Q

What are BREEAM credits?

A
  • An asset score awarded for an assessment issue when a benchmark is reached, determined by a BREEAM assessor
  • Assessment issues are sub-divisions of BREEAM categories
  • Category score is calculated according to number of credits achieved and its category weighting
  • Once development fully assessed, the final performance rating is determined by the sum of the weighted category scores

Q

What are the different BREEAM credit categories?

A
  • Management: adoption of sustainable management practices in connection to design, construction, commissioning, handover and aftercare
  • Heath and wellbeing: encourages increased comfort and H&S of occupants and visitors
  • Energy: design of energy efficient building solutions, systems and equipment that support the sustainable use of energy in the building and sustainable management in the building’s operation
  • Water: sustainable use of water in the operation of the building, identify reducing potable water consumption and minimising losses through leakage
  • Materials: responsible sourcing of materials, low embodied impact
  • Transport: access to sustainable means of transport such as public transport or alternatives means of reducing car journeys
  • Pollution: prevention and control of pollution and surface water run-off; reduce impact of light, noise, flooring and air pollution
  • Land use: habitat protection and creation, improvement of long-term biodiversity; use of brownfield sites, or mitigation and enhancement of ecology
  • Waste: sustainable management of waste through construction, operation and future maintenance
  • Innovation (additional 10% credits) - exemplary performance not within or go beyond other credits
