Design And Construction

Currently, the construction of low energy buildings in Europe is promoted. Existing and newly developed design and construction concepts for such buildings are adapted to their national or regional climatic conditions. The European Parliament has assigned the member countries to get ready for the reduction of the energy consumption in buildings. Therefore, Lithuania, like other EU countries, must be examined for the use of the low energy building design and construction experience, the existing concepts of low energy buildings should be adapted or new concepts of low energy building responding to the region's climate should be created. In this article, the most popular European mid‐region passive house concept and the energetic performance of the house, designed and built according to its requirements is analyzed, the main differences of this concept to the normative requirements of Lithuanian building regulations and proposals to improve provisions for the construction of low energy buildings in Lithuania is provided. Santrauka Šiuo metu Europoje skatinama mažai energijos vartojančių namų statyba. Esamos ir naujai kuriamos tokių namų projektavimo ir statybos koncepcijos dažniausiai pritaikytos konkrečios šalies arba regiono klimato sąlygoms. Europos Parlamentas įpareigojo šalis nares pasirengti mažinti pastatuose suvartojamos energijos kiekį. Todėl Lietuvoje, kaip ir kitose ES šalyse, turi būti išnagrinėta mažai energijos vartojančiių pastatų projektavimo ir statybos patirtis, perimtos jau taikomos arba sukurtos naujos koncepcijos, tinkamos šio regiono klimatui. Straipsnyje išanalizuota populiariausia Vidurio Europos regione pasyviojo pastato koncepcija, pagal jos reikalavimus suprojektuoto ir pastatyto namo energiniai rodikliai, nustatyti pagrindiniai šios koncepcijos ir Lietuvos statybos norminių dokumentų reikalavimu skirtumai ir pateikti pasiūlymai gerinti sąlygas mažai energijos naudojančiu pastatu statybai Lietuvoje.

Low Energy Buildings

Passivhaus or Passive House buildings are low-energy buildings in which the design is driven by quality and comfort, hence achieving acceptable levels of comfort through post-heating or post-cooling of fresh air. Additionally, Passivhaus building design follows the Passivhaus design criteria, as described in the Passive House Planning Package (PHPP). This article aims to introduce the Passivhaus background, development, and basic design principles. Finally, it also presents a brief description of the performance of Passivhaus buildings.

Wind Comfort

There is a distinct lack of building design literature specific to the Central Asian region. This perhaps, could be one of reasons for the only slight improvement of new building designs and construction. One does observe the highly glazed buildings are a particularly popular feature here in Astana, as like anywhere else in the world. However, excessively glazed surfaces combined with the weather extremes leads to adverse internal conditions and skyrocketing energy bills. The work presented in this paper is a part of continuing efforts to identify analyze and promote the design of ‘low energy, green and sustainable buildings with special reference to the Kazakhstan locality. In the present context, low energy buildings’ refers to buildings inherently low energy consuming by careful passive design, utilizing intelligent building technologies to automate building services and minimize wastage of energy and by incorporation of renewable technologies for its energy supply. Demonstration of improved environmental conditions and impact on energy savings will be outlined through a cause study incorporating application of passive design approach and detailed computational fluid dynamics (CFD) analysis for an existing building complex. The results indicated that there is a considerable influence of passive design and orientation on energy efficiency, wind comfort and safety.

Factor Interactions

The low energy building concept is based on improving the building envelope to reduce heating and cooling loads. Improvements in building envelopes depend not only on climatic conditions but also on insulation. In this study, the thermal performance of external walls was studied by using a three-level full factorial statistical experimental design. An opaque wall in low energy buildings was chosen in order to study the effect of selected factors of city (A), orientation (B), insulation location (C), and month of the year (D) on heat loss or gain. A software was used to calculate the ANOVA table. As a result, all three factors of months of the year, city and orientation of the building fa?ade were found to be significant factor effects for heat transfer. Two-factor interactions of AB, AD, BD, and CD were found to be significant. Therefore, the effects of season, location and orientation were successfully shown to be effective parameters.

Study Case

Abstract We propose a model that aims to fulfill the following three necessities: the demand for refurbishing the existing built environment, the lack of a reliable means to help architects navigate among the numerous possible solutions for low-energy constructions, and the need for a multi-function tool to analyze buildings as complex systems. We introduce the Optimal Refurbishment Design (ORD) model that is a novel tool to help architects with the refurbishment of an existing building or the design of a new one. The ORD shows four innovative aspects. First, it opens the way to passive building design while focusing on affordable solutions. Second, its core component is based on mathematical optimization. Third, it simultaneously outputs optimal thermal mass and insulation of all the required elements in the building. Fourth, it automatically accounts for the user’s needs and local regulations. Unlike most of the approaches in the Literature, the ORD’s outputs are not limited by any pre-defined set of materials or strategies. We tested the ORD using a realistic study case of refurbishment, and found that the renovated house achieved the energy consumption of a Passive House by lowering its annual heating/cooling consumption by 23% with a payback period of less than 5 years.

The Impact

Between the ages of 6 and 18, children spend between 30 and 42 h a week at school, mostly indoors, where indoor environmental quality is usually deficient and does not favor learning. The difficulty of delivering indoor air quality (IAQ) in learning facilities is related to high occupancy rates and low interaction levels with windows. In non-industrialized countries, as in the cases presented, most classrooms have no mechanical ventilation, due to energy poverty and lack of normative requirements. This fact heavily impacts the indoor air quality and students’ learning outcomes. The aim of the paper is to identify the factors that determine acceptable CO2 concentrations. Therefore, it studies air quality in free-running and naturally ventilated primary schools in Chile, aiming to identify the impact of contextual, occupant, and building design factors, using CO2 concentration as a proxy for IAQ. The monitoring of CO2, temperature, and humidity revealed that indoor air CO2 concentration is above 1400 ppm most of the time, with peaks of 5000 ppm during the day, especially in winter. The statistical analysis indicates that CO2 is dependent on climate, seasonality, and indoor temperature, while it is independent of outside temperature in heated classrooms. The odds of having acceptable concentrations of CO2 are bigger when indoor temperatures are high, and there is a need to ventilate for cooling.
