Dear Mr. Tung:

On behalf of the Right Honourable Stephen Harper, I would like to thank you for your e-mail, in which you raised an issue which falls within the portfolio of the Honourable Gary Lunn, Minister of Natural Resources. The Prime Minister always appreciates receiving mail on subjects of importance to Canadians.

Please be assured that the statements you made have been carefully reviewed. I have taken the liberty of forwarding your e-mail to Minister Lunn, so that he too may be made aware of your comments. I am certain that the Minister will give your views every consideration. For more information on the Government's initiatives, you may wish to visit the Prime Minister's Web site, at

Energy efficient city farming proposal

Hi-Tech Group has been researching future farming methods to propose to the Government of Canada. We request that our government would consider to co-operating with us to build an experimental farm for setting guidelines of future city development. The guideline will eventually be an environmental protection law that will exceed the requirement of Kyoto Accord.

To covert heat loss to be a gain:

The physics of hot air always rise is a proven phenomenon. Scientists understand very well that our roof is the biggest enemy to energy conservation. However, they are only trying to prevent this enemy doing less harm. They did not consider utilizing this enemy to work for us. We can convert this enemy to be our friend; a very useful friend, which can solve many problems, such as energy, emission, environment, food, employment, economy, financial and etc.

I have only few hundred square feet of a vegetable garden. However, I discovered that this small piece of land could produce far more than enough food for my family to consume during summer. Unfortunately, summer is very short in Canada. I wish I could use a green house to extend my growing seasons. The energy consumed by the greenhouse will be far more expensive than the food produced. In addition to the impact of emission damages to the environment caused by heating the green house.

I realized heat lost through rooftop during winter is un-avoidable no matter how thick the insulation you have installed, then, why don't we build green house on rooftop to obtain free heating. We can double spend our energy before releasing them to the atmosphere. An extra floor could make our house have better insulation too. That would save energy.

During very hot summer day, I observed that my office could not cool down no matter how low I turned my air conditioner. At home, my top floor is always warmer then the lower floor. Sunshine on the roof will conduct heat to my living quarter; making it very un-comfortable to live in. Everybody crank up the air conditioner to maximum even hydro companies warn people that they could cause a black out if they do not restrict themselves. I thought why we don't use the roof as green house to absorb the abominable heat. I could save energy bill again.

Living in cavern has year round comfortable temperature. We can emulate cavern living by using technology in nowadays.

There are too many nice farmland consumed by industries. Multi acre warehouses and office buildings are getting very common. We can use technology to recover lost of farmlands.

How the government should response:

I could not think of any natural reason which could cause our experimental farm fail. The theory is well proven. The experimental farm is practically just a demonstration. We would use it for scientists to collect data for estimating how successful we could to exceed the standard of Kyoto accord. I estimate we could reduce the emission by at least 50%. We just need some numbers to convince our politicians. Government could use
incentive method to encourage citizen to participate. Therefore, our government does not even have to spend any money to set up the system. Contrarily, tax income would be increased because of employment created and booming of new industry. It will also make us less reliable on import of fresh vegetables. If our government implement this system first, we could gain the reputation of pioneer on environment protection, and set as an example to the world.

Methods to implement:

bulletMake laws that all new buildings must make rooftop green.
bulletEncourage old building landlords to participate by re-appraise the property tax under farming industry status.
bulletSubsidize or give low interest loans to house owner to do conversion. Especially when they are re-roofing.
bulletLarge area rooftop will have better priority to consider.
bulletEncourage architects to make good appearance and environmental designs.
bulletEducate green house farming.

Advantage of promoting the building of green house on rooftop.

bulletIndoor is cool in summer, reduce electricity bill, lower emission in hydro plant.
bulletIndoor is warmer in winter, reduce heating bill, lower emission on fossil fuel.
bulletRecover the lost of farmland used by industry.
bulletCan produce food year round.
bulletEasier to control plant disease and insects.
bulletLess insecticide used. More organic. Healthier food.
bulletRooftop has better sunshine than ground.
bulletConsider enclosed rain collector for irrigation, and solar water heating panel in the design.
bulletCan collect rent. Extra income for landlord.
bulletCan reduce imports. Retain money currency value.
bulletEliminate logistics of produce. Consume locally. Reduce emission on trucking industry.
bulletCan create many small businesses. Farmers in cities.
bulletCould boom the following type of business. Glass, plastics, aluminum, lumber, seed, soil, honey, gardening supply, building, and etc.
bulletCould create many employments. Such as growers, salesman, construction workers, drafting personnel, etc.
bulletGlass rooftops will last much longer than shingle rooftops. No re-roofing is required. Shingle roof has a life expectancy of 20 years, can create lots of building material waste. Extra cost on doing conversion could be recovering in very short time by collecting rent and reduced maintenance cost.

Please find enclosed Ministerís Strahlís reply to your correspondence

Dear Mr. Tung:
        I am writing in response to your email to the Right Honourable Stephen Harper regarding your proposal to build an experimental farm that would test the idea of constructing greenhouses on the rooftops of buildings to conserve energy
normally lost while heating buildings. As you know, the Prime Ministerís Office forwarded a copy of your email to the Honourable Gary Lunn, who in turn had a copy forwarded to the Honourable Chuck Strahl for consideration. The Minister appreciates being made aware of your suggestions and has asked me to provide you with the following information.

        Agriculture and Agri-Food Canada (AAFC) scientists conduct mostly agronomic practices and pest and disease protection research for the Canadian greenhouse industry. Energy use in the greenhouse industry is always a concern, and many greenhouses are considering using heating alternatives such as waste wood, pelleted biomass, crop residues, and plantation biomass such as willow. AAFCís direct mandate, however, relates more to plant production and agronomics.

        Natural Resources Canadaís Office of Energy Research and Development (OERD) has several energy-related programs that may be relevant to your interest in conserving energy in buildings. Information on a variety of OERD programs that may be useful to you is available online at Of specific interest and assistance to you may be the Buildings Energy Technology Program, which can be found online at

Mr. Michael Tung

Alternatively, you may wish to write to the OERD office at:

        I trust this information is of assistance to you, and I wish you every success with your proposal. Thank you for writing on this matter
