Test Result

Computer simulation is an important and proven method to help understand and analyze the thermal performance of buildings, and predict their operational energy consumption. Building energy simulation is widely used to help design energy efficient building envelopes and HVAC systems, develop and demonstrate compliance of building energy codes, and implement building energy rating programs. However, large discrepancies exist between simulation results from different building energy modeling programs. This leads many common users lack confidence in the results from building simulation methods.

Energy Efficient Building

Shortage of green skills has become a major constraint to energy efficient building programs and policies of Malaysia and many Asian countries. Yet, studies aimed at green skills are rare. Relying on an online survey of 99 professionals accredited by the Malaysian Green Building Index (GBI) this study seeks to: [1] identify the necessary green skills required for design and delivery of energy efficient building; and [2] identify and capture areas of skill gaps based on available and future green skills needs. Our preliminary result reveals that generally, available energy efficient green skills in Malaysia are below average. The highest skill gaps were found to be in the areas of energy efficiency maintenance for HVAC system, competence in use of diagnostic tools to measure building energy efficiency, carbon storage and capture in buildings and competency of architects/ builders in passive designs and installation.

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.

Energy Efficient Building

In the present study a GUI tool for the prediction of building energy performance based on a three-layered BP neural network and MATLAB was developed. The inputs for this tool are the 18 building envelope parameters. The outputs are building heating, cooling and total energy consumptions and the energy saving rate. Compared with the complicated mathematical equations, this tool provides a very easy and effective method for students to learn the effects of building envelope performance parameters on the building energy performance. Thus, this tool can be used in building physics and building energy efficiency courses for the design of energy efficient building.

Energy Efficient Building

The principles of building energy simulation and its relationship with heating and cooling energy calculation help to make an integrated evaluation of building energy consumption. This is used to achieve a better and more energy efficient building. The sensitivity analysis of energy efficient HVAC design was used to create an energy efficient Peel Region Headquarters Building. An energy audit was conducted on the existing building to establish the Base Case Model "Peel Region Headquarters Building" to determine its annual energy consumption across all current usage. To reduce the total energy cost of the Base Case Model, different HVAC Systmes were investigated to analyze their energy-based performance and impact on the Greehouse Gas Emission (GHG). The sensitivity analysis was conducted using two whole building simulation programs, "Carrier HAP" and "eQUEST", with three different air systems, namely, "2-Fan Dual Duct Variable Air Volume System", "1-Fan Dual Duct Variable Air Volume System" and "1-Fan Dual Duct Variable Air Volume System with two Rooftop Packaged HVAC System'. Three different types of heat pumps, namely, Open Loop Water Source Heat Pump, Closed Loop Water Source Heat Pump, and Ground Source Heat Pump, were used to determine the efficiency and viability of the three proposed HVAC System with the existing infrastructure. RETScreen International Clean Energy Project Analysis Software (Version 4) was used to evaluate the energy production and savings, life-cycle costs, emission reductions and financial viability. MNECB/CBIP and ASHRAE 90.1 (2004) Building Compliance Program was used for determining the key elements for analyzing the building components and for providing recommendations for an energy efficient building. The improvement from the conventional HVAC System to implementation of an Open Loop Water Source Heat Pump resulted in 75% energy cost savings for the Peel Region Headquarters Building. The percentage contribution of CO₂ was reduced by 78%.

Energy efficient building is that consuming the least energy while providing comfort. The energy consumption of buildings, in general, as well as in Serbia, is among other things conditioned by the heating, cooling and lighting requirements with a goal of achieving of thermal and light comfort. Heating energy consumption is the result of heat loss and gain, and their values, in addition to other parameters, depend on town planning parameters. The paper focuses on the comparative analysis of impact of building different exposures to wind as well as on impact of the different prevailing orientations on energy efficiency of buildings.

The potential of energy efficient retrofitting of existing unconditioned buildings to save associated building energy consumption makes it an area of great interest. A questionnaire survey conducted amongst the architecture and civil stream students of Indian institute of Technology (IIT) Roorkee, based upon the questions related to high performance buildings parameters revealed that, energy efficiency is one of the areas which needs greatest attention. The outcome of this survey strengthens the need of such research. Therefore, this research intends to convert an existing unconditioned building to an energy efficient building. For doing so, energy savings opportunities in existing unconditioned buildings are identified and devised into a four – fold energy efficient retrofit model. This paper, evaluates the significance of the proposed four- fold energy efficient model using case studies and energy simulation modeling as a tool.
