While Lego have their own ‘Digital Designer’ configurator, Brick Link developed ‘.
However, there are four important challenges for the adoption of Passivhaus:.Increased design cost and complexity: It requires specific detailing of the envelope, high quality of construction and specific performance testing in order to get the building certified..
Increased capital cost: The additional construction capital cost can vary from 8% in the most optimistic scenarios (Passivhaus Construction Costs – October 2019) up to 25%..Increased programme: Delivering a Passivhaus building can take longer.Quality control on site is extremely important, strategies for airtightness require careful sequencing and interim testing and workmanship skills need to be of the highest quality..
Skill shortage and understanding.There is a lack of large-scale builders who can deliver Passivhaus buildings.
These projects can be seen as bespoke and are more expensive.. Bryden Wood’ response to Passivhaus’ challenges.
Bryden Wood is an industry leader in the adoption of Platforms-based Design for Manufacture and Assembly (P-DfMA) and has always shown a keen interest in the adoption of the newest and more advanced sustainability certification schemes, such as Passivhaus.. Our experience indicates that the standardisation process of P-DfMA, can be a suitable approach to counterbalance Passivhaus’ challenges described above, as follows:.The construction sector is a major consumer of natural resources, yet the climate crisis demands smarter, more sustainable construction solutions.
To achieve United Nations Sustainable Development Goals we must embrace environmental engineering, by doing everything we can to minimise human impact from the built environment and protect the natural world..There is growing industry consensus that the way we design, build, operate and dispose of our buildings and associated facilities need a major overhaul.
Our aim must be to obviate waste, increase efficiency, reduce greenhouse gas emissions and promote construction methodologies that support both people and the environment..In 2018 the UK generated 222.2 million tonnes of waste, with the construction industry responsible for around 30%.. 1.
