22 R F & O - s u s t a i n a b i l i t y b r i e f The Sustainability Brief is completed at RIBA Stage 2 and sets out the project s sustainability strategy, targets and constraints. 1. Client requirements e.g. internal environmental conditions required 2. Sustainability objectives and targets including target BREEAM rating, business objectives etc. 3. Timescales and budget 4. List of consultees and professional appointments that may be required e.g. Suitably Qualified Acoustician etc. 5. Constraints for the project e.g. technical, legal, physical, environmental

23 P a s s i v e d e s i g n a p p r a i s a l A Passive Design Analysis (PDA) is carried out during Concept Design stage (RIBA Stage 2) which identifies opportunities for the implementation of passive design solutions that reduce demands for energy consuming building services. 1. PDA should cover the following as a minimum: Site location Site weather Microclimate Building layout Building orientation Building form Building fabric Thermal mass or other fabric thermal storage Building occupancy type Daylighting strategy Ventilation strategy Adaption to climate change 2. The building uses passive design measures to reduce the total heating, cooling, mechanical ventilation, lighting loads and energy consumption in line with the PDA which demonstrates a >5% reduction in total energy demand as a result.

24 C l i m a t e c h a n g e a d a p t a t i o n s t r a t e g y a p p r a i s a l The Climate Change Adaptation Strategy Appraisal is prepared for structural and fabric resilience by the end of Concept Design (RIBA Stage 2). The Appraisal contain a systematic (structural & fabric resilience) risk assessment and will cover the following: a. Identify/evaluate the impact on the building over its projected life cycle from expected extreme weather conditions arising from climate change. b. Will, where feasible, mitigate against these impacts. c. Will cover: Hazard identification; Hazard assessment; Risk estimation; Risk evaluation & risk management. Identify risk presented by hazard for the following elements: a. Structural stability & robustness b. Weather proofing and detailing c. Material durability d. Health and safety of building occupants and others e. Impacts on building contents and business continuity

25 P r e r e f u r b i s h m e n t a u d i t A pre-refurbishment audit of all existing buildings, structures or hard surfaces within the scope of the refurbishment or fit-out zone.(carried out at RIBA Stage 2) 1. Results guide the design, identify materials that can be reused, set targets for waste management and ensure contractors maximise high grade reuse/ recycling opportunities. 2. It is carried out by a competent independent person with appropriate knowledge of buildings, waste and options for the reuse and recycling of different waste streams 3. Actual waste arisings and waste management routes are compared with those forecast from the audit and barriers to achieving targets should are investigated 4. Identify and quantify the key materials present on the project. 5. Identify potential applications and any related issues for the reuse and recycling of the key materials in accordance with the waste hierarchy. 6. Identify local re-processors or recyclers for recycling of materials 7. Identify overall recycling rate for all key materials 8. Identify reuse targets where appropriate. 9. Identify of overall landfill diversion rate for all key materials

26 B u i l d i n g f u n c t i o n a l a d a p t a t i o n s t u d y A building-specific functional adaptation strategy study is undertaken by the client and design team at RIBA Stage 2. It should include recommendations for measures to be incorporated to facilitate future adaptation. The study should consider and confirm the following: 1. Potential for major refurbishment, including replacing the facade. 2. Design aspects that facilitate the replacement of all major plant within the life of the building e.g. panels in floors / walls that can be removed without affecting the structure, providing lifting beams and hoists. 3. Adaptability of the internal physical space and external shell for change in use. 4. The extent of accessibility to local services, eg local power, data infrastructure etc. 5. Feasibility for multiple/alternative building uses/ area functions related to structural design. 6. Routes/ methods for major plant replacement e.g. extension of networks/ connections. 7. Options for multiple uses & area functions based on design details e.g. modularity. 8. Accessibility for local plant and service distribution conduits and connections. 9. The potential for the building to be extended, horizontally and/or vertically. 10. Functional adaptation measures/recommendations should be implemented by RIBA Stage 4 where practical and cost effective. Omissions have to be justified in writing.

30 C l i m a t e c h a n g e a d a p t a b i l i t y r e p o r t The Climate Change Adaptability Report builds on the thermal model used to demonstrate compliance with CIBSE Guide A, but looks at how the building will perform against future predicted climatic conditions. Credit criteria: 1. Run a thermal model to demonstrate the temperature range requirements of CIBSE Guide A for the building against a projected climate change environment in line with industry standard weather data for the UK Test Reference Years (TRYs) and Design Summer Years (DSYs) provided by CIBSE. 2. Where the building does not meet thermal comfort levels for projected climate change, the project team must demonstrate how the building has been adapted, or designed to be easily adapted in future using passive design solutions in order to subsequently meet the requirements.
