Monadnock Conservatory Project: High-Performance VRF HVAC & Commercial Mechanical Installation in Keene, NH

A Benchmark for Sustainable Commercial HVAC & Plumbing in New England

At Denommee Plumbing, HVAC & Electric, we don’t just install mechanical systems—we help build the future of high-performance, energy-efficient commercial spaces across Massachusetts and Southern New Hampshire.

The Monadnock Conservancy headquarters project in Keene, NH is a perfect example of what’s possible when innovative design, sustainability goals, and expert commercial HVAC installation come together.

This project now stands as a regional benchmark for net-zero-ready construction, showcasing advanced VRF HVAC systems, energy recovery ventilation, and high-efficiency plumbing systems—all delivered through coordinated execution by experienced professionals.

bout the Monadnock Conservancy Project

The Monadnock Conservancy’s new headquarters is far more than a commercial building—it’s a mission-driven space designed to reflect environmental stewardship and long-term sustainability.

Located on a redeveloped 3.5-acre site along Ashuelot Street in Keene, NH, the project transformed a previously underutilized parking lot into a vibrant, community-centered facility.

Key Features of the Development:

• Modern office space for organizational operations
• ADA-accessible community room (capacity ~50 occupants)
• Direct integration with Ashuelot River Park expansion
• Outdoor educational and recreational access points
• Designed for net-zero energy performance, with potential for net-positive output

Sustainability Elements:

• Rooftop solar photovoltaic system
• Wood-fiber insulation for reduced embodied carbon
• High-performance building envelope
• Low-impact, responsibly sourced construction materials

For projects like this, mechanical systems are not an afterthought—they are central to achieving performance goals.

Denommee’s Commercial HVAC & Plumbing Scope

Denommee Plumbing, HVAC & Electric was selected to deliver full mechanical scope installation, including commercial plumbing systems and advanced VRF HVAC infrastructure.

Our role required:

• Deep coordination with architects and engineers
• Real-time value engineering decisions
• Execution aligned with strict performance specifications

Commercial Plumbing Installation Scope

Our team installed a complete plumbing system designed for reliability, efficiency, and long-term durability.

Plumbing System Highlights:

• Full plumbing rough and finish for three commercial bathrooms
• Installation of two high-efficiency commercial water heaters
• PEX water distribution piping throughout the building
• PVC sanitary drainage systems engineered for performance and longevity
• Integration with energy-efficient building systems

Value Engineering Impact:

We worked closely with the project team to:

• Optimize material selection
• Improve installation efficiency
• Reduce overall project cost without sacrificing quality

VRF HVAC System Installation: Precision & Efficiency

A major highlight of the project was the installation of a Mitsubishi Variable Refrigerant Flow (VRF) system—one of the most advanced commercial HVAC solutions available today.

VRF System Overview:

• 4 outdoor condenser units
• 18 indoor units distributed throughout the building
• Zoned temperature control for maximum occupant comfort
• Simultaneous heating and cooling capabilities

Why VRF Was the Right Choice:

VRF systems are ideal for:

• Net-zero and high-performance buildings
• Multi-zone commercial spaces
• Energy-conscious property owners

They offer:

• Exceptional efficiency (reducing operational costs)
• Precise temperature control
• Reduced ductwork requirements
• Quiet operation

Energy Recovery Ventilation (ERV) & Fresh Air Systems

Indoor air quality is just as important as energy efficiency—especially in community-centered buildings.

ERV System Installation:

• Two Energy Recovery Ventilators (ERVs) installed
• Continuous fresh air delivery throughout the building
• Balanced ventilation system design

Benefits:

• Improved indoor air quality (IAQ)
• Reduced heating and cooling load
• Enhanced occupant comfort
• Supports net-zero energy goals

Custom Ductwork & In-House Insulation

Denommee self-performed critical system components to ensure quality and performance.

Our Scope Included:

• Complete fresh air ductwork installation
• Custom routing for optimal airflow distribution
• In-house insulation of ductwork and refrigerant piping

Why This Matters:

Proper insulation:

• Prevents energy loss
• Maintains system efficiency
• Reduces condensation risks
• Improves overall HVAC performance

Controls & System Integration

Commercial HVAC systems are only as effective as their controls.

Denommee coordinated:

• Third-party controls integration
• System communication between VRF, ERV, and building automation
• Commissioning support to ensure seamless operation

Supporting Net-Zero Commercial Construction

The Monadnock Conservancy project required alignment between mechanical systems and sustainability objectives.

How Denommee Delivered:

• Installed high-efficiency VRF systems to reduce energy demand
• Integrated ERVs to minimize energy waste
• Ensured airtight, insulated system performance
• Participated in collaborative design and execution

The result:
A building that is not only energy-efficient but future-ready.
