The DSSR ethos is to provide the client with a low energy, low carbon impact, well designed, capital and revenue cost efficient building. In addition to our core M&E services we can add value to any project by providing the following specialist services.

CFD

DSSR have an in-house specialist in the use of Computational Fluid Dynamics (CFD) in modelling of the built environment.

CFD Computational Fluid Dynamics (CFD) allows a more detailed examination of air velocity, air temperature, humidity, thermal radiation, thermal comfort and air quality within the built environment than can be obtained from thermal models alone.  For example, instead of the room average air temperature provided by a thermal model, CFD models can resolve the temperature distribution across a room:  the thermal stratification resulting from a displacement ventilation system, or the cool downdraft, and resulting thermal comfort, next to a window during winter.

Because CFD can be used to calculate these variables on a much finer scale than a thermal model it can be used for building design optimisation and building physics problems that are out of the scope of thermal models.

Thermal Modelling

Thermal Modelling is an expertise offered by DSSR which can add value to the design by helping to reduce capital and life cycle costs, reduce CO2emissions and provide environments which occupants are satisfied with.  We carry this out using our modelling software of choice which is the  accredited dynamic simulation software IES VE.

On any design project the RIBA Stage A / B is normally the domain of the Architect and is generally the stage where conceptual building layouts are being developed. This is traditionally seen as being too early to be passed to the Engineers to allow the structure and services to be designed. However, in recent years DSSR have been providing more assistance to developers and their design teams during these early stages to help maximise the building design in terms of energy and environmental design.

At all stages of the design we can provide dynamic simulation modelling as a means of reviewing the design and simulating the expected building energy requirements and in turn building carbon dioxide emissions.

Sustainability / BREEAM

In addition to the traditional Mechanical and Electrical Design Services which have been provided by DSSR , we are also in a position to offer consultancy advice on all elements of sustainable design.

DSSR has a dedicated sustainability team that as well as being able to undertake detailed feasibility studies for low or zero carbon technologies, includes BREEAM Assessors who can produce the initial BREEAM pre-assessment to ensure that the required target is achievable on a project. DSSR strive to have a positive impact on the world, putting sustainability at the core of what we do. We believe that delivering sustainable buildings for our clients and for future generations will make all our businesses stronger in the long run.

A member of the Sustainability Team will be involved from the outset of a project, assisting with the preparation of the brief, where they will encourage and support the design team, specifiers and other key stakeholders to set sustainability targets and to develop an integrated design and construction resulting in a truly sustainable building.  The intention is to use the current BREEAM 2018 New Construction Scheme as a framework for establishing, agreeing and achieving the desired level of sustainability performance, with a target of meeting Best Practice Levels that will put this development into the top 10% of sustainable buildings.

High Voltage

DSSR specialise in a range of High Voltage services, including design for open or closed ring configurations, protection studies for HV through to LV protection devices and high voltage generator installation design and operation strategy, also in the investigation of complex operational problems associated with electrical infrastructure failures from HV systems through to LV networks.

DSSR’s services also extend to the replacement of complex obsolete SCADA systems supporting and controlling HV Networks supplying mission critical instantiations with up to date controls systems using IEC 61850 protocol. The services provided by DSSR are supported by HV AP certified staff.
