CapitaGreen is a 82,000 sq.m., 43-floor skyscraper in the Central Business District of Singapore1. The Video looks at its design for Sustainable Ventilation.
45 m1 tall Wind-Catchers atop the skyscraper are oriented towards the prevailing wind direction2. Designed to scoop winds at this elevation, they channel air down a core known as the ‘Cool Void’3. Air from the cool void spreads horizontally through the levels, reducing Air-Conditioning loads.

While researching various Passive Strategies and Technologies for the Building Envelope, we came across ‘Cool Roofs‘. We realized that this is a simple, low cost technology with large potential benefits. These include – Energy savings, Reduction of Urban Heat Island Effect and Greenhouse Gas Emissions, enhanced Durability of roofs, and Resilience to extreme heat 1.
Thus, this week’s Article and Video are dedicated to this important idea. The Video 2 , 3 , 4 outlines the Need for Cool Roofs and how they Protect Buildings. In the Article, we cover Initiatives by various parties working in the direction. We also look at some successful Case-Studies that could become models for future developments.
Due to multiple possible benefits, the technology has caught the attention of International actors, Indian central, state and local governments, as well as the Private sector. Their attempt is to use Cool Roofs for large scale Impact at the Building and Urban scales.
The above efforts are helping common people as well as experts to understand and utilize Cool Roofs, by providing technical information, tools and answers to common questions. The following examples showcase successes in the field.
We leave you with the following questions –
Let us know! We would love to provide a platform, to showcase your project and spread more useful information.

These faces of the building are difficult to shade, as they receive low angle rays from the rising and setting sun. Common shading features such as horizontal projections, usually fail in such situations. Our 3 case-studies explain methods to address these tricky areas of the building.

This post is an Introduction, that leads to a chain of articles in the coming weeks, focusing on Energy @ the Building Scale. We felt this important scale merited further mention [an extension of ‘Part 4/5: The Red System (Energy), Singapore’ – Published: 28th May 2018]. These articles are also part of our effort to explore and possibly prove that ‘Passive strategies’ for Architecture are still vital for Energy efficiency and Sustainability in today’s world.
DPR’s Phoenix office cleverly combines passive strategies like Natural Ventilation and daylighting, with Active smart controls to create a Net Zero certified building that also acts as a Living Laboratory. Having achieved this in the harsh hot dry climate of the Sonoran desert, sprouts hope for Passive design.
This is part of a series of posts based on scripts, written for class presentations during our Masters in Integrated Sustainable Design at National University of Singapore.
The class had to analyse various complex systems in Singapore, as a precursor to the Design problem in Studio. The systems included are – Red (energy), Blue (Water), Green I (Biodiversity), Green II (Food) and Grey (Public Space).
The following posts elaborate on the Red System.
Welcome to Part 4/5 of our series on the Energy System of Singapore. Part 1/5 established that the system has a gap at the neighborhood scale, that it is highly centralized and the largest demand sectors are Industrial and Commercial. Part 2/5 analysed the timeline of the system from the 1800s to present day, and looked on to the future – with a focus on important policies and events, and their corresponding effects.
Part 3/5 looked more deeply into the System’s Flows & Exchanges. Important findings were that there is a high dependence on fossil fuels mainly Petroleum Products and Natural Gas for both direct consumption and generation of electricity. Also, despite efficient gas turbines for electricity generation, there are high conversion losses of up to 40 per cent as heat. However, the transmission losses remain low. A large percentage of transportation is also powered using fossil fuels. Within sectors, the highest consumption is for air-conditioning loads. Considerable waste heat is generated from processes, adding to environmental heat and affecting micro-climate.
Moving on from this understanding, in this post we explore the System Structure in greater detail on 3 scales – Island, 10 km X 10 km and Building.

The following posts elaborate on the Red System.
Welcome to Part 3/5 of our series on the Energy System of Singapore. Part 1/5 established the objective and boundary condition of the system. It then identified the Elements, and Flows & Exchanges between them, to set relevant scales of study and understand critical functions. We found that the system has a gap at the neighborhood scale, it is highly centralized and the largest demand sectors are Industrial and Commercial. Part 2/5 went deeper into the analysis by looking at the timeline of the system from the 1800s to present day, and looking to the future. The timeline reflected important policies and events, and their corresponding effects using maps at Regional and Island scales.
Moving on from the above base, this post delves deeper into the System Flows and Exchanges. The Analysis is divided into 3 sections – Generation, Transmission, Distribution & Consumption.

The following posts elaborate on the Red System.
Welcome to part 2/5 of our ongoing series, on the Energy system of Singapore. The last post established the objective of the system. We then started analysis by first establishing a boundary condition and later identifying the system’s Elements, and the Flows & Exchanges between them. This was done to set relevant scales of study and understand critical functions such as generation, transmission, consumption. We gathered that there is a global scale and 3 local scales for this system – Island, 10 km X 10 km and building. There is a gap at the neighborhood scale. We also found out that the system is highly centralized with high demand from various sectors, the largest being Industrial and Commercial.
Keeping this base work in mind, we move deeper into the analysis and understand the timeline of the system starting all the way from the 1800s to present day. We also look at future aims and targets to address present issues.
