The field of thermal comfort surveys has recently expanded to other areas such as vehic- les and external spaces. An area that has not been examined is boats. This research will attempt to approach thermal comfort conditions in boats and establish a background for thermal comfort surveys in boats generally. The first part took place during the summer months of the year 2003 in Greece under real conditions. Several boats took part and also people with different characteristics such as age, sex and weight answered the questionnaires.
In built environment assured access to sun is important because of the quality of life and because of the energy benefits. We can find a great number of historical precedents of respecting this issue. In Slovenia traditional settlements of the Karst are a model example. In this paper we investigated the Karst settlement of Kobjeglava. We studied the disposition of buildings with respect to cooling. We used the solar volume method for assessing the urban plan and estimating the solar access.
The current environmental data and mainly the concern on the exhaustion of not renewable sources of energy dictate the need that the human activities should take place in the frame of sustainable development. Today, it can be achieved in the building sector and in general in the structured environment, via methods such as the one of high environmental quality (dmarche Haute Qualit Environnementale) and the one of Ev (Environmental Value).
In this study, a thermal-network model is employed for the determination of the characteristic thermal inertia factors and more specifically the decrement factor f and the time lag ?. These parameters are very important, especially during the warm period of summer (when passive cooling is essential), when a periodic thermal wave propagates through a walls cross sectional area, from its outer to its inner surface.
This paper describes a component of ongoing research that deals with planning and design strategies relevant to sustainable and low energy development. In this paper the particular status of the city of Seoul in Korea is investigated and analysed. The situation that applies in the city is a combination arising from national policies, city level interpretation and local level action. Seoul is compared to several other cities and the actions being taken.
Regular escalation of the state electricity price gives an impact to the increase of operational cost of any high-rise building in Indonesia. To be a rental office, the twin 31-floor buildings of Jakarta Stock Exchange (JSX) or Bursa Effect Jakarta (BEJ - in Indonesian terms) had no exception. The twin buildings were suffered from the impact of the state electricity price escalation. To reduce the bill, the building manager had to reduce the buildings energy consumption, and to consider tenants necessities for indoor comfort at the same time.
Existing advanced and sophisticated building systems combined with emerging IT technologies create the opportunities for e-based energy management. Driven mostly by the deregulation of energy market, e-based energy management systems have the potential to help both energy utilities to manage power load and reduce peak loads and end-users to reduce their consumption and possibly increase their comfort.
The cellular method for optimal shading design recently has been implemented as a plug-in for the Ecotect software (Fig. 1). This is a significant step since it enables designers to optimize shading devices based on predicted indoor hourly thermal requirements for shading and solar gain. These requirements are determined from predicted hourly heating and cooling loads or fluctuating internal comfort levels. The method comprises a unique process of projecting and accumulating this information onto numerous theoretical cells of proposed shading devices or any other outdoor locations.
In this paper, a new approach for energy consumption and peak demand predicting in buildings is shown. The method is based on a mathematical model of load curve and energy curve. This model is obtained after classification of typical curves using a multivariate technique called Cluster analysis. The performance of this predictor was evaluated using real data. The achieved results demonstrate the good precision reached with this system.
CLEAR [1] is a web-based interactive teaching package on low energy architecture and human comfort. It was developed by the Low Energy Architecture Research Unit, LEARN [2], of the London Metropolitan University with the collaboration of European and international academic partners. CLEAR is available on the Internet and may be used freely and without registration by everybody interested in the field. The development of CLEAR is based on the earlier DayMedia [3] and MulCom [4] packages, and is part-funded by the European Commission.
