Assessment Overview

You work for a medium-sized Building Services company (GBS Building Solutions) with nine offices across the UK. Their services cover areas such as planned preventative maintenance, mechanical and electrical maintenance, HVAC systems, building management systems, energy control management, Smart Home solutions, plumbing, and more. GBS Solutions is  involved in this exciting project  in a growing,  mixed-development area in Coventry.

GBS Solutions is contracted to be the Facility Managers for an 8-storey mixed-use (office and residential flats) building, as well as to install BMS/Smart Home systems across 24 units of small modular residential buildings in the same neighbourhood as part of a comprehensive upgrade. As a Building Services professional, your Line Manager has tasked you with preparing a report. You are required to prepare a 5,000-word report on essential building services, facility management, and building management systems (BMS). This report should be in two parts:

1. Your recommendations/proposals for essential building services and their Facility (building services) Management plan, for the 8-storey mixed-use (office and residential flats)
2. Your recommendations/proposals of BMS, HVAC, and digital twin systems for the 24 units of small modular homes, as well as data visualisations to support the BMS installations process in the residences.

Part One: Building Services and Maintenance Management [2200 words]

Your tasks

Research the essential services for a mixed-use office/residential building to give you an idea of what to recommend to your Line Manager and the stakeholders. This part should include:

1. Building Overview: Description, Number of Floors, Occupancy Type, etc.
2. Assets inventory, i.e., what are the major building services required in the building? [these must be relevant, researched, and referenced]. For each asset/building service, provide a description of its characteristics and importance, i.e., why you are recommending it.
3. Maintenance Schedule: For each asset/building service, propose a reasonable maintenance schedule, including any testing to be done, and referring to relevant guiding regulations. Also include what type of maintenance management it belongs to.
4. Propose a security plan to include access control, surveillance, and alarm systems.
5. Propose a plan to include sustainability initiatives in the use of this building. Examples include: Energy Efficiency Measures: LED Lighting, Energy-Efficient HVAC Systems, Waste Management: Recycling Programme, Composting, etc.

Use a table to summarise your recommendations, and maintenance schedules.

Part Two: BMS for the 24 Residences [2200 words]

For the 24 modular residential homes, you are required to provide some recommendations to support the functioning of the BMS/HVAC system. To better understand current energy trends and cycles, your team decided to install simple IoT sensors in select homes to collect several measurements including temperature, humidity, and occupancy, for one week. These measurements, as well as a BIM model, are collated in a folder provided to you.

Your tasks

1. You have been assigned to the ‘CMA 5002 Smart sensor dataset’. Open the file, it contains several measurements collected with the IoT sensors. You are to study ONLY the temperature data and report your findings and recommendations. To do this:
   1. Visualise the data by plotting them on a clear, suitable graph, with date/time on the x-axis and temperature on the y-axis. These must be shown in the report.
   2. Comment on the temperature values, for example, on whether they are generally too high or low, or on its variations, etc.
   3. Based on your thoughts, recommend upper and lower thresholds, i.e., maximum and minimum temperature setpoints suitable for the room(s), with which the BMS/HVAC system can be preset. Justify your decisions.
   4. Using your recommended thresholds, add horizontal threshold lines to the graph, and identify the times they were breached (e.g., between 9am to 11am on Monday). You can use a table to add this to the report.
   5. Discuss and summarise your data visualisation.
   6. Briefly describe the HVAC system recommended for the residences (e.g., centralised, all-air system (choose whichever, but discuss its suitability)), and its major components.
   7. Explain fully the Open (Feedback) loop mechanism that will be used by the BMS/HVAC system to regulate the home temperatures to these recommended values in (c), identifying and describing key technical components and their roles, like sensors, controller, controlled device, controlling variable, and controlled action.
2. Give a brief overview of how a BMS/Smart Home system would function in this residence. Recommend and describe features for the Smart Home system; think about: data collection (using installed sensors), access control, energy management, lighting automation, occupancy monitoring/tracking, security and safety, condition-based/predictive maintenance, etc.
3. With a smart home system and BIM (Building Information Modelling), we have all the key ingredients for a digital twin, so you should recommend this in your report too.
   1. Describe and introduce the concept of digital twins, including its advantages, why we need them, and how they are useful in this project.
   2. How can a BMS/smart home system support BIM models to enable the development of digital twins for the residences in this project?

NB: Your report must include an Introduction and a Conclusion, 300 words each.
