NEWater is tackling Island Nation’s Primary Challenge

NEWaterDemographics

1) Sustainability Problem:  Singapore was ranked first among countries with the highest risk of high water stress in 2040, according to the World Resources Institute. Water security is the national priority in Singapore as half of its current water supplies imported from Malaysia.

2) Technological Solutions: Recycled Sewage NEWater is tackling an island nation’s primary challenge along with the desalination and efficient rainwater catch. NEWater created by the country’s public utility board (PUB).
– The $170 million plant can produce 50 million gallons of NEWater a day and will supply the PUB water for 25 years.
-Through a four-step series of barriers and membranes, wastewater is made free of solids, microorganisms, and contaminants resulting in potable water supplies for use by humans and industry.
-NEWater will be able to supply up to 40 percent of Singapore’s total daily water demand, up from 30 percent, with the opening of Singapore’s fifth NEWater plant in Jan 2018.

3) Key stakeholders and their role in the implementation:

– Singapore Government support and encourage private sectors to partner with the PUB  and regulate water consumption through price and financing innovations

-Financial Institutions-Financing New NEWater plants

-Educate consumers water system and actual cost of water

– Citizens consume water wisely

4) Steps Deploying Technology:

-Build prosperous environment for the utility companies to use a technology and financial institutions finance utility companies
– Within Public Private People’s Partnership educate each stakeholder how water scarcity could negatively influence whole system (energy, food, and economy)

 

I recommend other cities facing water challenges should duplicate project (Riyadh, San Diego, Brisbane, etc.)

Stanford District Energy System cuts GHG emissions 68 percent and fossil fuel 65 percent #BT2443

1-stanford

1) Sustainability area(s).

Cities consuming over 70 percent of global energy use and, producing 40 to 50 percent of greenhouse gas emissions worldwide. In some cities, heating and cooling can account for up to half of local energy consumption. Any solution for the climate and energy transition must address sustainable urban heating and cooling, as well as electricity. One of the least-cost and most efficient solutions for reducing emissions and primary energy demand is the development of modern (climate-resilient and low-carbon) district energy in cities.

2) Sustainability Technology:

The combined new system – Stanford Energy System Innovations (SESI) – makes Stanford one of the most energy-efficient research universities in the world.

-SEIS represents a transformation of university energy supply from a 100% fossil-fuel-based combined heat and power plant to grid-sourced electricity and a more efficient electric heat recovery system.

-High-efficiency new-building standards and improvements to existing buildings, a high-voltage substation, state-of-the-art solar arrays and a new central energy facility (CUP) that incorporates the largest heat-recovery chillers ever installed in the U.S

-SESI uses a combination of heat recovery, low-temperature hot water distribution, and thermal energy storage to reduce campus greenhouse gas emissions by 68% and drinking water use by 15%

-Technology roadmap for building heating and cooling

3) Key Stakeholders

-City stakeholders- Include their plan
-Government agencies-Legislate and help private sectors to participate
-Civic society- Connect and partnership with the stakeholders
-Property owners-Able to join or innovate DES
-Financial Institutions-Finance DES projects

4) Steps Deploying Technology:

Public-Private People’s Partnership is the key to successful deployment of the project.
– Within the city, planing decide to financial aspects
– Build a community and infrastructure and educate public
– Within Public Private People’s Partnership leverage project within significant cities

Although DES is common on university and college campuses and more accessible to regulate, it’s possible to duplicate Stanford model within major cities. Current DES powered by mainly Fossil Fuel for changing that financial institutions and state, city policies will play an enormous role.

Affordable and Mobile ALPOD House #BT2443

1) Sustainability area(s).

Most of the Mega-Cities facing issue affordable and smart buildings due to growing urban citizens. Majority of cities designed for fewer people.

2) Sustainability Technology: Futuristic Aluminum AlPOD Houses by James Law

-A distinctive feature of the AlPOD project is its potential to be stacked into a uniquely designed multi-structures to accommodate ever increasing populations and lack of available land

-Explores modular construction based on creating a flexible and open-plan living space

-Affordable about 65000 USD

-The aluminum house has multi-faceted advantages of being lightweight, durable, corrosion resistant, and impervious to fire and wind as well as its ability to dampen noise and insulate against heat and sound.

– Lightweight also enhances mobility, allowing a home to be moved from one place to another comfortably and conveniently without dismantling or reconstructing facilities.

-Moreover, aluminum can be recycled, making it a green, earth-friendly building material.

3) Key Stakeholders and their role in the implementation:

-City stakeholders- Include their plan
-Government agencies-Legislate and helping private sectors to participate
-Civic society- Connect and partnership with the stakeholders
-Citizens of the city-Live in the houses
-Financial Institutions-Finance

4) Steps Deploying Technology:

Public-Private People’s Partnership is the key to successful deployment of the project.
– Within the city, planing decide to finance aspects
– Build a community and infrastructure
– Within Public Private People’s Partnership leverage project within significant cities

Since one out of six people today in the world live in a migrant slum, this number will raise within few decades one out of three. I believe that this ALPOD housing could bring a progressive solution to this issue.
