“…In the case of residential buildings, different load curve models were evaluated and analyzed to provide energy models that consider end uses, habits, and behaviors [7]. Energy estimation with better accuracy can also determine the suitable demand side response from the available information with tolerance to estimation error [8]. This estimation methodology to assess the energy consumption in a building has significant benefits in terms of energy efficiency evaluation and potential energy savings [9].…”

Electrical energy usage in buildings is a challenging issue because many old buildings were not originally built to achieve energy efficiency. Thus, retrofitting old buildings to net-zero buildings can benefit both the owner and electric utilities. In this study, the BEC (building energy code) software was used to evaluate energy aspects of retrofitted buildings in compliance with Thailand’s building energy code to achieve a net-zero energy building. In addition, economic aspects were also studied to verify the feasibility for a project’s owner to invest in a retrofitted existing building. An existing residential building in Thailand was used as a case study. The results in terms of energy after retrofitting existing buildings into net-zero energy buildings show that the total energy consumption can be reduced by 49.36%. From an economic perspective, the investment cost for a retrofitted building can be compensated by energy saving in terms of discounted payback period (DPP) for approximately 4.36 years and has an IRR (internal rate of return) value of 19.23%. This result evidences the potential in both energy and economy for a project’s owner to invest in a retrofitted existing building in compliance with the building code, with potential for implementation with benefits on both electrical utilities and the project’s owner.

“…These costs can vary considerably between organisations [109,119] and can be very high [76,81,89]. In addition to the capital costs, there are also hidden production costs such as time spent finding suitable equipment for participating in DSR, which have been highlighted as one of the main barriers to participation [121]. Equipment may be unsuitable because it cannot meet DSR performance requirements, such as responding to a DSR signal within a specified timeframe or because it is unable to interact with the businesses' existing equipment.…”

The decarbonisation of electricity systems and the associated increase in variable generation sources requires an increase in power system flexibility. Demand side response (DSR) is widely viewed as a cost-effective source of flexibility, with considerable market potential. To date, the main DSR providers have been energy intensive firms. However, the expectation is that non-energy intensive consumers such as commercial firms and public sector organisations, will also help to provide system flexibility. Despite its DSR potential, the commercial and public sector has received little attention in the literature. This paper helps address this gap by identifying and exploring barriers to the participation of large commercial firms and public sector organisations in DSR through a review of the academic and grey literature on DSR. Drawing on the literature on barriers to energy efficiency, we use concepts from orthodox and behavioural economics, organisational studies and social practice theory to frame our analysis. The article argues that barriers to participation in DSR exist at the level of the organisation and not only the site. For large commercial firms and public sector organisations, the combination of having small individual electricity loads and complex internal decision-making processes can hinder their uptake of DSR. The hidden costs of participation, issues of bounded rationality and what the energy is used for within different organisations also limit the firms' ability to participate in DSR. literature is the 'energy-efficiency gap', which examines the reasons for organisations' underinvestment in apparently profitable EE initiatives [22][23][24].The literature on the EE gap can be useful to examine barriers to DSR participation for three reasons. First, studies on the EE gap tend to use a multi-disciplinary approach in their analysis, which can enable the identification of a more comprehensive set of barriers as the problems under examination are considered from different perspectives. For example, while some theories will focus on the barriers that originate at the level of the individual others will emphasise the role of organisational factors in restricting the uptake of EE projects. Second, from the perspective of firms and public sector organisations, there are several similarities between EE and DSR. Both DSR and EE are energy management innovations [21]. Both are relatively optional. The benefits of increased energy efficiency and more demand side flexibility in the system are generally agreed, and both measures are often advocated as being cost-effective for businesses. However, a gap remains between estimates of EE and DSR potentials and businesses' uptake of these initiatives. Within firms, both DSR and EE are the responsibility of energy departments but require support from other parties of the organisation and are both likely to be evaluated by the same criteria [15,21,25]. Third, the EE literature includes barriers that focus on the features of the organisation [26,27] rather than solely o...

“…This bottom-up approach allows the estimation of potentials on the resolution of appliances and sectors and is different from methods estimating the DR potential based on load profiles, electricity usage records or building energy modelling (cp. Curtis et al [30]). The practical potential additionally requires data on the willingness to use the appliances for DR purposes.…”
