Autarki Pavillion - Energy Monitoring and Analysis

The project, developed by CINARK, is an experiment, meant to generate, through a small pavilion, a discussion on wood, manufacturing, comfort and sustainability. The new envelope concept, developed by Jesper Nielsen, uses CLT panels, a material with inherent sustainable properties. Another feature of the building is the use of an "air heat exchanger" that works without the use of energy. Our part in the experiment is the understanding of the pavilion performance. By collecting on-site data and performing physical and digital variations of the building, we are defining ways to create an almost zero energy building with no active systems.

Learning from Functionalist Nordic Houses towards Passive, Active, Adaptable and Prefabricated Homes

This research presents a preliminary exploration to the definition of sustainable Nordic housing by appraising the qualities of four functionalist projects built prior to the energy crisis of the 1970s and four projects built after the year 2000, when sustainable design became an explicit target. The functionalist projects are: Erskine’s Box, Aalto's Helsinki House, Jacobsen's, Gotfred Rodes vej House, and Korsmo's Planetveien House. The recent case studies selected are: AART Architects’ Home for Life, Henning Larsen’s Adaptable House, Rune’s Tind Prefabricated House and Kaminsky Architecture’s Villa Nyborg. The performance in terms of environmental sustainable design of the case studies selected are studued qualitatively and quantitatively considering climate, context, form, structure, materials, and architectural programme. Site visits, literature review, and computer simulation of daylight distribution, operational energy, and embodied energy are analyzed. The study revealed that traditional projects encompass a stimulating concept of comfort. In more recent projects, higher performance are the drivers of the design.

Energy Refurbishment of Baserris. Modelling Users' Scenarious

The energy efficient adaptation of a historic building to future user scenarios is discussed with the case of baserris, the typical Basque farm. Following the industrial revolution several baserris were abandoned as the inhabitants moved to the cities. Today, there is a necessity in repopulating the baserris with a series of contemporary users' scenarios. The few examples of retrofitted baserris is based on the simplistic approach proposed by regulations, or standards such as the EnerPHit. The paper describes the hypothesis of an energy and culture balanced retrofit that sustains the adaptation to contemporary uses based on the understanding of a baserri thermodynamic behavior. The baserris as conceived in the XVth century and onwards are an example of an energy self-sufficient thermodynamic system that capitalize internal heat loads generated by agricultural production systems. Energy stored by the thermal mass is a critical aspect of their function which is undermined by according to code interventions. This paper explores a balanced retrofit that complements future user scenarios' thermodynamic implications and fabric interventions.

A Unified Tool to Design and Define Architectural Sustainability 2.0

The toolkit proposed here is meant to support conceptual design as well as the analysis of existing buildings. It is aimed to analyze the process, products, and principles of sustainability by using a user-friendly and sketch-based toolkit: a sustainable design storytelling, a multi-scale matrix, based on the hard and soft aspects of sustainability, and an environmental section. The storytelling is a powerful time-based tool that graphically defines the “moments” that determine the sustainable design. The matrix, inspired by the Living Building Challenge standard, allows to both plan and assess the identification of sustainable design ideals inspiring project teams to reach decisions based on restorative principles. Asymmetries in the matrix show strengths and weaknesses of a project according to a holistic definition of sustainability. Finally, the environmental section visually and creatively shows the invisible flows of sustainability that go beyond the classic sections used in architectural practices to represent sustainability. They also demonstrate where quantitative and qualitative flows of sustainability overlap, thereby illustrating how design engages users and nature at the local and the global scale.

The performances of Opaque Ventilated Facade

The optimization of buildings’ envelope thermal performances is a key factor in pursuing energy savings and thermal comfort. The Opaque Ventilated Façade (OVF) is a system that in recent decades has been increasingly used, especially for the thermal rehabilitation of existing buildings. Its overall performance, as shown in previous research, can impact the thermodynamics of a building. However, there is no clear understanding of its thermal efficiency in different types of climate. The research questions of the present study are the following: For which types of climate does the OVF contribute in reducing heating and cooling loads? For what type of building is it more efficient (commercial or residential)? How do OVFs design variables (such as, width of the ventilation channel (cavity), type of materials, size of joints among tiles and operations of the cavity - seasonally opened and closed) impact energy performance? With a parametric energy simulation study, several variations of OVFs are applied to a “shoebox” located in four European climatic zones. The effective use of the technology is described, as well as the design principles that could lead to climate base customization of the design.

Performance-based design strategy to improve the sustainability of buildings. A comparison of simulation workflows.

In architectural design field, performance-based design is redefined as “performative design”, i.e. performance-based generative design. It consists in a design process in which analytical evaluation is integrated with form generation. This approach was supported by the development of several design methods and tools, but none of them can support the hierarchical dimension of the building or the diachronic dimension of the design process. In order to implement this methodology, many methods and tools have to be considered. This research is concerned with the proposal and implementation of an appropriate design strategy to overcome the problem of integrating different tools and methods in performative design with the purpose of improving the energy performance of buildings.
