In recent years, the number of publications on innovation in the construction industry has increased. Many of these documents address qualitative issues, e.g. policies for innovation and present case studies. A more quantitative approach is taken in this paper, which is the continuation of a previous study. It focuses on main types and sources of innovation in the construction industry, and includes an analysis of 55 years of publications in two leading Dutch professional journals. The results show a recent increase in innovation, with two-thirds of innovations coming out of supplying industries. Construction companies contribute mainly in process innovations. Innovation in construction remains to be technology- rather than market-driven. Regulations have a surprising impact, as over one-third of all counted new innovations are related to new regulations.
Since the film of Al Gore An inconvenient truth, sustainability stands high on the national agenda of most countries. Concern for the environment is one of the main reasons in combination with opportunities to innovate. In general, innovation and entrepreneurship are important in the realm of national economies because they hold the key to the continuity and growth of companies (e.g. Hage, 1999; Cooper, 1987; Van de Ven, 2007) and economic growth within a country. It is therefore obvious that national governments are investing money to enable and improve innovation management and entrepreneurial behaviour within organizations with sustainability in mind. Policy measures are aimed at reduction of carbon dioxide emission, waste management and alternative use of energy sources and materials. In line with these measures companies are urged to integrate sustainability in their business processes and search for innovative sustainable solutions. While on a national level policy measures towards a more sustainable society are defined, enterprises - and especially small and medium sized companies - lag behind and fail in incorporating these measures appropriately in their day-to day business. As a result research for sustainability has become an important driver for innovation. Within the Centre for Innovation and Entrepreneurship (CI&E) at The Hague University of Applied Sciences we have taken the initiative to develop an innovation and research program for the construction industry to help small and medium sized companies (SME's) integrate sustainability in their business processes, while simultaneously professionalizing students and lecturers. This paper is part of ongoing research among 40 companies in the region of South-Holland. The companies are mostly SME's varying from very small (6 employees) to middle-sized (more than 100). According to Rennings (2000) while innovation processes toward sustainable development have received increasing attention during the past years, theoretical and methodological approaches to analyse these processes are poorly developed. This paper describes a theoretical approach developed at our university's Centre for Innovation and Entrepreneurship, which combines education and research. It is an inductive approach that departs from real-life problems encountered by companies, and is aimed at developing a model that supports companies in integrating sustainability in their business and innovation processes. We describe the experiences so far with a number of companies in the construction industry, which participate in the innovation and research program described above and the barriers they encounter. Our sustainable program is centred on four themes: cradle-to-cradle, social corporate responsibility, climateneutral construction and sustainability and customer orientation in the building process. It is an exploratory research in which students and undergraduates are involved under the supervision of a lecturer as senior researcher of this program. Through an in-depth analysis of the companies, participant observation and indepth interviews with the owners/directors of the companies, experts and prominent sustainable trendsetters, insight is gained in innovation processes towards sustainable development. Preliminary conclusions show that on a company level one of the main bottlenecks is the dilemma posed by the need for profit for the continuity of a company, while taking into account people and planet. The main bottleneck is however the inability of companies to translate policy measures into strategy and operations. This paper is set up as follows. In section 2 we give an account of European and Dutch policy measures geared at stimulating sustainability in a business context and especially the building and construction industry. In section 3 an overview is given of the economic importance and characteristics of the Dutch building and construction industry and the problems in this sector. These problems are offset against the opportunity of sustainability as a strategic option for SME's in this sector. In section 4 the innovation and research program developed at the CI&E is introduced in the context of the main research question. Following that in section 5, methodological choices are addressed and the research design is presented. We finalize this paper in section 6 with our conclusions and recommendations for further research.
From the article: Abstract. This exploratory and conceptual article sets out to research what arguments and possibilities for experimentation in construction exists and if experimentation can contribute towards more innovative construction as a whole. Traditional, -western- construction is very conservative and regional, often following a traditional and linear design process, which focuses on front-loaded cost savings and repetitive efficiency, rather than securing market position through innovation. Thus becoming a hindrance for the development of the sector as a whole. Exploring the effects of using the, in other design-sectors commonly and successfully practiced, “four-phased iterative method” in architectural construction could be the start of transforming the conservative construction industry towards a more innovative construction industry. The goal of this research is to find whether the proposed strategy would indeed result in a higher learning curve and more innovation during the - architectural- process. Preliminary research indicates that there is argumentation for a more experimental approach to construction.
Buildings are responsible for approximately 40% of energy consumption and 36% of carbon dioxide (CO2) emissions in the EU, and the largest energy consumer in Europe (https://ec.europa.eu/energy). Recent research shows that more than 2/3 of all CO2 is emitted during the building process whereas less than 1/3 is emitted during use. Cement is the source of about 8% of the world's CO2 emissions and innovation to create a distributive change in building practices is urgently needed, according to Chatham House report (Lehne et al 2018). Therefore new sustainable materials must be developed to replace concrete and fossil based building materials. Lightweight biobased biocomposites are good candidates for claddings and many other non-bearing building structures. Biocarbon, also commonly known as Biochar, is a high-carbon, fine-grained solid that is produced through pyrolysis processes and currently mainly used for energy. Recently biocarbon has also gained attention for its potential value with in industrial applications such as composites (Giorcellia et al, 2018; Piri et.al, 2018). Addition of biocarbon in the biocomposites is likely to increase the UV-resistance and fire resistance of the materials and decrease hydrophilic nature of composites. Using biocarbon in polymer composites is also interesting because of its relatively low specific weight that will result to lighter composite materials. In this Building Light project the SMEs Torrgas and NPSP will collaborate with and Avans/CoE BBE in a feasibility study on the use of biocarbon in a NPSP biocomposite. The physicochemical properties and moisture absorption of the composites with biocarbon filler will be compared to the biocomposite obtained with the currently used calcium carbonate filler. These novel biocarbon-biocomposites are anticipated to have higher stability and lighter weight, hence resulting to a new, exciting building materials that will create new business opportunities for both of the SME partners.
Lightweight, renewable origin, mild processing, and facile recyclability make thermoplastics the circular construction materials of choice. However, in additive manufacturing (AM), known as 3D printing, mass adoption of thermoplastics lags behind. Upon heating into the melt, particles or filaments fuse first in 2D and successively in 3D, realizing unprecedented geometrical freedom. Despite a scientific understanding of fusion, industrial consortium experts are still confronted with inferior mechanical properties of fused weld interfaces in reality. Exemplary is early mechanical failure in patient-specific and biodegradable medical devices based on Corbion’s poly(lactides), and more technical constructs based on Mitsubishi’s poly(ethylene terephthalate), PET. The origin lies in contradictory low rate of polymer diffusion and entangling, and too high rate of crystallization that is needed to compensate insufficient entangling. Knowing that Zuyd University in close collaboration with Maastricht University has eliminated these contradictory time-scales for PLA-based systems, Corbion and Mitsubishi contacted Zuyd with the question to address and solve their problem. In previous research it has been shown that interfacial co-crystallization of alternating depositioned opposite stereo-specific PLA grades resulted in strengthening of the interface. To promote mass adoption of thermoplastics AM industries, the innovation question has been phrased as follows: What is a technically scalable route to induce toughness in additively manufactured thermoplastics? High mechanical performance translates into an intrinsic brittle to tough transition of stereocomplex reinforced AM products, focusing on fused deposition modeling. Taking the professional request on biocompatibility, engineering performance and scalability into account, the strategies in lowering the yield stress and/or increasing the network strength comprise (i) biobased and biocompatible plasticizers for stereocomplexed poly(lactide), (ii) interfacial co-crystallization of intrinsically tough polyester based materials formulations, and (iii) in-situ interfacial transesterification of recycled PET formulations.
The Hanzehogeschool Groningen (HUAS hereafter) is a University of Applied Sciences that is strongly inspired by the challenges of the North Netherlands region and firmly embedded in the city of Groningen in particular. HUAS has a strong track record in education, and practice-based research, and is dedicated to enhancing innovation and entrepreneurship. HUAS currently has 31,000 students Bachelor and Master students in 70 teaching programs. The 3.000 member of staff forming 17 schools and 7 centres of applied research collaborate to offer a cutting-edge teaching-based research. HUAS took the challenge to develop a strong research capacity with 67 professors, and an increasing number of researchers at various levels, supported by dedicated technical and administration support staff. PhD research thesis are co-supervised in collaboration with various universities in the Netherlands and abroad. HUAS positions itself as an Engaged and Versatile university, both in education and research. In line with this, the overall strategic ambitions of HUAS are to develop suitable learning pathways with recognised qualifications; to conduct applied research with a visible impact on education and society; and to be an adaptive, versatile and approachable organisation. HUAS links these strategic ambitions to three strategic research themes: Energy, Healthy Ageing and Entrepreneurship and four societal themes: strengthening a liveable and sustainable North Netherlands; transition to a healthy and active society; digital transformation; and energy transition and circularity. These four challenges define the focus of HUAS education and research.One of the societal themes is explicitly linked to the region: strengthening a liveable and sustainable North Netherlands. North Netherlands is a powerful, enterprising region with the city of Groningen as the healthiest city in the Netherlands. The region is a front runner in the energy transition, has a European exemplary role in the field of active and healthy ageing, and as an agricultural region, has many opportunities for the development of the circular economy and consequently the development of biobased construction material to mitigate climate change. Cooperation with different groups and stakeholders in the region is central in HUAS’s strategy. HUAS is part of extensive local and regional networks, including the University of the North and Akkoord van Groningen. As such, HUAS is well- connected to the research ecosystem in North Netherlands.HUAS has the ambition to better align, connect & develop on a local as well as a regional, national and international levels. Many of the challenges the North is faced with are also relevant in the EU context. Therefore, HUAS is a strong advocate and actor on engaging in European projects. HUAS monitors regularly the EU’s priorities and aligns its research between these priorities and its immediate societal needs. The EU provides a range of funding opportunities that fulfil our ambition as a research and teaching university and responds directly to our challenges from social, energy, and digital transformation. Indeed, over the last decade, HUAS has been successful in European programmes. In the Horizon 2020 programme, HUAS was part of five approved projects. In Horizon Europe so far two projects were granted. HUAS has performed particular well in the EU societal challenge for a secure, clean and efficient energy system. Examples of this are Making City (https://makingcity.eu/) focussing on the developing Positive Energy Districts, and IANOS (https://ianos.eu/) about the decarbonisation of islands. In addition to EU research and innovation schemes, HUAS has a considerable track record in projects funded by the Interreg schemes. In particular, these types of projects have strong links with region, and partners in the region. Currently, EU participation and involvement of HUAS is mainly concentrated in one field: sustainability & energy. In order to further disseminate to other parts of the university, only a well-designed strategy will allow the various research centres to better reach European fundings and satisfy the university’s ambitions. However, so far, no structured mechanism is in place internally to guide the research community and regional stakeholders how to reach European collaboration with confidence. Therefore, this pilot project aims to develop a strategic framework to enhance the participation of all parties at HUAS, including a pilot project that will lead to improvement and validation.
