Although the interrelations between urban microclimates and energy demand have been acknowledged, few workflows integrate microclimatic boundary conditions to predict energy demand in parametric morphological studies. This paper helps bridge this gap by introducing a novel workflow which brings together energy and microclimatic modelling for a synergetic assessment at the block scale. The interrelation between form, energy and urban microclimatic conditions is explored here in the climatic context of Tel Aviv by coupling Envimet and EnergyPlus. The potential of this coupling is explored in three different block typologies, each tested for four different density scenarios focusing on the cooling demand on a typical hot day. Results show the substantial increase of as high as 50% in cooling demand when the microclimatic weather data is taken into account and indicate the potential to capitalize on new computational tools which allow to quantify the interrelations between urban form, microclimate and energy performance more accurately.

The integration of decentralised building services into façade components presents advantages from functional and constructional standpoints. However, this integrated approach has not been massively implemented, having only stand-alone buildings and façade concepts as examples. This paper seeks to identify the main perceived problems at design, production and assembly stages of the facade development process, to generate new knowledge based on practical experience; and to discuss the perceived barriers to overcome in order to promote widespread building service integration in façade systems. The employed method was an exploratory survey addressed to professionals with practical experience in the development of façade systems for office buildings, situated at any stage of the process. The survey was conducted from mid-September to mid-November 2015 and was distributed both as an online form and in printed format among several professional and research networks related with façade design and construction. After the campaign, 133 questionnaires were received, comprising a final number of 79 valid questionnaires. Results show that the main problems of the overall process are related to coordination issues among different disciplines and stakeholders, while other problems such as costs and lack of knowledge have more impact on particular stages within the design and construction process.
