Reducing the electrical load in NYCHA buildings

Sustainability Problem: Energy

The New York City Housing Authority pays resident’s utility bills in 27 developments, a total of 166,952 units and 1,979 buildings, which add up to $180 million yearly. Demand has been the main driver of the utility cost increase witnessed by NYCHA in the past year, with consumption remaining stable. The authority faces many deep challenges, including increasing maintenance demands, declining funding, and aging housing stock, which make extensive energy retrofits difficult to fund. In this context, NYCHA would like solutions to manage electricity demand and in turn reduce electricity costs without having to replace building systems entirely.

 Technology: Smart sensors on window-mounted air-conditioning units

  • To cut down on usage, H.T. Lyons and Consolidated Energy Design proposed installing sensors that regulate the air-conditioning compressor during peak energy usage, when watts are more expensive, while keeping the unit on and residents comfortable.
  • The companies estimate that this technology can reduce energy demand of air conditioners by 40 to 60 percent when demand is highest.

Stakeholders:

  • NYCHA and its residents
  • Utility company
  • Local government
  • T. Lyons and Consolidated Energy Design

Implementation

  • NYCHA is currently working with H.T. Lyons and Consolidated Energy Design to implement their solution as a small-scale pilot projects that will range from 3 months to 1 year
  • The companies will install the solution at their own expense to demonstrate the benefits of the solution
  • At the end of the pilot, the Authority will evaluate the impact of the technology and, if successful, it may be applied NYCHA-wide

Tech helping to reduce manure odors from Swine Industry is creating Circular Economies.

Sustainability Problem: People surrounding swine industries have lived for many years under the externalities of odors and water contamination because of the bad practices in manure treatment.

pigpicEach “pound” or “kilogram” of manure coming from pigs or cows has an interesting potential to generate energy for lighting, transporting, and heating/cooling. In the City of Santiago (Chile), 1,6 million of swines live in factories for supplying meat for the country as well as for exporting. The 1,600,000 swines, considering sizes and manure production, were estimated as an equivalent 16 MW of energy generation, considering 9 MW for thermal energy (heat), and 7 MW of electricity generation. Today, the swine industry understood that revenues coming from energy sales are extremely relevant to their business models, therefore, instead of expending money in manure treatment, they started to install “biodigester + Generators”. However, one big concern came up, there was a byproduct called “digestate”.  The digestate is a highly nutritive product for agriculture. If well managed, it can be used as a fertilizer. Bang! Now the swine industry, after many years, realized that all the externalities (odors) created to people living around the swine industry, can be turned into an opportunity.

16-farmgen-anaerobic-biodigestor-ashley-cooper

The model of the circular economy can be summarized as follows. First, the swine industry sale meat. In addition, they take the manure and put it in the biodigesters, which generate electricity and heat (a new revenue), but also create digestate.

The digestate is treated and then provided (sometimes for free) for farmers cooperative in the area as a fertilizer. The farmers install pipelines to transport the digestate (sometimes swine industry contribute in the investment), and farmers production improve considerably because of the “natural” fertilizer. In conclusion, farmers reduce cost by not buying fertilizer and also increase revenues by creating additional value for their products.PBPO 2006 The benefits of agricultural small-scale biogas plants

3 steps for deploying the technology.
1.- Estimate energy potential identify the stakeholders involved in the ecosystem of the swine industry.
2.- Explains the benefit of using a biodigestor and a fertilizer pipeline. COnvince a venture capital or an investment fund to cover your expenses! Today the energy business in Latin America is pretty reliable!
3.- Install the technology, bring some cool operator from Europe or train people from your country, and start producing energy, reducing cost, providing fertilizer to farmers, and creating a cleaner city for all the neighborhood around the industry!

Using New Technology on Diesel Burn to Improve Air Quality

1:

Area of sustainability category: Air Pollution

The air pollution is a severe problem for many countries including both developing and developed ones. It is worth noting that diesel emission is one of the main causes of air pollution in urban areas. Typically, in London, people have started taking actions and citizens want to change the current situation so bad that over 29 million people have signed for an action on diesel emissions in urban centers where have the highest car concentration.

 

2:

“New Technologies Which Could Improve Urban Air Quality”, website: Policy Exchange, https://policyexchange.org.uk/6-new-technologies-which-could-improve-urban-air-quality/

  • The ezero1 technology can improve the fuel combustion cycle by adding additives
  • Small amounts of hydrogen added into the vehicle air intake can provide a more efficient burn of fuel
  • This technology can be applied on existing cars and vans
  • This technology is produced by UK developer CGON and is available commercially

 

3:

  • Private car driver who wants to reduce carbon footprint and enhance fuel efficiency
  • Tourism companies such as car rental company, bus companies etc. which want to save fuel bills to lower the operation costs
  • Car manufacturers who want to enhance engine performance and provide a more sustainable car model
  • Municipalities which want to change current sever air pollution problems

 

4:

  1. The company may conduct an analysis to find where car owners are huge and people’s awareness of air pollution is high. Thus, CGON may find the best target for launching this product in the early stage.
  2. To further attract potential clients, CGON should proactively seek opportunities of attending Auto show, air pollution or energy-related conference to increase people’s awareness of this technology
  3. CGON may also seek for partnership with city governments and tourism companies. For example, CGON can take part in government’s environmental enhancement projects. CGON can offer discount and free installation if large volume orders are placed.

 

 

People & Civic Tech in NYC.

Sustainability Issue.

People living in Manhattan now have access to public wi-fi through LINK-NYC. In addition, people living in big cities can observe how solar tech is used for multi-purposes and at different scales. However, most of the population have neither access to tech solutions, nor proximity to deployable technologies to solve day-to-day problems.

Opportunity.
In 2017, after many weeks of civic engagement activities, starting by training sessions about tech opportunities, building advisory teams, and figuring out potential economics improvement by using Tech, the program Neighborhood Innovation Lab (NIL) was launched in Brownsville, NY. NIL seeks to enhance economic development through technology, but it also compromises the deployment of two civic technologies during the implementation of the strategy.

Osborn Plaza, Brownsville, Brooklyn, New York.

Solutions deployed

Technology Objective: Show how the technology can be part of our daily routine, as well as to familiarize people to new devices using internet of things (IOT).
Bigbelly solar-powered smart waste and recycling system, which can hold up to five times the amount of a regular trash bin and uses sensors to notify maintenance crews when it is full.
Soofa smart benches, which use solar power to offer free charging for mobile devices.

Where and How?
Big belly could be a potential solution to remote or public areas, while the Soofa Smart bench, can be deployed at any plaza if a cost-benefit analysis supports the investment. Most of the tech solutions for civic engagement require the use of the internet, for example, big-belly to report full capacity.  Therefore, sites, where Link NYC is already installed, are potential areas to take advantage of the use of public wi-fi.

Steps for Implementation.
1.- Mapping areas where tech could create a new economic development opportunity. Create a tech strategy, invite partners, create an advisory team, and get support from the Mayor´s office of Tech + Innovation.
2.- Solve people, SME´s, and other´s problems, if possible, by implementing tech solutions.
3.-Deploy civic tech in the area to create engagement in the civil society.

The great pacific garbage patch

Sustainability issue:  The great pacific garbage patch is a water and waste pollution issue. This patch of marine debris located in the pacific ocean has been stuck there for years due to the pacific vortex which keeps it circling the waters

  • Instead of chasing after the waste, the “Ocean CleanUp” will instead deploy barriers that use the same water currents that makes the waste stuck in place, to collect that same exact waste.
  • Sea life will not be impacted as only lighter than water plastic objects will get caught in the net.
  • Over 10 years, these nets can clean up half of this waste.

Organizational stakeholders: International Coastal Cleanup, Trash Free Seas, Greenpeace International

3 steps to deploy technology: – Introducing the idea to the organizational stakeholders who can fund it, soliciting help and materials from individuals if this is to be done from volunteer work (already being done), sensitizing populations so they are more willing to help when it comes to waters that we all share and that do not affect their immediate lives.

Bladeless wind turbines trialed

f0da4b6f-821d-4653-b22e-b7dd5d997fa7-1020x612

1. Sustainability Problem

Energy: Global energy demand continues to grow, and renewable energy technologies are often less acceptable than fossil-fuel technologies because of the cost to manufacture and concerns about unintended impacts. Wind turbines, in particular, are often opposed because of noise pollution, shadow flicker and bird strike.

2. Technology Article Summary

Article:
Can bladeless wind turbines mute opposition?

by Dominic Bates
Published 6/1/2015 on theguardian at http://www.theguardian.com/sustainable-business/2015/jun/01/can-bladeless-wind-turbines-mute-opposition

  • Spanish company Vortex Bladeless has developed a wind turbine that captures close to 40 % of wind energy  without the use of blades.
  • The turbine uses the principle of aeroelastic coupling: wind currents form whirlwinds or vortices in contact with the structure, a single mast mounted on a frictionless magnetic bearing.
  • Vortices cause the mast to oscillate, a movement that increases exponentially as the frequency of the vortex approaches the resonance frequency of the structure. This mechanical energy is easily converted to electricity.
  • The structure is cheaper to produce than a conventional bladed turbine, has no wearing parts, is much quieter and is not expected to harm birds, so is poised to overcome the most significant arguments against wind turbine installation in the UK.
  • The turbine has not yet been produced to scale, but Vortex Bladeless hope to release a 100 W, 3 metre model and a 4 kW, 13 metre model in the next 18 months.

3. Organizational Stakeholders

This technology is initially intended for distributed generation. In this phase it might affect the following stakeholders:

  • Communities living off-grid in Africa and India
  • Homeowners in the UK interested in domestic generation
  • Policymakers considering restrictions on height of domestic turbines
  • Environmental and community groups including RSPB and CPRE

4. Deployment

The next three stages in deploying this technology could be:

  • Vortex Bladeless: develop 100 W and 4 kW models for market
  • Policymakers: reconsider the current 11.1 m height restriction on turbines in residential areas
  • Policymakers: exempt bladeless turbines from subsidy withdrawals designed to discourage bladed turbine installations
