Aesthetics vs. Efficiency? Balancing Energy Performance and Architectural Appeal through Decision Support with Telegram Bot

Abstract

Balancing energy performance and architectural appeal in building renovation presents significant challenges, especially with regulations like the Buildings Energy Act (GEG) emphasizing energy efficiency. This study investigates which retrofit measures have the greatest impact on aesthetics. Through stakeholder analysis, the study examines the interests of key groups involved in renovation projects, including property owners, architects and engineers. To identify potential conflicts between energy efficiency and aesthetic quality, thirteen expert interviews were conducted. Based on these findings, a Telegram Bot is proposed as a decision-support tool. In a case study, the bot demonstrates how it can provide tailored recommendations to balance energy performance and architectural appeal, thereby strengthening the life cycle approach of buildings.
