Why is Ventilation Important?
It needs to be defined and designed early on, as it is intrinsic to the health and wellbeing of the occupants and the efficiency of the home and it is very disruptive to add to an existing property.
How does convection work?
The first uses the principle of convection, or air buoyancy, where the warm, rising, air currents allow the movement of air out of the dwelling at high level and fresh air enters through trickle vents and air bricks, or purpose made air inlet ducts. These ducts are located in various locations around the dwelling, or in the passive ventilation unit. The air can be warm due to occupancy, with ducts often installed in chimney stacks, or it can also be designed into a vaulted area with lots of glazing to allow the sun to warm the space, causing the convection.
What is the minimum ventilation rate for a home?
The Domestic Ventilation Compliance Guide describes the whole house ventilation rate for homes as follows: 1 bed homes: 13 l/s, 2 bed homes: 17 l/s, 3 bed homes: 21 l/s, 4 bed homes: 25l/s, 5 bed homes: 29l/s but a minimum ventilation rate of 0.3l/s per m2 of floor area (including all floors) must also be maintained. These figures assume that only one bedroom has double occupancy and if there is a higher occupancy then we add 4l/s per occupant.
What is MVHR ventilation?
Mechanical Ventilation with Heat Recovery ( MVHR) is covered under System 4 of the Building Regulations, Part F. Heat Recovery ventilation provides fresh, filtered air, energy efficiency and a comfortable all year round climate.
Where is the centralised MEV system located?
The centralised MEV system is typically located in a loft space or hallway cupboard. Multiple ducts run from the kitchen, bathroom, ensuite and other wet rooms of a property to the MEV unit to simultaneously draw moisture-laden air from these wet rooms to control humidity levels. The ducts are balanced on commissioning by the installation engineer to ensure the right air flow is achieved in each area. As the air is extracted, fresh air enters the home via trickle vents and air bricks in the fabric of the building.
How does passive ventilation work?
An alternative passive ventilation system relies on wind pressure. Prevailing wind creates a positive pressure on the windward side of the building and a negative pressure is created on the leeward side of the building as the wind moves away from it. The combination of the positive and negative air creates an air flow through the home as it pushes from one side and pulls from the other. In leaky homes this effect takes away the warmth in the home very rapidly, but if designed properly it can provide a very good ventilation solution.
How many ventilation systems are there in a building?
There are effectively four different ventilation ‘systems’ that are described in Part F and any new build needs to comply with one of them to be passed by building control. Each of the systems has an implication on cost, disruption and overall energy efficiency of the property, so this is certainly something that needs to be detailed at the brief stage or you may end up with the system that you didn’t choose or one that does not work.
