Green Sustainable Free Heat ~ Significantly lowers OpEx & related Greenhouse Gas Emissions.

GHG/Carbon emission savings are significant

Heating and hot water heating are one of the greatest sources of significant GHG carbon emissions: Carbon dioxide (CO2) emissions from carbon fuel combustion, represent the majority of greenhouse gas (GHG) emissions in Canada and around the world.  CO2 from fossil fuel combustion represented approximately 75% of Canada's GHG emissions in 2011. Roughly half of these emissions  can be attributed to residential and commercial or governmental space heating.

The DSH system can be scaled up to suit almost any area as long as the corresponding area is suitable for adding storage and solar panels with reasonable solar access. As a rule an ideal candidate would be a large area building on a near grade slab. Shopping Malls, Warehousing for example or Sports complexes, especially those with Swimming Pools, can greatly benefit in both OpEx and GHG emissions reduction.

For every unit of heat energy offset, an equal related amount of GHG Carbon emissions is also typically offset. In areas where heat energy or electrically generated heat energy is typically generated by less clean fuels such as Oil or coal, the reduction in GHG emissions is potentially huge.

Commercial payback can be quite reasonable, and given the possibility of government subsidies, the number drops even more.

OpEx savings are significant

If you had the power to reduce the GHG AND the heating OpEx costs by 50% or more, for a new building, would you?

New Commercial properties can benefit hugely from integrating the DSH technology into the  new heating system in a new facility. Benefits include but are not limited to: OpEx reductions and 100% Carbon emissions offset reduction. Some existing properties can also be retrofitted, especially those with existing Hydronic Heating

Give the relatively simple understanding that MW of energy are available for injection into most building projects, it makes good financial, Eco-friendly and common sense to use this sustainable resource to lower emissions and reduce operating costs (OpEx). It is almost criminal not to, given our joint responsibility to the state of our planet. If you can save budgetary OpEx funds at the same time, then this is a win-win situation.

Added Design Requirements:

If a property has a slab foundation or floors, has reasonable solar access, then it can be considered a prime candidate for the DSH system. More floors can be considered on a case by case basis.  Deep U/G parking can be nominally problematic and are quoted on a on a case by case basis.

The low cost heat core storage system uses a specially designed and insulated sub surface geo-strata to provide massive, low cost thermal mass storage.

Added typical design requirements are nominal:

  • Perimeter insulation, depth ~2M, sealed to sub-slab HDPS insulation, with ext vapour barrier
  • 140mm sand layer under sub-slab HDPS, O2 proof PEX installed in the lower 50mm.
  • Energy Efficient design,  with Hydronic heating: of slabs.  Backup can still be any (demand) boiler or Heat Pumps
  • Piers or similar are a non-issue
  • Roof design allocation and rated for solar panel array, typically flat roof.
  • Conduit for sensor wires and hydronic pipes from roof to pump station.
  • Mostly Std Hydronic heating in-slab.
  • A thermal heat core storage area under the slab needs to be added to the foundation design. This heat core has an insulated perimeter to a depth of ~2M under the edge of the slab and under-slab.

Roofs are not the only location worthy of consideration if roof real estate  is limited or not easily available.

The heat core must be low cost and massive to store the huge influx of thermal energy in summer while allowing deployment of enough solar panels to directly heat  in winter when the sun is active.

Examples of the types of buildings that can significantly benefit form the DSH System:

  • Community centers and council or government buildings. pool
  • Recreational centers, especially those with swimming pools
  • Warehousing: an ideal DSH solution.
  • Offices, commercial buildings
  • Retail boxes and shopping malls
  • Schools and retirement centers
  • Airports and aircraft hangars
  • Gymnasiums and drill halls
  • Hospitals & Hotel/Motels & laundry

 

Most of these building are slab-near-grade or slab on basement, with perimeter insulated sub-walls or frost walls, This is ideal and only nominal engineering requires updating. Piers or piles present no significant issue.

In addition, manufacturing can utilize the DSH system for process heating and pre-heating. Businesses that require heat can include Car Wash's, Laundry, and process heating.

Deliverables:

  • Imagine: Free Heat that can offset much or all of your heating and hot water energy expenses, every year.
  • Imagine: Reducing carbon based heating & hot water costs by 50 to 100%, depending upon location, and design.
  • Imagine: Reducing your Greenhouse Gas & emissions footprint, possibly generating future carbon credits.
  • Imagine: Quiet, comfy, dust free operation for Heating and Hot water.
  • Imagine: Locking down the ever escalating heating & hot Water energy costs

Current Expectations for Calgary target  offsetting close to 65-75% of heating and hot water over a year.

Costs:

Costs vary somewhat depending on location, type, roof space and orientation. It also varies with loading, for instance the inclusion of s Swimming Pool can greatly affect the solar Panel requirements. Thus there is no rule of thumb for pricing.  In reality the DSH system is often seen by governing bodies as the offset backup heating system.

Some legislative bodies also provide grants or other encouragement to reduce Carbon Emissions.

Backup:

Backup heating infusion is required by code, and this is designed to manage all heating & H/W needs at highest demand times.  Backup can take the form of high efficiency demand heating, or boiler or in some locations a heat pump.

The net result for many customers will be: reduced or no furnace or ducting, Dust free and super quiet operation,  Much lower annual  energy costs, a huge reduction in GHG (Greenhouse Gases),  not to mention pride of ownership where solar panels are a statement. We consider the DSH system to be primary, however to be clear, the backup is primary in the eyes of regulators.

Timeline and History:

The DSH system was developed over the last 10 years with many systems successfully operational in the colder winter areas of NZ and Australia. From 2013 to 2015,  the DSH system is being redesigned for the harsh North American winters and soon qualification confirmation testing will begin in the Calgary Area. Once deliverables are confirmed, the system will go into full production with an eye towards the rest of Canada and the USA. The DSH N. American version of the system is expected to go live in 2016, with some BETA test sites operational in 2015. (Interested in becoming a Beta Test site?). The N. American version has involved significant changes, to work in the colder North American climes.

Time Sensitive? The critical O2PEX installation in the foundation can be pre-installed during foundation construction. It can be problematic in many instances to install the heat core and slab pipes retroactively. Sites with preexisting hydronic heating can be assessed individually for retrofit acceptability.

Currently deployment expectations:

    2015: Develop beta-test sites & fine-tune engineering. Interested parties please inquire.

    2016: Begin deployment of DSH

    2017: Add more international sites

    2018: Finalize development of Solar powered Air Conditioning & Waste heat optimization.

The DSH system:

What sets the DSH system apart from any other solar augmented heating system is the patented, low cost, massive, solar heat core storage system that stores summer heat for use in winter. This was a game-changer; now enough solar panels can be installed to make a substantial difference in winter. Allowing enough engineered solar panels to be installed to make a real difference in winter was also a key ingredient. Normally, extra panels would create huge issues in summer if we were unable to store the enormous thermal energy generated. The DSH system also uses high tech, Vacuum tube solar collectors that would provide heat even at -30c on any sunny day.

Training:

DSH will provide training in both design, installation and commissioning. Individual training will be provided for Beta or Test sites, eventually combined training sessions will be held for design and detailed training manual provided in soft form.

DSH is looking to work with a few Architects, designers, developers, and builders, to install a limited number of beta-test locations, in both homes and commercial properties, especially warehouses. Other key commercial properties are: hotels motels, laundry, car washes, retail spaces, schools, and sports complexes, especially those with pools.
