Commercial building owners are increasingly looking for ways to reduce energy costs, improve building performance, and upgrade aging systems without making large upfront capital investments. Because roofing and HVAC systems work together to influence a building’s energy consumption, some financing models combine both improvements into a single energy performance agreement.

A common question among commercial property owners and facility managers is:

What is an energy service agreement covering roof and HVAC together?

An energy service agreement covering roof and HVAC together is a financing and performance-based arrangement where an energy services company (ESCO) designs, installs, and manages energy-saving improvements while the customer pays through an agreed service payment structure. The project may combine roof upgrades, HVAC improvements, and other efficiency measures to reduce energy consumption and improve building performance.

What Is an Energy Service Agreement?

An energy service agreement (ESA) is a contract designed to fund energy improvements through expected operational savings rather than requiring the building owner to pay the entire project cost upfront.

Under a traditional approach:

• Owner pays for roof replacement

• Owner pays for HVAC upgrades

• Owner manages maintenance

• Owner receives future energy savings

Under an energy service agreement:

• Provider evaluates energy opportunities

• Provider designs improvements

• Provider may finance installation

• Provider monitors performance

• Owner pays according to the agreement

The goal is to align project costs with energy savings.

Why Combine Roofing and HVAC?

Roof and HVAC systems directly affect each other.

A poorly performing roof can increase:

• Heat gain

• Cooling demand

• HVAC operating hours

• Energy costs

An efficient roof can help HVAC systems operate more effectively.

Combining both systems allows owners to address the building envelope and mechanical systems together.

How Does a Roof + HVAC Energy Service Agreement Work?

Step 1: Building Energy Assessment

The provider evaluates existing conditions.

The assessment may include:

Roof Evaluation

• Existing membrane condition

• Insulation levels

• Solar reflectance

• Thermal performance

• Remaining service life

HVAC Evaluation

• Equipment age

• Efficiency ratings

• Operating schedules

• Maintenance history

• Energy consumption

The provider identifies opportunities for improvement.

Step 2: Develop an Energy Improvement Plan

The ESCO creates a proposed project.

The plan may include:

Roofing Improvements

Examples:

• Cool roof coatings

• Reflective membranes

• Added insulation

• Roof restoration

• Air barrier improvements

HVAC Improvements

Examples:

• High-efficiency units

• Variable-speed systems

• Controls upgrades

• Building automation systems

• Improved ventilation

Additional Measures

Projects may also include:

• LED lighting

• Solar systems

• Energy monitoring

• Water efficiency improvements

Step 3: Financing Structure

The provider and building owner agree on payment terms.

Possible structures include:

• Energy service agreements

• Performance contracts

• Equipment financing

• Third-party ownership models

The agreement defines:

• Project costs

• Payment schedule

• Performance expectations

• Maintenance responsibilities

Step 4: Installation and Commissioning

The provider coordinates improvements.

Work may include:

• Roof installation

• HVAC replacement

• System testing

• Energy monitoring setup

Commissioning verifies that systems operate as designed.

Step 5: Ongoing Monitoring

Many agreements include performance tracking.

Monitoring may measure:

• Energy usage

• HVAC performance

• Temperature conditions

• Savings results

This helps verify project outcomes.

What Are the Benefits of Combining Roof and HVAC Financing?

1. Lower Upfront Capital Costs

Owners can complete major improvements without paying the full cost immediately.

This is useful for:

• Office buildings

• Warehouses

• Retail properties

• Industrial facilities

2. Improved Energy Savings

A combined approach may improve:

• Cooling efficiency

• Building comfort

• Energy consumption

3. Better System Coordination

Roof and HVAC upgrades are designed together rather than separately.

Example:

A reflective roof may reduce cooling loads, allowing HVAC improvements to perform better.

4. Predictable Budgeting

Owners may replace unpredictable repair costs with planned payments.

5. Long-Term Asset Management

The agreement may include:

• Monitoring

• Maintenance

• Performance reporting

What Types of Roofing Improvements May Be Included?

Potential roof-related improvements include:

Reflective Roofing Systems

Examples:

• White membranes

• Cool roof coatings

• Reflective surfaces

Insulation Improvements

Examples:

• Additional insulation layers

• Higher R-value assemblies

Roof Restoration

Examples:

• Silicone coatings

• Acrylic coatings

• Waterproofing systems

Roof Replacement With Energy Goals

A complete replacement may be included when it improves building energy performance.

How Is an Energy Service Agreement Different From a Traditional Roof Contract?

Traditional Roof Project	Energy Service Agreement
Owner pays upfront	Payments spread over time
Focuses on roof condition	Focuses on energy performance
Owner manages savings	Provider may guarantee performance
Separate roof and HVAC decisions	Integrated building approach

How Is It Different From C-PACE Financing?

Both can support energy improvements but work differently.

C-PACE

• Repaid through property assessment

• Often used for energy and resilience projects

• Connected to the property

Energy Service Agreement

• Based on energy performance

• Often managed by an ESCO

• Payments may depend on agreement structure

The best option depends on:

• Project size

• Ownership goals

• Financing needs

• Building condition

Potential Challenges

Contract Complexity

Owners must understand:

• Payment calculations

• Savings guarantees

• Responsibilities

Long-Term Commitments

Agreements may last many years.

Owners should review:

• Transfer terms

• Termination clauses

• Maintenance obligations

Performance Measurement

Savings calculations must be clearly defined.

What Should Commercial Property Owners Ask?

Before signing an energy service agreement, owners should ask:

• Who owns the upgraded equipment?

• Are roof and HVAC costs separated?

• How are savings measured?

• Is performance guaranteed?

• Who handles maintenance?

• What happens if the building is sold?

What Documentation Is Needed?

Owners should maintain:

• Energy assessments

• Roof inspection reports

• HVAC evaluations

• Project specifications

• Installation records

• Performance reports

Common Mistakes

Upgrading HVAC Without Evaluating the Roof

Roof performance affects cooling loads.

Focusing Only on Equipment Cost

Long-term energy savings matter.

Not Defining Savings Measurement

Contracts should clearly explain calculations.

Ignoring Future Ownership Changes

Transfer provisions are important.

Frequently Asked Question

What is an energy service agreement covering roof and HVAC together?

An energy service agreement covering roof and HVAC together is a performance-based financing approach where an energy services provider designs, installs, and manages energy-saving improvements involving both the building envelope and mechanical systems. The project may include reflective roofing, insulation upgrades, HVAC replacements, controls, and other efficiency measures. The owner typically pays through a structured agreement designed around energy performance and long-term savings rather than paying the full cost upfront.

For Florida commercial buildings, combining roof and HVAC improvements through an energy service agreement can help reduce cooling costs, improve building efficiency, and modernize aging systems while managing capital expenses.
