Evaluating the present day ambient warming resilience of passively cooled dwellings in Ireland: A data-driven approach

The use of the word “resilience” has increased significantly since 2010, however, there is a lack of understanding around 1) how thermal resilience is defined (where some definitions were offered only recently) and 2) what distinguishes it from typical overheating assessments. In addition to this, there is a lack of uptake in the remote monitoring industry (which uses low-cost solutions) when it comes to typical parameters used in thermal comfort studies and there is need to demonstrate how resilience performance can be reported going forward.

Use of low cost IAQ sensors?

The difficulty in measuring IAQ indicators like VOCs and particles, lies in the multiplicity of the composition of these pollutants. Analysis of the responses of some low cost IAQ sensors when subjected to real sources of pollution shows that they do not react homogeneously, due to their sensitivity and post-treatments. These sensors can be used by consumers to understand the effect of their actions on the evolution of IAQ indicators, not to rely directly on the values displayed.

Introduction to demand controlled ventilation in France

Demand controlled ventilation systems are representing a large majority of installations in France. They are commonly used for more than 35 years. The strong development of these systems can be explained by the French regulatory framework for air renewal. These demand controlled systems have been developed in order to optimise the energy consumption and at the same time to ensure indoor air quality and building durability. In residential buildings, demand control is based mainly on humidity whereas in commercial buildings it is based on occupancy and/or CO2 levels.

Uncertainties in different level assessments of domestic ventilation system

In order to improve the quality of ventilation systems, assessments are widely used. In this paper, 3 main assessment levels are distinguished based on the number of ventilation systems to be assessed and the assessment objective.

Demand-controlled ventilation: An outline of assessment methods and simulation tools

Enhancing the energy efficiency of buildings imposed by global warming and by the perspective of fossil fuel dwindling requires new technical solutions, more efficient. The race for efficiency directly affects ventilation and air tightness of buildings, the main potential causes of heat loss in homes. If heat recovery is emerging as an effective solution to meet energy performance and indoor air quality in climates with harsh winters, some other solutions appear to be very efficient in moderate climates.

An Energy Efficiency Oriented Analytic Network Process for Intelligent Buildings Assessment

This paper presents a multicriteria decision-making model for lifespan energy efficiencyoriented intelligent buildings (IBs) assessment. The model called IBAssessor isdeveloped using the theory of analytic network process (ANP) method, and a set oflifespan performance indicators, which are selected by a new quantitative approach calledenergy-time use index (ETI).


Since our earth has finite material resources and biological capacity, human must live within thecarrying capacity on the earth.As we exceed the carrying capacity of the earths ecosystem over thetime they stressed, then go into decline and finally collapse. They are expanded further than renewed.The construction and operation of built environment contribute to the environmental loads. Those whodesign and purchase building have little or no methods to asses the environmental impact of theiractions.


Malaysia is situated near the equator of earth where the weather is hot and humid. The vulnerableenvironment has induced many Indoor Air Quality (IAQ) concerns in hospitals by health professions inmany countries. There is mounting evidence on IAQ exposure leading to excessive morbidity andmortality. Many extensive studies have been conducted but there is not many IAQ standard to-date.The objective of the study is to present the finding of the source of indoor air quality in a new hospital inMalaysia. The study also presents the solution to overcome the IAQ problem faced by the hospital.
