Abstract
Dette speciale undersøger, hvordan energiefterspørgslen kan reduceres, og hvordan mere bæredygtige varmeanlæg kan integreres i individuelle danske bygninger, med udgangspunkt i et modelleret enfamiliehus. Formålet er at forbedre bygningens energiydelse ved at reducere energibehov, brændselsforbrug og CO2-udledninger. Arbejdet er opdelt i en teknisk-økonomisk del og en institutionel/politikanalyse. På efterspørgselssiden modelleres tre isoleringsscenarier, mens udbudssiden vurderer udskiftning af en eksisterende oliekedel (referencescenarie) med tre alternativer: luft-til-vand-varmepumpe, jordvarmepumpe (ground source heat pump) og fliskedel. Modelleringen gennemføres i COMPOSE, og resultaterne vurderes med hensyn til energi, omkostninger og emissioner. Desuden vurderes gældende politikker og reguleringer samt markeds- og finansielle barrierer, og muligheder for implementering af den eller de optimale løsninger diskuteres. Den udleverede tekst indeholder ikke specifikke kvantitative resultater; specialet sammenligner dog scenarierne og skitserer forudsætninger for gennemførelse.
This thesis examines how to reduce energy demand and integrate more sustainable heating systems in individual Danish buildings, using a modelled single-family house as the case. The aim is to improve building energy performance by lowering energy use, fuel consumption, and CO2 emissions. The work is divided into a techno-economic analysis and an institutional/policy assessment. On the demand side, three insulation scenarios are modelled; on the supply side, the replacement of an existing oil boiler (reference) is evaluated against three alternatives: an air-to-water heat pump, a ground source heat pump, and a wood chips boiler. Modelling is carried out in COMPOSE, and outcomes are assessed in terms of energy, costs, and emissions. Current policies and regulations are reviewed alongside market and financial barriers, and the implementation of the optimal solution(s) is discussed from economic and institutional perspectives. Specific quantitative findings are not included in the provided excerpt; the thesis compares the scenarios and outlines conditions for implementation.
