Energy renovation roadmaps for residential and non-residential buildings —
Energy efficiency and renewable energies
- Where can I get fossil-free heating, cooling and electricity?
- Which energy efficiency measures should I implement?
- What do construction and operation cost?
watts designs fossil-free energy solutions — determination of energy demand profiles, identification of available energy sources such as wastewater heat, geothermal energy and solar radiation as well as dynamic profitability analysis and assessment of the environmental impact are part of the concept.
Energy analysis and district heating check
The heating, cooling and power supply for the Toom store in Hanover was analyzed. The analysis focused on the economic analysis for the conversion of natural gas-based heat generation to district heating.
Refurbishment schedules for halls of residence
Refurbishment roadmap with measure cost estimate and energy savings forecast for two day care facilities with operational optimization
Energy-efficient refurbishment roadmap
Refurbishment roadmap with cost estimate for measures and energy savings forecast for the Albestrasse senior citizens’ residence in Berlin
Energy-efficient refurbishment roadmap and project management
Technical status analysis of the natural gas-based heating and cooling supply. Potential analysis of regenerative heat sources in combination with cooling and photovoltaics for several shopping centers with project management in the implementation phase
Project management heat pump, PV, ventilation
Techno-economic feasibility analysis for the use of air-source heat pumps in the retail center, optimization of ventilation incl. Implementation support with tendering of planning services, control of the implementation of heat pump, photovoltaic and ventilation system conversion.
Energy concept for logistics and shopping centers
Feasibility study with techno-economic variant evaluation. Objective: fossil-free heating and cooling supply for approx. 37,000 m² of floor space with local environmental heat and photovoltaics
Energy audit DIN 16247 and ISO 50.001 Energy management
Refurbishment roadmap for individual buildings and portfolios
- Where can I get fossil-free heating, cooling and electricity?
watts records the current status of energy-relevant systems such as heating, cooling, ventilation, lighting, the building envelope and building management systems, energy-saving measures are put to the techno-economic test and an individual refurbishment roadmap with a CO2 reduction path is developed.
Energy audit for 10 public buildings
Energy assessment of buildings and identification of energy-saving measures
Energy and CO2 audit with heating concept
Energy audit DIN 16247 for 20 buildings with techno-economic evaluation of measures and feasibility study for the conversion of local heating from natural gas to environmental heat
Energy audit with PV and heat pump check
Energy audit in accordance with DIN 1647 with implementation plan for measures such as steam generation, water heating and cooling waste heat utilization. Techno-economic pre-evaluation for the conversion from natural gas to environmental heat with a heat pump and the installation of a photovoltaic system.
Advice on energy contracting vs. own solution —
and implementation of contracting tenders
- Is energy contracting advantageous for financing, construction and operation?
watts compares the contracting solution with in-house implementation. A life cycle cost analysis is used to identify the best way forward and, if necessary, the right contractor is identified by means of a call for tenders.
Contracting competition for heat supply
Conceptual design of a bivalent air heat pump for the Dever Park in Papenburg and implementation of the energy supply contracting tender
Ecological-economic-technical evaluation
- Does the current energy planning fit my project?
- Are there options for reducing costs?
watts puts your energy planning to the independent test. The economic efficiency incl. Manufacturing and operating costs and possible subsidies as well as technical feasibility, approvability and the CO2 footprint.
Feasibility study “Blechenstrasse heating solution”
Feasibility study for the heat supply of a residential complex in Berlin: analysis of the existing natural gas-based situation, techno-economic comparison of district heating and heat pump solutions as possible alternatives with CO₂ price risk assessment. Goal: Efficient, resilient heat supply for 67 residential units.
PV Onsite PPA for logistics, retail, hotel and office
