VOS Group has been engaged to incorporate complete audio/visual systems within corporate boardrooms including teleconferencing, videoconferencing, concert theatre, boardroom and stadium venues.


At VOS Group, we define ecologically sustainable development as the use of resources in a manner that does not compromise the ability of future generations to use those resources. VOS Group strives to meet this objective by designing sites that minimise the demand for resources such as water, energy and materials providing innovative alternative supply through water reuse and on-site generation of power. VOS Group engineers work closely with clients to identify solutions to achieve the most sustainable and cost effective outcome for every site. Each member of VOS Sustainability is a qualified engineer; this ensures sound design with excellent linkage to the ESD objectives of clients and other building services.

Team members are accredited under Green Star, NABERS and the CBD Scheme; all services are certified under the ISO 9000 Quality Assurance System. The VOS Sustainability is complemented by VOS Group’s in-house expertise in Mechanical, Electrical, Hydraulic, Fire, Vertical Transportation, Lighting, Communication and Audio Visual Engineering. Each site offers unique opportunities for resource sustainability and our engineers identify these opportunities at the earliest project stage, working in close consultation with clients.

VOS Group’s design solutions provide sustainable energy, water and resource consumption.  They are innovative without compromising building performance and are also cost-effective in terms of initial capital cost, ongoing operations and maintenance expenditure. International best practice is the minimum benchmark for every project undertaken, with VOS Group committed to being leaders in the constantly evolving field of ecologically sustainable development. In every project undertaken, VOS Group engineers aim to identify design solutions that will maximise energy supply efficiency and minimise on-site energy demand, exceeding regulatory benchmarks and industry best practice.

VOS Group engineers apply the principles of ‘passive’ design strategy, such as natural ventilation and day lighting, with considered application of ‘active’ technologies such as efficient mechanical, hydraulic and lighting system components. VOS Group engineers draw upon the knowledge and expertise of all building services disciplines within VOS Group to ensure all opportunities for energy efficiency are achieved, for each project.
