Who We Are
Who We Are
We are a multidisciplinary team of mechanical engineers, energy modelers, compliance specialists, and seasoned construction managers. From navigating the complexities of Local Law 97 to deploying advanced 3D BIM models for HVAC electrification, we bring decades of localized expertise to the five boroughs. Whether we are advising a Co-op board on protecting their reserve capital or helping a commercial asset manager maximize their Net Operating Income (NOI), we serve as a dedicated technical advocate at every stage of the building lifecycle.
Partnering with architects, developers, owners, and project teams, we seek opportunities with unique challenges, first-of-a-kind projects, and buildings that strengthen their surrounding environment. Our consultants are continuously learning so we can create better buildings for our partners, people, and the planet.
OUR IMPACT
A Partner You Can Trust
Navigating New York’s aggressive energy mandates requires more than just high-level engineering— it demands boots-on-the-ground execution. We are committed to providing property owners with actionable decarbonization roadmaps, aggressive financial advocacy for rebates and incentives, and end-to-end accountability. From the initial ASHRAE-level audit to the final mechanical installation, we serve as your dedicated technical advocate to ensure your building performs exactly as designed.

OUR Difference
The YaFa Difference
A theoretical decarbonization roadmap is useless if it fails during implementation. We provide a single point of accountability to ensure the systems we design are the exact systems that get built.
- End-to-End Accountability: We eliminate the friction between design, contractor procurement, and construction. By acting as your owner’s representative, we oversee comprehensive bid leveling, enforce strict MEP design specifications, and actively manage construction to prevent costly change orders and schedule delays.
- Data-Driven Precision: We eliminate the guesswork from heavy capital improvements. Utilizing ASHRAE-standard energy audits and advanced digital twin simulations, we validate the financial payback and performance metrics of every mechanical upgrade before a single dollar is spent.
- Aggressive Financial Advocacy: Deep energy retrofits require significant capital. We act as your financial liaison, aggressively pursuing maximum funding through NYSERDA (FlexTech, AMEEP), the NYS Clean Heat Program, and Con Edison commercial rebates. By optimizing green financing and utility incentives, we drastically reduce your out-of-pocket costs and accelerate your project’s ROI.
- Future-Ready Integration: Modern buildings require more than just efficient boilers. We specialize in deploying secure Building Management Systems (BMS) and IoT environmental sensors, ensuring your physical mechanical equipment and digital controls operate in seamless, automated harmony while keeping your operational technology (OT) network hardened against cyber threats.
OUR Difference
Our Commitment
At YaFa Building Tech, our mission is straightforward: to deliver frictionless construction processes, protect your capital, and transform your property into a highly efficient, fully compliant, and future-proofed asset.
A Message from the Founder
When we established YaFa Building Tech, it was out of a simple, urgent realization: New York City’s property owners, developers, and Co-op boards were being left to navigate a chaotic regulatory landscape entirely on their own.
Between the looming financial penalties of Local Law 97, the complexities of securing utility rebates, and the sheer logistical nightmare of upgrading mechanical systems in occupied buildings, the pressure on real estate assets has never been higher. I saw too many boards and asset managers draining their capital reserves on disjointed engineering plans that contractors ultimately failed to execute.
We built this firm to be the antidote to that frustration. We aren’t just an engineering firm that hands you a blueprint and walks away; we are your dedicated partners in the field. Our goal isn’t simply to help you check a compliance box—it’s to aggressively protect your asset’s value, shield your shareholders from unnecessary costs, and build a sustainable, high-performing future for your property.
We are proud to be your technical advocates, and we treat every dollar of your reserve capital as if it were our own.
Welcome to a better way to manage your building’s future.
Sincerely
Ayman Helo

Our Core Competencies
1
Advanced Energy Modeling
We eliminate the guesswork from heavy capital improvements. Our engineers utilize state-of-the-art digital twin simulations and advanced energy modeling software to create a virtual replica of your building’s operational profile.
This technology allows us to test the impact of various mechanical upgrades—from lighting retrofits to full electrification—in a simulated environment. By doing so, we can validate the exact financial payback and carbon reduction metrics of a project before you spend a single dollar on construction.
2
Financial Advocacy
At YaFa Building Tech, we treat your reserve capital as if it were our own. We understand that funding a major mechanical overhaul is one of the most stressful challenges a Co-op board or commercial asset manager will face.
Our dedicated incentive team specializes in identifying and securing every available dollar of green financing, including C-PACE and utility rebates. We structure our project timelines around incentive payout milestones to ensure your cash flow is protected throughout the retrofit process.
3
Construction Management
A theoretical decarbonization roadmap is useless if it fails in the field. We bridge the costly gap between high-level engineering design and real-world construction execution by acting as your on-site project manager.
We enforce strict MEP design specifications, actively manage general contractors, and monitor installation quality. By providing a single point of accountability, we prevent scope creep, eliminate costly change orders, and ensure your building is handed over fully commissioned.
