HVAC
HVAC, which stands for Heating, Ventilation, and Air Conditioning, is an essential component of modern indoor comfort. Whether you’re at home, in the office, or in any other indoor space, HVAC systems play a crucial role in maintaining a comfortable and healthy environment regardless of the weather conditions outside. At International Green Building, we specialize in providing top-notch HVAC services.
We deliver the complete plans and calculations for your building permit application such as providing heat loss and heat gain calculations, Duct design, and drawings. ventilation design summary and HRV/ERV design. We offer tailored solutions for both residential /commercial/ industrial spaces. With our experience, we design and select the correct equipment and duct sizes in order to remain cost and time efficient.
Simulate annual Energy- Heat Loss Gain Calculations
In Ontario, Heat Loss Gain Calculations are a Building code requirement for Residential/commercial/ industrial Mechanical Design. They are used to determine the heating and cooling needs, by calculating the energy required to heat a building in the winter and cool it in the summer. They are a Primary Component of HVAC Design and are the basis for HVAC System selection.
Accurate calculations and analysis are necessary to correctly size system components. comfort, efficiency, and reliability are closely related to this correct sizing. When equipment is oversized, efficiency is reduced, operating costs soar and climate control over the building is impacted. Correct equipment sizing is vital for system efficiency and short and long-term reliability.
Where the ratio of gross area of windows, sidelights, skylights, glazing in doors and sliding glass doors to the gross area of peripheral walls measured from grade to the top of the upper most ceiling is more than 22%, the performance level shall be measured based on the simulated annual energy use of the building by simulate software such as HOT2000.
Heat Pump
A heat pump helps keep your home warm in the winter and cool in the summer by moving heat from the outdoors to indoors and vice versa. Heat pumps work all year round to ensure your comfort. Heat pumps do a lot more than just heat or cool your house; they can help improve indoor air quality and humidity levels throughout your home.
The heat pumps are ducted and ductless. Ductless heat pumps, also known as mini-split heat pumps, consist of an outdoor compressor unit and one or more indoor air-handling units.
Ductless systems provide ideal heating and cooling solution for homes without existing ductwork or where installing ductwork would be impractical.
VRF (Variable Refrigerant Flow) Heat Pump Systems
VRF continually adjusts the flow of the refrigerant to each indoor unit to provide heating or cooling. This improves the system’s overall efficiency, but since VRF systems are considerably more powerful and complex, they carry higher upfront costs.
The main difference between the VRF Heat Recovery and Heat Pump system is that the VRF Heat Recovery uses the heat which allows for simultaneous heating and cooling.
