October is National Energy Awareness Month so we wanted to take a look at where Public Works operations could improve their energy efficiency.  When managers think about energy savings, heating and cooling buildings and fuel for motor vehicle fleets typically comes to mind since just almost all communities have those responsibilities.  However another common but often overlooked responsibility where energy savings can be found is in the construction and maintenance of roadways.  Quite a bit of energy goes into building roads and even more is invested in the maintenance of the pavement and adjacent right of way.  The design of roadways and intersections also affects how much fuel is used getting from point A to point B.  The effort and frequency of maintenance dictates how much energy is invested in the long run.  In order to explore potential energy savings associated with roadways those interested can visit the Greenroads website.  The Greenroads Rating System is a sustainability rating system for roadway design and construction projects.  Greenroads was established in 2010 and is a very similar process to the LEED certification program for building projects.  There one can find a variety of ways for roadways to be more energy efficient including:

  • Maximizing the reuse of onsite materials and use of recycled materials
  • Optimizing equipment types and sizes to reduce fuel costs during construction
  • Using energy efficient asphalt mixes
  • Minimizing transportation distances for new materials and disposal of materials
  • Minimizing detours and additional travel distances during construction
  • Optimizing routes for efficiency and consider round a bouts and other techniques to reduce signals and vehicle idling http://sustainabilitytoolkit.apwa.net/
  • Designing pavements, bridges, other major structures, and landscaping to minimize maintenance costs and maximize service life and associated energy use.
  • Considering the use of  energy efficient lighting and signals
  • Providing for mass transit and multi modal forms of transportation which is also a part of Complete Streets
  • Supporting and Encouraging pedestrian and bicycle use

These techniques can be applied to both large and small scale projects.  In Fayetteville NC, the City is using these techniques as part of the Person Street corridor facelift.   This “Green Street” project, located within the heart of Downtown Fayetteville, represents how existing gray to green conversions in major downtown transportation corridors can be completed using innovative and energy efficient “Green” techniques.  The Public Works Department in Raleigh NC is using the Sandy Forks Road widening/improvement project as a pilot project to provide staff with additional knowledge and familiarity with the latest sustainable transportation design best practices that would benefit the City’s approach to future roadway projects.  This project includes the first public roadway median bioretention area to be installed by Raleigh and addresses energy conservation through the use of native landscaping; Bike & pedestrian access; context‐sensitive solutions, and the use of warm mix asphalt/recycled asphalt.

To celebrate in style, I thought it would be worth highlighting that the American Council for an Energy Efficient Economy (ACEEE) has put out their 10th edition of the State Energy Efficiency Scorecard: http://aceee.org/state-policy/scorecard. For the 6th year in a row, my home state of Massachusetts is #1! Which is always something I am happy to share, though this year we are sharing top billing with California.

 

The objective of the Scorecard is to rank states on their energy efficiency efforts and ultimately encourage them to keep pushing towards being #1. We have seen that improved efficiency promotes economic growth and improves environmental quality. The report examines policies, programs, best practices, and overall leadership in six policy areas:

  • Utility and public benefits programs and policies
  • Transportation policies
  • Building energy codes and compliance
  • Combined heat and power (CHP) policies
  • State government–led initiatives around energy efficiency
  • Appliance and equipment standards

Additionally, this year ACEEE gave credit to those states that have PACE enabling legislation “to recognize innovative state efforts to leverage private capital toward efficiency goals.” PACE stands for Property Assessed Clean Energy and it is a financing mechanism that is growing in popularity as it allows energy efficiency, clean energy, and resilience improvements to a property to be financed through property taxes. A lien is placed on the property until paid in full, but this addresses concerns that short-term owners have had with efficiency and other improvements that might have a longer payback period than the amount of time they are interested in staying in the building. You can find out more at http://pacenation.us/.

 

So how does Massachusetts do it??

 

To be #1 for six years in a row is something. What does Massachusetts have or do that is so special? Well, according to ACEEE, “Massachusetts has one of the most ambitious energy efficiency resource standards in the country” - that means we have established specific, long term targets for reducing energy use that the utilities in the state must meet. The Commonwealth also passed the Green Communities Act back in 2008, which identified energy efficiency as a first priority resource throughout the state and set up a number of programs to support that, including the Green Communities program which drives energy efficiency at the local level. For more information: http://www.mass.gov/eea/energy-utilities-clean-tech/green-communities/.

 

While these are great achievements, Massachusetts needs to keep driving forward to maintain its claim to the top spot. California will keep us on our toes. There were three categories where California scored higher than Massachusetts: Transportation, State Government Initiatives, and Appliance Efficiency Standards.

 

On the Transportation side, Massachusetts needs to actually achieve significant reductions in vehicle miles travelled per capita. We have not been able to demonstrate that yet. Under State Government Initiatives, the missing point is for a statewide building benchmarking and transparency requirement. This is a fairly innovative policy at the state level. Local governments have been leading in this area for several years now (http://www.buildingrating.org/graphic/us-benchmarking-policy-landscape). It will be interesting to see if/how various states step up to take this on. Clearly California already has, but so have a few others to varying extents - Washington, D.C., Alaska, New York, and Kansas, to name a few. The Institute for Market Transformation has created a great map (below) highlighting the state and local benchmarking policies across the country.

 

Finally, under appliance standards, well California set the bar here and while Massachusetts had previously had appliance standards, we are now just working with the federal standards.

 

How can your state improve its ranking on the scorecard?

 

Like Massachusetts, California and other states in the top ten are there because they have moved well past the voluntary programs and into strong legislative action that establishes standards for efficiency that must be met and those standards are tightened on a regular basis. I have worked with lots of local governments in many other states and that is the differentiating factor in successfully moving towards a more sustainable community. We have to stop being scared to REQUIRE these changes. Massachusetts, California, and others are proving that you can enforce strict efficiency standards and actually spur growth- not stifle it. This is a great lesson for those that feel beholden to developers and others that are constantly fighting these necessary changes.So while you are prepping for Halloween, remember that while jack-o-lanterns can be fun for Halloween, they are not really practical and therefore not your best strategy to become more energy efficient.

 

Whether considering state level legislation action or not, ACEEE suggests these strategies improve your statewide energy efficiency efforts:

  • Establish and adequately fund an EERS or similar energy savings target.
  • Adopt updated, more stringent building energy codes, improve code compliance, and involve efficiency program administrators in code support.
  • Set quantitative targets for reducing VMT, and integrate land use and transportation planning.
  • Treat cost-effective and efficient CHP as an energy efficiency resource equivalent to other forms of energy efficiency.
  • Expand state-led efforts—and make them visible.
  • Explore and promote innovative financing mechanisms to leverage private capital and lower upfront costs of energy efficiency measures.

GOOD LUCK!

C4S hosted its first Twitter Town Hall July 25, 2016 to engage APWA members about the challenges they face related to sustainability in public works.

 

The Twitter Town Hall was a great way to leverage the personal expertise and experience of the C4S Leadership Group in order to support public works professionals who need to know how to integrate sustainable principles and practices into their day-to-day work.

 

C4S Leaders Kim Lundgren, JC Alonzo, Steph Larocque, Jen Winter, Matt Rodrigues, Dwayne Kalynchuk and Michael Simpson participated. The conversation has been archived below.

APWA just wrapped its annual conference — recently rebranded as PWX (Public Works Expo) — with all the cool and technologically advanced components you would see at a tech conference. As someone who has frequented Dreamforce (Salesforce.com’s annual conference), which is the ultimate in conference innovation, I was certainly impressed with the steps that APWA has taken to advance this conference. What I found even more impressive, however, were the very visible signs of how this conference was clearly also the most sustainable one that APWA has hosted.

 

From using an interactive app instead of a printed program to an entire session track on sustainability, APWA has certainly stepped up their sustainability game. The APWA Center for Sustainability (C4S) also used PWX to launch its new online Sustainability Toolkit. This new platform makes it incredibly easy for Public Works professionals to sort through the hundreds of resources C4S has collected over the years and find specifically what they are looking for. In May for Public Works Week we wrote about how the Public Works sector is involved in sustainability and carbon emissions reductions through things like biking.

Of course, selecting a sustainably advanced city like Minneapolis to host the event does make it easy to see sustainability in action everywhere you turn. From the walk between the hotel and the convention center and walking from session to session in the convention center it was hard not to spot great examples of sustainability.

Every single receptacle in the Convention Center had options for Recycling and Composting, along with trash. That is rare in most cities and at most conferences I attend. Even on local construction sites, the City made sure to keep both trash and recycling bins available.

Some of Minneapolis’ key sustainability features I saw in action:

  • Bike Share Program, bike lanes
  • Water bottle filling stations
  • Recycled, renewable artwork
  • Green Infrastructure integrated throughout City
  • Sustainability signs on construction sites

Next year PWX moves to Florida, and we’ll be there to see host city Orlando’s sustainability initiatives on display.
