The design consists of 31 apartment blocks, each six stories tall. The blocks are stacked in an interlocking brick pattern, with voids between the blocks.

Each stack of blocks is rotated around a set of vertical axes, thereby creating a complex interlocking configuration. The axes of rotation coincide with the location of the vertical cores of the building, thereby allowing for a single vertical core to connect blocks at different levels.

Feedback

New configurations of these 31 blocks were sought that optimse certain performance measures. For the new configurations, the size and number of blocks will remain the same, but the way that they are stacked and rotated would differ.

In this procedure, the placement of each of the 31 blocks is defined as a decision point. The process places one block at a time, starting with the first block on the empty site. At each decision point, a set of rules is used to generate, filter, and select possible positions for the next block. The selected option for that decision point is shown as a thick red line.

point block housing An Evolutionary Design Approach

“an automated procedure to evolve design variants that are high in value and performance” 07 | Portfolio of Works

It is envisaged that a developer plans to build a set of residential point block buildings. Flats are always arranged around the core in pairs, sharing a common wall and forming vertical stacks of flats of variable height. At the ground level, each block type can accommodate a different number of flats around the core. The point block configurations are generated using a combination of simple parametric modelling and decision chain encoding techniques. Dynamics particle solver technique is used in order to handle the geometric constraints related to point block positioning.

Clementi Site

FAR: 2.0 6-12 floors 30 Blocks (max.)

Variable Stack Height • Level 1+: Residential units • Level 1: Landscaped deck • Level 0: Car parking

The aim is to optimise the configuration of point blocks so as to maximise saleable value and at the same time maximise window performance criteria.

“a high performance building, not only today, but also after 30 years with a projected 2 deg. Celsius rise in air temperature.”

13 | Portfolio of Works

Form follows Performance The project explores the idea of collaborative work space as a means to a sustainable work culture. A novel concept of form follows performance propels the design process. The urban farm is introduced as a primary strategy to combat various socioeconomic and environmental issues related to climate change. The vertical farm seeks to reduce solar heat gain and ETTV values and also acts as an in-house food source. The facade of the building adopts a continuously varying pattern with the changing climatic conditions. This is plausible by varying plant densities of the urban farm along the length of the facade. A BAU office/research building on average consumes 240 KWh/sqm/yr of energy. This project aims at achieving a benchmark target of 150 KWh/sqm/yr.

The design scenario focuses the need for Singapore to become more self-sufficient in terms food production, since it imports over 90% of its food requirement. Hence, as a long term strategy to ensure food resilience for Singapore’s growing population, a prototypical urban farm typology catering to a population of 10,000 people is proposed. The idea would be to have a decentralised network of such urban farms across various parts of Singapore.

State-of-the-art farming methods would allow essential food items such as vegetables and fruits, fish and chicken to be grown vertically and simultaneously within the same building. The urban farmers who grow the food were to live within the same complex as well. Also, in order to produce a part of the energy to power the building, it was decided to grow algae (bio-fuel) on photo-bio-reactor pipes to be fixed to the parts of the façade receiving the most solar radiation. The market, seed storage, waste recycling centre and many other allied spatial systems were also to be located within the complex.

“an exploratory, self-organisation process that simulates the collective interaction between buildings and its environment”

31 | Portfolio of Works

Agent-Environment Behaviour Tests Straight Diagonal

Buildings are represented as agents that interact with and adapt to neighbouring agents and the environment.

Each agent is an individual building with a set of characteristics and rules that govern its behaviour and decision making capability. The behaviour of an agent (building) with its neighbours over a period of time results in the final location and orientation of that building on the site, and also the size of the building. The relationship between each agent and the environment depends upon a set of agent objectives defined by the designer.

Attractors Repellers

The movement of the agent within the site is stochastic, and as a result each time the simulation is run, a unique design solution is produced. All agents move simultaneously around the site seeking a position that satisfies all their objectives. The objectives may include both programmatic relationships and performance criteria. The task is to achieve a holistic balance of all the criteria for the buildings in the development.
