Performance and Costs of Air Sealing and Ventilation Measures for Home Decarbonization in the US

In order to get to scale and rapidly decarbonize the energy use of homes, we need information on the performance and costs of potential home upgrade measures. The costs for different performance levels are vital for energy savings and decarbonization program planning and to focus R&D activities on measures that could achieve significant cost reductions. This study obtained data from over 1,700 projects that aimed to achieve advanced levels of energy use and related carbon emissions reductions.

Thermal envelope quality versus nZEB parameters and long-term economics: the Eco-Silver House case in Ljubljana

In 2014 the first multi storey residential building planned and constructed to meet the Passivhaus Institute (Darmstadt) criteria was put in operation in Ljubljana, the capital of Slovenia. This massive-structure building is part of the FP7 EE-Highrise project, aiming to demonstrate nearly zero energy building (nZEB) technologies, an integrated design concept, and advanced systems for sustainable construction.

Simulating life cycle cost for indoor climate systems

The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance. For example, the energy use could decrease. There has been a lack of knowledge, models and simulation tools for determining the life cycle cost (LCC) for an indoor climate system. The objective of this paper is to present a model for calculating the LCC for indoor climate systems. Focus is on indoor climate systems for premises and dwellings.

Different facade solutions: energy and cost performance Computational analysis of sixteen case studies in Sao Paulo and Rio de Janeiro, Brazil.

This work evaluates the performance of different façade solutions, comparing simulation results of glass type and (internal and/or external) solar protection, in the cities of São Paulo and Rio de Janeiro, Brazil. For the simulations, it was considered as

An engineering approach to ventilation system design.
