So over the next couple of slides, we're going to talk about rating systems. Okay? And these rating systems are for projects. And this slide was developed to show the progression of some of the sustainable assessment tools that are out there. LEED was one of the first it started back in 1994 and is by far the most successful. It rates buildings, and you've had throughout the years other rating systems that have been developed and released into the industry. And probably the most recent has, was Invest, which is developed by the Federal Highway Administration and Envision, which was developed by the Institute of Sustainable Infrastructure. And at Skanska, we worked with Columbia University and Professor O'day on looking at all these different systems and doing a comparison in terms of what the system provided, who was using it and what type of projects were being certified under these rating tools. So thank you for those Columbia students that did that work, and it's been very valuable to us. So today I am going to speak about these four, it will be LEED, Greenroads, Invest, and Envision. Okay, so lets first talk about LEED, which stands for lead, leadership in energy and environmental design. It is by far the most successful rating system out there and as such there are plenty of resources to study the pros and cons of the system,mostly pros. It's transformed the building industry. A few people on the construction side have not heard of it. And they are constantly, constantly looking for ways to advance the system and make it more stringent, and tighten the belt on performance of a building. It was instituted in 2000. And it is developed by the US Green Building Council. They have over 32,000 certified projects, which is pretty amazing. And it applies to planning, design, and construction of a building. And how works is you have a score card with a list of credits, and those credits are broken out into citing, where you would cite the project, the materials that you would use, your water consumption and you energy consumption, how that project is connected into the communities. Greenroads was developed By the University of Washington and CH2M Hill, it was instituted in 2009. They have approximately 81 projects across the U.S, and it applies to roadway planning, design, and construction. It is again a very useful tool but it is somewhat limited in that it's geared towards transportation projects only. INVEST stands for Infrastructure Voluntary Evaluation Sustainability Tool. It was developed by the Federal Highway Administration and it was instituted in 2012. So it's relatively young in terms of rating systems. It is a voluntary system, so there's no third party verification or an award. It's just something that you as a owner or a developer could rate your own project. They have 66 projects across the US. It applies to the planning, design, construction, and operations of roadways. And again it's a self assessment tool. And lastly we're going to talk about Envision Sustainable Infrastructure Rating System. This was launched in 2012. And it was developed and governed by the Institute for Sustainable Infrastructure in conjunction with Zofnass Program at Harvard University. They currently have 12 verified projects in North America and they estimate that since it's a free planning tool available online, they believe that there are close to 800 projects across the US who are using it. Even though they may not be going through with the verification. They may just be using it to plan their projects or plan their master plan for a city or a campus. Where are the Envision projects? Well we see they are mostly concentrated on the the West Coast in the North East and Texas and Florida. These are the geographical areas that also score well with Greenroads and Invest and LEED. So, it's not surprising that these states would adapt such a system. These also happen to be the areas where the legislation has passed for design, build, and P3 work. So in the parts of the country where The delivery, project delivery method is changing from the bid build to a design build or P3, you're seeing those. That's where the concentration of sustainable rated projects are occurring. So let's take a deeper dive into Envision. And to do that, I am going to quickly Go on to their webpage, so this is the Institute for Sustainable Infrastructure's webpage. You'll see here I've logged in as myself. And there is a a guidance manual that is free of charge that you can download. And that is essentially a document that is full of best practices in the industry. So you can use that just as purely reference on your project and you could design your activities using those best practices in mind. There is a checklist. A checklist is a very preliminary review of a project and it allows project teams to run through all the credits that would be in the guidance manual, but only ask yes or no based on the credit. And by doing that, it gives you an idea of where the project is going to score, and where the strong points and where the weak points are. And you can You can adjust your attention accordingly. Another part of the website is this Envision score sheet. So if you've gone through the checklist and you said, okay we've identified where we can make improvements we've made this improvements now we want to go through and actually rate the project. Well you can do that using this online Envision score sheet. And one thing I'd like to do is if you come up here to the learning center tab, we can go down and click on presentations, and I will run through the presentation on the Envision rating system for you. So Envision, Envision, you'll notice the two logos on the bottom, the Institute for Sustainable Infrastructure and the Zofnass Program. Essentially the Institute for Sustainable Infrastructure was created by The American Society of Civil Engineers, The American Public Works Association, The American Council for Engineering Companies. Those three entities created the Institute for Sustainable Infrastructure. They came up with the very early edition of Envision. And at the time they were reviewing it in 2011, they realized that the Zofnass Program at Harvard University had done the same. So they partnered in order to develop one comprehensive and robust system. And that is what is called Envision today. So I mentioned a few other rating systems and that they were particular to the different types of structures. Envision is very holistic you can apply it to many different types of infrastructure. You can apply it to energy, water, waste, transport, landscape and now information. So, you've got the information technology industry. So all these things can go through an Envision rating system. They can also use the system to plan and design the project. What's nice about Envision is not only does it cover a bridge, to a tunnel, to a waste water treatment plant, to a local park, but it's scale able so you can have few million dollar project up to a few billion dollar project. You could scale the system up or down however you see fit. So the Envision rating system looks at 5 categories. It looks at quality of life, it looks at leadership, resource allocation, natural world, and climate and risk. Quality of life has to do with the purpose of the project, are you building the right project? It looks at the community and it looks at well being. Is that project going to increase community productivity? Is it going to increase or improve quality of life? You'll notice a lot of these same themes are things that we talked about earlier in the presentation. Leadership talks about collaboration. Collaboration between the team and the owner, collaboration between the teem, the owner, the community, any stakeholders, end users. It also goes on to talk about management, how is the project set up to promote a sustainable approach. It talks about planning. Do you have the proper plans and procedures in place? That again, address all of those issues that we talked about before. Resource allocation, this gets into your quote unquote green aspects of a project. It talks about your resource, your materials, recycled content. Where are they coming from? Talks about energy usage, water usage, waste, waste diversion from landfills, that's all locked up in resource allocation. Natural world deals with siting, and land and water, and biodiversity. So where you putting the project? Are you putting it on a brown field that needs to be cleaned up anyway? Are you putting it on a green field that has a protected species on it. So it rates projects based on where the project is located and also, it also rates the project if, say, for a 20 mile highway, obviously there could be different types of ecosystems along the way. So how is it preserving all those different ecosystems. And lastly climate and risk. And I mentioned this briefly in the very beginning of the lecture, the concept of resilience and durability. And this is one of the categories within Envision. It talks about lowering greenhouse gasses. So therefore to mitigate any climate change impacts. But also resilience during a natural disaster, or some other event that has been brought on by climate change. Are we making, are we building things that are putting us at risk or putting future generations at risk? Or are we building assets within the United States that are going to be durable and resilient and last for decades in to the future without high maintenance costs and vulnerability? Is there redundancy built in to the system? If a bridge pier is, god forbid compromised for whatever reason, is there an alternate route or an alternate way around that that the society has in case of an emergency
