Wiegmann Associates Completes GameWorks Denver HVAC Project

Gameworks BldgSt. Charles-based Wiegmann Associates has completed a design-assist HVAC project for the new GameWorks Denver, a family entertainment center. Wiegmann’s HVAC solution reduced equipment and installation costs, and will result in annual energy savings. The general contractor was Catamount Constructors, Inc.

The primary project challenge was to adapt the building’s existing HVAC equipment, designed for an electronics store, to serve the needs of a 33,800-square-foot multi-purpose facility including a restaurant and bar, arcade room, Laser Tag arena, eSports center, and small and large private event rooms.

Wiegmann performed heating and cooling load calculations, which allowed for a 25 percent reduction in equipment capacity. They installed 10 new rooftop units instead of refurbishing older equipment, simplified the ductwork and air distribution system, and replaced several ductless split systems with more economical solutions, all while reducing mechanical construction costs by 28% over the original design.

Wiegmann also programmed the building’s HVAC controls for an estimated 12 percent reduction in annual energy costs.

Wiegmann Associates is a St. Louis-based mechanical contractor serving the commercial, industrial and institutional markets, and a national leader in design/build HVAC projects.

Ensuring Generator Longevity

Light loading responsibly

While it’s not advisable to run generators below their optimal workload-to-fuel- consumption level, the reality on job sites and in emergency situations sometimes demands it. If this happens to be the case, regularly scheduled and preventative maintenance regimens become even more crucial for maintaining the health of the power system. Generators regularly expected to run on light loads should be subject to more rigorous maintenance regimens to ensure there’s no excessive wear or deposit buildup.

If generators must be run at light load for a period of time, then in general they should afterwards be run under an increased load. This raises the temperature and pressure within the generator’s cylinders, which helps to clean off deposits in the combustion chamber.

Light loading should be even more limited for natural gas generator sets. It’s recommended that they be run at a 0 to 30 percent load level only for half and hour, and from 31 to 50 percent load level for only two hours. All light loading should be followed by at least two hours of running at no less than a 70 percent load level.

Scheduled and preventative maintenance

Scheduled and preventative generator maintenance plans are a must for users looking to prolong the life of their generator equipment. For generators in critical applications, such as standby generators at hospitals, data centers and laboratories, generator maintenance plans are an absolute must.

Some components of a scheduled maintenance plan may be as simple as the user making sure generator exercisers are in place and working properly. These kick on the generator at set intervals to verify that everything is working properly.

Load bank testing is another critical element in a preventative generator maintenance plan. This test artificially boosts the load placed on the generator, usually to about the height of the generator’s output capacity. This helps to erase any effects of wet stacking or other buildup, and to verify that a generator is actually capable of performing at its peak output rate. It is generally recommended that load bank testing be conducted at least once per year.

The ambient conditions in which a generator operates will also have an effect on how often it should be serviced. Dust, moisture, salinity, altitude and extreme temperatures will all have a bearing on how often routine generator maintenance should be conducted.

In general, regularly scheduled “lifecycle” maintenance can save time and money by preventing downtime, allowing for small issues to be addressed before they become large ones and by prolonging the service life of the generator.


As is the case in many sectors of the power generation industry, the EPA’s final Tier 4 regulations are shaking up the way we buy and maintain diesel generators. Many of the diesel generators designed to meet Tier 4’s new emission standards are even less tolerant to light loading than previous models were. This is largely due to the fact that the selective catalytic reduction (SCR) components, which were introduced to reduce NOx emissions, must operate within a very narrow temperature range.

It’s also important to realize that final Tier 4 diesel generators cannot be operated without the additive diesel exhaust fluid (DEF). DEF is a non-hazardous solution that’s sprayed into the exhaust stream of diesel engines to help to reduce NOx emissions. In addition to verifying a Tier 4 diesel generator is running with the proper levels of DEF, it’s also key to verify beforehand that a particular type of DEF is approved for use with the specific generator model.

Final Tier 4 engine standards are tweaking best practices for running diesel generators efficiently. While some of the effects are new to all of us, it’s always best to consult experienced engineers who know how this type of machinery will function with new components and additives. Consulting a professional before any adverse effects of inefficient operation have time to add up will help to prolong the life of final Tier 4 generator equipment.

Chris Roach, Director of Roeslein Alternative Energy, accepting the 2016 Groundbreaker of the Year Award during the general session of the International Biomass Conference and Expo in Charlotte, NC on April 12, 2016.

Roeslein Alternative Energy was named the 2016 Groundbreaker of the Year by BBI International, at the annual International Biomass Conference and Expo in Charlotte, North Carolina on April 12, 2016.

Roeslein Alternative Energy (RAE) has recently launched a significant project, which warrants the nomination for this award. RAE has partnered with Smithfield Hog Production (SHP) of Missouri. RAE is utilizing SHP’s hog manure lagoons by placing impermeable covers over them in order to anaerobically digest the manure to create methane gas. The captured methane will then be refined and used as a renewable natural gas. Once refined the gas will then be injected into main grid pipelines, and accessible to millions. Along with manure conversion, RAE looks to utilize marginal and highly erodible land and restore them back to the native prairies that they once were. It is the goal of RAE to restore ultimately 200,000 acres of land to native prairies which will boast natural rehabilitation of habitats for plants and wildlife.

“Being a relatively young company, many in the industry are not aware of our advances on this project. Attending this conference and expo, was a way to spread the word,” said Chris Roach, Director for Roeslein Alternative Energy. “However, by receiving this award, not only was it a true justification of all the hard work and dedication we have been pouring into our projects, it helps accelerate this process and get others on board with what we are doing.”

The Groundbreaker of the Award is given to one company who is nominated and voted on by BBI International, a globally recognized bioenergy events and trade magazine company, and a committee for the International Biomass Conference and Expo. This award is in recognition that significant quantities of money and energy must be invested into a bioenergy project before construction can begin. Companies and organizations that reach the groundbreaking stage represent the minority of potential bioenergy projects. The dedication and perseverance needed to navigate design, funding, permitting, purchase agreements and community acceptance indicates extreme aptitude worthy of acknowledgment. The Groundbreaker of the Year Award recognizes the company or organization that has significantly advanced the bioenergy industry by breaking ground and making meaningful headway on a commercial scale biomass-to-energy project.

Roeslein Alternative Energy (RAE) was founded in 2012 as an operator and developer of renewable energy production facilities that converts agricultural and industrial wastes, along with renewable biomass feedstocks to renewable natural gas and sustainable co-products. RAE engages in these business operations with a focus on incorporating native prairie restoration. RAE is a limited liability corporation with its principal offices located in St. Louis, Missouri.
