Building regulations are an important policy instrument available to governments wishing to improve building energyefficiency, which should be a priority to policy-makers wishing to target cost-effective avenues in support of carbonabatementtargets. Meanwhile, building system commissioning has been recognized as a cost-effective measure to cutenergy consumption, but in practice commissioning quality can deliver less-than-satisfactory outcomes. Regulationneeds to better support commissioning outcomes. A five-grade commissioning scale is developed to assess the qualityof commissioning and propose a common language to assist with regulation setting. Using this scale, buildingregulation and polices related to new and refurbished building commissioning were analysed in comparative casestudies between jurisdictions England and California. This study finds that Californian regulations mandate a higherquality of commissioning and regulations that are more enforceable. The crucial elements to support bettercommissionedbuildings were identified as: outputs-focused regulation (not input based); regulation and processclarity; commissioning agents and building official training; as well as acknowledging the financial burden ofupholding more complex building regulations. For the full benefit of commissioning to be realized, policy andregulations for existing buildings will be required.

Extending the narrow scope of building management systems to form the 'intelligent building' has led to the widespread use of proprietary 'enterprise' software platforms and networks in both monitoring and control. The PC user is only too familiar with the vulnerability of networked computers to malicious software. But it is only recently that attention has been paid to the possibility of virus damage to process controllers. The hazard for 'building management systems' functionality is real but the risk is difficult to assess. Pressures on system procurement and upgrades aimed at improving functionality bring with them increased exposure to the probability of a successful attack. Most published security protocols may engender a false sense of security. The key defence is to ensure a 'fall-back', 'black start', 'dumb capability' within the intelligent building. © 2012 Copyright Taylor and Francis Group, LLC.

Jennings M, Shah N, Fisk D, 2012, Optimising the arrangement of finance towards large scale refurbishment of housing stock using mathematical programming and optimisation, Proceedings of the 25th International Conference on Efficiency, Cost, Optimization and Simulation of Energy Conversion Systems and Processes, ECOS 2012, Vol: 7, Pages: 213-228

The U.K. will require significant refurbishment interventions to the existing building stock if her 2050 greenhouse gas emissions targets are to be met. In parallel, the current economic recession is forcing some investors and creditors to look to new strategies of achieving healthy returns on property assets. The research presented in this paper seeks to analyse these problems using optimisation. A mixed integer linear programming model is presented for arranging the finance for large scale refurbishment schemes. The objective function minimises the costs of arranging finance. This model feeds into a technology urban resource network model, which allows for optimised statements of the refurbishment actions to be performed, their timing, and their quantity. An example of an urban area seeking to reduce its housing heating emissions is presented. Results suggest that division of finance, technology capacity, and organisational capacity by tenure is more appropriate than simpler representations. Overall, the optimisation models presented are thought to offer a robust method going forward for the arrangement of finance towards energy efficient refurbishment of housing stock at the large scale.

In recent years there has been an escalation in academic interest in making cities more sustainable, particularly through the refurbishment of buildings and heating networks. To answer the question of what is the optimal order in which neighbourhood scale interventions should be made, this study has been carried out to determine the optimized plan for low carbon investments in existing assets. First, a model has been constructed in the form of traditional mixed integer linear programming (MILP) using the resource-technology network (RTN) framework. This model is a multi-period spatially and temporally explicit case study over a period of twenty years of four neighbourhoods comprising more than 1,300 people. The main equations which have been extended include a resource balance and technology asset balance for the group of terraced houses in the neighbourhood. The neighbourhood is divided up into four nodes of interest. Each node has associated parameters for daily/seasonal heat and electricity demand and also 'year 1' initialised incumbent technologies. Annual investment decisions have been determined by both minimum and maximum annual budgetary constraints. The decision variables can be investments in more efficient technologies or improvements in thermal envelopes of buildings. The application of MILP optimizers to the refurbishment strategy of a neighbourhood scheme, as presented in this study, is a novel approach, as typically heuristics are used for refurbishment models on a similar scale. Specifically, MILP allows a number of exclusivity and inclusive decision functions to be formulated, such as the dependence of district heating networks on the investment in a discrete community scale CHP plant. Results from this model suggest that it is better for scheme managers to invest in demand side interventions before replacing current technologies when minimizing emissions towards a exogenous emissions trajectory. This study also indicates that there is value-added b

Cities account for approximately two-thirds of global primary energy consumption and have large heat and power demands. Combined heat and power (CHP) systems offer significant efficiency gains and emissions reductions, but they can have high upfront investment costs and create nuisance pollution within the urban environment. Urban planners therefore need to understand the tradeoffs between limitations on CHP plant-size and the performance of the energy system. This paper uses a mixed-integer linear programming model to evaluate energy system designs under a range of scenarios. The results suggest that cost penalties of up to 10% and energy-efficiency penalties of up to 60% may be implied by restrictions on maximum CHP plant size.

Weber C, Keirstead J, Samsatli N, Shah N, Fisk Det al., 2010, Trade-offs between layout of cities and design of district energy systems, Proceedings of the 23rd International Conference on Efficiency, Cost, Optimization, Simulation, and Environmental Impact of Energy Systems, ECOS 2010, Vol: 3, Pages: 175-182

The reduction of CO2 emissions linked with transport and energy services (heating, domestic hot water, cooling and electricity), together with the increased use of renewable energies, remains a high priority on various political agendas. In this paper, the trade-offs between the optimal layout of a city in terms of transport and the resulting district energy system are analysed. The starting point of the study is a greenfield site in England, on which a small eco-town, with a pre-defined number of inhabitants, shall be built. Conventional assumptions are made about the number and types of buildings according to the number of inhabitants. A layout model is then used to define the optimal layout of the city to reduce transport requirements. Finally, the optimal mix of technologies that will satisfy the energy services, taking into account spatial and other constraints, is computed using advanced process optimization techniques. The results show how increasing the density of cities to reduce transport energy requirements influences the opportunities offered by certain renewable energy technologies for heat and power services.
