Smart Thermos

ENGINEERING METHODOLOGY

Smart Thermos is an engineering methodology for coordinating a building’s thermal envelope, climate-management systems, controls and project-appropriate energy technologies as one building system.

The methodology starts with a continuous, airtight envelope and coordinates windows, walls, roof and foundation with ventilation, heating, cooling and controls. Renewable generation and storage may be integrated where project conditions support them.

One Building System

The methodology treats the building as an interconnected system. The envelope reduces unwanted heat transfer and air leakage; climate systems manage comfort and indoor air quality; controls coordinate their operation; and optional energy systems are sized for the needs and conditions of the project.

Building Envelope

CONCEPTUAL METHODOLOGY

Windows and doors, glazing, insulated walls, roof and foundation, airtight junctions and thermal-bridge control form one continuous envelope designed to limit unwanted heat transfer and air leakage.

Climate Management

PROJECT-SPECIFIC INTEGRATION

Low-temperature heating, heat pumps, balanced ventilation with heat recovery and cooling are coordinated for the reduced loads of the building envelope.

Sensors & Control

CONFIGURABLE CAPABILITY

Temperature, humidity, CO₂, light, rain and wind data may support rule-based control of ventilation, shading, heating and cooling. Predictive AI remains future development.

Energy System Integration

PROJECT-SPECIFIC INTEGRATION

Photovoltaic generation, optional wind generation, battery storage and energy management may be coordinated where site conditions, engineering and local requirements support them.

Component technologies may be supplied by third parties. Smart Thermos describes their project-specific coordination as a building methodology; it does not replace product testing, engineering design or regulatory approval.

Climate-Specific Configuration

The book describes selected climate examples rather than one universal configuration. Each application requires project-specific analysis, component selection, testing and code review.

Cold & Very Cold

Prioritize heat retention, low-U-value glazing, airtight junctions and balanced ventilation with heat recovery.

Mixed & Temperate

Balance winter heat retention with summer solar control, shading and adaptable ventilation and cooling strategies.

Hot & Humid / Hot & Dry

Prioritize solar-control glazing and shading; in humid conditions, coordinate ventilation and moisture management with the cooling strategy.

Illustrative Wall Calculation

CALCULATED EXAMPLE

Source: Artur Petkov, Innovative Energy-Saving Systems: Smart Thermos, 2025, Chapter 3, simplified wall-resistance example.

TARGET THERMAL RESISTANCE: R = 4.0 m²·°C/W
WALL THICKNESS: 0.38 m
CERAMIC BRICK: λ = 0.70 W/(m·°C)
FOAM CONCRETE: λ = 0.15 W/(m·°C)
MINERAL-WOOL INSULATION: λ = 0.04 W/(m·°C)

Ceramic brick: R = 0.54 m²·°C/W; approximately 0.14 m of the assumed insulation is required to reach the example target.

Foam concrete: R = 2.53 m²·°C/W; approximately 0.06 m of the assumed insulation is required to reach the example target.
