Construction industry

Construction sector occupies a unique position in society. It shapes where we live and work, contributes to GDP and is a major employer. The importance of sustainable economic, social and environmental development is now firmly at the top of the agenda for many in the industry. Sustainability is at the heart of the future of construction including supply chain, skills development, innovation, long term planning and productivity.

The opportunity

Hybrid technology offers significant benefits to the construction sector to achieve these major objectives. Combining innovative products with smart data enables contractors to not only deliver the needs for improved environmental performance, but also to report these findings as part of wider regulatory requirements such as ESOS (Energy Savings Opportunity Scheme).

Our role

The construction industry is responding to the challenges associated with the reduction of emissions, not only with operation of the final product, but also managing emissions during the building phase.

Firefly has worked closely with the plant hire and construction sector to develop a range of robust, rental specification hybrid power solutions that meet the needs of this changing industry.

In addition, Firefly team is always on hand to help with:

  • Site power requirement audits

  • Specification support

  • Equipment training

  • Real time reporting of fuel and CO2 savings

  • Track, control and manage hybrids from any internet enabled device

  • Technical support

Benefits of using hybrid power in construction

  • Efficient and silent power supply on site

  • Reduction of CO2, NOx and PM emissions

  • Significant reduction of fuel costs

  • Production of easy to read environmental reports for all sites
