Cost
The expectation of a high up-front cost for a high-performance building is enough to dissuade, even when compared with reduced future running costs
Solution: comparison with similar project types to demonstrate value of additions and scope of savings / efficiencies. Integrate sustainable content into specification, rather than treating as ‘extra over’. Assistance for seeking grants / funding for sustainable works. Retrofitting at scale to create economies.
Awareness
Unsure how to start thinking ‘green’ or best approach for each project, assume project is ‘too small to make a difference’, client lack of experience in building.
Solution: Carbon Literacy engagement, ways to measure quality of environment and value of work, comparison projects, toolbox talks, widespread Retrofit training.
Agency
Intentions of building provider are different to the end user (particularly in housing) creating engagement ‘in principle’ not in use, hard to sell the value of green measures.
Solution: Engage with user where possible, including key stakeholders as project ‘champions’, case study projects that ‘cross over’ cultural barriers. Education about climate change, sustainability and construction across more of the population.
Risk
New construction methods, technologies or retaining existing buildings can carry uncertainty which is unattractive to some clients. Heritage features need to be protected.
Solution: demonstrator projects to explain outcomes, breaking down risks so they don’t ‘snowball’, involve specialist consultants for specific issues, early contractor involvement and inter-project learning / teaching.
