Abstract

Nowadays, we can observe a growing interest in passive buildings due to global climate change, environmental concerns, and growing energy costs. However, developing a passive building is associated with meeting many Passive House requirements, which results in their increased complexity as well as many challenges and risks which could threaten the successful completion of the project. Risk management is a key tool enabling meeting today’s challenging passive house project’s demands connected with quality, costs, deadlines, and legal issues. In this paper, a new model of risk management dedicated for passive buildings based is proposed, in which a novel Fuzzy Fault Tree integrated with risk response matrix was developed. We proposed 171 risk remediation strategies for all 16 recognized risks in passive buildings projects. We show how to apply the proposed model in practice on one passive building example. Thanks to applying the proposed risk management model an effective reduction of the risks of the basic event is enabled, leading to a significant reduction of the top event risk. The proposed model is useful for architects, installation designers, contractors, and owners who are willing to develop attainable and successful passive buildings projects that benefit all stakeholders.

Highlights

A passive house is a construction concept that has become a building standard characterized by true energy efficiency, user comfort, affordability, andcare for ecology at the same time [1]
The European Green Deal’s goals are to radically reduce greenhouse emissions by at least 55% bythe year 2030, hopefully making Europe thefirst climate-neutral continent in the world by 2050 [6]. This goal is in line with the goal of the passive house standard, which focuses on minimizing the energy consumption and carbon footprint of the building, ensuring at the same time high comfort for building users and minimization of additional costs connected with building construction and operation [7]
The first comprehensive risk management model dedicated to passive buildings projects was proposed

Summary

Introduction

A passive house is a construction concept that has become a building standard characterized by true energy efficiency, user comfort, affordability, andcare for ecology at the same time [1]. A growing interest in passive house construction and design is mainly caused by environmental concerns and growing energy costs [5] The popularity of this standard results from the care for the interior microclimate, user comfort, the building’s life cycle, and contribution to active climate protection. The European Green Deal’s goals are to radically reduce greenhouse emissions by at least 55% bythe year 2030, hopefully making Europe thefirst climate-neutral continent in the world by 2050 [6] This goal is in line with the goal of the passive house standard, which focuses on minimizing the energy consumption and carbon footprint of the building, ensuring at the same time high comfort for building users and minimization of additional costs connected with building construction and operation [7]. Thanks to integrating passive houses with renewable energy sources, it is possible to achieve low or zero carbon in a suitable way
