When selecting your energy solutions partner, ask them to provide guidance on these four essential factors for project delivery and success: legal, technical feasibility, financial soundness, and strict environmental compliance.
 

Below is a list of common problems and solutions. 

COST:

Problem:

• Building owners sometimes fear they are not sufficiently knowledgeable to understand the technical impacts of system design and selection on promised ROI.
• Concerns that the project may end up costing the building owner more than planned.
• Confusion on the best financing options to secure desired outcomes.
• Uncertainty about the impacts of project administration on incentives and Renewable Energy Credits (RECs).

Solution:

• Carefully examine the project structure and understand the duties of each team member: contractor, consultant, or structured financing arm.
• Evaluate project ROI and IRR over the lifecycle of the system, including maintenance and overhaul costs.
• Allow the project to be technology-agnostic, and select equipment based on site-specific applications.
• Demand the team provide an energy model for the project with clearly called-out assumptions so that the proposed ROI is the delivered ROI.
• When packaging the project scope to include items outside the primary DE with an Energy Services Agreement (ESA) or Power Purchase Agreement (PPA), make sure the scope is clear and deliverables are concise.
• Ensure the terms of the ESA or PPA lock in savings over the lifecycle of the project, including planned maintenance, unplanned breakdowns, engine overhauls, and scheduled rebuilds. Make sure the agreement states which party is responsible for each.

Understanding operating costs are covered within your budget or Energy Service Agreement (ESA).

Issues Working with Utilities

Problem:

When working with utilities for Combined Heat and Power (CHP) installations, major challenges include potential revenue loss for the utility due to reduced electricity sales from the CHP system, complex interconnection procedures, concerns about grid stability impacts, difficulty in accurately forecasting CHP output, and the need for potentially significant infrastructure modifications to accommodate the new generation source. All of these can lead to increased costs and regulatory hurdles for project development. Integrating a CHP system into the grid requires detailed planning and coordination with the utility, including technical specifications, interconnection studies, and potentially upgrades to the local distribution network.

Solution:

• Be patient.
• Be prepared that it may take more time than anticipated for final utility acceptance.
• Understand that final utility witness tests may delay final commissioning of the project.
• Foster open communication between utilities and potential CHP developers to address concerns early in the project planning stage.
• Work with a provider that has a strong relationship with local utilities to keep the process smooth.

Failure to Meet Regulatory Compliance & Incentive Requirements

Problem:

• Missing efficiency targets disqualifies projects from rebates/incentives.
• Non-compliance with EPA emissions regulations for CHP leads to fines.

How We Prevent It:

• Work closely with utility programs to ensure eligibility for rebates.
• Use low-NOx catalysts for emissions control to meet environmental standards.
• Handle all permitting & interconnection approvals upfront.

Addressing the Challenges of Aging Building Systems:

Problem: Integrating CHP with existing infrastructure, including steam and hot water distribution systems, can be technically challenging, requiring specialized engineering expertise.

Recommended Actions:

• Analyze current energy consumption to identify potential inefficiencies.
• Make sure that CHP is the correct equipment for your current usage.

Improper Sizing & Load Calculation Errors or Incorrect Equipment

Problem: Incorrect equipment size leads to insufficient heating/cooling or power generation, or excessive cycling.

How We Prevent It:

• Conduct detailed load calculations using ASHRAE standards.
• Perform thermal and electrical demand analysis for CHP to match power output to actual site needs.
• Use real-world operating data and simulations before finalizing system size.

Poor System Integration & Controls Issues

Problem: Improper coordination between HVAC, CHP, and BMS (Building Management System) leads to inefficiencies or equipment conflicts.

How to Prevent It:

• Pre-engineer system design to ensure seamless HVAC-CHP integration.
• Implement smart controls that adjust system output based on real-time demand.
• Optimize building performance with a well-balanced control system that ensures seamless building-wide coverage. Failure to do so can lead to system conflicts and energy inefficiencies.

Incorrect Piping, Ductwork, and Ventilation

Problem:

• Incorrect duct sizing reduces airflow efficiency.
• Poor piping layout causes pressure losses in CHP heat recovery loops.
• Inadequate ventilation leads to overheating or backdrafting.

How We Prevent It:

• Use CFD modeling (Computational Fluid Dynamics) for airflow and thermal analysis.
• Use HAPP for proper load calculations and sizing of equipment to meet code and energy standards.
• Properly size and insulate hydronic piping to minimize energy losses.
• Ensure ventilation codes compliance (NFPA, ASHRAE, and local building codes).

Lack of Commissioning & System Testing

Problem:

• Systems are installed but not properly commissioned, leading to long-term inefficiencies.
• No validation of setpoints, alarms, or controls.

How We Prevent It:

• Full commissioning process with functional testing at each phase.
• Verify all safety interlocks, setpoints, and emergency shutdown procedures.
• Provide as-built documentation and operational training for facility staff.

Electrical Failures & Grid Synchronization Issues (for CHP)

Problem:

• Improper generator synchronization with the grid can cause power surges or system shutdowns.
• Poor-quality electrical connections lead to overheating or failures.

How We Prevent It:

• Use high-precision paralleling controls to match CHP output with grid requirements.
• Implement protective relays to prevent phase mismatches.
• Use infrared thermography for proactive fault detection during installation.
• Install the equipment per the manufacturer’s instructions and design.

Ignoring Maintenance & Serviceability

Problem:

• Missed maintenance overhauls.
• Lack of understanding regarding required maintenance for ensuring system lifecycle.

Solutions:

• Provide detailed O&M manuals and support.
• Follow manufacturer O&M schedules.
• Engage with experienced service providers who offer comprehensive maintenance agreements and monitoring. This ensures regular inspections, preventive maintenance, and prompt response to any service requests to maximize uptime.

Navigating energy projects, particularly CHP installations, requires careful consideration of costs, utility interactions, regulatory compliance, building system compatibility, and proper equipment sizing. By proactively addressing these potential challenges through thorough planning, expert partnerships, and adherence to established standards, organizations can mitigate risks, maximize efficiency, and ensure the successful implementation of their energy solutions.

The post Equipment Upgrades Pitfall and Solutions appeared first on Controlled Air.

Controlled Air is currently tackling this exact challenge at the historic Capitol Theatre, transforming its cooling infrastructure to meet modern standards.

The Challenge: Replacing a Century-Old hvac Concept

Every historic building has a story, and the Capitol Theatre is no exception. The venue’s original cooling system dated back to the 1920s. In those days, state-of-the-art climate control meant placing massive blocks of ice in front of large industrial fans to push cool air through the auditorium.

While that primitive system was a marvel a century ago, today’s packed houses require precise, reliable, and energy-efficient cooling. To protect the venue’s reputation and ensure patron comfort, the ownership team partnered with Controlled Air to replace the aging infrastructure with a high-performance modern chiller plant.

The Solution: A Two-Phase Modernized hvac system

With the purchase order authorized, our team transitioned from planning straight into the active installation phase. The scope of work focuses purely on a complete HVAC chiller plant upgrade, designed to deliver 44°F supply chilled water with a 10°F temperature differential.

To minimize disruption and maintain project clarity, the workflow was structured into two distinct phases:

• Phase 1 (Design & Coordination): This initial phase involved site verification, equipment selection confirmation, and creating detailed HVAC design drawings to clear the way for local permitting.
• Phase 2 (Construction & Installation): With permits cleared, we are actively executing the physical installation, which includes cutting and capping the old 4-inch piping, rigging the new equipment onto the roof, and integrating the system controls.

High-Performance HVAC Equipment Lineup

To deliver the reliability and quiet operation an active theater environment demands, we selected a 115.9-ton YORK air-cooled scroll chiller utilizing eco-friendly R-454B refrigerant and low-sound variable speed drive (VSD) condenser fans. Circulating the water are two Grundfos inline chilled water pumps with built-in variable frequency drives, installed discreetly inside the attic space next to the existing 5-foot by 8-foot chilled water coil. The entire system is supported by heavy-duty infrastructure, including a Bell & Gossett air and dirt separator, Wessels and Amtrol ASME-rated tanks, and an Axiom glycol feeder system to ensure reliable fluid management and freeze protection.

The new chiller modules will be securely mounted on specialized 12-foot structural equipment support rails on the roof adjacent to the old unit, keeping the rooftop organized and secure.

Streamlining Complexity: Serving as the Owner’s Representative

Large-scale mechanical upgrades in historic properties are rarely simple HVAC jobs. They require careful choreography between multiple trades. To alleviate the logistical burden on the theater’s executive team, Controlled Air is stepping into an expanded role, representing the ownership team as the primary Owner’s Representative.

In this role, we are directly coordinating and engaging all specialized contractors on-site, including:

• General Contracting
• Asbestos Abatement
• Structural Steel Fabrication
• Electrical Infrastructure
• HVAC Installation and Controls

By serving as the central point of contact, we ensure that the structural, electrical, and architectural modifications handled by external New York licensed professionals align perfectly with our mechanical timeline. This turnkey approach keeps the project moving smoothly toward completion without draining the theater’s internal management resources.

Looking Ahead

This project stands as a prime example of Controlled Air’s full project management capabilities. We don’t just drop equipment on a roof. We engineer, design, price, and manage complex mechanical overhauls from conception to final commissioning.

We will share more updates and photos as the Capitol Theatre project progresses toward its final startup and testing phases. Stay tuned to see how we blend 21st-century comfort with 20th-century charm.

The post Historic Capitol Theatre HVAC retrofit appeared first on Controlled Air.

Controlled Air was asked to review the current equipment and provide options to: 

• Bring operating room air changes into compliance with current code requirements 

• Resolve persistent humidity issues 

• Improve temperature and comfort control for surgical staff 

HVAC Engineering Assessment 

A comprehensive evaluation by Controlled Air’s in‑house engineering team determined that the existing systems were originally designed in the early 1990s and no longer met modern operating room requirements. 

Key HVAC System deficiencies identified included: 

• Air handling equipment undersized for effective dehumidification 

• Insufficient reheat capacity to maintain staff comfort 

• Inability of the central chilled water system to deliver the low water temperatures required for proper latent moisture removal during summer conditions 

• Operating room airflow levels substantially below the current minimum requirement of 20 air changes per hour 

These conditions contributed to challenges in maintaining temperature, relative humidity, and airflow compliance within the surgical suites. 

Controlled Air’s Design/Build Solution 

Recognizing the urgency and regulatory importance of these issues, the hospital elected to move forward with Controlled Air’s design/build solution. 

The proposed system retrofit includes: 

• A new dedicated air handling unit capable of delivering code‑mandated airflow rates 

• A chilled water coil selected to achieve the desired leaving air temperature at increased airflow, ensuring proper dehumidification 

• A new air‑cooled chiller engineered to supply lower chilled water temperatures independent of the existing central plant 

To enhance system reliability, the design incorporates a remote evaporator configuration that eliminates the need for glycol antifreeze. This approach allows a direct tie‑in to the hospital’s existing chilled water system, providing redundancy in the event of air‑cooled chiller downtime. 

Project Status and Next Steps 

The project is currently under contract, with completion scheduled for the end of this year. 

A parallel phase of work will add reheat coils and upgraded controls in surgery support areas, further improving occupant comfort while maintaining precise relative humidity control within the operating suites. 

Why It Matters 

By addressing airflow deficiencies, improving dehumidification, and adding system redundancy, the Hospital will gain: 

• Safer surgical environments with consistent temperature and humidity control 

• Improved staff comfort and performance during long procedures 

• Reduced regulatory and accreditation risk through code compliant design 

• Greater system resilience, minimizing downtime and operational disruption 

• A HVAC System ready for increasing standards and regulations.  

A well-designed operating room HVAC system is not just a facilities upgrade, it is a direct investment in patient care quality, clinical efficiency, and long-term operational reliability.

At Controlled Air, Inc., we eliminate those friction points through our Design-Build delivery. By integrating engineering, custom fabrication, and installation into a single-source solution, we take full responsibility for your facility’s climate and energy future. Not only does it save time, but it saves cost as well, by eliminating the need for a separate engineer and/or construction manager.  

Design-Build vs. Traditional Plan-Spec 

Why Single-Source Responsibility Wins 

1. The “No Finger-Pointing” Guarantee 

In a typical project, if a control sequence fails or a unit doesn’t fit the roof curb, the contractor blames the engineer, and the engineer blames the installer. With Controlled Air, that conflict is eliminated. Because we are the engineer and the installer, we own the outcome. If a challenge arises, we solve it internally without the multiple change orders. 

2. Accelerated “Speed to Market” 

Time is the greatest cost of construction. Our Design-Build model allows us to overlap phases. We can begin site preparation, equipment procurement (critical for long-lead items), and in-house duct fabrication while the final engineering stamps are being applied. This typically reduces project schedules by 10–30%. 

3. In-House Precision 

Our Branford facility houses specialized sheet metal fabrication and piping departments. Unlike firms that outsource these critical components, we manufacture to the exact specifications of our design team. This ensures that what is drawn in CAD is exactly what is installed in the field. 

The Specialized Advantage: Efficiency-Driven Design 

While the Design-Build model provides the structure, our specialty in energy efficiency provides the value. We don’t just build systems that work; we build systems that pay you back.

• Our Energy Specialty: Because energy efficiency is our core focus, it makes for a better Design-Build process. We use advanced modeling to “right-size” equipment, ensuring you aren’t paying for excess capacity that wastes energy and increases maintenance costs. 
• Integrated Controls: We design the mechanical hardware and the Building Automation System (BAS) simultaneously. This ensures “native” communication between systems, preventing the energy-wasting “fighting” between heating and cooling cycles common in piecemeal installs. 
• Futureproofing: Our designs account for 2026 sustainability standards and ROI-driven technologies like Gas Heat Pumps and Cogeneration (CHP) from the very first sketch. 

Long-Term Facility Value 

An HVAC system is a 20-year investment. A Design-Build project with Controlled Air focuses on the Total Cost of Ownership, not just the initial bid. 

• Serviceability by Design: Because we also provide 24/7 service, our engineers design systems that are actually maintainable. We don’t bury components in inaccessible corners; we design for a lifetime of easy access and lower repair costs. 
• Enhanced Asset Value: A high-efficiency, well-documented Design-Build system increases a building’s “Green” rating and marketability, protecting the owner’s equity against rising utility costs. 

Partner with Controlled Air, Inc. 

Since 1980, we have been the premier Design-Build partner for general contractors, architects, and facility owners across Connecticut and Rhode Island. Let us take the complexity out of your next mechanical project.

The Section 179D Energy Efficient Commercial Buildings Deduction, a staple of the industry for two decades, is officially scheduled to sunset on June 30, 2026, under the One Big Beautiful Bill Act (OBBBA).

For building owners, developers, and designers, the message is clear: If you haven’t started construction by mid-summer, you are leaving up to $5.94 per square foot on the table.

What’s at Stake? (The 2026 Numbers)

Thanks to the latest IRS inflation adjustments (Rev. Proc. 2025-32), the 2026 deduction rates are the highest they have ever been. Depending on your project’s labor standards and efficiency gains, the potential savings are substantial.

The Two Pathways

1. The Base Rate: For projects that achieve at least 25% energy savings but do not meet specific labor requirements, the deduction ranges from $0.59 to $1.19 per sq. ft.
2. The Bonus Rate (PWA): For projects that meet Prevailing Wage and Apprenticeship (PWA) requirements, the deduction jumps significantly to a range of $2.97 to $5.94 per sq. ft.

To calculate your maximum potential benefit, you can use the following logic:

$$\text{Total Deduction} = \text{Building Area (sq. ft.)} \times \text{Applicable Dollar Value (up to \$5.94)}$$

For a 100,000 sq. ft. warehouse or office complex, that is a swing of nearly $600,000 in immediate tax relief.

The “Beginning of Construction” Trap

The most critical detail of the 2026 sunset is the definition of “Beginning Construction.” You do not need to finish the project by June 30, but you must prove you started. The IRS typically recognizes two methods:

• The Physical Work Test: This requires “significant physical work” to have begun. In our industry, this means foundation excavation, setting anchor bolts, or permanent installation of components. Preliminary site clearing or design work does not count.
• The 5% Safe Harbor: You must have paid or incurred at least 5% of the total cost of the energy-efficient property before the deadline.

Why Proactive Planning Matters Now

Waiting until May to “talk to the engineers” will be too late. To secure this deduction, a project requires:

1. Energy Modeling: A third-party professional must model the building against the ASHRAE 90.1 standards to certify the 25%+ savings. Although the IRS does not mandate a specific modeling protocol, it is an accepted way of demonstrating the savings for the deduction. The modeling procedures come from regulation and practice. Controlled Air utilizes Carrier’s Hourly Analysis Program (HAP) to provide the precise energy modeling required for high-performance building design. This software is an industry standard for performing the 8,760-hour simulations necessary to demonstrate compliance with ASHRAE 90.1 and federal tax requirements. By leveraging this ASHRAE-approved tool, we ensure your facility’s projected energy savings are both technically accurate and professionally certified.
2. PWA Documentation: If you are aiming for the $5.94 bonus rate, your payroll and apprenticeship records must be airtight from day one.
3. Designer Allocation: For government or non-profit buildings, the tax-exempt owner can allocate this deduction to the Primary Designer (architect, engineer, or design-build contractor). This is not automatic, but an eligible entity can allocate the deduction.

The Bottom Line

Section 179D has been a cornerstone for financing HVAC retrofits, lighting upgrades, and high-performance building envelopes. After June 30, that “extra” capital disappears from the market.

Is your pipeline ready? Our team is currently prioritizing site audits and energy modeling for clients looking to lock in their 179D eligibility before the summer deadline.

The post The Power of Knowing: Why Energy Evaluations Are Essential for Your Business appeared first on Controlled Air.

In today’s world, sustainability is no longer just an option; it’s a necessity. Controlled Air has long been a leader in delivering full-service energy solutions to clients across the New England area, bringing expertise in designing and engineering advanced energy systems – including gas heat pumps (GHPs), co-generation combined heat and power (CHP), microgrids, and energy management systems.  

Since joining Yanmar Energy Systems in 2022, Controlled Air has been able to expand its operations and accelerate its mission, furthering its founder’s vision of creating smarter, more efficient energy solutions. Now, as an integral part of Yanmar, the company continues to push the boundaries of energy innovation, helping businesses across North America reduce emissions and optimize energy use. 

Vincent Chiocchio, President of Controlled Air and Yanmar Energy Systems North America, underscores their mission: “Building sustainability is the way of the future. We design, engineer, and install systems tailored to each building, ensuring long-term performance. And beyond installation, we continue to maintain them for the life of the building.” 

Energy Efficiency at Elm City Bioscience Center 

One of Controlled Air’s standout projects is the transformation of 55 Church Street in New Haven, Connecticut, home to the Elm City Bioscience Center. This office building has been reimagined as an energy-efficient space tailored for life science companies. 

Darlene Reilly, Director of Real Estate at The Hurley Group, explains, “Our goal was to create an asset in downtown New Haven that supports the growth of the life science community. Controlled Air has worked with us to maintain systems for our existing office tenants while also designing and building solutions to accommodate new life science tenants.” 

By integrating state-of-the-art heating, ventilation, and air conditioning (HVAC) solutions, Controlled Air improved energy efficiency and reduced the building’s operational costs and carbon footprint. “The more energy-efficient our buildings are, the lower our operating costs – and the greater the reduction in carbon emissions, helping to create a better planet for everyone,” Reilly adds. 

HVAC and Energy Management with Advanced Technologies  

One of the key innovations implemented at the facility is the use of Yanmar’s GHPs. These systems operate on natural gas, significantly reducing electrical demand while maintaining high efficiency. Todd Arnold, Senior Project Manager at Controlled Air, explains, “By using these GHPs, we’re creating a more sustainable future for both our clients and the wider New Haven community.” 

Controlled Air also introduced Yanmar Hydrobox technology to design a chiller plant, which integrates seamlessly with the GHPs. The Yanmar Hydrobox delivers chilled or hot water using its powerful VRF heat exchanger, transferring the energy created by the Yanmar GHP to any hydronic or boiler system.  

“The Yanmar Hydrobox communicates seamlessly with the GHP outside. All three Hydroboxes in the system work together, operating at peak efficiency based on demand,” Arnold explains.   

Controlled Air’s integration of Yanmar’s GHP technology at 55 Church Street serves as a model for future energy-efficient building projects. 

“In this application, instead of relying on the building’s limited electrical supply to power air handlers for lab buildouts or office spaces, we’re able to utilize Yanmar GHP technology. By using natural gas as the primary energy source instead of electricity, we can reduce strain on the building’s power infrastructure while maintaining efficient climate control,” Arnold adds.   

Furthermore, Controlled Air’s energy management solutions incorporate advanced analytics, allowing facility managers to optimize their energy use based on real-time data. This predictive approach reduces costs while enhancing system reliability.   

Smart, Efficient, and Quiet Chiller Systems 

Another major component of the renovation at this site involved upgrading the building’s aging chiller system. Controlled Air replaced outdated 1970s chillers with modern chiller packages featuring turbo-core compressors.  

Unlike traditional oil-based systems, these advanced compressors use magnetic bearings, improving efficiency, durability, and significantly reducing noise levels – an essential factor in a busy urban environment. 

Arnold explains: “What’s great about these chillers is their turbo core compressors, which use magnetic bearings. This design enhances efficiency and extends the lifespan compared to a standard scroll compressor.” 

These upgraded chillers integrate seamlessly with the building’s infrastructure, minimizing disruptions during installation. Predictive maintenance and remote monitoring ensure operational reliability, reducing the risk of unexpected downtime.
