much rain do we currently collect in jan? 3267(AGBDH) + 741(factory) + 624 (Solar D) = 4632 gal

4. we if =

what is the amount should be collecting in jan our safety factor was 1.5? 14313

5. what much more rain should we collect in janaury? = 14313 - 4632 = 9681

negotiation point: is there any part of the installation process that can be done as an in-house job?

1) larger rain collecting roof 2) larger storage 3) proximity sharing

3. what is the overall site water annual demand in jan? = 9542 gal

if they do, are they wiling to provide some PV cells for the buildings on-site?

based on that understanding, it is possible to address the overall “steady state” of the site by prioritizing individual building in terms of its demand and applying both conservation methods and investment strategies to them one by one set forth in this document.

Theodore Roosevelt is credited for saying “Conservation means development as much as it does protection.” It is anticipated that when conversation strategies and investment strategies go hand in hand, they will provide a condition the most catered to the most growth in onsite renewable supplies and also the overall scale of the steady state reached between the on-site demands and the on-site supplies.

In order to take a step toward even greater and more holistic understanding of our use and the source of our two fundamental types of availabe supplies on site, we need to examine the water and energy bills and identify our use patterns both individually and collectively.
