Published: April, 20 2018

Former military service members, including our own Gavin Maxwell, discuss how the UA Veterans in Piping Program provided a smooth transition from military service to a successful civilian career. The United Association established the Veterans in Piping (VIP) Program to equip military service members preparing to leave the service with sought after skills that lead to lifelong civilian careers in the increasingly in-demand pipe trades. The program teaches 18-week accelerated courses in Welding, HVACR and Sprinkler Fitting at military bases across the United States.

Is Your Building Helping or Hurting the Environment?

Published: February, 4 2016

ENERGY STAR® was created more than 20 years ago as a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. Since then, it has become a respected symbol of smart, ecological manufacturing, building, and design.

A high ENERGY STAR® rating goes hand-in-hand with lower utility consumption, more efficient technical systems and a more positive impact on the environment. 

An estimated $12 billion in societal benefits can be traced back to the program by reducing damage caused by climate change, just in 2014 alone. According to the latest Energy Star annual report, greenhouse gas emissions have been reduced by an incredible 2.5 billion metric tons since the start of the program in 1992.

To put that in perspective, if you were able to gather every single human being on the planet and stand them all on a giant scale, they would weigh about 367 million metric tons. So the amount of greenhouse gasses eliminated through the ENERGY STAR® program is nearly 7 times the weight of the entire human population.

The savings are not limited to emissions either. There’s a very real economic benefit to the success of the ENERGY STAR® program.

Since 1992, individuals and businesses have saved an estimated $360 billion on utility bills by following ENERGY STAR® guidelines and using certified equipment and buildings. In 2014 alone, the figure was $34 billion.

How does your facility fit in?

As part of the Service Logic family of companies, Tolin Mechanical is proud to be one of the nation’s leading ENERGY STAR® partners with one of the largest portfolios of rated commercial buildings in the United States.

But it’s not about being the biggest or the best – although we’ll continue striving for that too. It’s about the kind of results noted above. It’s a matter of pride that we have the privilege of helping our clients save money and improve the environment simply by doing what we do best.

We live in the same areas where we work, so reducing emissions and saving energy is just as much a personal effort as it is a professional one. Looking back at the incredible results ENERGY STAR® has achieved in the last 20 years, we’re proud to play a role for buildings throughout the Southwest and Washington D.C.

Wildwood CasinoPlay Wild. Live the Action.

Published: April, 2 2015

Tolin identified flaws in the air-handling system control sequence that resulted in large swings in supply air temperature and overheating as the system overcompensated for deviations in temperature set points.

This project is expected to feed over $1.5 Million back into Wildwood Casino budgets that can be used for future equipment replacements, additional energy projects, or other facility improvements.


  • $80 million construction
  • 58,000 square feet
  • 500+ gaming machines
  • 2 restaurants, 1 bar and a coffee shop


  • $74,300 first-year utility savings
  • 9-month payback
  • 38% reduction in natural gas consumption


The management of Wildwood Casino, a modern Las Vegas-style gaming facility in Cripple Creek, Colorado, had some elusive thermal comfort problems. These problems were causing visitor complaints, leading to a decline in guest satisfaction. Of course, the guest experience is of paramount importance for Wildwood Casino in order to build their brand and to encourage guests to return; thermal comfort is a major component of this experience. In addition to the guest comfort issues, the casino was aware of the need to put a planned maintenance program in place to protect their investment in the building’s mechanical system by increasing the life of the equipment through preventative maintenance. Wildwood management was also hopeful there were ways to reduce the high utility costs that are characteristic of casinos in Colorado’s Rocky Mountains.


In order to address these issues, Wildwood Casino turned to Tolin Mechanical for assistance. Tolin immediately began a concerted diagnostic effort to understand the building systems and target the root cause of the comfort problems. All efforts were focused on identifying a customized solution through remote and on-site monitoring, trending, mechanical code review, and a detailed analysis of comfort complaint patterns. After investigating the system operation over the first few months of the agreement, Tolin identified flaws in the air-handling system control sequence that resulted in large swings in supply air temperature and overheating as the system overcompensated for deviations in temperature set points. Disproportionate design ventilation rates contributed to the problems that resulted in the improper and inefficient operation of an otherwise modern HVAC system.

Armed with data and system-specific knowledge, the Tolin team refined a corrective scope to not only make major improvements in occupant comfort, but also greatly reduce utility consumption. An energy model was created in parallel with scope development and early financial analysis indicated an exceptionally high return on investment. Soon after approval from Wildwood management, the Tolin team implemented air-side mechanical and control modifications to tune the system for more even temperature control and provide demand-based ventilation based on real-time occupancy. Project performance was tracked for one year with a weather-adjusted utility analysis and ongoing control monitoring.

After one year of performance, the utility data has proven an unprecedented 38% reduction in natural gas consumption at the meter in addition to the estimated electric savings. In total, Wildwood Casino saved $74,300 in utilities in the first year after implementation, which recovered the project cost in less than 9 months. Over the 15 years of estimated remaining service life for the HVAC system, this project is expected to feed over $1.5 Million back into Wildwood Casino budgets that can be used for future equipment replacements, additional energy projects, or other facility improvements. Wildwood has logged the fewest comfort complaints on record which have contributed to a discernible growth in market share during the performance period.


Wildwood Casino is located in historic Cripple Creek, Colorado where a century ago, those seeking wealth and fortune set out to strike it rich by mining for gold. Today the community is rich in history and character with Wildwood Casino giving the old-fashioned streets of this quaint mining town a modern touch, while still holding true to what brought folks here 100 years ago - wealth and fortune.
