AbstractEver growing building energy consumption requires advanced automation and monitoring solutions in order to improve building energy efficiency. Furthermore, aggregation of building automation data, similarly to industrial scenarios allows for condition monitoring and fault diagnostics of the Heating, Ventilations and Air Conditioning (HVAC) system. For existing buildings, the commissioned SCADA solutions provide historical trends, alarms management and setpoint curve adjustments, which are essential features for facility management personnel. The development in Internet of Things (IoT) and Industry 4.0, as well as software microservices enables higher system integration, data analytics and rich visualization to be integrated into the existing infrastructure. This paper presents the implementation of a technology stack, which can be used as a framework for improving existing and new building automation systems by increasing interconnection and integrating data analytics solutions. The implementation solution is realized and evaluated for a nearly zero energy building, as a case study.

The concern regarding local responsive building design has gained more attention globally as of late. This is due to the issue of the rapid increase in energy consumption in buildings for the purpose of heating and cooling. This has become a crucial issue in educational buildings and especially in schools. The major issue in school buildings in Saudi Arabia is that they are a form of prototype school building design (PSBD). As a result, if there is any concern in the design stage and in relation to the selection of building materials, this will spread throughout the region. In addition to that, the design is repeated regardless of the climate variation within the kingdom of Saudi Arabia. This research will focus on the influence of the window to wall ratio on the energy load in various orientations and different climatic regions. The research will use the energy computer tool TAS Environmental Design Solution Limited (EDSL) to calculate the energy load as well as solar gain. During the visit to the sample schools, a globe thermometer will be used to monitor the globe temperature in the classrooms. This research introduces a framework to assist architects and engineers in selecting the proper window to wall ratio (WWR) in each direction within the same building based on adequate natural light with a minimum reliance on energy load. For ultimate WWR for energy performance and daylight, the WWR should range from 20% to 30%, depending on orientation, in order to provide the optimal daylight factor combined with building energy efficiency. This ratio can be slightly greater in higher altitude locations.

Abstract- Many of high-rise office buildings in Indonesia applies efficiency and effectivity of building form,cost, and time for construction as a number one priority. As a result, high-rise office buildings appears with aminimum-articulated form, and show the dominance by using glass materials as a facade. However, there arealso high-rise office buildings that have an articulated form and its facades that are not dominated by glass,although they appear in small numbers. Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabayaare one of them. Moreover, both buildings were designed by foreign architect, Paul Rudolph. Based on thepotentials of both buildings, this research focused on Paul Rudolph’s principles in designing high-rise officebuildings in Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti SurabayaLooking at the phenomena of high-rise office buildings in Indonesia as described earlier, this smallnumber and the articulated form of high-rise office buildings designed by Paul Rudolph in Indonesia areinteresting to be understood even more. The main purpose of this research is to reveal the relationship betweenPaul Rudolph’s design principles with buildings, which are Wisma Dharmala Sakti Jakarta and WismaDharmala Sakti Surabaya.Using an interpretative method in a qualitative research, this research utilized theories that helpsunderstanding of an office building, theories that related to Paul Rudolph’s background and common thoughtabout architecture, and also Paul Rudolph’s theory about determinants of architectural form as a literaturestudy. Building’s Anatomy Theory is used as a surgical tool to disect the study cases, which happens to beWisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya.Result of this research are six points of Paul Rudolph’s principles in designing high-rise office buildingwhich are: repetition, space, scale, rotation, light, and context. Implementation of Paul Rudolph’s designprinciples in both study cases can be seen in the dominance of rotation and repetition of building elements. Theapplication of these two principles can fulfill all the three aspects of Paul Rudolph’s design ideal, which areform, context, and cycle.Benefit of this research is to enrich architectural vocabulary about design principles of a high-riseoffice buildings in Indonesia for the concerned educational institution, as a consideration and input toarchitects and the stakeholders to be more sensitive and critical in designing high-rise buildings in Indonesia,as a reference and study case about design principles of a high-rise office buildings for students, academics,architects, and the public with the focus of study concerned, and enrich the knowledge about Paul Rudolph’sdesign principles especially in designing high-rise office buildings in Indonesia for researcher.Keywords: Paul Rudolph, Design Principles, Office, Wisma Dharmala Sakti Jakarta, Wisma Dharmala SaktiSurabaya.

Energy Efficient Building

Energy efficiency of buildings, of course, is now a major issue in the construction industry. It is being widely examined both among construction professionals and amateurs. There is no doubt that energy efficiency as a key factor in ensuring environmental sustainability will become the main driving force of the construction in the future. Buildings have to become more energy-efficient. This opinion is supported by the existing energy-use balance in Europe, indicating that the housing sector spends almost half of total energy consumption and building sector forms more than a third of total CO2 emissions (Bradley 2010). While discussing the subject of building energy efficiency, mostly different technical characteristics of buildings and engineering solutions are talked over. However, it has been relatively little examined how energy-efficient design affects the building’s architecturally-aesthetic side, styles of expression and trends in the architect’s profession. We learn that the essence for an energy-efficient building lies in smart modesty (Bokalders, Block 2010) and the rational utilization of materials (aim high – go low). And still – can energy efficient building be expressive, extravagant, and perhaps – even ambitious? There are many ideas implemented in projects which show that energy efficiency is not an obstacle to large scale architectural ideas. However, in order to combine architectural and artistic ambitions with the principles of sustainability, architects should search for an entirely new approach to architectural expression based on a detailed assessment of solutions applied from environmental point of view. It requires a complex understanding of building shape, applied technologies, energetic benefits and cost parameters. This article identifies the realised and experimental projects of the world and presents an analysis of classification of buildings according to typology. This publication gives general impression of the amplitude and topicality of the study issue, as well as the diversity applied to the architectural techniques. The article concludes that even creating a building’s shape in a smart way makes it possible to use substantial part of the renewable energy offered by nature.

Objective Being

In Nigeria, there is an estimated deficit of 17 million housing units. Power supply is insufficient, and the electricity supply for about 60 million Nigerians relies on private generators, causing noise, pollution, and high expenditures for mainly imported fuel. Altogether, current challenges clearly demonstrate the need for effective energy efficiency policies targeting also the building sector. The Nigerian Energy Support Program began in 2013, among others, with the objective being to support the Nigerian Government in developing the Nigerian Building Energy Efficiency Code. This paper presents two preparatory activities carried out in order to come up with suggestions for a legal framework well suited for the situation on the ground: the Case Study Building Analysis carried out in collaboration with a Nigerian developer and the Nigerian Building Energy Efficiency Guideline, elaborated together with stakeholders. The results of preparatory activities pointed out that the code must put emphasis on climate adaptive design and must define requirements and procedures in a clear and simple way to allow for effective enforcement. Only then can energy-efficient mass housing be feasible in Nigeria. The paper concludes with a description of the Nigerian Building Energy Efficiency Code (BEEC), officially approved and launched by the Federal Minister of Power, Works and Housing on 29 August 2017.

Architectural Design Education

Most CAAD software in use for architectural education relies heavily on abstract geometry manipulation to create architectural form. Building materials are usually applied as finishing textures to complement the visual effect of the geometry. This paper investigates the limitations of commonly used CAAD software in terms of encouraging an intuitive thinking about the physical characteristics of building materials in the context of the educational design studio. The importance of the link between representation and creativity is noted. In order to sample the current functionality of typical software used in architectural education a case study involving 80 first year architecture students is presented. These outcomes are discussed and the possibility for new or extended software features are suggested. The paper concludes with an argument for design software that redresses the balance between geometry and materials in architectural design education.

Stability Of Plant Communities

The relationship between diversity and stability is a classic issue in ecology, but no general consensus has been achieved. To address this relationship, a field survey of a forest in Northeast China was conducted. The temporary stability was defined from the perspective of community characteristics. The results showed that communities with the highest temporary stability value were characterized by a single dominant species. A significant linear relationship with a low R2 value was observed between temporary stability and tree richness. When dominant and non-dominant tree species were studied, no significant linear relationship was obtained between temporary stability and non-dominant tree richness. However, the relationship between temporary stability and dominant tree richness was significant with a high R2 value, and the temporary stability decreased with increasing dominant tree richness. This study demonstrates that dominant tree richness is closely related to temporary stability, and temporary stability can serve as a stability indicator. The results provide a new perspective for understanding stability and additional information for revealing the relationship between diversity and stability in forest ecosystems.
