The main goal of the STREAMER Task 8.3 is to determine and recommend the most effective technologies for use to increase energy efficiency in newly build and retrofitted healthcare buildings in order to progressively enrich Healthcare Districts (HDs) with energy efficient, passive and zero energy buildings.

Moreover this task will promote at European level BIM and ICT building design practices which should result in significant cost- and time-wise improvement of EeB HD design processes and in increased competitiveness of the European AEC (architectural, engineering and construction) industry.

The main activities undertaken by the research teams included:

• Overview of legislation, standards and best practices in developing newly build and retrofitting existing HD buildings.
• Determination of  the specific requirements for design of HD buildings under national and EU laws, including the efficiency and reliability of energy supply.
• Determination of the specific local conditions, including climate, that influence technological solutions selection for securing targeted energy and economy efficiency.
• Definition of the quantitative criteria based on the review of available standard regulations (e.g. comfort, air quality, fire safety) applicable in design, construction, operation and maintenance indicating necessary evolutions in the set of existing regulations and standards.
• Indication of the need for preparation of future design standards reflecting on: best practices, guidelines and standards, special IT tools, numerical simulation and design programs.
• Assessment and implementation of the most relevant means to leverage existing processes and foster BIM Europe-wide breakthrough – e.g. best practices dissemination, ‘code of practice’, regulatory constraints, etc.

Based on the outcomes from the demonstration activities, Task 8.3 should elicit and shape the specific EeB HD methodological design guidelines based on semantic labelling methodology of new HD design.

The aim of the project is to reduce energy demand as well as CO2 emission of Health Care Districts by 2030 at least by 50%.

In the course of the STREAMER development the project team decided to concentrate on the early design stage of EeB HD development due to the fact that the design development and decisions made at this early stage are decisive for  energy demand of the designed HD buildings, engineering costs, investment expenses and future exploitation conditions. The early design stage forms a technical base for tendering, final detailed engineering and construction works. In order not to aggravate early design costs and time of the early design stage and enabling  execution of complex analyses in a short time, the STREAMER team decided to develop a design methodology supported by dedicated computing tools for EeB HD modelling, energy calculations and simulation studies to engineer optimal final EeB HD arrangement. 

The Key Research Target is to develop an early design methodology of HD EeB which accommodates:

• HD specific requirements, decision criteria and priorities;
• Analysis of HD energy performance and economy in HD life cycle;
• Engineering costs reduction;
• Interoperability of BIM and GIS with a set of necessary software interfaces.

The research project focuses on shortening early design processes in 3 main aspects of HD design and engineering:

• Building envelope and its spatial layout;
• MEP/HVAC installations;
• Hospital Campus Energy Grid managed by dedicated BMS software energy management methodology.

The targeted framework of the STREAMER Project enabling life cycle modelling of HD energy performance at the early design stage is a STREAMER Semantic EeHDB approach consisting of:

• SBEM – STREAMER HD Building Energy Modelling;
• SBIM – Semantic Building Information Modelling;
• SLCC – STREAMER HD LCC Modelling;
• SMPV – STREAMER HD Master Plan Validation.

The above approach supported with GIS data (Geographic Information System) forms STREAMER EeB HD early design methodology presented in this Deliverable, which consists of 2 parts:

• Report on undertaken research activities within the STREAMER Project and drawn conclusions for new and retrofitted EeHDBuildings standardisation;
• Standard proposal draft of STREAMER approach to EeHDBuildings Early Design Methodology – Master Plan Design.

The  recommended by STREAMER Project standard proposal draft presents methodology of an early design process for energy related EeHDBuildings design, engineering and construction:

• EeHDBuildings Terminology & Definitions;
• EeHDBuildings Energy Demand and Consumption Modelling;
• EeHDBuildings Goals, Comfort and Safety requirements;
• EeHDBuildings Semantic Modelling;
• EeHDBuildings LCC analysis and NPV Calculation;
• EeHDBuildings KPIs calculations and final HD solution validation.
