Demonstration & Documentation Centre for Sustainable Energy Solutions for Urban Households

A 3-Year Awareness, Demonstration, Monitoring and Result Sharing Project on Urban Household Energy Efficiency funded by Danish International Development Agency (DANIDA)

DDC Project

CETDEM, which always promotes the sustainable use of energy and energy efficiency, launched this project on 1st March, 2004. The aim of this project is to enhance public awareness on this issue by sharing information and demonstrating sustainable energy solutions. The main target group are urban households who have comfortable houses with air-conditioning and hot water supply. This project can educate Malaysians to contribute to sustainable development by promoting renewable energy as a “fifth fuel” and to increase awareness among urban households about sustainable – energy solutions.


A documentation & demonstration centre on sustainable energy usage is to be established in an urban house in Petaling Jaya. The results from the operation of this demonstration centre will be shared/disseminated throughout the country and reinforced with training of urban communities to conduct their own household energy audits.

Efforts will also be made to motivate housing developers and government agencies to make future housing stocks more sustainable in their energy usage. In order to ensure that the lessons are translated into policy, a National Seminar will be held towards the end of the project period to propose a comprehensive National Energy Policy.

Since no such demonstration house exists in the country, it would be a pioneering and modelling effort to have such a demonstration house in Malaysia. Its success would encourage more middle class Malaysians to undertake changes when they next renovate their homes.

In addition, it would provide housing developers of a new approach in building for a growing market of discerning buyers. The Ministry of Housing & Local Government could be motivated to draft an action plan to promote such housing in the 9th Malaysia Plan.

The multiplier effect is certainly possible but by also raising the concerns about modifying lifestyles, the project would contribute towards sustainable development and in the process help the evolution of a comprehensive energy policy.

As local funding for such a project is still not forthcoming. DANIDA support is needed in order to advance existing Danced support in the energy, climate change & NGO sectors in Malaysia.

The Danish partner for this project is The Danish Organisation for Renewable Energy (OVE) that was founded in 1975. OVE is a non-profit, non-governmental organisation (NGO) working for an energy policy based 100% on the use of renewable and sustainable energy.


The objectives of DDC are to:

a. Promote Sustainable & Energy Efficient Lifestyle;
b. Promote Household Energy Audit;
c. Propose a comprehensive National Energy Policy.

Demonstration Cool House

A double-storey house was selected to undergo renovation / retrofitting to become Energy Efficient.

Before Renovation / Retrofitting

As part of the demonstration effort of the project, we have renovated a house in SS2, Petaling Jaya, Selangor to achieve a comfortable temperature the sustainable way. The demo house also utilises the sun to generate electricity and produce hot water.

Although this house does not have air-conditioning, it is quite cool indoor even on a hot sunny day. After renovation works, we have been consistently getting indoor temperatures around 28-30 °C during the day.

What’s more, we are making available publicly the renovation work, its cost and other measures taken to achieve this comfort.

Renovation efforts

The home gains heat mainly from the roof and secondly through the windows. Therefore, the first step we have taken is to insulate the roof with rockwool and provide a “breathing space” between the insulation layer and the roof tiles. The attic space is also kept cool by ventilation.

After – Features of the Cool Demonstration House

Then we shaded the windows from direct sunlight with aluminum sunshades and lots of plants. Plants are really good at providing shade. They look pretty, create oxygen, cool down the air and may attract a wandering squirrel. What more can you ask for?

Besides shading the windows, we also actively manage ventilation of the demo house. Let us first of all visually split the house into 2 sections – the first floor and the ground floor.

The first floor windows are opened in the evening and left open during the night to bring in the cool night air. Throughout the day, the windows are kept closed to avoid the hot afternoon air from entering the house. Heat from cooking is taken out by an exhaust fan. Because no one resides in the ground floor during the night, for security reasons, the windows are opened only early in the morning and closed by late morning. But an exhaust fan at the back of the house is turned on from 9pm until 8am to draw cool air into the house through air vents in the front of the house.

A photovoltaic (PV) panel and solar hot water system is installed on the roof to utilise the power of the sun. The PV panel generates electricity that is sold to the grid. At the end of the month, the electricity bill will show a net of electricity used and sold.



Energy Efficiency Exhibitions to be held around the country to promote Energy Efficiency to the general public.

Energy Efficiency Briefing around Malaysia

Energy Efficiency briefings are arranged and conducted for building professionals, government agencies and school children either at their premises or in a hotel. An Energy Audit exercise is included in the briefing.

Stakeholders Workshop

Stakeholders workshops to be held with professional bodies such as IEM and REHDA. Opportunity to discuss draft Energy Policy Paper and to exhibit project materials including DDC House and Energy Audit exercise.

House Briefing in SS2 Petaling Jaya

You are welcome to come visit and view our demonstration house. House visits are arranged upon request only and usually conducted on a Saturday morning. 1 week’s notice is required. We also conduct briefings to interested houseowners, building professionals, government agencies and school children. Recommended group size is 5-10 persons. Minimum group size is 5, maximum size is 20 persons.
