The problem of clothes drying in new homes in the UK

The current focus on air tight construction to minimise energy use in homes in the UK requires analysis of the behaviour of the occupants. The aim of this paper is to review current literature and explore the methods used to dry clothes, to assess current standards and reccomendation for the drying of laundry in new homes and the issues arising with increased moisture within the building envelope where there may be inadequate ventilation caused by impermeable design Design/methodology/approach: Literature is reviewed on new housing in the UK and as part of a wider study of behaviour questionnairres were delivered to occupants of a recently completed housing estate in the uk to ask the questions with regard to their laundry practice. Findings: There are inherent problems in drying laundry in new air tight homes. This case study identifies 95% of residents on a new estate own a tumble dryer and use either this high energy method for clothes drying or hang clothes internally within the property leading to higher energy use or potential mould growth. Research limitations/implications: Further research is required into how drying laundry impacts on internal air qaulity in new homes designed to be energy efficient Practical implications: The design of new houses needs to be considered to provide a shift in people's behaviour with regard to low energy clothes drying Social implications: Originality/value: Other research has focussed on tenants in social housing in properties of mixed ages. This is the first study which focusses specifically on new energy efficient housing for owner occupiers

Test problems for metamodeling comparison: 5 building performance metrics and 8 theoretical problems

Each dataset consists of 10.000 set of input and output values. Five dataset has been constructed using building performance simulations. Four of these relate to a generic, single-zoned office which have been modelled with the building simulation software BSim (developed by the Danish Building Research Institute). One dataset describes the variability of an educational institution during an early design stage. For this set, we have used the normative software Be15, which is based on ISO 13790. Be15 has also been developed by the Danish Building Research Institute. Eight dataset are based on theoretical problems for which 10.000 calculations have been made with Matlab

Thermal comfort standards, measured internal temperatures and thermal resilience to climate change of free-running buildings: A case-study of hospital wards

In view of the warming climate, there is increasing concern about the likelihood of overheating inside UK buildings that are not mechanically cooled. A number of studies are examining this matter, of which the DeDeRHECC project is one. The recent availability of the UKCP09 future climate data projections has acted as a stimulus to such work. This paper illustrates how field measurement, thermal modelling and the generation of current and future typical and extreme weather years, can be used to provide a picture of the resilience of buildings to climate change. The unified framework for assessing both measurements and current and future predictions that is offered by the BSEN15251 thermal comfort standard is a crucial component. The paper focuses on internal temperatures during the day and at night in wards within the tower building at Addenbrooke’s hospital, which has a hybrid ventilation strategy. The maintenance of thermal comfort in such spaces is critically important and installing air-conditioning in response to climate change is expensive and potentially energy intensive. Fans appear to be a simple retrofit measure that may substantially improve the wards’ resilience to climate change even in extreme years. Whilst healthcare provides the back cloth, the methodology developed has a much wider utility for assessing thermal comfort in buildings in the current and future climate of the UK
