Environmental analysis of residential building facades through energy consumption, GHG emissions and costs

This paper provides some results on the potential to minimize environmental impacts in residential buildings life cycle, through façade design strategies, analyzing also their impact on costs from a lifecycle perspective. On one hand, it assesses the environmental damage produced by the materials of the building envelope, and on the other, the benefits they offer in terms of habitability and liveability in the use phase. The analysis includes several design parameters used both for rehabilitation of existing facades, as for new facades, trying to cover various determinants and proposing project alternatives. With this study we intended to contribute to address the energy challenges for the coming years, trying also to propose pathways for innovative solutions for the building envelope.

Facade typologies as a tool for selecting refurbishment measures for the Spanish residential building stock

Today, the building sector alone accounts for 40% of the total energy consumption in the European Union (EU). In most EU member states, about 70–90% of the buildings were constructed at least 20 years ago. Due to this, these buildings have a worse energy efficiency behavior than the new ones that comply with current regulations. As a consequence, acting on the existing building stock is needed, developing special methods on assessment and advice in order to reduce the total energy consumption. This article addresses a procedure allowing the classification and characterization of existing buildings facades. It can help researchers to achieve in-depth knowledge of the facades construction and therefore knowing their thermal behavior. Once knowing that, the most appropriate upgrading strategies can be established with the purpose of reducing the energy demand. Furthermore, the classified facade typologies have been verified, complying with current and future Spanish regulations and according to the results obtained, a series of upgrading strategies based on the opaque part and those in the translucent part, have been proposed. As a conclusion, this procedure helps us to select the most appropriate improvement measures for each type of facade in order to comply with current and future Spanish regulations. This proposed method has been tested in a specific neighborhood of Madrid, in a selected period of time, between 1950 and 1980, but it could be applicable to any other city.

Energy and economic survey of the renovation of a residential building wall in Madrid

La edificación es un sector de enorme influencia en la evolución del consumo de energía y las emisiones de CO2. Teniendo en cuenta que en estos momentos hay 3,5 millones de viviendas vacías y que los próximos años no va a haber un aumento en la demanda de vivienda nueva, la rehabilitación sostenible del parque residencial existente es una tarea prioritaria y sobre la que hay que prestar especial interés. Dado que aún queda mucho donde actuar, es necesario hacer una reflexión sobre cómo se está rehabilitando para poder mejorar en el futuro. Por ello, el objetivo del presente trabajo es analizar algunas estrategias adoptadas hasta ahora en el parque inmobiliario y su aplicación en un caso de estudio, mediante la mejora de la fachada de un edificio de viviendas situado en Madrid.

Social Indicators in the Sustainable Refurbishment: Calculating Quality of Life Indicator in a Residential Building in Málaga

How can we measure ‘quality of life’? The sustainable refurbishment goes beyond strictly energy aspects. Sustainability indicators are needed to facilitate data collection and to provide information which does not require too time-consuming calculations. Thus, you can offer an idea of the extent and quality of the rehabilitation before starting the project and, also, the obtained results can be evaluated in an agile way after the refurbishment. From a list of social indicators gathered from different methods, sustainability assessment tools and International and European standards, three social indicators are proposed: Users Satisfaction, Participation Agreement and Quality of Life. This paper shows the development of Quality of Life social indicator, the more closely related to the main objectives of Researchand Development Project “Sustainable Refurbishment”: improving energy efficiency and wellbeing of users in existing residential buildings. Finally, this social indicator is applied to a real case study in Málaga (Spain).

Cross Ventilation CFD Modeling: Characterization and Study of Different Façade Openings Configurations at the Refurbishment of a Residential Building in Málaga (Spain)

The opening of new windows on the façade is proposed as a refurbishment strategy in an existing building in Málaga to facilitate cross ventilation of dwellings. The building is a residential block of 140 public housing units for rent for people with low income in Málaga (Spain), property of the City Council. By modeling with Computational Fluid Dynamics (CFD), eleven configurations of openings are studied in two different areas of the main housing type of the building. The quantity of introduced/extracted air into/from the room and the generated airflow patterns are obtained. The modeling allows comparing the different openings configurations to determine the most appropriate ventilation option for every room.

Kit-of-parts architecture : an exploration into the standardization and simplification of an urban residential building unit

This thesis focuses on the design of a construction method that utilizes a single adaptable kit-of-parts system. The new system is designed to be flexible while also enhancing construction speeds without severely limiting the building's ability to merge into an urban fabric. This thesis proposes a residential structure to be built from a handful of simple structural units. This is accomplished through the design of a residential building situated in an area of Miami currently under reconstruction.

Hoe beïnvloeden de marktkenmerken de belemmeringen voor innovatie in de utiliteitsbouw in Nederland?

How do the market characteristics influence the obstacles to innovation in the non-residential building industry in the Netherlands? Innovation can make an important contribution to the firm’s competitive advantage. Within the nonresidential building industry in the Netherlands the competition is very high. Therefore there should be enough motivation to innovate. The building industry has been severely hit by the economic crisis in the past years in the Netherlands, which made the competition even harder. Nevertheless the industry has a poor reputation on innovation and is known as a conservative industry. In the past decade the industry and government have put a lot of effort into making the sector more innovative. Sadly the innovation level has hardly improved. Why does the building industry fail to make itself more innovative? To make a contribution to this issue a research can be conducted to investigate the causes of this low innovation level. Research This thesis tends to make more clear about the causes of the low innovation level. Based on an extensive field research as well as a literature research the main question of this thesis is: How do the market characteristics influence the obstacles to innovation in the non-residential building industry in the Netherlands? The structure is based on qualitative research through case study research. Therefore a conceptual model is structured which is used as a fundamental base. Within the first case 21 interviews were held with the prime actors which played a direct role in the innovation level of non-residential projects. These prime actors are clients, consultancy agencies and building contractors. Also two panel discussions were organized to discuss the outcomes of the interviews. In the second and third case a part of certain market characteristics of the conceptual model were changed. The main reason to investigate these cases is to substantiate the results of the first case.
