In 2017 the Danish Building and Property Agency started a project titled “Avoiding energy waste in ventilation systems” by tracking the actual energy use in a sample of their 4 million m2 portfolio of buildings through on-line energy management tools. The project is not complete, but the key preliminary findings  described in this paper are: 

Thermal comfort improvement at the lowest energy consumption is a key issue when dealing with sustainability in buildings. An appropriate passive design is mandatory under those circumstances. Prior to construction, simulation tools help to make designs more sustainable. However, it is recognized a gap between real performance and the predicted one. This article presents the comfort methodology applied in an office building located in the north of Spain, characterized by a continental Mediterranean climate.

Over the last three years the understanding, adoption and use of BIM has gained international momentum.

In Portugal, the external thermal insulation systems (ETIS) are nowadays a current technical solution in residential buildings, contrasting with the rarely used internal thermal insulation systems (ITIS). In this paper, a quantitative analysis on ITIS is done based on three hygrothermal façade requirements: interstitial condensations, thermal bridges, and temperature variations across the external wall. Computer simulation was used as research tool.

Life Cycle Assessment (LCA) in many ways is a methodology which building industry is looking towardsto give the answers on how to assess sustainability of buildings. In Hong Kong, like many othercountries, its application is limited by the availability of credible assessment tools in the market. Thispaper provides the details on the processes and findings of a comprehensive study initiated by theGovernment to derive a LCA tool for the use of the local building industry, addressing on researches thatare needed to really make LCA part of the answer to sustainability assessment.

1. Thoughts 1. Why care? 2. Sustainable Architecture or just Architecture, are they something different? 3. On past and future – learning from tradition. 4. On the overwhelming power of design. 5. On starchitecture. 6. On the design process and the golden

SERRAGLAZE is a breakthrough daylighting system designed to be incorporated into the primary glazing of normal sidelit rooms to save energy and enhance comfort.The paper describes the design, construction and optical properties of the plastic SERRAGLAZE panel, the key component of the system.
