建筑活动产生了大量与过程相关的二氧化碳排放，这正在推动木材和轻质材料在快速增长的细长地板中的使用增加。新的可持续地板设计至少可以将体现能量减半，但重量减轻可能会使此类地板更容易受到脚步引起的振动问题的影响。用于解决这一问题的现有技术目前需要结构修改，这是高度破坏性的、昂贵的和不可持续的，或者需要重达数百公斤且效力有限的调谐质量阻尼器，通常需要显著的结构加强以适应额外的质量。我们已经开发出一种全新的振动控制产品，称为CALMFLOOR（r）主动质量阻尼器（AMD）-一种新的和令人兴奋的技术，允许发展的ef？高效率、低成本、环境可持续的建筑，具有良好的振动性能。振动性能在建筑中至关重要。振动会干扰和烦扰建筑物的居住者，也会影响医疗设施、精密制造环境和实验室中敏感设备的性能。AMD是一种自动化设备，可以感知？或振动并产生机械力来抵消它们。它们可以被概念化为"主动降噪耳机？Oors '。他们是Signi？比以前使用的方法更有效。或振动控制，并有可能提供一个解决方案的难题，提供更多的效率？AMD技术将为建筑行业提供急需的竞争优势，因为它是一种先进的技术，可以在建筑性能和效率方面实现飞跃性的变化，从而为建筑行业带来巨大的经济效益。科学。它将增加采用更可持续的结构形式，如约束层木材和模块化建筑。建筑和施工约占全球二氧化碳排放量的40%，因此对环境的影响可能是巨大的。将技术推向市场将产生重大影响。不能新的经济活动，创造工程和制造业的就业机会，并提供一个新的商业优势，英国工程和建筑？通过提供产品测试的增强方案和开发真实的世界实施的案例研究，该项目将有助于将这种新的先进技术推向市场。它将为英国建筑业在世界舞台上提供新的竞争优势，并将进一步发展英国急需的高价值制造业，在公司内部和供应链中提供新的就业机会。

Huge amounts of process-related CO2 emissions are generated by construction activities, which is now driving increased use of timber and lightweight materials in floors of rapidly increasing slenderness. New sustainable floor design can at least halve embodied energy, but reduced weight can render such floors more susceptible to problematic footfall-induced vibrations. The current state-of-the-art for addressing this presently requires structural modifications, which are highly disruptive, costly and unsustainable, or tuned mass dampers weighing hundreds of kilograms and which are of limited effectiveness, often requiring significant structural strengthening to accommodate the additional mass. We have developed a completely new vibration control product called the CALMFLOOR(r) active mass damper (AMD) - a new and exciting technology that allows the development of ef?cient, low cost and environmentally sustainable buildings that have excellent vibration performance.Vibration performance is of crucial importance in buildings. Vibrations can disturb and annoy building occupants and can also affect the performance of sensitive equipment in healthcare facilities, precision manufacturing environments and laboratories. AMDs are autonomous devices that sense ?oor vibrations and generate mechanical forces to cancel them out. They can be conceptualised as 'active noise cancelling headphones for ?oors'. They are signi?cantly more effective than previously used methods of ?oor vibration control and have the potential to provide a solution to the conundrum of providing more ef?cient and sustainable buildings (i.e. with reduced material consumption) whilst still maintaining excellent vibration performance.AMD technology will provide the construction sector with a much-needed competitive advantage as it is an advanced technology that can provide a step-change in building performance and ef?ciency. It will increase the uptake of more sustainable structural forms, such as constrained layer timber and modular construction. Buildings and construction account for approximately 40% of global CO2 emissions so the environmental impact is potentially huge. Bringing the technology to market will generate signi?cant new economic activity, create engineering and manufacturing jobs and provide a new commercial advantage to UK engineering and construction ?rms who adopt it.By providing an enhanced programme of product testing and development of case studies of real world implementation, this project will help to bring this new and advanced technology to market. It will provide the construction industry in the UK with a new competitive advantage on the world stage and will develop further much needed high-value manufacturing in the UK, providing new employment opportunities both within the company and within our supply chain.
