Modelling Method

The article deals with the methods of using and improving the work of the simulation modelling method in architectural design. As a result, the authors have tried to optimize their work with criteria such as energy demand, environmental impact, geometry, and materials. The rational use algorithm of these software products in the integrated design of energy efficiency improvement of buildings, complexes and urban structures have been proposed

The growing world-wide energy demand and environmental considerations have attracted immense attention in building energy efficiency. Climate zone plays a major role in the process of decision making for energy efficiency projects. In the present paper, an office building located in Melbourne, FL is considered. The building is built in 1961 and the goal is to identify and prioritize the potential energy saving opportunities and retrofit the existing building into a Net-Zero Energy Building (NZEB). An energy assessment is performed and a baseline model is developed using eQUEST to simulate the energy performance of the building. Several possible energy efficiency improvement scenarios are considered and assessed through simulation including improving insulation on the walls and roof, replacing HVAC units and upgrade their control strategies, use of high efficiency lighting, and more. Selected energy efficiency improvement recommendations are implemented on the building model to achieve the lowest energy consumption. It is considered that photovoltaic (PV) panels will be used to supply the energy demand of the building. Simulations are also performed to determine the number of required PV panels and associated cost of the system is estimated. The results from this paper can help with the decision making regarding retrofit projects for NZEB in humid subtropical climate.

The ubiquitous discrepancies between predicted and actual outcome of energy efficiency improvement have attracted much attention of the Chinese experts in the field of household energy efficiency. But few people in China realize that it is rebound effect that induces such discrepancies, which at present has been widely accepted in the developed countries. First, in this article the definition and formation process of the rebound effect in the household sector have been described. Then, a high rebound effect of at least more than 30% and more than 50% has been perceived through the combination of the actual situation of China and the experience of other countries. Finally, the influence of the rebound effect in the household sector has been proven negative on the energy demand and energy security of China.

Business As Usual

Materials are everywhere and have determined society. The rapid increase in consumption of materials has led to an increase in the use of energy and release of greenhouse gas (GHG) emissions. Reducing emissions in material-producing industries is a key challenge. If all of industry switched to current best practices, the energy-efficiency improvement potential would be between 20% and 35% for most sectors. While these are considerable potentials, especially for sectors that have historically paid a lot of attention to energy-efficiency improvement, realization of these potentials under current ‘business as usual’ conditions is slow due to a large variety of barriers and limited efforts by industry and governments around the world. Importantly, the potentials are not sufficient to achieve the deep reductions in carbon emissions that will be necessary to stay within the climate boundaries as agreed in the 2015 Paris Conference of Parties. Other opportunities need to be included in the menu of options to mitigate GHG emissions. It is essential to develop integrated policies combining energy efficiency, renewable energy and material efficiency and material demand reduction, offering the most economically attractive way to realize deep reductions in carbon emissions. This article is part of the themed issue ‘Material demand reduction’.
