RIAI / DEAP_3_2_screen_updates_draft / Start and other general amendments / ge / “New entry recording the purpose of the rating” - what is the reason for this entry, it could cause confusion and we see no gain. / Omit proposed amendment.
RIAI / DEAP_3_2_screen_updates_draft / Dimensions / te / Living room percentage is calculated as area but space heating is calculated as volume. / Change living room entry to volume or area and height.
RIAI / DEAP_3_2_screen_updates_draft / Dimensions / te / If number of stories is left void the value defaults as 0. / Default to have one or more pop up warning.
Number of stories should prompt for correction if number not entered or default to value 1.
RIAI / Dimensions / Very small houses should have some compensation in Part L compliance to acknowledge their actual lower energy use. / Very small houses should have some compensation in Part L compliance to acknowledge their actual lower energy use.
RIAI / DEAP_3_2_screen_updates_draft / Ventilation / te / Compliance of ventilation with Part F
DEAP should contain a tab to record details of ventilation provided and a facility to demonstrate compliance with Part F. / it would be useful for DEAP to contain a tab to record details of ventilation provided and a facility to demonstrate compliance with Part F.
RIAI / DEAP_3_2_screen_updates_draft / Windows / te / Solar gain not calculated
Adopt Passive House approach to maximise solar gain as main source of heat / Allow solar heat gain to be included in space heating. Link to internal heat capacity - thermal mass category.
RIAI / DEAP_3_2_screen_updates_draft / Water Heating / te / No allowance for electric showers.
Electric Showers are not recorded in DEAP / Provide for including energy consumed by electric showers.
Allow input for electric showers
RIAI / DEAP_3_2_screen_updates_draft / Lighting and Internal Gains / te / Percentage of low energy fixed lighting outlets does not reflect energy use accurately. Multiple outlets per room in one dwelling versus single outlets per room in another dwelling could be calculated as the same in percentage terms. / Change from percentage to actual number or outlets.
RIAI / DEAP_3_2_screen_updates_draft / Lighting and Internal Gains / te / No allowance is made for extended periods of artificial lighting in rooms with low daylighting.
The daylight factor should be increased to 5%. / Provide a means for including daylight factor in artificial lighting calculations.
The daylight factor should be increased to 5%.
RIAI / DEAP_Manual_Version_3_2_draft / Various / ge / This document states in several areas that further guidance is provided in the Frequently Asked Questions and Technical Bulletins available on the SEAI website and we recognise that these are valuable sources which will be continually updated, however this requires referencing many documents and sources to gain all the necessary information. / Compile all the currently available guidance into this manual. Future additions to these sources can be incorporated into future revisions of the manual.
RIAI / Dimensions
Building elements / Reduce thermal comfort parameters to 18 degrees. Better performing buildings deliver greater sensation of thermal comfort.
RIAI / Energy Requirements / ge / The requirement for on-site renewables be altered from an absolute figure to a proportional one, i.e. that 10% of the energy demand of a dwelling is supplied by renewables. / The requirement for on-site renewables be altered from an absolute figure to a proportional one, i.e. that 10% of the energy demand of a dwelling is supplied by renewables.
RIAI / Energy Requirements / ge / Micro renewables are an expensive abatement technology and regulations which would encourage their installation in non-optimal locations should be avoided. / We would recommend that renewables be required in 'all reasonable circumstances'.
RIAI / Energy Requirements / ge / Solid-fuel stoves and heat pumps should be excluded from the list of renewable technologies because both are only partially renewable, dependent on circumstance, and therefore should be treated the same. / Solid-fuel stoves and heat pumps should be excluded from the list of renewable technologies because both are only partially renewable, dependent on circumstance, and therefore should be treated the same.
RIAI / All / general / Various / ge / The MPEPC and MPCPC methodologies cause vastly varying levels of energy efficiency to be required of different dwellings in achieving compliance. In particular, it causes a bias against buildings with an efficient form. / Replace the MPEPC and MPCPC ratios with a fixed maximum energy use in terms of kWh/m2/yr and fixed maximum carbon emissions in terms of kgCO2/m2/yr.
RIAI / All / general / Various / te / Some of the parameters of the reference 2005 dwelling adjust to follow those of the actual dwelling being assessed resulting in inconsistencies with regard to compliance. / All parameters of the reference 2005 dwelling should be fixed so as to show a direct and actual comparison between dwellings being assessed.
RIAI / All / general / Various / te / Part L compliance will require alternatives to the standard u-values and therefore practitioner will have much more occasion to calculate these / DEAP software should include a tab for recording fabric build up and calculating U-values.
RIAI / All / general / Various / te / New thermal bridging requirements of Part L necessitates calculation. / DEAP software could include a tab for recording and calculating thermal bridging.
RIAI / Audit system / Penalties / ge / The same penalty applies if the assessor visited the building or not. / Have additional penalty for assessors who have not visited buildings.
