b'TopicsTopic RequirementsOverall design - Avoid new construction- Increase building utilisation- Design for longevity- Design for adaptability- Design for disassemblyEnergy - Use energy-efficient building systems (i.e. lighting systems with occupancy and lux-sensors)- Use renewable energy sources (i.e. solar and wind energy)- Use a compact building volume and efficient use of glazing for reduced energy loss- Optimize building orientation towards south (northern hemisphere) to capture longer periods of daylight- Consider of placement of glazed areas, to reduce solar gains in summer, increase in winter- Use a building construction with a high thermal value that helps to passively cool and heat, reducing the need for technical installationsWater - Use water-saving toilets and taps- Provide leak detection- Use systems that allow water re-use and recycling- Use water in outdoor areas (close to building), to improve the microclimatic comfort during summer- On-site rainwater through preservation of areas of ecological value and/or the use of absorbing surfaces like grass and plantsMaterials - Use materials with low embodied energy (materials that do not overly pollute during manufacture)- Use waste materials or material with a high percentage of recycled content in construction.- Avoid the use of fragile materials that require frequent maintenance - Use materials with hygroscopic value (materials that regulate and improve indoor comfort)- Use certified materials. Ask for EPDs (environmental product declarations) to understand where products come fromWaste - Create environmental stations throughout the building to sort recyclables and dispose of waste- Require waste management during construction to limit the impact on the environment.- Provide facilities for composting organic wasteSustainability requirementsThis is a general checklist of sustainability topics. More specific requirements can be based on rating systems like BREEAM and LEED or practical guidelines such as ARUPs Circular Buildings Toolkit.114'
