When the cascade heat pump system is applied as a multi-functional that can be used not only for hot water supply but also air-conditioning of buildings, low-stage cycle responsible indoor heating and cooling thermal load, high-stage by raising refrigerant temperature. Unlike existing designed with one operation mode supply, should considered various parameters. This study was proposed design s...

The objective of this paper is to estimate the potential for electricity savings with the use of daylighting integrated with the artificial lighting system and hybrid ventilation in commercial buildings located in Florianópolis, southern Brazil. Several models were analysed. Two cases were investigated: a reference case, operating only with air-conditioning system and another one with the use o...

Planning energy-efficient buildings which produce on-site renewable energy in an urban context is a challenge for all involved actors in the planning process. The primary objective of this study was to develop a façade assessment and design tool for solar energy (FASSADES) providing the necessary information for all stakeholders in the design process. The secondary objective was to demonstrate ...

A novel dynamic simulation model for the building envelope energy performance analysis is presented in this paper. This tool helps the investigation of many new building technologies to increase the system energy efficiency and it can be carried out for scientific research purposes. In addition to the yearly heating and cooling load and energy demand, the obtained output is the dynamic temperat...

In the cold sunny winter days, when the south wall is well insulated, a significant amount of solar energy falling on this facade is not transferred to the inside. In this study, a novel closed wall-loop system is proposed to capture this wasted energy available during non-cloudy winter days and transfer it to the cooler north facade through water pipes embedded in an exterior aerogel-based ins...

Intelligent building automation systems can reduce the energy consumption of heating, ventilation and air-conditioning (HVAC) units by sensing the comfort requirements automatically and scheduling the HVAC operations dynamically. Traditional building automation systems rely on fairly inaccurate occupancy sensors and basic predictive control using oversimplified building thermal response models,...

A well known heuristic sets the length of an overhang as the intersection of lines joining window's top and bottom edges with the respective positions of the sun during the solstices, thus providing complete shade during the summer solstice and full insolation during the winter solstice. The solstices, however, are just two isolated moments, while the solar energy influences building's heat bal...

This paper presents a simulation study to reduce heating and cooling energy demand of a school building in Seoul Metropolitan Area, Korea. The aim of this study was to estimate the impact of passive vs. active approaches on energy savings in buildings using EnergyPlus simulation. By controlling lighting, the energy saving of the original school building design was found most significant, and in...

This paper uses SketchUp and OpenStudio to design optimize the multiperformance parameters of near-zero energy consumption residential building scheme stage. By establishing a basic model, performance such as insulation thickness, typical outer window, window-to-wall ratio, their contribution rates within threshold range are optimized for conservation; simulate determined parameter combination ...
