These finalists have shown the best contributions to low-carbon and sustainable construction in the past 12 months. Judges were looking for leading sustainability, innovation, whole-company commitment and examples of winning work through a low-carbon approach.
In the past 12 months, 100 per cent of B&K Structures’ projects used sustainable timber as the primary structural constituent – a material that the company has consciously shifted to in the past six years.
The firm has also developed a carbon calculator to help clients understand which of their options will generate the optimum low-carbon solution by taking into account transport, factory waste, factory emissions and waste removal as well as the construction methods and materials used.

BCM’s team of design engineers works with construction companies across the UK to ensure built environment designs are as low-carbon and energy-efficient as possible.
The firm has developed its own design process using dynamic simulation modelling software, linking with internal BIM processes, to feed information into the overall lifecycle analysis of a building – ensuring the team’s design can progress with certainty to set low-carbon parameters.
As a purchaser of a significant amount of construction plant equipment, GAP Group only buys tools and machinery that meet or exceed current environmental standards.
For example, it is trialling prototype machines from Terex that exceed Stage 4 emissions standards a year ahead of their mandatory adoption. It also launched its Green Action Plan, a strategy to reduce its impact on the environment.
New lighting systems and rainwater harvesting tanks at depots have contributed to big savings on the company’s water and electricity consumption.
NG Bailey’s five-year sustainability campaign, Target 2012, came to a close last year. The campaign had four objectives: to reduce carbon emissions by 20 per cent; to half the amount of waste sent to landfill; to cut water use by 20 per cent; and to use more materials from sustainable sources.
All of the targets were exceeded as the company reduced CO2 emissions by 34 per cent and water use by 27 per cent, and ensured 72 per cent of all waste was recycled. A new five-year strategy, One Approach, has now been launched to build on these achievements.
S and B Eps
Family-owned S and B Eps launched a new product last year: Lambdatherm, a grey expanded polystyrene product with low thermal values. Made from BASF, this BREEAM-approved product is 98 per cent air and is fully recyclable.
To complement this, the company introduced a waste collection scheme for external wall insulation applicators.
When Lambdatherm boards are delivered to site, offcuts of clean waste are collected and recycled to make new Lambdatherm panels – more than 3,000 cu m of EPS was recycled back into Lambdatherm from January to September 2013.
