Green Building December 12th Luncheon: Unstoppable: The Transition to Renewable Energy

Today, building owners and designers are looking to minimize the energy and carbon footprint of new and existing buildings. LEED V4 and the Architecture 2030 Challenge are pushing the industry beyond energy efficiency features into on-site renewable energy generation. Join Taylor Brown and Devin Welch from Sun Tribe Solar, a Charlottesville-based solar energy company, as they discuss renewable trends and design best practices. Come learn more about solar photovoltaics, battery storage options, and Power Purchase Agreements (PPAs) from leaders in the field.

Taylor Brown co-founded Sun Tribe Solar to increase solar PV’s market share on the east coast and is now operating as the Technical Director. Before launching Sun Tribe, Brown worked for Siemens Energy North America. For the first five years with Siemens, Brown was a field project manager performing modernizations and upgrades on steam turbine generators ranging from 150 MW to 920 MW throughout the United States. Brown holds a B.S. in Mechanical Engineering from Virginia Tech.

Devin Welch, co-founder, is also responsible for market strategy at Sun Tribe Solar. Passionate about sustainability, Welch has spent his career championing free market principles as a means to achieve positive change across a broad range of environmental issues, with a focus on finding and capitalizing upon the critical intersections of sustainable best practices and corporate self-interest. At Sun Tribe, Welch continues his work on market transformation by engaging with individuals, businesses, and governments to reimagine the way energy is produced while realizing tangible benefits for all stakeholders. As a member of the leadership team, he has helped Sun Tribe to become one of the fastest growing solar companies in Virginia. Welch is a published author and holds a B.S. in Management from Virginia Tech.

The Cloud Shower: Disruptive Shower Technology?

There are two types of technology change: Incremental and Disruptive. As a designer, disruptive is way more fun.

Incremental: How do we get more with less? For showers, building codes limit their consumption to 2.5 gallons per minute (gpm) while green building rating systems are pushing manufacturers to get more with less; down to 1.5 gpm. The problem is that at a certain point there is a physical limit to the incremental change and efficiency gains will level off. My gut says that for shower heads this point is somewhere around 1.2 gpm. Any 50% reduction is something to be proud of, but it has taken a long time.

Disruptive: What if we ask a different question altogether: “Is there a better way to take a shower?” A couple startups are trying to answer this question with what they call a cloud shower. Previously only available as a luxury shower add-on, the technology is similar to a type of commercial humidifier. They claim that their technology not only uses 75% less water, but also provides a much more luxurious showering experience: providing more even coverage and rinsing more effectively. We now have a sudden 75% drop in water consumption, which also results in a major drop in the amount of water that needs to be heated, which in turn saves a lot of money. All this by simply swapping out a shower head! Brilliant!

Green Building February Lunch: Nearby Tales of Net-Zero Schools

We hear a lot about industry leading net-zero energy and net-zero water schools happening in progressive communities around the globe, but we don’t hear as much about what’s happening with green schools here in the Mid-Atlantic. Local professionals will provide an update on net-zero energy and net-zero water schools in Virginia and Maryland. The interactive presentation will include a discussion of regional green school efforts and what challenges, and opportunities, lie ahead in the future.

This luncheon will be held at City Space, 100 5th St. NE, on the Downtown Mall, Charlottesville, VA. Doors open at 11:45 and the Seminar begins at 12:00. Luncheons are open to the public. Lunch is provided, attendance is free for GVGBC members and $10 for non members. Register Here

LEAP Home Energy Checkup

If you’ve been thinking about making your home more energy efficient but don’t know where to start, the Home Energy Checkup from LEAP is a really good and inexpensive way to have a professional check out your home and give you great advice. We just did our house and I had a lot of fun. Our coach was a wealth of knowledge and really friendly; he even insulated some of the pipes in our house free of charge. Overall it was a great experience and helped prioritize projects that will have the greatest effect for the least amount of money. Highly recommended.

Site Solar Shading Survey App How-to Guide

The first thing you need to do before building any sort of solar-powered project is to figure out how much sun the site receives. Trees, mountains and houses can all block solar energy from reaching whatever you have collecting it. In the olden days you would go out to the site armed with a compass, protractor, cardboard, string and a washer and plot out the obstructions on paper. Now we have some slick apps for android phones and tablets to help us. Here’s a guide for making a Solar Site Survey Chart using apps for android with a little post processing on a computer.

1. Use the Solar Shading app to make a new project and trace the solid horizon. Follow the directions for the app; there is no need to repeat them here.  Make sure that the program knows your position or things will be thrown off. It is important to trace just the mountains and other solid things that aren’t going anywhere because you certainly can’t change those. Use the share icon in the app to export the pdf of the report; it is useful as it is, but we’ll do more with it later.

2. Use the Solar Shading app to make another new project and trace the “green” horizon. This time, trace the outer edge of all the trees and any other objects that aren’t completely solid. Use the share icon in the app to export the pdf of the report; again, it is useful as it is, but we’ll do more with it later.

3. Download all of the reports from your phone to a computer.

4. Download a clean solar chart online for the survey location from http://solardat.uoregon.edu/SunChartProgram.html

5. Use Photoshop, GIMP, or another image editor that allows the use of layers to superimpose and line up the solar chart made in step 4 over the chart that the app made in step 1. On a new layer use the paintbrush and masks to make a clean horizon on the chart. Hide the chart from step 1.

6. Now bring the solar chart that the app made in step 2 under the chart built-in step 6 just like you did in step 5. On a new layer use the paintbrush and masks to make a clean “green” horizon on the chart. Hide the chart from step 2. Put some text to let everyone know where in the world the survey was taken and you’re done.

7. Doing the survey with the less expensive augmented reality apps SunPlan and Sun Surveyor is a similar process, but is more labor intensive. Use the app to take augmented reality screenshots to create a panorama on a computer later. I like to turn on the winter and summer solstice sun paths in the app because it gives a nice reference point when using them later. It’s a good idea to take a panorama even if you used the Solar Shading app to make the solar chart because it shows what the obstructions are. They are the most valuable together.

8. Turn the images into a panorama using a panorama maker program like Microsoft ICE. The augmented reality pieces confuse these programs pretty badly, so it’s not going to be flawless. Let me know if you find a way to get a cleaner panorama!

9. Download a clean solar chart online for the survey location from http://solardat.uoregon.edu/SunChartProgram.html

10. Open Photoshop, GIMP, or another image editor that allows the use of layers to open the chart made in step 9 side by side to the panorama made in step 8. On a new layer use the paintbrush and masks to make a clean horizon on the chart from step 9 using the panorama as a reference. On a new layer use the paintbrush and masks to make a clean “green” horizon on the same chart using the panorama as a reference. Put some text to let everyone know where in the world the survey was taken and you’re done.
