Objective
To demonstrate, in a library building, techno-economic optimisation of a highly insulated glazed atrium integrated with an innovative low heat loss building construction. Both the glazing system and building construction are formed from standardised modular components. The external appearance of the building will maintain a coherent architectural style and articulation. Monitoring will be undertaken for three heating seasons. Data will be passed via modem to a dedicated computer based data analysis and interpretation centre. Performance of the system will be disseminated via reports, workshops, an internet home page and a video.
1. Innovative technology - When using a building fabric with such low thermal heat losses (0.19 W/m2K - 0.27 W/m2K) the glazing losses become a much larger portion of the total envelope losses. There has been no demonstration of such a thermally efficient (O.4 W/m2K) glazing system optimally integrated to such an energy efficient building fabric in a non-industrial building within the European Community. Pre-heated ventilation air will be circulated from the atria to the adjacent occupied study spaces to ensure adequate circulation of pre-heated ventilation air during the heating season. During late spring and early autumn, when excess solar gains may ensue, the solar pre-heated air from the atrium will be diverted. It will be circulated through, and subsequently exhausted from, an appropriately sized internal mass element. Overheating during the summer will be minimized by the appropriate use of external shading devices.
2. Context in which the technology is operating - In 1994/5 the University attended 8186 full-time students, and the library had a total of 701.072 users during the same period. The portion of the building under consideration and the atrium will occupy 1474m2 (excluding external areas, i.e. car parks and hardstanding areas, etc.). The periods of occupation are from 9:00 am until 10:00 pm Monday - Friday and 10:00 am to 5:00 pm Saturday.
3. Economic aspects of the technology
Cost of fuel saved per MWh £20.00 £499.64
Cost of fabric energy savings £5,237.60
Total £5,737.24
Cost of high performance glazing 166m2
for Atrium and 344m2 direct gain £43,668.75
Additional cost of fabric £52,760.00
Total £96,428.75
The minimum operative life of the installation will be 20 years. The economic viability will improve upon future commercial exploitation of the technologies as increased economies of scale in manufacturing ensue.
4. Monitoring - The performance of the innovative building fabric will be investigated as part of the overall system of the building. In both cases the monitoring will set out to determine not only the energy performance, but also the mode of operation, i.e. the interaction between the occupants and the building. Continuous objective monitoring will be undertaken which will furnish data for semi-annual and annual energy assessment. The monitoring strategy will be non-invasive using advanced telemetry and will quantify performance in terms of heating, lighting, and ventilation loads.
