NZEB  Requirements For Non Domestic buildings 

# data[].attributes.body
some of the key requirements are.

1) Limiting heat gain .

2) The building is properly designed to limit cooling .

3)Limiting heat loss from pipes ducts and other vessels. used for the storage or transportation of heated water or air.

4)limiting heat gains.

5)providing energy efficient lighting systems.

6)providing the building owner with sufficient information.

7)cost must must be updated in line with new energy. performance requirement ratings when renovating a building.

Nearly Zero energy building or NZEB is a standard for energy efficiency in buildings, including non domestic ones like schools, offices and industrial facilities. The overall goal of NZEB is to reduce a buildings energy consumption to a minimum.

Minister Simon Coveney introduced NZEB on the 20th of January 2017. Once NZEB was brought into law an amendment in the building regulations had to be made in order For NZEB to be adhered to when designing or renovating buildings.

NZEB in non domestic building include energy efficient materials and structures that are assessed by the amount of energy used and the renewable materials used in construction. take for example a triple glazed curtain wall which will allow more light which will also provide heat into the building in turn improving energy performance and reducing the dependency on electricity.

In Ireland, the NZEB regulations are mandatory for newly constructed commercial buildings; however, existing structures will only need to comply with the criteria if they begin to undergo renovations.

This is a portal frame my uncle built a couple of years ago. The shed is built from steel and shuttered concrete walls. This method of construction was chosen as it is quick to assemble and it provides a large open space with no columns or supports that interrupt floor space.

If this shed was to be used as a work shop where the temperature has to be kept above a certain level, the wall and roof spaces could be filled with insulation and covered with either plasterboard or plywood. A layer of DPC would be needed in order to stop condensation from the tin from destroying the insulation. This would improve the buildings energy rating quite a bit.

According to the NZEB standard, a building's energy performance must be extremely high. Energy from renewable sources should account for a large portion of the nearly nil or extremely low amount of energy needed.

The overall dimensions of the shed are 80ft x 40ft x 14ft for a shed of this size solar panels could be used as its source of power as is uses minimal electricity this cuts out the need for it to be connected to an external power source. As well as that there are gutters on each side of the shed that feed a tank that is used to run a tap the shed is also connected to a water mains but the mains are only used if the tank is low. This allows the shed to have a fairly low energy rating.
