Improving the energy efficiency of existing and new buildings is an important step towards achieving more sustainable environments. There are various methods for grading buildings that are required according to regulations in different places for green building certification. However, in new buildings, these rating systems are usually implemented at late design stages due to their complexity and lack of integration in the architectural design process, thus limiting the available options for improving their performance. In this paper, the model ENERGYui used for design and rating buildings in Israel is presented. One of its main advantages is that it can be used at any design stage, including the early ones. It requires information that is available at each stage only, as the additional necessary information is supplemented by the model. In this way, architects can design buildings in a way where they are aware of each design decision and its impact on their energy performance, while testing different design directions. ENERGYui rates the energy performance of each basic unit, as well as the entire building. The use of the model is demonstrated in two different scenarios: an office building in which basic architectural features such as form and orientation are tested from the very beginning, and a residential building in which the intervention focuses on its envelope, highlighting the possibilities of improving their design during the whole design process.

Carbon dioxide is the largest component of the human footprint and one of the major components of all greenhouse gases. The expected increase in population will lead to growth in energy consumption and greenhouse gas emissions. The building industry has the highest potential for reducing greenhouse gas emissions. Therefore, buildings should become not only efficient consumers but also energy producers, not a simple task in dense cities. The paper describes the feasibility and limitations of near zero energy design in highly dense urban conditions. The study was carried out by examination and comparison of various density design, alternatives of an existing urban plot in the coastal climate zone of Israel. Increased dwelling units’ number leads to higher total energy use on the one hand and mutual shading of new high-rise residential buildings on the other. Preserving solar rights for PV systems installation become more complex. The relation between urban density and solar rights in urban design, energy consumption and energy generation within plot borders and their implications are presented and discussed in the paper.

The performance of the built environment is an important concern affecting the quality of life and plays a critical role in every urban milieu. However, it generally disappears in the drawing plans. Current planning regulations do not always include performance requirements as part of the planning demands. Additionally, decision-makers lack the methodology and tools to demonstrate the expected performance of the built environment. Therefore, an examination of the performance of the designed area is sometimes neglected in the planning process. Current urban plans focus mainly on technical issues, counting the number of residential units, density measures, etc. The trend of progressive planning regulations, such as Form-Based Code (FBC), aims to coordinate these separated quantitative parameters into one comprehensive 3D plan where the urban form plays as a main integrator. However, these plans still lack the demand for understanding the quality and performance of the built environment through the visualization. This article addresses this gap, the lack of understanding of the performance of the built environment in urban plans and proposes the concept of Performance-Based Codes (PBC). The transition from form-based code to performance-based-design will be demonstrated through the presentation of two performance-based models, the Solar Envelope and Security Rating Index, and the possibility of integrating them into the planning process.

Reducing carbon emissions is one of the major challenges facing policy makers today. Cities need a better grasp of the effects of comprehensive energy retrofitting to deal with this crisis. In this study, an Energetic Profile for Existing Office Buildings concept and its features are presented. It consists of seven architectural parameters from macro to micro, including building environment, envelope, compactness, shape, floor plan flexibility and access to daylight, floor efficiency and space subdivision. The Energetic Profile identifies energy-saving opportunities and defines the key energetic-architectural typologies of office buildings that are rarely incorporated in environmentally conscious standards. For each parameter, a methodology is presented to calculate the total energy impact (cooling, heating, and lighting). This is illustrated by an assessment of a theoretical office building located in a hot and humid climate. The findings prove the effectiveness of the Energetic Profile in identifying energy savings, comparing design alternatives, and qualifying the influence of construction phases. Applications of the Energetic Profile to new office buildings are also discussed.

This paper presents an assessment and comparison of the effects of static and kinetic external shading elements on the dynamic measurement of daylighting. For this purpose, we used a method and parametric tool developed previously for the design and analysis of external shading elements in buildings. The proposed approach was used to compare static and dynamic movement scenarios for achieving optimal internal adjusted useful daylight illuminances (AUDI). The current paper presents the results of a methodical analysis, which compared various types of louvers in static and dynamic operation scenarios for a typical office in a Mediterranean climate. The results show that dynamically adjusted louvers perform notably better than fixed or seasonally adjusted modes of operation. The results show that dynamic operation scenarios can increase the AUDI by up to 51%. The results also show that in some conditions the existing rules of thumb fail to predict the correct design approach to louver geometry and that the use of rules of thumb in architectural daylight design needs to be revaluated.

The paper presents a new enumerative method and tool to quantify and compare the potential contribution of kinetic and static external shading elements in buildings, in terms of dynamic measurement of daylighting. The suggested method and tool may help designers to examine the impact of various louver design and operation alternatives in the early stages of the design process. It also allows comparing the potential contribution of different dynamic louver movement scenarios to internal illuminance. This can help designers to better evaluate and compare different dynamic systems, which can be more cost effective. The method and tool are tested on a case study of an office building in a Mediterranean climate, by calculating and comparing the values of useful daylight internal illuminances in static, seasonally adjusted and dynamic louver setup scenarios in comparison to those without louvers. The results of the case study illustrate the contribution of the suggested method and tool to designing for high useful daylight levels. The case study’s illuminance evaluation shows an increase of −1.82% to 7.99%, −1.4% to 11.67% and 10.86% to 33.6% in level of the adapted useful daylight illuminances in static, seasonally adjusted and dynamic external shadings scenarios correspondingly in comparison to the no external shading scenario.

In this chapter, readers can find a description of the design process and considerations that architects and engineers need to take when designing an intelligent envelope. The process is based, among others, on climate and location requirements. Passive and active strategies are contrasted. A description is given of the actions to be used when considering the focus on energy analysis, budget, etc. Note is made of the different procedures that have to be taken into account when designing a new or a retrofit building, with the main philosophy being that an intelligent element must be the product of a comprehensive intelligent design process.

The chapter provides an introduction to the subject, even though it assumes that readers are familiar with basic building physics’ concepts. It also presents specific definitions to the subject (intelligent, smart, responsive and adaptive) making it clear that the aim of the book has to do with energy-conscious design and architecture of intelligent building envelopes. Readers can find that the design philosophy of the book is that intelligence is not only a collection of smart devices and mechanical systems but the product of a careful architectural and informed design process .

This chapter illustrates the procedures for intelligent envelope design by analyzing two examples representing different initial scenarios, such as a new office building design and a residential energy retrofit. In this way, designers can study more clearly, through different situations, the steps essential for successful envelope design. The examples are developed through conceptual site analysis , showing the most suitable paths that follow appropriate energy strategies according to each case. In this way, it is possible to select sets of solutions for the envelope components according to design priorities.

Buildings represent about 40% of the total primary energy consumption and contribute approximately to one-third of the total greenhouse gas emissions. Green building standards and certification systems include requirements for both new and existing buildings. However, a vast part of the existing building stock in cities was built with limited consideration for green design, energy efficiency and low carbon emissions, yet its refurbishment can help reach national energy reduction goals, decreasing environmental impact. Furthermore, retrofitting existing buildings can often be more cost-effective than building new facilities. The potential of an existing building to achieve certification under a certain Green Standard, defined in this work as its Green Potential (GP), depends heavily on factors that were determined during the original design and construction process. This paper will present the development of a method and tool for the analysis and determination of the GP of existing buildings, allowing quick evaluation of a single building or the comparison of different buildings in order to understand their potential and limitations, both by designers before their intervention or by planning authorities as ways of determining development plans and retrofitting potential in cities and districts.

Climatic changes have increased the world-wide frequency of extreme weather events such as heat waves, cold spells, floods, storms and droughts. These extreme events potentially affect the health status of millions of people, increasing disease and death. Since mitigation of climate change is a long and complex process, emphasis has recently been placed on the measures required for adaptation. Although the principles underlying these measures are universal, preparedness plans and policies need to be tailored to local conditions. In this paper, we conducted a review of the literature on the possible health consequences of extreme weather events in Israel, where the conditions are characteristic of the Mediterranean region. Strong evidence indicates that the frequency and duration of several types of extreme weather events are increasing in the Mediterranean Basin, including Israel. We examined the public health policy implications for adaptation to climate change in the region, and proposed public health adaptation policy options. Preparedness for the public health impact of increased extreme weather events is still relatively limited and clear public health policies are urgently needed. These include improved early warning and monitoring systems, preparedness of the health system, educational programs and the living environment. Regional collaboration should be a priority.

This research explores a proposal for natural light restoration design for exhibition spaces in the Ein Harod Museum of Art. The original design and method of introducing daylight are described and their mechanisms depicted. The reasons for recent modifications, mostly due to conservation demands, and their impact on light quality are discussed. Owing to the Museum's unique design achievement and the worldwide influence on late twentieth century museum architecture, the research emphasizes the necessity for a light restoration project. The applied approach of introducing light also invites rethinking the current paradigm of using natural light in art exhibition spaces. Restoration objectives are determined and a design based on laser cut panels (LCPs) technology is proposed. Sets of experiments are presented: devising a LCP gable roof form geometry; analysing LCP daylight performance; and examining the original design. Finally, the performance of the proposed design is studied and is shown to be adequate for current conservation demands. Both quantitative and qualitative experimental methods were used: radiance light simulations, scale model measurements using photography, high-dynamic-range imaging photography (luminance levels) and HOBO data loggers. The findings propose integrating a louver system together with an LCP roof structure, a combination that restores daylight performance and preserves the quality and spirit of the original design.
