Controlled Green Roofs for Seismic/Wind Load Damping

Need to integrate forecast information into distributed real-time control systems.

What is the least expensive means for getting data from the Internet into the field

for real-time control?

•Move digital information “off the screen into the physical environment, manifesting itself as subtle changes in form, movement, sound, color, smell, temperature, or light. Ambient displays are well suited as a means to keep users aware of… general states of large systems…”

(Ishii et al:, 1998)

Ambient Information Systems

• “Ambient displays have the ambitious goal of presenting information without distracting or burdening the user.” (Mankoff et al. 2003)

Ambient Water Information SystemsGoal Information Conveyed to

IndividualTarget Outcomes

Reduce Consumptive Use Waste

Individual feedback on weekly cumulative water use, water pricing data, and/or system demand. Information regarding irrigation consumption best practice based on weather and/or climatic data. Indicating and alerting individuals to changes in local regulatory actions relative to consumptive use such as irrigation bans.

Reductions in consumptive use and changes in timing of use as a result of feedback and awareness of impacts.

Optimize Storm Water Control Usage

Information on how to optimize use of storm water controls that require individual participation (e.g., rain barrel, blue roof, or cistern management).

Optimal use of Rain Barrels or other controls which require operator control and decision making (e.g., drain or leave full) for volume control in urbanized areas.

Reduce CSO Impacts

Information regarding receiving water quality and CSO status in combined sewer areas.

Consumptive use changes based on direct impacts on receiving waters. These could include but are not limited to timing or other decisions about consumptive use and decisions about waste water quality (e.g., what do I send down the drain at a given time).

Express intents and values Express cost sensitivity Agents manage resources and decisions to

achieve intents and values Example

Washing machines or dishwashers could be deferred to times when use fits the individuals desired resource consumption intent

Irrigation controllers optimize user intents Reuse – balancing competing interests

Intelligent Digital Agents

Enable trading markets between consumers Collective bargaining between consumers and

bond holders What will the role of utilities be? Fundamental link between policy and technology
