Change in heating costs for different renovation alternatives of a million-housing program building
In 2014 the network for energy efficient multi-residential buildings, BeBo, finished a project called “Ett hus, fem möjligheter” (“One building, five opportunities”). The purpose was to provide insight into and a comparison of five different renovation alternatives for an existing building from the million-housing program, resulting in a decrease in energy use by at least half. Since the completion of this project the district heating tariffs have undergone deeper differentiation and added complexity, with several price components that make up the total DH (district heating) price, such as power price, energy price and return temperature discount or fee. Meanwhile, average electricity prices in Sweden have increased. The impacts of these price developments on the energy cost savings of the five alternatives in “Ett hus, fem möjligheter” have not been investigated. Due to this, the consultant company WSP, which is tasked with coordinating BeBo, requested an investigation on what change there has been in heating costs for the renovation alternatives from “Ett hus, fem möjligheter” between 2014 and 2019 in the city of Stockholm, with focus on Stockholm and Solna municipality. Energy demand for the building and its alternatives was simulated and entered into an energy cost calculation tool called PRISMO developed by BeBo in 2017, together with energy price structures for Stockholm municipality (from Stockholm Exergi for DH and from Ellevio for electricity) and Solna municipality (from Norrenergi for DH and from Vattenfall Eldistribution AB for electricity). The results showed a change in energy cost for all alternatives in all scenarios. In Stockholm municipality, both district heating and electricity cost has increased for all alternatives. DH cost has increased by between 15% and 18% for the base building and all alternatives using only DH (alternatives 1 and 2). In alternatives with combined DH and electricity the DH cost has increased by about 24% where DH is used for domestic hot water and peak heat load, and ...
