Low Budget Residential Building Façade Retrofit

Galit Shiff, Yael Gilad

Shenkar - Engineering. Design. Art., Israel

The residential market in the Mediterranean climate as well as in other parts of the world has a large number of buildings that were built with a long lasting structure but limited consideration for energy efficiency and thermal comfort. Retrofitting the existing envelope can help reach national energy reduction goals while improving the living conditions and reduce energy expenses for the tenants. This study focuses on low budget retrofitting of old residential buildings in a Mediterranean climate with two applicative case studies already finished. The two buildings are of similar size but in different local climate settings. In both projects a similar analysis methodology was performed, that included structural, thermal and energy use inquiry. The analysis concluded in intervention strategies for each building, and despite the similarity in the buildings, the variations in the intervention strategies were essential. This paper focuses on the methodology to analyse existing structures in order to identify preferred renovation tactics, based on the knowledge of the executed case studies. The study was done in collaboration with Israeli housing companies and is meant to serve as a pilot for larger renovation projects of existing residential building stock.

The applicability of passive cooling methods has been a recurring subject in architectural engineering science. The integration of these methods in architecture often requires feasibility studies and, in most cases, a deep knowledge of the climatic conditions is required to succeed in this task. The number of parameters to be evaluated will depend on the complexity of the cooling system, the physics involved and the context. This paper addresses the climatic applicability of convective and evaporative cooling systems in the context of United States (US) through the creation of a series of applicability maps deriving from processed climate data. This work is a revision of the climatic maps for downdraught cooling developed in Europe and in China with an extension to evaluate the opportunity for natural ventilation. More specifically, the studied cooling solutions are: Natural Convective Cooling (NCC), Passive Evaporative Cooling (PEC), and Active Downdraught Cooling (ADC). The maps obtained demonstrate the strong potential for the use of passive evaporative and convective cooling solutions in the US to overcome the current dependency on mechanical systems.

The 5 Degrees Forced Climate Refugees. Negative Carbon and Positive Energy Eco-cycle Housing Solutions.

Marwa Dabaieh

Malmö University, Sweden

Climate and weather severe events together with political conflicts linked to climate change are the most driving force for mass population to leave their homes seeking safe heavens. Climate refugees are becoming and will be the next wicked challenges we will face. Refugee temporary settlements proved to have high environmental burdens given their short life time using industrial materials with high embodied carbon in the production. Since long, alternative natural based low impact materials do exist using a carbon neutral production and construction process. This paper is presenting the outcome of one-year project in designing and constructing an eco-cycle negative carbon and positive energy eco-cycle home. The idea is to achieve a self-sufficient and low impact temporary shelter design with the least carbon emissions during construction and after demolition. The design complies with premium passive house standards constructed in an experimental urban living lab for proof of concept. The house now under monitoring for evaluating its performance. The project is applied in Sweden but the methodology could be applied in different other climatic contexts.


2:10pm - 2:20pm

Hybrid Adaptability: Zero-Emission Lifetime Homes in the Remote Rural

Neil Keith Burford1, Carol Robertson2

1Newcastle University, United Kingdom; 2University of Dundee

The cost of living rurally, already higher than urban areas in terms of food, transport and energy, is exacerbated by energy inefficient and inflexible homes, which has had detrimental impacts on the viability and sustainable growth of rural communities. Following on from community land buy-outs in the late 1990’s, the communities on the Island of Eigg and the Knoydart peninsula in the remote north west of Scotland have facilitated innovative measures which have been central to lowering their CO2 emissions and maintaining the viability of their off-grid locations. Central to Eigg’s strategy has been the implementation of a world-first zero-emission grid combining LZCGTs, battery storage and smart controls, telecommunications networks and shared equity land policies to encourage self-build housing. Notwithstanding, there is a lack of appropriate community-led, affordable, adaptable, grid-integrated housing models which remains a significant barrier to encouraging new people to move into the community to ensure its long-term resilience. The following paper discusses parameters for the design of alternative hybrid zero-emission housing typologies that have the capacity to cater for varied tenures and lifestyles, including live-work and rentable space, providing lifetime homes and energy balancing scenarios through their in-built flexibility.
