Size matters:house size and thermal efficiency as policy strategies to reduce net emissions of new developments

摘要: Reducing CO2-e emissions from residential buildings through more stringent building codes has gained increasing international focus. Concurrently, Australian houses have steadily increased in size 1984 to 2009. This paper estimates the capacity of reduce and achieve progressive reduction targets light house sizes. A Residential Emissions Calculator was developed compare heating cooling loads for 72 new houses—based on star ratings, historic sizes by state, The analysis illustrates that significant impact emissions, informs three key results: (1) Victoria is forecast dominate Australia, (2) increase 2003 2009 decreased effectiveness moving 5 stars 6 38%, (3) Progressive 80% could be achieved a variety rating scenarios (with housing affordability impacts). result posit as potent strategies limit energy associated underlines need apply these tandem part integrated national management policy.
