Integrated Design Process (IDP)

The Integrated Design Process (IDP) consists of five stages and aims to bring all stakeholders together to examine project objectives, materials, systems, and assemblies from different perspectives.

5 Stages of Integrated Design Process (IDP):

1. Predesign:

Determine the project's objectives and vision, including:

Client consultation

Photographs

Measurements

Code review

Programming space and use

Compilation of existing drawings (if any)

Existing documentation and surveys

Statement of probable construction cost

Preparation of high-level base drawings

2. Schematic Design:

Create rough sketches that illustrate the concept design in compliance with rules and regulations. By the end of this phase, drawings should include:

Building cross-section

Typical wall section

Floor plans of all levels with general openings and plumbing fixtures

Exterior building elevations with openings and finishes

3. Design Development:

Finalize the design with specifications for materials, window and door locations, and general structural details. By the end of this phase, drawings should include:

4. Construction Drawings:

Prepare final construction blueprints, notes, and technical specifications necessary for bidding, construction, and permit applications. Contractors use these detailed drawings and specifications to prepare for construction.

5. Construction:

Build the project according to the design intent. In case of changes, discussions with the owner about changes and options ensure that alterations are compatible with the owner's vision for the project.

Problem-Based Learning (PBL)

Problem-Based Learning is an approach where students learn by actively solving real-world problems. Instead of lectures, students work on problems or scenarios, encouraging critical thinking, collaboration, and practical application of knowledge.

Benefits of PBL:

Retain more core factual knowledge longer and re-use it

Relate theory to practice

Higher order thinking – critical & creative

More engagement & empowerment

Things I've learned from this week

Non-GFA: Refers to voided areas, such as empty or unused spaces within a building.

Biophilic Design: A concept employed in the building industry to enhance the connection of building occupants with the natural environment. This is achieved through direct nature (like plants), indirect nature (such as natural light), and considerations of space and place conditions.

Green Replacement: The practice of incorporating green elements, such as vegetation and greenery, into the design of buildings.

Piezoelectric: The property of certain materials to generate an electric charge when subjected to mechanical stress or pressure.

Design brief of south zone

Identify areas of improvement in the zone

Refer to GM 2021 to find sub section related to the area of improvement

Propose design ideas for it

The area targeted for the design idea

Classrooms in Temasek Poly are usually facing west

Window design must be considered

Most of the heat from evening sun comes from west side

Stormwater runoff - Excess water from rain that flows over land surfaces rather than infiltrating into the soil

Stormwater management - Controlling the quantity and quality of rainwater runoff that occurs during storms or heavy rainfall

Rain garden - Garden that helps manage stormwater runoff from rooftops, driveways, sidewalks, and other impermeable surfaces

Open grid pavement - Type of pavement surface that is designed to allow water to infiltrate through it and into the underlying ground

Green Plot Ratio - Measurement of the amount of greenery or vegetated space in a particular area or development relative to the total built-up area, calculated by :

Total leaf area of greenery counted as landscape replacement (softscape)/Total site area of development

LAI (Leaf Area Index) - Parameter used to quantify the density of vegetation cover in a particular area

Renewable energy integration (reduce energy cost)

Smart systems (advanced building management systems)

-Sustainable materials (reduce carbon footprint)

-Water efficiency and water usage

What does it take to go from platinum to SLE?

Renewable Energy

Integrating renewable energy sources like solar panels, wind turbines or geothermal heating and cooling systems to reduce building's carbon footprint

Water Efficiency

Go beyond standard water conservation measures with advanced technologies like greywater recycling and rainwater harvesting

Green Materials

Selecting building materials with the lowest environmental impact, such as those with high recycled content or sustainably sourced materials. Consider materials that are both durable and low in toxicity

Difference between a platinum rating and Net Zero building

Platinum BCA Rating (Green Mark Platinum)

- Criteria-Based: BCA's Platinum rating is highest tier in the Green Mark scheme. It evaluates a building's performance across several categories, including energy and water efficiency, indoor environmental impact, sustainable features and practices.

- Holistic Approach: Beyond just energy, the Platinum rating considers a building's entire environmental impact, from the materials used in construction to the building's integration with its surroundings.

- Quantitative Metrics: A building must meet specific numerical thresholds in each category to achieve Platinum rating

Net Zero Building

- Energy Specific: A Net Zero Building specifically refers to energy balance. It produces as much as renewable energy on-site as it consumes on a daily basis. Focus is solely on energy equation

- Varied Approaches: Net Zero can be achieved through combination of energy-efficient design and technologies and on-site renewable energy generation

- Operational Achievement: While design is crucial, achieving net zero status is also about how the building is operated. Energy consumption must consistently be offset by renewable energy pollution
