using the SUN to heat, cool & power your home

Welcome to CRE Green Consulting, where you will find cutting-edge, all-in-one solutions to save on your monthly energy bills and increase your property value.  Our exclusive technology uses the sun as the source for all the energy needs in your residential or commercial building!

At CRE Green Consulting, architect Hill Jiang and engineer Franzi Tschurtschenthaler, will design your sustainable house using cutting edge green energy techniques and technologies, such as Building Integrated PhotoVoltaics (BIPV), net-zero design, solar water heating, solar HVAC systems, and more.  Our team finds solutions for our clients with zero-emissions as well as zero-energy consumption, with the end result being cost savings on utilities and the reduction or elimination of one’s carbon footprint.

Note: Ongoing progress on the CRE demonstration project on a residential home in Kelowna, BC, is constantly updated in our Blog section.

Our BIPV system revolutionizes conventional power generation, with de-icing & snow-melting function for our panels, a heat collection system for HVAC support, and a built-in setup for solar hot water heating.  Instead of attaching photovoltaic solar panels to the roof as an afterthought, our system acts like a large integrated solar shingle.

Our comprehensive BIPV system includes the following major technologies:

• air & water based heat collector (BIPV shingle)
• Solar HVAC system
• solar railings (BIPV railings)
• solar carport (BIPV carport)
• solar driveway & walkway (Road Integrated PhotoVoltaics, RIPV)
• 3 in 1 solar water heating solution
• off-grid battery bank with Electric Vehicle (EV) charging system

We have a full demonstration of the above principles at our local ‘Living Lab’, which is monitored through joint partnerships with the University of British Columbia Okanagan.  We welcome visitors, and more information can be found on the Contact page.

This is the R&D information and educational branch of the website Createsolar.ca , a premiere solar energy design & construction firm in the Okanagan.  We are the local forerunner of smart, all-in-one home energy solutions, which include the aforementioned solar HVAC, BIPV, solar hot water, solar driveways, solar canopies, solar railings, solar heated pools and further unique solar technologies.

If you are a home owner, home builder, or property developer, then you have come to the right place to save on energy costs and increase your profit margins.  If this is your first time here, we highly recommend that you check out the all-in-one technology description of our solution.  The best part of it all, is that while you are saving money you are also contributing to saving the planet.

Technology Definitions

Solar HVAC is short for Solar Heating, Ventilation and Air Conditioning, which aims to improve on a traditional HVAC system.  Instead of using gas or electricity to heat your house in winter, we turn the suns radiation energy directly into HEAT with a whopping efficiency as high as 50%.  For summer, we collect and store the cooler air after sunset, which is then used to cool down the house during the day.

Net-Zero is a term to used describe when an energy efficient building’s energy production is equal to its consumption.  Normally when people hear about a net-zero house, they tend to think that this type of house can only be built with a much higher cost and tighter insulation.  This has typically been true in the past when designing with the German Passive House concept and using exclusively photovoltaic solar panels.  However, with CRE Green’s design of heat collecting panels, and smart air and electronic controls into the overall home system, net-zero becomes much more cost effective and easier to achieve.

BIPV stands for Building Integrated PhotoVoltaics, which is a way to describe when solar is incorporated into the overall aesthetic and design of a building and not simply as an addition, as has been the traditional way of looking at it.

The diagram you see above is the general layout which shows the core of how everything concerning the solar heating works. You can click here to see a better and larger diagram. The following slideshow demonstrates each step of the principle behind the whole system.

Houses built from the foundation up using our system, feature a south-facing roof which is hollow, allowing air to flow inside.  As the roof’s exterior warms from sunlight exposure, fresh air is drawn inside from vents within the BIPV panels and the heat collecting panels.  As the panel surface heats in the sun, so does the air inside the cavity which rises to the ridge. The hot air then passes through a fan-driven handling unit, forcing it downward through a large vertical duct. The ground floor is typically elevated above the foundation to form a plenum. The hot air enters the interior through floor vents placed throughout the house.  This concept is shown in the following schematic:

During night time while there is no sun, the heat in concrete and the exchange space gets slowly released, thus not allowing the room temperature to drop drastically.  In the north of certain provinces which are very cold, an additional heating source is built in as a backup, which can be seen in the two diagrams below:

It should be noted that the whole process gets controlled smartly through the use of software and hardware sensors, so that everything works in unison.

There is also the issue of cooling the house during the summer.  This is described by the following two schematics, which show that we’ve got both the summer daytime and nighttime scenarios covered:

Beside solar heating/cooling, we can also install BIPV solar panels on your roof and a solar hot water tank in your basement to further complement the system. The former allows you produce enough electricity to sell to the grid in summer times, while the latter provides the household’s necessary hot water through the excess heat produced by the panels.

In addition, it is typical for clients to ask about the storage of solar energy through the use of batteries.  This is a possibility, however it is currently not financially wise to setup the system in such a way.  Instead, it is more cost-effective to hook up all of the electricity generating unit to the grid through a NET meter.  This way, you can sell any excess power you are not using during the day back to the grid at the same rate you are buying it for.  This is a much more efficient way to recover the costs associated with installing the panels.  It also allows you to buy your electricity from the grid at night, or whenever there is not enough sunlight to meet your needs.

The image below shows the rooftop portion of our installations with both the Solar HVAC (Heating, Ventilation and Air Conditioning) collector panels and the Building Integrated Photovoltaics (BIPV) panels visible. (The solar hot water tank, handling unit, control display and other parts of the system are inside the house.)

More images taken from our installations, and also from OMSolar.jp and AlaTown.com, can be found here. If you prefer watching videos, they can be found here.

You may ask if one can you incorporate this new system into an existing house?  As a matter of fact yes!  We are currently retrofitting an old house in Kelowna, BC.  The address is 727 Cassiar Crescent, which is also the location of CRE Consulting’s ‘Living Lab’.  Please click here for more information on this conversion.
