Energy and Cost Analysis

Ünlü Engineering presents different alternatives to their customers to keep the balance between first investment and operational cost.
Ünlü Engineering can simulate the designed buildings with licensed software. Addition to standard heat calculations all mechanical systems that will be used in the building can also be selected by software. Consequently all equipments are selected with correct diversity ratio. This prevents overdesign and minimizes first investment costs.

According to simulation reports, detailed energy analysis is obtained. Energy consumption values and costs are also defined with these reports. Furthermore lifecycle costs can also be calculated for the system alternatives.
