Prima Facie vs Deemed to satisfy compliance paths

Performance based approach – Professional Judgement

Based on project specific conditions Example – a stormwater attenuation strategy is designed to suit the sites hydrology and the

downstream capacity of existing infrastructure. Data inputs must be verifiable May be designed to limit states rather than safety factors The designer and certifier must demonstrate that the chosen solution provides compliance Reports must define scope clearly and finding must be objective and consistent, i.e based on

International normative standard methodologies.

Methods other than TGD can be used to establish compliance, provided detailed document s are provided by an appropriately qualified /experienced professional.

Prescriptive Guidance – TGD’s or referenced standards

Based on past Evidence Example – what is a 100 year storm what damage does it do. Can be applied to a wide range of building types and locations Contains safety factors to account for general applications Residual risk is considered to be negligible Warning: has limits to its applicability


System must be designed to carry the expected flow

Who determines the ‘expected flow’

Has the required depth of cover been set been provided

Has bedding and backfilling been detailed as per Diagram 8

Has the Benching been done correctly

Will all drains be tested for watertightness on completion



gradients at which foul drains should be laid, depends on flow

Fall = gradient x distance


Pipe gradients and sizes

Foul Water Drainage – Design overlap


Where foul drainage from a building is to be pumped, the effluent-receiving chamber should be sized to contain 24-hour inflow to allow for disruption in service.

The capacity of the receiving chamber should be based on the calculated daily demand of the water intake for the building.

Pump efficiency to be fitted with a suitable alarm system to alert the owner of any malfunction

Bedding and backfilling


Bedding and backfilling 3 types of graded granular fill used for bBackfilling, bedding graded material size Related to pipe diameter

No standing water in trench

Testing


Rocker Pipe - a short length of pipe, usually less than 1 metre, placed at the inlet/outlet of a solid structure, such as a manhole or building, to accommodate differential settlement between the structure and the drainage system.

Natural Ventilation (system 1) is appropriate below 3m3/m2/hr.

For test results below 5m3hr/m/sq in System 1 units you must increase the free area by 40%, how do you pre-emp this

Hole in the wall vents sized to a particular Square mm’s is a very crude calculation. A Habitable room needs 7000mm under 5 m3/mr/m2.

A sliding scale should be used based on flow rates 0.3 l/s/m2 minimum in a dwelling.

Natural Ventilation is predicated on an assumption that 5 pascals external vs internal pressure difference.

Intermittent fans increase this pressure to 15pascals, but only when the occupant runs the fans.

Airtightness

Holistic approach to ventilation and energy, sophisticated engineered solution.

Mechanical Ventilation systems can incorporate hundreds of meters of 4 inch pipe, sometimes flexible Fan isn’t sized to suit the resistance of the project duct rums.How is it verified?

Commissioning and verification is critical can you verify 30 l/s has been provided in kitchen using an anonometer.

Domestic plumber is not a ventilation specialist.Plumbing issue 12 years ago DIY plumbers using clip fit systems .

MHRV

FVENTILATION

Demand Control responds to the dwelling's ventilation needs in real time by making use of air pressure differences and humidity controls.

Humidity sensors are placed on both the inlets and exhausts to respond to room occupancy: the more people in the room the more ventilation you get.

The sensors consist of polyamide strips that expand and contract depending on the humidity levels in the room. Humidity levels are a good indicator of occupancy because people sweat, talk, shower and cook, all of which creates humidity. High humidity levels have also been correlated to low indoor air quality, in terms of carbon dioxide levels.

MEV or Whole house Extract types containing Mostly Demand Control Ventilation and Balanced Whole house Mechanical Heat recoverymake up 51% of the market.

•Background ventilators should be located in all rooms with external walls.•Once the total requirement has been calculated, at least 5000mm² equivalent area is required in each habitable room and 2500mm² equivalent area is required in each wet room.

SEAI Best Practice Guide Heat Pump TechnologiesEnsure installer provides you with a signed commissioning certificate and all the system documentation, provides a schedule of required maintenance and demonstrates to you how the heating system operates. The supplier / installer should also provide you with an operation manual in English that covers the operation and maintenance of the system

commissioning the heat pump is quite lengthy and involves several steps including:•checking the basic installation•making final electrical connections to the heat pump•filling the ground loop with the water/glycol heat transfer fluid•test running the pump components•setting initial heat pump controller settings•heating the contents of the 300 litre hot water cylinder using the in-built immersion heaters to bring it close to working temperature
