Green Building Council for inclusion in the Green build 2011 Tours Program.


I am pleased to inform you that your Green Revelation proposal has been accepted by the US Green Building Council for inclusion in the Greenbuild 2011 Tours Program.
Your home will be featured with 2 other high performance residential infill homes. The tour description is below:
Building High Performance Infill Retrofit Homes

There are approximately 7,000,000 existing homes in Canada, many of which do not meet today’s building code standards for energy efficiency. As utility rates rise, there is a greater focus on sustainable renovations and remodelling of our existing houses to significantly reduce the country’s GHG emissions. This tour focuses on three designers and builders who have demonstrated their commitment to sustainability by renovating their own homes as a model for others.  Visit two homes that use the Passive House concept and one targeting LEED Silver.  See sustainable features such as grey water and rain water harvesting, a PAUL heat recovery system, and a green roof.
The half-day tour is scheduled for Friday, October 7 and participants will leave the Metro

Reno or go? How costs should factor into your decision


ROMA LUCIW - The Globe and Mail

We recently had dinner with good friends: four adults, three boys and a baby crammed around a dining room that in pre-children days had felt spacious but was now clearly cramped. Over pork chops and couscous, we mulled their housing dilemma.
Our friends bought their stylish but small two-bedroom home seven years ago. With two energetic, growing boys, the house is now too small. They adore their neighbourhood but prices have spiked dramatically and they cannot afford to upgrade to more spacious digs in their area, leaving them with two options. Option one is to sell and buy something bigger in another area. The second is to do a huge renovation, one that entails digging out their basement, adding a third storey and expanding their kitchen, which would then eat into the backyard.
The problem with option one is that housing prices pretty much everywhere have gone through the roof. Just last month, our friends lost out on a place that might have been their dream house – if it had not been located on a bustling main street. Had they bought it, however, they would have tacked an additional $500,000 onto their mortgage.
That experience left them thinking that perhaps the renovation is the way to go. Although it would let them stay in a neighbourhood they love, the price tag for their desired reno is around $300,000, a large amount of debt to take on for a home that will always have a small lot and compact feel to it. And with the housing market leveling off – if not perched on the edge of a drop – they are reluctant to pour money into a house that might not pay off down the road, should they decide to sell.
Reiner Hoyer, a Toronto-based renovation coach, says when you're deciding whether to renovate or move, there's more to consider than meets the eye. People often forget to take into account the transaction costs of buying or selling a house, for example. A combination of legal fees, real estate commissions and land transfer taxes can quickly translate into tends of thousands of dollars.
But homeowners also overlook many important costs when considering a renovation, Mr. Hoyer says. “Generally, you can take whatever number they assume it will cost and double that.”
To avoid walking into a financial disaster, Mr. Hoyer believes in putting all the reno costs on the table and coming up with a worst-case scenario. “Most people do the opposite,” he says. “They forget this and that and try to believe they can do it for half of what the job is going to cost.”
Instead of just going out and getting a quick estimate from a contractor, homeowners seriously contemplating a reno need to do a real cost analysis. “Soft costs,” such as an architect, a structural engineer, various surveys, variances and building permits, can leave people $10,000 to $20,000 in the hole, he says.
“Good planning is very important; it is not an optional thing,” he added, since a set plan will enable your contractor to give you an accurate estimate of what the job will cost.
“If people want to build a third storey, they need to investigate whether structurally their house can support it.”
Moving fees are another large cost that people should factor into the cost of the reno, Mr. Hoyer says. Although some couples decide to live through the dust and dirt, that decision almost always backfires because the job takes longer and in the end costs more.
Make sure to let your insurance company know that you are undertaking a major reno and/or moving out, he says. Although your monthly insurance bill might go up, you will need the coverage.
And when signing the contract, go over the fine details with your contractor and set up a payment schedule that is based on milestones, Mr. Hoyer says. Decide on a time – say five months, along with a grace period of two months – to get the job done, after which your contractor is responsible for paying your cost of living. Lastly, he added, make sure to hold back at least 10 per cent of the final bill for at least 45 days, which will protect you in case your contractor fails to pay his subcontractors.
My husband and I wrestled with the should-we-stay-or-should-we-sell debate when we were expecting our second child. For those of you struggling with that decision, this website has several helpful tools, including a remodeling vs. moving calculator. My husband and I shopped around, saw the inflated housing prices, and quickly realized that we love our street, our neighbours, our yard and our home. We bit the bullet and renovated. As a reno survivor, I can tell you that the experience is not one I want to repeat but we now have a gorgeous home that fits our family and, hopefully, we will never have to move again.

This will only work in a Passive House: Heating with nothing other than fresh air

compact unit ventilation+heating+dhw for passive houses
This is the know "classical" compact unit: all building services are realised in one handy appliance:
  • heating,
  • ventilation and
  • domestic hot water.
Everything is centred on the element of air: air is the medium that transports the heat (on the supply side), air is the heat source of the heat pump (on the exhaust side). Of course, if necessary, the air could be cooled and dehumidified as well, using the same equiment - that might be interesting in hot climates.
Note that only the fresh air required for indoor air quality is used, there is no recirculated air. That is a difference to the systems in wide use e.g. in the US; those use only recirculated air and a far higher air flow rate.

Fireplace, which is the main heating system in a passive house in Friedberg (architect: Blumrich); this automatic oven is also heating domestic hot water; during summer thermal solar collectors top the concept off.



Compact Units available on the market.
Idea #1: Use the fresh air required for indoor air quality also for heating the building
A building occupied by human beings needs fresh air. If the fresh air supply is left to good luck, it should not surprise if indoor air quality (IAQ) worsens.
If on the other hand the heat from the exhaust air is not recovered, there will be significant ventilation heat losses. It is impossible to realise an energy efficient building in this way - especially if the indoor air quality is to be high as well.
Therefore, for energy efficient new construction or refurbishment a mechanical ventilation with heat recovery is really necessary - this at least holds for cold climates (climates, in which one needs a heating system) and in hot climates (climates, in which one needs active summer cooling). For a detailed discussion of this point, have a look at our page on the topic ventilation.
The supply air, which is delivered by the air-to-air heat exchanger, can transport some heat, too. It is not a huge amount, but just 10 W/m² can be delivered to the supply air rooms using the fresh air required for good IAQ (see the calculation on heating capacity of fresh air). That will not be sufficient at all in conventional houses. But in a passive house, the peak heat load requirement is extraordinary low. Indeed, it will be so low that these 10 W/m² available from a fresh air supply will be sufficient (that in fact is the defining condition for a passive house). Thus, some simplified building services systems become possible in passive houses: “Heating with the ventilation system”, without the need for additional ducts or even without the need for a higher duct cross-section dimension. If, in addition, the heater for the supply air is integrated within the ventilation system and the domestic hot water boiler, one ends up with an integrated compact unit:
Heating, ventilation, domestic hot water and cooling (if necessary) can be supplied by just one appliance. Many solutions can be chosen for heat generation:
  • Use of a small heat pump (Compact unit with heat pump, see figure at left hand side)
  • Use of a small condensing burner (natural gas compact unit)
  • Use of a small combustion unit for biomass fuel (e.g. straw-pellets).

Passive House: Comfort through Efficiency



The Passive House is the world’s leading standard in energy efficient construction: Energy saved on heating is 80% compared to conventional standards of new buildings. The energy requirement for heating is lower than 10 to 20 kWh/(m²a) (depending on climate), adding up to a low cost of 10 to 25 € per month. Therefore high energy prices are no longer a threat to Passive House occupants. 


Exceptionally efficient components and a state of the art ventilation system, achieve these huge savings without compromising comfort, but rather increasing it.

The Passive House concept is a comprehensive approach to cost-efficient, high quality, healthy and sustainable construction. The concept is easy to understand:

  1. Contemporary construction is quite airtight, therefore the air replacement from infiltration is not sufficient. Ventilating by opening windows is not a convincing strategy either. Getting a sufficient volume of fresh air is not just a question of comfort, but a requirement for healthy living conditions. Therefore mechanical ventilation is the key technology for all new construction as well as refurbishment of existing buildings. Mechanical ventilation will work in all cold and all hot climates since in an airtight house, the heating and cooling energy required will be significantly less.
  2. Even though mechanical ventilation systems raise initial investment costs, if designed efficiently they will reduce energy costs significantly, eventually paying off the initial cost.Ventilation units suitable for Passive Houses allow for an economic operation.
  3. Now we explain the central "trick" of the Passive House concept: The fresh air needed is entering the room anyhow. If one could use this air to cover the heating load, without increasing the mass flow, without recirculated air, without noise and without drafts - then the ventilation will pay off a second time.
  4. This concept of "fresh air heating" is only possible in a building with superior thermal insulation, just like a Passive House. For experts: This is the defining requirement; the maximum heat load should be lower than 10 W/m² , allowing the fresh air to carry the heat load.
Passive Houses require superior design and components with respect to:
To realise an optimal interaction of all components, an energy balance of the building has to be worked out. And step by step any new design may be improved to meat Passive House standards.
Thousands of Passive House dwellings are already occupied. Examples will be shown in workshops at the Passive House Conference:
  • Design, redesign, create scopes of opportunity: architecture and the Passive House
  • Passive commercial buildings
A tour of the built  House will follow.
