New Study Evaluates Hybrid Heating Systems for Multi-Apartment Buildings
A new paper titled "Analysis of a hybrid heating system with TRNSYS: district heating, heat pumps and photovoltaics in a multi-apartment building" has been published in Energy and Buildings by Elsevier.
The study addresses a research gap in assessing the cost, environmental impact, and performance of hybrid heating systems under real-world conditions. Focusing on a multi-apartment building in Gothenburg, Sweden, the research evaluates a combination of district heating, locally installed heat pumps, and photovoltaics using dynamic simulations in TRNSYS.
Three different control strategies were analyzed, revealing that prioritizing heat pumps significantly reduces both operational costs and greenhouse gas emissions. The findings show that annual energy costs can be cut by more than 50% when heat pumps are the primary heat source, compared to relying solely on district heating.
The research highlights the potential of hybrid systems to improve energy efficiency, lower emissions, and support the integration of renewable energy in residential buildings.
