analysis of uk Domestic Building retrofit scenarios based on the e on retrofit research house using energetic hygrothermics simulation energy efficiency indoor air quality occupant comfort and mould growth potential
Building and Environment, 2013Co-Authors: Matthew R. Hall, Sean P. Casey, Dennis L. Loveday, Mark GillottAbstract:The work forms part of the CALEBRE project (2008–2013), the aim of which was to investigate a suite of technologies and staged approaches for retrofit upgrades for ‘hard-to-treat’ solid/thin cavity masonry-walled UK Domestic Buildings that would i) reduce operational energy demand/carbon emissions, and ii) be acceptable and appealing to the Building occupants. The E.ON Retrofit Research House (Nottingham, UK) was used as an instrumented test platform as part of this study. The retrofitting phases (and technologies) have been used as the basis for the modelling methodology in this paper, together with the corresponding envelope assemblies, material properties, climate, and internal load parameters. The approach to retrofit was to increase air tightness (reduce ACH), decrease static U-values of the external envelope (wall, floor and glazing), and upgrade heating system efficiency. This was complemented by a combination of options that included a whole-Building system of mechanical ventilation with heat recovery (MVHR). These interventions were analysed alongside simulated passive buffering of variations in indoor air psychrometric conditions using conventional (clay, timber) and advanced (mesoporous silica) wall surface treatments. Each retrofit scenario was modelled using an energetic hygrothermics Building performance simulation (BPS) approach to determine the combined effects of retrofit packages on indoor air psychrometric conditions, external envelope (dynamic) heat transfer, operational energy efficiency, occupant comfort, and mould growth potential. It is proposed that this approach can provide the basis for an intelligent risk management strategy to inform both the design and deployment of retrofit upgrade packages intended for residential Buildings.

Will global warming reduce the carbon emissions of the Yorkshire Humber Region's Domestic Building stock—A scoping study
Energy and Buildings, 2008Co-Authors: Ian C. WardAbstract:There is evidence from the International Panel of Climate Change that the UK will experience a mean rise in ambient air temperature over the coming years. Such a rise in temperature will change the requirements for heating and cooling of Domestic Buildings. This scoping paper explores this issue with respect to the housing sector in the Yorkshire Humber Region of the UK and comes to the conclusion that the regions Domestic sector poses major problems with respect to the stated carbon savings required by the UK Government.

Building INTEGRATED VEGETATION AS AN ENERGY CONSERVATION MEASURE APPLIED TO NON-Domestic Building TYPOLOGY IN THE UK.
2011Co-Authors: Apeksha Gupta, Matthew R. Hall, Christina J. Hopfe, Yacine RezguiAbstract:Amongst a large range of passive energy conservation measures (ECMs), Building integrated vegetation (BIV systems) is witnessing a rapid growth in both research and market development (Bass and Baskaran, 2003). Unfortunately, their uptake remains limited in the UK, although the existing non-Domestic Building stock is in urgent need of energy conservation in order to meet the UK’s carbon reduction target. This research aims at analysing the performance of BIV systems as an ECM specifically to the nonDomestic Building typology. For a six-storey office Building in London, a sensitivity analysis is conducted using different parameters to assess the performance of BIV systems. The optimised solution of these parameters that achieve maximum energy savings was applied to the Building typology. The outcomes of this paper can be used as a design tool for BIV systems in order to maximise energy savings of a Building.

a probabilistic energy model for non Domestic Building sectors applied to analysis of school Buildings in greater london
Energy and Buildings, 2012Co-Authors: Wei Tian, Ruchi ChoudharyAbstract:Abstract The diversity of non-Domestic Buildings at urban scale poses a number of difficulties to develop models for large scale analysis of the stock. This research proposes a probabilistic, engineering-based, bottom-up model to address these issues. In a recent study we classified London's non-Domestic Buildings based on the service they provide, such as offices, retail premise, and schools, and proposed the creation of one probabilistic representational model per Building type. This paper investigates techniques for the development of such models. The representational model is a statistical surrogate of a dynamic energy simulation (ES) model. We first identify the main parameters affecting energy consumption in a particular Building sector/type by using sampling-based global sensitivity analysis methods, and then generate statistical surrogate models of the dynamic ES model within the dominant model parameters. Given a sample of actual energy consumption for that sector, we use the surrogate model to infer the distribution of model parameters by inverse analysis. The inferred distributions of input parameters are able to quantify the relative benefits of alternative energy saving measures on an entire Building sector with requisite quantification of uncertainties. Secondary school Buildings are used for illustrating the application of this probabilistic method.

Energy analysis of the non-Domestic Building stock of Greater London
Building and Environment, 2012Co-Authors: Ruchi ChoudharyAbstract:Abstract This paper presents a Bayesian approach for developing city-scale energy models of the built environment and demonstrates its application to non-Domestic Buildings in Greater London. The work draws upon available information of the Building stock, such as: mapping databases, floorspace statistics, energy benchmarks, and measured energy consumption reported in display energy certificates of public Buildings. The resulting model is able to describe the spread due to variation of energy consumption across Buildings within a similar category. These spreads (or distributions) can be used for estimating the probability distribution of the gross energy consumption per local authority in Greater London. The work is driven by the need to quantify future energy demand of Buildings in their urban context as a function of projected growth of Buildings and populations, refurbishments, policies incentivizing energy efficiency measures, and changes in Building operation. The focus on the non-Domestic sector enables a framework that accommodates diverse set of activities and uses of Buildings within an urban region.
