Justin Aruck

Partner | Building Performance

While a student at James Madison University, Justin saw a presentation on energy auditing through the college’s student chapter of the Association of Energy Engineers and was immediately hooked. He loved the opportunities for creativity and the ability to affect real changes with real impacts. He can now say he has had the privilege of working in sustainability and energy efficiency for over 12 years.

His favorite way to describe what SBP does to friends and family is to say “Well, before a building project happens, we work to figure out how a project that does not exist might exist if it existed, and use that work to find meaningful information that helps the building exist better when it finally does exist. Once the project is underway, we work to make sure the project comes to exist in the way it was intended to exist.”

Outside of the office, Justin can be found existing and working on various renovation projects in his historic (and slowly getting more energy efficient) home on Chincoteague Island, as well as acting and designing/constructing sets and lighting for The Chincoteague Island Theatre Company, which was founded by his (beautiful and talented) wife in 2011.

Scott Neill

Specialist | Sustainable Programs

Scott’s passion for the environment came about from camping and canoe trips in Ontario and Maine. His inspiration – and some degree of romanticism – came from environmental writers like Thoreau, Jon Krakauer, and Edward Abbey. After receiving an undergrad in cultural anthropology from UMW, his ambitions grew out of the unique understanding whereby Westerners view nature – as an object of alienation. Seeking to close this gap that he too was experiencing, he spent several months in South America learning amongst Amerindian societies. 

With the fortune to have had this experience, Scott went back to earn a master’s in natural resources at Virginia Tech to apply theory into practice. As a student consultant he developed a practical understanding of resource challenges we are currently facing. Energy being the primary global driver that dictates environmental policy. Ever since he has worked in various capacities installing retrofits, performing residential ratings, and energy modeling. SBP has encouraged him to pursue a balanced approach to energy consulting; reaffirming an ethos that people with informed decisions (or lack thereof sometimes) are what makes the world tick. Realizing them as the most important of resources will pay off for future generations and our planet.

Aside from being a national parks junkie, Scott enjoys hiking with his wife Sarah, reading, occasional DC United games, spicy foods, jiu jitsu practice, and volunteering.

Rachel Nicely

Partner | Sustainable Programs

As a youngster, Rachel was fascinated to learn about green house gas and pollution. Over the years, she has turned this fascination into her chief ambition to single-handedly save the earth. She currently spends her days advising projects how to incorporate sustainability into the built environment.  Originally an army brat, she decided to stay in the DC area so she can pollute the air while in traffic, thus keeping herself marketable.

Rachel joined SBP in 2011, adding to the 70% JMU ISAT population within the company – Go Dukes! Though she has a master’s degree in Environmental Engineering, she has yet to design a wastewater treatment system and hopes that will never be in the cards for her (crappy work). Rachel’s 9 years of experience with LEED projects has led her to managing the LEEDers in SBP where the team kicks sustainability butt.

Her family has been susceptible to her environmental influences while updating their 50+ year old home.  They tolerate her antics only because if she ran away they would never have clean clothes. She and her husband are raising two rug rats raring to save the planet.

Jake Torok

Partner | Building Performance

After spending no less then half of his parenting-life reading (and re-reading) Dr. Seuss, it’s only fitting that Dr. Seuss has provided Jake with some much needed guidance when it comes to maintaining a clear head both at home and work.  When not being fully consumed in the energy modeling lifestyle at SBP, Jake balances life with two little ones, a hyperactive dog, and his patient wife. Somewhere in-between he finds time to coach swimming, train for marathons, fix-up his dream home, and play countless games of Pretty, Pretty Princess. Jake’s affinity for problem solving helps to work through the trials and tribulations of potty training a toddler, but ultimately piqued his interest in building energy performance and drove him into the field of energy modeling.
