Green Real Estate is an Irish real estate developer with a large portfolio of commercial, retail and residential properties. The company’s recent development on the corner of Dublin’s Dawson Street and Molesworth Street consists of 11,000m2 of new office build, ground floor retail and including an underground car park and sub-basement level plant rooms.
The mixed-unit development accommodates retail units at lower ground floor and ground floor and commercial office space on the upper floors. The offices have been designed to be flexible with up to 2 tenants per floor.
Axiseng were commissioned by Green Property to deliver best-in-class building services solutions for Grade A office space to what is a prime location in Dublin city centre. The office areas would need to be fully air-conditioned with careful consideration required when selecting central plant due to site constraints. To ensure that the lettable area is maximised, most of the plant is placed in the basement to minimise any noise issues. The roof plant is limited to dry air coolers only within a small sunken plant area.
The services solutions to the retail spaces needed to flexible so as to allow multi-tenanted use when finally delivered.
The building achieved a LEED Platinum rating. This was achieved by the use of technology such as rainwater harvesting, as well as high efficiency HVAC, lighting and water fixtures to reduce the use of natural resources. Renewables were provided in the form of PV panels at roof level. Only refrigerants with minimal environmental impact run through the cooling systems. An intensive green roof promotes local biodiversity, while retaining storm water – thus reducing the burden to sewage systems.
The basement area houses the AHU and life safety generators. Significant consideration was given to access and maintenance of these items of plant. A tracking exercise was completed to ensure that all maintainable elements could be accessed via the stairs and cores. For major plant replacement a soft spot was created in the sub-basement allowing these to be brought to the basement car park. From here these can be brought to ground floor via the 4000kg car lifts. As part of this solution lifting beams were also included in the slab above the soft spots to facilitate lifting of this equipment.
The building was also altered heavily to suit incoming tenants. The building was originally intended to house retail units at ground floor level. During construction and due to property demands in the location this was changed to restaurant and cinema spaces. These changes required changes to the services to include additional natural gas supplies, kitchen extract routes and alterations to power.
The building is now home to significant tenants including Barclays Bank and The Ivy Restaurant.
