12 essential aspects of green cities by Paul Hewins.

Great article by @Paul Hewins that was posted in Boston.com and Boston Globe today. As a member of the Urban Sustainability group, I have had discussions on green cities and smart cities, which relates to the key points that Hewins listed. As we transform into the digital world, we’re also looking at a greener world with environments that improve our quality of living – Erwin Chiong

Here’s the article by Paul Hewins:

12 essential aspects of green cities

For the first time in world history, more people live in cities than in rural areas. And that trend is not going away. By 2030, the UN expects that 60 percent of the world’s populationwill live in cities, and big cities will only get bigger. The good news is highly dense areas can be far more efficient settings, requiring fewer resources for more people to live. (Think of the reduced energy needed to move each person on a subway than in a car.) The challenge is to maximize the green potential of all elements of the city and its inhabitants.

With that in mind, here are 12 essential aspects of the green city of the not-too-distant future:

1. Infrastructure promoting transit, walking, cycling and other alternatives to car use. The green city will require an extensive system of public transportation, bike lanes and other infrastructure supporting car-free mobility, while also having places to work, live and socialize in close proximity. Offices will be built with green commutes in mind; think bike racks (plus showers and changing rooms), electric car charging stations, prioritized car sharing parking spaces, and easy access to public transportation. In Boston, the Longfellow Bridge is being rebuilt with wider sidewalks for pedestrians, making the walk to work simpler and safer.

2. Highly energy-efficient buildings. Buildings will use little energy, thanks to very good insulation levels in walls, ceilings and floors, and with high-efficiency windows and an optimized building orientation to minimize heating and cooling needs. In Northeast cities, there are huge opportunities to retrofit older buildings that are inefficient. A local example of this is the recent modernization project we completed at the 180-unit Lyndon B. Johnson senior housing apartments in Cambridge. The retrofit resulted in a 50 percent reduction in energy use at the property, as well as onsite renewable energy generation from rooftop solar voltaic panels that provided 18 percent of the electrical needs, as well as a solar collector built into the building’s skin to provide heat. The complex will also save $255,000 per year in energy costs and reduce the Cambridge Housing Authority’s carbon footprint by 2.5 million pounds per year.

3. On-site energy generation from such renewable sources such as solar, wind and geothermal energy. Buildings will capture solar, wind and geothermal energy to satisfy the demands for electric power, heating and cooling. Energy piles – foundation piles laced with tubing to extract geothermal energy – will provide an innovative source of renewable energy achieved by combining the latest piling and geothermal technologies.

4. Renewable off-site energy supply, including low-impact hydropower, wind power and solar power. Energy will be generated from renewable natural resources, such as sunlight, wind, rain and tides – sources that need not cost anything to the planet, and will be distributed through national and local grids to end users. From the wind turbine on top of Boston City Hall to the 500 kW solar farm we built on a former landfill in Lancaster (with another proposed on a closed airport site in that town), unused land and untapped resources will power the cities of the future.

5. Waste recycling. Waste products will be recovered and put to use. This concept goes beyond the daily household and office refuse to include dismantled buildings and construction waste. Our renovation of the Harvard Art Museums has achieved an exceptional 98 percent recycling rate.

6. Green roofs. Roofing systems will use vegetation to absorb rainwater and reduce heat reflection. Vegetated roofs can help regulate building temperatures to reduce energy use. They also create a permeable surface for storm water on a traditionally impervious space. One local example of this is the new Harvard Law School building in Cambridge; the green roof insulates the building and absorbs water to prevent runoff during rainstorms. That rain is collected and used later to irrigate plants.

7. Rainwater harvesting. Rainwater will be collected, stored and used for irrigation – perhaps even for livestock drinking water. While the latter may not be needed in urban areas, rainwater collection is becoming increasing prevalent in suburban construction projects, too, such as the Bancroft Elementary School in Andover, expected to be complete next year.

8. Water recycling. Wastewater will be partially treated and reused, for example, in buildings for flushing toilets, or for agricultural and landscape irrigation. EF Education First is doing this with their North American headquarters building under construction in Cambridge.

9. Regional materials and resources. Buildings will be constructed with locally sourced materials, preferably with recycled content and produced with minimal effect on the environment. These should last the entire lifecycle of the building and be easily recyclable afterwards.

10. Locally processed materials. To contribute zero waste, locally-sourced materials will be produced to consistent quality standards and tagged for inventory control and just-in-time delivery to the construction site. Another approach is using more recycled materials in a renovations or new construction projects, which was the case at the state’s new data center in Springfield, at the site of the former technical high school. The building, which is 50 percent more energy efficient than a typical data center, was constructed using 26 percent recycled content.

11. Healthy indoor air quality. No harmful compounds will be allowed in, including particulates, combustion gases, outdoor pollution, mold, microbial contaminants and compounds released by materials.

12. Old buildings made energy efficient. Through renovation and by using updated green technology, old buildings will be retrofitted to reduce their impacts on the environment.

Every day, improvements are being made to our cities to make them more energy efficient, less wasteful and healthier for all inhabitants. As these twelve points illustrate, the completely green city will take a multifaceted effort on behalf of the government, consumers, builders and designers. It’s a lot to take in, but with some careful consideration and thoughtful preparation, the reward will be so much greater than the work.

12 Reasons Why ProjectDox ePlan System is Your First Solution

Electronic Plan Submission, Review and Tracking is a critical component to streamline government operations and help citizens and their government to work together. ProjectDox excels at managing all kinds of project information. It gives you the flexibility to centralize resources and coordinate people/departments with low-to-no ramp time

1. Stand-alone Solution: ProjectDox is a total, stand-alone solution. Although ProjectDox often integrates with other core solutions, it offers complete plan review tools and processes within its own work flow engine: automatic file uploading, editing, tracking, reporting, and automatic routing as core functionality. No other back office software needs to be installed in order to benefit from ProjectDox. Other solutions are more or less tacked on and tied into their back office permitting/planning solutions that must be implemented before their eplan system can be implemented. These solutions can take years to implement. With ProjectDox you can reasonably implement a full system within six months.

2. Open File Format: ProjectDox handles over 250 file types. Other ePlan solutions handle one file type, typically pdf. ProjectDox works with pdf and hundreds of other file formats. If your agency is interested in an agency-wide solution, then multiple file types are essential to an efficient solution.

3.Proven Large Customer ePlan Solution: ProjectDox has over 100 customers, as much as five times the customer base as other solutions. ProjectDox has proven success in cities with populations of over 500,000.

4. Cross-departmental Solution: ProjectDox provides work flow to integrate with departments across the enterprise. Other solutions may work with only one department, say, in building but not with Engineering. ProjectDox has customers in every department across an agency. Planning may uses pdf. files and Engineering may use CAD files. Further, GIS uses ESRI. This is not an obstacle for ProjectDox.

5. Workflow Integration: Behind the scenes ProjectDox provides a workflow engine that integrates with your back office software. Some solutions are just a viewer with some markup tools. ProjectDox provides a full set of edit and markup tools along with a workflow engine that automatically routes plans and projects based on a number of events, roles, and responsibilities.

6. Safe and Secure: Eleven levels of security protect your processes with 256 bit encryption. As soon as files are uploading into ProjectDox, the system locks down the original files and protects them. ProjectDox secures the intellectual property of architects and engineers. With its own proprietary software, ProjectDox then re-publishes the files in as many copies as necessary to conduct simultaneous or linear review. These processes are user-defined. All edits, markups, comments, and notes are tracked and time-stamped so the project coordinator can manage the entire process without losing a file.

7. No Cost for Your Customers: ProjectDox is offered as an enterprise license. There is one cost for an unlimited number of users agency wide. As your use of ProjectDox increases, and more and more users are added, no additional license fees are required. Further, your customers who upload their files are not required to purchase any additional licenses or software. Some pdf –based solutions will require that everyone purchase Adobe software. That software can be expensive and must be version-current. This is cumbersome and non-business friendly. ProjectDox removes this obstacle.

8. No Additional Cost for Outsourcing: Some agencies outsource their plan reviews. There is no additional cost to third-party reviewers. Agencies simply invite the third party reviewer into the system and all the edit tools and processes are available. Access is granted by the agency and controlled through typical rights and permissions.

9. No Manual File Conversion: If the planning department uses pdf files and then needs to share that with the engineering department that needs a CAD file, ProjectDox can automatically handle the CAD file. Other solutions will require that the project coordinator manually convert this file.

10. Discrete Reviews: ProjectDox returns only the plan pages that need to be corrected. Other eplan solutions copy and return the entire set of plans regardless if all the pages need correction or not. This cumbersome activity can clog your network as the volume increases.

11. Versioning: ProjectDox tracks all projects and pages and then versions them. No additional files are allowed to be uploaded. Any corrections or additions are highlighted in RED and GREEN. With the side-by-side and/or overlay-differences tools, reviewers can quickly spot any changes. All corrections or changes are quickly captured with text and images and copied to a Word document. This document can be emailed automatically to the customer.

12. GIS Integration: Built within ProjectDox is a GIS viewer. With one click, you can bring up the building plans and reviews for a specific address.
