The breathing home: how proper ventilation creates comfort and health in your house

lifehacks and tips
Georgia is a unique country with diverse climates: the humid, maritime air of its coastal regions; the harsh mountain climate with abundant snow and frost in winter and comfortable, cool summers; and the heat of the capital. In Tbilisi, when it's +35°C (95°F) outside, imagine a pleasant coolness inside without the draft from an air conditioner. In Batumi during the humid, cool months, imagine warm, dry rooms where windows don't "sweat." And in the kitchen, after cooking your favorite meals, imagine smells disappearing within minutes, without being absorbed into the sofa upholstery and curtains.

Imagine a home where it's easy to breathe in any weather. This isn't magic, but the result of a professionally designed ventilation system. It is the invisible lungs of your home, the foundation for your family's health, the preservation of your renovation, and true comfort. At KStudio, we believe ventilation should be designed in parallel with the interior design. This allows us to integrate the equipment (which often requires ceiling space) aesthetically and functionally, avoiding bulky ductwork and lost centimeters of ceiling height later on.

Our engineering systems specialist will explain in detail the types of ventilation for a private house or apartment, with special attention to our Georgian climate realities.

Types of ventilation:
which system "breathes" for your family?

The following types of ventilation exist (for residential spaces):

• Supply

• Exhaust

• Supply and Exhaust

• With Heat Recovery

• With Air Conditioning / Humidification / Dehumidification


Let's break down the main options, their strengths, and the problems they solve.

1
Supply ventilation
A system that forces fresh, pre-filtered outdoor air into the premises.
  • Advantages
    Provides a constant flow of oxygen, especially important with airtight double-glazed windows. Fights stuffiness.
  • Limitations
    Does not remove polluted air by itself. Pressure inside increases, forcing air out through exhaust ducts (e.g., in the kitchen and bathroom) or cracks.
  • Climate Considerations
    In Tbilisi, requires mandatory cooling of the supply air in summer (integration with air conditioning). In Batumi, requires heating in winter to avoid letting in cold, damp air.
Ideal as an "upgrade" for apartments with weak standard exhaust. Often used to supply clean air to bedrooms and children's rooms.

2
Exhaust ventilation
Actively removes odors, moisture, and pollutants from the areas where they are generated.
  • Advantages
    Effectively solves local problems: removes steam from the bathroom, kitchen odors, excess moisture from the laundry room.
  • Limitations
    Does not supply fresh air. Creates negative pressure, which is compensated by air intake through windows (with drafts and dust) or from other rooms.
  • Climate considerations
    Critically important in Batumi bathrooms to combat mold. In a Tbilisi kitchen during summer, it removes not only odors but also excess heat.
A powerful range hood above the stove and a separate fan in the bathroom are the absolute minimum in any home.

Supply and exhaust ventilation
The most effective and balanced option, featuring two independent systems: one supplies air, the other removes it.
  • Advantages
    Complete control over air exchange. You can set the precise amount of fresh air for each room.
  • Limitations
    More complex and costly installation, requires professional calculation.
  • Climate considerations
    The best solution for modern, energy-efficient homes. Allows cooled air from an air conditioner to be distributed evenly to all rooms in summer, and heated air in winter.
The "gold standard" for private houses and major apartment renovations. We design it concealed, for example, behind suspended ceilings.

Object LOFT
  • We implemented this solution at our LOFT project.
    In this apartment, we installed supply and exhaust ventilation – a solution ideally suited for double-height spaces with high ceilings. This is why such systems need to be planned during the initial design phase, not "added later."
Object LOFT
What determined our choice?
What did we focus on primarily when choosing the supply and exhaust principle?
  • Vertical air exchange

    The system's task isn't just to mix the air, but to create controlled flows so that fresh supply air also reaches the upper zone, creating an ideal climate in every part of the space.
  • Industrial aesthetics
    The system doesn't have to be hidden; it can be integrated into the design: spiral-wound air ducts in copper or galvanized steel; runs along columns or exposed beams; designer grilles and anemostats.
  • Separation of private and common areas
    Creating negative pressure in the "dirty" zones on the first floor and organizing separate supply lines to each room on the second floor.
  • Acoustics of open space
    Equipment (air handling units) must be low-noise or placed in a technical room (e.g., a walk-in closet or under the stairs). Air ducts must be sound-insulated.
  • Heat recovery – a key recommendation
    A supply and exhaust system with a heat recovery unit (preferably with a bypass for the warm season) saves energy by preheating the supply air in winter using the heat from the exhaust air, and pays for itself quickly.
  • Smart zoning of airflows
    Using automation and zone dampers allows the system not to condition the entire loft volume at once, but to work zonally: at night, supply to the living room is reduced, while it is maintained in the bedrooms.

Supply and exhaust ventilation
with heat recovery
An intelligent system where exhaust and supply air meet in a heat exchanger without mixing. Heat from the "dirty" exhaust air is transferred to the cold supply air in winter. In summer, the opposite happens: coolness from the air-conditioned room air cools the incoming hot air.
  • Advantages
    Savings on heating and cooling of up to 70-80%. You get fresh air at a comfortable temperature.
  • Limitations
    High initial equipment cost. Requires regular maintenance (filter replacement).
  • Climate Considerations
    Ideal for Tbilisi with its contrasting seasons. Pays for itself within a few seasons. In Batumi, it fights dampness by heating the supply air without significant energy costs.
An investment in health and long-term savings. We help select a model considering noise levels, which is important for bedrooms and children's rooms.

Ventilation with air conditioning, humidification, and dehumidification
A climate system where the supply air is not only filtered but also brought to ideal temperature and humidity parameters.
  • Advantages
    Absolute "turnkey" climate comfort. Solves all problems.
  • Limitations
    The most complex and expensive system. Requires space for equipment (often in a separate technical room).
  • Climate Considerations
    Provides coolness in summer and warmth in winter in Tbilisi.
    In Batumi, it removes excess humidity, protecting the home from mold in winter and humidifying the air dried out by air conditioners in summer.
This is the pinnacle of engineering design. We consider this option for premium-class properties or for families with allergy sufferers and young children, whose health directly depends on air quality.
KStudio recommendation
Focus on key zones!
  • KITCHEN
    This is the "lungs" of the home: A powerful exhaust zone above the stove, integrated into the overall supply and exhaust system, is mandatory here. It's a matter of not just comfort but also safety: effective removal of combustion byproducts, grease, and moisture.
  • CHILDREN'S ROOM AND BEDROOM
    These are health zones: In rooms where we restore our strength, a constant supply of fresh, clean, and silent air is critical. We design separate supply lines with night mode (minimal noise) and enhanced filtration. This is especially important for building a child's healthy immune system.
It is very important, before you start planning the renovation or reconstruction of your apartment or house, to think through the ventilation issue. Within the hot concrete walls of Tbilisi or the humid coastal area of Batumi – the climate of your home will depend not only on the goodwill of its inhabitants but also on the correct choice of the ventilation system.
Our task at KStudio is to turn this into a technically flawless
and aesthetically impeccable project.

Trust us to create an atmosphere where your family can
breathe easily. In any season.
