Victoria Quay - Scottish Office building in Edinburgh. The major issues are: daylight utilization and summer heat gains.
 

 

Office building for the Scottish Office. The building comprises a number of individual office blocks connected by an internal galleria. An individual block consists of shallow office accommodation, grouped around a central atrium. The case study focuses on the second and third floors adjacent to the central atrium.

Bearing Load construction

column system, concrete, steel construction

Building envelope

Sandwich construction including stone concrete 0.17 cm, air gap 0,055 m, glasswool 0.1 m and white concrete 0.17 m; U-value of the external walls is 0.32 W/m2K.


External windows are double glazed with standard 6 mm glazing. There are shading elements above the windows.
The roof is designed as an inverted concrete roof.

Lighting

On each level, six rows of luminaires are split between four rows of dimming fixtures (adjacent to the atrium and the south facade), and two rows of fixtures in the core, all on during occupied hours. The lighting is controlled by timed functions in the BEMS: off before 6:00, 25% on between 6:00 and 7:45 and fully on from 7:45 to 17:45.

Electrical appliances

The small power loads are above normal load density at 21 W/m2 and assumed to be on from 8:00 to 18:00 during weekdays.

Occupants

The occupied space density per person is 15m2 or 6 W/m2 (equivalent to 90W sensible heat emission) during the occupied period 8:00 to 18:00 during weekdays. It is assumed, that the building is not occupied at weekends.

Heating

The building is heated by radiators in the offices facing the atrium and adjacent to the south facade. Gas fired boilers are used for the heating supply. Major of heat losses is covered by heat gains from lighting and other casual gains.

Ventilating, Air conditioning

In the considered part of the building is displacement ventilation. A mixture of fresh and recirculated air is supplied to the floor plenums and tempered to 17C. The displacement ventilation can be used for night purge cooling and to augment natural ventilation. The building is designed to allow natural ventilation by openable windows in the occupied space. Atrium ventilation is controlled centrally. There is no cooling provision in the building (except for dining and computer rooms which are not included in this analysis).
