apartment building can be increased by almost 2 %. Figure 13: U value calculation for a non-frame timber wall with a composite thermal insulation system (in comparison with the previous calculation). For almost the same U value the wall is a few centimetres less thick in this case. Excursus The following overview contrasts planning aspects of construction with those of non-frame construction and compares their advantages and disadvantages: Timber-based construction Advantages: Disadvantages: - Temporary carbon storage with favorable - Soundproofing and fire protection impact on the climate balance - Timber protection - Primary energy input to the building is lower - Emission behaviour of timber surfaces, than that of most non-frame constructions particularly wood-based materials - Wider choice of insulation materials for most - In general more elaborate planning required designs - Construction costs are higher for high-quality - Considerable architectural freedom in façade implementation design construction Advantages: Disadvantages: - Cost - Primary energy balance sheet - Soundproofing (heavy building materials) - Choosing insulation materials is harder: - Fire protection polystyrene and mineral fibres are - Practically no emissions from mineral common, renewable or purely mineral construction elements with mineral plaster and insulation materials are possible, but more coating expensive - Heat storage capacity for protection against overheating in summer - Aura of value stability
