In one of the best locations in North Sydney, 100 Mount Street is a new development offering 42,000 sqm of architecturally designed office space across 34 levels.

Built for Dexus by Laing Orourke and designed by Architectus , the building features an inviting lobby with 8m high ceiling, harbour views from its eastern and southern aspects and on-site retailers. It has achieved a 5-star Green Star and 5-star NABERS Energy rating.

The ground floor with its impressive ceiling heights and enormous glass facades posed some problems for the mechanical engineers in terms of efficient heating. The ground level features a Lobby, Restaurant and through site link that results in constant foot traffic to the street frontages on two sides with cold air infiltration in cooler months.

Cundall was engaged to produce a Ground Floor Thermal Comfort report that recommended the use of hydronic floor heating to provide consistent warmth to the occupants. RHCS has successfully accomplished this with its RDZ 20mm industrial hydronic system embedded in the entire ground floor slab. Supplied with heating water from the central services and distributed through 2 manifolds, the system is efficiently managed by the Building Management System.
