Façade Thermal and Condensation Risk Analysis

ALT performs thermal performance simulations of the façade components. This is essential to ensure the performance complies with local and international codes. Parameters such as U-factor and SHGC are calculated as inputs to energy models or HVAC equipment sizing.

In cold areas, condensate formation along the interior face of the façade components is susceptible to happen. Through condensation risk analysis, ALT checks the condensation prone areas and provides design changes to lessen or eliminate its occurrence.

Solar Access Analysis

Solar access basically refers to the availability of incident solar radiation (insolation) on a surface e.g., the exterior of a building. Say you intend to check feasibility of placing solar heat collectors on your building roofs or you simply want to analyze insolation along different building orientation for a specific season, then ALT can perform the analysis for you. Through this study, you may get an idea on the average, maximum, or even the cumulative amount of insolation on a specific surface given a time period. Overshadowing of nearby structures can also be accounted.

Daylighting Analysis

Daylighting is the practice of using natural light to illuminate building interior spaces. Through Daylight Analysis, ALT may check the amount of daylight being admitted inside building rooms and check if it satisfies the requirements of daylighting credits of rating systems such as LEED, BREEAM or Green Star. A thermal map will also help you visualize the daylight distribution at a specified working plane height.

Comparative Building Energy Model Study

In cases of multiple façade options, ALT can perform building energy modeling to give you an idea on the façade energy performance. Modeling parameters are held constant as varying façade options are evaluated. Energy savings from the different options are then calculated in comparison to a reference baseline model.

CFD Analysis

ALT can perform internal and external Computational Fluid Dynamics (CFD) analyses to check air pressure, velocity and temperature (internal) distribution inside the building areas or along the building perimeter. At a selected slice selection frame, contour bands and vectors can be plotted to visualize the selected parameter variation or flow.

As the most widely used third-party green building rating system, LEED® or Leadership in Energy and Environmental Design incorporates sustainability and integrated design at every phase of a building project. Based on the number of points achieved, a project may obtain one of the following LEED® rating levels: Certified, Silver, Gold or Platinum.

Through LEED®, a building project is geared towards having energy and water efficient design, environment-friendly construction and a healthy indoor environment. LEED® certified projects get a big boost to its public image, have faster lease-up rates and may qualify for incentives like tax rebates and zoning allowances. These green buildings also retain higher property values.

As an organization that supports sustainable design, ALT will help you realize your project sustainability goals through its LEED® Consultancy service program. Housing a number of LEED® Accredited Professionals and Green Associates, ALT can guide your team through the LEED® certification process.

Design Phase

We shall conduct a LEED® Charette to ensure integrated design and establish goals, credits to be pursued and confirm target certification. We will set-up the LEED® Project team and assign tasks to each member for the design documentation. Energy modeling runs shall be performed to simulate building performance and obtain energy savings against a baseline model. We shall then submit design phase credit documentations to LEED® Online for review and coordinate with the design team to respond on comments and technical advice from the reviewers.

Construction Phase

We shall set-up the LEED® Construction team to implement best practices for sustainable construction. We shall assign tasks to the construction team on credits for construction documentation. We shall review monthly reports and progress of LEED® credit implementation and monitor compliance on-site. We shall submit construction phase credit documentations to LEED® Online for review and coordinate with the construction team to respond to comments and technical advice from the reviewers.
