 (3) In case of construction of a building with climate control or its major renovation works, the recommendations of the design undertaking are presented regarding the energy performance to use the technological systems with high energy performance (e.g heat pump, decentralized energy supply system based on energy produced from renewable energy sources, combined heat and power system, district and local heating or cooling system, specially when it is fully or partially based on energy produced from renewable energy sources), if this can be performed technologically, functionally and economically.

Chapter 4 SPECIAL REQUIREMENTS FOR DIFFERENT BUILDING DESIGN DOCUMENTATIONS 

§ 27.  Building design documentation for demolition of the building

 (1) Building design documentation prepared for partial or full demolition of construction work may be based on a basic geodetic plan, terms of reference of the customer, description of the current situation, positions of interested persons. In addition to the provisions of section 19 of the Building Act, building design documentation prepared for demolition of construction work may also be based on technical specifications of possessors of the utility system, design specifications or orders or precepts of the local government or the Technical Surveillance Authority.

 (2) The purpose of building design documentation prepared for the demolition of construction work is to provide information to the performer of demolition work on the construction work or a part of it to be demolished, instructions for the safe conduction of demolition works and recycling and utilisation of demolition waste, and to provide information to the local government on the extent of demolition activities to be able to assess the impact of the demolition and issue a permit for the full or partial demolition of construction work.

 (3) Building design documentation prepared for the demolition of construction work shall include instructions and solutions for the performance of the works with the degree of accuracy (stage) which enables the contractor to complete the works in a safe and environment-friendly manner according to the building design documentation and using trained and experienced labour under the supervision of competent engineering and technical staff.

 (4) Minimum of the following must be contained in the building design documentation at application of the building permit:
 1) description of the parts of the construction work to be demolished;
 2) requirements and methods for and extent of protection of utility networks, buildings and construction works, green areas and other elements to be preserved;
 3) rechnological description of demolition works, sequence of demolition and safe techniques for the performance of the works;
 4) conditions and locations for the disconnection of utility networks;
 5) if appropriate, methods and locations for the disconnection of elements;
 6) if appropriate, methods for temporary supporting of parts of construction work;
 7) mapping of hazardous materials contained in the construction work, their presumed types and quantities and requirements for their safe collection and handling by different types;
 8) approximate quantities of the materials and products obtained, possible sites for their recycling and disposal, gathering and handling by different types of wastes.

 (5) methods for protection, disconnection or liquidation of utility networks are determined in the building design documentation for demolition of the building. Methods of disconnection or liquidation of the utility networks are coordinated with the owner or possessor of relevant utility network.

 (6) if needed, the building works organisation plan is prepared for demolition of the building in addition to the building design documentation.

 (7) The building design documentation for demolition of the building is provided in most common scales.

 (8) In the case of partial demolition of construction work, building design documentation prepared for the erection of construction work may also contain building design documentation for the demolition of construction work. If relocation of utility networks or any other important building work is required for the performance of demolition works, independent building design documentation shall be prepared therefor.

§ 28.  Implementing provisions

 (1) [Omitted from this text.]

 (2) Building design documentation for construction work, presented for application for a building permit before 1 January 2011, shall be deemed as conforming to the requirements also if it meets the requirements for building design documentation that were effective at the time of its preparation for application for a building permit.
