Renewable Showcase: Commercial and Governmental
 
Introductory brief:
Solar heating is in its infancy even though the technical parameters are well understood.
Have you ever asked yourself why active solar heating has never caught on?  

There are many reasons for limited deployment such as perceived costs and perceived low performance. And yet, the biggest reason is; until now, no one has ever put a cohesive automated package together that stores summer heat for use in winter; a solar system that works even at **5C.

With full DSH implementation, savings would be well documented. It will also be possible to integrate or retrofit monitoring devices to these existing locations to confirm savings and carbon footprint reductions.

This document will be explain the features of the DSH solution:

1. The deliverables: The unique features and what makes the DSH system so attractive in environmental performance, capital cost and large reductions in  Operational Expenses (OpEx) energy savings.
2. The Benefits: What areas can most benefit from the system
3. The Technology: Track record, how it works, why, and existing deployments.
4. Backup heat: Expected standard hydronic backup and spot heating.
5. Cost    

1. The DSH system utilizes sustainable, long term, carbon free, renewable energy that otherwise is wasted.
2. It collects excess summer heat and stores it in a low cost, sub-slab heat-core storage system.
3. Return on Investment (ROI) begins to compound quickly as thermal energy costs increases over the life of the building or facility while the energy cost of the DSH system remains consistently low.
4. Councils and CEOs are gearing up to be functionally/corporately green as well as eco-conscious, and welcome a system such as the DSH system, as real ROI is predictable. An organization could use this in their corporate marketing, and instantaneous data could be utilized for direct website display.
5. The same benefits apply for homeowners, corporates and governments.
6. Capital construction cost is reasonable when installed during construction, most components being available off the shelf.
7. The cost to operate is very low, often equal to one or two pumps intermittently running, that can move megawatt hours of energy.

1. A maximized roof design allows all solar thermal collectors to be situated to maximum effect, and in the optimal solar location and out of the reach of most trespassers.
2. System design and the number of solar thermal panels are optimized for the size of the facility and its estimated loading.
3. A pump station with intelligent monitoring and heat distribution.
4. Historical monitoring of the energy usage offset, the energy produced, the carbon offset equivalences, trees saved and more; linkable to an optional active display system and/or the internet.

1. SPACE HEATING ENERGY: Heating and Indoor swimming pools have massive heating energy demands, it is possible to offset much of this energy demand as well as providing internal heating, along with standard backups, as and if required. A *0% offset is realistic.
2. THERMAL ENERGY: As a rough rule of thumb, each square meter of solar panel aperture has the real potential to generate ~0.9kW of power from the sun. To put this into context, and assuming the roof is limited to a Southern exposure (North of the equator) with a nominal *0m x *0m footprint:
   1. On a sunny day in summer this area will potentially generate the equivalent of ~**6kW
   2. At the end of a *0 hour day this would equate to ~ 7,**5 kW (~6kW real)
   3. Or put another way this is the equivalent of 7.9MW/hours per day or ~*7,**0,**0BTU/day!
3. Calgary is the sunniest of Canada's large cities, enjoying an average of >***0 hours of bright sunshine per year. Given the area in 2 above, this would equate to an annualized energy offsetting of >*2GW (**0days x 6,**0kW). The net result is huge OpEx savings, and equally large reductions in GHG emissions. All roof capacities vary in optimal available real estate available.
4. OpEx: For the portions of time when the system runs, only high efficiency pumps consume any appreciable energy. We estimate for the system described in 2 above, the annualized cost to operate these solar pumps to be ~ $*@******************** would provide significant energy thermal injections depending on structural thermal efficiencies and heated area sizes and demand.
5. DESIGN CHANGES: The existing engineering firms and architects are to be used to integrate the system. The only structural departure from standard hydronic practices is the inclusion of the heat core which is essentially a network of oxygen-proof pipes in sand, in the geo-strata below the slab insulation, with perimeter edge HDPS insulation extending down 2m below the edge of the slab to provide thermal containment, something already present in a frost wall with insulation added. The roof must be engineered for the static load of the solar system, which is nominal.

1. Solar energy is absorbed and converted to heat by high tech evacuated tube solar collectors that function well year-round. The vacuum tubes ensure winter isolation for the solar absorbers. Fluid runs in an insulated header to where it is combined with other solar panel outputs into insulated pipes that transport the heat energy to the pump station(s).
2. Sensors connected to a digital controller and pump station, intelligently trigger pumps when solar panels begin to generate heat in excess of existing or demanded heat levels. All solar heat passes through a heat exchanger keeping both internal and external fluids isolated from each other
3. Thermal energy is routed intelligently to heat areas or pools or high temperature hot water storage tanks, or is injected into the heat core storage as required:
   1. Floor Heat: The solar heat is pumped hydronically through the floor to warm it, and it uses the thermal mass of the concrete to absorb vast quantities of heat energy and slowly dissipate it over time to the insulated environment. The existing slab and (Insulated) frost wall design of most commercial buildings are ideal as these are prerequisites to an optimal DSH design.
   2. Air handlers can be incorporated or run in tandem
   3. Pool: Direct and Indirect Heat is injected by way of a heat exchanger
4. Once these items reach their set-point, excess heat is pumped to the heat core storage system. The  heat core has a maximum programmed allowable temperature.
5. Most heating is accomplished by hydronic heating in floors. A portion may be routed through air handlers for area or spot heating. Hot water heating is direct as is any pool heating. Spot, on-demand alternate heating may be deployed in high energy locations such as doorways.
6. When there is no solar heat available, the controller polls sensors in the heat core to ensure stored heat is hotter than the demanded heat and if so heat is pumped from the heat core using the same piping used to inject the heat into the core. If the core temperature is too low, then backup heat is triggered.

1. The DSH system utilizes long term, pollution free, green, renewable energy that otherwise is wasted, and
2. Excess summer heat can be stored in a low cost, underground, thermal  heat core storage.
3. ROI begins to compound quickly as energy cost increases over the life of the building or facility while the energy cost to operate the DSH system remains negligible.
4. CEOs are gearing up to be corporately green (eco-conscious) and will welcome a system like this as real ROI is predictable. They save money and look good at the same time. They can even use this in their marketing
5. Capital cost is reasonable, & easier to install during construction, most components being available off the shelf.
6. The transitional aspects of conversion to renewable energy source is simple, cost effective and provides a leadership role for participants.
