A Procedure to Evaluate the Indoor Global Quality by a Sub Objective-Objective Procedure

This paper proposes two complementary procedures for assessing the indoor global comfort: the first one, prevalently objective, is based on the acquisition of microclimate measured data and computed subjective values; the second one, that is purely subjective, uses a questionnaire drawn from the ISO/DP 10551 Recommendation. An application to some lecture-halls is here showed

Experimental Evidence on the Thermal Performance of Opaque Surfaces in Mediterranean Climate

The thermal insulation of buildings, intended as wrap feature which determines the dispersion of heat, the reference parameter is necessary to contain the thermal losses during the winter season. The transmittance of the opaque components, used as an indicator of the energy quality of a casing, together with the overall coefficient of dispersion, represents a proper descriptor of the behavior during the heating season. However, if a strong insulation in winter conditions brings only positive effects, the same cannot be said for the summer conditions. A high value of the insulation in the casing is convenient only when the gains free, either in the form of solar contribution that of endogenous heat, are controlled and restricted. From the national transposition of the 2002/91/CE legislation up to the 2010/31/EU on the energy performance of buildings, performance values are set very restrictive transmittance of opaque surfaces that both of those transparent to the new buildings. The same does not happen for the thermophysical characteristics able to implement strategies for the control of solar radiation during the summer period, the fluctuations in external temperatures during the summer period. This article shows some experimental evidence of the effects on transmission rate and density of the opaque elements of the buildings carried out on a case study of a representative building of climate-Mediterranean summer: The study verify the results produced by increased insulation of the building envelope on energy performance of buildings during the summer through indicators such as temperature and energy consumption to maintain the same constant with respect to the prescribed values.

A Case Study to the Evaluation of Global Environmental Quality, Concerning Thermal, Acoustic and Atmospheric Conditions of Urban Areas

In this paper we propose an operative procedure aimed at assessing and check the global environmental quality in the urban areas. This methodology is set up by using an ergonomic approach that analyses the interaction man-environment in terms of cause-effect and uses information and data from various sources contributing to the formation of discomfort degrees.[1-2] The representation technique by normo-grams is used for showing some applications executed along the urban territory of Palermo and allows to evaluate very simply all the parameters involved in human comfort. This paper is divided in 5 sections, after the introduction in section 2 a review of the principal simple and complex indexes is presented, in section 3 the methodology used to assess the air quality is presented and in section 4 some experimental results on some areas of Palermo are presented, finally in section 5 some conclusions are drawn.[3-4]

Urban Waste as Resource for Sustainable Environment

The emerging model of waste disposal, develops an integrated approach based on waste reduction, selection, recycling, energy recovery and residual use of landfill. Here we discuss the fundamentals of a proper planning of waste disposal system, specially the thermal recovery, the integration and the methodological approach, either from the environmental and economic point of view. The growing demand for energy, the resulting environmental problems due to satisfy the demand for energy and the complex-economic system, necessitate the study of new technologies such as energy from municipal solid waste (MSW) obtaining as a result of decrease huge mass of solid waste to sanitary landifill and emissions of landifill gas as (CH4 and CO2 ). Therefore, we propose to validate a technical, economical and environmental analysis of waste-treatment systems with enphasis on generation of energy. The recovery of heat from a waste-to-energy plant, can make a useful contribution to the city energy needs. Whilst we have been slow to exploit fully this resource in Sicily, economically in urban areas.
