Effective and efficient data collection in designer workflows for environmental certifications in building design

Abstract

This thesis investigates how environmental certification systems—specifically BREEAM, LEED, and RTS—affect the mechanical, electrical, and plumbing (MEP) design process, with a particular focus on the effectiveness of certification requirements and the efficiency of data collection. The research was conducted in collaboration with the Granlund company and LUT University and combines qualitative methods, including three expert interviews, project document analysis, and participation in a certification-focused industry workshop.

The study explores three core research questions: how information collection related to certifications can be organized efficiently; how certification requirements can be integrated to support effective design and implementation; and how designers can minimize repetitive investigative work and share learning across projects. Findings highlight that while international systems like BREEAM and LEED are comprehensive, they often present usability challenges due to fragmented evidence requirements, unclear responsibilities, and limited compatibility with Finnish design practices. In contrast, the RTS certification system offers clearer requirements, stronger alignment with local design documentation, and a more efficient evidence collection process.

The thesis concludes with targeted recommendations for design firms, certification coordinators, and system developers. These include improving early-phase planning, developing internal evidence templates, and enhancing knowledge transfer between projects. Overall, the research emphasizes that environmental certification can support sustainable building goals more effectively when integrated into design workflows, aligned with local practices, and supported by structured organizational learning.
