KoPro Lzk+ - Cost and process optimization in the life cycle of nearly zero energy buildings

The aim of the project is to develop a continuous process chain for the energetic-economic optimization of zero and plus energy buildings. The project will focus on proven and new approaches to cost reduction of nearly zero energy buildings (nZEBs) at all stages of the life cycle. The main goal is to identify the extra-costs for nZEBs, and to promote innovative approaches taking into account the cost-effectiveness for all the Stakeholders. A database containing important cost parameters and potential savings will be developed.

Short Description

Status

ongoing

Starting point / motivation

As research and demonstration projects prove, it is possible to realize cost optimal nearly-zero and plus-energy buildings. While realized buildings have clearly shown that nearly-zero energy targets can be achieved using existing technologies and practices, most experts agree that a broad scale shift towards nearly-zero energy buildings require significant adjustments to prevailing processes and methods in a buildings lifecycle.

The widespread market uptake is expanding very slowly, since methods and processes for the cost-effective integration of efficiency measures and renewable energies are lacking. A broad scale shift towards nearly-zero energy buildings requires additional methodical approaches and processes trough all stages of the project life cycle.

Contents and goals

The project will focus on proven and new approaches for the cost reduction of nearly zero energy buildings enabling a continuous energetic-economic optimization of highly efficient buildings in all planning phases.

Methods

The main goal is to identify the extra-costs for nZEBs and to promote innovative approaches taking into account the cost-effectiveness for all the Stakeholders. Based on realized zero and plus energy buildings relevant cost parameters are collected and quantified and will result in benchmarks and idealized processes. The goal is to develop a continuous methodological approach with the aim of an improved cost efficiency which will be applicable to the all phases of a buildings life cycle - from the urban scale to the individual building and its operation.

Expected results

Expected results are a study and an interactive planning catalog with the following structure:

  • Processes for energetic-economic optimization of zero and plus energy buildings in all planning phases
  • Definition and quantification the cost-saving potentials throughout the life cycle of nZEBs
  • Database with cost parameters and potential savings of nZEBs
