RetroCore™ | Upgrade Management by Apollo Energies

Why Upgrade Projects Fail

Contractors replace equipment. RetroCore™ corrects the building.

Most energy audit reports include recommendations. Property owners use those recommendations to hire contractors. But contractors often interpret the project as a replacement job, not a building performance project.

The result is usually the same system, just newer and more efficient. The building’s underlying problems remain.

01. Oversized HVAC: Systems are routinely oversized by 25% or more to avoid comfort complaints and callback risk.
02. Leaky Buildings: Too much air moves through the structure, and the building envelope cannot hold conditioned air.
03. Incomplete Upgrades: Equipment gets replaced before air sealing, insulation, duct leakage, and envelope problems are corrected.

Building Performance Logic

“Replacing inefficient equipment inside an inefficient building only preserves the original design problem.”

RetroCore™ corrects the building first, then optimizes the systems.

The RetroCore™ Methodology

RetroCore™ starts with the principle that the building envelope must be corrected before major mechanical upgrades are performed.

We mandate air sealing and proper insulation as the base upgrade. From there, we improve HVAC, water heating, lighting, ventilation, controls, and other energy-consuming components.

Envelope First

Air sealing and insulation are treated as the foundation of the upgrade scope.

System Optimization

HVAC and energy-consuming systems are upgraded after the load is reduced.

// RetroCore™ Upgrade Logic

IF (building_envelope_leakage === true) {

execute_air_sealing_scope();

install_proper_insulation();

// Reduce load before equipment selection

} THEN {

right_size_mechanical_systems();

optimize_energy_consuming_components();

}

We Write The Scope. Contractors Do The Work. We Verify The Result.

Contractors know how to swing the hammer. RetroCore™ gives them a different nail to use: the methodology that produces measurable energy savings.

We develop the detailed scope of work, explain why each item must be completed exactly as described, and inspect the work before payment is approved.

Contractor Accountability

01 Contractors enter into a RetroCore™ project agreement with Apollo Energies.
02 The approved Scope of Work defines exactly what must be installed.
03 All upgrades are inspected before final payment is approved.
04 You are not left fighting with the contractor to fix work that should have been done correctly from the start.
