“…According to Schmidt et al (2004), in a typical application, the in use savings from insulation are over 100 times the embodied impact of production and disposal. In contrast, Harris (1999) claims that when the thickness of loft insulation is increased beyond 200mm, the embodied energy threatens to outweigh the operational energy savings. Weir and Muneer (1998) found modern glazing systems have a particularly high embodied energy up to 1500 kWh/m 2 , which could take 10 30 years to provide a positive energy contribution.…”

“…According to Harris (1999), there is a significant lack of studies concerning the actual embodied energy within refurbishments, particularly those measures designed for energy efficiency. According to Schmidt et al (2004), in a typical application, the in use savings from insulation are over 100 times the embodied impact of production and disposal.…”

Domestic UK retrofit challenge: Barriers, incentives and current performance leading into the Green Deal

This paper reviews the thermal performance of the existing UK housing stock, the main fabric efficiency incentive schemes and the barriers to obtaining deep energy and CO 2 savings throughout the stock. The UK faces a major challenge to improve the thermal performance of its existing housing stock. Millions of dwellings possess 'hard to treat' solid walls and have glazing which is not cost effective to improve. A range of fabric efficiency incentive schemes exist, but many do not target the full range of private and social housing. From now on, the Green Deal will be the UK's key energy efficiency policy. However, the scheme is forecasted to have low consumer appeal and low incentives for investors. Moreover, calculated Green Deal loan repayments will be reliant upon estimated energy savings, yet it is claimed that retrofit measures may only be half as effective as anticipated due to a lack of monitoring, poor quality installation and the increased use of heating following refurbishment. Looking to Germany, there has been success through the Passivhaus standard, but the UK currently lacks appropriate skills and cost effective components to replicate this approach. In addition, the embodied energy in retrofit products and materials threatens to counter operational savings.

Ceramics offer exceptional properties as an energy-efficient building material, but have rarely been investigated alongside active environmental performance. Responding to light-control criteria, we work with advanced digital modelling, fabrication and performance simulation tools to craft experimental full-scale ceramic prototypes of architectural daylighting components. Our research has three main goals: to investigate alternative daylighting technology solutions made of a low-impact material such as clay; to explore design methodologies that look into how current architectural ceramics manufacturing can be enhanced by emergent design and fabrication technologies; and to engage with the materiality of the clay through collaborative working with recognised artists and ceramicists. A critical aspect of our research is to test the compatibility and interoperability of different software and design techniques, as phases of the production process (optimisation of form finding) in real time. This paper presents the development, construction and analytical data of three of the experimental production methods developed during the first three years of this project.Keywords: architectural components; ceramics; digital fabrication; daylighting; craftsmanship. RESUMEN El material cerámico ofrece excelentes oportunidades como material de construcción energéticamente eficiente, sin embargo sus propiedades se han investigado muy escasamente en combinación con un comportamiento medioambiental activo. Respondiendo a criterios de optimización de la iluminación natural, trabajamos con procesos paramétricos digitales de fabricación, así como con herramientas de simulación energética para confeccionar prototipos experimentales a escala real de componentes arquitectónicos cerámicos. Nuestra investigación tiene tres objetivos principales: explorar soluciones para la optimización en el uso de la luz natural fabricadas con un material de bajo impacto como la cerámica; investigar metodologías proyectuales que miren a cómo los procesos de producción arquitectónica cerámica actuales pueden mejorarse gracias a la incorporación de técnicas digitales de fabricación y diseño, y comprometernos con la materialidad de la cerá-mica a través de trabajo en colaboración con artistas y técnicas artesanales. Un aspecto crítico de nuestro trabajo es probar la compatibilidad e interoperabilidad de diferentes plataformas informáticas y técnicas de diseño como fases del proceso de producción (optimización de la búsqueda de forma) en tiempo real. Este artículo presenta el desarrollo, construcción y resultados analíticos de tres de los métodos de producción experimentados durante los tres primeros años de este proyecto.

“…When highly developed nations and low-income countries are compared, it is indicated that low-income countries usually have less efficient processes that will require more energy and at the same time produce (Buchanan, 1994;Harris, 1999;Emmanuel, 2004;Asif et al, 2007).…”

“…Considering such factors, it becomes quite impossible to use the same values of energy consumption and/ or environmental impacts for a given material in different contexts. Harris (1999) building's overall resource efficiency. To its addition, Buchanan and Honey (1994) consider that, among the various greenhouse gases emitted by human activities, CO 2 is the most important by-product of the manufacturing of building materials.…”
