In research and assessment of indoor environmental quality (IEQ), the terms ‘Comfort’, ‘Health’ ‘Well-being’ are often used interchangeably without a clear definition or effects on conditions for occupants. This calls systematic restructuring ontological approach to IEQ and, based meta-analysis recent literature, authors suggest three substantial contributions: 1) A framework consisting comfort, health well-being as equal branches increase focus previously neglected aspects make inter-domain...
The operational building data presented in this paper has been collected from six office rooms located an (research and educational purposes) on the main campus of Aalborg University Denmark. dataset consists measurements occupancy, indoor environmental quality, room-level system-level heating, ventilation lighting operation at a 5-minute resolution. quality system were management system. occupancy level each monitored room is established computer vision-based analysis wall-mounted camera...
With the aim to increase today's low retrofitting rate and thus decrease currently rising energy consumption of building sector, this work proposes a novel renovation concept for schools. Therefore, two components, double skin facade (DSF) diffuse ceiling ventilation (DCV), are combined with an exhaust system, providing alternative traditional where windows replaced, external wall is insulated balanced system installed. Further, based on Danish case study classroom, different configurations...
The study in this article investigates 15 ventilated window typologies with different pane configurations and glazing types climates of four European countries (United Kingdom, Denmark, France Germany) order to identify the optimum typology regard their energy balance impact on thermal comfort. Hourly simulations heat balances windows are conducted days representing typical weather conditions according method described EN ISO 13790. U g values used calculation calculated software tool (WIS)...
There is very little knowledge on the occupant actual hot water comfort (temperature and flow), usage practice, routines (temporal spatial distribution of in a household). This paper describes results from total measurements two Danish detached houses. The show that, at draw-off points, temperature 55 °C never asked by occupants, not even kitchen sink. domestic differentiates depending function point, with shower taps being most energy- water-intense. They constitute around 90% use house....
A novel renovation solution was proposed recently by integrating diffuse ceiling ventilation and double skin façade. This study presents an experimental investigation on the performance of in a small-scale classroom. The aim this to evaluate potential combining principle with double-skin façade through thermal comfort passive energy evaluation two operation modes: heating mode cooling mode. compared traditional installed identical room. results showed that achieved comparable or even...
Much effort has been put in tightening the building regulations. Though, energy usage for domestic hot water stayed unchanged constituting a bigger share of pie over years. Due to cost, timeframe, and workload associated with instrumentation installation, vast majority DHW measurements are limited household level. This paper introduces high resolution measuring technique consumption its application single family house. By applying this technique, we able measure duration, flow temperature...
A growing focus on occupant comfort, health and wellbeing has resulted in attempts to quantify indoor environmental quality (IEQ) determine the relative contributions of single IEQ aspects an overall index. The recently developed IV20 tool assesses potential label IEQ, assign separate scores for main environment (IE) areas: thermal, visual, acoustic air quality. In absence objective, universally applicable weights, this paper develops executes a methodology asking regional experts with...
Credible building modelling is essential to the energy certification and renovation towards better performance indoor climate. The primary objective of this work assess consequences related level effort necessary simulate geometry its facilities guide practitioners in by providing insights about model simplification both for comfort. This focuses on sensitivity heating system influence these thermal comfort KPIs standard simulation conditions. Moreover, study presents models verification...
Artificial lighting represents 15-30% of the total electricity consumption in buildings Scandinavia. It is possible to avoid a large share use for by application daylight control systems artificial lighting. Existing methodology estimation with such Norway based on Norwegian standard NS 3031:2014 and can only provide results from rough estimate. This paper aims introduce new usage daylight- occupancy-controlled an office, which both accurate rapid. The method validated office building Oslo,...
Research and practice agree that decisions taken early in a project have higher impact are less costly. Current building performance assessment methods not suited to accommodate the responsiveness required for design processes often used validation later stages where feedback has little impact. Tools developed specifically early-stage Design Decision Support (DDS) either too simplistic, provide no solution addressing combined indoor environmental quality (IEQ), or risk worsening overall IEQ...
With the aim to offer an alternative renovation concept for schools and thus contribute a better indoor environmental quality reduced energy consumption, system combining diffuse ceiling double-skin facade with existing exhaust ventilation (I-DIFFER) was proposed in previous work by authors. The initial analyses of novel were promising, showing potential 11 % reduction primary consumption compared traditional where insulated, windows replaced balanced installed. Consequently, this further...
Abstract The energy performance certification (EPC) scheme, introduced in the European Union approximately 20 years ago, has become focus of upcoming revision Energy Performance Buildings Directive (EPBD). Despite its widespread use, current EPC scheme several shortcomings that need to be addressed. flexible DYnamic building Certification (E-DYCE) project developed a dynamic approach address these issues. methodology includes assessment building’s needs and comfort conditions under standard...
Ventilated facades are applied in both new and existing buildings. It has been claimed that these components help to reduce energy use buildings improve occupant comfort. However, their performance strongly depends on the airflow passing through cavity. In order characterise model behaviour of ventilation its effectiveness, need be tested laboratory, as well under real dynamic weather conditions. Despite steadily growing research this area, there few studies with conclusive results about...
