Strategic reserve of naturally dried and long-term aged timber
DREVO Air Reserve— a system of selection, slow natural drying, climate stabilization and long-term storage of valuable wood in a dry air environment.
The project complementsDREVO Timber Reserve, where wood is preserved in water, swamps and anaerobic reservoirs.
If DREVO Water Reservecreates stained and mineralized wood, thenDREVO Air Reservepreserves the natural structure, elasticity, acoustic properties, colour and stability of the dry material.
DREVO Air Reserve is wood whose value is formed not by water, but by time, air and proper aging.
1. Main goal
Create a strategic reserve of high-quality dry wood for:
architecture;
restoration;
construction;
furniture;
shipbuilding;
musical instruments;
artistic processing;
precision carpentry;
museum and cultural projects;
scientific research;
transmission to future generations.
2. Difference from a regular warehouse
A regular warehouse stores material until it is sold.
DREVO Air Reservemanages timber as long-term natural capital.
Each batch:
selected according to purpose;
dries according to an individual regime;
receives a digital passport;
is regularly examined;
stored in a stable microclimate;
can be maintained for decades;
reserved for specific future applications.

For some species, full stabilization may occur more quickly, but strategic status is determined not only by humidity, but by the length of documented aging.
7. DREVO Air Reserve Stages
Stage 1 - Selection
Evaluated:
breed;
age;
dimensions;
straightness;
knottiness;
cracks;
rot;
density;
structure of annual rings;
genetic and historical value;
future appointment.
Stage 2 - Primary Preparation
The following are being carried out:
cleaning;
sorting;
measurement;
metal detection;
end processing;
selection of debarking mode;
marking;
creation of a digital passport.
Stage 3 – Primary drying
It takes place under a canopy or in an open pavilion.
Target:
slowly remove free moisture;
avoid overheating;
prevent mold;
reduce the risk of cracks.
Stage 4 – controlled stabilization
The material is moved into a semi-open pavilion.
Controlled by:
temperature;
humidity;
air movement;
warping;
internal stresses.
Stage 5 – final drying
If necessary, apply:
soft convective drying;
dehumidification mode;
vacuum drying;
low temperature chamber;
solar-thermal drying.
High temperature conditions are not a basic requirement for valuable wood.
Stage 6 – Long-term exposure
The fully stabilized material is moved to a dry climate reserve.
8. DREVO Air-Drying Pavilion
The main object of the system is an adjustable semi-open pavilion.
Construction
high opaque roof;
wide overhangs;
protection from lateral precipitation;
adjustable blinds;
open top ventilation area;
raised floor;
drainage;
passages between stacks;
separate sections for breeds;
slow fans;
temperature and humidity sensors;
fire control system;
protection from birds and insects.
9. DREVO Climate Reserve Hall
After drying, the material is moved to a climate-stable storage facility.
Recommended parameters
| Parameter | Operating range |
|---|---|
| Temperature | 10–18 °C |
| Relative humidity | 50–65 % |
| Daily temperature fluctuations | Minimum |
| Daily humidity fluctuations | Preferably no more than 5-10% |
| Air speed | Low and even |
| Lighting | No direct sun |
| Condensate | Not allowed |
| Pests | Constant monitoring |
The main requirement is not the absolute value, butstability of conditions.
10. Correct stacking
Each stack must have:
separate basis;
identical gaskets;
vertically aligned rows of gaskets;
air access from all sides;
batch marking;
inspection passage;
top row protection;
deformation limiters;
the ability to safely remove individual elements.
Gaskets
Typically, the following thicknesses are used for gaskets:
20–30 mm for boards;
30–50 mm for thick workpieces;
individual supports for beams and logs.
11. Drying of round timber
Solid logs require a separate mode.
Key measures:
end protection;
partial debarking;
longitudinal compensation cut for some applications;
slow drying;
protection from direct sunlight;
long exposure;
regular measurement of cracks.
Large trunks with a diameter of more than 80 cm can stabilize for decades.

16. Living Timber Observatory
The monitoring system tracks:
air humidity;
temperature;
wood moisture content;
development of cracks;
warping;
insect activity;
fungal infection;
condition of stacks;
fire risks;
climate history of each sector.
17. WOOD AI Wood
Artificial intelligence analyzes:
drying speed;
risk of cracking;
risk of mold;
optimal position of stacks;
transfer time between stages;
need for final drying;
prospects of use;
probability of transfer to a higher class;
suitable area of application.
18. Pest control
Used:
quarantine of new batches;
visual inspections;
acoustic sensors;
traps;
temperature control;
local heat treatment;
freezing of individual batches;
anoxic treatment;
Permitted safe methods.
It is not recommended to use unless necessary:
toxic impregnations;
residual insecticides;
substances that impair future wood processing.
19. Fire safety
Dry wood is a strategic resource, but it is also a fire hazard.
Required:
division into fire sections;
fire walls;
wide aisles;
smoke and temperature detectors;
Automatic overheat detection;
lightning protection;
limitation of spark-generating work;
separate storage of flammable liquids;
fire water sources;
backup power supply;
Digital map of timber evacuation.
Particularly valuable lots should not be stored in the same building.
20. Territorial distribution
The reserve should not consist of one central warehouse, but of a network.
Network layers
national reserve;
regional reserves;
municipal pavilions;
forestry;
restoration centers;
university collections;
music and art funds.
This reduces the risk of losing all materials in the event of a fire, flood, conflict or technical accident.
21. Reserve rotation
DREVO Air Reserve should not be completely closed.
The rotation principle is applied:
new wood is classified as D-Air or C-Air;
inspected lots are transferred to B-Air;
the best units move to A-Air;
some of the mature wood is used;
new parties are being established in its place;
The entire history is stored in a digital system.

25. The main principle
DREVO Air Reserve preserves wood not until it is sold, but until it reaches its highest value.
The system creates a controlled stock of material that:
properly prepared;
slowly dried;
stabilized;
documented;
protected;
distributed across regions;
preserved for use through decades and centuries.
Together withDREVO Water Reserve, DREVO Timber Reserve, digital passports and the systemWOOD AI WoodThe project forms a full-fledged architecture of the wooden heritage for future generations.
