According to an expert from Cambuild, buildings that are performing well now, and those currently being designed and built for the today’s climatic conditions, may become intolerable for occupants by 2068 (50 years time) unless we factor in concepts such as active cooling and associated high-energy usage. There is compelling scientific evidence that our climate is changing, and it is probable that average temperatures will increase by several degrees over the coming century.
According to roofing repairs, these increases in temperature are expected to have a major impact on the indoor environment of buildings, because of this is recommended to get advise from experienced roofers to build a green roof. It is essential that buildings being designed and built today are future-proofed so they can adapt to changes in external temperatures and humidity, light levels, energy usage and so on, visit this link if you want to read more about professional roofing services.
To be fair, the construction industry has already made significant steps towards tackling climate change through limiting the amount of carbon emitted – both in the materials used (embodied energy) and predicted energy usage – by using simulation programmes such as IES, along with BREEAM and LEED.
The energy message emphasis on heat-saving in winter using highly-insulated and airtight buildings also means there is a danger of overheating in the summer months. This presents a different challenge. CIBSE has produced quite a number of guidance documents in this respect, such as TM52 (The limits of thermal comfort: avoiding overheating in European buildings: Developed for “free-running” commercial buildings) and TM59 (Design methodology for the assessment of overheating risk in homes).
The health and wellbeing impacts of overheating (see Mona Holtkoetter’s article in October 2017 edition of Building Services News) can be significant for residents, resulting in stress, anxiety, sleep deprivation and even early deaths in heatwaves, especially in cases of vulnerable occupants.
Among the concepts now being embraced to combat these issues are highly-insulated pipework, the use of Thermoplastic Pipe Hangers which is highly important to have on a building since it can help minimize movement between pipe and structure, other concepts include; insulated heat interface units; ventilated utility cupboards; LED lighting; and installing mechanical ventilation heat recovery units, with summer bypass and boost mode, to increase the ventilation rate when required.
