Condensation Risk – Impact of Improvements to Part L and Robust Details on Part C -Interim report number 7: Final report on project fieldwork

This report sets out, in draft1, the results of the fieldwork phase of research into the impacts of the 2002 revisions to Part L of the building regulations (Approved Document L1 - DTLR, 2001), and the adoption of Robust Details (RDs - DEFRA 2001) on the extent of condensation risk in the construction of dwellings (Oreszczyn and Bell, 2003). The objective of the fieldwork was to explore the practical application of the revised Part L and its associated robust details by housing developers. This was done through a qualitative evaluation of the design and construction of 16 housing schemes designed in accordance with the revised part L and making use of robust details2. The results of the analysis are to be used to enable condensation modelling that takes into account not only the guidance of robust details but also the way in which construction details were actually designed and, perhaps more importantly, constructed. To this end the report identifies 7 areas of construction detailing (yielding some 15 separate detail models) that are to be included in the condensation modelling phase of the project

Airtightness of buildings — towards higher performance: Final Report — Domestic Sector Airtightness

This report constitutes milestone D11 — Final Report — Domestic Sector Airtightness of the Communities and Local Government/ODPM Project reference CI 61/6/16 (BD2429) Airtightness of Buildings — Towards Higher Performance (Borland and Bell, 2003). This report presents the overall conclusions and key messages obtained from the project through design assessments, construction observations, discussions with developers and pressurisation test results. It also summarises discussion on the airtight performance of current UK housing, the implementation and impact of current and future legislation, and identifies potential areas for future work

Shining examples of cost-effective energy and carbon emissions optimization in building renovation (Annex 56)

"Energy in Buildings and Communities Programme, March 2017"This brochure is a selection of successful realised demonstration projects within IEA EBC Annex56 partner countries that highlights successful solutions and provides general findings, similarities and differences emerging out of the demonstration projects selected in the participating countries. The ?ShiningExamples? are gathered mainly for motivation and stimulation purposes, highlighting the advantages of aiming at far reaching energy and carbon emissions reductions, being still cost effective. The focus is to highlight advantages and innovative (but feasible) solutions and strategies.info:eu-repo/semantics/publishedVersio

Infiltration Characteristics of Swine Finishing and Gestation Buildings: Review and Quantification

Infiltration is an integral part of the ventilation system and process. Infiltration affects the quality of the barn environment and can also increase the winter heating cost. Precise data on infiltration is very important in the design of ventilation systems for animal barns. Many researchers have suggested that ASHRAE’s ‘crack’ method is not suitable for predicting infiltration of animal barns. Among the available methods, pressurization methods are commonly used in infiltration quantification and the power law model gives the best prediction of the infiltration rate. For this research project, 18 swine finishing rooms and three swine gestation rooms were tested for their infiltration characteristics. At 20 Pa pressure difference across the room envelope, the average as-is leakage rate for the 18 swine finishing rooms was 6.43±1.68 ACH; whereas, the average leakage rates through curtains, fans and other components were 1.47±0.71 ACH (about 23% of as-is), 1.63±0.77 ACH (about 25% of as-is) and 3.33±1.23 ACH (about 52% of as-is), respectively. Of the three filtered sow barns that were monitored where air tightness is very important to prevent entry of viruses like PRRV, the more conventional designed facilities, where filters are only added to the ceiling attic inlets, were not very tight (roughly 2 ACH). A much tighter barn, with an infiltration value of 0.1 ACH, was obtained in a specially designed large sow building where the filters were built into the ends of the building and an extensive amount of foam sealant was used

hybridGEOTABS project : MPC for controlling the power of the ground by integration

GEOTABS is an acronym for a GEOthermal heat pump combined with a Thermally Activated Building System (TABS). GEOTABS combines the use of geothermal energy, which is an almost limitless and ubiquitous energy source, with radiant heating and cooling systems, which can provide very comfortable conditioning of the indoor space. GEOTABShybrid refers to the integration of GEOTABS with secondary heating and cooling systems and other renewable and residual energy sources (R2ES), offering a huge potential to meet heating and cooling needs in office buildings, elderly care homes, schools and multi-family buildings throughout Europe in a sustainable way. Through the use of Model Predictive Control (MPC), a new control-integrated building design procedure and a readily applicable commercial system solution in GEOTABShybrid, the overall efficiency of heating and cooling will be significantly improved in comparison to current best practice GEOTABS systems and its competitiveness will be strengthened. The present paper is the first of a series that first introduces the hybridGEOTABS project and then specifically focuses on the control-related aspects of the hybridGEOTABS solution, the MPC, providing some interesting insights of its potential development
