Transpired Solar Collectors (TSCs) are a relatively new solar energy technology to the UK building-integrated renewable market. Since first TSC was integrated with profiling mill in County Durham 2005, further 19 commercial installations have ensued and combined absorber area totaling over 12,500 m2. Wales England home some architecturally technically innovative designs. These include one of world's largest TSCs, Cassette-Panel array special high-absorptivity selective coating diurnal...
Occupant behavior has an important impact on building energy consumption, and the accuracy of occupant model directly affects reliability consumption simulation results. Ultra-low buildings are crucial to achieving conservation carbon dioxide reduction in China. In order effectively promote development ultra-low Hot Summer Cold Winter Climate Zones. where most residents adopt a “part-time, part-space” pattern intermittent use behavior, solve problem poor indoor thermal environments high...
This paper presents the energy and environmental performance of whole house systems implemented in six 1970s bungalows South Wales, owned by Swansea Council. The objective was to reduce demand carbon emissions, maximise renewable supply whilst ensuring a comfortable affordable home for residents. system each involved installation combination passive active low solutions. Detailed monitoring carried out year before more than 2 years after work, annual figures have been validated normalised...
This paper presents the results for operating energy performance of smart operation a low carbon region (SOLCER) house. The house design is based on ‘systems’ approach, which integrates building technologies electrical and thermal systems, together with architectural design. It concept ‘energy positive’ buildings, utilising renewable systems form part envelope construction. describes how model HTB2, range additional ‘plugins’, has been used to simulate specific elements overall Measurement...
This study analyses the parameters concerning performance of Transpired Solar Collectors (TSCs)and offers a monitoring methodology that addresses some potential errors and uncertainties, including instrumentation use. The also investigates three TSCmodules equal area but different dimensions compares their efficiencies by altering several parameters. cavity systems is monitored for fan velocities wind directions. experiments took place outdoors in order to simulate real life installations.
Abstract This paper presents the design of a monitoring protocol to support retrofit strategies and drive evaluation low carbon house. Monitoring is used during pre-intervention stage facilitate decision-making process, as well in post-intervention evaluate performance building systems. The first phase refers diagnostic tool with view reduce uncertainty suggested solutions by providing real measurements evidence on conditions, comfort, systems occupants behaviour interactions. second...
Abstract European governments have set ambitious retrofitting targets driven by the commitment to reduce greenhouse gas emissions at least 80% 2050. The United Kingdom has oldest housing stock in Europe, with over 2/3 of dwellings built before 1976, when building regulations started include energy efficiency. This raises concerns carbon emissions, health, comfort and running costs, government’s initiatives for significant improvements. Deep using innovative technologies respect aesthetics...
A convenience store is a common building type in Wales, which has potential to achieve carbon emissions reduction through practical retrofit strategies. However, there lack of studies conducted address the low for these stores. Easy access into essential, however an open entrance will allow uncontrolled external air entering internal space. During heating seasons, this results difficult heat spaces due cold freely penetrating and leaving premises. significant amount energy wasted up large...
This paper presents a case study of neighbourhood low carbon energy system designed for five off-gas rural dwellings in the UK.The employment aims to improve efficiency whole site, reduce dependency on heating oil or LPG houses, maximize renewable usage and minimize fuel poverty through affordable investments.System design is discussed built site survey, on-going monitoring validated modelling.Simulation carried out dynamic model HTB2.A ROI analysis used examine long-term cost-effectiveness,...
