BCO releases new design guidance for greener and healthier offices

Feb 16, 2023 | Public | 0 comments

 

Responding to challenges emerging from the pandemic and the accelerating need for the built environment to respond to climate change, the British Council for Offices (BCO) has released an early update to its Guide to Specification, which provides expert advice on how designers can create healthier offices that support changing working patterns, while reducing carbon emissions.

The BCO Guide to Specification update has been developed in consultation with experts from across the industry, including agents, investors, occupiers, and developers, new recommendations include:

  • Adoption of 10m2 space-per-person
  • Minimum sustainability target of BREEAM ‘Excellent’ and 5 Star NABERS UK target for new buildings
  • Aspirational targets for operational and embodied carbon use to meet NZC (Net Zero Carbon) goals
  • Increased levels of outdoor air supply
  • More efficient lighting installations
  • Reduced power and cooling loads
  • Higher performance facades
  • More flexibility in the range of structural spans for office space

Reflecting the world of hybrid work

The BCO has updated its guidance on space allowed for each employee when designing a speculative office building. 10m2 per person is recommended as the occupancy density design standard for general workspace. The former high occupancy density allowance of 8m2 per person has been redefined as a special use case for exceptional cases. Designing for the 10 m2 per person occupancy density provides greater scope for the variety of workplace settings needed to support hybrid working. It also avoids overdesign of core services, improves floorplate efficiencies, and minimises carbon emissions.

The effect of changing technology

The greater use of low-powered tablets, laptops, and smart phones, plus growth of cloud computing has allowed a reduction in small power load allowances 100 W to 60 W per person. This reduces the heat generated in the office space, which in turn reduces the cooling needed.

Supporting the office sector to achieve net zero carbon

Many developers already target BREEAM ‘Outstanding’ for new offices. Reflecting the rapid progress in the sector in adopting more demanding sustainability targets, the Guide is moving its minimum BREEAM target rating from ‘Very Good’ to ‘Excellent’, and introduces the latest building certification standard, NABERS UK – an energy performance rating relying on measured energy use. The update recommends targeting a 5-star NABERS UK rating for new building design.

Market trends have fuelled a desire to create flexible, relatively column-free, open-plan offices. However, the structural solutions needed can be carbon intensive. The 2023 update to the Guide aids the future adoption of alternative structural materials such as timber by adding smaller 6.0 and 7.5 m spans to the recommended range. This wider range provides designers with more options to minimise the embodied carbon of the structure.

The selection of high-performance facades, lighting and building services systems should also be made with net zero targets in mind, prioritising energy efficiency.

Richard Kauntze, Chief Executive of the BCO, said: “The BCO Guide to Specification often described as the ‘design bible’ for the office sector is an essential resource for the decision makers who invest in, develop or design millions of square feet of office space every year. The 2023 Update will drive the decarbonisation of the office sector, enacting change to help the industry deliver on the UK’s net zero by 2050 target. This new guidance for the highest-quality offices introduces more generous space standards and greater design flexibility to support wellbeing and sustainability as the office sector adapts to the world of hybrid work.”

Neil Pennell, Chair of the BCO’s Technical Affairs Committee and Head of Design Innovation and Property Solutions at Landsec, aded: “The BCO’s new guidance reflects changes in design thinking since 2019 driven by Net Zero Carbon targets, increased hybrid working post COVID-19, changes in regulations and improvements in equipment performance. There is a clear imperative to adopt a whole-building approach to decarbonise the sector which needs to start with the design and specification of new and refurbished office space. Developed in collaboration with the UK’s leading experts, the BCO Guide to Specification gives clear advice on how operational and embodied carbon can be reduced without compromising the need to provide flexible office space that meets the needs of occupiers and helps them to conduct their business in safe, healthy, comfortable and productive workspaces.”


2023 FMJ and Grundon Recycling and Waste Management Survey

FMJ in conjunction with Grundon Waste Management is pleased to launch the 2023 waste management and recycling survey which examines the ways in which FMs approach their waste management responsibilities.

In this, the sixth year for the annual appraisal, we know there is a greater opportunity than ever for FMs to reappraise their waste and recycling operations and help their organisations meet the growing pressure to achieve ESG goals.

We want to learn how FMs have adapted to the legislative, economic and societal changes of the past year and how they plan to meet the latest waste and recycling targets.

In this survey we’ve posed a series of questions which include insights into FMs’ waste management strategy and targets, how they’re moving towards zero waste targets, and the importance of not just meeting compliance targets but also ESG goals.

The results of the 2023 survey will be published in FMJ magazine and form the basis of a white paper co-written by FMJ and the experts at Grundon on how to approach waste and recycling strategies.
