A Guide to Sustainable Windows and Doors to Achieve RIBA’s Sustainable OutcomesRIBA-Approved CPD by Freedom BespokeWindows and doors are often seen as one of the most challenging elements of a building project—balancing design, performance, regulation, and sustainability. This RIBA-approved CPD provides architects with the knowledge and tools to specify glazing systems that not only meet design aspirations but also deliver on the RIBA Sustainable Outcomes and the UN Sustainable Development Goals.This seminar is designed to help architects and specifiers navigate the complexity of sustainable window and door design, from material choice and performance standards to installation detailing and lifecycle impact.What You Will LearnThe CPD addresses sustainability through both operational performance (energy efficiency, airtightness, thermal bridging) and embodied carbon (material sourcing, manufacturing, end-of-life recyclability). Architects will gain practical insight into how window and door specification influences building outcomes across the full lifecycle.Key topics include:RIBA Sustainable OutcomesAlignment with the RIBA Sustainable Outcomes GuideHow glazing design contributes to Net Zero, social value, and wellbeingOperational Carbon and Energy PerformanceThe fabric-first approach to reduce energy demand before adding systemsOptimising airtightness, solar gain control, and natural ventilationThe importance of correct installation detailing (thermal bridging, Ψ-values, airtightness strategies)Embodied Carbon and MaterialsComparative assessment of uPVC, aluminium, timber, and composite framesUse of Environmental Product Declarations (EPDs) and whole-life carbon analysis (example study)Responsible sourcing, including FSC-certified timber and recycled aluminiumDesign for disassembly and the circular economyRetrofit vs. New BuildWhy “the greenest building is the one that already exists” (Carl Elefante)Relevant standards such as PAS 2035:2023 and EnerPHitBalancing performance upgrades with heritage and aesthetic considerationsHealth, Wellbeing, and ComfortDaylighting and glare controlIndoor air quality and ventilation strategies (MVHR vs. trickle vents)Acoustic comfort—performance comparison of double and triple glazingInclusive design: accessibility, usability, and lifetime occupationRegulations and StandardsUK Building Regulations Part L (Conservation of Fuel and Power) and Part E (Acoustics)Future Homes StandardBiodiversity and Social ValueDesigning glazing and accessories to minimise light pollutionMeeting requirements for 10% biodiversity net gain in major projectsCreating healthy, inclusive spaces that enhance community valueWhy This CPD MattersAround 30% of UK carbon emissions come from buildings, with homes responsible for 35% of all energy use (UKGBC).19 million UK homes have an EPC rating below C, highlighting the urgent need for deep retrofit.Choosing the wrong window or door system can compromise performance, increase operational carbon, and add long-term costs.Correct specification can improve energy efficiency, reduce embodied carbon, support occupant wellbeing, and future-proof designs against climate change.Who Should Attend?Architects and specifiers working on residential or mixed-use projectsPractices seeking to strengthen their sustainability credentialsProfessionals engaged in retrofit, Passivhaus, or Net Zero projectsAnyone aiming to deliver projects aligned with RIBA 2030 Climate Challenge targetsOutcomesBy the end of this CPD, participants will be able to:Identify how windows and doors directly impact RIBA Sustainable OutcomesMake informed choices between materials based on whole-life carbon and performanceApply fabric-first principles to achieve Net Zero operational carbonSpecify products that enhance wellbeing, resilience, and social valueNavigate evolving regulations and sustainability standards with confidenceBook a SessionThe CPD is available through the NBS Partner Platform and can be booked directly by RIBA Chartered Practices and architects.For more information or to arrange a seminar, visit Freedom Bespoke.
