Greenhouse Thermal Audit & Heating Strategy

345.00 $

Precision, not guesswork. A heating failure in January is catastrophic. Yet, most greenhouse heating systems are sized based on ‘rules of thumb’ rather than physics, leading to dangerous freeze events or wasteful fuel consumption.

We provide a forensic analysis of your structure’s thermal properties. By calculating the precise R-values of your glazing and the Delta-T requirements of your location, we deliver a Systems Specification ensuring your climate control is robust, efficient, and redundant.

Technical Specifications:

  • Fee: $345.00 CAD (Flat Rate).

  • Methodology: Standard Heat Loss Calculations.

  • Deliverable: Technical Report including BTU Load, Thermal Mass Assessment, and Insulation Strategy.

  • Prerequisite: Structure blueprints or detailed dimensions.

Support the Mission. Proceeds from this purchase directly fund the Avishan Cultivator Grant, empowering emerging horticulturists to launch community stewardship projects across the Temperate and Continental biomes. Invest in your garden, invest in the community.

Don’t fight the physics. Manage it.

A greenhouse is a solar collector by day and a radiator by night. The most common cause of crop failure in controlled environments is not pests or disease—it is thermal mismanagement.

Most growers guess their heating requirements based on square footage rules of thumb. This is dangerous. A glass structure loses heat differently than twin-wall polycarbonate, and a windy site strips heat away twice as fast as a sheltered one.

The Avishan Thermal Systems Analysis replaces guesswork with thermodynamics. We model your structure’s performance against local climate extremes to ensure your system can hold the line during the coldest night of the year.

The Delta-T Approach: We calculate the Delta-T (the difference between outside and inside temperature) specific to your climate zones.

  • Heating Load: We determine the exact BTU output required to maintain your target temperature.

  • Passive Regulation: We calculate the volume of Thermal Mass (water/stone) required to act as a Heat Battery, stabilizing dangerous temperature swings without using electricity.

  • Insulation ROI: We analyze where your structure is bleeding energy and calculate the efficiency gains of insulating north walls or foundation perimeters.

How It Works:

  1. Data Intake: You provide the dimensions, glazing materials (e.g., 6 mm Polycarbonate), and orientation of your structure.

  2. The Analysis: We run heat-loss calculations based on the surface area and U-values of your specific materials.

  3. The Report: You receive a Thermal Analysis Report detailing:

    • Peak Heating Load (BTUs).

    • Emergency Critical Low thresholds.

    • Passive Thermal Mass strategy.

Service Specifications:

  • Service Type: Technical Systems Analysis.

  • Fee Structure: $345.00 CAD (Flat Rate).

  • Deliverable: PDF Technical Report.

  • Scope: Suitable for Hobby, Semi-Commercial, and Conservatory structures up to 1,000 sq ft.

Note: This service provides thermal load calculations based on provided data. It does not include mechanical installation, electrical work, or guarantees against mechanical equipment failure.

Technical Scope & Thermodynamic Limitations:

  1. Theoretical Modelling Only: The Thermal Systems Analysis is a theoretical calculation predicated entirely on the structural metrics (R-Value, Surface Area) and environmental data provided by the Steward. It serves as a BTU estimation tool for procurement, not a certified mechanical engineering stamp or a building permit document.

  2. Data Fidelity: The accuracy of the heat-loss calculation is directly dependent on the precision of the input data. Avishan Garden is not liable for thermal failures resulting from incorrect glazing specifications, unsealed air leaks, or inaccurate dimensional measurements provided during the intake process.

  3. Exclusion of Trade Work: This service is strictly advisory. It does not include physical installation, gas fitting, or electrical rough-ins. All heating units and high-voltage thermostats must be installed by a licensed HVAC technician or electrician in accordance with the Temperate and Continental biomes Building Code.

  4. Extreme Weather Variance: Our calculations are based on historical climate norms for your reported hardiness zones. Avishan Garden assumes no liability for biological loss resulting from Force Majeure events, such as power outages, fuel shortages, or extreme polar vortex conditions that exceed the calculated design range of the equipment.
