High performance solutions and data for nZEBs offices located in warm climates.

This data article contains eleven tables supporting the research article entitled: Cost-Optimal Design For Nearly Zero Energy Office Buildings Located In Warm Climates [1]. The data explain the procedure of minimum energy performance requirements presented by the European Directive (EPBD) [2] to establish several variants of energy efficiency measures with the integration of renewable energy sources in order to reach nZEBs (nearly zero energy buildings) by 2020. This files include the application of comparative methodological framework and give the cost-optimal solutions for non-residential building located in Southern Italy. The data describe office sector in which direct the current European policies and investments [3], [4]. In particular, the localization of the building, geometrical features, thermal properties of the envelope and technical systems for HVAC are reported in the first sections. Energy efficiency measures related to orientation, walls, windows, heating, cooling, dhw and RES are given in the second part of the group; this data article provides 256 combinations for a financial and macroeconomic analysis.

Data of cost-optimality and technical solutions for high energy performance buildings in warm climate

The data reported in this article refers to input and output information related to the research articles entitled Assessment of cost-optimality and technical solutions in high performance multi-residential buildings in the Mediterranean area by Zacà et al. (Assessment of cost-optimality and technical solutions in high performance multi-residential buildings in the Mediterranean area, in press.) and related to the research article Cost-optimal analysis and technical comparison between standard and high efficient mono residential buildings in a warm climate by Baglivo et al. (Energy, 2015, 10.1016/j.energy.2015.02.062, in press).

Modelling of Wetting and Drying Cycles in Building Structures

Many buildings are frequently subjected to deterioration caused by dampness, whose effects can be amplified by structure material properties, and microclimatic conditions. This contribution proposes a quantitative model to perform a physical analysis of rising damp. The main driving forces which control the process were identified and expressed in formulae that involve generally obtainable microclimatic data. Wetting and drying cycles were analyzed to understand the periodic behaviour due to absorption and evaporation of moisture into and out of the structure. The model was applied to a field study to derive physical quantities that are not usually calculated in monitoring plans, such as the amount of water stored, the drying flow rate and the time-scale for drying. The daily evaporation rate was finally computed over a five year period and the harmonic equation fitting the curve was determined by considering meteorological data. The model showed that the drying capacity of the micro-environment was a primary factor in seasonal variations of the total flow through the building which lead to long-term damage. The developed model allowed much information on moisture cycles and on the associated deterioration of the structure to be obtained.
