AbstractThe article raised issues related to the design and execution of low-energy objects in Polish conditions. Based on the designed single-family house, adapted to the requirements of the National Fund for Environmental Protection and Water Management (“NF40” standard), the tools to assist investment decisions by investors were shown. An economic analysis and a multi-criteria analysis were performed using AHP method which had provided an answer to the question whether it is worthwhile to bear higher investment costs in order to adjust to the standards of energy-efficient buildings that fulfil a minimal energy consumption's requirements contained in Polish law. In addition, the variant of object that had optimal characteristics due to the different preferences of investors was indicated. This paper includes analysis and observations on the attempts to unify that part of the building sector, which so far is considered to be personalized, and objects in accordance with the corresponding idea are designed as “custom-made”.

Energy Efficient Building

Housing development, as part of the economic development must be supported by energy availability in order to obtain a sustainable growth. One of the approaches to support the renewable energy promotions is designing and building energy efficient housing. However, optimal design of energy efficient buildings is facing two conflicting requirements, namely cost effective consideration and minimum environmental impact. The high costs from energy efficient building such as the Near Zero Energy House (nZEH) is due to high price of materials and equipment used, such as solar panel, insulation and other supporting materials. Indonesia is situated at the equator and received sunlight throughout the year. Nonetheless, this potential has not been fully discovered due to the high cost of the solar generated energy technology for housing. Moreover, this technology is not integrated with the main electricity network. Thus, the objective of this study is to identify the design variables for nZEH that suit the tropical climate condition in Indonesia. Experiments and Case Study are used for the study, and the validated design variables for nZEH, which includes building orientation, PV, fenestration, and passive design, will be the basis for optimum nZEH design.

As part of this study, an issue has been identified with regards to there being a performance gap with energy efficient buildings. This has been validated through literature review in the areas of occupancy behavior, modeling accuracy and reviewing energy consumption of energy efficient buildings. In order to analyze the error generated between predicted and actual energy performance, a case study approach has been adopted. The Ron Joyce Centre is a LEED Gold Certified building that is part of the McMaster University campus in Burlington. Actual energy performance data has been collected along with detailed drawings to analyze its predicted energy performance using real weather data over a two-year period in eQUEST. The results indicate that eQuest is able to predict electrical consumption within 0.72% of actual on an annual basis. However, natural gas consumption is more erratic and inconsistent based on heating degree days and has fluctuating values with differences ranging between 21% to 4.5% on monthly basis. The overall predicted energy consumption for 2012 is 1096133 kWh and 33227 m

Important Position

Energy-efficient buildings utilise the potential of renewable sources, among which heat pumps hold an important position. As this technology has a secondary effect on the environment through its noise immission, locations of outdoor units in the exterior should be subjected to the assessment. The present article deals with the options of placing heat pumps in the exterior and the placement assessment methods. The noise burden identification through the assessment of the time exposure is presented in the example of an in situ measurement.
