The project is organised in four main work streams divided into various tasks as shown below.

Leading organisation for each work stream and task is shown in brackets. WS stands for work-stream. The work streams are as following:

WS-A: Data Collection/Creation [METU]

TA-1 [METU, UCL, KOR-DER, STBA, UKCMB]: Field surveys, which will comprise the case study locations to cover all local climate regions in Turkey based on TS825 (2008) and diverse building types in these. Up to 5 archetypal buildings will be chosen based on building authenticity and indications of damage, and surveyed for geometry, construction system, materials, primary agents of deterioration and moisture risk by using non-destructive methods and risk assessment techniques specified in BS5250 (2011), BSI/UK/899/ST/0816/EN/HL (2017) and other UKCMB guidance.

TA-2 [UKCMB, METU, UCL]: Temperature-humidity monitoring and U-value measurements of one archetypal building for hygrothermal performance characterisation.

TA-3 [METU, KOR-DER and STBA]: Resident surveys at case study locations with groups from different ages/genders via open-ended interviews to elicit an understanding of residents' experience of living in their homes, usage patterns, and running costs, through different seasons.

TA-4 [METU, KOR-DER, UCL and SAYKA]: A small scale local informal meeting organised at each case study town with local practitioners and relevant private sector organisations to gain insight about the local practice and sector's needs/problems.

WS-B: Identification of Energy Performance Baseline and Performance Gap [UCL]

TB-1 [UCL and METU]: Analysis of data collected at WS-A to develop the building typologies, and identify common damage mechanisms, recurrent issues raised by the residents, critical spaces/seasons, ways in which moisture risk manifests, and common resident behaviour patterns.

TB-2 [UCL, METU]: Analysis of the past weather data from the case study locations to identify varying patterns in the precipitation, temperature, and humidity, and to elicit future exposure.

TB-3 [UCL, UKCMB, METU]: Pre-retrofit Building Performance Simulation (BPS) modelling for each typology to simulate current energy performance under current and future exposure (TB-2) and with realistic use scenarios (TA-3), and setup of an open-access models library. Identification of the impact of user behaviour on building energy performance.

TB-4 [UCL, UKCMB, METU]: Model verification based on the monitored and resident-reported building performance, and quantification of the performance gap based on national and global targets.

WS-C: Developing Solutions [UCL]

TC-1 [UKCMB, METU, KOR-DER, STBA, SAYKA, UCL]: Comparative improvement option evaluation and development of packages of retrofit measures for each dwelling type, targeting problems identified in WS-A and WS-B, and ensuring that proposed measures will improve energy performance to target levels, enhance resident experience and not compromise the heritage value. A relation matrix will be used to identify/evaluate the best trade-offs between these critical factors. The development of improvement packages will be in parallel with/informed by TD-1 activities. Retrofit measures will be selected according to:

1) Global environment, i.e. climate change vulnerability, whole-life energy use and greenhouse gas emissions.

2) Building fabric, i.e. conservation and hygrothermal behaviour; 3) indoor environment quality i.e. user behaviour and agents of deterioration; 4) economics (TC-2).

TC-2 [UCL, METU, UKCMB]: Detailed improvement option evaluation of the retrofit measures identified at TC-1, considering capital costs, operational energy costs, and maintenance costs using simple payback, carbon cost effectiveness and net present value to assess their cost-effectiveness and if should be used at the modelling stage (TC-3).

TC-3 [UCL, METU, UKCMB]: Integration of cost-effective packages of retrofit measures identified at TC-2 into the BPS models developed at TB-2 to estimate the associated energy performance improvement and reduction in greenhouse gas emissions under a range of future climate scenarios.

WS-D: Stakeholder Engagement, Dissemination and Impact [METU]

TD-1 [METU and UCL]: Capacity building and consultation workshops engaging academics, practitioners, heritage conservation bodies, NGO's and policymakers:

• 1st Workshop on Traditional Dwellings under Climatic Risk – focussing on traditional housing under climatic impact, best practice in field survey, community engagement

• 2nd Workshop on Energy Performance Modelling – focussing on challenges/opportunities in energy performance modelling with specific emphasis on traditional dwellings

• 3rd Workshop on Retrofit Solutions – focussing on technical guidance in two countries, their strengths/limitations, their applicability on traditional housing, and how to establish best practice in Turkey

• 4th Workshop on Energy Efficiency and Conservation Through the Lenses of Practice and Policy – focussing on legal/policy framework behind retrofit, energy efficiency and climate resilience

TD-2 [KOR-DER, STBA, UCL, SAYKA]: Knowledge collation via surveys among KOR-DER and STBA's wide networks of academics and practitioners to understand the perceptions of climate induced risks and their management, energy efficiency and related guidance in their respective countries.

TD-3 [METU with all partners]: A final dissemination conference in Ankara, with sessions targeting different stakeholders to present findings, and discuss cultural/financial/legal constraints governing the applicability of developed retrofit solutions.

TD-4 [all partners]: Development of concept notes for UK-Turkey joint research project proposals focussing on various research questions identified, developed or detailed as part of this project.

TD-5 [METU and UCL with all partners]: Writing up the methodological framework paper, with open research questions and an appraisal of how transferable our findings are to the rest of Turkey.
