- Monitoring of a Double Skin Façade Building: Methodology and Office Thermal and Energy PerformancePublication . Marques da Silva, F.; Duarte, Rogério; Cardoso e Cunha, L.This paper concerns to the post-occupancy monitoring of a building sited in Lisbon with transparent double-skin façades. This is the first of an enlarged monitoring program covering other buildings and weather conditions, aiming to clarify under which climate and performing conditions this architectural solution is acceptable. Within this campaign an enlarged set of parameters was measured from external conditions to energy consumption and indoor comfort. The present paper describes the building, presents the monitoring methodology and analyses the thermal and energy performance of a specific office space.
- Glazing-related problems due to high temperatures in double skin façadesPublication . Duarte, Rogério; Leandro, S. Oliveira; Teixeira, A. Rego; Bigode, C.The thermal behaviour of a double skin façade building is modelled using the DOE-2 building energy simulation program. Maximum temperatures of glazed components of the double skin façade are determined to assess the occurrence of glazing-related problems, such as reduced thermal and aesthetic performance, increased maintenance costs and even injury hazards. The importance of detailed thermal modelling of double skin façades and of its glazed componentes is concluded.
- Avaliação energética de um sistema híbrido radiante-convectivo a dois-tubos, ventiloconvectores e paredes radiantesPublication . Roriz, L.; Duarte, Rogério; Gamboa, M.A comparação dos sistemas radiantes com os sistemas convectivos tradicionais pode ser efectuada através da análise comparativa dos efeitos resultantes da elevação da temperatura radiante média e 1 K com os efeitos resultantes da elevação da temperatura do ar interior de 1 K. No presente artigo, introduz-se um sistema híbrido radiante-convectivo baseado no sistema a dois-tubos, ventiloconvectores e paredes radiantes para um edifício de escritórios. Com base no programa de simulação DOE2, obtém-se a poupança energética anual devida à alteração da temperatura do ar no interior da sala de 1 K nas estações de aquecimento e arrefecimento e apresentam-se resultados que demonstram que o consumo energético para a alteração de 1 K da temperatura radiante média é inferior a esta poupança energética. Discutem-se questões técnicas e relativas ao investimento necessário para implementar o sistema híbrido radiante-convectivo. Os resultados permitem concluir o interesse deste sistema híbrido radiante-convectivo.
- Energy Benchmarking of Double-Skin Façade BuildingsPublication . Duarte, Rogério; Matos, M. deThis paper describes ongoing energy benchmarking studies of double-skin façade buildings. Benchmarking methodology is discussed. Some preliminary results are presented.
- On the Typology, Costs, Energy Performance, Environmental Quality and Operational Characteristics of Double Skin Façades in European BuildingsPublication . Streicher, Wolfgang; Heimrath, Richard; Hengsberger, Herwig; Mach, Thomas; Waldnere, Reinhard; Flamantf, Gilles; Loncourg, Xavier; Guarracinoh, Gérard; Erhorni, Hans; Erhorn-Kluttigj, Heike; Santamourisk, Matheos; Faroul, Ifigenia; Zerefosm, S.; Assimakopoulosn, M.; Duarte, Rogério; Blomsterbergp, Åke; Sjöbergq, Lars; Blomquistr, ChristerThe project BESTFAÇADE, sponsored by the Energy Intelligent Europe programme of the European Union, and led by MCE-Anlagenbau, Austria, accumulated the state of the art of double skin façades (DSFs) in seven European countries (Austria, Belgium, France, Germany, Greece, Portugal and Sweden). Twenty-eight façades of different buildings in all partner countries of BESTFAÇADE have been analysed for the aspects, types of façade in different countries, DSFs in different climatic regions of Europe, existing simulations and measurements, thermal behaviour, indoor air quality, comfort, user acceptance, energy demand and consumptions, control strategies, integrated building technology, cost (investment, maintenance and operation), resource conservation, environmental impact, comparison to conventional glass façades (CGFs), integration of renewable energy sources into DSFs, as well as non-energy related issues, such as, acoustics, aesthetics, fire protection, moisture, corrosion, durability, maintenance and repair. Most of the buildings are office buildings, followed by schools and service buildings. Nearly all of the buildings have mechanical ventilation systems, and both heating and cooling are performed mostly by air heating/cooling systems. The types of façades are mainly multi-storey and corridor types; in Belgium juxtaposed modules are frequently used. The façade gaps are mostly naturally ventilated (except for Belgium, where the indoor air is led by mechanical ventilation via the gap to the centralized air handling unit). The shading is performed mainly with Venetian blinds located in the gap. Unfortunately data on energy demand and temperatures are infrequently measured and rarely available. The cost of DSFs is significantly higher than conventional façades.
- A comparison between energy performance of one DSF buildings studied sample and office buildings benchmarks in EuropePublication . Matos, M. de; Duarte, RogérioThis paper describes ongoing energy benchmarks studies of double-skin façade buildings. A comparison between energy performance of these actual buildings and European office buildings benchmarks is discussed. Some preliminary results are presented.
