Evaluation of ventilation solutions for retrofitting of schools

In 2011, the Danish Energy Agency initiated a study into ventilation solutions for the retrofit of schools to identify the most promising technologies. The reason was an increasing awareness that the ability of school children to absorb, adapt and use knowledge was affected negatively by inadequate ventilation rates. This paper presents an output of this study. A method for evaluation of the ventilation systems is proposed. The method consists of three categories with a clear separation to create a scoring board that facilitates transparent and unbiased evaluation.

The impact of airtightness in the retrofitting practice of low temperature heating

In Sweden, the energy usage in existing residential buildings amounted to 147 TWh in 2012, equivalent to almost 40 % of the final overall national energy usage. Among all the end users in building service sectors, 60 % of the final energy in Sweden is used for space heating and domestic hot water (DHW) production in 2013.

The retrofit of respiratory isolation rooms for tuberculosis patients in Taiwan

In order to effectively control nosocomial infection 12 respiratory isolation rooms fortuberculosis patients in four hospitals have been built by the Energy & Resources Laboratories,Industry Technology Research Institute in Taiwan. This project was funded by the Center ofDisease Control of the Health Department. The performance of the air-conditioning andventilation/exhaust system of respiratory isolation rooms has been tested and validated. Thetested items include ventilation rate, static pressure, temperature, humidity and noise.

VOC and fine particles in a newly renovated building: a case study

In a small case study involving an office room and a laboratory in a building equipped with aHVAC system VOC and particle samples were collected. Both rooms used for theexperiments were newly renovated and low, but measurable amounts of typical indoor VOCand SVOC were present in the air several weeks after finishing of the renovation work. TheVOC concentrations decreased slowly during the test period of 3 weeks.Particulate matter in the room air was characterized regarding the size distribution bySMPS.

Europrosper : Developing methods for the energy certification of existing buildings.

This paper outlines the Europrosper project whose objectives are to :1. Consolidate and where appropriate harmonise methodologies for energy certification of existing office buildings across 6 European countries whilst allowing customisation in each country to accomodate existing techniques and national contexts2. Develop training courses to instruct practitioners on how to use the certification methods, to include self-certification procedures3. Conduct a demonstration phase and4.

Ventilation stratefies of a residential district on restoration : analysis of technical solutions and comparative evaluation.

Within an Italian Experimental Programme an interdisciplinary research for the retrofitting of some residential buildings in the surrounding of Florence has been carried out. The activity of the experimental research concerns the methodological and scientific support to the technical solutions for the restoration of two buildings.

The transformation of the conservatorio San Giuseppe into the cospicua residential home for the elderly, Malta

The transformation of the Conservatorio San Giuseppe , into the Cospicua Residential Home for the Elderly has become a landmark in the neighbourhood. It brings past and present together with its old church and stepped new development incorporating a colourful orange windbreak. It is an example of how an old building, originally an orphanage for girls, with limitations of location and orientation could be rehabilitated to incorporate energy efficient features. Both the original structure and the new construction are load bearing with a high thermal mass to utilise a direct gain system.

Sustainable architecture and energy efficiency in a retrofitted museum

The Portuguese National Museum for Archaeology is undergoing an expansion and retrofitting. It is currently housed in one of the most important ancient monuments in Portugal: the Monastery of Jernimos. The authorities responsible for the museum, taking advantage of this retrofitting, decided to promote a modern and integrated design of the future archaeological museum. The architectural design aims to combine, aesthetically, the old and the new building, promoting sustainable architecture and energy efficiency (concerning, essentially, indoor climate, lighting and acoustical requirements).

Reconstruction for slovene ethnographic museum

Reconstruction of late 19 th century building for new Slovene Ethnographic Museum is presented. Interventions into building envelope and heating, cooling and lighting system from exhibits and visitors comfort and rational use of energy point of view were treated in the framework of EU and SI research programmes. An innovative heating-cooling system have been designed and tested.

Integration of high environmental quality comfort requirements during the retrofitting of educational buildings.

A important part of educational buildings must be retrofitted in many European countries, in the next years, for historical and demographic reasons. These retrofittings must be carried out with a limitation of energy consumption and a better indoor comfort. In this context, Annex 36 of International Energy Agency aims at promoting energy efficient measurements of educational buildings in the retrofitting process. In the same time, in France, decision makers want to integrate high environmental quality comfort requirements.
