Enniskerry Road Social and Affordable Housing scheme in the final stretch

This 155-residential unit development in Stepaside, Dublin is nearing completion and will shortly be handed over to clients, Respond and Tuath, for occupation.

The stunning development is nestled in the foothills of the Dublin mountains and will provide a mix of social and affordable housing to the south Dublin area. Managed jointly by Approved Housing Body providers, Respond and Tuath, the residential units include a mix of apartments and terraced housing, whilst a small office and community facility has also been included in the development. Waterman Moylan provided multidiscipline engineering services for the project.

The scheme incorporates a landscaped open space to the east of the apartments, providing an amenity area for residents. This accommodates a stream along its southern boundary, which has been retained along with the established natural tree and shrub growth lining the banks. A surface water attenuation tank is located beneath this area, and an integral flow control on the outfall to the stream ensures discharge of surface water is constrained to greenfield runoff rates.

In a boost to the development’s sustainability credentials, apartment heating and hot water is served via a district heating system. This is run by an energy centre incorporating combined heat and power (CHP) units, air source heat pumps and gas fired boilers to provide a low carbon, energy efficient heating solution. Electricity generated by the CHP is used to supply the heat pump and meet the site’s other energy demands and any ‘waste heat’ is captured and utilised by the heating system. The heat pumps are then supplemented by the gas boilers to meet peak loads.

Architects, ABK, were heavily involved with our mechanical engineers in maximising energy efficiency from the outset of the design process. They ensured there was a focus on optimising the building fabric, seeing elemental u-values exceed minimum compliance standards, while thermal bridging and air tightness detailing have been prioritised throughout. The combination of the excellent building fabric performance and the efficiency of the heating and ventilation systems have combined to deliver dwellings that perform to the highest environmental standards with BER ratings from A2.

Waterman Moylan’s Building Services Associate, Margaret Dolan, commented: “We have really enjoyed working with the client team on this project because, as managers and operators of residential complexes, they have a very clear vision of how they want their properties to be serviced. This allowed us to develop the building services and management systems design at an early stage and to make sure they were fully integrated with the architectural and structural layouts, resulting in a higher quality finished product.”
