Abstract [en]

Energy efficiency is a cornerstone of climate change mitigation. For buildings, facility management is an essential part of achieving efficient energy use while keeping tenants satisfied. This interview study explores success factors and barriers for facility management in maintaining energy efficiency over time in four approximately 10-year-old non-residential premises built as so-called nearly zero-energy buildings (nZEB) in Sweden. The study highlights the importance of functional digital tools, benchmarks, and building professionals’ involvement in ensuring energy efficiency. It also emphasizes the need for involvement communication and strategies to engage facility management in energy efficiency efforts. The study suggests that in-house and public policies can play a crucial role in sustaining high ambitions for energy efficiency. Access to professional support that is self-evident to use is identified as a critical success factor. Additionally, the research presents an analytic model that can be used in future studies to assess facility management organizations’ potential for maintaining energy performance in buildings over time.

Abstract [en]

One step towards reducing greenhouse gas emissions is to use energy in a more efficient way and increase the share of renewable energy. This thesis focuses on the construction process and operation of non-residential buildings. The “housing and service” sector, which includes non-residential buildings, accounts for just over one-third of final energy use in Sweden. Reaching energy performance requirements and maintaining them over time is important. Through a socio-technical perspective, I have investigated how different roles and processes involving professional stakeholders affect efficient energy use in non-residential buildings. Interviews and surveys were the main research methods. When energy production and energy use do not coincide in time, there is need for energy storage, for example with batteries. Furthermore, digitalization in the ongoing twin transition may provide better and more energy efficient control of buildings. Therefore, barriers and drivers for investments in battery storage and building automation have been examined in this thesis. Knowledge is an important factor throughout the construction process and operation to achieve and maintain energy performance. The thesis contributes a method and analysis model to support the actors in the construction process to create clear goals and achieve them. Formulating and following up energy requirements is central during both the construction and operation phases of buildings. The thesis shows the importance of identifying causes of deviations and dealing with them. Functioning digital systems are a prerequisite but not a replacement for on-site operating personnel to maintain low energy consumption over time. Two-way communication within and between actors is important, both during the construction process and the operational phase. It is also important with functioning external support when the technology does not work, and that it is obvious in the organization's culture to use the support.

Abstract [sv]

Ett steg på vägen för att minska utsläppen av växthusgaser är att använda energi på ett mer effektivt sätt och öka andelen förnyelsebar energiproduktion. Avhandling fokuserar på byggprocessen och fastighetsdrift för lokalfastigheter. Sektorn ”bostäder och service” där lokalfastigheter ingår står för en dryg tredjedel av den slutliga energianvändningen i Sverige. Att nå energiprestandakraven och bibehålla dem över tid är viktigt. Genom ett sociotekniskt perspektiv har det undersökts hur olika roller och processer som involverar professionella intressenter påverkar effektiv energianvändning i lokalbyggnader. Intervjuer och enkäter har främst använts som forskningsmetoder. När energiproduktion och energianvändning inte sammanfaller i tid skapas behov av energilagring, med tex batterier. Den digitala utvecklingen ger möjligheter att bättre kunna styra och optimera byggnader och kapa effekttoppar. Därför har hinder och drivkrafter för investeringar i batterilager och fastighetsautomation undersökts närmare i denna avhandling. Kunskap är en viktig faktor genom hela byggprocessen och förvaltningen. Genom kunskap ökar möjligheterna att uppnå och bibehålla energieffektiv drift över tid. Avhandlingen bidrar med en metod och analysmodell som kan användas som stöd av aktörerna i byggprocessen för att skapa tydliga mål och nå dem. Att formulera och följa upp energikrav är centralt både under bygg- och förvaltningsskedet för byggnader. I avhandlingen visas på vikten av att identifiera orsaker till avvikelser och hantera dem. Fungerande digitala system är en förutsättning men ingen ersättning för driftpersonal på plats för att bibehålla låg energianvändning över tid. Tvåvägskommunikation inom och mellan aktörer är viktigt både under byggprocessen och driftskedet. Det är också viktigt med fungerande externt stöd när tekniken inte fungerar samt att det i organisationens kultur är självklart använda det stödet.
