An earth energy system is part of a heating, ventilation and air conditioning system HVAC for a building or structure.

CAN/CSA C448 Series-13

Table 1 does not cover all system scenarios such as shallow horizontal excavation open loop systems. For the design of a surface water or submerged closed loop system, the standards Section 6. When required, groundwater is pumped out and heat is extracted. Underground thermal energy storage systems formerly, contained within previous editions of this Standard under CSA C The two standards do not provide information on the type of grouting mixtures to use nor discuss when various types of bentonite or cement are to be placed into the hole.

Already Subscribed to this document.

We have no amendments or corrections for this standard. Heat is then transferred to the outside loop and is released into the ground or surface water. The diagram uses a red colour on the left side of the horizontal U loops and the other horizontal tube in the ground to the heat pump in the residence.

The schematic traces the movement of heat cda follows:. Figure 3 is a drawing showing an example of an open loop surface water geothermal system. An example of not meeting the purpose of the Act could be the taking interferes with another person’s well.

The vertical loops are connected at the central csq and form part of a continuous loop which extends from the ground into the home and back. The water discharges into the river. You may delete a document from your Alert Profile at any time. The lack c448 a sealant between the pipe and side of the hole, however, increases the risk of the hole acting as a pathway for contaminants.

More information on Permits to Take Water can be found at: To protect, conserve and manage water resources, the Ministry of the Environment administers and enforces a permit program for the taking of water. To store heat cza a BTES system, a continuous sealed loop of tubes, through which a heat transfer fluid passes and returns, are placed into holes in a similar fashion to a closed loop system. If the document is revised or amended, you will be notified by email.

If a designer chooses not to follow the prescriptive requirements of the Building Code Regulationthen the designer must propose an alternative design which meets the objectives and functional statements as stated in the Supplementary Standard SA-1 of the Building Code Regulation When proposing an alternate design for an earth energy system, Supplementary Standard SA-1 requires a designer to meet objectives OH1.

The schematic traces the movement of heat as follows: In a vertical DX system, the tubing is installed into vertical, including directional or angled, holes and backfilled with a bentonite, cement or sand product. The values given in the parentheses are for information only.

A DX system is a type of closed looped system that eliminates the need for an antifreeze mixture heat transfer fluid.

This consolidated version of the C Series x448 was reprinted in October to incorporate the update 2 dated October into the original cs. Contact information for Department of Fisheries and Oceans Regional Offices can be found at the website. The heat transfer fluid is circulated within tubing, absorbing heat from the surrounding rock, soil and groundwater and storing it for use at a later time.

Mineralized water, gas and oil can migrate along open holes cwa with an earth energy system and impair other fresh groundwater zones. CSA Group is embarking on this bi national development in an effort to best use diminishing volunteer committee member time and we are inviting you to be a part of this project.

A Permit To Take Water is generally not required for the operation of a closed loop, DX or BTES earth energy system used to heat or cool an industrial commercial building because, although tubing is installed into the hole or surface water body, no water is being taken. Please first verify 4c48 email before subscribing to alerts. The well is constructed with a steel casing that extends from above the ground surface through the overburden into the top bedrock and is constructed as an open hole typically The annular space between the steel casing and borehole is sealed to prevent flow from ground surface into the csx.

Notes to tables and figures are considered part of the table or figure and may be written as requirements. There are two common types of thermal energy storage systems in Ontario: The water table is csq just below the bedrock surface. CSA Standards CSA Standards is a leading standards-based neutral not for profit organization serving industry, government, consumers and other interested parties in North America and the global marketplace.

The bottom of the sleeve contains perforations to allow the submersible pump to extract groundwater from the formation through the waterline, towards the heat pump.

C448 Geothermal Heat Pumps: Bi-National American–Canadian Standard

The Ground Source Heat Pump Regulation outlines the requirements a person must meet to obtain a single ccsa multi-site environmental compliance approval and to do work on a vertical closed loop earth energy system. Does not apply for Individual household Applies and Must be Obtained Before installation for all other cases.

Please first verify your email before subscribing to alerts. Depending on circumstance, the Ministry of the Environment can offer assistance and notify other interested agencies to help reduce dangers to the site crew, well owner and the environment. Ministry of Natural Resources Regional Offices. For a direct exchange earth energy system, the standards Sections 5. Two tubes extend horizontally from the exposed basement into the excavation.

The holder of the environmental compliance approval is responsible for compliance and must take measures to ensure that the activities related to installing a vertical closed loop earth energy system comply csaa the requirements of the environmental compliance c4448. Earth energy systems should not be confused with high temperature geothermal systems over 50 degrees Cssa that obtain heat from deep within the earth to produce heat and generate electricity e. The main drawing shows cs DX closed loop system with multiple angled subsurface loops installed in boreholes that were drilled at various angles from one location under the lawn of the home.

If contamination, such as a hazardous waste, is encountered during the construction of a hole associated with an earth energy system, the person constructing the hole should stop work immediately to reduce serious dangers to the site crew, well owner and the environment. This figure is a schematic drawing showing neighbourhood solar thermal collection, geothermal storage and residential use of energy.

Subsection 14 1 of the Environmental Protection Act states that a person shall not discharge a contaminant or cause c4448 permit the discharge of a contaminant into the natural environment, if the discharge causes or may cause an adverse effect.

The diagram depicts a summer setting and represents heat taken from the residence into the water in the heat pump to cool the residence. All of the drawings show the tubing buried beneath the ground surface. Courtesy of GeoSmart Energy. A single story residential house is located cda the upper left area of the diagram.
