HERITAGE RETROFITS | MYANMAR Brickwork of internal walls are left exposed to allow restored buildings to breathe skin, concrete-block infill walls and single glazed. In this context, it was relatively simple to model the three typologies to demonstrate the positive impact that simple alterations can make. One key finding from the research was the impact that the monsoon season has on building performance. In line with theory, the small diurnal temperature range the variance between daytime temperature and night-time temperature in the summer (monsoon season) showed that thermal mass had the least effect on performance during this season. No lag time was seen for the adapted building in July and the total energy use was still lower than the unadapted building, both of which are thermally massive. This proved that the additional interventions of insulation and double glazing were the key elements affecting the reduced energy consumption. The quality of the environments we inhabit are essential for our health, mental health and wellbeing. We now feel this more acutely thanks to the lockdowns Doh Eain wants to cleanup Yangons trash alleys and bring community life back to the streets and stay-at-home orders we have experienced over the past 18 months. Making small interventions to improve these environments is important, and not just for the money they can save on energy bills. Combining this with a broader social impact is important at Doh Eain. Our work offers a wider reach to communities and neighbourhoods by supporting the renewal of public spaces through our participatory design approach and community engagement focus. Access to public space is another core element of improved wellbeing that has been proven during the global pandemic and seen around the world. Millions of people do not have access to private outside space, so public spaces become essential for socialising, having a place to rest, exercise, and play. Yangon fares poorly in its provision, with just 0.32m2 of public space per person. Jakarta has 6m2, Bangkok 8.5m2 and Paris 30m2. Covid-19 and the military coup have driven us to review what we can and should be doing. Our core areas of focus within Doh Eain protecting heritage, improving buildings, supporting communities and improving access to public space are now all the more important in the new normal. MODELLING OF INTERVENTIONS The modelling of unadapted, adapted and new buildings was carried out using E20 Hourly Analysis Software by Carrier, also known as HAP51. The modelling showed the impact the building fabric has on the demand for energy consumption from cooling load to maintain a steady internal temperature at 24C (with a 1K buffer). Data inputted was: material data, occupancy, weather data, air-change rates and electrical loads. which represented the peak days for the months of April, July and December. For July (monsoon) the energy load range is very low for adapted. This difference to unadapted suggests that it is not the similarities in construction such as thermal mass, which is affecting this difference, but is a result of the additional interventions of insulation and double-glazing. 28 October 2021 www.cibsejournal.com CIBSE Oct21 pp26-29 Myanmar retrofit.indd 28 24/09/2021 14:18
