Depreciation

Similar to real world assets, factories and buildings inside the NAKAVERSE also go through stages of asset depreciation. The depreciation is coded into each building and building will depreciate only when being utilized. Depreciation will lower down the utilization rate of the building (mining raw materials, crafting items, producing food and energy), which will continuously depreciate until the factory / building is no longer functional.

Depreciation Rate

Building Depreciation	Days	Factory Mining Rate
0%	Day 1 - Day 7	8000 / day
-10%	Day 8 - Day 14	7200 / day
-20%	Day 15 - Day 21	6400 / day
-30%	Day 22 - Day 28	5600 / day
-40%	Day 29 - Day 35	4800 / day
-50%	Day 36 - Day 42	4000 / day
-60%	Day 43 - Day 49	3200 / day
-70%	Day 50 - Day 56	2400 / day
-80%	Day 57 - Day 63	1600 / day
-90%	Day 64 - Day 70	800 / day
-100%	Day 70+	No Yield

The depreciation level increases as the buildings has been utilized without performing any maintenances, while at the same time lowers down the mining yields per day. The higher the depreciation, the lower the yields.

However, although your factory is utilizing at a lower yield, the amount of resources used remains the same. For example, if your mining factory is under 20% depreciation, you will receive only 6400 raw materials per day, but it will mine 8000 worth of raw materials from the land each day, resulting in a loss of 1600 raw materials to depreciation rate.

Building Maintenances

In order to avoid asset depreciation, each factory and buildings will require building maintenances to fix the building from depreciating even further and return the building to 100% factory quality. These maintenances fixes will require various resources created within the NAKAVERSE, and each building will require different types of resources, usually in forms of INGOTS (Copper Ingot / Iron Ingot / Oil / Processed Coal, etc.)

Factory / Building	Repair Resource	Primary Resource	Secondary Resource
Copper Mine	Copper + Wood	Copper (75%)	Wood (25%)
Iron Mine	Iron + Wood	Iron (75%)	Wood (25%)
Sawmill	Wood + Iron	Wood (75%)	Iron (25%)
Gem Mine	Gem + Wood	Gem (75%)	Wood (25%)
Oil Refinery	Oil + Wood	Oil (75%)	Wood (25%)
Coal Mine	Coal + Wood	Coal (75%)	Wood (25%)

The resources that will be required to do the maintenance fix comprises of two materials, the primary resource and the secondary resource.

The primary resource, usually the same materials that is the yield of the factory, will be the main resource that will cover 75% of the total costs of the maintenance.

The main secondary resources for all the mining factories are Woods, mined through Woodland using Sawmill, will cover the rest 25% of the total costs of the maintenance (except for Sawmill itself which uses Iron as secondary resources.

Maintenance Costs

To understand how much resources will be required to perform maintenance at each building depreciation level, please use the following guideline:

The depreciation cost will accumulate every day, starting at 200 resources / day and will increase in value beyond factory quality 80% by 10 resources for every 10% factory quality losses.

Although the depreciation is happening at factory quality = 100%, you cannot perform maintenance on your factory just yet. You may only start your building maintenance once the factory quality level is at 90% or under.
