For designers proceeding with work in accordance with nZEB, management strategy means that participants of different disciplines have to accept that surrounding environment parameters are in constant interaction with design. This further points out the necessity to understand the correlations taking place between local and existing environments, when buildings should be fitted out with systems working in interaction between the local and general biosphere parameters. Hence, within the construction business, such development means integrated proceedings in all design phases and construction sphere itself, integration of the artificial systems allowing for the buildings function and parameters characteristic to the local surroundings. This condition also applies to nZEB buildings, except that the parameters are more limited to passive and active solutions used for achieving effective energy choices, while maintaining required user comfort parameters and environmental balance. This chapter is dedicated to management procedures for nZEB investments from a Polish perspective.

Integrated Design Procedures

The secondary effects of stricter design process and more energy demanding construction laws are lower design fees and construction costs paid by the investors. This also has direct influence on a better market situation of manufacturers of environmentally friendly building materials and technical systems. What is more, contractors also have better tools to build buildings where these solutions have been introduced. Research proves that additional cost should not exceed 12.5% of total costs (The Business Case for Green Building, 2013), even in case of nearly zero energy buildings (nZEB). In case of those buildings, effective costs measures may include, but not be limited to:
