Integration Of Renewables

With the growing concern about decreasing CO 2 emissions, renewable energy sources are being vastly integrated in the energy systems worldwide. This will bring new challenges to the network operators, which will need to find sources of flexibility to cope with the variable-output nature of these technologies. Demand response and multi-energy systems are being widely studied and considered as a promising solution to mitigate possible problems that may occur in the energy systems due to the large-scale integration of renewables. In this work, an optimal model to manage the resources and loads within residential and commercial buildings was developed, considering consumers preferences, electrical network restrictions and CO 2 emissions. The flexibility that these buildings can provide was analyzed and quantified. Additionally, it was shown how this model can be used to solve technical problems in electrical networks, comparing the performance of two scenarios of flexibility provision: flexibility obtained only from electrical loads vs. flexibility obtained from multi-energy loads. It was proved that multi-energy systems bring more options of flexibility, as they can rely on non-electrical resources to supply the same energy needs and thus relieve the electrical network. It was also found that commercial buildings can offer more flexibility during the day, while residential buildings can offer more during the morning and evening. Nonetheless, Multi-Energy System (MES) buildings end up having higher CO 2 emissions due to a higher consumption of natural gas.

To save energy and commit to the environmental protection and sustainable development of green ecological buildings, how to integrate solar energy systems with the reconstruction of multi-storey residential buildings has become a key area of growth in the current construction market. Fully integrating solar thermal energy systems with such reconstruction is a major problem. In this paper, the integration of solar thermal energy systems, roof design, and elevation design were studied systematically. Various effective schemes were presented, laying a foundation for the integrated design of existing multi-storey buildings and solar thermal energy systems during reconstruction.

The building stock accounts for a significant portion of worldwide energy consumption and greenhouse gas emissions. While the majority of the existing building stock has poor energy performance, deep renovation efforts are stymied by a wide range of human, technological, organisational and external environment factors across the value chain. A key challenge is integrating appropriate human resources, materials, fabrication, information and automation systems and knowledge management in a proper manner to achieve the required outcomes and meet the relevant regulatory standards, while satisfying a wide range of stakeholders with differing, often conflicting, motivations. RINNO is a Horizon 2020 project that aims to deliver a set of processes that, when working together, provide a system, repository, marketplace and enabling workflow process for managing deep renovation projects from inception to implementation. This paper presents a roadmap for an open renovation platform for managing and delivering deep renovation projects for residential buildings based on seven design principles. We illustrate a preliminary stepwise framework for applying the platform across the full-lifecycle of a deep renovation project. Based on this work, RINNO will develop a new open renovation software platform that will be implemented and evaluated at four pilot sites with varying construction, regulatory, market and climate contexts.

Hot And Humid Climate

The use of Prismatic Skylights and its effects as a passive Energy Conservation Strategy in “Residential” and “Big Box Commercial Buildings” in hot and humid climate has been evaluated throughout this project. The potential benefits of using skylights reside in the fact that it reduces electrical lighting necessities but at the same time it contributes to an upsurge of the Cooling Loads of the conditioned space. Acknowledging the impact of skylights is fundamental to elaborate an optimized design of a building’s energy efficient mechanical system. To reach a sound conclusion, the evaluated buildings were modeled and their performance was simulated using the Department of Energy Simulation Program “Energy Plus”. To be able to compare the Energy Conservation Measure case (Using Skylights) with the Base Line (No Skylights), a photometric sensor was modeled to ensure that both cases sourced the same amount of light visible in the electromagnetic spectrum. Considering the Heating, Cooling and lighting energy consumption as variables, the variance between the ECM and the Base line for the residential case was 5% more energy consumption with skylights. For the Big Box Commercial Building there was a 5% deduction in energy consumption in the ECM case using 5% roof area covered with skylights. The results obtained from this investigation reveal a very promising effect in the implementation of skylights in “Big Box Commercial Buildings”, but not so optimistic in the case of “Residential Buildings” for hot and humid climate as shown by the simulation and monitoring data from the experimental case.

Poor power supply is a major bottleneck to the technological development of the country and this has forced building occupants to shift to dependence on generating sets of different types and brand which subject its users to myriad of effects. This study was aimed at assessing perception of the users of generators in buildings on the effects associated with its usage in Ibadan Metropolis, Nigeria. The study area was divided into core, transition and suburban residential zones. Multistage and quota sampling techniques were used to select respondents sampled in residential and commercial buildings respectively. Descriptive and inferential statistical techniques were used to analyse data collected. The study showed that 50.29%, 51.19%, 45.90% of residential buildings’ respondents in the core, transition and suburban zone while 56.41%, 43.33% and 42.86% of occupants of commercial buildings in the corresponding core, transition and suburban zone indicated that hearing problem was the most physiological effect that the use of generating sets exposed them to. Cut injuries from the elcetro-mechanical components of generating sets were the most prominent injuries had by the occupants of residential buildings while irritation of the eyes during refueling was the most significant effect had by respondents in the commercial buildings. High cost of fuel and damage to electrical appliances were the most uncomfortable indicator with uncomfortability index of 0.804 and 0.776 in residential and commercial buildings respectively. The study also found that the use of generating sets had caused structional, functional and aesthetical effects on the building elements. It was recommended that there is dire need on the part of government to enhance environmental sustainability by provision of sustainable energy sources to buildings in view of the effects associated with the use of generating sets.

PurposeThe demand for potable water increases with population growth, given its role in sustaining life. As part of a wider approach to ensuring sustainable provision, this has prompted a number of carefully formulated water efficiency improvement plans for buildings, one of the highest water-consuming sectors. This paper presents a detailed analysis of water efficiency potential for a multi-storey commercial complex and an office building in central Malaysia.Design/methodology/approachIn this study, a detailed analysis of the water use and efficiency of the water fittings was carried out. Important data such as historical water use and details of water fittings were acquired during a field survey. A series of water flow rate tests were conducted at the selected buildings and each of the water systems was analysed separately, using the criteria of water efficiency stipulated by a locally applied green building tool. A comparison of water consumption before and after the improvement plan was then made.FindingsFindings from the field surveys indicate that only some of the water fittings were certified with recognised efficiency ratings, which suggests a good opportunity for improvement. The proposed replacement of more-efficient fittings could potentially improve the obtainable green credit points by at least 10 from a maximum of 15. A cost–benefit analysis for a water fitting replacement scheme shows that the estimated payback period is less lengthy for the larger commercial building due to the higher potential savings.Practical implicationsStrategies for improvements in water efficiency for existing non-residential buildings are provided in this paper. The same water consumption analysis procedure can be used by maintenance engineers and other practitioners in building assessments where water efficiency and sustainability in building operation are of concern.Originality/valueThis case study responds to the need for efficient use of freshwater and provides insight into the water efficiency opportunities for commercial buildings. The potential cost savings for replacements of inefficient water fittings have been analysed using a green building tool as a guide. This has not been extensively analysed in previous studies.
