Cohesion & Harmony at a glance.

Ecologically Sustainable Development (ESD) refers to the environmental component of sustainable development. While urban development is an on-going process, for the sake of future generations, present generation should seek to maintain or enhance the health, diversity and productivity of the environment by placing emphasis on the environmental aspect in the valuation of assets and services. Building serves as an interaction between form, materials, occupants, service plant, control systems and climate. Thus, building planning and design is important in ensuring that the interaction of these factors is cohesive and harmonious. Virtually, this can be achieved through the use of simulation software which allows the designers the ability to “materialise” the building based on their specifications. Building simulation involves recognising and analysing the problems and creating a workable model. Running a simulation basis the required fields will generate results for analysis. Through analysing the results, the energy consumption, thermal/visual/acoustic comfort, passive/active solar potential, indoor air quality, environmental impact and much more can then be investigated before the intangible designs take physical form. To achieve energy management and resource conservation requires effective retrofit and innovatory design measures. Both modelling and simulation are techniques that can assist in promoting the effective but frugal use of energy resources in buildings.

Daylight & Glare Analysis

Daylight & Glare Analysis

Daylight Analysis determines the extent of daylight penetration into interior spaces through glass façades. The operational effectiveness of energy efficient equipment such as photo sensors can be enhanced as it ensures proper positioning. Use of artificial lightings can also be kept minimal as it facilitates appropriate distribution through necessity rather than rule-of-thumb.

Glare elimination and overall visual comfort are two key issues that can readily be evaluated using simulation.

Skylights are designed primarily to bring daylight into interior spaces. Through Daylight Analysis, natural daylighting provision into interior spaces can also be determined as sufficient or not for fulfilling functions and purposes.

Energy Modelling

Energy Modelling

Energy Modelling is the process of re-expressing the building design in a manner suitable for simulation. It is most commonly used to assess the energy use of a building and to derive the savings achievable due to proposed design. Properly used, Energy Modelling can help optimize the building design and allow the design team to prioritize investment in the strategies that will have the greatest effect on the building’s energy use.

Solar Radiation Analysis

Solar Radiation Analysis

A building’s solar characteristics can be determined through a number of different graphical and numerical simulations. Through this assessment, an understanding of the impact of the solar path on the building exterior and interior can be established, through which potential impact of solar heat gain or equipment requirements can also be determined. In addition, as the design progresses, such studies serve as helpful information in identifying periods of time when daylight penetration could pose challenges such as glare or reflectivity, in turn informing the direction of further analysis. They will also help in the selection of facade materials that would provide enhanced interior environmental quality while improving energy efficiency.

A study on the impact of annual sun path on the building development through Sunpath Analysis will faciliate decision-making related to building massing and space planning, thereby determining the building’s final optimal form.

Thermal Comfort Analysis

Thermal Comfort Analysis

Thermal Comfort is important both for one’s well-being and for productivity. Thermal Comfort refers to the state where when the air temperature, humidity and air movement are within the specified range often referred to as the “comfort zone”. Where natural air movement is virtually absent and when relative humidity can be kept at about 50%, the ambient temperature becomes the most critical factor for maintaining thermal comfort indoors. However, temperature preferences vary greatly among individuals and there is no one temperature that can satisfy everyone.

A Thermal Comfort analysis affect the occupants in terms of better overall well-being, enhanced concentration and productivity, and lower the running cost associated with space cooling.

Internal & External Airflow Analysis

Internal & External Airflow Analysis

The exact patterns of airflow occurring in and around a building, the distribution of heat, and even contaminants, can be modelled using advanced simulation software. The results generated can be used to assess the impact of system design and spatial layout on indoor air quality and thermal comfort.

Heat distribution and air movement can also be assessed, determining the effect of the air supply location, flow rate and temperature, extract location and other dynamics within spaces. This can be used to fine-tune air distribution systems (both mechanical and passive) and examine specific design issues such as downdraughts, stack effect, condensation risk and smoke movement. Data from CFD analysis can also be feed into bulk airflow modelling to greatly improve the calculation of infiltration and inter-zonal air movement.
