Environmental issues such as climate change have become a major concern over the last decade as the scientific evidence has been increasingly alarming over the global warming and its impacts on the environment, society and the economy.
The UK Climate Change Act adopted in 2008 establishes a target of at least 80% reduction in greenhouse gas emissions by the year 2050 in comparison to the 1990 baseline. All sectors will need to contribute to reducing global warming, including the construction sector. RPC Limited have developed the RoofWright tool for designing conservatories and as part of the continuing development of this tool have asked TRL to examine the potential for carbon modelling to be introduced to the future versions of this programme.
TRL have undertaken a desktop review of the parameters that need to be considered when integrating carbon modelling into conservatory design. The review covered the existing relevant building regulations, research literature and existing building and construction technologies and methodologies on the subject. As a result, a range of parameters were identified to be considered for inclusion in the improved version of the company’s software. These were further organised into three groups, namely, technical parameters (those currently regulated by the existing building regulations), design features (those chosen on an individual basis), and geographical and environmental aspects (those covering, e.g. specifics of location and orientation). Based on these findings, recommendations were made for the ways to improve energy performance of conservatories through incorporating energy/carbon calculations into the conservatory design software.
