Design Services

We provide residential mechanical design services for heating, cooling and ventilation. A properly sized designed system helps mechanical contractors, builders and home owners improve comfort, efficiency, durability of equipment and improves air quality.

Our HVAC designs provide the proper documents for building permit applications, covering Sections 9.32, 9.33 and 9.36 of the National Building Code.

Why is it important to have a properly sized HVAC design from a certified design expert?

  • Maximum efficiency of the HVAC system.

  • Quiet operation.

  • Proper distribution of heating or cooling at all times of the year alleviating the problem of rooms that are too hot or too cold.

Heat loss calculations

Heat Loss/Heat Gain Calculations
Block load heat loss/heat gain calculations for new and replacement equipment provides proper equipment sizing for heating and air conditioning systems as required in section 9.33.5.1.1 of the National Building Code. This allows for proper sizing of the furnace and air conditioner units. When this equipment is sized properly, the house is more comfortable for the occupants and more efficient, resulting in less energy usage and lower utility costs.

Room by Room Calculations
Room by room heat loss/heat gain calculations for design of distribution systems is required in section 9.33.3.1.1 of the National Building Code. Going into this level of detail ensures comfort levels are even throughout the entire home. It ensures the proper amount of warm or cool air is supplied to each room, allowing for consistent temperatures and comfort levels regardless of where you are in the home.

Duct design

Duct Design for forced air heating and cooling systems as set out in Section 9.33.4.1.1 of the National Building Code. We use the HRAI Digest method. Duct design ensures the proper amount of air actually reaches each part of the home as calculated in the room by room calculations. Regardless of where you are in the home, temperature and comfort levels are maintained.

Mechanical Ventilation Design

Mechanical Ventilation Design is required by Section 9.32 of the National Building Code. This provides the removal of stale air from the home and replaces it with an equal amount of fresh air to ensure a healthy environment for the homes occupants.

ENERGY MODELLING

We provide energy modeling to demonstrate the efficiency of a new home before it is built. This is one of the methods used to demonstrate that the energy efficiency of a new home will meet the energy requirements of section 9.36 of the National Building Code.

At FM Residential we can help with your building permit application by qualifying your new build to either the prescriptive method or the performance method (energy modeling). This can be done to any of the new tiers in the 2020 National Building Code. Presently Saskatchewan requires all new homes to be built to tier 2 minimum.

 BLOWER DOOR TESTING

Determining the air tightness of a new home is one of the most cost effective ways to prove the efficiency of the home and can help move the house up the energy tiers. Many homes built today, if air tested, could qualify for tier 3 or more without changing the construction specifications. Air tightness of houses is measured in air change rate at -50pa and expressed as an ACH number.

We have the latest equipment in automated blower door testing that includes wind sensing technology and geotagging of the location.
