5 SITE PARAMETERS - Microclimate Climate (sunshine, temperature and wind) has a crucial influence on all design decisions and parameters such as orientation, glazing, thermal mass, insulation, ventilation and zoning. Careful consideration of the above issues at the earliest stages of a design can have an enormous impact on reducing subsequent operating costs. 1. Sunshine Design issues Thermal and Visual comfort Heating Cooling Lighting 1.Surface to volume ratio 1. Shading 1. Windows 2. Insulation 2. Exterior colors 2. Glazing 3.Infiltration 3. Insulation 3. Interior finishes BME Department of Building Constructions Project Design fall

6 SITE PARAMETERS - Microclimate 2. Wind effects Orientation and filtration Wind patterns around a building - related problems: wind pressure, natural ventilation, air infiltration, driving rain, smoke distribution, energy consumption of building, street comfort, air change, air pollution in urban spaces.

7 DESIGN PROCESS Basic function of new building CO-OFFICE HOUSE Architecture and engineering co-office building: foyer, reception: 40 m2 / ground floor coffee shop + storage: m2 / ground floor multipurpose hall: 60 m2 (divisible) / ground floor toilets: ~10 m2 (for disabled) / ground floor garbage: 10 m2 / ground floor office to rent: ~400 m2 (divisible) / upper levels meeting rooms: 20 m2 / every upper level copy area: 10 m2 / every upper level kitchenette: 10 m2 / every upper level toilets: ~15 m2 / every upper level workshop: 20 m2 / lower level storage: 8x8 m2 / lower levels changing room + shower: ~20 m2 / lower level garage (car elevator needed):for 12 cars + 12 bikes / lower level server room: 10 m2 / lower level room for installation: 20 m2 / lower level room for electricity: 10 m2 / ground floor room for ventilation: 40 m2 / roof level circulation area (staircase, elevator, corridors): as required BME Department of Building Constructions fall

8 DESIGN PROCESS Aspects & tools of energy saving Compact building form, shading, orientation Airtight construction of the building shell Very strong thermal insulation for walls and roof Very good windows, with coated multiple glazing An energy efficient, draft free ventilation system that provides a high-quality indoor environment, including plenty of fresh and filtered air Water based heating and cooling featuring chilled/heated floors, walls, beams, and ceilings which results in even and efficient distribution. Integration of renewable forms of energy such as geothermal, solar, wind, or wood. Use of waste heat. Careful selection of materials to avoid indoor and outdoor toxicity and to promote green values. Efficient household appliances and lighting. (MINERGIE Standard) Építész: Mikó László BME Department of Building Constructions Project Design fall

9 DESIGN PROCESS Tools for energy saving micro-grid smart grid systems for providing heat and electricity supply biomass-based combined heat and electricity production, heat pump heating and cooling use of recycled insulation use of bio-climatic principles in design, architecturally integrated active and passive solar systems, sunspaces, green roofs and green facades, effective summer heat protection with innovative shading development of large seasonal temperature reservoirs BME Department of Building Constructions fall

12 LOW-ENERGY DESIGN TOOLS Orientation of building The local climate see the microclimate of the site; Free solar contributions: they depend on the orientation of the building, on the position and on the size of the windows and on the outer solar masks. Architectural specifications: complexity of the form and surface as well as orientation of the windows (even with a very high performance level they are far from achieving the thermal performance of a solid wall) Kép.
