Purpose Contrary to the traditional technology project perspective, real estate investors see building-specific renewable energy (on-site energy) investments as part of the property and as something affecting the property’s ability to produce a (net) cash flow. This paper aims to show the value-influencing mechanism of on-site energy production from a professional property investors’ perspective. Design/methodology/approach The value-influencing mechanism is presented with a case study of a prime logistics property located in the Helsinki metropolitan area, Finland. The case study results are compared with the results of a survey answered by over 70 property valuation professionals in the Finnish real estate market. Findings Current valuation practice supports the presented value-creation mechanism based on the capitalisation of the savings generated by a building’s own energy production. Valuation professionals see benefits beyond decreased operating expenses such as enhanced image and better saleability. However, valuers acted more conservatively than expected when transferring these additional benefits to the cash flows of the case property. Practical implications Because the savings in operating expenses can be capitalised into the property value, property investors should consider on-site energy production when the return of on-site energy exceeds the return of the property. This enhances the profitability of on-site energy, especially in urban areas with low initial yields. Originality/value This is the first research paper to open the value-influencing mechanism of on-site energy production from a professional property investors’ perspective in commercial properties and to confirm it from a market study.

Overheating in residential building is a challenging problem that causes thermal discomfort, productivity reduction, and health problems. This paper aims to assess the climate change impact on thermal comfort in a Belgian reference case. The case study represents a nearly zero energy building that operates without active cooling during summer. The study quantifies the impact of climate change on overheating risks using three representative concentration pathway (RCP) trajectories for greenhouse gas concentration adopted by the Intergovernmental Panel on Climate Change (IPCC). Building performance analysis is carried out using a multizone dynamic simulation program EnergyPlus. The results show that bioclimatic and thermal adaptation strategies, including adaptive thermal comfort models, cannot suppress the effect of global warming. By 2050, zero energy buildings will be vulnerable to overheating.

<p>Over the last decade, construction of hydropower dams has increased rapidly around the world, including in developing countries. For many countries including Laos, energy production and export play a significant role in promoting and boosting economic growth and development. Energy production generates substantial revenue and foreign exchange from exporting electricity and expands economic activity domestically. However, construction of hydropower dams also causes negative effects on the people who live at and around the dam site. Some local communities have been affected indirectly, while others require relocation to other areas bringing significant change, including for women. This research explores the impact of resettlement from hydropower dam creation on women by using the Nam Mang 3 hydropower dam in central Laos as a case study. This dam, completed in 2005, required the relocation of approximately 150 households from two villages at the dam site. The research draws on a social constructivist epistemology, qualitative methods including semi-structured interviews, and analysis of relevant policy documents. Interviews involved 18 participants including both male and female from the three affected villages. Results indicate that the resettlement of villagers by the Nam Mang 3 hydropower dam has generally improved living conditions of the resettled communities. Women were found to have greater opportunities to benefit from home-based business, employment and wage labouring. In addition, with better access to modern facilities and services, women have been able to save greater time from agricultural activities and divert this time saving to other economic activities. Overall, access to water supplies, roads, and transport have reduced women’s workload significantly. Access to improved health services and facilities have also improved women’s wellbeing. Girls have greater opportunities to attend school and seek employment in towns. However, this research identified some challenges experienced by the resettled such as the reduction of agricultural and grazing land area, and that new livelihood options were not accessible to all women. Instead of these challenges, the experience with the Nam Mang 3 hydropower project has highlighted one of the key lessons learnt that is worth highlighting for future resettlement programs, which is to have the resettlers fully engaged in the entire process of resettlement and livelihood strategy development.</p>

Purpose This study aims to provide an example of how higher education institutions (HEIs) can use a successful campus infrastructure project to fund a student- and faculty-led, community-success platform that advances the sustainable development goals (SDGs). Design/methodology/approach The authors applied conceptual models for systems thinking and creating virtuous cycles to analyze Millersville University’s work to establish a community-impact, micro-grant fund using cost savings and utility rebates associated with a new campus zero-energy building. The analysis provides a case study that other HEIs can implement to create university and community virtuous cycles that advance the SDGs. Findings The case study suggests that as HEIs face increasing financial challenges, opportunities exist to capitalize on philanthropic giving and other funding sources to support community prosperity and increase university vitality through a shared responsibility paradigm centered on the SDGs. Practical implications This case study identifies specific funding sources that HEIs can use to fund campus and community sustainability projects using the SDG framework, mechanisms for establishing shared purpose around that impact and a conceptual model for thinking about opportunities to leverage philanthropic giving to create a virtuous cycle that increases university vitality through community impact. Social implications Constructing a campus zero energy building funded in part through philanthropic giving provided a unique opportunity to explore how a project’s success can be leveraged to create additional community successes. This case study offers an example for how to convert one success into a platform that funds projects that have direct community impact in one or more of the SDG goal areas. Originality/value This paper aims at bridging the gap between theoretical frameworks for community sustainable development and descriptive-only case studies by using a case study to demonstrate a conceptual model or framework for advancing community sustainability (Karatzoglou, 2013). The case study provides a unique model for using utility rebates associated with an infrastructure project that was funded through philanthropic giving to establish a fund for projects that support the community. Utility rebates associated with campus energy efficiency projects are often otherwise overlooked, used to fund additional energy efficiency projects or simply returned to a university’s operating budget. For some HEIs, this model may connect the work of facilities staff to student success in ways that have not previously been explored. For others, this alternative use of utility rebates may offer an opportunity to increase the investment value of utility rebate dollars by creating virtuous cycles within their communities that contribute to university vitality.

As a result of the impact of energy consumption, research on ultra-low energy, nearly zero-energy, and zero energy buildings has been conducted in China. However, the design of the nearly zero-energy building is flexible; the traditional architectural design method is not fully applicable to nearly zero-energy buildings. The paper proposed a performance-based design method based on overall energy consumption and progress for the nearly zero-energy building. The design process of the relevant cases was also analyzed. The factors of cold and heat sources, environment, and renewable energy were combined to make a comprehensive analysis to get the optimal scheme of the nearly zero-energy building in the case. In general, the performance-based design method has a certain guiding significance for the design of nearly zero-energy buildings and certainly promotes the expansion of the nearly zero-energy building industry in China.
